i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below. The list might include ACKs from people not holding copyright on any parts of the reused code, but it's better to err on the side of caution and include them.

pc: hack for migration compatibility from QEMU 2.0 Changing the ACPI table size causes migration to break, and the memory hotplug work opened our eyes on how horribly we were breaking things in 2.0 already. The ACPI table size is rounded to the next 4k, which one would think gives some headroom. In practice this is not the case, because the user can control the ACPI table size (each CPU adds 97 bytes to the SSDT and 8 to the MADT) and so some "-smp" values will break the 4k boundary and fail to migrate. Similarly, PCI bridges add ~1870 bytes to the SSDT. This patch concerns itself with fixing migration from QEMU 2.0. It computes the payload size of QEMU 2.0 and always uses that one. The previous patch shrunk the ACPI tables enough that the QEMU 2.0 size should always be enough; non-AML tables can change depending on the configuration (especially MADT, SRAT, HPET) but they remain the same between QEMU 2.0 and 2.1, so we only compute our padding based on the sizes of the SSDT and DSDT. Migration from QEMU 1.7 should work for guests that have a number of CPUs other than 12, 13, 14, 54, 55, 56, 97, 98, 139, 140. It was already broken from QEMU 1.7 to QEMU 2.0 in the same way, though. Even with this patch, QEMU 1.7 and 2.0 have two different ideas of "-M pc-i440fx-2.0" when there are PCI bridges. Igor sent a patch to adopt the QEMU 1.7 definition. I think distributions should apply it if they move directly from QEMU 1.7 to 2.1+ without ever packaging version 2.0.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below. The list might include ACKs from people not holding copyright on any parts of the reused code, but it's better to err on the side of caution and include them.

pc: hack for migration compatibility from QEMU 2.0 Changing the ACPI table size causes migration to break, and the memory hotplug work opened our eyes on how horribly we were breaking things in 2.0 already. The ACPI table size is rounded to the next 4k, which one would think gives some headroom. In practice this is not the case, because the user can control the ACPI table size (each CPU adds 97 bytes to the SSDT and 8 to the MADT) and so some "-smp" values will break the 4k boundary and fail to migrate. Similarly, PCI bridges add ~1870 bytes to the SSDT. This patch concerns itself with fixing migration from QEMU 2.0. It computes the payload size of QEMU 2.0 and always uses that one. The previous patch shrunk the ACPI tables enough that the QEMU 2.0 size should always be enough; non-AML tables can change depending on the configuration (especially MADT, SRAT, HPET) but they remain the same between QEMU 2.0 and 2.1, so we only compute our padding based on the sizes of the SSDT and DSDT. Migration from QEMU 1.7 should work for guests that have a number of CPUs other than 12, 13, 14, 54, 55, 56, 97, 98, 139, 140. It was already broken from QEMU 1.7 to QEMU 2.0 in the same way, though. Even with this patch, QEMU 1.7 and 2.0 have two different ideas of "-M pc-i440fx-2.0" when there are PCI bridges. Igor sent a patch to adopt the QEMU 1.7 definition. I think distributions should apply it if they move directly from QEMU 1.7 to 2.1+ without ever packaging version 2.0.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below. The list might include ACKs from people not holding copyright on any parts of the reused code, but it's better to err on the side of caution and include them.

piix4: don't reserve hw resources when hotplug is off globally When acpi hotplug is turned off for both root pci bus as well as for pci bridges, we should not generate the related ACPI code for DSDT table or initialize related hw ports or reserve hw resources. This change makes sure all those operations are turned off in the case ACPI pci hotplug is off globally. In this change, we also make sure ACPI code for the PCNT method are only added when bsel is enabled for the corresponding pci bus or bridge hotplug is turned on. As q35 machines do not use bsel for it's pci buses at this point in time, this change affects DSDT acpi table for q35 machines as well. Therefore, we will also need to commit the updated golden master DSDT table acpi binary blobs as well. Following is the list of blobs which needs updating: tests/data/acpi/q35/DSDT tests/data/acpi/q35/DSDT.acpihmat tests/data/acpi/q35/DSDT.bridge tests/data/acpi/q35/DSDT.cphp tests/data/acpi/q35/DSDT.dimmpxm tests/data/acpi/q35/DSDT.ipmibt tests/data/acpi/q35/DSDT.memhp tests/data/acpi/q35/DSDT.mmio64 tests/data/acpi/q35/DSDT.numamem tests/data/acpi/q35/DSDT.tis These tables are updated in the following commit.

Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below. The list might include ACKs from people not holding copyright on any parts of the reused code, but it's better to err on the side of caution and include them.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory.

piix4: don't reserve hw resources when hotplug is off globally When acpi hotplug is turned off for both root pci bus as well as for pci bridges, we should not generate the related ACPI code for DSDT table or initialize related hw ports or reserve hw resources. This change makes sure all those operations are turned off in the case ACPI pci hotplug is off globally. In this change, we also make sure ACPI code for the PCNT method are only added when bsel is enabled for the corresponding pci bus or bridge hotplug is turned on. As q35 machines do not use bsel for it's pci buses at this point in time, this change affects DSDT acpi table for q35 machines as well. Therefore, we will also need to commit the updated golden master DSDT table acpi binary blobs as well.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory.

Technically there is no reason not to describe cold-plugged bridges (root ports) on functions other then 0, as they similarly to bridge on function 0 are unpluggable.

acpi-build: append description for non-hotplug As reported in http://article.gmane.org/gmane.comp.emulators.qemu/253987 Mac OSX actually requires describing all occupied slots in ACPI - even if hotplug isn't enabled. I didn't expect this so I dropped description of all non hotpluggable slots from ACPI. As a result: before commit 99fd437dee468609de8218f0eb3b16621fb6a9c9 (enable hotplug for pci bridges), PCI cards show up in the "device tree" of OS X (System Information). E.g., on MountainLion users have: Hardware -> PCI Cards: Card Type Driver Installed Slot *ethernet Ethernet Controller Yes PCI Slot 2 pci8086,2934 USB UHC Yes PCI Slot 29 ethernet: Type: Ethernet Controller Driver Installed: Yes MSI: No Bus: PCI Slot PCI Slot 2 Vendor ID: 0x8086 Device ID: 0x100e Subsystem Vendor ID: 0x1af4 Subsystem ID: 0x1100 Revision ID: 0x0003 Hardware -> Ethernet Cards ethernet: Type: Ethernet Controller Bus: PCI Slot PCI Slot 2 Vendor ID: 0x8086 Device ID: 0x100e Subsystem Vendor ID: 0x1af4 Subsystem ID: 0x1100 Revision ID: 0x0003 BSD name: en0 Kext name: AppleIntel8254XEthernet.kext Location: /System/Library/Extensions/... Version: 3.1.1b1 After commit 99fd437dee468609de8218f0eb3b16621fb6a9c9, users get: Hardware -> PCI Cards: This computer doesn't contain any PCI cards. If you installed PCI cards, make sure they're properly installed. Hardware -> Ethernet Cards ethernet: Type: Ethernet Controller Bus: PCI Vendor ID: 0x8086 Device ID: 0x100e Subsystem Vendor ID: 0x1af4 Subsystem ID: 0x1100 Revision ID: 0x0003 BSD name: en0 Kext name: AppleIntel8254XEthernet.kext Location: /System/Library/Extensions/... Version: 3.1.1b1 Ethernet still works, but it's not showing up on the PCI bus, and it no longer thinks it's plugged in to slot #2, as it used to before the change. To fix, append description for all occupied non hotpluggable PCI slots. One need to be careful when doing this: VGA devices are now described in SSDT, so we need to drop description from DSDT. And ISA devices are used in DSDT so drop them from SSDT. Reported-by: Gabriel L. Somlo <gsomlo@gmail.com> Signed-off-by: Michael S.

i440fx/acpi: do not add hotplug related amls for cold plugged bridges Cold plugged bridges are not hot unpluggable, even when their hotplug property (acpi-pci-hotplug-with-bridge-support) is turned off. Please see the function acpi_pcihp_pc_no_hotplug(). However, with the current implementaton, Windows would try to hot-unplug a pci bridge when it's hotplug switch is off. This is regardless of whether there are devices attached to the bridge. This is because we add ACPI code like _EJ0 etc for the pci slot where the bridge is cold plugged. In this fix, we identify a cold plugged bridge and for cold plugged bridges, we do not add the appropriate ACPI methods that are used by the OS to identify a hot-pluggable/unpluggable pci device. After this change, Windows does not detect the cold plugged pci bridge as ejectable.

