Re: [uml-devel] [PATCH] um: Switch clocksource to hrtimers

I have it ported to 4.3-rc5 and the new timer API. It is about half-way through a debian dist-upgrade which was reliably crashing earlier versions. I am going to give it a spin over the weekend and if it is stable I will clean it up for submission. A. On 14/10/15 12:22, Thomas Meyer wrote:

Thomas, I need to know if you have the time-slices for this or I should take over and finish it. In addition to what Richard said I have the epoll based IRQ controller and high-performance network pipeline which depend on it in the queue. Brgds, A. On 13/10/15 22:45, Richard Weinberger

[uml-devel] [PATCH] um: Switch clocksource to hrtimers

Switch the UML clocksource from interval timers to posix interval timers and move to a monotonic timer. This fixes suspendresume related timer issues and improves network performance as TCP state machines are now fed with the correct time; also correct QoS and traffic shaping. Signed-off-by:
