torture: Check for "Call trace:" as well as "Call Trace:"

2025-05-16T15:14:00Z

Different architectures capitalize their splats differently. Who knew? This commit therefore checks for both arm64 "Call trace:" and x86 "Call Trace:".

rcutorture: Copy out ftrace into its own console file

2023-09-24T15:24:01Z

When debugging, it can be difficult to quickly find the ftrace dump within the console log, which in turn makes it difficult to process it independent of the rest of the console output. This commit therefore copies the contents of the buffers into its own file to make it easier to locate and process the ftrace dump. The original ftrace dump is still available in the console log in cases because it can be more convenient to process it in situ, for example, for scripts that process console output as well as ftrace-dump data. Also handle the case of multiple ftrace dumps potentially showing up in the log. Example for a file like [1], it will extract as [2]. [1]: foo foo Dumping ftrace buffer: --------------------------------- blah blah --------------------------------- more bar baz Dumping ftrace buffer: --------------------------------- blah2 blah2 --------------------------------- bleh bleh [2]: Ftrace dump 1: blah blah Ftrace dump 2: blah2 blah2 [ paulmck: Fixed awk indentation, input up front. ] Signed-off-by: Joel Fernandes (Google) Signed-off-by: Paul E.

selftests: rcutorture: Use "grep -E" instead of "egrep"

2023-01-04T01:53:31Z

The latest version of grep is deprecating the egrep command, so that its output contains warnings as follows: egrep: warning: egrep is obsolescent; using grep -E Fix this using "grep -E" instead. sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/testing/selftests/rcutorture` Here are the steps to install the latest grep: wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz tar xf grep-3.8.tar.gz cd grep-3.8 && ./configure && make sudo make install export PATH=/usr/local/bin:$PATH Signed-off-by: Tiezhu Yang Signed-off-by: Paul E.

torture: Make kvm.sh summaries note runs having only KCSAN reports

2022-02-02T01:25:41Z

Runs having only KCSAN reports will normally print a summary line containing only a "Bugs:" entry. However, these bugs might or might not be KCSAN reports. This commit therefore flags runs in which all the "Bugs:" entries are KCSAN reports. Signed-off-by: Paul E. McKenney

torture: Remove "Failed to add ttynull console" false positive

2021-01-04T22:01:25Z

Commit 757055ae8ded ("init/console: Use ttynull as a fallback when there is no console") results in the string "Warning: Failed to add ttynull console. No stdin, stdout, and stderr for the init process!" appearing on the console, which the rcutorture scripting interprets as a warning, which causes every rcutorture run to be flagged. However, the rcutorture init process never attempts to do any I/O, and thus does not care that it has no stdin, stdout, or stderr. This commit therefore causes the rcutorture scripting to ignore this message. Signed-off-by: Paul E. McKenney

tools/rcutorture: Fix BUG parsing of console.log

2020-11-07T01:13:58Z

For the rcutorture test summary log file console.log of virtual machines is parsed. When a console.log contains "DEBUG", BUG counter is incremented because regular expression does not handle to ignore DEBUG.

rcuperf: Change rcuperf to rcuscale

2020-08-25T01:39:24Z

This commit further avoids conflation of rcuperf with the kernel's perf feature by renaming kernel/rcu/rcuperf.c to kernel/rcu/rcuscale.c, and also by similarly renaming the functions and variables inside this file. This has the side effect of changing the names of the kernel boot parameters, so kernel-parameters.txt and ver_functions.sh are also updated. The rcutorture --torture type was also updated from rcuperf to rcuscale. [ paulmck: Fix bugs located by Stephen Rothwell. ] Reported-by: Ingo Molnar Signed-off-by: Paul E. McKenney

torture: Declare parse-console.sh independence from rcutorture

2020-08-25T01:38:31Z

Currently, parse-torture.sh looks at the fifth field of torture-test console output for the version number. This works fine for rcutorture, but not for scftorture, which lacks the pointer field. This commit therefore adjusts matching lines so that the parse-console.sh awk script always sees the version number as the first field in the lines passed to it. Signed-off-by: Paul E. McKenney
