Yes, I have tried both and both return 0xffffffff for all values.
I unloaded my driver and tried it as well. I got the same results.
I turned on my PCI Bus Analyzer and verified that the command was
accessing my device and that my device was not returning 0xffffffff, but
instead valid data.
So I guess that proves that this problem doesn't involve my driver at all?
I am going to try some other things:
1. My company has several other PCIe devices that we make. I am
going to add a different device and try to read registers from
it. If the other card works, I think I can assume that the
problem lies in some kind of incompatibility in my device.
2. If I can't read from the different device. I am going to
commandeer another host machine and install OpenSolaris 2008.11 on
it. And I will give it another go. Maybe it's my box.
