:Any planned rework of the VM? As I'm working on KGI,
:I discover that the VM of FreeBSD is very oriented for
:the paging policy.

:I wonder if dfly plans any rework of the VM that KGI could
:take benefit of to implement a totally different
:policy regarding faulting, page allocation and distribution
:of memory in alternative types of RAM: aperture, VRAM, RAM, disk...

:Thx!

Well, I don't intend to do rewrite the algorithms because I think they
are actually pretty good, but I do think that it is possible to
significantly cleanup the VM pagers API (which is what something like
KGI would have to tie into). Some work will also eventually be done
to better support the page-level I/O interface. I don't plan on doing
any of this soon, though.
