rsc 4ed974f5ea more name cleanup 2006-07-16 02:04:58 +00:00
rsc 6f2b626d28 remove non-idiomatic increment/decrement 2006-07-16 01:52:22 +00:00
rsc 51716a869c Rename fd_reference to more suggestive fd_incref.
(Fd_reference sounds like it might just return the ref count.)
2006-07-16 01:49:03 +00:00
rsc 856e1fc1ad Attempt to clean up newproc somewhat.
Also remove all calls to memcpy in favor of
memmove, which has defined semantics when
the ranges overlap.  The fact that memcpy was
working in console.c to scroll the screen is not
guaranteed by all implementations.
2006-07-16 01:47:40 +00:00
rsc 65bd8e139a New scheduler.
Removed cli and sti stack in favor of tracking
number of locks held on each CPU and explicit
conditionals in spinlock.c.

rsc 7f419a0d29 Change fetchint, fetcharg, and putint to return -1 on error, 0 on success.
They had been returning 0 on error, 1 on success, but all the callers
were checking for return value < 0.
2006-07-15 17:13:56 +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
