No changes, only added Yazen's Tested-by. Please queue, thx. Changelog: ========== v2: here's v2, dropping patch 3 and incorporating hopefully all of Radim's feedback. v1: there's this mce-inject.ko module in the kernel which allows for injecting real MCEs and thus test the MCE handling code. It is doubly useful to be able to inject same MCEs in a guest so that testing of the MCE handling code can happen even easier/faster. In order to be able to do that on an AMD guest, we need to emulate some bits and pieces like the HWCR[McStatusWrEn] bit which allows writes to the MCi_STATUS registers without a #GP. The below does that and with it I'm able to properly inject MCEs in said guest. -- Borislav Petkov (2): kvm/x86: Move MSR_K7_HWCR to svm.c x86/kvm: Implement MSR_HWCR support arch/x86/kvm/svm.c | 20 ++++++++++++++++++++ arch/x86/kvm/x86.c | 46 +++++++++++++++++++++++++++++++--------------- 2 files changed, 51 insertions(+), 15 deletions(-) -- 2.19.1
