2015-01-20kms_plane: Add test that suspends/resumes before getting crcAnder Conselvan de Oliveira
This adds a test that does a suspend/resume cycle between configuring a plane and getting the crc value for the pipe. The intention is to test if the user requested stated is restored properly, instead of being clobbered by the state read out from the hardware.

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.

2015-01-13igt/gem_mmap_wc: Reorder gem_close()Chris Wilson
Unlike a GTT mmap, a WC mmap does not have a direct reference to the object, only to the backing storage. If we want to control the domain correctly for mmap(wc), we have to keep the bo reference around.

2015-01-07igt/gem_concurrent_blit: Inject hangs before verifying contentsChris Wilson
After setting up the copy operations, add a hanging batch. This should mean that we complete the copy and the compare then races against the GEM reset. Hopefully, this will catch driver bugs where the target object is no longer accessible after the hang. Note: hang injection is disabled until the required kernel interface is completed. But there are useful additional tests here... Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2015-01-06igt/gem_tiled_wc: Exercise wc mmaps with swizzlingChris Wilson
This exercises both the wc mmappings and the extended get_tiling ioctl. Userspace cannot handle bit17 swizzling through wc mmaps (because bit17 requires swizzling based on the actual physical address of the page - which is unknown to userspace) and so we need an extended get_tiling ioctl to report the actual as well as the logical swizzling on an object. We then check that the contents of the object are tiled and swizzled correctly when viewed through a wc mmap.

2014-12-11lib: add a function to lock memory into RAMThomas Wood
Add a function to lock memory into RAM and use it in the gem_tiled_swapping test to reduce the amount of allocated memory required to force swapping. This also reduces the amount of time required for the test to complete, since the data set is smaller. The following durations were recorded with gem_tiled_swapping on a haswell system before the change: Subtest non-threaded: SUCCESS (55.889s) Subtest threaded: SUCCESS (810.532s) and after: Subtest non-threaded: SUCCESS (11.804s) Subtest threaded: SUCCESS (268.336s) v2: add various assertions and requirements and make sure gem_tiled_swapping works on systems with less RAM (Daniel Vetter) v3: fix allocation size calculation Signed-off-by: Thomas Wood <thomas.wood@intel.com>

2014-12-08tests/pm_rps: vlv: round middle point to freq supported by HWImre Deak
When setting the calculated middle frequency value the test assumes that the HW/kernel rounds this value according to a 50MHz step value. This is not so at least on VLV/CHV, on my B0 BYT-M for example this step value is 22MHz, so there the test will fail. To fix this get the nearest supported value by setting the target frequency as a min or max frequency and read it back. The kernel will round the returned value to the nearest supported. v2: - remove the 50MHz rounding that was done for non-VLV platforms, the new way of rounding should provide the correct value for all platforms (Ville) Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Imre Deak <imre.deak@intel.com>
2014-12-08tests/pm_rps: vlv: load gpu for idle min/max testsImre Deak
When changing the sysfs GT min/max frequencies, the kernel won't explicitly change the current frequency, unless it becomes out of bound based on the new min/max values. The test happens to work on non-VLV platforms because on those the kernel resets the current frequency unconditionally (to adjust the RPS interrupt mask as a side-effect) and that will lead to an RPS interrupt setting the minimum frequency. To fix this load the GPU after decreasing the min frequency and before checking the current frequency. This should set the current frequency to the minimum.

2014-12-08tests/pm_rps: vlv: wait for freq to settleImre Deak
At least on VLV when forcing a new GT frequency by writing to the min/max freq sysfs entries the kernel doesn't wait until the new frequency settles, so the subsequent readback check might fail. To fix this wait until the current frequency is between the min/max values using a 10ms timeout. Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Imre Deak <imre.deak@intel.com>
