idata (instance data)
The term idata has two distinct meanings
for SVR5 drivers:
DDI drivers-
Beginning with DDI version 8,
specific devices are identified by
the idata and channel rather than by
device number as in earlier releases.
idata is returned by the CFG_ADD subfunction
to the
config(D2)
entry point routine. See
``Device instance''.
SDI drivers-
SDI HBA drivers use idata as shorthand
to refer to the
hba_idata_v5(D4sdi)
structure and it's similarly named predecessors.
This structure contains information
that is specific to a given instance of
a target (peripheral) device that is supported
by the HBA driver.
