Subject: [PATCH v2 0/3] Add KVM support for Intel local MCE
Date: Thu, 16 Jun 2016 14:05:28 +0800 [thread overview]
Message-ID: <20160616060531.30028-1-haozhong.zhang@intel.com> (raw)
Changes in v2:
* v1 Patch 1 becomes v2 Patch 3.
* Fix COB chain in Patch 3. (Boris Petkov)
* (Patch 1) Move msr_ia32_feature_control from nested_vmx to
vcpu_vmx, because it does not depend only on nested after this
patch series. (Radim Krčmář)
* (Patch 2) Add a valid bitmask for MSR_IA32_FEATURE_CONTROL to allow
checking individual bits of MSR_IA32_FEATURE_CONTROL according to
enabled features. (Radim Krčmář)
* Move the common check in handling MSR_IA32_MCG_EXT_CTL to function
vmx_mcg_ext_ctl_msr_present. (Radim Krčmář)
Changes in v1:
* Change macro KVM_MCE_CAP_SUPPORTED to variable kvm_mce_cap_supported.
* Include LMCE capability in kvm_mce_cap_supported only on Intel CPU,
i.e. LMCE can be enabled only on Intel CPU.
* Check if LMCE is enabled in guest MSR_IA32_FEATURE_CONTROL when
handling guest access to MSR_IA32_MCG_EXT_CTL.
This patch series along with the corresponding QEMU patch series (sent
via another email with title "[PATCH v4 0/3] Add QEMU support for
Intel local MCE") enables Intel local MCE feature for guest. This KVM
patch handles guest access to LMCE-related MSR (MSR_IA32_MCG_EXT_CTL
and MSR_IA32_FEATURE_CONTROL).
