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.
Region 0: Memory at fddff000 (64-bit, non-prefetchable) [size=4K]
Region 2: Memory at fd000000 (64-bit, prefetchable) [size=8M]
Region 4: Memory at fc800000 (64-bit, prefetchable) [size=8M]
Regards,
Flyingbee.
