set the interrupt handler to be INTR_MPSAFE now that xpt_done() can be
called without Giant. Giant is still on the top half of the driver and
the timeout handlers.
in a TAILQ. Re-arrange some of the ecb elements so that they can stay
stable through alloc/free cycles while the rest get bzero'd.
- Use the tag_id from the ecb rather than fro the ccb. The latter is only
for target mode.
- Honor the ccb flags for tag_action when deciding whether to do a tagged
or untagged transaction.
- Re-arrange autosense completion so that it works correctly in failure
cases.
- Turn on the PI_TAG_ABLE flag so that CAM will send us tagged transactions.
This enables tagged queueing in the driver.
that the command succeeded. Sheesh! This makes CDROMs no longer cause an
instant panic at boot. Thanks to Jake Burkholder for providing a remote
test setup.
Also make device resets work, thanks to another typo.
its primary use is for the FEPS/FAS366 SCSI found in Sun Ultra 1e and 2
machines. Once the pci front-end is ported, this driver can replace the
amd(4) driver.
The code as-is is fairly stable. I've disabled tagged-queueing until I can
figure out a corruption bug related to it. I'm importing it now so that
people with these machines can (finally) stop netbooting and report bugs
before 5.3.
