rtm	46bbd72f3e	no more recursive locks ... wakeup1() assumes you hold proc_table_lock sleep(chan, lock) provides atomic sleep-and-release to wait for condition ugly code in swtch/scheduler to implement new sleep fix lots of bugs in pipes, wait, and exit fix bugs if timer interrupt goes off in schedule() console locks per line, not per byte	2006-07-15 12:03:57 +00:00
rtm	8148b6ee53	i think my cmpxchg use was wrong in acquire ... nesting cli/sti: release shouldn't always enable interrupts separate setup of lapic from starting of other cpus, so cpu() works earlier flag to disable locking in console output make locks work even when curproc==0 (still crashes in clock interrupt)	2006-07-12 11:15:38 +00:00
rtm	664324745e	cvs add spinlock.h ... fix race in schedule()	2006-07-12 09:10:25 +00:00
