2023-03-24tools/memory-model: Add "--" to parseargs.sh for additional argumentsPaul E. McKenney
Currently, parseargs.sh expects to consume all the command-line arguments, which prevents the calling script from having any of its own arguments. This commit therefore causes parseargs.sh to stop consuming arguments when it encounters a "--" argument, leaving any remaining arguments for the calling script. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
2023-03-24tools/memory-model: Fix scripting --jobs argumentPaul E. McKenney
The parseargs.sh regular expression for the --jobs argument incorrectly requires that the number of jobs be at least 10, that is, have at least two digits. This commit therefore adjusts this regular expression to allow single-digit numbers of jobs to be specified. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
2023-03-24tools/memory-model: Update parseargs.sh for hardware verificationPaul E. McKenney
This commit adds a --hw argument to parseargs.sh to specify the CPU family for a hardware verification. For example, "--hw AArch64" will specify that a C-language litmus test is to be translated to ARMv8 and the result verified. This will set the LKMM_HW_MAP_FILE environment variable accordingly. If there is no --hw argument, this environment variable will be set to the empty string. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>

2019-01-21tools/memory-model: Make scripts take "-j" abbreviation for "--jobs"Paul E. McKenney
The "--jobs" argument to the litmus-test scripts is similar to the "-jN" argument to "make", so this commit allows the "-jN" form as well. While in the area, it also prohibits the various forms of "-j0". Suggested-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Paul E.

2019-01-21tools/memory-model: Add scripts to check github litmus testsPaul E. McKenney
The https://github.com/paulmckrcu/litmus repository contains a large number of C-language litmus tests that include "Result:" comments predicting the verification result. This commit adds a number of scripts that run tests on these litmus tests: checkghlitmus.sh: Runs all litmus tests in the https://github.com/paulmckrcu/litmus archive that are C-language and that have "Result:" comment lines documenting expected results, comparing the actual results to those expected. Clones the repository if it has not already been cloned into the "tools/memory-model/litmus" directory. initlitmushist.sh Run all litmus tests having no more than the specified number of processes given a specified timeout, recording the results in .litmus.out files. Clones the repository if it has not already been cloned into the "tools/memory-model/litmus" directory. newlitmushist.sh For all new or updated litmus tests having no more than the specified number of processes given a specified timeout, run and record the results in .litmus.out files. checklitmushist.sh Run all litmus tests having .litmus.out files from previous initlitmushist.sh or newlitmushist.sh runs, comparing the herd output to that of the original runs. The above scripts will run litmus tests concurrently, by default with one job per available CPU. Giving any of these scripts the --help argument will cause them to print usage information. This commit also adds a number of helper scripts that are not intended to be invoked from the command line: cmplitmushist.sh: Compare the output of two different runs of the same litmus test. judgelitmus.sh: Compare the output of a litmus test to its "Result:" comment line. parseargs.sh: Parse command-line arguments. runlitmushist.sh: Run the litmus tests whose pathnames are provided one per line on standard input. While in the area, this commit also makes the existing checklitmus.sh and checkalllitmus.sh scripts use parseargs.sh in order to provide a bit of uniformity. In addition, per-litmus-test status output is directed to stdout, while end-of-test summary information is directed to stderr. Finally, the error flag standardizes on "!!!" to assist those familiar with rcutorture output. The defaults for the parseargs.sh arguments may be overridden by using environment variables: LKMM_DESTDIR for --destdir, LKMM_HERD_OPTIONS for --herdoptions, LKMM_JOBS for --jobs, LKMM_PROCS for --procs, and LKMM_TIMEOUT for --timeout.