acpi: x86: pcihp: add support hotplug on multifunction bridges Commit [1] switched PCI hotplug from native to ACPI one by default. That however breaks hotplug on following CLI that used to work: -nodefaults -machine q35 \ -device pcie-root-port,id=pcie-root-port-0,multifunction=on,bus=pcie.0,addr=0x1,chassis=1 \ -device pcie-root-port,id=pcie-root-port-1,port=0x1,addr=0x1.0x1,bus=pcie.0,chassis=2 where PCI device is hotplugged to pcie-root-port-1 with error on guest side: ACPI BIOS Error (bug): Could not resolve symbol [^S0B.PCNT], AE_NOT_FOUND (20201113/psargs-330) ACPI Error: Aborting method \_SB.PCI0.PCNT due to previous error (AE_NOT_FOUND) (20201113/psparse-531) ACPI Error: Aborting method \_GPE._E01 due to previous error (AE_NOT_FOUND) (20201113/psparse-531) ACPI Error: AE_NOT_FOUND, while evaluating GPE method [_E01] (20201113/evgpe-515) cause is that QEMU's ACPI hotplug never supported functions other then 0 and due to bug it was generating notification entries for not described functions. Technically there is no reason not to describe cold-plugged bridges (root ports) on functions other then 0, as they similarly to bridge on function 0 are unpluggable. So since we need to describe multifunction devices iterate over fuctions as well. But describe only cold-plugged bridges[root ports] on functions other than 0 as well. 1) Fixes: 17858a169508609ca9063c544833e5a1adeb7b52 (hw/acpi/ich9: Set ACPI PCI hot-plug as default on Q35) Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reported-by: Laurent Vivier <lvivier@redhat.com> Message-Id: <20210723090424.2092226-1-imammedo@redhat.com> Fixes: 17858a169508609ca9063c544833e5a1adeb7b52 (hw/acpi/ich9: Set ACPI PCI hot-plug as default on Q35)<br> Signed-off-by: Igor Mammedov &lt;<a href="mailto:imammedo@redhat.com" target="_blank">imammedo@redhat.com</a>&gt;<br> Reported-by: Laurent Vivier &lt;<a href="mailto:lvivier@redhat.com" target="_blank">lvivier@redhat.com</a>&gt;<br> Reviewed-by: Michael S.

acpi: pc: revert back to v5.2 PCI slot enumeration Commit [1] moved _SUN variable from only hot-pluggable to all devices. This made linux kernel enumerate extra slots that weren't present before. If extra slot happens to be be enumerated first and there is a device in th same slot but on other bridge, linux kernel will add -N suffix to slot name of the later, thus changing NIC name compared to QEMU 5.2. This in some case confuses systemd, if it is using SLOT NIC naming scheme and interface name becomes not the same as it was under QEMU-5.2.

Still it manages to rename virtio2 correctly to ens3, however systemd gets confused with virtio1 where slot allocation exactly the same (2-2) as in 5.2 case and tries to rename it to ens3 which is rightfully taken by virtio2) I'm not sure what breaks in systemd interface renaming (it probably should be investigated), but on QEMU side we can safely revert _SUN to 5.2 behavior (i.e. avoid cold-plugged bridges and non hot-pluggable device classes), without breaking acpi-index, which uses slot numbers but it doesn't have to use _SUN, it could use an arbitrary variable name that has the same slot value).

