Description Philipp Mergenthaler 2002-04-07 13:40:02 UTC

This patch adds the ioctls CDRIOCREADSPEED and CDRIOCWRITESPEED to the
scsi driver, which allow to set the drive's speed.

How-To-Repeat: 
To test this, you may want to use the patch to cdcontrol from
PR kern/35512.

To test whether your drive offers this capability, use
  camcontrol cmd cd0 -v -c 'bb 0 v:i2 0:i2 0 0 0 0 0 0' 2000
where the last number (here: 2000) is the speed in kB/s.
(But apparently there are drives which have a vendor specific command
for this and for which this patch may not work.)

Patch needs some reworking to fit scsi_cd/scsi_all semantics...  will analyze 
some more and consider committing this modulo fixes.

Modified patch was committed in scsi_cd.c v1.67 along with various changes 
to unify the API with atapi-cd.  The userland utils burncd and cdcontrol 
were also updated.
