By -r I assume you mean --run-subtest? Running a test with -r <subtest> just prints the usage options at the moment. Allowing it to be added multiple times could be a way of building up a list of subtests to run, but a completely new command line option would need to then be added (--skip-subtest?) to allow building up a list of subtests to be skipped. With my change as is, it allows a string to be passed to the test which details which subtests should be run. If a new parameter such as --skip-subtest is added then it would require knowledge of whether the string contains subtests to run or not to run. That would complicate any scripts that use this to automate testing. Allowing --run-subtest (and --skip-subtest) to be specified multiple times will also complicate the code in igt_core.c. Currently there is a simple call to strdup(). If --run-subtest can be specified multiple times the code will have to deal with concatenating strings and any memory reallocation that needs. Also how to deal with the possibility of multiple wildcard expressions? I think that will just end up more complicated than the simple separated list solution this patch introduces. //Derek > >> >> Any subtest string not starting : or ^ is treated as a normal wildcard >> expression. >> >> This is required mainly on android to exclude subtests that test >> features that do not exist in the android driver while still being >> able to run other subtests in the binary when a wildcard expression is >> insufficient. >> >> Signed-off-by: Derek Morton <[email protected]> >> --- >> lib/igt_core.c | 42 ++++++++++++++++++++++++++++++++++++++++-- >> 1 file changed, 40 insertions(+), 2 deletions(-) >> >> diff --git a/lib/igt_core.c b/lib/igt_core.c index 6b69bb7..b9e7470 >> 100644 >> --- a/lib/igt_core.c >> +++ b/lib/igt_core.c >> @@ -207,7 +207,15 @@ >> * To do that obtain the lists of subtests with "--list-subtests", which >> can be >> * run as non-root and doesn't require the i915 driver to be loaded (or any >> * intel gpu to be present).
