The ACPI specification (minimally versions 1.0b through 6.0) define the
FADT.CENTURY field as:
The RTC CMOS RAM index to the century of data value (hundred and
thousand year decimals). If this field contains a zero, then the RTC
centenary feature is not supported. If this field has a non-zero value,
then this field contains an index into RTC RAM space that OSPM can use
to program the centenary field.
The x86 targets generate ACPI payload, emulate an RTC
(CONFIG_MC146818RTC), and that RTC supports the "centenary feature" (see
occurrences of RTC_CENTURY in cmos_ioport_write() and cmos_ioport_read()
in "hw/timer/mc146818rtc.c".)
However, FADT.CENTURY is left at zero currently:
[06Ch 0108 1] RTC Century Index : 00
which -- according to analysis done by Ruiyu Ni at Intel -- should cause
Linux and Windows 8+ to think the RTC centenary feature is unavailable,
and cause Windows 7 to (incorrectly) assume that the offset to use is
constant 0x32. (0x32 happens to be the right value on QEMU, but Windows 7
is wrong to assume anything at all).
Exposing the right nonzero offset in FADT.CENTURY informs Linux and
Windows 8+ about the right capabilities of the hardware, plus it retrofits
our FADT to Windows 7's behavior.

NFIT is defined in ACPI 6.0: 5.2.25 NVDIMM Firmware Interface Table (NFIT)
Currently, we only support PMEM mode. Each device has 3 structures:
- SPA structure, defines the PMEM region info
- MEM DEV structure, it has the @handle which is used to associate specified
ACPI NVDIMM device we will introduce in later patch.
Also we can happily ignored the memory device's interleave, the real
nvdimm hardware access is hidden behind host
- DCR structure, it defines vendor ID used to associate specified vendor
nvdimm driver. Since we only implement PMEM mode this time, Command
window and Data window are not needed
The NVDIMM functionality is controlled by the parameter, 'nvdimm', which
is introduced for the machine, there is a example to enable it:
-machine pc,nvdimm -m 8G,maxmem=100G,slots=100 -object \

In 2012, QEMU had a bug where it exposed QEMU version information to the
guest, meaning a QEMU upgrade would expose different hardware to the
guest OS even if the same machine-type is being used.
The bug was fixed by commit 93bfef4c6e, on
all machines up to pc-1.0. But we kept introducing the same bug on all
newer machines since then. That means we are breaking guest ABI every
time QEMU was upgraded.
Fix this by setting the hw_version on all PC machines, making sure the
hardware won't change when upgrading QEMU.
Note that QEMU_VERSION was "1.0" in QEMU 1.0, but starting on QEMU
1.1.0, it started following the "x.y.0" pattern. We have to follow it,
to make sure we use the right QEMU_VERSION string from each QEMU
release.
The 2.5 machine classes could have hw_version unset, because the default
value for qemu_get_version() is QEMU_VERSION. But I decided to set it
explicitly to QEMU_VERSION so we don't forget to update it to "2.5.0"
after we release 2.5.0 and create a 2.6 machine class.

During reset some devices (such as hpet, rtc) might send IRQ to APIC

Fix this by resetting APIC after devices have been reset to cancel

Symptom:
$ qemu-system-x86_64 -m 10000000
Unexpected error in ram_block_add() at /work/armbru/qemu/exec.c:1456:
upstream-qemu: cannot set up guest memory 'pc.ram': Cannot allocate memory
Aborted (core dumped)
Root cause: commit ef701d7 screwed up handling of out-of-memory
conditions. Before the commit, we report the error and exit(1), in
one place, ram_block_add(). The commit lifts the error handling up
the call chain some, to three places. Fine. Except it uses
&error_abort in these places, changing the behavior from exit(1) to
abort(), and thus undoing the work of commit 3922825 "exec: Don't
abort when we can't allocate guest memory".
The three places are:
* memory_region_init_ram()
Commit 4994653 (right after commit ef701d7) lifted the error
handling further, through memory_region_init_ram(), multiplying the
incorrect use of &error_abort. Later on, imitation of existing
(bad) code may have created more.
* memory_region_init_ram_ptr()
The &error_abort is still there.
* memory_region_init_rom_device()
Doesn't need fixing, because commit 33e0eb5 (soon after commit
ef701d7) lifted the error handling further, and in the process
changed it from &error_abort to passing it up the call chain.
Correct, because the callers are realize() methods.
Fix the error handling after memory_region_init_ram() with a
Coccinelle semantic patch:
@r@
expression mr, owner, name, size, err;
position p;
@@
memory_region_init_ram(mr, owner, name, size,
(
- &error_abort
+ &error_fatal
|
err@p
)
);
@script:python@
p << r.p;
@@
print "%s:%s:%s" % (p[0].file, p[0].line, p[0].column)
When the last argument is &error_abort, it gets replaced by
&error_fatal. This is the fix.
If the last argument is anything else, its position is reported. This
lets us check the fix is complete. Four positions get reported:
* ram_backend_memory_alloc()
Error is passed up the call chain, ultimately through
user_creatable_complete(). As far as I can tell, it's callers all
handle the error sanely.
* fsl_imx25_realize(), fsl_imx31_realize(), dp8393x_realize()
DeviceClass.realize() methods, errors handled sanely further up the
call chain.
We're good. Test case again behaves:
$ qemu-system-x86_64 -m 10000000
qemu-system-x86_64: cannot set up guest memory 'pc.ram': Cannot allocate memory
[Exit 1 ]
The next commits will repair the rest of commit ef701d7's damage.

