0e11fc6955 hw/i386: Replace global smp variables with machine smp properties
The global smp variables in i386 are replaced with smp machine properties.
To avoid calling qdev_get_machine() as much as possible, some related funtions
for acpi data generations are refactored. No semantic changes.

A local variable of the same name would be introduced in the declaration
phase if it's used widely in the context OR replace it on the spot if it's
only used once. No semantic changes.

a0628599fa machine: Refactor smp-related call chains to pass MachineState
To get rid of the global smp_* variables we're currently using, it's recommended
to pass MachineState in the list of incoming parameters for functions that use
global smp variables, thus some redundant parameters are dropped. It's applied
for legacy smbios_*(), *_machine_reset(), hot_add_cpu() and mips *_create_cpu().

4a4418369d q35: fix mmconfig and PCI0._CRS
This patch changes the handling of the mmconfig area.  Thanks to the
pci(e) expander devices we already have the logic to exclude address
ranges from PCI0._CRS.  We can simply add the mmconfig address range
to the list get it excluded as well.

With that in place we can go with a fixed pci hole which covers the
whole area from the end of (low) ram to the ioapic.

This will make the whole logic alot less fragile.  No matter where the
firmware places the mmconfig xbar, things should work correctly.  The
guest also gets a bit more PCI address space (seabios boot):

    # cat /proc/iomem
    [ ... ]
    7ffdd000-7fffffff : reserved
    80000000-afffffff : PCI Bus 0000:00            <<-- this is new
    b0000000-bfffffff : PCI MMCONFIG 0000 [bus 00-ff]
      b0000000-bfffffff : reserved
    c0000000-febfffff : PCI Bus 0000:00
      f8000000-fbffffff : 0000:00:01.0
    [ ... ]

So this is a guest visible change.

fe4970ad46 q35: acpi: do not create dummy MCFG table
Dummy table (with signature "QEMU") creation came from original SeaBIOS
codebase. And QEMU would have to keep it around if there were Q35 machine
that depended on keeping ACPI tables blob constant size. Luckily there
were no versioned Q35 machine types before commit:
  (since 2.3) a1666142db acpi-build: make ROMs RAM blocks resizeable
which obsoleted need to keep ACPI tables blob the same size on source/destination.

Considering the 1st versioned machine is pc-q35-2.4, the dummy table
is not really necessary and it's safe to drop it without breaking
cross version migration in both directions unconditionally.

81c48dd796 hw/i386/acpi: Add object_resolve_type_unambiguous to improve modularity
When building with CONFIG_Q35=n, we get:

    LINK    x86_64-softmmu/qemu-system-x86_64
  /usr/bin/ld: hw/i386/acpi-build.o: in function `acpi_get_misc_info':

  collect2: error: ld returned 1 exit status
  make[1]: *** [Makefile:204: qemu-system-x86_64] Error 1

This is due to a dependency in acpi-build.c on the ICH9_LPC
(via ich9_lpc_find) and PIIX4_PM (via piix4_pm_find) devices.

To allow better modularity (compile acpi-build.c with only
Q35/ICH9 or ISAPC/PIIX4), refactor the similar helper as
object_resolve_type_unambiguous(). This way we relax the
linker dependencies and can build the x86 targets with a
selection of machines (instead of all of them).

move the acpi_nvdimm_state to the generic machine struct
instead of duplicating the same code in several machines.
It is also renamed into nvdimms_state and becomes a pointer.

nvdimm and nvdimm-persistence become generic machine options.
They become guarded by a nvdimm_supported machine class member.
We also add a description for those options.

ac6dd31e3f 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.

3bb3006a63 hw: i386: Use correct RSDT length for checksum
AcpiRsdpDescriptor describes revision 2 RSDP table so using sizeof(*rsdp)
for checksum calculation isn't correct since we are adding extra 16 bytes.
But acpi_data_push() zeroes out table, so just by luck we are summing up
exta zeros which still yelds correct checksum.

Fix it up by explicitly stating table size instead of using
pointer arithmetics on stucture.

