Hi, I have a 64 bit PCIe card that is connected to 64 bit PC running ubuntu (Linux ubuntu 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux). Linux enumerate this PCIe card and assign 64 bit addresses to 64 bit BARS. Problem is that higher 4 bytes of these addresses are zero, even if they are 64 bit address they lies in 32 bit range. Is it somehow possible to assign real 64 bit addresses ? This is lspci output on my ubuntu PC.
