(See the test cases in pciutils/tests/.) Attached is a hex dump from a QEMU model using EA entries in leiu of BARs. I also attached the output of lspci, so you can see how the Region fields are displayed. Note that EA memory regions get tagged as [virtual]. I attached 2 outputs to show the truncation case I was talking about [1]. lt_size is the output when (x < 1024) is used in show_size(), whereas mod_size is the output when (x % 1024) is used. Thanks for taking a look, Sean [1] diff mod_size lt_size 8c8 < Region 0: [virtual] Memory at 80000000 (32-bit, non-prefetchable) [size=131076] --- > Region 0: [virtual] Memory at 80000000 (32-bit, non-prefetchable) [size=128K]
