From 7055068eeae7f64166cca513282829d5a3e9b9d3 Mon Sep 17 00:00:00 2001 From: Jerome Glisse Date: Wed, 8 Dec 2010 13:41:25 -0500 Subject: r600g: specialized upload manager Allow important performance increase by doing hw specific implementation of the upload manager helper. Drop the range flushing that is not hit with this code (and wasn't with previous neither). Performance improvement are mostly visible on slow CPU.
