Modified Files: xsrc/external/mit/xf86-video-openchrome/dist/src: via_memcpy.c Log Message: Remove a couple '#ifdef linux's to let the driver use optimized memcpy functions on NetBSD for video copy. Gives nearly 2x performance on my test system (previously "kernel" memcpy was always used): CHROME(0): Benchmarking video copy. Less time is better. CHROME(0): Timed libc YUV420 copy... 3000272. Throughput: 315.6 MiB/s. CHROME(0): Timed kernel YUV420 copy... 3024946. Throughput: 313.0 MiB/s. CHROME(0): Timed SSE YUV420 copy... 1591352. Throughput: 595.0 MiB/s. CHROME(0): Timed MMX YUV420 copy... 2566279. Throughput: 369.0 MiB/s. CHROME(0): Ditching 3DNow! YUV420 copy. Not supported by CPU. CHROME(0): Timed MMX2 YUV420 copy... 1696662.
