From 7ef722861b691ce99be3827ed05f8c0ddf2cd66e Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Wed, 28 Nov 2018 08:50:19 -0500 Subject: [PATCH] freedreno/drm: sync uapi and enable softpin Pull in updated UAPI and use kernel API version to enable softpin. Since MSM_SUBMIT_BO_DUMP flag was added at same time, use that to signal to kernel that cmdstream buffers are useful to dump for debugging/cmdstream-traces.
