Subject: [GIT PULL] tracing: Latency updates for 7.1
Date: Fri, 17 Apr 2026 05:57:41 -0400 [thread overview]
Message-ID: <20260417055741.1fc98eee@fedora> (raw)
Linus,
tracing latency updates for 7.1:
- Add TIMERLAT_ALIGN osnoise option
Add a timer alignment option for timerlat that makes it work like the
cyclictest -A option. timelat creates threads to test the latency of the
kernel. The alignment option will have these threads trigger at the
alignment offsets from each other. Instead of having each thread wake up
at the exact same time, if the alignment is set to "20" each thread will
wake up at 20 microseconds from the previous one.
Please pull the latest trace-latency-v7.1 tree, which can be found at:
