If you run a make menuconfig in the kernel source, go to the menu Processor type and Features -> Timer Frequency. From there you can pick 100, 250 (the default) or 1000. I've seen several users who are playing back HDTV content say they had a huge reduction in jerky playback after changing to 1000 as well. From the help on the options you get the following: CONFIG_HZ_100: x x x x 100 HZ is a typical choice for servers, SMP and NUMA systems x x with lots of processors that may show reduced performance if x x too many timer interrupts are occurring. CONFIG_HZ_250: x x x x 250 HZ is a good compromise choice allowing server performance x x while also showing good interactive responsiveness even x x on SMP and NUMA systems. CONFIG_HZ_1000: x x x x 1000 HZ is the preferred choice for desktop systems and other x x systems requiring fast interactive responses to events. _______________________________________________ ivtv-devel mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-devel
