WMI for miniport

NTDEV

Are WMI_REQUEST_BLOCK sent to a miniport driver dependent only on
setting
WmiDataProvider in the PORT_CONFIGURATION_INFORMATION structure of the
miniport ?

I guess you are talking of SCSI miniport here. If yes, there are a few things you need to get the WMI working in a SCSI miniport.

  1. In your HwScsiFindAdapter routine, set PPORT_CONFIGURATION_INFORMATION->WmiDataProvider TRUE
  2. Prepare and compile your mof file and embed the compiled file (.bmf) in your .rc file
  3. Handle WMI SRBs that scsiports sends to your miniport using the helper API from SCSIWMI.LIB

Checkout the miniport sample in the DDK on how to use the API from SCSIWMI.LIB

There is a presentation available on the Microsoft website.