PS:
Extra 16 bytes are still wasted, but droping them will break migration
for machines older than 2.3 due to size mismatch, for 2.3 and older it's
not an issue since they are using resizable memory regions (a1666142d)
for ACPI blobs. So keep wasting memory to avoid breaking old machines.

dbb6da8ba7 pc: acpi: revert back to 1 SRAT entry for hotpluggable area
Commit
  10efd7e108 "pc: acpi: fix memory hotplug regression by reducing stub SRAT entry size"
attemped to fix hotplug regression introduced by
  848a1cc1e "hw/acpi-build: build SRAT memory affinity structures for DIMM devices"

fixed issue for Windows/3.0+ linux kernels, however it regressed 2.6 based
kernels (RHEL6) to the point where guest might crash at boot.
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]).

10efd7e108 pc: acpi: fix memory hotplug regression by reducing stub SRAT entry size
Commit 848a1cc1e (hw/acpi-build: build SRAT memory affinity structures for DIMM devices)
broke the first dimm hotplug in following cases:

 1: there is no coldplugged dimm in the last numa node
    but there is a coldplugged dimm in another node

  -m 4096,slots=4,maxmem=32G               \
  -object memory-backend-ram,id=m0,size=2G \
  -device pc-dimm,memdev=m0,node=0         \
  -numa node,nodeid=0                      \
  -numa node,nodeid=1

 2: if order of dimms on CLI is:
       1st plugged dimm in node1
       2nd plugged dimm in node0

  -m 4096,slots=4,maxmem=32G               \
  -object memory-backend-ram,size=2G,id=m0 \
  -device pc-dimm,memdev=m0,node=1         \
  -object memory-backend-ram,id=m1,size=2G \
  -device pc-dimm,memdev=m1,node=0         \
  -numa node,nodeid=0                      \
  -numa node,nodeid=1

(qemu) object_add memory-backend-ram,id=m2,size=1G
(qemu) device_add pc-dimm,memdev=m2,node=0

the first DIMM hotplug to any node except the last one
fails (Windows is unable to online it).

Length reduction of stub hotplug memory SRAT entry,
fixes issue for some reason.

16b4226363 hw/acpi-build: Add a check for memory-less NUMA nodes
Currently, Qemu ACPI builder doesn't consider the memory-less NUMA nodes, eg:

  -m 4G,slots=4,maxmem=8G \
  -numa node,nodeid=0 \
  -numa node,nodeid=1,mem=2G \
  -numa node,nodeid=2,mem=2G \
  -numa node,nodeid=3\

Guest Linux will report

  [    0.000000] ACPI: SRAT: Node 0 PXM 0 [mem 0x00000000-0xffffffffffffffff]
  [    0.000000] ACPI: SRAT: Node 1 PXM 1 [mem 0x00000000-0x0009ffff]
  [    0.000000] ACPI: SRAT: Node 1 PXM 1 [mem 0x00100000-0x7fffffff]
  [    0.000000] ACPI: SRAT: Node 2 PXM 2 [mem 0x80000000-0xbfffffff]
  [    0.000000] ACPI: SRAT: Node 2 PXM 2 [mem 0x100000000-0x13fffffff]
  [    0.000000] ACPI: SRAT: Node 3 PXM 3 [mem 0x140000000-0x13fffffff]
  [    0.000000] ACPI: SRAT: Node 3 PXM 3 [mem 0x140000000-0x33fffffff] hotplug

[mem 0x00000000-0xffffffffffffffff] and [mem 0x140000000-0x13fffffff] are bogus.

b0c14ec4ef machine: make MemoryHotplugState accessible via the machine
Let's allow to query the MemoryHotplugState directly from the machine.
If the pointer is NULL, the machine does not support memory devices. If
the pointer is !NULL, the machine supports memory devices and the
data structure contains information about the applicable physical
guest address space region.

This allows us to generically detect if a certain machine has support
for memory devices, and to generically manage it (find free address
range, plug/unplug a memory region).

We will rename "MemoryHotplugState" to something more meaningful
("DeviceMemory") after we completed factoring out the pc-dimm code into
MemoryDevice code.

2cc0e2e814 pc-dimm: factor out MemoryDevice interface
On the qmp level, we already have the concept of memory devices:
    "query-memory-devices"
Right now, we only support NVDIMM and PCDIMM.

We want to map other devices later into the address space of the guest.
Such device could e.g. be virtio devices. These devices will have a
guest memory range assigned but won't be exposed via e.g. ACPI. We want
to make them look like memory device, but not glued to pc-dimm.

