Thanks to Hal Murray for reporting the problem and testing the fix.

bouyer 0e7cd755f4 use the correct variable in a debug printf(). 2000-06-05 21:47:25 +00:00
bouyer b063b2ec36 Separate the sheduler from the main script, allocate another DMA-safe
memory page for the sheduler. Put the main script in the on-chip RAM when
available.
Avoid a null-pointer dereference when DSA is invalid.

bouyer 863014523a - split siop.c in script-dependant vs script-independant part, for
comming esiop
- add a reset callback for bus-dependant registers settings

bouyer 904ca34539 Ops, restore sync/wide parameters after a reselect.
Also, better handling of parity errors.

bouyer 4c9516aa3b Rework the command queue, to avoid having commands blocked at the end
of the queue. Load is now properly balanced across all disks of the same bus.

bouyer 2306b4a34e When a WDTR message is rejected, initiate sync negotiation anyway.
When a SDTR message is rejected indicate that target is async
Add a missing bus_dma_sync call.

bouyer f5b572d26b - LP64 issues in debug printfs.
- on a phase mismatch, do byte recovery only if we were in data phase.
  Otherwise just clear the fifo.
- Properly handle reject of a sync or wide negotiation.

bouyer 3bb9a5f666 - do sync/wide negotiation
- use a circular queue for the start slots, so that order has better chances
  to be preserved.

bouyer eba93ce7d2 Ops, need to restore correct DSA value after a phase mismatch, we may have
been interrupted during a S/G operation.

bouyer 88be4752d0 - Change the script to start new commands in an asyncronous way, using
'command slots' in which the host can put command and wait for the script
 to start them
- Change siop.c to do full disconnect/reslelect, allowing as much as one
 command per target/lun to run in parallel.
- Fix bug in registers init where a board without BIOS would end at
  ID 0 (now the driver works on alpha too).
- better handling of messages, sending back a MSG_EXT_SDTR in response to an
  incoming MSG_EXT_SDTR, and MSG_MESSAGE_REJECT for unhandled messages.
- fix use of bus_dmamap_sync() and htole32().
- supports shared interrups
- change some int8 and int16 to int, for alpha and mips benefits ( suggested by
  Toru Nishimura)

bouyer 19ada4a82a Snapshot of work in progress: new driver for the NCR 53c8xx SCSI controller
(the name 'siop' is still being discussed, may change).
Only basic disconnect/reselect for now, no sync/wide negotiation.
Tested with 810A, 875 and 895 on i386 only.
The bus-independant part should also be able to handle the 53c720 and 53c770.
A new driver with enhanced script should appear for the 825/875/895 'soon'.
