SAM Adapter Device Driver ioctl Commands

Various ioctl operations must be performed for proper operation of the adapter device driver.

The ioctl operations described in the following topics are the primary set of ioctl commands that the adapter device driver must implement to support device drivers. Many of these ioctl operations are relevant to all SAM physical transport types, however, some operations are relevant only to a specific transport type. Other ioctl operations might be required in the adapter device driver to support, for example, system management facilities and diagnostics.

Attention: The adapter device driver ioctl operations can only be called from the process level. They cannot be run from a call on any more favored priority levels. Attempting to call them from a more favored priority level can result in the system ending abnormally.
