Case in point: virtio-gpu.ko is "virtio_gpu". I would suggest leaving the kernel module loading plans later for now and get the DRIVER_ANY match forcing in place. Or even forget kernel module loading entirely. If the user is able to set a parameter to a module name, the user can load the module themselves before running tests. It won't get unloaded if IGT doesn't have a test that does it, and it won't have such a test unless it knows about the driver/module. And at that point, IGT will know how to load that module. > + for (const struct module *m = modules; m->module; m++) { > + if (chipset & m->bit) { > + if (m->modprobe) > + m->modprobe(m->module); > + else > + modprobe(m->module); > + } > } > } > pthread_mutex_unlock(&mutex); > diff --git a/lib/igt_core.c b/lib/igt_core.c > index 5092a3f0..ee085e2a 100644 > --- a/lib/igt_core.c > +++ b/lib/igt_core.c > @@ -286,6 +286,7 @@ enum { > OPT_DESCRIPTION, > OPT_DEBUG, > OPT_INTERACTIVE_DEBUG, > + OPT_FORCE_MODULE, > OPT_HELP = 'h' > }; > > @@ -303,6 +304,23 @@ static pthread_mutex_t log_buffer_mutex = PTHREAD_MUTEX_INITIALIZER; > GKeyFile *igt_key_file; > #endif > > +char *target_module = NULL; > + > +void set_target_module(char *target) > +{ > + if (!target) > + igt_warn("No module specified, keep default behaviour"); > + > + target_module = target; > +} > + > +const char *get_target_module(void) > +{ > + if (target_module) > + return target_module; > + return NULL; > +} > + > char *igt_frame_dump_path; > > const char *igt_test_name(void) > @@ -555,6 +573,7 @@ static void print_usage(const char *help_str, bool output_on_stderr) > " --debug[=log-domain]\n" > " --interactive-debug[=domain]\n" > " --help-description\n" > + " --force-module <module>\n" > " --help\n"); > if (help_str) > fprintf(f, "%s\n", help_str); > @@ -666,6 +685,7 @@ static int common_init(int *argc, char **argv, > {"debug", optional_argument, 0, OPT_DEBUG}, > {"interactive-debug", optional_argument, 0, OPT_INTERACTIVE_DEBUG}, > {"help", 0, 0, OPT_HELP}, > + {"force-module", required_argument, 0, OPT_FORCE_MODULE}, > {0, 0, 0, 0} > }; > char *short_opts; > @@ -763,6 +783,9 @@ static int common_init(int *argc, char **argv, > print_test_description(); > ret = -1; > goto out; > + case OPT_FORCE_MODULE: > + set_target_module(strdup(optarg)); > + break; > case OPT_HELP: > print_usage(help_str, false); > ret = -1; > diff --git a/lib/igt_core.h b/lib/igt_core.h > index bf8cd66c..6d635ebd 100644 > --- a/lib/igt_core.h > +++ b/lib/igt_core.h > @@ -50,6 +50,10 @@ extern const char* __igt_test_description __attribute__((weak)); > extern bool __igt_plain_output; > extern char *igt_frame_dump_path; > > +extern char *target_module; > +void set_target_module(char *target); > +const char *get_target_module(void); > + > /** > * IGT_TEST_DESCRIPTION: > * @str: description string > diff --git a/scripts/run-tests.sh b/scripts/run-tests.sh > index 4209dd8c..29aa50a8 100755 > --- a/scripts/run-tests.sh > +++ b/scripts/run-tests.sh > @@ -80,6 +80,7 @@ function print_help { > echo " (can be used more than once)" > echo " -T <filename> run tests listed in testlist" > echo " (overrides -t and -x)" > + echo " -f <module> force specific module load" > echo " -v enable verbose mode" > echo " -x <regex> exclude tests that match the regular expression" > echo " (can be used more than once)" > @@ -91,7 +92,7 @@ function print_help { > echo "Useful patterns for test filtering are described in the API documentation." > } > > -while getopts ":dhlr:st:T:vx:Rn" opt; do > +while getopts ":dhlr:st:T:m:vx:Rn" opt; do > case $opt in > d) download_piglit; exit ;; > h) print_help; exit ;; > @@ -100,6 +101,7 @@ while getopts ":dhlr:st:T:vx:Rn" opt; do > s) SUMMARY="html" ;; > t) FILTER="$FILTER -t $OPTARG" ;; > T) FILTER="$FILTER --test-list $OPTARG" ;; > + f) FILTER="$FILTER --force-module $OPTARG" ;; This command line is given to piglit, not the IGT tests. Furthermore, run-tests.sh is not required to run tests. One can execute piglit or igt_runner directly. Rather, consider having the force driver name passed via environment variables.

I mean that when a test calls drm_open_driver(DRIVER_ANY), it will happily open /dev/dri/card0 and use that if it's, say, an i915 device.
