From 08c71740ad609b26477b4062bb1794bb322e8b43 Mon Sep 17 00:00:00 2001 From: Nicolai Hähnle Date: Sun, 10 Jan 2016 19:54:44 -0500 Subject: gallium/radeon: reset valid_buffer_range on PIPE_TRANSFER_DISCARD_WHOLE_RESOURCE MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This accomodates a streaming pattern where the discard flag is set when the application wraps back to the beginning of the buffer.