Still it manages to rename virtio2 correctly to ens3, however systemd gets confused with virtio1 where slot allocation exactly the same (2-2) as in 5.2 case and tries to rename it to ens3 which is rightfully taken by virtio2) I'm not sure what breaks in systemd interface renaming (it probably should be investigated), but on QEMU side we can safely revert _SUN to 5.2 behavior (i.e. avoid cold-plugged bridges and non hot-pluggable device classes), without breaking acpi-index, which uses slot numbers but it doesn't have to use _SUN, it could use an arbitrary variable name that has the same slot value). It will help existing VMs to keep networking with non trivial configs in working order since systemd will do its interface renaming magic as it used to do. 1) Fixes: b7f23f62e40 (pci: acpi: add _DSM method to PCI devices) Signed-off-by: Igor Mammedov <imammedo@redhat.com> Message-Id: <20210624204229.998824-3-imammedo@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Tested-by: John Sucaet <john.sucaet@ekinops.com> Reviewed-by: Michael S.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below. The list might include ACKs from people not holding copyright on any parts of the reused code, but it's better to err on the side of caution and include them.

pci: introduce acpi-index property for PCI device In x86/ACPI world, linux distros are using predictable network interface naming since systemd v197. Which on QEMU based VMs results into path based naming scheme, that names network interfaces based on PCI topology. With itm on has to plug NIC in exactly the same bus/slot, which was used when disk image was first provisioned/configured or one risks to loose network configuration due to NIC being renamed to actually used topology. That also restricts freedom to reshape PCI configuration of VM without need to reconfigure used guest image. systemd also offers "onboard" naming scheme which is preferred over PCI slot/topology one, provided that firmware implements: " PCI Firmware Specification 3.1 4.6.7. DSM for Naming a PCI or PCI Express Device Under Operating Systems " that allows to assign user defined index to PCI device, which systemd will use to name NIC. For example, using -device e1000,acpi-index=100 guest will rename NIC to 'eno100', where 'eno' is default prefix for "onboard" naming scheme. This doesn't require any advance configuration on guest side to com in effect at 'onboard' scheme takes priority over path based naming. Hope is that 'acpi-index' it will be easier to consume by management layer, compared to forcing specific PCI topology and/or having several disk image templates for different topologies and will help to simplify process of spawning VM from the same template without need to reconfigure guest NIC.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below. The list might include ACKs from people not holding copyright on any parts of the reused code, but it's better to err on the side of caution and include them.

acpi: build TPM Physical Presence interface The TPM Physical Presence interface consists of an ACPI part, a shared memory part, and code in the firmware. Users can send messages to the firmware by writing a code into the shared memory through invoking the ACPI code. When a reboot happens, the firmware looks for the code and acts on it by sending sequences of commands to the TPM. This patch adds the ACPI code. It is similar to the one in EDK2 but doesn't assume that SMIs are necessary to use. It uses a similar datastructure for the shared memory as EDK2 does so that EDK2 and SeaBIOS could both make use of it. I extended the shared memory data structure with an array of 256 bytes, one for each code that could be implemented. The array contains flags describing the individual codes. This decouples the ACPI implementation from the firmware implementation. The underlying TCG specification is accessible from the following page. https://trustedcomputinggroup.org/tcg-physical-presence-interface-specification/ This patch implements version 1.30.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below. The list might include ACKs from people not holding copyright on any parts of the reused code, but it's better to err on the side of caution and include them.

i386/acpi-build: more traditional _UID and _HID for PXB root buses The ACPI specification permits the _HID and _UID objects to evaluate to strings. (See "6.1.5 _HID (Hardware ID)" and "6.1.12 _UID (Unique ID)" in the ACPI v6.0 spec.) With regard to related standards, the UEFI specification can also express a device address composed from string _HID and _UID identifiers, inside the Expanded ACPI Device Path Node. (See "9.3.3 ACPI Device Path", Table 49, in the UEFI v2.5 spec.) However, numeric (integer) contents for both _HID and _UID are more traditional. They are recommended by the UEFI spec for size reasons: [...] the ACPI Device Path node is smaller and should be used if possible to reduce the size of device paths that may potentially be stored in nonvolatile storage [...] External tools support them better (for example the --acpi_hid and --acpi_uid options of "efibootmgr" only take numeric identifiers). Finally, numeric _HID and _UID contents are existing practice in the QEMU source. This patch was tested with a Fedora 20 LiveCD and a preexistent Windows Server 2012 R2 guest. Using "acpidump" and "iasl" in the Fedora guest, we get, in the SSDT: > Scope (\_SB) > { > Device (PC04) > { > Name (_UID, 0x04) // _UID: Unique ID > Name (_HID, EisaId ("PNP0A03") /* PCI Bus */) // _HID: Hardware ID Cc: Marcel Apfelbaum <marcel@redhat.com> Cc: Michael S.

