Subject: [RESEND v4 0/7] KVM: SVM: Add support for 4k vCPUs with x2AVIC
Date: Fri,  5 Sep 2025 00:03:00 +0530	[thread overview]
Message-ID: <cover.1757009416.git.naveen@kernel.org> (raw)

Nikunj pointed out that I have missed copying the x86 maintainers though 
I am adding a new CPUID feature bit. Re-sending this series for that 
reason.

--
This is v4 of the series posted here:
http://lkml.kernel.org/r/cover.1740036492.git.naveen@kernel.org

This series has been significantly re-worked based on the feedback 
received on v3, as well as to accommodate upstream changes to SVM and 
AVIC code. I have not picked up Vasant's and Pankaj's review tags for 
that purpose. Kindly review again.

Naveen N Rao (AMD) (7):
  KVM: SVM: Limit AVIC physical max index based on configured
    max_vcpu_ids
  KVM: SVM: Add a helper to look up the max physical ID for AVIC
  KVM: SVM: Replace hard-coded value 0x1FF with the corresponding macro
  KVM: SVM: Expand AVIC_PHYSICAL_MAX_INDEX_MASK to be a 12-bit field
  KVM: SVM: Move AVIC Physical ID table allocation to vcpu_precreate()
  x86/cpufeatures: Add X86_FEATURE_X2AVIC_EXT
  KVM: SVM: Add AVIC support for 4k vCPUs in x2AVIC mode
