Message-ID: <20250721231223.465310898@kernel.org> Date: Mon, 21 Jul 2025 19:12:12 -0400 From: Steven Rostedt <rostedt@...nel.org> To: linux-kernel@...r.kernel.org Cc: Tomas Glozar <tglozar@...hat.com>, John Kacur <jkacur@...hat.com>, Luis Goncalves <lgoncalv@...hat.com>, Arnaldo Carvalho de Melo <acme@...nel.org>, Chang Yin <cyin@...hat.com>, Costa Shulyupin <costa.shul@...hat.com>, Crystal Wood <crwood@...hat.com>, Gabriele Monaco <gmonaco@...hat.com> Subject: [for-next][PATCH 8/9] rtla/tests: Limit duration to maximum of 10s From: Tomas Glozar <tglozar@...hat.com> Many of the original rtla tests included durations of 1 minute and 30 seconds. Experience has shown this is unnecessary, since 10 seconds as waiting time for samples to appear. Change duration of all rtla tests to at most 10 seconds. This speeds up testing significantly. Before: $ make check All tests successful. Files=3, Tests=54, 536 wallclock secs ( 0.03 usr 0.00 sys + 20.31 cusr 22.02 csys = 42.36 CPU) Result: PASS After: $ make check ... All tests successful. Files=3, Tests=54, 196 wallclock secs ( 0.03 usr 0.01 sys + 20.28 cusr 20.68 csys = 41.00 CPU) Result: PASS Cc: John Kacur <jkacur@...hat.com> Cc: Luis Goncalves <lgoncalv@...hat.com> Cc: Arnaldo Carvalho de Melo <acme@...nel.org> Cc: Chang Yin <cyin@...hat.com> Cc: Costa Shulyupin <costa.shul@...hat.com> Cc: Crystal Wood <crwood@...hat.com> Cc: Gabriele Monaco <gmonaco@...hat.com> Link: https://lore.kernel.org/20250626123405.1496931-9-tglozar@redhat.com Signed-off-by: Tomas Glozar <tglozar@...hat.com> Signed-off-by: Steven Rostedt (Google) <rostedt@...dmis.org> --- tools/tracing/rtla/tests/hwnoise.t | 8 ++++---- tools/tracing/rtla/tests/osnoise.t | 4 ++-- tools/tracing/rtla/tests/timerlat.t | 8 ++++---- 3 files changed, 10 insertions(+), 10 deletions(-) diff --git a/tools/tracing/rtla/tests/hwnoise.t b/tools/tracing/rtla/tests/hwnoise.t index 5f71401a139e..448877564b8d 100644 --- a/tools/tracing/rtla/tests/hwnoise.t +++ b/tools/tracing/rtla/tests/hwnoise.t @@ -10,12 +10,12 @@ check "verify help page" \ check "detect noise higher than one microsecond" \ "hwnoise -c 0 -T 1 -d 5s -q" check "set the automatic trace mode" \ - "hwnoise -a 5 -d 30s" 2 + "hwnoise -a 5 -d 10s" 2 check "set scheduling param to the osnoise tracer threads" \ - "hwnoise -P F:1 -c 0 -r 900000 -d 1M -q" + "hwnoise -P F:1 -c 0 -r 900000 -d 10s -q" check "stop the trace if a single sample is higher than 1 us" \ - "hwnoise -s 1 -T 1 -t -d 30s" 2 + "hwnoise -s 1 -T 1 -t -d 10s" 2 check "enable a trace event trigger" \ - "hwnoise -t -e osnoise:irq_noise trigger=\"hist:key=desc,duration:sort=desc,duration:vals=hitcount\" -d 1m" + "hwnoise -t -e osnoise:irq_noise trigger=\"hist:key=desc,duration:sort=desc,duration:vals=hitcount\" -d 10s" test_end diff --git a/tools/tracing/rtla/tests/osnoise.t b/tools/tracing/rtla/tests/osnoise.t index 44908fc01abf..6a4dfa31dc55 100644 --- a/tools/tracing/rtla/tests/osnoise.t +++ b/tools/tracing/rtla/tests/osnoise.t @@ -8,13 +8,13 @@ set_timeout 2m check "verify help page" \ "osnoise --help" check "verify the --priority/-P param" \ - "osnoise top -P F:1 -c 0 -r 900000 -d 1M -q" + "osnoise top -P F:1 -c 0 -r 900000 -d 10s -q" check "verify the --stop/-s param" \ "osnoise top -s 30 -T 1 -t" 2 check "verify the --trace param" \ "osnoise hist -s 30 -T 1 -t" 2 check "verify the --entries/-E param" \ - "osnoise hist -P F:1 -c 0 -r 900000 -d 1M -b 10 -E 25" + "osnoise hist -P F:1 -c 0 -r 900000 -d 10s -b 10 -E 25" # Test setting default period by putting an absurdly high period # and stopping on threshold. diff --git a/tools/tracing/rtla/tests/timerlat.t b/tools/tracing/rtla/tests/timerlat.t index b354bacd78f8..2d59ee199c4d 100644 --- a/tools/tracing/rtla/tests/timerlat.t +++ b/tools/tracing/rtla/tests/timerlat.t @@ -25,9 +25,9 @@ check "verify help page" \ check "verify -s/--stack" \ "timerlat top -s 3 -T 10 -t" 2 check "verify -P/--priority" \ - "timerlat top -P F:1 -c 0 -d 1M -q" + "timerlat top -P F:1 -c 0 -d 10s -q" check "test in nanoseconds" \ - "timerlat top -i 2 -c 0 -n -d 30s" 2 + "timerlat top -i 2 -c 0 -n -d 10s" 2 check "set the automatic trace mode" \ "timerlat top -a 5 --dump-tasks" 2 check "print the auto-analysis if hits the stop tracing condition" \ @@ -35,9 +35,9 @@ check "print the auto-analysis if hits the stop tracing condition" \ check "disable auto-analysis" \ "timerlat top -s 3 -T 10 -t --no-aa" 2 check "verify -c/--cpus" \ - "timerlat hist -c 0 -d 30s" + "timerlat hist -c 0 -d 10s" check "hist test in nanoseconds" \ - "timerlat hist -i 2 -c 0 -n -d 30s" 2 + "timerlat hist -i 2 -c 0 -n -d 10s" 2 # Actions tests check "trace output through -t" \ -- 2.47.2
