From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Date: Tue, 6 Dec 2011 15:03:00 +1100 From: Paul Mackerras To: Alexander Graf , Scott Wood Subject: "KVM: PPC: booke: Improve timer register emulation" breaks Book3s HV Message-ID: <20111206040300.GA12018@drongo> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Cc: linuxppc-dev@ozlabs.org, kvm-ppc@vger.kernel.org List-Id: Linux on PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , I'm not sure why yet, but commit 8a97c432 ("KVM: PPC: booke: Improve timer register emulation") in Alex's kvm-ppc-next branch is breaking Book3S HV KVM on POWER7. Guest cpus fail to spin up, and even with just one cpu, the guest stalls every so often. If I stop the guest and inspect the state with qemu, PC is at 0x900. Reverting 8a97c432 makes it work properly again. Paul.