hw/i386: declare ACPI mother board resource for MMCONFIG region Declare PNP0C01 device to reserve MMCONFIG region to conform to the spec better and play nice with guest BIOSes/OSes. According to PCI Firmware Specification[0], MMCONFIG region must be reserved by declaring a motherboard resource. It's optional to reserve the region in memory map by Int 15 E820h or EFIGetMemoryMap. Guest Linux checks if the MMCFG region is reserved by bios memory map or ACPI resource. If it's not reserved, Linux falls back to legacy PCI configuration access. TDVF [1] [2] doesn't reserve MMCONFIG the region in memory map. On the other hand OVMF reserves it in memory map without declaring a motherboard resource. With memory map reservation, linux guest uses MMCONFIG region. However it doesn't comply to PCI Firmware specification. [0] PCI Firmware specification Revision 3.2 4.1.2 MCFG Table Description table 4-2 NOTE 2 If the operating system does not natively comprehend reserving the MMCFG region, The MMCFG region must e reserved by firmware. ... For most systems, the mortheroard resource would appear at the root of the ACPI namespace (under \_SB)...

piix4: don't reserve hw resources when hotplug is off globally When acpi hotplug is turned off for both root pci bus as well as for pci bridges, we should not generate the related ACPI code for DSDT table or initialize related hw ports or reserve hw resources. This change makes sure all those operations are turned off in the case ACPI pci hotplug is off globally. In this change, we also make sure ACPI code for the PCNT method are only added when bsel is enabled for the corresponding pci bus or bridge hotplug is turned on. As q35 machines do not use bsel for it's pci buses at this point in time, this change affects DSDT acpi table for q35 machines as well. Therefore, we will also need to commit the updated golden master DSDT table acpi binary blobs as well. Following is the list of blobs which needs updating: tests/data/acpi/q35/DSDT tests/data/acpi/q35/DSDT.acpihmat tests/data/acpi/q35/DSDT.bridge tests/data/acpi/q35/DSDT.cphp tests/data/acpi/q35/DSDT.dimmpxm tests/data/acpi/q35/DSDT.ipmibt tests/data/acpi/q35/DSDT.memhp tests/data/acpi/q35/DSDT.mmio64 tests/data/acpi/q35/DSDT.numamem tests/data/acpi/q35/DSDT.tis These tables are updated in the following commit.

acpi-build: append description for non-hotplug As reported in http://article.gmane.org/gmane.comp.emulators.qemu/253987 Mac OSX actually requires describing all occupied slots in ACPI - even if hotplug isn't enabled. I didn't expect this so I dropped description of all non hotpluggable slots from ACPI. As a result: before commit 99fd437dee468609de8218f0eb3b16621fb6a9c9 (enable hotplug for pci bridges), PCI cards show up in the "device tree" of OS X (System Information). E.g., on MountainLion users have: Hardware -> PCI Cards: Card Type Driver Installed Slot *ethernet Ethernet Controller Yes PCI Slot 2 pci8086,2934 USB UHC Yes PCI Slot 29 ethernet: Type: Ethernet Controller Driver Installed: Yes MSI: No Bus: PCI Slot PCI Slot 2 Vendor ID: 0x8086 Device ID: 0x100e Subsystem Vendor ID: 0x1af4 Subsystem ID: 0x1100 Revision ID: 0x0003 Hardware -> Ethernet Cards ethernet: Type: Ethernet Controller Bus: PCI Slot PCI Slot 2 Vendor ID: 0x8086 Device ID: 0x100e Subsystem Vendor ID: 0x1af4 Subsystem ID: 0x1100 Revision ID: 0x0003 BSD name: en0 Kext name: AppleIntel8254XEthernet.kext Location: /System/Library/Extensions/...

