| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allowing a guest to execute MWAIT without interception enables a guest to put a (physical) CPU into a power saving state, where it takes longer to return from than what may be desired by the host. Don't give a guest that power over a host by default. (Especially, since nothing prevents a guest from using MWAIT even when it is not advertised via CPUID.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The changes in the 3214d01f139b ("KVM: PPC: Book3S: Provide information about hardware/firmware CVE workarounds") commit right now will not produce any change in the tools, but that is because we still need to improve tools/perf/trace/beauty/kvm_ioctl.sh to build per arch string tables, so that we avoid assigning multiple times to the same command string entry, i.e. multiple defines, for different arches, have the same value, causing this: In file included from trace/beauty/ioctl.c:82:0: /tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c: In function ‘ioctl__scnprintf_kvm_cmd’: /tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c:76:11: error: initialized field overwritten [-Werror=override-init] /tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c:88:11: note: (near initialization for ‘kvm_ioctl_cmds[165]’) /tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c:90:11: error: initialized field overwritten [-Werror=override-init] [0xa6] = "PPC_GET_SMMU_INFO", ^~~~~~~~~~~~~~~~~~~ So the onlye effect of updating the tools/ copy of ppc's kvm.h header is to silence these perf build warnings: Warning: Kernel ABI header at 'tools/include/uapi/linux/kvm.h' differs from latest version at 'include/uapi/linux/kvm.h' Warning: Kernel ABI header at 'tools/arch/powerpc/include/uapi/asm/kvm.h' differs from latest version at 'arch/powerpc/include/uapi/asm/kvm.h' At some point we should do what we did for the errno tables and create per-arch string translation tables for the KVM ioctl commands for the architectures supporting KVM, such as s/390, PowerPC, x86_64 and ARM.
