A couple of minor improvements to the rtapp monitor:
- Making the monitor more informative to user by changing the
context of the tracepoint into the monitored task itself, not the
IPI wakeup path.
- and update the allow list regarding clock_nanosleep syscall.
- Stop monitoring the kernel threads to simplify the monitors.
- Add a new rtapp/wakeup monitor to give complement the rtapp/sleep
monitor.
v2..v1 https://lore.kernel.org/lkml/[email protected]/
- Use clearer waker/wakee terminologies
- Fix build issue
- Add new patch "rv/rtapp/sleep: Stop monitoring kernel threads"
- Require RV_PER_TASK_MONITORS >= 3
