| # pshot is a pseudo driver for use in tests, together with another |
| # pseudo driver, gen_drv. These drivers' binaries are contained |
| # in the system/io/tests package (formerly known as SUNWiotu |
| # and SUNWiotux). |
| # These packages are not bundled as part of Solaris however. |
| # |
| # Once installed, these drivers may be enabled by running add_drv: |
| # |
| # add_drv -i 'SUNW,pshot' pshot |
| # add_drv -i 'SUNW,gen_drv' gen_drv |
| # |
| |
| name="pshot" class="root"; |
| |
| |

| # How to add support for devices not included with the stock package, by |
| # certain array properties: |
| # (see pshot.h for the values of the <PSHOT_PROP_DEV.*> property names) |
| # |
| # |
| # corresponding | pshot_device_t array elements |
| # pshot_device_t | |
| # member by prop name | [0] [1] [2] |
| # ----------------------|--------------|-------------|----------------------- |
| # <PSHOT_PROP_DEVNAME> ="disk", "tape", "testdev"; |
| # <PSHOT_PROP_DEVNT> ="DDI_NT_BLOCK","DDI_NT_TAPE","ddi_testdev_nodetype"; |
| # <PSHOT_PROP_DEVCOMPAT>="testdrv", "testdrv", "testdrv"; |
| # |
| # |
| # this example adds 3 devices that may be parented by pshot: |
| # dev1 dev2 dev3 |
| # ---- ---- ---- |
| # node name: disk tape testdev |
| # node type: DDI_NT_BLOCK DDI_NT_TAPE "ddi_testdev_nodetype" |
| # compatible driver: testdrv testdrv testdrv |
| # |
| # if any of these properties are specified, then: |
| # - all the members must be specified |
| # - the number of elements for each string array property must be the same |
| # - no empty strings allowed |
| # - nodetypes (PSHOT_PROP_DEVNT) must be the nodetype name as specified in |
| # sys/sunddi.h -- caveat: see below |
| # |
| # Current implementation allows for overriding of stock devices |
| # e.g. if the "disk" device is bound to the "gen_drv" driver, you may |
| # override that with your own driver, |
| # as well as custom nodetypes |
| # i.e. if a value for <PSHOT_PROP_DEVNT> does not not match a known |
| # nodetype name, such as "DDI_NT_BLOCK" etc., then the supplied value |
| # will be used verbatim |
| # |
| # In addition, the current implementation only require that these properties |
| # be specified for a single pshot instance in order to apply globably, so it's |
| # possible to unclutter a device tree snapshot by applying these properties |
| # just to the root pshot instance with a physically single long line of |
| # property assignments: |
| # name="pshot" parent="/" <PSHOT_PROP_DEVNAME>="..",".." <PSHOT_PROP*>= ..; |
