5bf11c50b5 Get rid of the blank page in picirq.c. It misaligs things now. 2010-09-02 18:36:06 -04:00
Austin Clements
79cd8b3eed Simplify allocuvm/deallocuvm to operate in a contiguous memory model. This 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 18:28:36 -04:00

f25a3f9a41 Rearrange vm.c so it's in logical order and prints nicely. Shorten a few functions in uninteresting ways to make them fit. 2010-09-02 16:23:15 -04:00

f53e6110be Simplify inituvm and userinit by assuming initcode fits on a page 2010-09-02 15:42:25 -04:00

c7c21467c3 Oops. Broke the build when I rearranged proc.c 2010-09-02 14:30:06 -04:00

d599aa2e40 Remove unused nop_pause function. 2010-09-02 14:08:45 -04:00

d8828817d7 Rearrange proc.h and proc.c to get our action-packed spreads back (mostly). They also make sense in this order, so it's not just for page layout. 2010-09-02 04:15:17 -04:00
Austin Clements
dd3ecd42cd Re-re-arrange bootasm and bootother. We can't get bootasm and bootmain on the same page, but this will make them easier to flip between. 2010-09-02 04:06:35 -04:00
Austin Clements
d2c7f64978 I totally misunderstood the even/odd spec. Add some docs, remove my 'left+' hack, and orthogonalize left/right versus even/odd so you can specify them independently. 2010-09-02 04:03:42 -04:00
Austin Clements
9d7a63e073 Specify in runoff.spec which side sheet 1 is on, since it keeps changing 2010-09-02 03:57:20 -04:00

0fa1ab632f Pack five columns into cross-ref. This saves us an entire page and fixes the single dangling line. 2010-09-02 03:56:36 -04:00

1280d26802 Oops, missed a comment about the stack guard 2010-09-02 03:36:39 -04:00
Austin Clements
4d245c79f9 Add Nickolai and myself and scrunch two lines out of the text elsewhere 2010-09-02 03:25:33 -04:00

d3ecf3eb44 Slight simplification of copyuvm. We could simplify other things now that processes are contiguous, but we'd have to think harder about the error paths. 2010-09-01 17:14:58 -04:00
Austin Clements
b1d41d6788 Remove the stack guard page. Processes are now contiguous from 0 to proc->sz, which means our syscall argument validation is correct. Add a pointer validation test and remove the stack test, which tested for the guard page. 2010-09-01 16:46:37 -04:00

87b2099ae4 Our proc.c alignment is perfect. Since ksegment/usegment went away, we get a column back, so we get our two action-packed spreads. 2010-08-31 17:49:47 -04:00

6a6bf37c3c Swap bootmain.c and bootother.S. This puts the whole boot process on one spread, though it separates the two asm files. 2010-08-31 17:35:17 -04:00

29c054df81 We don't use lesp/lebp and using them at all from C would be fraught with peril. Keep resp/rebp, but fix their code style. 2010-08-31 17:07:54 -04:00

8d774afb2d no more pminit, or ELF header at 0x10000 
kinit() knows about end and PHYSTOP
map all of kernel read/write (rather than r/o instructions)
