2002-09-17Work around a vax-specific problem where mmap()ing large amount of memoryMiod Vallat
would cause a panic. To do so, instead of panic'ing in pmap_protect() if the pages which are supposed to be used for the mapping are out of the affordable pmap limits, just return, and handle this in pmap_enter, by either returning EFAULT if pmap_enter has been invoked with PMAP_CANFAIL, or panicing there if there is no escape. ok art@
2002-09-17I sense too much cut 'n paste.Artur Grabowski
Allow this to build with DEBUG.
2002-09-17handle fpu exceptions properly, might use a regress, i guessMichael Shalayeff
2002-09-17Until vgafb on macppc properly support non-console operation, doDale Rahn
not allow it to execute code which could panic the otherwise booting system.
2002-09-17Switch device register routine from last match to first match. FixesHugh Graham
problems one of my machines was having with phantom scsi luns and no way to discern which one was the boot device.

2002-09-12Change the PMAP_PAGEIDLEZERO api to take the struct vm_page instead of the pa.Artur Grabowski
2002-09-12Change the PMAP_{MAP,UNMAP}_POOLPAGE api to take a vm_page as argumentArtur Grabowski
and return a VM_PAGE. This is to allow sparc64 to cheaply record the VAC color for those pages.

2002-09-11Some early callers of pmap_growkernel call it before vm_page structuresArtur Grabowski
are initialized. So we can't to PHYS_TO_VM_PAGE becuase there are no vm_pages. Reintroduce the old pmap_zero_page renamed to pmap_zero_phys that can zero pages without struct vm_page.
2002-09-11Include zstty.h, so that the NZSTTY check will be correct.Dale Rahn
2002-09-11When freeing the extent, include the page offset, not just the pageDale Rahn
base. This is important when allocating/freeing sub page size mappings.

-fix several stupid bugs -get encoding setup correct -add support for capture
2002-09-10copy syscall args in the syscall() based on theMichael Shalayeff
amount given in the sysent. deal w/ the words swappage phenomena due to reverse long word storage on the stack and that being reverse copied by words yielding long word being word swapped. do it only for syscall(2) and __syscall(2) since that's how those w/ long word args syscalls get used (for proper alignment). discussed and ideas from: deraadt@, drahn@ and fredette@ note: this might be a good point for a regress.

2002-09-10rework the fpu csw a bit better and move non-trap related stuff to laterMichael Shalayeff
2002-09-10Change the pmap_zero_page and pmap_copy_page API to take the struct vm_page *Artur Grabowski
instead of the pa. Most callers already had it handy and those who didn't only called it for managed pages and were outside time-critical code. This will allow us to make those functions clean and fast on sparc and sparc64 letting us to avoid unnecessary cache flushes. deraadt@ miod@ drahn@ ok.

has been replaced with a serial port adapter on any machine that has a real serial port internally. This will also power on the internal modem for keylargo based machines (tested on original PBG4) when the serial port is open. ok miod@
