In this version, I have integrated Aaron's changes to the amx_test. In addition, we also integrated one fix patch for a kernel warning due to xsave address issue. Patch 1: Fix a host FPU kernel warning due to missing XTILEDATA in xinit. Patch 2-8: Overhaul amx_test. These patches were basically from v2. Patch 9-13: Overhaul amx_test from Aaron. I modified the changelog a little bit. v2 -> v3: - integrate Aaron's 5 commits with minor changes on commit message. - Add one fix patch for a kernel warning. v2: https://lore.kernel.org/all/20230214184606.510551-1-mizhang@xxxxxxxxxx/ Aaron Lewis (5): KVM: selftests: x86: Assert that XTILE is XSAVE-enabled KVM: selftests: x86: Assert that both XTILE{CFG,DATA} are XSAVE-enabled KVM: selftests: x86: Remove redundant check that XSAVE is supported KVM: selftests: x86: Check that the palette table exists before using it KVM: selftests: x86: Check that XTILEDATA supports XFD Mingwei Zhang (8): x86/fpu/xstate: Avoid getting xstate address of init_fpstate if fpstate contains the component KVM: selftests: x86: Add a working xstate data structure KVM: selftests: x86: Fix an error in comment of amx_test KVM: selftests: x86: Add check of CR0.TS in the #NM handler in amx_test KVM: selftests: x86: Add the XFD check to IA32_XFD in #NM handler KVM: selftests: x86: Fix the checks to XFD_ERR using and operation KVM: selftests: x86: Enable checking on xcomp_bv in amx_test KVM: selftests: x86: Repeat the checking of xheader when IA32_XFD[XTILEDATA] is set in amx_test arch/x86/kernel/fpu/xstate.c | 10 ++- .../selftests/kvm/include/x86_64/processor.h | 14 ++++ tools/testing/selftests/kvm/x86_64/amx_test.c | 80 +++++++++---------- 3 files changed, 59 insertions(+), 45 deletions(-) -- 2.39.2.637.g21b0678d19-goog
