[SCSI] scsi_debug: Implement support for DIF Type 2

2009-10-02T14:47:17Z

Add support for 32-byte READ/WRITE as well as DIF Type 2 protection. Reject protected 10/12/16 byte READ/WRITE commands when Type 2 is enabled. Verify Type 2 reference tag according to Expected Initial LBA in 32-byte CDB. Signed-off-by: Martin K. Petersen Acked-by: Douglas Gilbert Signed-off-by: James Bottomley

scsi_debug: Add support for physical block exponent and alignment

2009-06-21T16:03:54Z

This patch adds support for setting the physical block exponent and lowest aligned LBA in the READ CAPACITY(16) response. The B0 VPD page is adjusted accordingly. Signed-off-by: Martin K. Petersen Acked-by: Douglas Gilbert Signed-off-by: James Bottomley

[SCSI] scsi_debug: DIF/DIX support

2009-03-12T17:57:55Z

This patch adds support for DIX and DIF in scsi_debug. A separate buffer is allocated for the protection information. - The dix parameter indicates whether the controller supports DIX (protection information DMA) - The dif parameter indicates whether the simulated storage device supports DIF - The guard parameter switches between T10 CRC(0) and IP checksum(1) - The ato parameter indicates whether the application tag is owned by the disk(0) or the OS(1) - DIF and DIX errors can be triggered using the scsi_debug_opts mask Signed-off-by: Martin K.

[SCSI] struct device - replace bus_id with dev_name(), dev_set_name()

[jejb: limit ioctl to returning 20 characters to avoid overrun on long device names and add a few more conversions] Signed-off-by: Kay Sievers Signed-off-by: Greg Kroah-Hartman Signed-off-by: James Bottomley

[SCSI] replace FUNCTION with func

2008-07-27T14:31:49Z

[jejb: fixed up a ton of missed conversions. All of you are on notice this has happened, driver trees will now need to be rebased] Signed-off-by: Harvey Harrison Cc: SCSI List Signed-off-by: Andrew Morton Signed-off-by: James Bottomley

[SCSI] scsi_debug: add support for rotation speed

2008-07-12T13:22:30Z

Add support for VPD page b1 to scsi_debug SCSI VPD page b1 reports the nominal rotation speed of the device. Since scsi_debug is ram-based, claim to be a non-rotating medium. Signed-off-by: Matthew Wilcox Acked-by: Douglas Gilbert Signed-off-by: James Bottomley

[SCSI] scsi_debug: Runtime-configurable sector size

2008-07-12T13:22:24Z

Make scsi_debug sector size configurable at load time instead of being a #define. Handy for testing 4KB sectors. Signed-off-by: Martin K. Petersen Acked-by: Douglas Gilbert Signed-off-by: James Bottomley

block: make queue flags non-atomic

2008-04-29T12:48:33Z

We can save some atomic ops in the IO path, if we clearly define the rules of how to modify the queue flags. Signed-off-by: Jens Axboe

[SCSI] scsi_debug: remove unnecessary function declarations

2008-04-07T17:19:07Z

This patch removes function declarations with moving some functions. This cleans up them a bit to silence checkpatch.pl. There is no functional change. Signed-off-by: FUJITA Tomonori Acked-by: Douglas Gilbert Signed-off-by: James Bottomley
