How to access PCI configuration space in SCSI mini port driver

OSR_Community_User · June 8, 2006, 4:45am

Hi all,

I knew there are HalGetBusDataByOffset & HalSetBusDataByOffset HAL function.
But if I use these function, Public Import test will failed in HCT 12.1.

How to access PCI configuration space if driver type is SCSI miniport.

Thanks.

Hi,

Check out the White paper by Mark Roddy. Replacing HALGETBUSDATA in WINDOWS
2000. Note that in the x64 DDK HALGETBUSDATA will be an unresolved
external. This may help.

Be careful on what you want to do with the PCI configuration space.
ScsiPortGetBusData
ScsiPortSetBusDataByOffset

These are accessable only in Findadapter and AdapterControl SetRunningConfig.
If you want to read the configuration when the driver is up and running apart from these two places then there is no way to safely get the PCI config space.

Never say never. You can always sidestep SCSIPORT with a source module
compiled with DDK and then provide a proprietary interface between it and
the miniport. However, doing that will pretty well guarantee that you will
not pass WHQL, since most likely you will also have to "steal’ the PDO to
do anything.
