26 # pshot is a pseudo driver for use in tests, together with another
27 # pseudo driver, gen_drv. These drivers' binaries are contained
28 # in the system/io/tests package (formerly known as SUNWiotu
30 # These packages are not bundled as part of Solaris however.
32 # Once installed, these drivers may be enabled by running add_drv:
34 # add_drv -i 'SUNW,pshot' pshot
35 # add_drv -i 'SUNW,gen_drv' gen_drv
38 name="pshot" class="root";
42 # How to add support for devices not included with the stock package, by
43 # certain array properties:
44 # (see pshot.h for the values of the <PSHOT_PROP_DEV.*> property names)
47 # corresponding | pshot_device_t array elements
49 # member by prop name | [0] [1] [2]
50 # ----------------------|--------------|-------------|-----------------------
51 # <PSHOT_PROP_DEVNAME> ="disk", "tape", "testdev";
52 # <PSHOT_PROP_DEVNT> ="DDI_NT_BLOCK","DDI_NT_TAPE","ddi_testdev_nodetype";
53 # <PSHOT_PROP_DEVCOMPAT>="testdrv", "testdrv", "testdrv";
56 # this example adds 3 devices that may be parented by pshot:
59 # node name: disk tape testdev
60 # node type: DDI_NT_BLOCK DDI_NT_TAPE "ddi_testdev_nodetype"
61 # compatible driver: testdrv testdrv testdrv
63 # if any of these properties are specified, then:
64 # - all the members must be specified
65 # - the number of elements for each string array property must be the same
66 # - no empty strings allowed
67 # - nodetypes (PSHOT_PROP_DEVNT) must be the nodetype name as specified in
68 # sys/sunddi.h -- caveat: see below
70 # Current implementation allows for overriding of stock devices
71 # e.g. if the "disk" device is bound to the "gen_drv" driver, you may
72 # override that with your own driver,
73 # as well as custom nodetypes
74 # i.e. if a value for <PSHOT_PROP_DEVNT> does not not match a known
75 # nodetype name, such as "DDI_NT_BLOCK" etc., then the supplied value
76 # will be used verbatim
78 # In addition, the current implementation only require that these properties
79 # be specified for a single pshot instance in order to apply globably, so it's
80 # possible to unclutter a device tree snapshot by applying these properties
81 # just to the root pshot instance with a physically single long line of
82 # property assignments:
83 # name="pshot" parent="/" <PSHOT_PROP_DEVNAME>="..",".." <PSHOT_PROP*>= ..;
