drive cleanup fixes.

Changes: * drive_uninit() wants a DriveInfo now. * drive_uninit() also calls bdrv_delete(),
so callers don't need to do that. * drive_uninit() calls are moved over to the ->exit()
callbacks, destroy_bdrvs() is zapped. * setting bdrv->private is not needed any more as the...

qdev/scsi: add scsi bus support to qdev, convert drivers.

  • Add SCSIBus. * Add SCSIDeviceInfo, move device callbacks here. * add qdev/scsi helper functions. * convert drivers.

Adding scsi disks via -device works now, i.e. you can do:

new scsi-generic abstraction, use SG_IO (Christoph Hellwig)

Okay, I started looking into how to handle scsi-generic I/O in the
new world order.

I think the best is to use the SG_IO ioctl instead of the read/write
interface as that allows us to support scsi passthrough on disk/cdrom...

Add specialized block driver scsi generic API (Avi Kivity)

When a scsi device is backed by a scsi generic device instead of an
ordinary host block device, the block API is abused in a couple of annoying
ways:

- nb_sectors is negative, and specifies a byte count instead of a sector count...

scsi-generic: correct error management

this patch allows to fully use a tape device connected to qemu through
the scsi-generic interface.

Previous patch introduced tape SCSI commands management, this one
improve error case management:

- the SCSI controller command completion must be called with the status...

scsi-generic: decode correctly SCSI tape commands (Laurent Vivier)

This patch allows to use a "real" SCSI tape with qemu using
"-drive /dev/sgX,if=scsi".

It allows to decode correctly transfer length when the type of the
device is a tape.

Some issues remain when the application reading the tape tries to go...
