2017-07-17lib: Add reset-type helper in ioctl_wrappersMichel Thierry
Soon we will have tests that are only for platforms with reset-engine (GEN8+), so add a helper to query the has_gpu_reset via the getparam ioctl. v2: Add more helper functions to avoid using magic numbers in tests (Arek).

When the memory backing the userptr object is released by the user, but the BO itself is not closed, it's possible to trigger recursive deadlock caused by operations done on different BO mapped in that region.

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.

2016-03-19lib: 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.

2016-02-11prime_mmap: Add basic tests to write in a bo using CPUTiago Vignatti
This patch adds test_correct_cpu_write, which maps the texture buffer through a prime fd and then writes directly to it using the CPU. It stresses the driver to guarantee cache synchronization among the different domains. This test also adds test_forked_cpu_write, which creates the GEM bo in one process and pass the prime handle of the it to another process, which in turn uses the handle only to map and write. Roughly speaking this test simulates Chrome OS architecture, where the Web content ("unpriviledged process") maps and CPU-draws a buffer, which was previously allocated in the GPU process ("priviledged process"). This requires kernel modifications (Daniel Thompson's "drm: prime: Honour O_RDWR during prime-handle-to-fd") and therefore prime_handle_to_fd_for_mmap is added to fail in case these lack. Also, upcoming tests (e.g. next patch) are going to use it as well, so make it public and available in the lib. v2: adds prime_handle_to_fd_with_mmap for skipping test in older kernels and test for invalid flags.
