A 13 Line Patch That Boosts Intel Sandy Bridge Performance in Linux

Posted on Friday, March 04 2011 @ 14:37:57 CET by

Phoronix reports about a 13-line patch that improves Linux performance on the Intel Sandy Bridge platform:
"After some initial Linux troubles, last month we finally got Intel Sandy Bridge graphics working under Linux. The latest Intel CPUs (such as the Core i5 2500K) with integrated graphics are blazingly fast, and the classic Intel Mesa driver was fast compared to other open-source Mesa / Gallium3D drivers, but it still was a ways behind the low-end discrete graphics cards with the proprietary AMD / NVIDIA drivers for Linux. It was also shown that the Intel Linux Mesa driver is much slower than the Intel Windows driver for Sandy Bridge, as we had also found was the case for previous generations of Intel graphics. Committed to the Mesa mainline Git repository this week though was a very important Sandy Bridge change. While the commit only touched 13 lines of code (11 lines of new code, 2 lines of changed code), it has dramatically improved the Sandy Bridge Linux performance as our results show in this article."
