mjl 4622761326 Enable workaround for isapnp assigning already used interrupts to pnp
cards by masking them out with a "options ISAPNP_ALLOC_INTR_MASK=..."
in kernel config.

mycroft 77274e73c6 Add a `variant number' to the tables, so we can handle slight variations in
the chipset without doing something substantially more gross.

mycroft fd400e0ddc Add a kluge to ignore I/O and memory ranges with a size of zero, so we don't
blow up in bus_space_{map,unmap}().  At least one card uses this to `disable'
a logical device.
(XXX There's probably a better way to do this.)

augustss ddb8209b40 XXX Add a disgusting hack to make the CS sound chips work in PnP mode.
XXX Read about it in isapnp.c.

fvdl c312dc3f08 Avoid looping forever with cards that can only use one I/O address,
and specify a 0 alignment.

hannken f568c6347c Fix last commit -- NISADMA is either 0 or 1. 1998-10-10 13:43:10 +00:00
thorpej 5599443810 If ISA DMA is not present in the kernel (i.e. no ISA DMA-using devices
configured in), don't call ISA DMA functions to check for DRQs being
free.  Just return EINVAL in this case.  Fixes PR #6187, from Herb Peyerl.

christos c1303944f7 Add a hook that resets the bios configuration from the pnp devices
thus making them invisible to isa probes [from OpenBSD]

christos bdb2269a46 Create a master list of pnp logical and compatibility device codes instead
of hard-coding it into each driver and use a centralized probe function.

thorpej 6ea0ab26e2 Don't reference functions defined in isadma.c if we don't have to,
since we might not have any ISA DMA-using devices configured, thus
isadma.c won't be compiled.  Fixes a problem reported by Kevin Lahey.

Also, since there are only 8 DMA channels, don't bother checking
DRQs 8 - 15.

christos c12bf4cc9f DTRT with level and edge interrupts:
- add a type field to the isapnp_pin struct and set to IST_EDGE or
      IST_LEVEL depending on the card configuration data.
    - use the irq type field in all the drivers instead of hardcoding it.

thorpej e0ccf46ed0 In isapnp_alloc_irq(), use isa_intr_alloc(), since it performs resource
conflict checking.

thorpej 16905ceeda Make sure we don't allocate a conflicting DRQ. From Christos. 1997-10-27 22:16:49 +00:00
mikel 32407c5e4f don't forget to unmap read port in match routine, if successful; also
ensure sc_ncards is initialized
short-circuit probing for cards once first is found in match routine

christos 041fb607e0 Add a break; in the irq/drq allocation loop so we take the first one instead
of the last one.

christos 2fe3b9727a - increase string space for device class names
- fix the parser so that non-compliant isapnp devices work, and we
  give up when there are too many errors (some on-board pnp sound/atapi/game
  soundblaster compatible card).  reported by chuck cranor
- fix the parser so that configuration tags that come after the
  end-dependencies tag or before the begin-dependencies tag are merged
  in properly (gravis ultrasound). reported by gary duzan
  We now build a tree of card -> logical-dev -> conf, and in the end we
  convert it to a list of conf...
