Kernels 3.11 and 3.12 include (very good) power management for OSS radeon driver. It's not enabled by default though. Use radeon.dpm=1 kernel parameter. You need whatever_dpm.bin microcode (firmware) for your model for dpm to work though. -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
