For some time I have been maintaining an advanced version of the scsi_debug driver while the features in the mainline kernel version have remained unchanged. It was suggested that a patch be sent to the list against what is in the mainline (lk 2.6.17-rc5). Due to its size, the attachment is gzipped. See http://www.torque.net/sg/sdebug26.html for more information about the advanced scsi_debug driver. This patch could be considered for inclusion in lk 2.6.18 ChangeLog: - add 'virtual_gb' parameter to simulate large storage (by wrapping in dev_size_mb megabytes of actual ram) - add 'no_lun_0' parameter to skip lun 0 on each target (but still respond as required to INQUIRY + REPORT LUNS) - add well know lu support - add MODE SELECT commands support [pages: 0xa and 0x1c] - add LOG SENSE command support [pages: 0xd and 0x2f] - add READ CAPACITY (16) support - increase number of mode pages supported (to read), mainly transport specific (SAS) mode (sub)pages - add more VPD pages and extend others, including ATA information VPD page - START STOP UNIT now maintains a state machine - READ (16) and WRITE (16) cope with lbas larger than 32 bits (needed for the 'virtual_gb' parameter) - allow single command transfers up to 32 MB - more precise error (sense data) messages Signed-off-by: Douglas Gilbert <dougg@xxxxxxxxxx> Doug Gilbert
