Follow-up Comment #12, bug #28169 (project gnewsense): I've optimized pixman quite a bit with Loongson's multimedia instructions, using the existing MMX code. See http://mattst88.com/blog/2012/05/17/Optimizing_pixman_for_Loongson:_Process_and_Results/ They're available in pixman-0.25.6 and will be in the pixman-0.26.0 stable release. Further optimization work includes - Bilinear/nearest scaling compositing functions for pixman, which are *really* important for Firefox performance - Optimized xf86XVCopyPacked for Xv performance. Really, I think pixman should grow support for all these YUV-type formats, and the code in the X server should go away - There may be some way to improve XAA performance that's regressed a lot in the last few years, but I don't know if this is doable Then, there's the work of simply getting the upstream X server working on the Yeeloong.. It would help me if someone could tell me what the differences are between the upstream 1.7.6 siliconmotion driver and the 2.2.8 version -- and why the changes in the 2.2.8 driver aren't upstream? _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/bugs/?28169> _______________________________________________ Message sent via/by Savannah http://savannah.nongnu.org/
