cd in shell
nits in mkdir, ls, etc.

rtm 350e63f7a9 no more proc[] entry per cpu for idle loop
each cpu[] has its own gdt and tss
no per-proc gdt or tss, re-write cpu's in scheduler (you win, cliff)
main0() switches to cpu[0].mpstack
2006-08-15 22:18:20 +00:00
rtm 211ff0c67e namei returns locked parent dir inode for create / unlink
don't hold fd table lock across idecref() (latter does block i/o)
idecref calls iput() in case last ref -> freeing inode
dir size is 512 * # blocks, so readi/writei &c work
unlink deletes dirent even if ip->nlink > 0

rsc 9b37d1bfaa Add user.h for prototypes.
Add cons_puts for cleaner output.
2006-07-16 15:36:31 +00:00
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 6eb6f10c56 passes both usertests
exit had acquire where I meant release
swtch now checks that you hold no locks
2006-07-12 15:35:33 +00:00
rtm 664324745e cvs add spinlock.h
fix race in schedule()

rtm b548df152b pre-empt both user and kernel, in clock interrupt
usertest.c tests pre-emption
kill()
2006-07-11 17:39:45 +00:00
rtm 8b4e2a08fe swtch saves callee-saved registers
swtch idles on per-CPU stack, not on calling process's stack
fix pipe bugs
usertest.c tests pipes, fork, exit, close
2006-07-01 21:26:01 +00:00
