Hi, As far as I've been able to gather, the open source version of DPDK does not include bare-metal support. However, I'm not very knowledgeable on DPDK, especially on code which I cannot read myself, so maybe someone else can answer that better. I do know something about rump kernels, though. One of main future use cases I see is indeed to have them run on bare metal and therefore allow to continue use essential kernel-only implemented features but still get rid of the prehistoric OS overhead layer. I have good reason to suspect that running rump kernels this would be easy, but as far as I know, no one has done the necessary work, at least not for x86. Unless the bare-metal version of DPDK provides a suitable portability layer, you'd be looking at implementing the rump kernel hypervisor interface for bare metal (or bare firmware ?-). In such a case, you might find using that using also the device layer from a rump kernel is the shortest path to initial success, with migration to DPDK only after reaching stability in that setup. But, that's getting quite off-topic for this list. Contact me off-list if you are serious about putting effort into the above. - antti
