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.

thorpej 53d3aa940b Sync with recent change made to bha.c by mjacob:
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 eda74e6121 - 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.

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 6e8facbdcc When creating ccbs, be a little more informative about why we couldn't
should 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.

thorpej 1bfea0bd23 Fix a couple of errors in aha_create_ccbs():
- Don't ever let the number of CCBs be creater than AHA_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.

hannken 5d4f988920 Adjust the number of ccbs allocated during initialization.
Every ccb locks 64k of memory for dma buffers.
Instead of AHA_CCB_MAX ccbs using 1MByte only sc_link.openings ccbs
per device are allocated. Thus we now use only 128KByte per device present.

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

is 07b064e02e New ARP system, supports IPv4 over any hardware link.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.
