Hi,
Trying to answer some question raised by comments in the current code.
- The card should be able to DMA to anywhere in a 64-bit address space.
It is set to 32bit DMA by default. A bit has to be set to turn on 64-bit.
Which bit? As far as I see, TLB entries are still 32bit. So the pages can't be in 64bit space, right?
