now takes a device_t to be the parent of the bus that is being created.
Most SIMs have been updated with a reasonable argument, but a few exceptions
just pass NULL for now. This argument isn't used yet and the newbus
integration likely won't be ready until after 7.0-RELEASE.
the newly added DEV_EISA. This is done so that these back-ends can
be compiled on platforms not providing in{b,w,l}()/out{b,w,l}() and
friends (but may wish to use them together with bus front-ends other
than the EISA one).
Free approx 86 major numbers with a mostly automatically generated patch.
A number of strategic drivers have been left behind by caution, and a few
because they still (ab)use their major number.
- Sanitize dpt_alloc().
- Add helper functions for resource alloc/release.
- Add detach method.
- Relocate definition of devclass_t.
- Move some debugging output behind bootverbose.
- Implement an identify method for ISA devices
but don't use it right now.
- Add support for ISA based DPT adapters (this doesn't quite work yet).
- Sync dpt_eisa.c with my local copy.
- Simplify how EISA IDs are matched.
- Prototype.
- Formatting nits.
- Conform to how I do things in dpt_pci.c/dpt_isa.c.
- Modify dpt_scsi.c:dpt_alloc() to DTRT with newbus.
- Add some comments to dpt_scsi.c:dpt_pio_get_conf().
- Add additional check to dpt_scsi.c:dpt_get_conf().
- Add some useful error messages to dpt_scsi.c:dpt_init().
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot). This is consistant with the other
BSD's who made this change quite some time ago. More commits to come.
configuration information from a DPT card at a given port.
This is needed by the ISA bus front end (still to come) and the EISA
bus front end (which hasn't ever worked).
- Blow away dpt_eisa.h as the information it contains does not justify
an additional file.
- Convert dpt_eisa.c to use the onboard config instead of trying to
read the EISA configuration registers.
Diskslice/label code not yet handled.
Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)
Add the correct hook for devfs to kern_conf.c
The net result of this excercise is that a lot less files depends on DEVFS,
and devtoname() gets more sensible output in many cases.
A few drivers had minor additional cleanups performed relating to cdevsw
registration.
A few drivers don't register a cdevsw{} anymore, but only use make_dev().
Bump the lun field in the eata ccb to 5 bits. We still only
use 3 of them, but we may use the rest at a later date.
dpt_scsi.c:
Default to only 32 S/G segments.
Bzero our CCB array after allocation.
those extra ones yet, anyway.
In dpttimeout, expect that the controller will complete aborted CCBs through
the interrupt handler. This corrects a panic that was caused by completing
the same transaction twice during timeout recovery.
Honor the tag times types expressed by the user and pass them down to
the controller.