Currently IGD drivers always need to access PCH by 1f.0. But we
don't want to poke that directly to get ID, and although in real
world different GPU should have different PCH. But actually the
different PCH DIDs likely map to different PCH SKUs. We do the
same thing for the GPU. For PCH, the different SKUs are going to
be all the same silicon design and implementation, just different
features turn on and off with fuses. The SW interfaces should be
consistent across all SKUs in a given family (eg LPT). But just
same features may not be supported.
Most of these different PCH features probably don't matter to the
Gfx driver, but obviously any difference in display port connections
will so it should be fine with any PCH in case of passthrough.
So currently use one PCH version, 0x8c4e, to cover all HSW(Haswell)
scenarios, 0x9cc3 for BDW(Broadwell).

The only PC machines that didn't call pc_default_machine_options() were
isaps and xenfv. Both were already overwriting max_cpus, and only isapc
was not overwriting hot_add_cpu.

The old rules.mak loads dependency .d files using include directive
with file glob pattern "*.d". This breaks the build when build tree has
left-over *.d files from another build.
This patch fixes this by
- loading precise list of .d files made from *.o and *.mo.
- specifying explicit list of required dependency info files for
*.hex autogenerated sources.
Note that Makefile still includes some .d in root directory by including
"*.d".

In rules like "bar/%.o: %.c" there is a difference between $(*D) and
$(@D). $(*D) expands to '.', while $(@D) expands to 'bar'. It is
cleaner to generate *.d in the same directory where appropriate *.o
resides. This allows precise including of dependency info from .d files.
As a hack, we also touch two sources for generated *.hex files. Without
this hack, anyone doing "git pull; make" will not get *.hex rebuilt
correctly since the dependency file would be missing.

commit fddd179ab9,
"pc: Convert *_MACHINE_OPTIONS macros into functions"
broke the chaining of *_machine_options() functions on
pc-i440fx-2.3, at:
-#define PC_I440FX_2_3_MACHINE_OPTIONS \
- PC_I440FX_2_4_MACHINE_OPTIONS, \
- .alias = NULL, \
- .is_default = 0
+static void pc_i440fx_2_3_machine_options(QEMUMachine *m)
+{
+ pc_i440fx_machine_options(m);
+ m->alias = NULL;
+ m->is_default = 0;

I have replaced PC_I440FX_2_4_MACHINE_OPTIONS with a
pc_i440fx_machine_options() call, instead of calling
pc_i440fx_2_4_machine_options(). This broke the setting of default_machine_opts
and default_display on pc-i440fx-{2.0,2,1,2.2,2.3}.
Fix this by making pc_i440fx_2_3_machine_options() reuse
pc_i440fx_2_4_machine_options().

With the pc-q35-2.4 machine type, if the user creates an ISA FDC manually:
-device isa-fdc,driveA=drive-fdc0-0-0 \
-drive file=...,if=none,id=drive-fdc0-0-0,format=raw
then the board-default FDC will be skipped, and only the explicitly
requested FDC will exist. qtree-wise, this is correct; however such an FDC
is currently not registered in the CMOS, because that code is only reached
for the board-default FDC.
The pc_cmos_init_late() one-shot reset handler -- one-shot because the
CMOS is not reprogrammed during warm reset -- should search for any ISA
FDC devices, created implicitly (by board code) or explicitly, and set the
CMOS accordingly to the ISA FDC(s) with iobase=0x3f0:
- if there is no such FDC, report both drives absent,
- if there is exactly one such FDC, report its drives in the CMOS,
- if there are more than one such FDCs, then pick one (it is not specified
which one), and print a warning about the ambiguity.

