32a2d6b1f6 hw/i386/amd_iommu.c: Fix corruption of log events passed to guest
In the function amdvi_log_event(), we write an event log buffer
entry into guest ram, whose contents are passed to the function
via the "uint64_t *evt" argument. Unfortunately, a spurious
'&' in the call to dma_memory_write() meant that instead of
writing the event to the guest we would write the literal value
of the pointer, plus whatever was in the following 8 bytes
on the stack. This error was spotted by Coverity.

Fix the bug by removing the '&'.

f7795e4096 misc: Replace zero-length arrays with flexible array member (automatic)
Description copied from Linux kernel commit from Gustavo A. R. Silva
(see [3]):

--v-- description start --v--

  The current codebase makes use of the zero-length array language
  extension to the C90 standard, but the preferred mechanism to
  declare variable-length types such as these ones is a flexible
  array member [1], introduced in C99:

  struct foo {
      int stuff;
      struct boo array[];
  };

  By making use of the mechanism above, we will get a compiler
  warning in case the flexible array does not occur last in the
  structure, which will help us prevent some kind of undefined
  behavior bugs from being unadvertenly introduced [2] to the
  Linux codebase from now on.

--^-- description end --^--

Do the similar housekeeping in the QEMU codebase (which uses
C99 since commit 7be41675f7).

All these instances of code were found with the help of the
following Coccinelle script:

  @@
  identifier s, m, a;
  type t, T;
  @@
   struct s {
      ...
      t m;
  -   T a[0];
  +   T a[];
  };
  @@
  identifier s, m, a;
  type t, T;

   struct s {

a6f65f4fc2 hw/i386/intel_iommu: Simplify vtd_find_as_from_bus_num() logic
The vtd_find_as_from_bus_num() function was introduced (in commit
dbaabb25f) in a code format that could return an incorrect pointer,
which was later fixed by commit a2e1cd41cc.
We could have avoided this by writing the if() statement differently.
Do it now, in case this function is re-used. The code is easier to
review (harder to miss bugs).

bb38df846d hw/i386/vmmouse: Fix crash when using the vmmouse on a machine without vmport
QEMU currently crashes when the user tries to use the "vmmouse" on a
machine without vmport, e.g.:

 $ x86_64-softmmu/qemu-system-x86_64 -machine microvm -device vmmouse
 Segmentation fault (core dumped)

or:

 $ x86_64-softmmu/qemu-system-x86_64 -device vmmouse -M pc,vmport=off
 Segmentation fault (core dumped)

Let's avoid the crash by checking for the vmport device first.

f703a04ce5 add device_legacy_reset function to prepare for reset api change
Provide a temporary device_legacy_reset function doing what
device_reset does to prepare for the transition with Resettable
API.

All occurrence of device_reset in the code tree are also replaced
by device_legacy_reset.

The new resettable API has different prototype and semantics
(resetting child buses as well as the specified device). Subsequent
commits will make the changeover for each call site individually; once
that is complete device_legacy_reset() will be removed.

6cdda0ff4b hw/core/loader: Let load_elf() populate a field with CPU-specific flags
While loading the executable, some platforms (like AVR) need to
detect CPU type that executable is built for - and, with this patch,
this is enabled by reading the field 'e_flags' of the ELF header of
the executable in question. The change expands functionality of
the following functions:

  - load_elf()
  - load_elf_as()
  - load_elf_ram()
  - load_elf_ram_sym()

The argument added to these functions is called 'pflags' and is of
type 'uint32_t*' (that matches 'pointer to 'elf_word'', 'elf_word'
being the type of the field 'e_flags', in both 32-bit and 64-bit
variants of ELF header). Callers are allowed to pass NULL as that
argument, and in such case no lookup to the field 'e_flags' will
happen, and no information will be returned, of course.

aefcaf9d1b i386:acpi: Remove _HID from the SMBus ACPI entry
Per the ACPI spec (version 6.1, section 6.1.5 _HID) it is not required
on enumerated buses (like PCI in this case), _ADR is required (and is
already there).  And the _HID value is wrong.  Linux appears to ignore
the _HID entry, but Windows 10 detects it as 'Unknown Device' and there
is no driver available.  See https://bugs.launchpad.net/qemu/+bug/1856724

f404220e27 q35: implement 128K SMRAM at default SMBASE address
It's not what real HW does, implementing which would be overkill [**]
and would require complex cross stack changes (QEMU+firmware) to make
it work.
So considering that SMRAM is owned by MCH, for simplicity (ab)use
reserved Q35 register, which allows QEMU and firmware easily init
and make RAM at SMBASE available only from SMM context.

