| 2016-09-11 | Move retry loop/sleep/wakeup in bio.c into sleeping locks | Frans Kaashoek | 1 | -1/+1 | |
| 2016-09-11 | Straight replacement of B_BUSY with a sleeping lock. | Frans Kaashoek | 1 | -0/+7 | |
| 2016-08-18 | Removed useless function and prototypes. | Peter H. Froehlich | 1 | -4/+0 | |
| 2015-06-27 | Pick up where i left off in april: | Frans Kaashoek | 1 | -2/+2 | |
| - move log into metadata part of disk, so that marking that the log's blocks are in use falls out for free - superblock describes the whole disk (sizes and offets) - sizes and offsets are computed in one place (mkfs) and the rest of the code refers to the superblock for these values, instead of recomputing them. | |||||
| 2014-09-12 | cmosgetdate() for system-call homework | Cody Cutler | 1 | -0/+2 | |
| the day of reckoning has come for the debug port "Shutdown" hack. instead of mucking with ACPI or using a new hack, the student will now write sys_date() using the cmosgetdate() helper. | |||||

| 2012-08-22 | Merge branch 'master' of git+ssh://amsterdam.csail.mit.edu/home/am0/6.828/xv6 | Frans Kaashoek | 1 | -2/+2 | |

| 2012-08-22 | Remove unused argument from lapicinit (thanks to Peter Froehlich) | Frans Kaashoek | 1 | -1/+1 | |
| 2012-02-17 | Make fetchint and fetchstr use proc instead of taking a struct proc | Austin Clements | 1 | -2/+2 | |
| Previously, these were inconsistent: they used their struct proc argument for bounds checking, but always copied the argument from the current address space (and hence the current process). Drop the struct proc argument and always use the current proc. Suggested by Carmi Merimovich. | |||||
| 2011-09-13 | eliminate enter_alloc -- use kalloc for everything | Robert Morris | 1 | -4/+3 | |

| 2011-08-29 | Revert "Introduce and use sleeplocks instead of BUSY flags" | Frans Kaashoek | 1 | -5/+0 | |
| My changes have a race with re-used bufs and the code doesn't seem to get shorter Keep the changes that fixed ip->off race This reverts commit 3a5fa7ed9020eaf8ab843a16d26db7393b2ec072. Conflicts: defs.h file.c file.h | |||||

| 2011-08-26 | Introduce and use sleeplocks instead of BUSY flags | Frans Kaashoek | 1 | -0/+5 | |
| Remove I_BUSY, B_BUSY, and intrans defs and usages One spinlock per buf to avoid ugly loop in bget fix race in filewrite (don't update f->off after releasing lock) | |||||
| 2011-08-16 | Clean up memlayout.h | Frans Kaashoek | 1 | -0/+1 | |
| Get rid of last instances of linear address and "la" Get ready for detecting physical memory dynamically | |||||

| 2010-09-02 | Simplify allocuvm/deallocuvm to operate in a contiguous memory model. This ↵ | Austin Clements | 1 | -2/+2 | |
| makes their interface match up better with proc->sz and also simplifies the callers (it even gets the main body of exec on one page). | |||||
