thorpej d561771013 Add missing copyright noticed (it ended up in eisareg.h by mistake). 2000-08-11 00:46:17 +00:00
thorpej e207174eb0 Add functions to read EISA configuration data for MEM, IRQ, DMA, and IO.
XXX Just error stubs on the i386 right now -- someone needs to write
XXX EISA BIOS code for i386.

thorpej 30f7d691a0 Declare the ECU data in an MI location, so that drivers can
use it.

cgd 6ac54498c7 pull eisa_machdep.h in from machine/ 1999-03-19 03:01:50 +00:00
jtk 024b25a651 use locator defines in "locators.h" to index cf_loc[]
still to be done and/or decided not to be done: replace all
EISA_UNKNOWN_SLOT uses in eisa code with the native names from
locators.h

thorpej fbc0df0a1a Pull thorpej-bus-dma branch into mainline. 1997-06-06 23:30:02 +00:00
thorpej 16c4c5af26 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.

cgd 432b9ff657 add support for the alpha 1996-04-12 06:34:36 +00:00
cgd d645bb042d make the EISA code look a bit more like the PCI code, in the way
the bus is configured, interrupts are handled, etc.  machine-dependent
header (machine/eisa/eisa_machdep.h) defines eisa_chipset_tag_t and
eisa_intr_handle_t types, and the following functions:
	eisa_attach_hook()
	eisa_maxslots()
	eisa_intr_map()
	eisa_intr_string()
	eisa_intr_establish()
	eisa_intr_disestablish()
Don't define the interrupt establish/disestablish functions directly
in terms of the ISA functions any more (on some wacked out systems,
there can be a difference).

cgd caf3bddd6f make this a little bit closer to the pcivar.h header; no reason to
be gratuitously different in some places.  (just cosmetic changes.)

cgd 780657a591 don't export eisa_cd. Drivers shouldn't need it, and, indeed, if they
do, they're probably doing thing the Wrong Way.

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.

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).

cgd 4bd7608739 Better EISA autoconfiguration, per PR 1959. 1996-02-27 00:20:54 +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 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...
