scsi: add xfer mode
Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
scsi: move dinfo to SCSIDevice
scsi: move status to SCSIRequest.
Also add and use the scsi_req_complete() helper function for calling thecompletion callback.
scsi: create common SCSIRequest structure.
Rename the SCSIRequest structs in scsi-disk.c and scsi-generic.c toSCSIDiskReq and SCSIGenericReq. Create a SCSIRequest struct and movethe common elements over.

scsi: move request lists to QTAILQ.
Changes: * Move from open-coded lists to QTAILQ macros. * Move the struct elements to the common data structures (SCSIDevice + SCSIRequest). * Drop free request pools. * Fix request cleanup in the destroy callback....
scsi: move SCSIRequest management to common code.
Create generic functions to allocate, find and release SCSIRequeststructs. Make scsi-disk and scsi-generic use them.
scsi: move scsi command buffer from SCSIGenericReq to SCSIRequest.
scsi: move blocksize from SCSIGenericState to SCSIDevice
scsi: add scsi-defs.h
Largely based on <scsi/scsi.h> from linux. Added into the tree so wecan use the defines everywhere, not just in scsi-generic.c (which islinux-specific).
scsi: move type from SCSIGenericState to SCSIDevice
scsi: add request parsing helpers to common code.
Add helper functions for scsi request parsing to common code. Gettingcommand length, transfer size, and linear block address is handled.
Fix qemu_free use in scsi-generic.c
scsi-generic.c is using free() instead of qemu_free().Fix it.

scsi: move scsi-disk.h -> scsi.h
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...
Implement scsi device destruction
qdev/scsi: add scsi bus support to qdev, convert drivers.
Adding scsi disks via -device works now, i.e. you can do:
-drive id=sda,if=none,......

new scsi-generic abstraction, use SG_IO (Christoph Hellwig)
Okay, I started looking into how to handle scsi-generic I/O in thenew world order.
I think the best is to use the SG_IO ioctl instead of the read/writeinterface 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 anordinary host block device, the block API is abused in a couple of annoyingways:
- 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 throughthe scsi-generic interface.
Previous patch introduced tape SCSI commands management, this oneimprove 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 thedevice is a tape.
Some issues remain when the application reading the tape tries to go...
scsi-generic: correct 6-bytes commands transfer length (Laurent Vivier)
According to SCSI documentation, for 6 bytes commands (READ,WRITE), if transfer length is 0 it specifies 256 blocks.

DESCRIPTION The memset() function fills the first n bytes of thememory area pointed to by s with the constant byte c."
