cgd a7f7004e33 include an MD header if arm32. (No header yet, but there will be 
one eventually.)

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.

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

thorpej 11e78a6b0d Pull thorpej-bus-dma branch into mainline. 1997-06-06 23:43:45 +00:00
cgd 197d80c63a update these so they compile whether or not __BROKEN_INDIRECT_CONFIG 
is defined.

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.

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.

cgd a391172983 include a machine-specific header from ARCH/isa/isa_machdep.h, to define 
the isa_chipset_tag_t type, and to define or prototype:
	isa_attach_hook()
	isa_intr_establish()
	isa_intr_disestablish()
i.e. the machine-dependent functions to be used my MI ISA code.
Remove prototypes for the latter two functions from this file.

cgd 2b96f0705b delete unused cruft (the 'software conventions' chunk). 1996-03-16 02:00:43 +00:00
cgd 5087096150 pass a bus_chipset_tag_t (defined in <machine/bus.h>) to the bus when 
attaching, and to the devices when attaching them.  #include <machine/bus.h>
to make this backward compatible with old #include requirements.
Also, clean up idempotency so that isa/eisa/pci "var.h" headers are
consistent (make them all idempotent).
 1996-03-08 20:25:22 +00:00
cgd 3ca5707161 make ISA bus match/attach, and sub-device configuration machine-independent. 1996-02-28 01:43:45 +00:00
mycroft 3da4b2a160 The IST_* and IPL_* constants are not bus-specific; don't treat them as such. 
Change splimp -> splnet in Ethernet, ARCnet, and FDDI drivers.

cgd 5a29222f9c prototype isascan, spacing 1995-06-07 06:45:44 +00:00
cgd 8a640328ed clean up several ISA device interfaces: autoconfiguration, header 
inclusion, and interrupt configuration.  more work still needs to be done,
but it's getting better...

mycroft 3f5e4f423f Implement dynamic IRQ configuration and IRQ sharing. Inline spl*() calls. 
Reorganize and clean up the relevant code.

mycroft 23c5083a45 Minor changes. 1994-03-30 18:35:11 +00:00
mycroft 5eb99ad76e New autoconfig mechanism. Hacked at the moment to use old config(8), but 
look mostly like config.new to drivers.
