I suppose nobody is paid to work > on nommu platforms, it would have to be a hobby project, right? A bunch of people are paid to work on nommu platforms, and I've worked with them a bunch, but none of them talk to linux-kernel. They find the culture toxic, insular, and categorically dismissive of their interests. For example, cortex-m is a large nommu platform on which vendors support Linux BSPs, but notice how page 8 of https://www.microsemi.com/document-portal/doc_view/132181-linux-cortex-m-users-manual points at a cross compiler toolchain from _2010_ and page 4 says they're booting a 2.6.33 kernel? I'm a bit weird in that I try to get CURRENT stuff to work on nommu, and a lot of people have been happy to consume my work, but getting any of them to post directly to linux-kernel is like pulling teeth. > But as I said, if anybody from nommu decides to maintain it in LTP, I'll try to > support him in my free time (review patches, give advices). And if nobody > stands, this patchset which removes the support in the old API will be merged > after next LTP release (in the end of January). What does the API migration do? Is there a page on it ala OABI vs EABI in arm or something?
