[kvm-unit-tests GIT PULL] x86: random smattering of changes

[Sean Christopherson]

Please pull a rather random set of changes that have been accumulating over
the last few months.

Note, the SKINIT nSVM intercept test fails on some Turin CPUs, but allegedly
only on pre-production hardware?  I assume/hope such hardware isn't commonly
available, and so didn't bother trying to handle it in upstream KUT.

The following changes since commit 9eb6c57313060d34f7e5b2ac6f90bb5873bbe2ff:

  Merge branch 'mbec' into HEAD (2026-05-12 13:03:25 +0200)

are available in the Git repository at:

  x86/vmx: Remove the superfluous vmx_cet config entry (2026-05-27 08:59:46 -0700)

----------------------------------------------------------------
KVM-Unit-Tests x86 changes:

 - Track SVM's EXIT_CODE as a 64-bit value, to verify KVM does the same.

 - Add nSVM tests for unsupported instruction intercepts.

 - Serialize the (v)CPU after WRMSR(TSCDEADLINE) to prepare for APIC timer
   virtualization.

 - Disable PKU in the vCPU model when running the nVMX access tests to make
   the runtime somewhat reasonable.

 - Extended the VMOVDQA test to cover VMOVNTDQA as well.

 - Add test coverage for ENTER + emulated MMIO.

 - Misc fixes, cleanups, and minor coverage enhancements.

----------------------------------------------------------------
Isaku Yamahata (2):
      x86: Replace NOP with CPUID after WRMSR(TSCDEADLINE) to serialize deadline timer
      x86: tscdeadline_latency: Remove unnecessary nop

Maxim Levitsky (1):
      Skip PMU portion of vmware_backdoors test if PMU is not enabled.

Sean Christopherson (9):
      x86/cstart: Delete "local" version of save_id() to fix x2APIC SMP bug

Because I hate bumping the timeouts.  It's a losing game of whack-a-mole.  For
now, it's easier to bury my head in the sand.

We're already doing this for vmx:
https://gitlab.com/kvm-unit-tests/kvm-unit-tests/-/blob/master/x86/vmx_tests.c?ref_type=heads#L806.

If this is the only thing holding that series, I think cleaning it up
should be done separately for both VMX and SVM.

I don't buy that argument.  Taking it to the extreme, that's like saying it's ok
to use bare "unsigned" because there exists such code in the kernel.  It's very
difficult to make progress if we don't raise the bar.

I'm not saying "no" to the series, nor am saying you (or Kevin) needs to clean
up the nVMX code in order to land the nSVM code.  I'm simply explaining why I
didn't grab the series: it's got some fugly code I want to look at more closely,
but I ran out of time and brainpower.

That's fair.

Understandable, sorry if I came off too pushy. Thank you for taking
the time to shepherd x86 KUT changes.

Pulled, thanks.

(I haven't pushed my 32-bit tests yet, especially since you preferred to 
leave out the new nSVM test).

>    x86/vmx: Remove the superfluous vmx_cet config entry (2026-05-27 08:59:46 -0700)
> 
> ----------------------------------------------------------------
> KVM-Unit-Tests x86 changes:
> 
>   - Track SVM's EXIT_CODE as a 64-bit value, to verify KVM does the same.
> 
>   - Add nSVM tests for unsupported instruction intercepts.
> 
>   - Serialize the (v)CPU after WRMSR(TSCDEADLINE) to prepare for APIC timer
>     virtualization.
> 
>   - Disable PKU in the vCPU model when running the nVMX access tests to make
>     the runtime somewhat reasonable.
> 
>   - Extended the VMOVDQA test to cover VMOVNTDQA as well.
> 
>   - Add test coverage for ENTER + emulated MMIO.
> 
>   - Misc fixes, cleanups, and minor coverage enhancements.
