to access it. setdelayed() actually ORs the bits in `idelayed' into
`ipending' and clears `idelayed'.
Call setdelayed() every (normal) clock tick to convert delayed
interrupts into pending ones.
Drivers can set bits in `idelayed' at any time to schedule an interrupt
at the next clock tick. This is more efficient than calling timeout().
Currently only software interrupts can be scheduled.
It closed the wrong device (usually the B partition instead of the C

The latter case should be the default. DUMMY_NOPS should be the default

there are no delays in writertc()) and several FASTER_NOPs slowing down

Support disk slices. This involves mainly replacing inline code with
function calls. Support for ST506 drives is temporarily broken since
the `setgeom' arg to dsopen() is not implemented completely enough to
use. The `setgeom' arg will go away and ST506 drives will be supported
in another way. A large amount of dead code is left in wdopen() as a
reminder of the problems here.
Close the device in wdsize(). Open tracking was broken on all drives
with a swap device.
Remove support for soft write protection. There are no ioctls to set
it. It was used to disable writing to unlabelled disks, but we want
to support writing to foreign partitions on unlabeled disks.
Use generic dkbad routines to do about 2/3 of the work for supporting
bad144.
Improve disk statistics: estimate 4MB/sec instead of 8MB/sec for

fix dk_xfer[] (it counted sectors, not transfers); keep the estimate
dk_seek[] = dk_xfer[] (was sectors, is now transfers); only count
words actually transferred (the count is still too high after a
failed write and after retries). Remove wdxfer[].
Fix indentation in wdattach(). Fix resulting botched printing of the

Dropping into the debugger when a break comes down the serial line is a

For those where it was easy, drivers were also fixed to call
dev_attach() during probe rather than attach (in keeping with the
new design articulated in a mail message five months ago). For
a few that were really easy, correct state tracking was added as well.
The `fd' driver was fixed to correctly fill in the description.
The CPU identify code was fixed to attach a `cpu' device. The code
was also massively reordered to fill in cpu_model with somethingremotely
resembling what identifycpu() prints out. A few bytes saved by using
%b to format the features list rather than lots of ifs.

This version of matcd implements the rest of the key ioctls related to
playing audio CDs and reading table of contents information from any
type of disc.
This update also corrects several problems detected since the original
version 1(10) was released. These include:
1. Jordons report on the kernel -c string problem.
2. A problem with the driver being confused by other types of
devices located at addresses it probes.
3. An old CD TOC wouldn't always be cleared after a disc change.
4. Cleaned up code so -Wall yields no warnings on 2.0 and later.
5. A problem with drive getting out of sync with the driver when
changing between CD-Data and CD-DA.
There have only been two reports from the field relating to problems
so either the first release isn't really being used or doesn't have
many problems.
If there are any problems with this submission, please let me know.
