 Hi Thomas



Yes, your proposal it the perfect one, also the most complicated one. I
was thinking of that one as well, but we did not have enough time for that
in our 1.8 timeframe.

In the long run, I agree with you to implement EAL function to access PCI
config space directly. I will try to put it in our plan as soon as
possible, if no objections.



For now, I think the quickest and easiest way might be to write out a
script of using ‘setpci’, the Linux command. It is harmless for our code
base, and we can remove it when we have better choice. What do you think?



Thank you very much for the great comments on this topic! I really like it!

Did you make any progress on this ?
Actually, looking at Stephen patches (
http://dpdk.org/dev/patchwork/patch/3024/), I think we could go with this
approach once both uio and vfio are fine.