This interface provides some registers within a 32-byte range and can be
acessed through PCI-to-LPC bridge interface (PMBASE + 0x60).
It's commonly used as a watchdog timer to detect system lockups through
SMIs that are generated -- if TCO_EN bit is set -- on every timeout. If
NO_REBOOT bit is not set in GCS (General Control and Status register),
the system will be resetted upon second timeout if TCO_RLD register
wasn't previously written to prevent timeout.
This patch adds support to TCO watchdog logic and few other features
like mapping NMIs to SMIs (NMI2SMI_EN bit), system intruder detection,
etc. are not implemented yet.

The patch
apci: fix PXB behaviour if used with unsupported BIOS
uses the following condition to see if a "PXB mem/IO chunk" has *not* been
configured by the BIOS:
(!range_base || range_base > range_limit)
When this condition evaluates to true, said patch *omits* the
corresponding entry from the _CRS.
Later on the patch checks for the opposite condition (with the intent of
*adding* entries to the _CRS if the "PXB mem/IO chunks" *have* been
configured). Unfortunately, the condition was negated incorrectly: only
the first ! operator was removed, which led to the nonsensical expression
(range_base || range_base > range_limit)
leading to bogus entries in the _CRS, and causing BSOD in Windows Server
2012 R2 when it runs on OVMF.
The correct negative of the condition seen at the top is
(range_base && range_base <= range_limit)
Fix the expressions.

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

This PIIX4 init function has no more reason to receive a pointer to the
FwCfg object. Remove the parameter from the prototype, and update callers.
As a result, the pc_init1() function no longer needs to save the return
value of pc_memory_init() and xen_load_linux(), which makes it more
similar to pc_q35_init().
The return type & value of pc_memory_init() and xen_load_linux() are not
changed themselves; maybe we'll need their return values sometime later.

Setting the parent bus of a device increases its ref count, which we
ultimately want to level out. However it is only safe to do so after the
last reference to the device in local code, as qom-set or similar operations
might decrease the ref count.
Therefore move the object_unref() from pc_new_cpu() into its callers.
The APIC operations on the last CPU in pc_cpus_init() are still potentially
insecure, but that is beyond the scope of this code movement.

The "no_floppy = 1" machine class setting causes "default_floppy" in
main() to become zero. Consequently, default_drive() will not call
drive_add() and drive_new() for IF_FLOPPY, index=0, meaning that no
default floppy drive will be created for the virtual machine. In that
case, board code should also not insist on the creation of the
board-default FDC.
The board-default FDC will still be created if the user requests a floppy
drive with "-drive if=floppy".
Additionally, separate FDCs can be specified manually with "-device
isa-fdc". They allow the
-device isa-fdc,driveA=...
syntax that is more flexible than the one required by the board-default
FDC:
-global isa-fdc.driveA=...
This patch doesn't change the behavior observably, as all Q35 machine
types have "no_floppy = 0".

This patch introduces no observable change, but it allows the callers of
pc_basic_device_init(), ie. pc_init1() and pc_q35_init(), to request (or
not request) the creation of the FDC explicitly.
At the moment both callers pass constant create_fdctrl=true (hence no
observable change).
Assuming a board passes create_fdctrl=false, "floppy" will be NULL on
output, and (beyond the FDC not being created) that NULL will be passed on
to pc_cmos_init(). Luckily, pc_cmos_init() already handles that case.

In the old times, we always had pvpanic in ACPI and a _STA method told
the guest not to use it. Automatic generation dropped the _STA method
as the specification says that missing _STA means enabled and working.
Some guests (Linux) had buggy drivers and this change made them unable
to utilize pvpanic.
A Linux patch is posted as well, but I think it's worth to make pvpanic
useable on old guests at the price of three lines and few bytes of SSDT.
The old _STA method was
Method (_STA, 0, NotSerialized) {
Store (PEST, Local0)
If (LEqual (Local0, Zero)) {
Return (Zero) }
Else {
Return (0x0F) }}
Igor pointed out that we don't need to use a method to return a constant
and that 0xB (don't show in UI) is the common definition now.
Also, the device used to be PEVT. (PEVT as in "panic event"?)

