Subject: [PATCH 00/11] generic software counters -v2
Date: Friday 13th March 2009 11:21:25 UTC (over 7 years ago)
This patch set improves the current software counters by providing sampling events for most of them. The clock based software counters use hrtimers to generate events, allowing sample based profiling without hardware support -- obviously this has limited functionality for kernal based profiling since we disable interrupts quite frequently, but should be good for userspace. Other events like pagefaults insert simple hooks into the actual pagefault code to generate these events. Future work (in-progress) will hook into the tracepoint infrastructure to to provide profiling events.
