2017-08-29 | fix runoff complaints about pagination and long lines | Robert Morris | 1 | -2/+2 | |
2017-02-01 | A tiny bit of clean up (e.g., move code searching cpu array from lapic.c into | Frans Kaashoek | 1 | -2/+13 | |
mycpu() in proc.c. | |||||
2017-02-01 | use panic | Frans Kaashoek | 1 | -6/+2 | |
2017-02-01 | shorten comment | Frans Kaashoek | 1 | -6/+2 | |
2017-02-01 | Eliminate code for gs trick to track per-cpu state. We rely on lapiccpunum() | Frans Kaashoek | 1 | -11/+23 | |
to find a per-cpu id with which we locate a cpu's cpu struct. | |||||
2017-01-31 | Read curproc from cpu structure, but be careful because after a schedule event | Frans Kaashoek | 1 | -38/+63 | |
myproc() points to a different thread. myproc(); sched(); myproc(); // this proc maybe different than the one before sched Thus, in a function that operates on one thread better to retrieve the current process once at the start of the function. | |||||
2017-01-31 | Start of an experiment to remove the use of gs for cpu local variables. | Frans Kaashoek | 1 | -40/+49 | |
2016-09-15 | change allocproc() back to acquiring the ptable.lock. | Robert Morris | 1 | -14/+6 | |
fix bugs where caller incorrectly released lock on error return path. | |||||
2016-09-08 | this might fix the reported deadlock, though I can't reproduce it. | Robert Morris | 1 | -1/+17 | |
2016-09-02 | comment about sched() saving/restoring cpu->intena | Robert Morris | 1 | -1/+6 | |
2016-08-25 | Remove trailing white space with: | Frans Kaashoek | 1 | -9/+9 | |
for f in *.{h,c}; do sed -i .sed 's/[[:blank:]]*$//' $f; done (Thanks to Nicolás Wolovick) | |||||
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. | |||||
2014-08-27 | a start at concurrent FS system calls | Robert Morris | 1 | -2/+2 | |
2014-08-04 | every iput() and namei() must be inside a transaction | Robert Morris | 1 | -0/+2 | |
2014-08-04 | use acquire/release to force order for pid=np->pid;np->state=RUNNING | Robert Morris | 1 | -3/+7 | |
for bug reported by symingz@gmail.com and cs1100254@cse.iitd.ernet.in | |||||
2012-08-22 | Remove unused argument to setupkvm (thanks to Peter Froehlich) | Frans Kaashoek | 1 | -1/+1 | |
2011-09-01 | fix usertests to correctly test what happens when you call | Robert Morris | 1 | -1/+1 | |
exec() with arguments that don't fit on a single page. | |||||
2011-08-22 | A comment | Frans Kaashoek | 1 | -0/+3 | |
2011-08-22 | Remove sys_init syscall | Frans Kaashoek | 1 | -0/+6 | |
Invoke initlog from forkret on first user process | |||||
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) | |||||
2011-07-29 | Map kernel high | Frans Kaashoek | 1 | -0/+1 | |
Very important to give qemu memory through PHYSTOP :( | |||||
2011-02-19 | xv6: formatting, cleanup, rev5 (take 2) | Russ Cox | 1 | -38/+38 | |
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. | |||||
2010-09-01 | Space police | Austin Clements | 1 | -5/+5 | |
2010-08-31 | Fix too-long lines | Austin Clements | 1 | -1/+2 | |

fix corner cases with alignment when mapping kernel ELF file | |||||
2010-07-25 | some cleanup | Frans Kaashoek | 1 | -1/+1 | |
2010-07-23 | Checkpoint page-table version for SMP | Frans Kaashoek | 1 | -0/+1 | |

2009-09-02 | can set just %gs now. | Russ Cox | 1 | -2/+1 | |
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 | |

2009-08-08 | shuffle and tweak for formatting. | Russ Cox | 1 | -102/+104 | |
pdf has very good page breaks now. would be a good copy for fall 2009. | |||||
