ross e3f2f91bfb Split pci and eisa/isa attachment calls, plus misc cleanup. 2001-05-03 20:34:54 +00:00
bouyer 937a7a3ed9 Pull up the thorpej_scsipi branch to main branch.
This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
  ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
  to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
  peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
  recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
  scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
  (no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
  set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
  the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
  will be requeued, or a REQUEST SENSE will be sent as appropriate.

sommerfeld 851de295eb Change pci_intr_map to get interrupt source information from a "struct
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

Tested on alpha and i386; welcome to 1.5Q

thorpej ea3a1d9c44 Nuke __BROKEN_INDIRECT_CONFIG. 1998-06-08 06:55:54 +00:00
bouyer 6f3bab1f59 Merge scsipi branch in the mainline. This add support for ATAPI devices
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.

cgd 36949596f0 rename pci_map_register to pci_mapreg_map. The latter name is more
descriptive, and allows for a sane name for a function which just digs
the info out of the mapping register but doesn't do the mapping.

cgd 4c654c0acf fixes from Matt Jacob so that these can compile and run on the Alpha.
(aic7xxx has been tested and works on the Alpha, bha has not yet been
tested on thne Alpha.)

jonathan 788394a2e4 Change bha_pci product names to match latest pcidevs:
PCI_PRODUCT_BUSLOGIC_OLD946C -> PCI_PRODUCT_BUSLOGIC_MULTIMASTER_NC
    PCI_PRODUCT_BUSLOGIC_946C -> PCI_PRODUCT_BUSLOGIC_MULTIMASTER

jonathan 79b026a8f3 * Add command struct and modifier definitions for controlling the
ISA-compatible port space of PCI buslogic cards.

* Add call to bha_pci.c to disable the ISA-compatible ports of a PCI
  device.  The ISA-compatible ports are enabled by default, which
  causes the card to be autoconfigured a second time as an ISA device,
  which appears to deadlock the card.

* Change bha_cmd() to return the number of bytes it actually received
  in response to a command, or -1 on error.

*  Use heuristics (checking for bha-only registers, and checking the size
   of the response to BHA_INQURE_EXTENDED) to bha_find, to make sure the
   bha driver never matches an aha (Adaptec    1542 or compatible) device.

A single kernel should now boot on either Adaptec or BusLogic controllers,
provided we always probe for BusLogic devices before Adaptec devices,
but this has not yet been verified.

thorpej 546c8abcee 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.
