From 06c53e9ae44f1759740738d5ea8029594da31e56 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Mon, 22 Jan 2018 13:49:22 +0100 Subject: lib/intel_batchbuffer: Add delta argument to igt_blitter_fast_copy__raw, v2. Adding a delta offset will allow us to copy planar framebuffers with this function. Changes since v1: - Set src and destination addresses to the delta, in case BO is mapped at offset 0.
