2015-02-18lib: Cache DRM device id to reduce number of ioctlsChris Wilson
The DRM device id for the igfx is fixed, since there can only be one in the system. So once we query it for the first time we can safely report that value on every subsequent request, cutting out a lot of noisy ioctls from inside tests. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-02-13lib/igt_gt: Document and consolidateDaniel Vetter
Also move forcewake and stop_rings code from igt_debugfs to igt_gt since it fits better. And move the hang injection fork helpers from igt_aux to igt_gt, too. Also push the intel_gen call into igt_hang_ring while at it. Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
2015-01-19igt/drv_module_reload: Check more carefully for a live driverChris Wilson
As drm_open_any() now quietly fails if there is no driver, this nullifies the effectiviness of using gem_exec_nop as the test for a good reload. Combine with gem_alive (and guarantee that gem_alive can detect a dead driver, putting lie to commit 032f30cb38bb03562ee7fde19cd278b1d8ac31a9 Author: Thomas Wood <thomas.wood@intel.com> Date: Tue Jan 13 13:33:57 2015 +0000 lib: remove unnecessary checks on the drm_open_any return value ) first.

2014-03-26lib/igt_kms/bf: doc skeletonDaniel Vetter
igt_kms docs are just skeleton and also added igt_fb to make sure the linking works correctly. Next up: Actually documenting igt_fb. Also fix that depency spelling fumble I've copied around to a few too many places. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2014-03-23lib/drmtest: api documentationDaniel Vetter
Also rename the arguments of do_ioctl a bit for better clarity. I haven't figured out a way to reference other section headers, hence the links to igt_core and intel_batchbuffer are a bit fragile unfortunately. It gets the job done though. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2014-03-23lib: extract igt_aux.[hc]Daniel Vetter
And shovel all the various helpers in there. Also move igt_set_vt_graphics_mode to igt_kms.h since the function is implemented in igt_kms.c. And it fits better. I kinda missed this in the prep work. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2014-03-22lib: s/drmtest_dumb_aub/igt_aub_dump_enabled/Daniel Vetter
This is prep work to extract a new igt aux library with all kinds of random stuff. Also give it a bit a more suitable name to indicate that this is just a flag and doesn't do the aub dumping itself. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2014-03-22lib: rename intel_gpu_tools.h to intel_io.hDaniel Vetter
With the header cleanup we can now give this header a suitable name, since it now really only contains register access and other I/O functions and assorted definitions. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2014-03-22lib: remove uncessary #includes from headersDaniel Vetter
Only include what the header itself needs. The big fish here is intel-gpu-tools.h. More will follow. One ugly thing removed here is the duplicated GEN6_TD_CTL #define, one of which was broken. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2014-03-22tests|lib: remove assert.h includesDaniel Vetter
Only the igt core and non-test tools should have asserts to catch internal errors, tests and helper libraries should all user igt_asert instead. Fix things up where assert instead of igt_assert was used. One tiny step towards header sanity. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2014-03-12lib: extract igt_core.cDaniel Vetter
Same game as with ioctl_wrappers.c. To split was rather clean except for the static function oom_adjust_for_doom. But that was a bug, the calls to it in the various open helpers should simply be done at init and fork time. Which was already the case, except for simple testcase. So fix it up. While at it also start with a small section header for the documentation. v2: Don't forget to update the xml template ... Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2014-03-12lib/ioctl_wrappers: api docDaniel Vetter
Also some tiny polish to function interface: - @caching in gem_set_tiling should be uint32_t to match the ioctl struct. - s/size/length/ for gem_write/read. - move gem_get_num_rings to the other ring feature helpers. v2: Also demote gem_require_ring from static inline and move it, too. v3: Also move gem_handle_to_libdrm_bo.

2014-03-11lib: extract ioctl_wrappers.cDaniel Vetter
I want to group the ioctl wrappers and related functions into their own documentation section. Apparently gtkdoc refuses to obey this wish without a corespdonding header. So appease it. Also gtkdoc seems to struggle with rebuilding a bit ... Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2014-02-13lib: (somewhat) structured logging supportDaniel Vetter
Apparently there's a bit a need for more verbose output in testcases, mostly for debugging purposes. At least gem_reset_stats and pm_rps have a verbose mode. On top of that we're currently not taking advantage of piglit's "warn" state all that much. But I think it might be useful for testcases which are notorious for some kinds of spurious failures, like e.g. the really nasty timing checks in kms_flip. If we demote some of them to just warnings we could run the overall tests more often. Hence this patchs adds a new igt_log function with the three levels DEBUG, INFO and WARN. Plus a bunch of convenience helpers to keep the test code tidy. The level can be set through an enviroment vairable IGT_LOG_LEVEL with info being the default. Also tests can look at the selected log level in case they want to run costly debug functions only when needed. Comments highly welcome, I plan to roll this out over tests which can use it (not all, imo that's too much churn) once we've settled on the interfaces/semantics. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2014-02-12lib: Make igt_skip noreturnDaniel Vetter
This is a remnant from the subtest code before we had proper fixture blocks. With those there's no no reason to have igt_skip calls outside of fixtures or subtests, so we can assert this and hence always jump out. Suggested by Thomas Wood since static analyzers got confused about this. To check for fallout I've run all tests as non-root so that they'll all skip. Only very little fallout resulted.

2014-02-12lib: install exit handler only on success for prefault controlDaniel Vetter

2014-02-11lib/drmtest: Fix up skip_henceforth checksDaniel Vetter
We need to first check whether we'll even run the testcase before deciding to print a premature SKIP/FAIL. Without this and global skipped resulted in superflous output when running only one testcase.

Provide two arguments version, and verbose, which allow printing from an arbitrary igt test. It will show system information (from build time, not runtime), as well as the git SHA being used.

2013-12-03drmtest: Avoid wrong PID/TID after clone racesTvrtko Ursulin
Various C library implementations have various races with regards to caching getpid() or TID inside pthread_kill() implementations. For example see clone(2) glibc man page and pthread_kill Bionic C library source. Work around that by making sure correct PID/TGID and TID values are retrieved from the kernel when re-raising the signal. It can be delivered immediately after the clone system call while C library cached copies have not yet been updated.
