Subject: 3 further range-hrtimer patches
Date: Wed, 10 Sep 2008 20:28:03 -0700 [thread overview]
Message-ID: <20080910202803.42b5f251@infradead.org> (raw)
Hi,
as reply to this email I have 3 further patches for the range-hrtimer
patchkit:
Patch 1 and 2 change the futex and nanosleep code to also use
range-hrtimers with the per process slack
Patch 3 adds a "peek-a-timer" capability; this is used from the cpuidle
loop to run any soft-expired timers just before looking at how long
we'll be idle (for determining the C-state etc); that way we'll have a
longer idle period.
I'll add these patches to the git tree in a day or two, adjusted for
comments based on this posting