Especially, it will not always be possible to have TYPE_PC_DIMM as a parent
class (e.g. virtio devices). Let's use an interface instead. As a first
part, convert handling of
- qmp_pc_dimm_device_list
- get_plugged_memory_size
to our new model. plug/unplug stuff etc. will follow later.

A memory device will have to provide the following functions:
- get_addr(): Necessary, as the property "addr" can e.g. not be used for
              virtio devices (already defined).
- get_plugged_size(): The amount this device offers to the guest as of
                      now.
- get_region_size(): Because this can later on be bigger than the
                     plugged size.
- fill_device_info(): Fill MemoryDeviceInfo, e.g. for qmp.

cb3e7f08ae qobject: Replace qobject_incref/QINCREF qobject_decref/QDECREF
Now that we can safely call QOBJECT() on QObject * as well as its
subtypes, we can have macros qobject_ref() / qobject_unref() that work
everywhere instead of having to use QINCREF() / QDECREF() for QObject
and qobject_incref() / qobject_decref() for its subtypes.

The replacement is mechanical, except I broke a long line, and added a
cast in monitor_qmp_cleanup_req_queue_locked().  Unlike
qobject_decref(), qobject_unref() doesn't accept void *.

Note that the new macros evaluate their argument exactly once, thus no
need to shout them.

848a1cc1e8 hw/acpi-build: build SRAT memory affinity structures for DIMM devices
ACPI 6.2A Table 5-129 "SPA Range Structure" requires the proximity
domain of a NVDIMM SPA range must match with corresponding entry in
SRAT table.

The address ranges of vNVDIMM in QEMU are allocated from the
hot-pluggable address space, which is entirely covered by one SRAT
memory affinity structure. However, users can set the vNVDIMM
proximity domain in NFIT SPA range structure by the 'node' property of
'-device nvdimm' to a value different than the one in the above SRAT
memory affinity structure.

In order to solve such proximity domain mismatch, this patch builds
one SRAT memory affinity structure for each DIMM device present at
boot time, including both PC-DIMM and NVDIMM, with the proximity
domain specified in '-device pc-dimm' or '-device nvdimm'.

The remaining hot-pluggable address space is covered by one or multiple
SRAT memory affinity structures with the proximity domain of the last
node as before.

because we include those wherever the macros get used.

Open-coding these helpers is of dubious value.  Turn them into
functions and drop the includes from the headers.

This cleanup makes the number of objects depending on qapi/qmp/qnum.h
from 4551 (out of 4743) to 46 in my "build everything" tree.  For

4ab6cb4c62 tpm: add CRB device
tpm_crb is a device for TPM 2.0 Command Response Buffer (CRB)
Interface as defined in TCG PC Client Platform TPM Profile (PTP)
Specification Family “2.0” Level 00 Revision 01.03 v22.

The PTP allows device implementation to switch between TIS and CRB
model at run time, but given that CRB is a simpler device to
implement, I chose to implement it as a different device.

The device doesn't implement other locality than 0 for now (my laptop
TPM doesn't either, so I assume this isn't so bad)

Tested with some success with Linux upstream and Windows 10, seabios &
modified ovmf. The device is recognized and correctly transmit
command/response with passthrough & emu. However, we are missing PPI
ACPI part atm.

37f51384ae intel-iommu: Extend address width to 48 bits
The current implementation of Intel IOMMU code only supports 39 bits
iova address width. This patch provides a new parameter (x-aw-bits)
for intel-iommu to extend its address width to 48 bits but keeping the
default the same (39 bits). The reason for not changing the default
is to avoid potential compatibility problems with live migration of
intel-iommu enabled QEMU guest. The only valid values for 'x-aw-bits'
parameter are 39 and 48.

After enabling larger address width (48), we should be able to map
larger iova addresses in the guest. For example, a QEMU guest that
is configured with large memory ( >=1TB ). To check whether 48 bits
aw is enabled, we can grep in the guest dmesg output with line:
"DMAR: Host address width 48".

ff5ce21e1b acpi: change TPM TIS data conditions
The device should be exposed if present. It shouldn't have an
undefined version (or else backend init failed, and device should fail
too). Finally, make the fields specific to TIS device model.

5f9252f7cc fw_cfg: add write callback
Reintroduce the write callback that was removed when write support was
removed in commit 023e314856.

Contrary to the previous callback implementation, the write_cb
callback is called whenever a write happened, so handlers must be
ready to handle partial write as necessary.
