From: Paul Mackerras <paulus@samba.org> To: kvm@vger.kernel.org, kvm-ppc@vger.kernel.org Cc: Alexander Graf <agraf@suse.de> Subject: [PATCH 0/8] PPC Book 3S HV-mode KVM updates for 3.15 Date: Tue, 25 Mar 2014 10:47:00 +1100 [thread overview] Message-ID: <1395704828-20180-1-git-send-email-paulus@samba.org> (raw) This series of patches fixes some bugs in HV-mode KVM for PowerPC Book 3S and finishes off adding the support for POWER8. Patches 2 and 3 are the two patches from the series I posted in January that Alex Graf didn't apply at that stage. I have updated them according to his review comments. The last patch is also POWER8-related, adding code to save and restore more of the host state of the PMU. (We context-switch the PMU between host and guest since the guest can access the PMU directly.) The remaining patches fix bugs that have been found over the last few months of testing. This patch series is based on the merge of the "queue" branch of the kvm tree with the "kvm-ppc-queue" branch of Alex Graf's tree, though I expect they would apply cleanly against the kvm tree "queue" branch also. I would like these to go into 3.15. Scott, please ack.
