Daniel Vetter e62b59e413 drm/i915: Simplify flush_cpu_write_domain ... We can push down the decision whether to force flushing into the implementation since in all places that matter obj->pin_display is accurate already. The only place where the optimization really matters is the sw_finish_ioctl, and that already checks for obj->pin_display on its own. I suspect that this was simply an artifact of how commit 2c22569bba Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Aug 9 12:26:45 2013 +0100 drm/i915: Update rules for writing through the LLC with the cpu evolved - only v2 added the pin_display tracking. Note that we still retain the gist of this logic from the above commit with the explicit force argument for the low-level clflush function. Ville noted in his review that there's a slight behavioural change in the set_to_gtt_domain function, which now also will flush display plane data. This opens-open the potential for userspace to start doing buggy things by omitting the sw_finish_ioctl, which is why I've rejected a functional equivalent patch from Ville a while ago: http://lists.freedesktop.org/archives/intel-gfx/2013-November/036421.html But on second consideration it's not that evil, and in any case the justification here is more clarity, not allowing crazy userspace.
