chs | split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.

bouyer | branches: 1.12.22; 1.12.30; 1.12.32;
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.

| 1.11 |
| 09-Dec-1998 |
thorpej | branches: 1.11.10; 1.11.22;
Update for changed scsipi_xfer struct.
|
| 1.10 |
| 19-Nov-1998 |
thorpej | Adapt to the new scsipi_adapter interface.
|
| 1.9 |
| 15-Aug-1998 |
mycroft | Assign my copyrights to TNF.
|
| 1.8 |
| 17-Feb-1998 |
thorpej | - 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.
|
| 1.7 |
| 04-Nov-1997 |
thorpej | 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.
|
| 1.6 |
| 27-Aug-1997 |
bouyer | branches: 1.6.4;
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.
|
| 1.5 |
| 06-Jun-1997 |
thorpej | branches: 1.5.2; 1.5.4;
Pull thorpej-bus-dma branch into mainline.
|
| 1.4 |
| 29-Mar-1997 |
mycroft | branches: 1.4.2;
Use a temporary data structure for holding probe information, rather than a
full softc.
|
| 1.3 |
| 21-Oct-1996 |
thorpej | 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.
