Try a different system, if you can. It might be something goofy happening at the PCIe bridge.
It might be an IOMMU or cache getting involved somewhere. -- Garrett Adam Chunn wrote:

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. -Adam ------------------------------------------------------------------------ _______________________________________________ driver-discuss mailing list driver-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/driver-discuss
