  • 51716a869c Rename fd_reference to more suggestive fd_incref. (Fd_reference sounds like it might just return the ref count.) rsc 2006-07-16 01:49:03 +0000

  • 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. rsc 2006-07-15 17:13:56 +0000
  • 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 rtm 2006-07-15 12:03:57 +0000

  • 6eb6f10c56 passes both usertests exit had acquire where I meant release swtch now checks that you hold no locks rtm 2006-07-12 15:35:33 +0000
  • 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) rtm 2006-07-12 11:15:38 +0000

  • 5ce9751cab Changes to allow use of native x86 ELF compilers, which on my Linux 2.4 box using gcc 3.4.6 don't seem to follow the same conventions as the i386-jos-elf-gcc compilers. Can run make 'TOOLPREFIX=' or edit the Makefile. rsc 2006-07-11 01:07:40 +0000
