• 40fcfc872   [PATCH] HZ: 300Hz support ... Browse Code »

  Fix two things. Firstly the unit is "Hz" not "HZ". Secondly it is useful
  to have 300Hz support when doing multimedia work. 250 is fine for us in
  Europe but the US frame rate is 30fps (29.99 blah for pedants). 300 gives
  us a tick divisible by both 25 and 30, and for interlace work 50 and 60.
  It's also giving similar performance to 250Hz.

  I'd argue we should remove 250 and add 300, but that might be excess
  disruption for now.

  Make the timer frequency selectable. The timer interrupt may cause bus
  and memory contention in large NUMA systems since the interrupt occurs
  on each processor HZ times per second.
