Subject: Re: Error reading from DAT (fwd)
Date: Mon, 11 Oct 1993 03:02:39 -40962758 (WST)

Some tapes won't do anything until you tell them to load.
Other tapes think that being asked to load is a great excuse to
make the next command return a "unit attention" (media changed) error.
Since we need to do the load, throw in a dummy instruction to cop the
error.

specifically for DEC DAT drives.

1/ fix bug where cd0a was unusable because it was compared against
the number of 2k blocks not the number of 512byte blocks.. gave
an error for all reads past 1/4 way through the disk (cd0d was ok).

2/ fix open code so that it now notices if a disk has been changed
and updates the disklabel.

3/ use the new error handling code from st.c

4/ start adding stuff to get ready for using cd_scsi_cmd from
cd_start (like is done in st and sd)

5/ more general cleanups including making dmesg report
sector size of disk.. (believe it or not SUN drives use 512 byte)

06a1e2ded2 Increase the timeout from 2000 counts to 6000 counts, reported by someone 
on the net (I lost the mail).  This should fix some units not showing up
during probes.

968d6ea058 The dynamically allocated struct's where not getting properly initialized 
as malloc memory is NOT zerod.  Added bzero's after the malloc calls
to make sure that things are initialized.

f03cb6c766 The scsi cd.c driver is now fully dynamic. You can change the lines 
in your config file from:
device          cd0
device          cd1
...
device          cdn
to either
device          cd0
or
psuedo-device   cd0

The driver now dynamically allocates all per unit dependent structs, so it
will never run out of units (okay, so now we need 32 bit device major/minor
numbers!).  It will allocate unit numbers as it needs them.

5c8830eef2 Changed the delay from 100 seconds to 20 seconds if you don't have scsi 
dump code.

65119574e4 First pass fixes to start using malloc structures for all per unit 
data.  cd_data is now malloced on a per unit basis.

Protected all if ({scsi,cd}_debug).... with #ifdef CDDEBUG to reduce the
the size of the kernel when not debugging.

57dd4ca1b2 Several fixes to the st driver, for density detection and selection. No 
longer have to do the st -f /dev/rst0 blocksize 0 on dat drives!

2b40491738 Fixed printf if you are using SCSI_DELAY to allow the scsi bus to 
settle down after the reset.

a3e4335498 Revised drivers from Julian. Support for generic scsi. Fixed scsi tape (st.c) 
problems with respect to multiple tar files on one tape.  Now uses malloc
of data structures to reduce static kernel size.

296cbdb15b Fixed printf's so that they announce them selfs correctly (ie aha%d: before 
every error message and every probe message).

e5cf9f6134 Update scsi code to the latest from Julian. This code is now identical 
to the last copy from Julian.  After this commit I will be commiting the
local fixes and makeing diffs to send back to Julian so he can update his
code.

Subject: Re: timeout diffs

Here are the diffs to take the scsi stuff to my latest tree from what
Nate and you received..

the changes remove all the local timeout stuff and use (un)timeout(),

903a4691a3 Removed tabs from the front of XXU: messages to make it fit the other 
messages closer.  Added missing new line to the message about to many
scsi cd drives.

d97875d4b0 Removed PATCHKIT headers and updated our sources to Julian's with 
our patches back in.  Major changes to the Bustek driver and the
Tape driver, the rest are minor.