acpi: build TPM Physical Presence interface The TPM Physical Presence interface consists of an ACPI part, a shared memory part, and code in the firmware. Users can send messages to the firmware by writing a code into the shared memory through invoking the ACPI code. When a reboot happens, the firmware looks for the code and acts on it by sending sequences of commands to the TPM. This patch adds the ACPI code. It is similar to the one in EDK2 but doesn't assume that SMIs are necessary to use. It uses a similar datastructure for the shared memory as EDK2 does so that EDK2 and SeaBIOS could both make use of it. I extended the shared memory data structure with an array of 256 bytes, one for each code that could be implemented. The array contains flags describing the individual codes. This decouples the ACPI implementation from the firmware implementation. The underlying TCG specification is accessible from the following page. https://trustedcomputinggroup.org/tcg-physical-presence-interface-specification/ This patch implements version 1.30.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below. The list might include ACKs from people not holding copyright on any parts of the reused code, but it's better to err on the side of caution and include them.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory.

hw/acpi/nvdimm: add a helper to augment SRAT generation NVDIMMs can belong to their own proximity domains, as described by the NFIT. In such cases, the SRAT needs to have Memory Affinity structures in the SRAT for these NVDIMMs, otherwise Linux doesn't populate node data structures properly during NUMA initialization. See the following for an example failure case. https://lore.kernel.org/linux-nvdimm/20200416225438.15208-1-vishal.l.verma@intel.com/ Introduce a new helper, nvdimm_build_srat(), and call it for both the i386 and arm versions of 'build_srat()' to augment the SRAT with memory affinity information for NVDIMMs. The relevant command line options to exercise this are below. Nodes 0-1 contain CPUs and regular memory, and nodes 2-3 are the NVDIMM address space. -object memory-backend-ram,id=mem0,size=2048M -numa node,nodeid=0,memdev=mem0, -numa cpu,node-id=0,socket-id=0 -object memory-backend-ram,id=mem1,size=2048M -numa node,nodeid=1,memdev=mem1, -numa cpu,node-id=1,socket-id=1 -numa node,nodeid=2, -object memory-backend-file,id=nvmem0,share,mem-path=nvdimm-0,size=16384M,align=1G -device nvdimm,memdev=nvmem0,id=nv0,label-size=2M,node=2 -numa node,nodeid=3, -object memory-backend-file,id=nvmem1,share,mem-path=nvdimm-1,size=16384M,align=1G -device nvdimm,memdev=nvmem1,id=nv1,label-size=2M,node=3 Cc: Jingqi Liu <jingqi.liu@intel.com> Cc: Michael S.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+.

Reason is that 2.6 kernel discards SRAT table due too small last entry which down the road leads to crashes. Hack I've tried in 10efd7e108 is also not ACPI spec compliant according to which whole possible RAM should be described in SRAT. Revert 10efd7e108 to fix regression for 2.6 based kernels. With 10efd7e108 reverted, I've also tried splitting SRAT table statically in different ways %/node and %/slot but Windows still fails to online 2nd pc-dimm hot-plugged into node 0 (as described in 10efd7e108) and sometimes even coldplugged pc-dimms where affected with static SRAT partitioning. The only known so far way where Windows stays happy is when we have 1 SRAT entry in the last node covering all hotplug area. Revert 848a1cc1e until we come up with a way to avoid regression on Windows with hotplug area split in several entries. Tested this with 2.6/3.0 based kernels (RHEL6/7) and WS20[08/12/12R2/16]).

hw/i386: AMD-Vi IVRS DMA alias support When we account for DMA aliases in the PCI address space, we can no longer use a single IVHD entry in the IVRS covering all devices. We instead need to walk the PCI bus and create alias ranges when we find a conventional bus. These alias ranges cannot overlap with a "Select All" range (as currently implemented), so we also need to enumerate each device with IVHD entries. Importantly, the IVHD entries used here include a Device ID, which is simply the PCI BDF (Bus/Device/Function). The guest firmware is responsible for programming bus numbers, so the final revision of this table depends on the update mechanism (acpi_build_update) to be called after guest PCI enumeration.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below. The list might include ACKs from people not holding copyright on any parts of the reused code, but it's better to err on the side of caution and include them.

