Am i on the right track with git clone git://git.qemu.org/qemu.git ?
Yes.
scsi-block uses
read+write for READ/WRITE CDBs and SG_IO for everything else.
That sounds scary to me. On real Linux systems it is not advisable to
mix SG_IO and block device driver. At least not with optical media.
Often the block device does not learn about status changes until
the tray gets ejected and reloaded manually or by the block device
driver. If i load it by START/STOP UNIT via SG_IO, then the block
device driver believes there are no readable blocks on the medium.
Ah, I didn't know this. Probably it's because I didn't test on a
machine with a tray that can load, only a laptop. We certainly can
switch more commands from pass-through to emulated (including START/STOP
UNIT).
