From mboxrd@z Thu Jan 1 00:00:00 1970 From: Liang Chen Subject: [PATCH v3 0/2] KVM: count actual tlb flushes Date: Thu, 18 Sep 2014 12:38:35 -0400 Message-ID: <1411058317-23646-1-git-send-email-liangchen.linux@gmail.com> Mime-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: QUOTED-PRINTABLE Cc: rkrcmar@redhat.com, kvm@vger.kernel.org, linux-kernel@vger.kernel.org, Liang Chen To: pbonzini@redhat.com Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: kvm.vger.kernel.org * Instead of counting the number of coalesced flush requests, we count the actual tlb flushes. * Flushes from kvm_flush_remote_tlbs will also be counted. * Freeing the namespace a bit by replaces kvm_mmu_flush_tlb() with kvm_make_request() again. --- v2 -> v3: * split the patch into a series of two patches. * rename the util function kvm_mmu_flush_tlb in x86.c to kvm_vcpu_flush_tlb v1 -> v2: * Instead of calling kvm_mmu_flush_tlb everywhere to make sure the stat is always incremented, postponing the counting to kvm_check_request.
