Since they happen immediately before the thread is placed on a run queue they would normally dwarf the more informative preemption or yield event and it is implicitly understood that a thread is back on the run queue as part of these events. - Call self.checkstamp() in the cpu load parsing functions in case the 2004-12-26T02:02:34Z Jeff Roberson jeff@FreeBSD.org 2004-12-26T02:02:34Z urn:sha1:b0e485185fddd6ee87d332b4d260e6fec31c902b timestamp has wrapped. - The regexp for the load should have been (/d+), fix this so loads over 9 2004-12-26T01:18:49Z Jeff Roberson jeff@FreeBSD.org 2004-12-26T01:18:49Z urn:sha1:3e16b3e04f49a293c41e120417403220537992e6 are properly represented. - Add 'schedgraph' a scheduler trace visualization tool written with 2004-12-26T00:13:07Z Jeff Roberson jeff@FreeBSD.org 2004-12-26T00:13:07Z urn:sha1:dcee3bd3124118af92913daed08cdfcc2a06ed58 python and tkinter. Schedgraph takes input from files produces by ktrdump -ct when KTR_SCHED is compiled into the kernel. The output represents the states of each thread with colored line segments as well as colored points for non-state scheduler events. Each line segment and point is clickable to obtain extra detail.
