| 2003-05-13 | The sab driver sometimes gets out of sync with the hardware. This can | Henric Jungheim | |
| cause the serial console to hang. ok jason@ | |||
| 2003-05-13 | Add option NO_PROPOLICE, which explicitely disables the use of the propolice | Miod Vallat | |
| stack protection when building kernels. Intended to be used on installation media, with tight space constraints - currently, only added where SMALL_KERNEL was already defined. Not thoroughly tested, but requested by deraadt. | |||

| 2003-05-13 | The current solution to handle the protection fault trap is not | Artur Grabowski | |
| correct. It breaks down if we're trying to jump through a function pointer. The protection fault trap on i386 must be one of the most braindead traps ever invented in the history of humankind. It doesn't give you any information about what went wrong except the instruction that faulted. Since the problem we're trying to deal with is a segmentation problem, we don't get the desitination that we want to jump to, we just get the instruction and we won't add a disassembler to trap handling just to try to figure out what went wrong. What we want to do is to handle this as a normal fault to let noexec accounting in pmap_enter deal with the changes to the code segment. Unfortunately that's impossible. We don't know the faulting address, so we need to change how the exec accounting works. Basically the code segment must already cover the address we want to execute before we can fault it in. New scheme: o Start with conservative code segment. o If we get a protection fault, go through all mappings in the process and find the highest executable mapping, fix up the code segment and record that address. If the code segment didn't change, the protection fault wasn't fixable - just die. o If the highest executable mapping is removed, just reset the code segment to something conservative and let the next protection fault deal with it. We can't read all the vm mappings of the process from the pmap because of locking hell. This should allow floating code segment whenever someone implements that. Also, fix the pmap_protect function to behave more like the other pmaps we have and be slightly more agressive to force more proper protection changes. ok:ed by various people. | |||

| 2003-05-13 | nuke curproc common (yes this will need revisiting in smp land, but what | Jason Wright | |

| 2003-05-12 | use new display types | Jason Wright | |
| 2003-05-12 | Initial work to bring this driver in par with other sparc frame buffers: | Miod Vallat | |
| - do not reprogram the colormap to black and white, after programming the rasops one (oops). This gives us back a black on white display with colour support. - if the screen resolution would cause the switch from the prom font to a reasonably sized wsfont to leave text in the margins, clear the screen (cut and paste from similar code in vigra.c) - try and use more symbolic constants rather than magical values all over the place. Thanks to millert@ for bringing a sparcbook here. | |||
