Potential applications include: * Better setup.sh script (it's long overdue, and you know it!) * Easier development of better tools for developers (see hugepage-info example) * Easier gathering of DPDK-centric system information, has potential applications in troubleshooting tools * Reduce code duplication for external tools seeking to use the same functionality (bind-unbind, cpu layout, etc) * Add cross-platform support for our scripts (see cpu-layout example now working on FreeBSD) There are a few things to mention. First of all, it's an RFC, so the fact that it's unfinished and maybe awkward comes with the territory. I am also aware of the fact that it's a Python library, that it's outside the scope of DPDK and that it's somewhat a Not-Invented-Here kind of proposition where there are a lot of externally available (and arguably much better designed and implemented) tools that do the same thing. So the first question i would like to ask is, is the community at all interested in something like this? Does it have to be part of DPDK repository? Can it be maintained in a separate repository? How do we handle updates and dependencies? I should also mention that it is *not* intended to be a replacement for udev or any other method of device binding - if anything, it's the opposite, in that it takes the whole issue out of the question and thus would make switching to udev or any other device binding easier since both internal and external tools can utilize the same Python API.
