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.

* [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 @ 2009-08-07 17:33 ` Alexandre Bique 0 siblings, 0 replies; 10+ messages in thread 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.
