[PATCH RESEND 1/3] KVM: SVM: Get rid of handle_fastpath_set_msr_irqoff()

by Wanpeng Li

From: Wanpeng Li <wanpengli(a)tencent.com> Analysis from Sean: | svm->next_rip is reset in svm_vcpu_run() only after calling | svm_exit_handlers_fastpath(), which will cause SVM's | skip_emulated_instruction() to write a stale RIP. Let's get rid of handle_fastpath_set_msr_irqoff() in svm_exit_handlers_fastpath() to have a quick fix. Reported-by: Paul K. <kronenpj(a)kronenpj.dyndns.org> Suggested-by: Sean Christopherson <sean.j.christopherson(a)intel.com> Cc: Paul K. <kronenpj(a)kronenpj.dyndns.org> Cc: <stable(a)vger.kernel.org> # v5.8-rc1+ Fixes: 404d5d7bff0d (KVM: X86: Introduce more exit_fastpath_completion enum values) Signed-off-by: Wanpeng Li <wanpengli(a)tencent.com> --- arch/x86/kvm/svm/svm.c | 5 ----- 1 file changed, 5 deletions(-) diff --git a/arch/x86/kvm/svm/svm.c b/arch/x86/kvm/svm/svm.c index 19e622a..c61bc3b 100644 --- a/arch/x86/kvm/svm/svm.c +++ b/arch/x86/kvm/svm/svm.c @@ -3349,11 +3349,6 @@ static void svm_cancel_injection(struct kvm_vcpu *vcpu) static fastpath_t svm_exit_handlers_fastpath(struct kvm_vcpu *vcpu) { - if (!is_guest_mode(vcpu) && - to_svm(vcpu)->vmcb->control.exit_code == SVM_EXIT_MSR && - to_svm(vcpu)->vmcb->control.exit_info_1) - return handle_fastpath_set_msr_irqoff(vcpu); - return EXIT_FASTPATH_NONE; } -- 2.7.4

[PATCH 1/2] drm/i915/gem: Replace reloc chain with terminator on error unwind

[PATCH v2 4/7] perf/x86/amd/ibs: Don't include randomized bits in get_ibs_op_count()

by Kim Phillips

get_ibs_op_count() adds hardware's current count (IbsOpCurCnt) bits to its count regardless of hardware's valid status. According to the PPR for AMD Family 17h Model 31h B0 55803 Rev 0.54, if the counter rolls over, valid status is set, and the lower 7 bits of IbsOpCurCnt are randomized by hardware. Don't include those bits in the driver's event count.

[PATCH v2 2/7] perf/x86/amd: Fix sampling Large Increment per Cycle events

by Kim Phillips

Commit 5738891229a2 ("perf/x86/amd: Add support for Large Increment per Cycle Events") mistakenly zeroes the upper 16 bits of the count in set_period(). That's fine for counting with perf stat, but not sampling with perf record when only Large Increment events are being sampled. To enable sampling, we sign extend the upper 16 bits of the merged counter pair as described in the Family 17h PPRs: "Software wanting to preload a value to a merged counter pair writes the high-order 16-bit value to the low-order 16 bits of the odd counter and then writes the low-order 48-bit value to the even counter. Reading the even counter of the merged counter pair returns the full 64-bit value."

It depends on wha tyou want to do. I can drop this now and add both later, or just be "bug compatible" with Linus's tree until this patch gets merged into it, and then I can take it. Your call... thanks, greg k-h
