- Trivial streamlining of logic in dpt_poll().

ad 4763c00196 - Don't use our own private endian conversion cruft (from OpenBSD). 
- SmartRAID V is not and will never be an EATA board (from OpenBSD).
- Use dpt_outl() when issuing EATA command packet address to HBA.
- Fix a style nit.
- Fix a typo.

ad fd992c5320 Prepare a little for the addition of an interface to user-space. 1999-10-23 16:26:32 +00:00
ad b3e97ca54b Nuke some silliness. 1999-10-20 12:27:38 +00:00
ad eccc3630ec DPT_MORE_TIMEOUT was scaled wrong. 1999-10-20 11:54:10 +00:00
ad 675c12dbcb - Don't get stalled by a bogus HA_ST_MORE condition. 
- Don't trust HA_ST_MORE again if the above situation occurs.
- Nuke bitfields in 'struct eata_sp'.
- Don't bother using scatter-gather if DMA map contains only 1 segment.
- Return TRY_AGAIN_LATER and not COMPLETE if an EATA command times out.
- Check SCSI status in dpt_inquire(), not just HBA status.
- Some cosmetic changes and sanity checks.

thorpej da257060f5 Avoid silly namespace collision w/ some Alpha signal-related variables. 1999-10-04 23:57:32 +00:00
ad e8d7fe2144 - Save SCSI status in the request. 
- In dpt_intr(), if no interrupt is signalled but the HBA has indicated
  that more data will be available soon (HA_ST_MORE), save a context switch
  and wait for the data.

thorpej 63b8530b4e Update for SCSPI changes. 1999-09-30 23:04:39 +00:00
ad 19bd684e8a - Remove a couple of items from the TODO list.

ad f6e42db75a - Move initial reset code into dpt_readcfg() 
- Bus specific front-end is now responsible for reading EATA configuration
- EATA configuration data is now saved in the softc
- Make synchronous writes work properly
- Don't ignore HBA timeouts in dpt_cmd()
- Prefix eata_cfg's members with `ec_', not `dc_'

ad 9876b8900e - Fix some comments. 
- Synchronous writes musn't linger in the HBA's cache.
 1999-09-28 23:39:14 +00:00
ad 21a6ff6082 - Wait up to 2 seconds for HBA ready before executing CP_PIO_GETCFG 
- Remove some unneeded memset() calls and assignments
- Fix comment on dpt_done_ccb()

ad 48a0b6237a A driver for DPT EATA SCSI adapters. dpt.c contains a brief TODO list. 1999-09-27 23:41:47 +00:00
