thorpej 6dc28f5445 CIA and Pyxis have 8 scatter/gather TLB entries. 1998-06-04 01:18:22 +00:00
thorpej 32fef69ef7 Define the CIA control register. 1998-06-04 01:04:11 +00:00
thorpej d94f02f9fd Ok, now we _REALLY_ have Pyxis recognition correct. There are two systypes
that can have Pyxis: EB164 (AlphaPC164LX and AlphaPC164SX) and DEC_550 (Miata),
and these systypes/variations _always_ have Pyxis.

I made yesterday.

thorpej d6041754c2 Allow the DMA tag to specify a boundary contraint. If the device has a
more strict boundary, the map will use it, otherwise the map will inherit
the tag's, unless the tag's constraint is 0 (no boundary constraint).

frueauf 554cce1e94 Remove double "options GATEWAY" entry. 1998-06-03 10:03:25 +00:00
thorpej 28486ff301 Remove the _cookie member of the DMA tag; it's not used by anything. (This
was already done to the i386 port.)
1998-06-03 06:47:41 +00:00
thorpej 7b37a276e2 Sync w/ i386 port:
Optimize the ISA DMA map load somewhat; don't traverse the buffer twice.
Instead, just attempt to do a normal load first.  If we exceed the bounce
threshold or the number of segments, then we bounce the transfer.
1998-06-03 06:43:04 +00:00
thorpej 6ffa35b390 Sync w/ i386 port:
When loading a DMA map, if the page's physical address exceeds the bounce

bounce the transfer).
1998-06-03 06:41:51 +00:00

thorpej 0b25bb43b3 Adjust bus_dmamap_sync() for the R4000; in that case, use the stashed
virtual address for the segment, rather than the physical address, and
adjust the cache call appropriately.

scottr da2f2cb79f Store the PA of the framebuffer in the softc. This eliminates the need
for the sc_phys callback; we can just store the PA in the grfbus attach
args, rather than a function pointer, which simplifies the code nicely.

drochner dc8a7077ed Handle the i386/PMAP_NEW copyout() differently:
Don't try to avoid faults when the PTEs are checked. Set pcb_onfault
instead so that trapwrite() is called as if the PTE were RO.
This is faster than explicitely ckecking the PDEs - at least in the
majority of calls where the PT is already present.

thorpej 1ef3ca572e - Additional rearrangement for the sake of running on the DECstation some
day.
- Convert to use bus_dma.
- Fix cleaning up unaligned start address.
- Correctly determine if the device supports Fast SCSI, and adjust the
  minimum sync period accordingly.
- Compute minimum sync period correctly on the 25MHz devices.
- Use GPI2 to determine if we're a 25MHz or 40MHz device.
- Currectly determine SCSI ID and "fast mode enabled" for the built-in
  TCDS on DEC 3000 models, using cached information from the PROM environment.

thorpej 3aa84f9e26 - Make this into a proper attachment (i.e. use asc_tcds) and clean up

- Set FCLK in the CFG3 register if we have a > 25MHz clock.
- Indicate that we support Fast mode to the back-end if we're told we're

thorpej 4631dca956 Rewrite at least the R{2,3}000 case for bus_dmamap_sync(), in hopes of

1998-05-24 23:45:29 +00:00
thorpej d3ead78027 Several changes to the TurboChannel Dual SCSI driver:
- Fix the autoconfiguration model; the TCDS children don't attach to
  TurboChannel, so don't make it look like they do.
- Make the driver use bus_space (not bus_dma yet; soon)
- Recognize the PMAZ-FS (baseboard fast SCSI on DEC 3000s) and the
  PMAZB-AA (TCDS option card) and PMAZC-AA (TCDS fast SCSI option card).
- Rearrange it a bit, so that it can eventually be made into an "MI"
  TurboChannel driver (i.e. work on DECstations).

cgd a2c213c028 fix code so that a 'generic' OFW kernel (which only uses OFW drivers)
will again compile.  This code needs a bunch of cleanup, and the
"generic OFW kernel" code should probably be split into a different
directory than the code which implements the interface to OFW.

drochner 6de27a7083 Make copyout() and Co. work with PMAP_NEW on real i386 processors.
PMAP_NEW doesn't fault in page table pages automatically on access to
PTmap[], so we have to check the PTD explicitely.
If a PTP is needed, call uvm_fault(). pmap_enter() will DTRT.
Move calculation of the index into PTmap[] inside the loop in copyoutstr()
(non-PMAP_NEW case). Page boundary crosses are rare, so this should save
some cycles in average.

the Cypress PCI-ISA bridge, which has IDE wired to compat mode on functions
1 and 2; the 164SX does _not_ have PCI IDE on device 11 like other AlphaPCs).
