High Resolution Timer

TOP del.icio.us

If you’re planning on using rosegarden, when you recompile your kernel you’ll want to make sure the following options are set like this in your .config:

# CONFIG_HZ_100 is not set
# CONFIG_HZ_250 is not set
CONFIG_HZ_1000=y
CONFIG_HZ=1000

Doing this got rid of a start-up warning from rosegarden that told me I didn’t have a high enough resolution system timer to really work with MIDI. The Fedora Core 6 stock kernel seems to keep time at 250Hz, which is not fast enough for rosegarden.
