That was the good news. The bad news is that bad144 is a proper mess,
and I don't have time to fix it now, so you will probably not be able to
use it anyway.
Sorry guys, go out and buy a 100Mb IDE drive and a paddleboard :-(
If somebody wants to pick up on this: bad144 needs to learn how to
stay inside our slice of the disk. That's the trick.
Somehow, I don't think this stuff was tested at all! :-(
I really hope that it actually works, though my hopes are steadily diminishing.
Anyone with 27xx/28xx boards in -current is *strongly encouraged* to give this
stuff a shot! Otherwise, I suspect that we'll be punting this out of
2.0. I haven't found a single part of Justin's commit that wasn't broken
in some way.
Remove bogus declaration of Debugger(). Call Debugger() even if DDB is
not defined, but still call panic() after Debugger() returns, although
most other SCSI drivers just call Debugger().
with the current default exception (un)mask. There should be no such
processes unless you change the mask. Someday the mask should be
changed to the IEEE default of everything masked. The npx state
gets saved so that it can be checked and this may have the side effect
of fixing a bug that was reported for 1.1.5. (npx exceptions may
sometimes leak across exits and clobber another process. I can't see
how this can happen.)
Get some missing/wrong declarations from headers now that the headers
have them.
of the 1.1.5 driver, a recent version of the NetBSD driver, Andres'
transmission start threshold code, and all other relavent changes to the driver
since it was brought into 2.0. The multicast support from NetBSD has not be
folded in yet. I've tested it under high loads for two weeks and it is now
robust enough to be included in the GENERIC kernel.

Fix mcd_subchan to return position, inspired by idea from
bugress@s069.infonet.net, but different implementation.

quite a while.

seconds are spent busy-waiting.

Rename `timer0_prescale' to `timer0_prescaler_count' and maintain it
correctly. Previously we lost a few 8253 cycles for every "prescaled"
clock interrupt, and the lossage grows rapidly at 16 KHz. Now we
only lose a few cycles for every standard clock interrupt.
Rename `*_divisor' to `*_max_count'.
Do the calculation of TIMER_DIV(rate) only once instead of 3 times each
time the rate is changed.
Don't allow preposterously large interrupt rates. Bug fixes elsewhere
should allow the system to survive rates that saturate the system, however.
Clean up declarations.
Include <machine/clock.h> to check our own declarations.
