Merge tag 'trace-tools-v6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull trace tool updates from Steven Rostedt:
"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 library 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"
* tag 'trace-tools-v6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:
tools/rtla: Add -U/--user-load option to timerlat
tools/verification: Use tools/build makefiles on rv
tools/rtla: Use tools/build makefiles to build rtla
tools/tracing: Use tools/build makefiles on latency-collector

adding so the measurement for the kernel-to-user and user-to-kernel to the tracer

task that waits for a new period on the tracing/osnoise/per_cpu/cpu$ID/timerlat_fd.

# This is a sample code about how to use timerlat's timer by any workload
7
+
# so rtla can measure and provide auto-analysis for the overall latency (IOW
8

# the response time) for a task.
9
+
#
10
+
# Before running it, you need to dispatch timerlat with -U option in a terminal.
11
+
# Then # run this script pinned to a CPU on another terminal. For example:
12
+
#
13
+
# timerlat_load.py 1 -p 95
14
+
#
15
+
# The "Timerlat IRQ" is the IRQ latency, The thread latency is the latency
16
+
# for the python process to get the CPU. The Ret from user Timer Latency is
17
+
# the overall latency. In other words, it is the response time for that
18
+
# activation.
19
+
#
20

# This is just an example, the load is reading 20MB of data from /dev/full
