-Subject: KVM: x86: obey KVM_X86_QUIRK_CD_NW_CLEARED in kvm_set_cr0()
-
-Commit b18d5431acc7 ("KVM: x86: fix CR0.CD virtualization") was
-technically correct, but it broke OVMF guests by slowing down various
-parts of the firmware.
-
-Commit fb279950ba02 ("KVM: vmx: obey KVM_QUIRK_CD_NW_CLEARED") quirked the
-first function modified by b18d5431acc7, vmx_get_mt_mask(), for OVMF's
-sake. This restored the speed of the OVMF code that runs before
-PlatformPei (including the memory intensive LZMA decompression in SEC).
-
-This patch extends the quirk to the second function modified by
-b18d5431acc7, kvm_set_cr0(). It eliminates the intrusive slowdown that
-hits the EFI_MP_SERVICES_PROTOCOL implementation of edk2's
-UefiCpuPkg/CpuDxe -- which is built into OVMF --, when CpuDxe starts up
-all APs at once for initialization, in order to count them.
-
-We also carry over the kvm_arch_has_noncoherent_dma() sub-condition from
-the other half of the original commit b18d5431acc7.
-
-Fixes: b18d5431acc7a2fd22767925f3a6f597aa4bd29e
