litmus-rt-ext-res.git/kernel, branch EXT-RES

Changed Ordering of sched classes to stop->dl->rt->litmus->fair->idle

Core: call IPI notifier from generic scheduler IPI handler

2017-06-15T08:02:16+00:00

Instead of replicating this code across all supported architectures,
hook into the IPI code only once.

LITMUS^RT integration in core scheduler: include debug_trace.h

Hook into hrtimer to TRACE() timer hangs

2017-05-26T21:12:39+00:00

Hook into hrtimer_nanosleep()

2017-05-26T21:12:39+00:00

To intercept absolute-timed nanosleeps relative to CLOCK_MONOTONIC,
which are likely related to periodic job arrivals.

hrtimer integration: properly trace late-added timers

2017-05-26T21:12:39+00:00

When tasks add timers that have already expired (e.g., when preempted
during schedule_hrtimeout), we should not use the expriration time as
the reference time point, but rather the time when the timer was added
(the delay then includes activation of ksoftirqd, etc.).

Hook into hrtimer to report large latencies

2017-05-26T21:12:38+00:00

Patch hrtimer_wakeup() callback to record RELEASE overhead

2017-05-26T21:12:38+00:00

Patch hrtimer_wakeup() callback to record RELEASE_LATENCY

2017-05-26T21:12:37+00:00

Record interrupt latency for tasks that use nanosleep or some other
interface that ends up using a hrtimer_sleeper struct to trigger the
wakeup of the task when the next job is released.

Hook into kernel/exit.c to force exiting RT tasks into best-effort mode
