Steven,
Tracing tooling updates for 6.9
Tracing:
- Update makefiles for latency-collector and RTLA,
using tools/build/ makefiles like perf does, inheriting
its benefits. For example, having a proper way to
handle dependencies.
- The timerlat tracer has an interface for any tool to use.
rtla timerlat tool uses this interface dispatching its
own threads as workload. But, rtla timerlat could also be
used for any other process. So, add 'rtla timerlat -U'
option, allowing the timerlat tool to measure the latency of
any task using the timerlat tracer interface.
Verification:
- Update makefiles for verification/rv, using tools/build/
makefiles like perf does, inheriting its benefits.
For example, having a proper way to handle dependencies.
