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

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: 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

Hello: We used to orphan packets before transmission for virtio-net. This breaks socket accounting and can lead serveral functions won't work, e.g: - Byte Queue Limit depends on tx completion nofication to work. - Packet Generator depends on tx completion nofication for the last transmitted packet to complete. - TCP Small Queue depends on proper accounting of sk_wmem_alloc to work.

This series is based on v5.7-rc4. The patches are located at: https://github.com/davidhildenbrand/linux.git virtio-mem-v4 This is basically a resend of v3 [1], now based on v5.7-rc4 and restested. One patch was reshuffled and two ACKs I missed to add were added. The rebase did not require any modifications to patches. Details about virtio-mem can be found in the cover letter of v2 [2]. A
