Here's couple of patches to improve the softlockup watchdog. The first changes the softlockup timer from using jiffies to sched_clock() as a timebase. Xen and VMI implement sched_clock() as counting unstolen time, so time stolen by the hypervisor won't cause the watchdog to bite. The second adds per-cpu enable flags for the watchdog timer. This allows the timer to be disabled when the

Hi, In view of the problems I was having with DomU network timeout after a live migration (I posted that problems here a while ago but never got anything except from private emails) I finally updated my Debian/Squeeze Dom0s last night to a new kernel, from 2.6.32-23 to 2.6.32-26. Now live migration just hangs...Any ideas? Xen-related Debian packages (all from Debian repositary, except drbd

The following patches are the latest update of the TSC and hrtimer patches I posted on 29/03. Rusty's original TSC patch has been resynced to the latest lguest repo, as has the hrtimer patch, which also incorporates feedback from Jeremy & Rusty: - Change clock event hrtimer to absolute time. 'now' is captured in the host during the hypercall. - Propagate -ETIME back to the

Hi Ingo, This series of patches implements a number of improvements to the softlockup watchdog and its users. They are: 1. Make the watchdog ignore stolen time When running under a hypervisor, the kernel may lose an arbitrary amount of time as "stolen time". This may cause the softlockup watchdog to trigger spruiously. Xen and VMI implement sched_clock() as measuring unstolen time,

HI: I run glusterfs with four nodes, 2x2 Distributed-Replicate. I mounted it via fuse and did some test, it was ok. However when I mounted it via nfs, a problem was found: When I copied 200G files to the glusterfs, the glusterfs process in the server node(mounted by client) was killed because of OOM, and all terminals of the client were hung. Trying to test for many times, I got the

Hi: This is a new version of trying to enable tx interrupts for virtio-net. We used to try to avoid tx interrupts and orphan packets before transmission for virtio-net. This breaks socket accounting and can lead serveral other side effects e.g: - Several other functions which depends on socket accounting can not work correctly (e.g TCP Small Queue) - No tx completion which make BQL or packet
