John Harrison 79bbcc299f drm/i915: Reserve space improvements ... An earlier patch was added to reserve space in the ring buffer for the commands issued during 'add_request()'. The initial version was pessimistic in the way it handled buffer wrapping and would cause premature wraps and thus waste ring space. This patch updates the code to better handle the wrap case. It no longer enforces that the space being asked for and the reserved space are a single contiguous block. Instead, it allows the reserve to be on the far end of a wrap operation. It still guarantees that the space is available so when the wrap occurs, no wait will happen. Thus the wrap cannot fail which is the whole point of the exercise. Also fixed a merge failure with some comments from the original patch. v2: Incorporated suggestion by David Gordon to move the wrap code inside the prepare function and thus allow a single combined wait_for_space() call rather than doing one before the wrap and another after. This also makes the prepare code much simpler and easier to follow. v3: Fix for 'effective_size' vs 'size' during ring buffer remainder calculations (spotted by Tomas Elf).
