scw 5bd17a1271 Separate out devices common to many Motorola mvme boards (68k, 88k and ppc) 
in preparation for future mvmeppc and mvme88k ports.

This needs a bit if tidying up to make it trully shareable, which will
happen as the new mvme ports are added.

kleink e5341ee40f No point in installing svr4_machdep.h. 2001-11-28 13:14:12 +00:00
soren 662f877587 MAXSLP is defined to be a machine-independent scheduling parameter, 
so move it into sys/param.h.

scw dca93f1b48 The success/failure status for some Bug syscalls is indicated by the Z 
flag in the status register, not by a value on the stack.

How this ever worked for so long is beyond me...

thorpej e727e3f180 Split elf32 vs. elf64 handling in loadfile(), including support for 
each separately and explicitly.  BOOT_ELF is now BOOT_ELF32 and
BOOT_ELF64, and ELFSIZE should no longer be defined in loadfile_machdep.h.

chris 0e7661f023 Update pmap_update to now take the updated pmap as an argument. 
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.

thorpej babefc5331 Add BUS_DMA_READ and BUS_DMA_WRITE flags, that hint the back-end 
at dmamap load time that the mapping will be used for a unidirectional
transfer of the specified direction.

scw 35110949ce Ditch the `simulated' software interrupt in favour of 
hardware-assisted soft interrupts on all boards.
(Note: VMEChip2-less 162/172 not yet tested)

This greatly simplifies the `rei' path and allows
interrupt nesting to be tracked somewhat more easily.

As a result we now have a working CLKF_INTR() macro
and can detect uvm_fault() being called from an interrupt
(although there may still be a very short race detecting
the latter; need to investigate further).

scw c22fb1db55 Finally nobble the bus_dmamap_sync() problem with osiop(4). 
Basically, bus_dmamap_sync() `PREREAD' needs to flush the cache
for the start and end of the region if it is not aligned to
a cacheline boundary, otherwise a subsequent POSTREAD can *purge*
valid data which was in the cacheline but *outside* the region
passed to bus_dmamap_sync().

Bus snooping doesn't always help here because osiop(4) calls
bus_dmamap_sync() with POSTREAD even if no data was actually
transferred! (And we can't rely on snooping on the 68060 models anyway).

thorpej cf67ac7122 Per discussion w/ chuck and chuck, restructure the md page stuff 
to use a structure called "vm_page_md", and use __HAVE_VM_PAGE_MD
and __HAVE_PMAP_PHYSSEG.
 2001-05-01 02:19:13 +00:00
thorpej 2b27ac7a99 Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for 
each vm_page structure.  Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM.  These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.

This deprecates struct pmap_physseg.  As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.

Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now).  Changes to other pmap
modules will follow.

thorpej 69abdbf60c Undo a misguided previous change to the pmap_update() API. 2001-04-22 23:19:26 +00:00
thorpej 4738622712 Give pmap_update() an argument (a pmap_t) so that it knows which 
pmap it should be updating.

thorpej 7f10ba88b1 #define away pmap_update() in <machine/pmap.h> so that no function 
call overhead is incurred as we start sprinkling pmap_update() calls
throughout the source tree (no pmaps currently defer operations, but
we are adding the infrastructure to allow them to do so).

scw 8ace7abc75 A small splx()/spl0()/soft interrupt related optimisation. If we're
