* Add scaled time to taskstats based process accountingMichael Neuling2007-10-181-0/+2
| | | | | | | | | | | | | | | | This adds items to the taststats struct to account for user and system time based on scaling the CPU frequency and instruction issue rates. Adds account_(user|system)_time_scaled callbacks which architectures can use to account for time using this mechanism.

* sched: guest CPU accounting: add guest-CPU /proc/stat fieldLaurent Vivier2007-10-151-0/+1
| | | | | | | | | | | as recent CPUs introduce a third running state, after "user" and "system", we need a new field, "guest", in cpustat to store the time used by the CPU to run virtual CPU. Modify /proc/stat to display this new field. Signed-off-by: Laurent Vivier <Laurent.Vivier@bull.net> Acked-by: Avi Kivity <avi@qumranet.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
