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

torture: Abstract out console-log error detection

2020-06-29T19:01:44Z

This commit pulls the simple pattern-based error detection from the console log into a new console-badness.sh file. This will enable future commits to end a run on the first error. Signed-off-by: Paul E. McKenney

rcutorture: Handle non-statistic bang-string error messages

2020-06-29T19:01:44Z

The current console parsing assumes that console lines containing "!!!" are statistics lines from which it can parse the number of rcutorture too-short grace-period failures. This prints confusing output for other problems, including memory exhaustion. This commit therefore differentiates between these cases and prints an appropriate error string. Signed-off-by: Paul E. McKenney

refscale: Change --torture type from refperf to refscale
