From d38ec24f531fac0b53c406a09d17427309a3ffca Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Mon, 22 Jan 2018 23:40:48 -0800 Subject: i965/miptree: Add an aux_disabled parameter to render_aux_usage Only one of the callers of intel_miptree_render_aux_usage actually took brw->draw_aux_buffer_disabled into account. This was causing us to ignore draw_aux_buffer_disabled for the intel_miptree_prepare_render. This isn't a problem because the draw_aux_buffer_disabled entry was set during texture preparation and we already did the resolve at that time. However, this also meant that the aux_usage we were passing to brw_cache_flush_for_render and brw_render_cache_add_bo was wrong so our automatic cache flushing around aux_usage changes wasn't happening. This was causing GPU hangs in Oxenfree.
