Age	Commit message (Collapse)	Author
2006-09-07	more comments	rsc

2006-08-29	clean up stale error checks and panics	rtm
	delete unused functions a few comments
2006-08-10	interrupts could be recursive since lapic_eoi() called before rti	rtm
	so fast interrupts overflow the kernel stack fix: cli() before lapic_eoi()
2006-08-08	fix race in holding() check in acquire()	rtm
	give cpu1 a TSS and gdt for when it enters scheduler() and a pseudo proc[] entry for each cpu cpu0 waits for each other cpu to start up read() for files
2006-07-29	open()	rtm

2006-07-20	uint32_t -> uint &c	rtm

2006-07-17	add ide_lock for sleep	rsc

2006-07-17	add uint and standardize on typedefs instead of unsigned	rsc

2006-07-15	no more recursive locks	rtm
	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
2006-07-12	i think my cmpxchg use was wrong in acquire	rtm
	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	cvs add spinlock.h	rtm
	fix race in schedule()
