2016-05-12lib/igt_aux: Polish docs for igt_timeoutDaniel Vetter
Add docs, rename parameter and rename the macro to igt_do_timeout to make it clear it works like a loop. v2: Rename instead to igt_until_timeout (Chris). Acked-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
2016-05-12lib/igt_aux: Polish docs for igt_interruptibleDaniel Vetter
- Give __ prefix to internal funcstion and structs, only igt_interruptible is used by tests. - Move docs to igt_interruptible and adjust. - Explain more clearly how the timeout is getting doubled each iteration until no more interruptions happen. Also rename the argument to give it a more meaningful name in the docs. - Link from other functions to this one for cross-referencing. - Rename to igt_do_interruptible to make it clearer it's a loop, inspired by do {} while () loops. v2: Rename instead to igt_while_interruptible and fix typos (Chris). And add gtk-doc for igt_ioctl, too. Acked-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
2016-05-11benchmarks/, overlay/, demos/, tools/, tests/: Add optional Werror.marius vlad
v2: Initially added Werror by default. Make it optional so it doesn't break android build and (potential) distros maintaing the package (Hinted by Damien Lespiau). --enable-werror will enable -Werror compiler flag.

2016-05-09prime_mmap_kms: show case dma-buf new API and processes restrictionsTiago Vignatti
dma-buf new API consists of: - mmap(dma_buf_fd, ...): the ability to map a dma-buf file-descriptor of a graphics buffer to the userspace, and more importantly, to actually write on the mapped pointer (which was not possible before). It’s worth noting that the Direct Rendering Manager (DRM) and the hardware driver implementation are fundamentally important to safely export the graphics handle to be mapped. - ioctl(dma_buf_fd, DMA_BUF_IOCTL_SYNC, &args): cache coherency management in cases where the CPU and GPU devices are being accessed through dma-buf at the same time. Coherency markers, which forward directly to existing dma-buf device drivers vfunc hooks, are exposed to the userspace through the DMA_BUF_IOCTL_SYNC ioctl and have to be used before and after the mapped area is accessed. This is fundamentally important in hardware architectures where the graphics engine and the CPU cores don't share caches but also important in other type of hardware where the memory hierarchy is (most of the time) coherent. More details can be found in this patch set: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c11e391da2a8fe973c3c2398452000bed505851e v2: use uint32_t for color type, increment the variable and add --interactive-debug=paint v3: use igt_display_commit() to mode set the crtc so the rectangle is shown painted; also added Testcase description on the beginning of the file. v4: remove crtc actually which seems superfluous; add a igt_skip_on in case support for dma-buf mmap is nonexistent.

2016-05-06igt/gem_exec_flush: Restrict BAT batch testingChris Wilson
Only do one mode of batch writing for BAT, and hope that is sufficient to route out all the coherency problems when doing the cmdparser and when not. We still have the full set for non-BAT, just less of a smokescreen. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-05-04igt/gem_exec_flush: Halve the number of BAT tests, but double their runtimeChris Wilson
