leo d30382ffb4 Don't call isa_dmainit() when NISADMA == 0. 1998-06-11 08:29:33 +00:00
thorpej ff76b8e96b Change the ISA DMA API to take an isa_chipset_tag_t rather than
a struct device * corresponding to the ISA bus device.  The ISA DMA
controller driver functions have been renamed and now take a struct
isa_dma_state *, and are called indirectly by machine-dependent code
which provides the DMA state.

These changes allow e.g. `ofisa' (the OpenFirmware configuration
mechanism for the ISA bus, used by e.g. Sharks) to use the MI ISA
DMA controller code.

drochner da5b8105bd Remove BROKEN_INDIRECT_CONFIG relicts. 1998-05-05 21:41:18 +00:00
thorpej 8c1b46c2f5 Remove the `delay port' stuff since nothing uses it anymore (can't reliably
use it on modern chipsets).

augustss a50d4ba893 XXX Add a drq2 locator for the ISA bus. Many sound cards need
two DMA channels to do e.g. full-duplex.  This allows
a way of specifying the second channel in a sane way.
THIS IS TEMPORARY.  The drq2 locator will go away when
the locator system has been changed to allow multiple
values per locator.
1997-08-26 19:26:38 +00:00
jtk 26414c7820 use locator defines in "locators.h" to index cf_loc[]
still to be done and/or decided not to be done: replace all *UNK uses in
isa code with the native names from locators.h

cgd 3573080902 split isasearch (!__BROKEN_INDIRECT_CONFIG) completely off of
isascan (__BROKEN_INDIRECT_CONFIG), and attempt multiple match/attach
of cloning devices in isasearch().  (If a match/attach succeeds for
a cloning device, try it again.)
1997-01-26 03:49:28 +00:00
cgd 74187419b6 The last change fixed a last-minute goof in the __BROKEN_INDIRECT_CONFIG
case, but added a typo (extra parenthesis) in the !__BROKEN_INDIRECT_CONFIG
case.  fix it.
1996-12-08 00:14:03 +00:00
cgd 243ef518d2 fix a (fatal) bug in the __BROKEN_INDIRECT_CONFIG changes checked
in yesterday.  (got a little bit careless with #ifdef'd variables.)
1996-12-05 22:16:04 +00:00
cgd 197d80c63a update these so they compile whether or not __BROKEN_INDIRECT_CONFIG
is defined.
1996-12-05 01:25:23 +00:00
cgd 452ba6e098 restrict the FSTATE_STAR prohibition (and panic) to the i386 only. Cloning
devices actually do make sense on indirect-config busses, because you
might be able to have more than one of the busses!  In addition, they're
useful because they don't require unit numbers to be wired down, so you
could e.g. have vga* at indirect? and vga* at direct?, and have the first
one found be unit number zero.  Finally, devices which can divine their
own ports numbers, etc., actually should be cloning, even if you know you'll
only have one bus that they can live on.

thorpej 769a499800 New bus.h implementation/interface:
- No more distinction between i/o-mapped and memory-mapped
	  devices.  It's all "bus space" now, and space tags
	  differentiate the space with finer grain than the
	  bus chipset tag.
	- Add memory barrier methods.
	- Implement space alloc/free methods.
	- Implement region read/write methods (like memcpy to/from
	  bus space).
This interface provides a better abstraction for dealing with
machine-independent chipset drivers.

christos 58953408cb printf -> kprintf, sprintf -> ksprintf 1996-10-10 22:04:48 +00:00
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).

thorpej 52e2ab70b0 #include <machine/intr.h> to get IST_* definitions. 1996-05-14 00:31:04 +00:00
mycroft cec36bf8d5 Use intr.h. 1996-05-12 23:51:23 +00:00
thorpej e32158478e Correct a couple of comments ... port 0x84 produces a 1.25us delay when
read, not 2.5us.  (I must have been confused; thanks Charles, for
correcting me.)
1996-05-08 23:32:31 +00:00
thorpej 6fb58044fd Map port 0x84 (which is used to generate a 2.6us delay) in isaattach().
Since this port is needed by at least a few drivers, export its i/o handle
via isa_attach_args.

christos e8a8a6298c - prototype fixes 1996-04-29 20:02:32 +00:00
cgd e6456e7285 on non-i386 systems, include <machine/intr.h> (per charles's proposal on
tech-kern (?)), to get the IPL_* and IST_* types.  pass the machine-dependent
cookie given at attach time on to sub-devices, so they can use it to access
the interrupt functions properly.

thorpej 6d9ea4cf59 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.

children.
