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
