| 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 | 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. | |||||

| 2009-05-31 | Some proc cleanup, moving some of copyproc into allocproc. | rsc | 1 | -84/+82 | |

| timer-preempted kernel thread resumes execution in trap() after yield(). otherwise the kernel could get an arbitrary number of nested timer intrs. | |||||

| 2007-09-27 | Final word on the locking fiasco? | rsc | 1 | -4/+5 | |
| Change pushcli / popcli so that they can never turn on interrupts unexpectedly. That is, if interrupts are on, then pushcli(); popcli(); turns them off and back on, but if they are off to begin with, then pushcli(); popcli(); is a no-op. I think our fundamental mistake was having a primitive (release and then popcli nee spllo) that could turn interrupts on at unexpected moments instead of being explicit about when we want to start allowing interrupts. With the new semantics, all the manual fiddling of ncli to force interrupts off in certain sections goes away. In return, we must explicitly mark the places where we want to enable interrupts unconditionally, by calling sti(). There is only one: inside the scheduler loop. | |||||
| 2007-09-27 | yank out stack overflow checking ugliness | rsc | 1 | -5/+1 | |
| 2007-09-27 | okay, that was long enough - revert | rsc | 1 | -7/+10 | |
| 2007-09-27 | test: store curproc at top of stack | rsc | 1 | -10/+7 | |
| I don't actually think this is worthwhile, but I figured I would check it in before reverting it, so that it can be in the revision history. Pros: * curproc doesn't need to turn on/off interrupts * scheduler doesn't have to edit curproc anymore Cons: * it's ugly * all the stack computation is more complicated. * it doesn't actually simplify anything but curproc, and even curproc is harder to follow. | |||||
| 2007-09-27 | rename splhi/spllo to pushcli/popcli | rsc | 1 | -5/+5 | |
| 2007-09-27 | overkill: use segments to catch stack overflow (delete before next year) | rsc | 1 | -1/+5 | |
