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=4fab9ff... https://cgit.freedesktop.org/~deathsimple/linux/commit/?h=p2p&id=f90b12d... 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.
Could be. Those patches are pretty old. They probably need to be rebased on the latest upstream p2p stuff.
