device_test_p2p() return true if two devices can peer to peer to
each other. We add a generic function as different inter-connect
can support peer to peer and we want to genericaly test this no
matter what the inter-connect might be. However this version only
support PCIE for now.
What about something like these patches:
https://cgit.freedesktop.org/~deathsimple/linux/commit/?h=p2p&id=4fab9ff69cb968183f717551441b475fabce6c1c

They are a bit more thorough.
Those new functions seem to have a lot of overlap with the code that is
already upstream in p2pdma.... Perhaps you should be improving the
p2pdma functions if they aren't suitable for what you want already
instead of creating new ones.
Yeah, well that's what I was suggesting for the very beginning :)
But completely agree the existing functions should be improved instead
of adding new ones,
Christian.
