thorpej 58509e699f Add support for UVM. 1998-02-24 07:38:01 +00:00
thorpej 314f40f8d8 We can't count on the CIA revision register telling us if we're a 21171
or 21172, so make the chip/revsion output a little more sane.
1998-02-12 20:43:45 +00:00
thorpej 612aea038c Use the common _bus_dmamap_sync() as the _dmamap_sync method in the
bus_dma_tag_t.

ross 6270ed1711 Add the A12 fast ethernet controller, an if_de.c hacked (prior to
bus_dma's appearance in the tree) to support sram bounce buffers.
When a busified if_de.c appears, this module can join awd.c at the
end of that long walk on a short pier.

ross 12f93343cd Add basic platform support for NetBSD on the Avalon A12. I'm running this
CVS commit on one right now...

thorpej 8df306036a Initialize s/g DMA registers in the same order as the CIA chipset's:
(1) window base
	(2) window mask
	(3) translation base
1998-01-17 22:46:55 +00:00
thorpej 3366b987d0 Put SGMAP-related stuff in the DMA map structure directly, rather than
indirecting through a pointer.
1998-01-17 21:53:52 +00:00
thorpej 63db8935a6 Fix initialization of DMA window 0:
- Make sure the page table is aligned to at least 32k.
- Don't consider the MEMCS signal when checking for a window hit.
1998-01-17 03:43:59 +00:00
thorpej 9554b5a243 Update for "minptalign" argument to alpha_sgmap_init(). 1998-01-17 03:40:32 +00:00
thorpej 399f3639cf Don't assume that we'll be using direct-mapped DMA for PCI. 1998-01-17 03:39:51 +00:00
thorpej 5419debcb7 Adjust for config changes. 1998-01-12 10:21:02 +00:00
thorpej 023044a749 Clean up printing of chipset revision/capabilities. 1997-10-27 01:08:42 +00:00
thorpej 611012d836 Make the copy_region methods do overlapping copies properly. Fixes
port-alpha/4216 (Chris Demetriou).

cjs c44bfc9eae Make compile without DIAGNOSTIC set. 1997-10-14 06:22:02 +00:00
thorpej 0c2efd7025 Add a "scrollskip" member to wscons_emulfuncs (XXX even though it's not
a function) which specifies how many lines will be skipped when scrolling
up when the bottom of the screen is reached.  Dumb framebuffers skip 10
lines (as before) because the copies are s ... l ... o ... w, but it's
silly to skip 10 lines on VGA, since the copies are much faster, so we
only skip one in that case.

thorpej 15e10104d5 Define the BWX-capable regions of the CIA chipset's address space (mem,
i/o, pci config space mode 0, pci config space mode 1) and the CIA
REV and CNFG CSRs.
1997-09-17 01:35:34 +00:00
thorpej 879c4c5cf4 If the CIA revision is >= 2, read the CIA configuration register, and
remember its contents.  Print out a bit of information about the chip,
including whether or not it supports the EV56 BWX instructions.
1997-09-17 01:34:18 +00:00
thorpej 37b8edbeac In addition to MAS_ABT, check TAR_ABT when doing configuration space
reads.  This is necessary because of newer AlphaStation firmware doing
the Wrong Thing with target aborts behind PCI-PCI bridges, much like they
do the Wrong Thing with master aborts.  Reported by Matthias Drochner.
1997-09-15 23:31:15 +00:00
thorpej 12f6c5aba1 Make sure to clear MAS_ABT if we received one. 1997-09-15 23:01:29 +00:00
thorpej 3c3c6a3b31 Use the symbolic name for "received master abort". 1997-09-15 22:35:54 +00:00
thorpej 8ff22715e8 Define bits in the CIA_ERR register. 1997-09-15 22:34:38 +00:00
thorpej f784e8dc15 Apparently, new AlphaStation 500/600 firmware has the same problem with
PCI master aborts as eb164 firmware, so use the same workaround mechanism
on all system types (clear error register's master abort bit, and check
it after accessing configuration space), not just eb164's.

This also fixes a bug on eb164's - when making the Alpha port compile
again, I made an error that caused this to not be used on eb164 systems,
either.  Thanks to Matt Jacob for pointing out this goof.

thorpej ed2ec4869c Update for Chris Demetriou's changes made to the bus.h interface:
- bus_space_copy -> bus_space_copy_region (for consistency)
- "cacheable" argument becomes a "flags" argument instead, with
  BUS_SPACE_MAP_CACHEABLE and BUS_SPACE_MAP_LINEAR flags currently
  defined.

thorpej 80e3db443f Apply a change made to other PCI chipsets:
don't expect/provide pci_decompose_tag to be a MI, public function.  It
wasn't intended to be to begin with, and uses of it (e.g. the one in the
'de' driver) are quite likely to be incorrect.

thorpej 693b3e7262 Nuke the idea of <machine/options.h>. It completely defeats the purpose
of fine-grain option dependencies.

thorpej e234ed15b6 Fix oversight in a previous commit. 1997-09-02 12:54:27 +00:00
thorpej 375ad27ed8 - Garbage-collect all DMA-related initialization, calling a separate
*_dma_init() function instead.
- Pass the appropriate bus dma tag to children.

thorpej aa7a2876e6 Treat bus space tags more like pci chipset tags and bus dma tags: allocate
them statically within a chipset's state structure, and pass them to
the *_bus_{io,mem}_init() functions.

mjacob 23d0cae1eb It helps streaming performance substantially to enable bursts and more up hose
packets. It's not clear whether latency will be affected much. It could be.
However, for the time being, getting full rates out of HIPPI or SCSI are what
interests us at NASA, so we'll hew to this bias.
