Hi,
This is the new version of the ATAPI pass through patches.
What's new from the v3 ?
- applied Christoph and Juan comments
- made some part of ide.c public and added new files:
- ide.h some defines, structures and function declarations
- atapi-defines.h atapi related defines and function to retrive name
from the command
- atapi-data.c some data tables
- atapi-pt.h atapi pass through structures and public functions
- atapi-pt.c atapi pass through implementation
I hope this one is alright.
Thanks.

Add some missing ATAPI protocol defintions, and fix up some whitespaces
and comments on the way.

ATAPI pass through code is enabled when the block device is a scsi
device. So we have to guess if the block device is a scsi device in
cdrom_open().

* [Qemu-devel] [PATCH 7/7] atapi: introducing atapi pass through
2009-08-07 17:33 ` [Qemu-devel] [PATCH 6/7] atapi: made some part of ide.c public and moved some part to atapi Alexandre Bique

From: Alexandre Bique @ 2009-08-07 17:33 UTC (permalink / raw)
To: qemu-devel; +Cc: Alexandre Bique
This patch introduce atapi pass through. The pass through code is used
by default when the underlying block is a scsi device.
This brings 1 new option to the command line interface:
-cdrom-allow-fw-upgrade which allow to pass through the firmware
upgrade which is blocked by default. See the WRITE_BUFFER command for
more details.

should be controllable on a per-device basis.
