Hi,
right now i got the chance to play a little bit with PCIe. I read some
parts of the spec
and was interessted what my PCIe devices can do. I also found out that
pcidump can
not display the Enhanced Capabilites.
This patch enables pcidump to display them.
I did not find a good list of descriptions for the different
capabilities, the one im using
in this patch was taken from the linux kernel. Is it possible to get a
complete list
somewhere?
Here is an example output:
# pcidump -v
Domain /dev/pci0:
