Dear Joel,
I am sorry. please let me know how to download these patch
codes(source code, makefile.am http://makefile.am, pre-install.am
http://pre-install.am, etc) for mmap implementation.
At this time, I am modified makefile.am http://makefile.am for
integrating mmp source code in gsoc2011-rtems-mmu-support-project.
but, I was failed in building process.
Gedare should really comment since he mentored that. I took
the sys/mman.h from one of Chris' projects. But I can't
find it this morning.
I recall the GSoC project ended up working on MMU framework
and some target support. There was a lot of infrastructure work
to begin to think about mmap().
Chris has an implementation of some of the capabilities but I don't
recall which git repo. I thought about merging that code but it
doesn't have tests, documentation or confdefs.h support so just
brought over the header and added stubs.
Please advise me.
Best Regards.
Thomas Kim

OK great
I have an updated version of the patch. Something wasn't right
with the mskefile that showed up later. Not sure how it built
before. :(

Is this the same one that Chris has had in use before? (I

Yes. You wanted it in rtems to avoid me having to add a
prototype to
a file
to avoid a warning.
I didn't integrate his implementation but only his .h file and
stubs.
His
implementation will need the addition of tests and code in
confdefs.h.
