leo c3de71f0bf Fixup icu-code. It now works for both ISA and PCI. 2002-02-23 20:44:45 +00:00
thorpej 3835413bc1 Overhaul of the ISA autoconfiguration code to support direct
configuration of devices logically attached to the ISA bus:

* Change the isa_attach_args to have arrays of io, mem, irq, drq
  resources.
* Add a "pnpnames" and a linked list of "pnpcompatnames" to the
  isa_attach_args.  If either of these members are non-NULL,
  direct configuration of the bus is being performed.  Add an
  ISA_DIRECT_CONFIG() macro to test for this.
* Drivers are not allowed to modify the isa_attach_args unless
  direct configuration is not being performed and the probe fucntion
  is returning success.
* Adapt device drivers -- currently, all driver probe routines return
  "no match" if ISA_DIRECT_CONFIG() evaluates to true.

leo 2bcf7a5971 Add 'prev_sr' argument to milan_isa_intr() so we can properly defer interrupts
that come in at the wrong time.

leo cfc3edb550 remove some debugging leftovers. 2001-05-16 08:45:50 +00:00
leo b38e85279e Allow attachment of a pc-keyboard at console attach time. 2001-05-14 13:18:47 +00:00
leo 164b045485 Split the ISA common attachment stuff and the interrupt handling.
There are too many differences between the Hades and Milan in this area.

leo a5fdf3f1cf Atari specific stuff to implement the Milan floppy. The Milan uses standard
ISA floppy hardware. Configure as:
    fdcisa0 at isa? port 0x3f0 irq 6 drq 2
2001-03-16 21:31:55 +00:00
leo b44e732ff6 Expand bus_dma implementation. It will now handle the bounce buffer
extensions needed to make the isa floppy driver on the Milan work.

mrg ca5133d3fb remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h> 2000-06-29 08:22:17 +00:00
mrg 2f159a1bac remove/move more mach vm header files:
<vm/pglist.h> -> <uvm/uvm_pglist.h>
	<vm/vm_inherit.h> -> <uvm/uvm_inherit.h>
	<vm/vm_kern.h> -> into <uvm/uvm_extern.h>
	<vm/vm_object.h> -> nothing
	<vm/vm_pager.h> -> into <uvm/uvm_pager.h>

also includes a bunch of <vm/vm_page.h> include removals (due to redudancy
with <vm/vm.h>), and a scattering of other similar headers.

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

leo 4911054546 Allow storage-space to be passed to the alloc_bus_space_tag() functions. This
permits static tags to be used during early console init.

leo 761038f279 Correct the test for a free-slot for isa_intr_alloc(). Also issue a warning
that should make it clear in which slot the card is expected to be in.
Isapnp is not what it seems to be on the atari (where interrupts are
hardwired to slot numbers).

leo 6b31bde1bb Implement at least a bit of isa_intr_alloc(). 1999-10-21 15:26:57 +00:00
leo 54f2532106 Change the way that bit's are cleared in the InterruptPending register of
the 68901. Do this now by _assigning_ ~<bit_to_clear> instead of the
previously used 'andb ~<bit_to_clear>'. The latter caused a rwm-cycle that
caused a race condition to happen when an interrupt arrived between the
Read and Modify-Write.
Anyway, this solved my hanging keyboard problem.

leo c754d06437 Return NULL when trying to establish a non-EDGE_TRIGGERED interrupt.
This can be used by drivers to choose another type. Currently used in
isnd4bsd.

in this file.

leo 6c721e05f1 Fix typo. 1998-06-11 08:32:00 +00:00
thorpej 680a3d77f4 Add isa_dma{freeze,thaw}(), used to temporarily stop and then restart
all ISA DMA.  Needed by e.g. the SmartCard reader for Sharks.
1998-06-09 01:04:17 +00:00
thorpej 7c54de8712 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.
