| |
Linus,
[ As the merge window opened up while I was in Prague, I almost forgot about the tooling branch (even though I was also with Daniel who did all these changes!) ]
Tracing tooling updates for 6.5:
- Add cgroup support for rtla via the -C option
- Add --house-keeping option that tells rtla where to place the housekeeping threads.
- Have rtla/timerlat have its own tracing instance instead of using the top level tracing instance that is the default for other tracing users to use.
- Add auto analysis to timerlat_hist
- Have rtla start the tracers after creating the instances
- Reduce rtla hwnoise down to 75% from 100% as it runs with preemption disabled and can cause system instability at 100%.
- Add support to run timerlat_top and timerlat_hist threads in user-space instead of just using the kernel tasks.
- Some minor clean ups and documentation changes.
