To me it is confusing since it does not match the final location of bar3
as output by lspci. I couldn't understanding how 0x100axxxx related to bar3.

Actually that's what is strange as I can see it in info mtree -f output. See at
the end of the mail.

But typically output that
Region "0004:01:00.0 BAR 3 mmaps[0]" 0x100a0050 size=0x3fb0 cannot be DMA mapped
is not strictly correct (by chance it was not re-allocated to something else,
right?)
