From: Alex Deucher Date: Wed, 22 Jun 2016 20:49:22 +0000 (-0400) Subject: drm/amdgpu/dce11: update async flip update time X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7359ee637d98cbd66b8d36341cfe03a9875b3897;p=linux-beck.git drm/amdgpu/dce11: update async flip update time Use UPDATE_IMMEDIATE (update on next data request boundary) rather than UPDATE_H_RETRACE (update on next line boundary). The data request boundary is less than a scanline, so it update will happen sooner.
