X-Git-Tag: upstream/23.3.3~10158 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=958ea2ec2a328e5797eed9898995a04dd82e5f0e;p=platform%2Fupstream%2Fmesa.git radv: Split submission in winsys instead of radv_queue. This will still make it so that RADV_DEBUG=hang will only submit one command buffer at a time, but otherwise let's pass all CS objects into one submission and let the winsys split them if necessary. The winsys can do a better job at splitting them because radv_queue has no knowledge of IBs and ignores chaining in the splitting logic.
