DRAM Address Bit Question

[Connor Sullivan]

I have a need to increase the offset of the DRAM bank address bits. Currently (with an offset of 13) these bits overlap with the LLC set bits. I want to increase the offset to 16 to avoid this.

I know this may degrade performance. However, should I expect simulated designs to function correctly if I make the offset change without making any other changes?

When testing with BOOM, the cores end up stalling completely during Linux boot. This occurs after the software IO TLB is mapped.

Are there other changes that need to be made for this to work? Or is this not really possible with the current way the whole stack is set up?

Best,

Connor

Changing the offset seems to work fine with Rocket cores.
