| 2016-08-13 | hold ptable.lock for the entire process creation | Robert Morris | 1 | -7/+13 | |
| however, processes still modify their own p->* without locking | |||||
| 2016-08-11 | nothing much | Robert Morris | 1 | -1/+1 | |
| 2015-06-27 | Pick up where i left off in april: | Frans Kaashoek | 1 | -1/+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. | |||||

| 2011-08-09 | Use static page table for boot, mapping first 4Mbyte; no more segment trick | Frans Kaashoek | 1 | -1/+1 | |
| Allocate proper kernel page table immediately in main using boot allocator Remove pginit Simplify address space layout a tiny bit More to come (e.g., superpages to simplify static table) | |||||

| 2011-01-11 | make new code like old code | Russ Cox | 1 | -5/+7 | |
| Variable declarations at top of function, separate from initialization. Use == 0 instead of ! for checking pointers. Consistent spacing around {, *, casts. Declare 0-parameter functions as (void) not (). Integer valued functions return -1 on failure, 0 on success. | |||||
| 2010-09-13 | change some comments, maybe more informative | Robert Morris | 1 | -2/+4 | |
| delete most comments from bootother.S (since copy of bootasm.S) ksegment() -> seginit() move more stuff from main() to mainc() | |||||
| 2010-09-02 | Simplify allocuvm/deallocuvm to operate in a contiguous memory model. This ↵ | Austin Clements | 1 | -3/+4 | |
| 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). | |||||
| 2010-09-02 | Simplify inituvm and userinit by assuming initcode fits on a page | Austin Clements | 1 | -5/+2 | |
| 2010-09-02 | Oops. Broke the build when I rearranged proc.c | Austin Clements | 1 | -0/+2 | |
| 2010-09-02 | Rearrange proc.h and proc.c to get our action-packed spreads back (mostly). ↵ | Austin Clements | 1 | -86/+86 | |
| They also make sense in this order, so it's not just for page layout. | |||||

| 2009-09-02 | another attempt at cpu-local variables. | Russ Cox | 1 | -2/+1 | |
| this time do it ourselves instead of piggybacking on TLS. add -fno-pic to Makefile; pic code breaks our fake TLS. | |||||
| 2009-09-02 | fix TLS again; | Russ Cox | 1 | -2/+3 | |
| still not quite but a lot better. | |||||
| 2009-09-02 | Fix TLS for PIC systems | Russ Cox | 1 | -0/+1 | |

| 2009-05-31 | move fork into proc.c | rsc | 1 | -14/+20 | |
| 2009-05-31 | Some proc cleanup, moving some of copyproc into allocproc. | rsc | 1 | -84/+82 | |
| Also, an experiment: use "thread-local" storage for c and cp instead of the #define macro for curproc[cpu()]. | |||||
