[Qemu-devel] [PATCH 00/20] SCSI subsystem improvements |
Date: |

This series includes the following improvements to the SCSI subsystem:
1) introduction of SCSIBusOps that generalize the existing
command_complete callback;
2) widespread use of the SCSIRequest abstraction, with simpler memory
management (refcounting) and with various common idioms converted into
simple C functions instead of duplicating them all over the place;
3) support for autosense.
Some patches are from Hannes Reinecke's megasas patchset posted last
November, forward ported and applied to the new vSCSI controller as
well.
Testing:
- RHEL6.1 install complete to scsi-disk with lsi, from scsi-generic CD
- iozone run with lsi on scsi-disk target
- RHEL6.1 install to usb-msd from IDE CD hangs (probably) when formatting
the USB disk, gets I/O errors even earlier without the series
- RHEL6.1 install started with vscsi, from scsi-generic CD including
playing with opening/closing the tray (to exercise autosense), plan to do
a complete test later if no one beats me to it
esp is only compile tested.
Hannes Reinecke (4):
scsi: Use 'SCSIRequest' directly
scsi: Update sense code handling
scsi: Implement 'get_sense' callback
scsi-disk: add data direction checking
Paolo Bonzini (16):
scsi: add tracing of scsi requests
scsi-generic: Remove bogus double complete
scsi: introduce scsi_req_data
scsi: introduce SCSIBusOps
scsi: reference-count requests
lsi: extract lsi_find_by_tag
scsi: commonize purging requests
scsi: introduce scsi_req_abort
scsi: introduce scsi_req_cancel
scsi: use scsi_req_complete
scsi: do not call send_command directly
scsi: introduce scsi_req_new
scsi: introduce scsi_req_kick
scsi: introduce scsi_req_get_buf
scsi: make write_data return void
scsi-generic: Handle queue full
