2006-09-07 | refactor syscall code | rsc | 1 | -6/+5 | |
2006-09-07 | run without lapic and ioapic, if they are not present | kaashoek | 1 | -0/+6 | |
if no lapic available, use 8253pit for clock now xv6 runs both on qemu (uniprocessor) and bochs (uniprocessor and MP) | |||||
2006-09-06 | fd.c -> file.c | rsc | 1 | -1/+1 | |
2006-09-06 | fd_* => file_* | rsc | 1 | -8/+8 | |
2006-09-06 | struct fd -> struct file | rsc | 1 | -8/+8 | |

2006-08-30 | complain if no disk 1 | rtm | 1 | -0/+1 | |
lots of cleanup | |||||
2006-08-29 | i broke sbrk, fix it | rtm | 1 | -1/+1 | |
2006-08-29 | clean up stale error checks and panics | rtm | 1 | -1/+1 | |
delete unused functions a few comments | |||||

fix race in mknod / creat use last component in dirent in mknod, not path | |||||
2006-08-24 | user-level malloc (untested) | kaashoek | 1 | -1/+1 | |
nit in sbrk indirect block fix dup to share fd struct | |||||
2006-08-23 | i/o redirection in sh | kaashoek | 1 | -0/+1 | |
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? | |||||
2006-08-20 | compiling, but untested dup | kaashoek | 1 | -1/+0 | |
2006-08-20 | removed block system call | kaashoek | 1 | -0/+1 | |
renumber system calls (run gmake clean!) skeleton for dup system call | |||||
2006-08-15 | commented out code for cwd | kaashoek | 1 | -0/+2 | |
2006-08-13 | namei returns locked parent dir inode for create / unlink | rtm | 1 | -1/+1 | |
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 | |||||
2006-08-13 | link() | rtm | 1 | -0/+1 | |
2006-08-12 | zero out all of dirent.name when creating | rtm | 1 | -1/+1 | |
don't increase length of directory | |||||
2006-08-12 | fix getblk to actually lock the block | rtm | 1 | -1/+1 | |
no more cons_put system calls usertests tests two processes writing files | |||||
2006-08-12 | fstat | kaashoek | 1 | -0/+3 | |
primitive ls | |||||
2006-08-12 | unlink,mknod,create with multi-component pathnames should work now | kaashoek | 1 | -2/+2 | |
remove console init code from userfs | |||||
2006-08-11 | fix deadlock---iput(dp) asap | kaashoek | 1 | -0/+1 | |
working unlink, but doesn't free dir blocks that become empty remove out-of-date comment in ioapic | |||||
2006-08-11 | init creates console, opens 0/1/2, runs sh | rtm | 1 | -2/+3 | |
sh accepts 0-argument commands (like userfs) reads from console | |||||
2006-08-10 | interrupts could be recursive since lapic_eoi() called before rti | rtm | 1 | -0/+5 | |
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 | 1 | -0/+2 | |
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... | |||||
2006-08-10 | printf | kaashoek | 1 | -1/+1 | |
convert userfs to use printf bfree ifree writei start on unlink | |||||
2006-08-09 | devsw | kaashoek | 1 | -0/+1 | |
checkpoint: write(fd,"hello\n",6) where fd is a console dev almost works | |||||
2006-08-08 | mknod,ialloc,iupdate | kaashoek | 1 | -0/+1 | |
2006-08-07 | bwrite | kaashoek | 1 | -0/+2 | |
2006-08-06 | generalize async read to support write too | kaashoek | 1 | -2/+2 | |
2006-08-04 | nit | kaashoek | 1 | -2/+0 | |
2006-08-04 | better interrupt plan---this one appears to work | kaashoek | 1 | -0/+6 | |
ioapic | |||||

2006-07-21 | bread | rtm | 1 | -1/+9 | |
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 | 1 | -6/+6 | |
2006-07-17 | add ide_lock for sleep | rsc | 1 | -4/+3 | |
2006-07-17 | no more cons_putc; real_cons_putc -> cons_putc | rsc | 1 | -1/+0 | |
2006-07-17 | add uint and standardize on typedefs instead of unsigned | rsc | 1 | -6/+6 | |
2006-07-17 | nitpicks | rsc | 1 | -2/+2 | |
2006-07-16 | standardize on not using foo_ prefix in struct foo | rsc | 1 | -0/+2 | |
2006-07-16 | remove acquire1 and release1 | rsc | 1 | -2/+0 | |
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 | -2/+2 | |
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 | -3/+0 | |
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/+2 | |
2006-07-15 | no more recursive locks | rtm | 1 | -1/+4 | |
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 |
