lifted from Daniel: pread/pwrite isn't about the object's domain at all, but purely about synchronizing for outstanding rendering. Replacing the call to set_to_gtt_domain with a wait_rendering would imo improve code readability. Furthermore we could pimp pread to only block for outstanding writes and not for reads. Since you're not the first one to trip over this: Can I volunteer you for a follow-up patch to fix this? v2: Switch the pwrite patch to use \!read_only. This was a typo in the original code. (Chris, Daniel) Recommended-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Ben Widawsky <ben@bwidawsk.net> [danvet: Fix up the logic fumble - wait_rendering has a bool readonly paramater, set_to_gtt_domain otoh has bool write. Breakage reported by Jani Nikula, I've double-checked that igt/gem_concurrent_blt/prw-* would have caught this.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> |
