Subject: RE: PCIE: 32 bit prefetchable memory not getting programmed in BARs

Hi All,

In my Graphics card, it has 4 memory requirement:

a. 32 bit non-prefetchable
b. 32 bit prefetchable
c. 64 bit non-prefetchable.
d. 64 bit prefetchable

And I see a is programmed in BAR0(offset 0x10), c in BAR3(offset 0x1C), d in BAR1(offset 0x14) but b is not programmed anywhere.

So is it  an expected behaviour? 

With best,
Jay
