thorpej 3249813e11 For whatever reason, the firmware seems to enable PCI loopback mode if it
also enables BWX.  Make sure it's enabled if we have an old, buggy firmware
rev.

thorpej d4d49905dd Add support for using BWX for PCI config space and PCI i/o and mem space
on the ALCOR2 and Pyxis.  BWX is enabled iff:
- It hasn't been disabled by the user (patch `cia_use_bwx' or build cia.o
  with the option "CIA_USE_BWX=0"),
- it's enabled in CIA_CSR_CNFG,
- we are running on an EV5-family processor,
- BWX is in the processor's capabilities mask.

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.

thorpej d19fbe1196 Garbage-collect the old confargs stuff that was used in the Early Days.
It isn't really appropriate anymore.  Replace it with a real mainbus
attach args structure.

thorpej 6172f5a0ac Use flags instead of a bunch of booleans. Add a "use bwx" flag. 1998-05-12 19:07:21 +00:00
thorpej 34bbe5cd80 Rework ALCOR/ALCOR2/Pyxis recognition Yet Again. (Actually, just the
way it's displayed, and mask off the revision once we've determined
which chip we're talking to.)

thorpej 4ccb48a525 Try (again) to get the chip number right for Alcor and Pyxis, using the
following (iffy) hueristic:

	CIA revision 1   -> 21171
	CIA revision 2   -> 21172
	CIA revision > 2 -> 21174
1998-04-28 18:11:35 +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.

thorpej 399f3639cf Don't assume that we'll be using direct-mapped DMA for PCI. 1998-01-17 03:39:51 +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.

thorpej cb32cf1ece Pull in DEC_EB164 and DEC_KN20AA options. 1997-09-02 13:24:48 +00:00
thorpej 693b3e7262 Nuke the idea of <machine/options.h>. It completely defeats the purpose
of fine-grain option dependencies.

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.

thorpej 46b89d7739 Pull thorpej-bus-dma branch into mainline. 1997-06-06 23:54:24 +00:00
cgd cc93b2c4eb pass memory- and i/o-enabled flags down via the PCI bus and device attach
arguments, so that a device can tell if its memory and I/O spaces are
enabled.  The flags are cleared, depending on the contents of devices CSR
registers, in the machine-independent PCI bus code.

cgd 90789b53dd by default, provide RCS IDs for NetBSD/alpha kernel files in kernel binaries.
This can be disabled (to save a bit of space) with the NO_KERNEL_RCSIDS
options, which is present but commented out in the ALPHA config file.
In ELF-format kernels, these strings are present in the kernel binary but
are not loaded into memory.  (In ECOFF-format kernels, there's no easy way
to keep them from being loaded, so they _are_ loaded into memory.)

cgd a60b90caa9 clean up NetBSD RCS ID strings, include machine/options.h 1997-04-07 02:01:16 +00:00

cgd e9abc8540f remove all traces of __BROKEN_INDIRECT_CONFIG (except in shared drivers) 1996-12-08 00:22:08 +00:00
cgd 8b6a32d1c1 update these so they compile whether or not __BROKEN_INDIRECT_CONFIG
is defined.
1996-12-05 01:39:27 +00:00
cgd 77baf28d70 update for new extent management code. Most importantly, we can't call
the chipset space init functions multiple times, since that would clobber
extent allocations made between the two calls.
1996-11-25 03:55:46 +00:00
cgd 8ffccdfae0 preliminary support for the EB164. The EB164 is more or less a 'normal'
21164 + 21172 box, with Yet Another Way of doing interrupts.  The
interrupt mapping and handling code hasn't been written yet, and none
of this code has been tested.  (Checkpoint of work in progress.)
1996-11-11 21:08:10 +00:00
cgd 1b03f1bca7 update for new bus.h macros. bus_io_* and bus_mem_* integrated into
single bus_space_* framework.  Unfortunately, bus_space_{read,write}_*
operations still imply barriers.  That will change soon.

cgd 2a73ef60b7 change cfprint_t type definition to take a const char *, rather than
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).

cgd 7a83b5d468 some cleanup for -Wall 1996-07-11 03:30:11 +00:00

thorpej 08607bc611 New device attachment scheme:
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.
1996-03-17 01:03:02 +00:00
cgd deb4082f80 wholesale update from my NetBSD/Alpha source tree. Includes:
Support for AXPpci CPUs,
	Support for AlphaStation 600 CPUs,
	new boot block structure, which requires an 'installboot'
	    program and works a lot like the NetBSD/sparc boot blocks.
