Accessing other PCI device

NTDEV

Hi All,

I am writing a Streaming WDM driver and I wanted to access the Base Physical
address of a different (with different Vendor Id and device ID) device from
the WDM driver. I tried HalGetBusDataByOffset but this function doesn’t seem
to work. Id there a way I can access the device ?.

Thanks
Nattu

Generally, this cannot be done in reliable way due to being unable to
synchronize your code with the “main” driver’s code.
