02ff2add77 target/arm: Enable FEAT_Debugv8p8 for -cpu max
Enable FEAT_Debugv8p8 for max CPU. This feature is out of scope for QEMU
since it concerns the external debug interface for JTAG, but is
mandatory in Armv8.8 implementations, hence it is reported as supported
in the ID registers.

6c84daac58 tests/avocado: use default amount of cores on sbsa-ref
The version of the sbsa-ref EDK2 firmware we used to use in this test
had a bug where it might make an unaligned access to the framebuffer,
which causes a guest crash on newer versions of QEMU where we enforce
the architectural requirement that unaligned accesses to Device memory
should take an exception.

We happened to not notice this because our test was booting with "-smp
1" and through luck this didn't write the boot logo to the framebuffer
at an unaligned address; but trying to boot the same firmware with two
CPUs would result in a guest crash. Now we have updated the firmware
we're using for the test, we can make the test use all the cores on the
board, so we are testing the SMP boot path.

24a7cd6a7c tests/avocado: update firmware for sbsa-ref
Update firmware to have graphics card memory fix from EDK2 commit
c1d1910be6e04a8b1a73090cf2881fb698947a6e:

    OvmfPkg/QemuVideoDxe: add feature PCD to remap framebuffer W/C

    Some platforms (such as SBSA-QEMU on recent builds of the emulator) only
    tolerate misaligned accesses to normal memory, and raise alignment
    faults on such accesses to device memory, which is the default for PCIe
    MMIO BARs.

    When emulating a PCIe graphics controller, the framebuffer is typically
    exposed via a MMIO BAR, while the disposition of the region is closer to
    memory (no side effects on reads or writes, except for the changing
    picture on the screen; direct random access to any pixel in the image).

    In order to permit the use of such controllers on platforms that only
    tolerate these types of accesses for normal memory, it is necessary to
    remap the memory. Use the DXE services to set the desired capabilities
    and attributes.

    Hide this behavior under a feature PCD so only platforms that really
    need it can enable it. (OVMF on x86 has no need for this)

With this fix enabled we can boot sbsa-ref with more than one cpu core.

5d5f1b6091 hw/misc: Implement mailbox properties for customer OTP and device specific private keys
Four mailbox properties are implemented as follows:
1. Customer OTP: GET_CUSTOMER_OTP and SET_CUSTOMER_OTP
2. Device-specific private key: GET_PRIVATE_KEY and
SET_PRIVATE_KEY.

The customer OTP is located in the rows 36-43. The device-specific private key
is located in the rows 56-63.

The customer OTP can be locked with the magic numbers 0xffffffff 0xaffe0000
when running the SET_CUSTOMER_OTP mailbox command. Bit 6 of row 32 indicates
this lock, which is undocumented. The lock also applies to the device-specific
private key.

05fc711c3a target/i386: Advertise MWAIT iff host supports
host_cpu_realizefn() sets CPUID_EXT_MONITOR without consulting host/KVM
capabilities. This may cause problems:

- If MWAIT/MONITOR is not available on the host, advertising this
  feature to the guest and executing MWAIT/MONITOR from the guest
  triggers #UD and the guest doesn't boot.  This is because typically
  #UD takes priority over VM-Exit interception checks and KVM doesn't
  emulate MONITOR/MWAIT on #UD.

- If KVM doesn't support KVM_X86_DISABLE_EXITS_MWAIT, MWAIT/MONITOR
  from the guest are intercepted by KVM, which is not what cpu-pm=on
  intends to do.

In these cases, MWAIT/MONITOR should not be exposed to the guest.

The logic in kvm_arch_get_supported_cpuid() to handle CPUID_EXT_MONITOR
is correct and sufficient, and we can't set CPUID_EXT_MONITOR after
x86_cpu_filter_features().

This was not an issue before commit 662175b91f ("i386: reorder call to
cpu_exec_realizefn") because the feature added in the accel-specific
realizefn could be checked against host availability and filtered out.

Additionally, it seems not a good idea to handle guest CPUID leaves in
host_cpu_realizefn(), and this patch merges host_cpu_enable_cpu_pm()
into kvm_cpu_realizefn().

3fd73736c6 vl: Allow multiple -overcommit commands
Both cpu-pm and mem-lock are related to system resource overcommit, but
they are separate from each other, in terms of how they are realized,
and of course, they are applied to different system resources.

It's tempting to use separate command lines to specify their behavior.
e.g., in the following example, the cpu-pm command is quietly
overwritten, and it's not easy to notice it without careful inspection.

  --overcommit mem-lock=on
  --overcommit cpu-pm=on
