The controller is handling them, calling scsipi_done() here will end up in the
xfer being scsipi_done()'ed a second time when it completes in the controller
code. In addition, the way the loop was done here would end up in an infinite
loop, because the channel kernel thread needs to run to remove a command from
this queue.
scsibusdetach(): scsipi_done() all commands from periph_xferq. The controller
is already gone, and these commands will never complete.
Shut down the channel (which will cause the kenrel thread to exit) after
detaching the childs, as they will need the kernel thread for
scsipi_wait_drain().
Fix kernel hang or deadlock when detaching devices (either by scsictl detach
or unplug) with active commands.
OS needs such a hack, and the same drive works fine on Suns -- and is much
more likely to be a bug in the host adapter driver (which is corroborated by
the PQUIRK_NOLUNS).
ready. This avoids gratuitously starting the motor on floppy and CD-ROM
drives, and eliminates the need for the audio playing test in cdopen().
Therefore, also remove PQUIRK_NOSTARTUNIT.

be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
fine at U2W, but barf at U160, with different controllers. Unfortunately
sometimes just being initialized at U160 does the trick, so setting them
to lower speed in the BIOS may also be needed.
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals
kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)
based on work done by Jonathan Lemon for FreeBSD

- Use the plain words 'disk' and 'tape' instead of 'direct' and 'sequential'.
- Media status will be printed in the frontend, so don't bother with it.
- Don't bother printing the SCSI version, which is fixed these days, or the
numberic device type.
This eliminates problems where the underlying interrupt handler isn't the
specific layer calling scsipi_complete() for a given scsi transaction.
This avoids deadlocks where the kthread that called the autoconf routines
to configure a scsibus shouldn't be the one put to sleep waiting on a
scsipi_complete (only the scsibus's kthread should be doing that).
To avoid jitter this will force the scsibus's to probe in the order they
run through autoconf (so machines with multiple bus's don't move sd* devices
around on every reboot).
This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
