mmmmn 资料收集 <<<8月19日 | 首页 | 8月22，23日>>> 8月20，21日时间：2004-09-24 1、一个BUG：XVR-100使用100%的CPU，在fbpm 功能被允许的时候。这个BUG被114537-22 solais8 114537-22 solaris9所修复 2、关于进程调度 There's some confusion here, partially due to some odd bits of Solaris parlance. The "scheduler", known as PID 0, process "sched", only handles swapping whole processes to and from disk. The subsystem which handles picking which processes to run, preempting running threads, etc. is known as the "dispatcher". Note that there is no seperate "dispatcher" thread -- all the dispatcher work happens on an "as needed" basis by all the threads in the system. Threads which are in the dispatcher code cannot be preempted -- it all runs at high PIL (DISP_LEVEL, or 11), which is above LOCK_LEVEL (10), which means that the thread block or be preempted. It can be interrupted by high-level interrupts (for example, by the timer interrupt, which runs at PIL 14), but those don't change the progression. Jim Mauro's "Inside Solaris" articles (later pulled together and expanded into the "Solaris Kernel Internals" book, which is recommended reading) on the dispatcher are still reasonably accurate, even though it only talks about releases up to Solaris 7: http://sunsite.uakom.sk/sunworldonline/swol-01-1999/swol-01-insidesolaris.html http://sunsite.uakom.sk/sunworldonline/swol-02-1999/swol-02-insidesolaris.html (The details have gotten a bit more complicated in later releases, but the broad sweep is the same) http://sunsite.uakom.sk/sunworldonline/swol-12-1998/swol-12-insidesolaris.html

Verifying digital signature for signer Digital signature for signer verified. Verifying contents of signed patch </tmp/117171-08.jar> Contents of signed patch </tmp/117171-08.jar> verified.
