I don't actually know what to call frankenlibc - that was only the

Like I posed on irc, should frankenlibc be a public API, or is it just some
internal magic which makes rumprun-posix work? If the latter, I think
frankenlibc name is not too bad.
True, but the thing in front is not "posix", as there are specific
backends, currently Linux, NetBSD.
True. However, I'd rather call the product something familiar and
meaningful to users, even if slightly technically incorrect, as opposed
to inventing a new term.
Actually, we could think of a standard names for the "firmware" components
in the rumprun stack, i.e. the layer under rumpuser which consists of both
common bits (scheduler, memory allocator, ...) and platform-specific bits
(minios, bmk, frankenlibc). Anyone feeling creative?
I am starting to divide stuff up more cleanly in frankenlibc as part
of the cleanups I am doing.
The generic malloc is in the libc/generic code, while page allocation
is per platform. I have just pulled the scheduler out of librumpuser
into libc/thread, although the mutex code needs splitting out still to
abstract it a bit better. This means that librumpuser is not exposing
threading stuff which should make the _lwp support nicer as it will be
using internal interfaces.
So the structure is librumpuser -> frankenlibc -> platform although
currently frankenlibc generic and platform are built into the same
libfranken.a, but they are split in the code (libc/linux and
libc/netbsd is the platform code).
Right, so in your terminology "frankenlibc + platform" is what I called
"firmware".
Note also buildrump.sh/bmk-common. I have some more unpushed changes
for bmk-common, though, like I wrote earlier, I'm not determined if I
got them right enough push them.
But we still need some official names.
