Subject: [PATCH 0/6] more perf_counter stuff
Date: Thursday 2nd April 2009 09:11:58 UTC (over 7 years ago)
This patch set implements some features requested by Paul/Corey. The main one being the singleshot thing, which is still RFC due to being incomplete. It really needs a mechanism to run bits in a regular context ASAP after the event context. My faviourite is a self-IPI, because one can issue it from NMI context, or IRQ-disabled rq->lock context and have it work as expected. I'll look at doing a x86 self-IPI.
