Subject: Re: [RFC PATCH v2 00/13] nommu UML
Date: Fri, 22 Nov 2024 13:18:26 +0100 [thread overview]
Message-ID: <20241122121826.GA26024@lst.de> (raw)
In-Reply-To: <0930a0fa8e28ecaf92727229e6633278399409e7.camel@sipsolutions.net>
Maybe I'm missing something, but where does this discussion about
killing nommu even come from? Nommu is a long standing and reasonable
well maintained part of the kernel, why would anyone want to kill it
for no good reason? I know quite a lot of products shipping it.
Btw, nommu UML certainly sounds interesting to me, at least indirectly.
I have a project for next year or so for which the linux kernel library
or something like it would be useful to run an in-kernel workload as
a user space process if needed. nommu uml sounds like a really good
base for that as there basically won't be any userspace that needs
memory protection to start with.
