patches 1-6 are various fixes and cleanups in our existing wait_request handling code. The purpose here is to consolidate as much code as possible into core waiting functions, and to prepare those core functions for atomic access. patches 7-8 are the patches we actually care about - timeout parameters within the core functions patch 9 is the ioctl interface to wait on a given buffer for some amount of time patch 10 is just something which annoys me The libdrm and i-g-t patches I am testing with are here: http://cgit.freedesktop.org/~bwidawsk/drm/commit/?h=wait_render&id=719212fbdbcf478ebf2931040c6b415d2765383e http://cgit.freedesktop.org/~bwidawsk/intel-gpu-tools/commit/?h=wait_render&id=31dcb8379d3b263a91a85db911559317321c6b7c 100ms seems to be sufficient to complete the test on my SNB. Note to anyone who dare review this: I cannot explain why, but my i-g-t test when set with a value to actually complete (100ms), always returns a multiple of a 1000000 nanoseconds. This probably means a bug lurks somewhere, but I haven't been able to find it. It is likely something very stupid. Also, I cannot figure out a good i-g-t test to upstream since the amount of time to timeout can vary quite a bit. However the test above is good for basic functionality.
