From: Tom Lendacky <thomas.lendacky@amd.com> This patch series provides fixes in the area of ASID assignment and VM deactivation. Additionally, it provides some performance enhancements by reducing the number of WBINVD/DF_FLUSH invocations that are made. Note: The third patch in the series modifies a file that is outside of the arch/x86/kvm directory. --- Patches based on https://git.kernel.org/pub/scm/virt/kvm/kvm.git next and commit: fd3edd4a9066 ("KVM: nVMX: cleanup and fix host 64-bit mode checks") Tom Lendacky (5): KVM: SVM: Serialize access to the SEV ASID bitmap KVM: SVM: Guard against DEACTIVATE when performing WBINVD/DF_FLUSH KVM: SVM: Remove unneeded WBINVD and DF_FLUSH when starting SEV guests KVM: SVM: Convert DEACTIVATE mutex to read/write semaphore KVM: SVM: Reduce WBINVD/DF_FLUSH invocations arch/x86/kvm/svm.c | 105 +++++++++++++++++++++++++++-------- drivers/crypto/ccp/psp-dev.c | 9 +++ 2 files changed, 92 insertions(+), 22 deletions(-)
