query regarding BAR mapping

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

I am writing a driver for PCIe network device. I am still trying to
learn, so my question might be like a simple one as I do not
understand most of the things.

>From the BAR0 address that I read, the memory size is around 256MB.
But I have only 128MB at my disposal.

So my question is how do i map this BAR so as to access the MMIO region.

Thanks so much for your help.



Regards,
Marc Spencer
