| 2006-08-24 | user-level malloc (untested) | kaashoek | 1 | -4/+5 | |
| nit in sbrk indirect block fix dup to share fd struct | |||||
| 2006-08-23 | i/o redirection in sh | kaashoek | 1 | -0/+18 | |
| better parsing of sh commands (copied from jos sh) cat: read from 1 if no args sbrk system call, but untested getpid system call moved locks in keyboard intr, but why do we get intr w. null characters from keyboard? | |||||
| 2006-08-19 | chdir | kaashoek | 1 | -2/+2 | |
| cd in shell nits in mkdir, ls, etc. | |||||
| 2006-08-15 | no more proc[] entry per cpu for idle loop | rtm | 1 | -39/+30 | |
| 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 | commented out code for cwd | kaashoek | 1 | -0/+3 | |
| 2006-08-13 | link() | rtm | 1 | -3/+0 | |
| 2006-08-10 | interrupts could be recursive since lapic_eoi() called before rti | rtm | 1 | -2/+14 | |
| so fast interrupts overflow the kernel stack fix: cli() before lapic_eoi() | |||||
| 2006-08-08 | fix race in holding() check in acquire() | rtm | 1 | -4/+6 | |
| 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 | 1 | -2/+4 | |
| 2006-07-27 | primitive exec | rtm | 1 | -0/+3 | |
| 2006-07-18 | prevent longjmp / forkret from writing over tf->edi | rtm | 1 | -1/+1 | |
| 2006-07-17 | add ide_lock for sleep | rsc | 1 | -0/+12 | |
| 2006-07-17 | standarize on unix-like lowercase struct names | rsc | 1 | -3/+3 | |
| 2006-07-17 | add uint and standardize on typedefs instead of unsigned | rsc | 1 | -6/+6 | |
| 2006-07-17 | goodbye PushRegs | rsc | 1 | -1/+1 | |
| 2006-07-17 | nitpicks | rsc | 1 | -1/+1 | |
| 2006-07-16 | Eliminate annoying Pseudodesc structure. | rsc | 1 | -4/+3 | |
| Eliminate unnecessary parts of mmu.h. | |||||
| 2006-07-16 | standardize on not using foo_ prefix in struct foo | rsc | 1 | -11/+11 | |
| 2006-07-16 | Rename fd_reference to more suggestive fd_incref. | rsc | 1 | -1/+1 | |
| (Fd_reference sounds like it might just return the ref count.) | |||||
| 2006-07-16 | Attempt to clean up newproc somewhat. | rsc | 1 | -51/+67 | |
| 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 | New scheduler. | rsc | 1 | -153/+168 | |
| Removed cli and sti stack in favor of tracking number of locks held on each CPU and explicit conditionals in spinlock.c. | |||||
| 2006-07-15 | move everything having to do with proc_table_lock into proc.c | rsc | 1 | -0/+50 | |
| 2006-07-15 | no more recursive locks | rtm | 1 | -23/+52 | |
| 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 | passes both usertests | rtm | 1 | -8/+10 | |
| exit had acquire where I meant release swtch now checks that you hold no locks | |||||
| 2006-07-12 | i think my cmpxchg use was wrong in acquire | rtm | 1 | -2/+23 | |
| 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 | 1 | -1/+2 | |
| fix race in schedule() | |||||
| 2006-07-12 | no more big kernel lock | rtm | 1 | -21/+46 | |
| succeeds at usertests.c pipe test | |||||
| 2006-07-11 | pre-empt both user and kernel, in clock interrupt | rtm | 1 | -0/+42 | |
| usertest.c tests pre-emption kill() | |||||
