2017-04-22igt: Import basic amdgpu tests from libdrmChris Wilson
Simple copy and replace of the CUnit tests inside libdrm to form a basis for further prime integration testing. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2017-03-23lib: system() is bad, use libkmod insteadChris Wilson
For an as of yet unknown reason, calling system("modprobe") from inside igt/gem_wait causes kasan to spend 1-5 minutes copying the process pagetables. This evaporates if we replace the fork-happy call to system with a call to load the module using libkmod. So be it. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2017-03-21Revert "lib: Open debugfs files for the given DRM device"Tomeu Vizoso
This reverts commit 301ad44cdf1b868b1ab89096721da91fa8541fdc. When a render-only device is opened and gem_quiescent_gpu is called, we need to use the debugfs dir for the master device instead. Signed-off-by: Tomeu Vizoso <tomeu.vizoso@collabora.com>
2017-03-21lib: Open debugfs files for the given DRM deviceTomeu Vizoso
When opening a DRM debugfs file, locate the right path based on the given DRM device FD. This is needed so, in setups with more than one DRM device, any operations on debugfs files affect the expected DRM device. v2: - rebased and fixed new API additions v3: - updated chamelium test, which was missed previously - use the minor of the device for the debugfs path, not the major - have a proper exit handler for calling igt_hpd_storm_reset with the right device fd.

2016-11-29lib: add igt_dummyloadAbdiel Janulgue
A lot of igt testcases need some GPU workload to make sure a race window is big enough. Unfortunately having a fixed amount of workload leads to spurious test failures or overly long runtimes on some fast/slow platforms. This library contains functionality to submit GPU workloads that should consume exactly a specific amount of time. Since v14: Since we are using multiple signals, walk list of batches to terminate a batch to avoid using a single global batch. Cycle signals between SIGRTMIN and SIGRTMAX properly.

2016-10-18drmtest: Install exithandler for i915, even in multidriver testsChris Wilson
If we opened the driver multiple times, we would not flush i915 if it was opened second. The persistence of one test state into a second can upset third parties, e.g. prime_vgem upsetting vgem_basic (due to references from i915.ko to vgem.ko preventing module unload).

2016-06-30lib: Start weaning off defunct intel_chipset.hChris Wilson
Several years ago we made the plan of only having one canonical source for i915_pciids.h, the kernel and everyone importing their definitions from that. For consistency, we style the intel_device_info after the kernel, most notably using a generation mask and a per-codename bitfield. This first step converts looking up the generation for a devid tree from a massive if(devid)-chain to a (cached) table lookup. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-06-28lib: Avoid running gem_quiescent_gpu() on non-Intel hardwareRobert Foss

2015-09-11lib: adding drm_open_driver() interfaceMicah Fedke
The drm_open_driver*() functions replace the drm_open_any*() functions and provide the same utility, but in a way that is platform agnostic, not intel-specific. This opens the path for adopting intel-gpu-tools to non-intel platforms. This commit renames the calls and adds the chipset parameter which can be used to restrict the opening to a specific hardware family. For example, drm_open_driver(DRIVER_INTEL) will only return a valid fd if an intel GPU is found on the system, along with performing intel-specific initialization stuff like gem_quiescent_gpu(), et al. If OPEN_ANY_GPU is specified, the first available drm device of any type will be opened. Other hardware type flags may be added in the future. The drm_open_any*() calls are retained as aliases of drm_open_driver*(OPEN_ANY_GPU) but will be removed in a subsequent patch.
