2016-12-23stubs/intel_bufmgr: Suppress GCC compilation warningsChris Wilson
GCC likes to complain that every function here dies in an assert and doesn't return, which is very true but not one we wish to optimise for. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-12-22lib: Kick all fbconChris Wilson
i915 may not be the only, nor the first, vtcon framebuffer device - we need to check them all! Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-12-22lib/selftest: Query module parameter for error code.Chris Wilson
"Live" selftesting of i915.ko happens during device probing which eats the error code and does not propagate it back to module loading. Workaround this by writing the error code back to the module parameter and probing it after a "successful" install. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-12-19lib/debugfs: Check if debufs is already mounted before attempting to mount itVille Syrjälä
mount("/sys/kernel/debug") will return an error if something is already mounted there. So let's check for that before calling mount(). This allows many of the tools (eg. intel_reg) to work even when no drm drivers are loaded since the earlier "/sys/kernel/debug/dri" & co. path checks will fail in that case and we will fall back to attempting to mount debugfs ourselves.

2016-12-17lib/sw_sync: Use timeline/fence instead of generic fdChris Wilson
whilst we may be passing around file descriptions, using fence or timeline as appropriate is more descriptive. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-12-17lib/sw_sync: Rename sync_fence_create()Chris Wilson
It takes a sw_sync_timeline and returns a fence (it is a factory), so call it sw_sync_timeline_create_fence() for better self-documentation. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-12-17lib/sw_sync: Indicate that sync_merge() operates and create a sync_fenceChris Wilson
Improvements to self-documentating API that matches the rest of sw_sync. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-12-17lib/sw_sync: Bring sync_wait() API into lineChris Wilson
igt likes to return kernel-esque negative errno where we can, and indicate that we expect to operate on a sync_fence, otherwise it is merely a grandiose poll(). Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-12-17lib/sw_sync: Provide compatiblity stubs for old headersChris Wilson
Common practice for igt when providing tests for new features in unreleased kernels is to include a complete set of uABI stubs. Lack of such compatability breaks compilation on current distributions' kernel headers. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-12-17igt_kms: Use const parameters for igt_assert_crc_equalLyude
Since we're not modifying these anywhere, let's make them const so as to not break code doing comparisons against compile-time CRCs. Signed-off-by: Lyude <lyude@redhat.com> Tested-by: Robert Foss <robert.foss@collabora.com>
2016-12-17lib/igt_kmod: kmod already supplies a cooked error codeChris Wilson
kmod already does the err = -errno for us. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-12-16stubs/drm: Add drm_intel_gem_context_get_id stubRobert Bragg
The plan is to use this api in i915-perf tests so this adds the corresponding stub in case libdrm was built with libdrm_intel disabled. Signed-off-by: Robert Bragg <robert@sixbynine.org> Reviewed-by: Matthew Auld <matthew.auld@intel.com>
2016-12-14lib/debugfs: Support new generic ABI for CRC captureTomeu Vizoso
The kernel has now a new debugfs ABI that can also allow capturing frame CRCs for drivers other than i915. Add alternative codepaths so the new ABI is used if the kernel is recent enough, and fall back to the legacy ABI if not.

2016-12-13igt_kms: Dynamically allocate igt_display->pipesLyude
Many GPUs have more then 3 pipes available, so hard limiting this to I915_MAX_PIPES prevents us from using anything that relies on igt_display_init() on non-intel systems (since we end up writing out of bounds and seg faulting). Fix this by dynamically allocating igt_display->pipes using the number of pipes we've detected on the GPU.

2016-12-08igt_kms: Remove support for drivers with <1 drm_planeLyude
We've had support for universal planes since kernel version 3.15, so there's not really a good reason to try supporting drivers that lack plane support now. As well, the current has_universal_planes logic is broken anyway as it makes the assumption that having display planes always means we have both a primary plane and a cursor plane (this isn't true on radeon/amdgpu and nouveau). So, remove this, and just check for whether or not we have a cursor plane. Signed-off-by: Lyude <lyude@redhat.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>

This reverts commit 721866d83907c8ade5d20121418261d715b145ed. Still required for late tests as ->probe() is not allowed to return 1, but must return a negative error code.
2016-12-07lib/kselftests: Eliminate ENOTTY hackChris Wilson
Returning a positive value from module loading does not get interpretted as an error, so we can forgo passing a proxy value of -ENOTTY. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

Due to the unconditional call to intel_get_drm_devid() in kmstest_force_connector(), trying to use this function on anything that isn't intel hardware results in the current fixture being skipped.

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.
