[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [win-pv-devel] [PATCH v2 3/3] Add XenDisk device upper filter.
From: Owen Smith <owen.smith@xxxxxxxxxx>
XenDisk intercepts and translates IOCTL_STORAGE_MANAGE_DATA_SET_ATTRIBUTES
into SCSIOP_UNMAP SRBs. Storport will pass on these SCSIOP_UNMAP requests
to XenVbd, which will create the appropriate BLKIF_OP_DISCARD requests.
XenDisk is only neccessary because Storport does not do the translation
to SCSIOP_UNMAPs.
Changes for v2:
* replace inline functions with intrinsics for byte array access/ordering
* add brackets for Length calculation
* remove SRB flags relating to queues (irrelevant for miniports)
Signed-off-by: Owen Smith <owen.smith@xxxxxxxxxx>
