Remarks

You can use this command in a kernel-mode debugging session or in a user-mode debugging session that is attached to the UMDF host process (wudfhost.exe).

This command displays the same information as the user-mode command !wudfext.umirps.

You can use !process to get a list of all UMDF host processes, and you can use .process to set the implicit process to one of the UMDF host processes. For a detailed example, see !wdfkd.wdfumdevstacks.

Here is an example of the output of !wdfkd.wdfumirps.
