From a7a8bac81f171b93c4770f51c694b15c84a2f9f8 Mon Sep 17 00:00:00 2001 From: jeff Date: Fri, 1 Jun 2007 01:12:45 +0000 Subject: - Move rusage from being per-process in struct pstats to per-thread in td_ru. This removes the requirement for per-process synchronization in statclock() and mi_switch(). This was previously supported by sched_lock which is going away. All modifications to rusage are now done in the context of the owning thread. reads proceed without locks. - Aggregate exiting threads rusage in thread_exit() such that the exiting thread's rusage is not lost. - Provide a new routine, rufetch() to fetch an aggregate of all rusage structures from all threads in a process. This routine must be used in any place requiring a rusage from a process prior to it's exit. The exited process's rusage is still available via p_ru. - Aggregate tick statistics only on demand via rufetch() or when a thread exits. Tick statistics are kept in the thread and protected by sched_lock until it exits.
