2016-04-14lib: Expose is_i915_deviceTomeu Vizoso
Lib and test code can use this function to avoid i915-specific behavior when running on other drivers. Signed-off-by: Tomeu Vizoso <tomeu.vizoso@collabora.com> Reviewed-by: Daniel Stone <daniels@collabora.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2016-04-14lib: Have gem_set_tiling require intelTomeu Vizoso
Before calling a i915-specific IOCTL, require i915. This allows us to skip subtests that are specific to that driver, though what should eventually happen is that tests don't generally call gem_set_tiling directly but go through an abstraction layer that constructs the buffer object in a driver-specific way.

2016-04-12test/gem_mocs_settings: Testing MOCS register settingsPeter Antoine
The MOCS registers were added in Gen9 and define the caching policy. The registers are split into two sets. The first set controls the EDRAM policy and have a set for each engine, the second set controls the L3 policy. The two sets use the same index. The RCS registers and the L3CC registers are stored in the RCS context. The test checks that the registers are correct by checking the values by directly reading them via MMIO, then again it tests them by reading them from within a batch buffer. RCS engine is tested last as it programs the registers via a batch buffer and this will invalidate the test for workloads that don't use the render ring or don't run a render batch first. v2: Reorganised the structure. Added more tests. (Chris Wilson) v3: Fixed a few bugs. (Chris Wilson) v4: More Tidy-ups. (Chris Wilson) SKL does does not have a snoop bit.

2016-04-03lib: Avoid assertion if sig_ioctl is unsed from a child accidentallyChris Wilson
The timer is tied to the creator thread, i.e. it is not inheritable across fork() or clone()/pthread_create(). Using it thus causes an assertion failure in the test after the one that aborts (and so on until we perform an interruptible test correctly) - one mistake snowballs. We can stop the snowball by doing an initial check and diverting back to drmIoctl(). Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2016-03-21lib: Measure the cost of calling timer_settimer() for sigiterChris Wilson
We wish to delay the first signal from the igt_sigiter_ioctl sufficiently to skip over the timer_settime() and into the drmIoctl kernel context before firing. If we fire too early, we will think that the ioctl doesn't respond to signals and ignore it in future. If we fire too late, we won't probe the ioctl for signal handling at all. Let's try measuring the timer_settime() call time as a first approximation. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-03-19lib/igt_aux: Refine decision to stop signal injectionChris Wilson
The goal of injecting signals into the ioctl() is to trigger an EINTR. If we did not succeed on the last pass, we are not going to on the next or subsequent passes either. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-03-19igt/gem_concurrent_blit: dmabuf requires twice the number of filesChris Wilson
In order to keep the dmabuf mmap around whilst we keep the object alive, we need a file descriptor for each. Check that the VFS supports that many fd. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-03-19lib/igt_aux: Divert ioctls for signal injectionChris Wilson
To simplify and speed up running interruptible tests, use a custom ioctl() function that control the signaling and detect when we need no more iterations to trigger an interruption. We use a realtime timer to inject the signal after a certain delay, increasing the delay on every loop to try and exercise different code paths within the function. The first delay is very short such that we hopefully enter the kernel with a pending signal. Clients should use struct igt_sigiter iter = {}; while (igt_sigiter_repeat(&iter, enable_interrupts=true)) do_test() to automatically repeat the test until we can inject no more signals into the ioctls. This is condensed into a macro igt_interruptible(enable_interrupts=true) do_test(); for convenience. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-03-19lib: Replace drmIoctl() with a layer of indirectionChris Wilson
Insted of calling drmIoctl() directly, call igt_ioctl() instead. In the normal scenario this is function pointer that calls drmIoctl() (so no penalty), but allows us to divert ioctls into our own routines for nefarious purposes. One such purpose will be to control interrupt generation into the ioctl, to be able to detect when we successfully interrupt the ioctl and when we no longer need more interrupts.
