Message-ID: <34131.81.0.169.41.1065192660.squirrel@pluto.nixia.no> (raw)

I'd like to share memory between the uml-kernel and a user-space util
(some megabytes). I'd like this to be a file-descriptor that is mmap'ed in
both processes. What is the most nice way to do this?

The memory manager in uml can do this for me as far as I can see (but I'm
not into the internals to hack out the fd and memory maped up in the
kernel side).

Or should I just use malloc() and mmap into this area? Doesn't this fuck
up when uml goes between internal user space and kernel space, remapping
in the /tmp/foo (deleted) files? into the malloc'ed areas?

If so, this might be an issue for the dude who wants to play with gtk/x11
into the kernel then some points of implementations plays with
mmap-buffers etc.
