From mboxrd@z Thu Jan 1 00:00:00 1970 From: Hollis Blanchard Date: Tue, 26 Feb 2008 23:04:12 +0000 Subject: [kvm-ppc-devel] updated patches (nasty bug fixed) Message-Id: <1204067052.28836.89.camel@basalt> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: kvm-ppc@vger.kernel.org http://penguinppc.org/~hollisb/kvm/ I just fixed a nasty bug in which the changes to nonvolatile registers used in "update" form load/store MMIO instructions wouldn't be visible in the guest. This caused all sorts of nastiness, especially visible when the guest kernel timer tick code did a BUG_ON(!irqs_disabled), since the guest MSR had somehow been corrupted. Also committed various cleanups along the way, and updated to latest KVM tip. Note: I had to hack a #define KVM_PAGES_PER_HPAGE (1<<31) in order to build. Our current bug occurs when guest userspace continuously writes to the UART, which ends up "pausing" all output. Apparently UART IRQs are getting lost somewhere... -- Hollis Blanchard IBM Linux Technology Center ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
