From 5375d009be1811e22f654ea82a04164a5752022c Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Tue, 2 Jul 2019 14:26:02 +0200 Subject: panfrost: Pass referenced BOs to the SUBMIT ioctls Instead of manually adding the BOs from the various SLAB pools plus the one backing the color FB, we insert them in the BO set attached to the job and let panfrost_drm_submit_job() pass all BOs from this set to the SUBMIT ioctl. This means we are now passing all referenced BOs and let the scheduler wait on referenced BO fences if needed.