pc: hack for migration compatibility from QEMU 2.0 Changing the ACPI table size causes migration to break, and the memory hotplug work opened our eyes on how horribly we were breaking things in 2.0 already. The ACPI table size is rounded to the next 4k, which one would think gives some headroom. In practice this is not the case, because the user can control the ACPI table size (each CPU adds 97 bytes to the SSDT and 8 to the MADT) and so some "-smp" values will break the 4k boundary and fail to migrate. Similarly, PCI bridges add ~1870 bytes to the SSDT. This patch concerns itself with fixing migration from QEMU 2.0. It computes the payload size of QEMU 2.0 and always uses that one. The previous patch shrunk the ACPI tables enough that the QEMU 2.0 size should always be enough; non-AML tables can change depending on the configuration (especially MADT, SRAT, HPET) but they remain the same between QEMU 2.0 and 2.1, so we only compute our padding based on the sizes of the SSDT and DSDT. Migration from QEMU 1.7 should work for guests that have a number of CPUs other than 12, 13, 14, 54, 55, 56, 97, 98, 139, 140. It was already broken from QEMU 1.7 to QEMU 2.0 in the same way, though. Even with this patch, QEMU 1.7 and 2.0 have two different ideas of "-M pc-i440fx-2.0" when there are PCI bridges. Igor sent a patch to adopt the QEMU 1.7 definition. I think distributions should apply it if they move directly from QEMU 1.7 to 2.1+ without ever packaging version 2.0.

Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below.

pc: hack for migration compatibility from QEMU 2.0 Changing the ACPI table size causes migration to break, and the memory hotplug work opened our eyes on how horribly we were breaking things in 2.0 already. The ACPI table size is rounded to the next 4k, which one would think gives some headroom. In practice this is not the case, because the user can control the ACPI table size (each CPU adds 97 bytes to the SSDT and 8 to the MADT) and so some "-smp" values will break the 4k boundary and fail to migrate. Similarly, PCI bridges add ~1870 bytes to the SSDT. This patch concerns itself with fixing migration from QEMU 2.0. It computes the payload size of QEMU 2.0 and always uses that one. The previous patch shrunk the ACPI tables enough that the QEMU 2.0 size should always be enough; non-AML tables can change depending on the configuration (especially MADT, SRAT, HPET) but they remain the same between QEMU 2.0 and 2.1, so we only compute our padding based on the sizes of the SSDT and DSDT. Migration from QEMU 1.7 should work for guests that have a number of CPUs other than 12, 13, 14, 54, 55, 56, 97, 98, 139, 140. It was already broken from QEMU 1.7 to QEMU 2.0 in the same way, though. Even with this patch, QEMU 1.7 and 2.0 have two different ideas of "-M pc-i440fx-2.0" when there are PCI bridges. Igor sent a patch to adopt the QEMU 1.7 definition. I think distributions should apply it if they move directly from QEMU 1.7 to 2.1+ without ever packaging version 2.0.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+.

pc: hack for migration compatibility from QEMU 2.0 Changing the ACPI table size causes migration to break, and the memory hotplug work opened our eyes on how horribly we were breaking things in 2.0 already. The ACPI table size is rounded to the next 4k, which one would think gives some headroom. In practice this is not the case, because the user can control the ACPI table size (each CPU adds 97 bytes to the SSDT and 8 to the MADT) and so some "-smp" values will break the 4k boundary and fail to migrate. Similarly, PCI bridges add ~1870 bytes to the SSDT. This patch concerns itself with fixing migration from QEMU 2.0. It computes the payload size of QEMU 2.0 and always uses that one. The previous patch shrunk the ACPI tables enough that the QEMU 2.0 size should always be enough; non-AML tables can change depending on the configuration (especially MADT, SRAT, HPET) but they remain the same between QEMU 2.0 and 2.1, so we only compute our padding based on the sizes of the SSDT and DSDT. Migration from QEMU 1.7 should work for guests that have a number of CPUs other than 12, 13, 14, 54, 55, 56, 97, 98, 139, 140. It was already broken from QEMU 1.7 to QEMU 2.0 in the same way, though. Even with this patch, QEMU 1.7 and 2.0 have two different ideas of "-M pc-i440fx-2.0" when there are PCI bridges. Igor sent a patch to adopt the QEMU 1.7 definition. I think distributions should apply it if they move directly from QEMU 1.7 to 2.1+ without ever packaging version 2.0.

