From ed53e61bec9e926b60ede093d4dd2bac56a4c605 Mon Sep 17 00:00:00 2001 From: Erik Faye-Lund Date: Mon, 6 May 2019 15:35:04 +0200 Subject: llvmpipe: pass stream-out targets to draw-module early We currently set this state in the draw-module twice on each draw, but which trashes this state. So far that's not a problem, because we don't really do much from that function. But it turns out, we're going to have to do more; namely flush when the state changes. This will incur a large performance penalty due to the excessive setting. Instead, let's rely on the CSO caching making sure that llvmpipe_set_so_targets doesn't get called needlessly, and setup the state directly there instead.
