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
Austin Clements 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
Austin Clements 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
Austin Clements 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

Robert Morris 3597d5dc70 oops. last minute simplicifaction to kalloc(). 2010-08-31 19:21:33 -04:00
Austin Clements 5048762c7e Page break kalloc.c 2010-08-31 17:52:03 -04:00
Austin Clements 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
Austin Clements 13b3f4d2e3 Make it possible to express half-page preferences 2010-08-31 17:46:30 -04:00
Austin Clements fd462b6a01 Got the meat of spinlocks on one spread 2010-08-31 17:40:21 -04:00
Austin Clements 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
Austin Clements c7ceb71d57 Sheet 1 is a right page now because of the (much) longer cross-ref 2010-08-31 17:33:04 -04:00
Austin Clements 51e2a7b324 print depends on runoff.spec 2010-08-31 17:30:31 -04:00
Austin Clements 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

Austin Clements 1aee6a6c4f Hopefully get the printf size spec right, regardless of compiler. 2010-08-31 16:01:38 -04:00
Robert Morris 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)
thanks, austin

Austin Clements fe4623b99c Fix for gdbstub argument change in qemu 0.11. Rename qemu-gdb-nox target to qemu-nox-gdb because you frequently want to add the gdb part, but rarely the nox part. 2010-08-30 12:22:08 -04:00
