From 8c43b79b21929e9e54e13e892f7787e222e73f39 Mon Sep 17 00:00:00 2001 From: Pauli Nieminen Date: Tue, 18 Aug 2009 18:51:38 +0300 Subject: libdrm_radeon: Optimize copy of table to cs buffer with specialized call. Using this call in OUT_BATCH_TABLE reduces radeonEmitState cpu usage from 9% to 5% and emit_vpu goes from 7% to 1.5%. I did use calgrind to profile gears for cpu hotspots with r500 card.