Define a MACHINE_OPTIONS macro for each PC machine, and move every field
inside the QEMUMachine structs to the macros, except for name, init, and
compat_props.
This also ensures that all MACHINE_OPTIONS inherit the fields from the
next version, so their definitions carry only the changes that exist
between one version and the next one.
Comments about specific cases:
pc-*-2.1:
Existing PC_*_2_1_MACHINE_OPTIONS macros were defined as:
PC_*_MACHINE_OPTIONS,
.default_machine_opts = "firmware=bios-256k.bin"
PC_*_2_2_MACHINE_OPTIONS is:
PC_*_2_3_MACHINE_OPTIONS
which is expanded to:
PC_*_MACHINE_OPTIONS,
.default_machine_opts = "firmware=bios-256k.bin",
.default_display = "std"
The only difference between 2_1 and 2_2 is .default_display, that's why
we didn't reuse PC_*_2_2_MACHINE_OPTIONS. The good news is that having
multiple initializers for a field is allowed by C99, and the last
initializer overrides the previous ones.
So we can reuse the 2_2 macro in 2_1 and define PC_*_2_1_MACHINE_OPTIONS
as:
PC_*_2_2_MACHINE_OPTIONS,
.default_display = NULL
pc-*-1.7:
PC_*_1_7_MACHINE_OPTIONS was defined as:
PC_*_MACHINE_OPTIONS
PC_*_2_0_MACHINE_OPTIONS is defined as:
PC_*_2_1_MACHINE_OPTIONS
which is expanded to:
PC_*_2_2_MACHINE_OPTIONS,
.default_display = NULL
which is expanded to:
PC_*_2_3_MACHINE_OPTIONS,
.default_display = NULL
which is expanded to:
PC_*_MACHINE_OPTIONS,
.default_machine_opts = "firmware=bios-256k.bin",
.default_display = "std",
.default_display = NULL /* overrides the previous line */
So, the only difference between PC_*_1_7_MACHINE_OPTIONS and
PC_*_2_0_MACHINE_OPTIONS is .default_machine_opts (as .default_display
is not explicitly set by PC_*_MACHINE_OPTIONS so it is NULL).
So we can keep the macro reuse pattern and define
PC_*_2_0_MACHINE_OPTIONS as:
PC_*_2_0_MACHINE_OPTIONS,
.default_machine_opts = NULL
pc-*-2.4 (alias and is_default fields):
Set alias and is_default fields inside the 2.4 MACHINE_OPTIONS macro,
and clear it in the 2.3 macro (that reuses the 2.4 macro).
hw_machine:
As all the machines older than v1.0 set hw_version explicitly, we can
safely move the field to the MACHINE_OPTIONS macros without affecting
the other versions that reuse them.
init function:
Some machines had the init function set inside the MACHINE_OPTIONS
macro. Move it to the QEMUMachine declaration, to keep it consistent
with the other machines.

The VGA and vmware-svga rombar compat properties were added by commit
281a26b15b, but only to pc-0.13 and
pc-0.12. This breaks the PC_COMPAT_* nesting pattern we currently
follow.
The new variables will now be inherited by pc-0.11 and older, but
pc-0.11 and pc-0.10 already have PCI.rombar=0 on compat_props, so they
shouldn't be affected at all.

The compat property was added by commit
9dbcca5aa1, and the pc-0.12 and older
machine-types were not changed because virtio-9p-pci was introduced on QEMU
0.13 (commit 9f10751365). The only problem is
that this breaks the PC_COMPAT_* nesting pattern we currently use.
So, move the property to PC_COMPAT_0_13. This make pc-0.12 and older inherit
it, but that shouldn't be an issue as QEMU 0.12 didn't have virtio-9p-pci.

Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
This reverts commit 13704e4c45.
With the Intel microcode update that removed HLE and RTM, there will be
different kinds of Haswell and Broadwell CPUs out there: some that still
have the HLE and RTM features, and some that don't have the HLE and RTM
features. On both cases people may be willing to use the pc-*-2.3
machine-types.
So instead of making the CPU model results confusing by making it depend
on the machine-type, keep HLE and RTM on the existing Haswell and
Broadwell CPU models. The plan is to introduce "Haswell-noTSX" and
"Broadwell-noTSX" CPU models later, for people who have CPUs that don't
have TSX feature available.

qemu-system-x86_64 -m 4G \
-cpu Opteron_G3,vendor=AuthenticAMD \
-smp 5,sockets=1,cores=4,threads=1,maxcpus=8 \
-numa node,nodeid=0 -numa node,nodeid=1
2.6.32 based kernels will hang on boot due to incorrectly built
sched_group-s list in update_sd_lb_stats()
Replacing default mapping with a manual, where VCPUs belonging to
the same socket are on the same NUMA node, fixes the issue for
guests which can't handle nonsense topology i.e. changing CLI to:
-numa node,nodeid=0,cpus=0-3 -numa node,nodeid=1,cpus=4-7
So instead of simply scattering VCPUs around nodes, provide
callback to map the same socket VCPUs to the same NUMA node,
which is what guests would expect from a sane hardware/BIOS.

