I'm using lspci from pciutils-3.1.2 on an embedded powerpc platform. The platform logic "fixes" up the BAR memory addresses to show the true 36-bit physical address mapped to the CPU. If I use the lspci linux-proc access method (-A linux-proc) only 32-bits of the memory BAR physical address is displayed, with the truncation occurring on the right. Example: ... Memory at e0030000 (64-bit, non-prefetchable) ?disabledÙ ... This should be shown as: ... Memory at 0000000e00300000 (64-bit, non-prefetchable) ?disabledÙ ... I poked around the lspci source and think I have found the problem. In lib/types.h, the definition for PCIADDR_T_FMT is not large enough to accommodate 64-bit addresses. I've appended my change below. This problem is only seen using the linux-proc access method. linux-sysfs works OK. I do not know if there are other implications to this change but it fixes the problem above.
