Jeff,
Here is another shot at adding MODE SELECT to
libata. I have used sat-r06, sbc-3 and spc-4 as
a guide. Compliance on the ATA side has some issues:
- no mechanism to issue 2 or more ATA commands
when translating a single SCSI command [in the
upstream branch, there have been patches ...]
- relies on the dev->id array (IDENTIFY DEVICE response)
always being up to date. Despite assurances I cannot
see how that is the case when multiple hosts
(initiators) can access a SATA disk.
This patch is broken into two parts and is against
libata-dev's upstream branch:
1) strengthen MODE SENSE processing and make
default mode pages visible within libata-scsi.c
2) add MODE SELECT SCSI command support.
Thanks for splitting it up. I'm going to mess around with the best way
to issue multiple commands, and hold on to your patch #2 until that happens.
Jeff