Instead of passing icc_bridge from the PC initialization code to
cpu_x86_create(), make the PC initialization code attach the CPU to
icc_bridge.
The only difference here is that icc_bridge attachment will now be done
after x86_cpu_parse_featurestr() is called. But this shouldn't make any
difference, as property setters shouldn't depend on icc_bridge.

Older PC machine types might by accident be backwards live migration compatible,
but with the new vmdesc self-describing blob in our live migration stream we
would break that compatibility.
Also users wouldn't expect massive behaviorial differences when updating to a
new version of QEMU while retaining their old machine type, especially not
potential breakage in tooling around live migration.

Let's handle all tables in the same way: set correct size (assert if
too big), update, mark RAM dirty.
This also drops assert checking that table size didn't change: table
size is fundamentally dynamic and depends on hw configuration,
just set the correct size and use that (memory core asserts if size is
too large).
This also means we can drop tracking table size, memory core does this

monitor_handle_fd_param() is a wrapper around
monitor_handle_fd_param2() that feeds errors to qerror_report_err()
instead of returning them. qerror_report_err() is inappropriate in
many contexts. monitor_handle_fd_param() looks simpler than
monitor_handle_fd_param2(), which tempts use. Remove the temptation:
drop the wrapper and open-code the (trivial) error handling instead.
Replace the open-coded qerror_report_err() by error_report_err() in
places that already use error_report(). Turns out that's everywhere.
While there, rename monitor_handle_fd_param2() to monitor_fd_param().

Currently maxmem limit is not checked and depends on
hotplug region container not being able to fit more RAM
than maxmem. Do check explicitly so that it would

Performance wise it's better to align GVA by the backend's
page size.
Also do not allow to create DIMM device with suboptimal
size (i.e. not aligned to backends page size) to aviod
memory loss.
Do above only for 2.2 and newer machine types to avoid
breaking working configs with 2.1 machine type.

When running in KVM mode, kvm_set_phys_mem() will silently
fail if registered MemoryRegion address/size is not page
aligned. Causing memory hotplug failure in guest.
Mapping non aligned MemoryRegion in TCG mode 'works', but
sane guest OS still expects page aligned memory module
and fails to initialize it if it's not aligned.
So do not allow non aligned (i.e. valid) address/size
values for DIMM to avoid either KVM failure or guest
issues caused by it.

Nested SVM is enabled by default in the KVM kernel module, but it is

TCG doesn't support VMX, and nested VMX is not enabled by default in the
KVM kernel module.
So, there's no reason to have VMX enabled by default on the core2duo and
coreduo CPU models, today. Even the newer Intel CPU model definitions
don't have it enabled.
In this case, we need machine-type compat code, as people may be running
the older machine-types on hosts that had VMX nesting enabled.

The x86_cpu_compat_disable_kvm_features() name was a bit confusing, as
it won't forcibly disable the feature for all CPU models (i.e. add it to
kvm_default_unset_features), but it will instead turn off the KVM
auto-enabling of the feature (i.e. remove it from kvm_default_features),
meaning the feature may still be enabled by default in some CPU models).

There are three ACPI tables: 'linker_data', 'rsdp' and 'table_data'. They are
used differently. Two of them are being copied before using and only the copy
is used later. But the third is used directly. Because of that we need to free
two tables completely and delete only wrapper for the third one.

Differently from older versions, SMBIOS version 2.6 is explicit about
the encoding of UUID fields:

> consistently used little-endian byte encoding for the first three fields:

The dmidecode tool implements this and decodes the above "wire format"
when SMBIOS version >= 2.6. We moved from SMBIOS version 2.4 to 2.8 when
we started building the SMBIOS entry point inside QEMU, on commit
c97294ec1b.
Change smbios_build_type_1_table() to encode the UUID as specified.
To make sure we won't change the guest-visible UUID when upgrading to a
newer QEMU version, keep the old behavior on pc-*-2.1 and older.
