From 16d42f2f3dcc8bec8d75b53d1e9e9cf5af6e528c Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Sun, 20 Nov 2016 00:04:42 -0500 Subject: [PATCH] swr: call swr_update_derived unconditionally when drawing/clearing Currently a sequence like draw/map/draw/map will cause the second map to not wait for the second draw. This is because the first map will clear the resource business bit, and the second draw won't reset it since no state has changed. swr_update_derived does a tiny bit of extra work, including updating the SWR_BACKEND_STATE as well as waiting for prending fences. If that's a problem, we could call swr_update_resource_status directly from draw/clear handlers. Fixes clearbuffer-stencil, clearbuffer-depth, clearbuffer-depth-stencil, and clearbuffer-display-lists.