Patch uses commit (2f295167e0 q35/mch: implement extended TSEG sizes)
for inspiration and uses reserved register in config space at 0x9c
offset [*] to extend q35 pci-host with ability to use 128K at
0x30000 as SMRAM and hide it (like TSEG) from non-SMM context.

Usage:
  1: write 0xff in the register
  2: if the feature is supported, follow up read from the register
     should return 0x01. At this point RAM at 0x30000 is still
     available for SMI handler configuration from non-SMM context
  3: writing 0x02 in the register, locks SMBASE area, making its contents
     available only from SMM context. In non-SMM context, reads return
     0xff and writes are ignored. Further writes into the register are
     ignored until the system reset.

1bbd1511b6 Clean-ups: qom-ify serial and remove QDEV_PROP_PTR
Hi,
 
 QDEV_PROP_PTR is marked in multiple places as "FIXME/TODO/remove
 me". In most cases, it can be easily replaced with QDEV_PROP_LINK when
 the pointer points to an Object.
 
 There are a few places where such substitution isn't possible. For
 those places, it seems reasonable to use a specific setter method
 instead, and keep the user_creatable = false. In other places,
 proper usage of qdev or other facilies is the solution.
 
 The serial code wasn't converted to qdev, which makes it a bit more
 archaic to deal with. Let's convert it first, so we can more easily
 embed it from other devices, and re-export some properties and drop
 QDEV_PROP_PTR usage.

ff2efdcdc1 hw/i386/Kconfig: Let the MicroVM machine select the SERIAL_ISA config
When configured with --without-default-devices, the build fails:

  /usr/bin/ld: hw/i386/microvm.o: in function `microvm_devices_init':

While the MicroVM machine only uses the ISA serial port when the
MICROVM_MACHINE_ISA_SERIAL property is set, it has to be linked
with it. Replace the 'imply' Kconfig rule by a 'select'.

a88c40f02a hw/i386/pc: fix regression in parsing vga cmdline parameter
When the 'vga=' parameter is succeeded by another parameter, QEMU 4.2.0
would refuse to start with a rather cryptic message:

    $ qemu-system-x86_64 -kernel /boot/vmlinuz-linux -append 'vga=792 quiet'
    qemu: can't parse 'vga' parameter: Invalid argument

It was not clear whether this applied to the '-vga std' parameter or the
'-append' one. Fix the parsing regression and clarify the error.

5.0 machine type uses 4.2 compats. This seems to be incorrect, since
the latests machine type by now is 5.0 and it should use its own
compat or shouldn't use any relying on the defaults.
Seems, like this appeared because of some problems on merge/rebase.

e6f123c3b8 hmat acpi: Build Memory Proximity Domain Attributes Structure(s)
HMAT is defined in ACPI 6.3: 5.2.27 Heterogeneous Memory Attribute Table
(HMAT). The specification references below link:
http://www.uefi.org/sites/default/files/resources/ACPI_6_3_final_Jan30.pdf

It describes the memory attributes, such as memory side cache
attributes and bandwidth and latency details, related to the
Memory Proximity Domain. The software is
expected to use this information as hint for optimization.

This structure describes Memory Proximity Domain Attributes by memory
subsystem and its associativity with processor proximity domain as well as
hint for memory usage.

In the linux kernel, the codes in drivers/acpi/hmat/hmat.c parse and report
the platform's HMAT tables.

that the first 12 bits are omitted. This causes the guest

30d2a17b46 hw/i386: Remove the deprecated machines 0.12 up to 0.15
These machines can't be used reliably for migration anymore, quoting
https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg04516.html :

"
 due to the introduction of the memory API, the firmware is not
 migrated correctly from source to destination.  On QEMU <1.3 the
 0xf0000-0xfffff area is basically a copy of the higher
 0xffff0000-0xffffffff area, while on more recent versions it is
 initialized with zeroes and the firmware copies from 0xffff0000 to
 0xf0000.  When you migrate from old to new QEMU, after reboot there's
 nothing at 0xf0000 and bugs ensue.
"

The pc-0.x machines have been marked as deprecated since QEMU v4.0, so
it is time to remove them now.

And while we're at it, mark the remaining pc-1.x machine types
as deprecated now, too, so that we finally only have "pc-i440fx"
and "pc-q35" machine types left (apart from the non-versioned
"isapc" and "microvm") once we remove them in a couple of releases.
