How to Use SrbExtension

WINDBG
1

Hi,

I am new to windows driver development. Any help would be highly appreciated.

I am trying to use SrbExtension memory of 4k(mentioned in Hw_initialisation_data and port_configuration_information).

When Io is initiated, i tried to access the memory provided by SrbExtension in HwBuildIO function of my driver. I tried to get physcial address by calling StorPortGetPhysicalAddress.

This results in BSOD(0x000000D1) in module storport.sys.

What is the mistake i am doing? Is there any other to use srbextension memory?

Thanks,
Amogha

Hi,

Make sure you pass “NULL” for Srb parameter in StorPortGetPhysicalAddress
