mycroft d486b755ca Fix prototype of bha_ccb_phsy_kv() so this compiled on the Mac again. 1999-10-09 22:46:20 +00:00
thorpej a3ef0b7a6d Fix compilation of ISA bha front-end. PR #8528, Takahiro Kambe. 1999-10-01 18:17:12 +00:00
thorpej 415b44a62a Rework the Buslogic SCSI driver in preparation for some pending improvements
to the SCSIPI subsystem.
- Determine more characteristics about the board, including the number
  of concurrent commands that the processor can execute at a time.
- Rework memory allocation strategy so that we can do dynamic pre-allocation
  of resources according to workload.

Thanks to the Linux Buslogic driver for having some useful comments.

thorpej 5f0577babc Adapt to the new scsipi_adapter interface. 1998-11-19 21:43:00 +00:00
thorpej 29d472f53d Garbage-collect the open_target_lu and close_target_lu entry points from
struct scsipi_adapter; they were not used.

Add a scsipi_ioctl entry point to struct scsipi_adapter.  This will be
used to issue ioctl commands to the host adapters.

Inspired by PR #6090, from Matt Jacob.

mjacob 1acc8b53b5 Cute buglet: you can end up with zero CCBs if there were no targets
seen by the adapter. Always leave a minimum so the adapter can
finish attaching- it may be there w/o targets for a reason.

thorpej e08a44b196 - Perform all necessary bus_dmamap_sync() operations.
- Greatly simplify allocation and DMA mapping of the mailbox and ccbs.
- Be more robust against resource shortage errors, and report errors better.
1998-02-06 23:06:44 +00:00
thorpej 8abe76d2f0 Add offset and length parameters to bus_dmamap_sync(), used for specifiying
partial syncs of a DMA mapping.

thorpej a7c5c1ef3c Add dm_mapsize to bus_dmamap_t and rename BUS_DMAMEM_NOSYNC to
BUS_DMA_COHERENT.

thorpej 03a0c2d900 Implement a simple queueing mechanism that makes these drivers much
more robust in resource shortage situations, basically identical to
code I added to the "ahc" driver some time ago.

Thanks to Brad Spencer for the testing help.

thorpej 711fc71012 When creating ccbs, be a little more informative about why we couldn't
shoud creation/initialization of a ccb fail.  Also, don't panic in
these situations.  Instead, simply return an error condition and allow
the caller to deal with it.  It may be the case that we were able to
create one ccb what we can grab, and continue to hobble along.
1997-10-28 23:06:21 +00:00
thorpej d1bfbc66c6 Syncronize with changes to aha.c:
Adjust the number of ccbs allocated during initialization.
Every ccb could potentially lock 64k of memory for dma buffers if bounce
buffers are used.  Instead of BHA_CCB_MAX ccbs using 2MByte, only
sc_link.openings ccbs per device are allocated.  Thus we now use only
256KByte per device present.
(hannken)

Fix a couple of errors in bha_create_ccbs():
- Don't ever let the number of CCBs be creater than BHA_CCB_MAX.
- Fix a fencepost that caused the last CCB allocated to never be put
  on the freelist.

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.

thorpej c0c810cbe0 Initialize the scsi_link before calling bha_init(), since that is how
we check for "wide controller" now.

mycroft 080350dc0d Use a temporary data structure for holding probe information, rather than a
full softc.

cgd 4c654c0acf fixes from Matt Jacob so that these can compile and run on the Alpha.

tested on thne Alpha.)

thorpej fca7fce17e Deal with targets > 7 on wide Buslogic controllers. Remember the "wide"
bit from the extended setup inquiry and key off it to:
- Force synchronous negotiation on targs > 7.
- Read additional information returned by wide cards on inquire setup.
- Read sync period on targs > 7.
- Display sync period/offset on targs > 7.
- Set scsi_link.max_target to 15.

thorpej a4f9e46a87 The MODIFY_IOPORT command does not generate an HACC (command complete)
signal; don't wait for it.

Add a "clarification" cast to the last argument to bha_cmd() in
bha_disable_isacompat().
1996-11-28 00:43:26 +00:00
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 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.
