cgd cffb580806 Implement the more flexiable `evcnt' interface as discussed (briefly) on
tech-kern and now documented in evcnt(9).

leo 7c72f9361b Change comment about isa_intr_establish() as discussed on tech-kern. 1998-11-30 12:57:10 +00:00
jonathan ea4898c76c Add arc as a target platform. 1998-09-11 19:39:28 +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.

thorpej 8c1b46c2f5 Remove the `delay port' stuff since nothing uses it anymore (can't reliably
use it on modern chipsets).
1998-04-15 01:44:23 +00:00
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.
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 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.
1996-05-05 01:14:07 +00:00
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).

mycroft 3da4b2a160 The IST_* and IPL_* constants are not bus-specific; don't treat them as such.

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...