* We used to align the tables to 4k, but of course this would
* too simple to be enough. 4k turned out to be too small an
* alignment very soon, and in fact it is almost impossible to
* keep the table size stable for all (max_cpus, max_memory_slots)
* combinations. So the table size is always 64k for pc-i440fx-2.1
* and we give an error if the table grows beyond that limit.
*
* We still have the problem of migrating from "-M pc-i440fx-2.0". For
* that, we exploit the fact that QEMU 2.1 generates _smaller_ tables
* than 2.0 and we can always pad the smaller tables with zeros. We can
* then use the exact size of the 2.0 tables.
*
* All this is for PIIX4, since QEMU 2.0 didn't support Q35 migration.

pc: hack for migration compatibility from QEMU 2.0 Changing the ACPI table size causes migration to break, and the memory hotplug work opened our eyes on how horribly we were breaking things in 2.0 already. The ACPI table size is rounded to the next 4k, which one would think gives some headroom. In practice this is not the case, because the user can control the ACPI table size (each CPU adds 97 bytes to the SSDT and 8 to the MADT) and so some "-smp" values will break the 4k boundary and fail to migrate. Similarly, PCI bridges add ~1870 bytes to the SSDT. This patch concerns itself with fixing migration from QEMU 2.0. It computes the payload size of QEMU 2.0 and always uses that one. The previous patch shrunk the ACPI tables enough that the QEMU 2.0 size should always be enough; non-AML tables can change depending on the configuration (especially MADT, SRAT, HPET) but they remain the same between QEMU 2.0 and 2.1, so we only compute our padding based on the sizes of the SSDT and DSDT. Migration from QEMU 1.7 should work for guests that have a number of CPUs other than 12, 13, 14, 54, 55, 56, 97, 98, 139, 140. It was already broken from QEMU 1.7 to QEMU 2.0 in the same way, though.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory.

i386: ACPI table generation code from seabios This adds C code for generating ACPI tables at runtime, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Although ACPI tables come from a system BIOS on real hw, it makes sense that the ACPI tables are coupled with the virtual machine, since they have to abstract the x86 machine to the OS's. This is widely desired as a way to avoid the churn and proliferation of QEMU-specific interfaces associated with ACPI tables in bios code. Notes: As BIOS can reprogram devices prior to loading ACPI tables, we pre-format ACPI tables but defer loading hardware configuration there until tables are loaded. The code structure was intentionally kept as close to the seabios original as possible, to simplify comparison and making sure we didn't lose anything in translation. Minor code duplication results, to help ensure there are no functional regressions, I think it's better to merge it like this and do more code changes in follow-up patches. Cross-version compatibility concerns have been addressed: ACPI tables are exposed to guest as FW_CFG entries. When running with -M 1.5 and older, this patch disables ACPI table generation, and doesn't expose ACPI tables to guest. As table content is likely to change over time, the following measures are taken to simplify cross-version migration: - All tables besides the RSDP are packed in a single FW CFG entry. This entry size is currently 23K. We round it up to 64K to avoid too much churn there. - Tables are placed in special ROM blob (not mapped into guest memory) which is automatically migrated together with the guest, same as BIOS code. - Offsets where hardware configuration is loaded in ACPI tables are also migrated, this is in case future ACPI changes make us rearrange the tables in memory. This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below.

acpi: build TPM Physical Presence interface The TPM Physical Presence interface consists of an ACPI part, a shared memory part, and code in the firmware. Users can send messages to the firmware by writing a code into the shared memory through invoking the ACPI code. When a reboot happens, the firmware looks for the code and acts on it by sending sequences of commands to the TPM. This patch adds the ACPI code. It is similar to the one in EDK2 but doesn't assume that SMIs are necessary to use. It uses a similar datastructure for the shared memory as EDK2 does so that EDK2 and SeaBIOS could both make use of it. I extended the shared memory data structure with an array of 256 bytes, one for each code that could be implemented. The array contains flags describing the individual codes. This decouples the ACPI implementation from the firmware implementation. The underlying TCG specification is accessible from the following page. https://trustedcomputinggroup.org/tcg-physical-presence-interface-specification/ This patch implements version 1.30.
