- One-off fixes for various emulation flows (SGX, VMXON, NRIPS=0). - Reinstate IBPB on emulated VM-Exit that was incorrectly dropped a few years back when eliminating unnecessary barriers when switching between vmcs01 and vmcs02. - Clean up the MSR filter docs. - Clean up vmread_error_trampoline() to make it more obvious that params must be passed on the stack, even for x86-64. - Let userspace set all supported bits in MSR_IA32_FEAT_CTL irrespective of the current guest CPUID. - Fudge around a race with TSC refinement that results in KVM incorrectly thinking a guest needs TSC scaling when running on a CPU with a constant TSC, but no hardware-enumerated TSC frequency. -----BEGIN PGP SIGNATURE----- iQJGBAABCgAwFiEEMHr+pfEFOIzK+KY1YJEiAU0MEvkFAmOJQesSHHNlYW5qY0Bn b29nbGUuY29tAAoJEGCRIgFNDBL5IR4QAKGPbLRykY/2FohV2HDu5fDPxA2Fe9nu 5W7ZIptQu+tQtCTWKFEjcQdwYoNrLbr0hr1eGubVbIvBqJbwPQfH7G0765eOIcvy s6Zn2N24IisIoUxdkJGOL3Tt1UR7wCFbwC+ms0i4FQvMcw+TbM0BTHgJDdwR5laX mGN7ubz5iImwDFFE3Bd8Qy5I+FGL9CI60l+RzK6b7J8HYi1wOBMLU9QueF/dB7gR g+navZJAAnvN6YIkjP5j8yPBuvhDzni379ue5ATDq1ALvyyI7xlYALsxpUjCnLuo CkbvgmfmC94Vdm7pzFgsbazUN2oIjwoimjFQHP1bf8Jmd+770R282JpnwiD/ydCV Tl2ArwXA2zxVxNZm9g/XqPBwWBWWgWfYIQbuuxc065MnXCnHkY5UGGf0JNx41CDl hdtm9DHkft8+6kyBBmgkdKxd328Znljq02v3nLePUipfpDVaNj4VAUj9IpV6Lpuj GJjs4Wx7oqFwH1Im/LqZgnOGwgkSj3ObHtkYx2RSrQAQultbjuplFz2qZWP8PF6A FrJbcddKOmLINrdNOlvTd5WKCAjtV8vycjFkk+/7H67rpZdM8AI1StrzMP6gmwg4 ARozZJ2UF8nTriRYFQbFQyNm9bBTZ7YQ/HajqfhvCuZLi7i1EaImhC0F1xn7IU5S 6XhvQPvjRTgS =i6OA -----END PGP SIGNATURE----- Merge tag 'kvm-x86-fixes-6.2-1' of https://github.com/kvm-x86/linux into HEAD Misc KVM x86 fixes and cleanups for 6.2: - One-off fixes for various emulation flows (SGX, VMXON, NRIPS=0). - Reinstate IBPB on emulated VM-Exit that was incorrectly dropped a few years back when eliminating unnecessary barriers when switching between vmcs01 and vmcs02. - Clean up the MSR filter docs. - Clean up vmread_error_trampoline() to make it more obvious that params must be passed on the stack, even for x86-64. - Let userspace set all supported bits in MSR_IA32_FEAT_CTL irrespective of the current guest CPUID. - Fudge around a race with TSC refinement that results in KVM incorrectly thinking a guest needs TSC scaling when running on a CPU with a constant TSC, but no hardware-enumerated TSC frequency.
