From 04f837165b9480d6d6d8b00bbc1298762f3f0e4d Mon Sep 17 00:00:00 2001 From: Tomas Glozar Date: Thu, 26 Jun 2025 14:34:04 +0200 Subject: [PATCH] rtla/tests: Limit duration to maximum of 10s 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 Cc: Luis Goncalves Cc: Arnaldo Carvalho de Melo Cc: Chang Yin Cc: Costa Shulyupin Cc: Crystal Wood Cc: Gabriele Monaco Link: https://lore.kernel.org/20250626123405.1496931-9-tglozar@redhat.com Signed-off-by: Tomas Glozar Signed-off-by: Steven Rostedt (Google) --- 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 5f71401a139e6..448877564b8d9 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 44908fc01abfd..6a4dfa31dc55e 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 b354bacd78f85..2d59ee199c4da 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
