2007-08-14	formatting, sleep bug fix	rsc

2007-08-14	ide_write unused => gone	rsc

2006-09-08	move ide_intr lower	rsc

2006-09-07	fix disk bug	rsc

2006-09-07	fix ide, pit interfaces	rsc

2006-09-07	comments	rsc

2006-09-07	run without lapic and ioapic, if they are not present	kaashoek
	if no lapic available, use 8253pit for clock now xv6 runs both on qemu (uniprocessor) and bochs (uniprocessor and MP)
2006-09-06	more named constants	rsc

2006-09-06	more tabs go away	rsc

2006-09-06	no /* */ comments	rsc

2006-09-06	standardize various * conventions	rsc

2006-09-06	spacing fixes: no tabs, 2-space indents (for rtm)	rsc

2006-09-03	remove duplication	kaashoek
	don't use the same name for two different pieces of code
2006-08-30	complain if no disk 1	rtm
	lots of cleanup
2006-08-13	link()	rtm

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()
2006-08-10	low-level keyboard input (not hooked up to /dev yet)	rtm
	fix acquire() to cli() before incrementing nlock make T_SYSCALL a trap gate, not an interrupt gate sadly, various crashes if you hold down a keyboard key...
2006-08-09	iread for T_DEV	kaashoek
	O_RDWR, etc. create file
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
2006-08-07	bwrite	kaashoek

2006-08-06	generalize async read to support write too	kaashoek

2006-08-04	better interrupt plan---this one appears to work	kaashoek
	ioapic
2006-07-29	open()	rtm

2006-07-29	acquire+release ide_lock in ide_intr	kaashoek

2006-07-21	bread	rtm
	iget mkfs makes a file system image put this in your .bochsrc: ata0-slave: type=disk, mode=flat, path="fs.img", cylinders=1024, heads=1, spt=1
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
2006-07-10	queue with disk requests	kaashoek

2006-07-10	read the disk using interrupts	kaashoek

2006-07-06	disable all interrupts when acquiring lock	kaashoek
	user program that makes a blocking system call
2006-07-05	timer interrupts	kaashoek
	disk interrupts (assuming bochs has a bug)
2006-06-16	checkpoint	rtm
