Nikunj A Dadhania de0bfdc713 KVM: x86: Advertise AVX512 Bit Matrix Multiply (BMM) to userspace ... Advertise AVX512 Bit Matrix Multiply (BMM) and Bit Reversal instructions to userspace via CPUID leaf 0x80000021_EAX[23]. This feature enables bit matrix multiply operations and bit reversal. Like most AVX instructions, there are no intercept controls for individual instructions, and no extra work is needed in KVM to enable correct execution of the instructions in the guest. The instructions and CPUID feature are first described in: AMD64 Bit Matrix Multiply and Bit Reversal Instructions Publication #69192 Revision: 1.00 Issue Date: January 2026 While at it, reorder PREFETCHI in KVM's initialization sequence to match the CPUID bit position order for better organization.
