From: James Hogan <james.hogan <at> imgtec.com>
Subject: [RFC PATCH v1 00/40] Meta Linux Kernel Port
Newsgroups: gmane.linux.kernel.cross-arch
Date: Wednesday 31st October 2012 16:13:41 UTC (over 4 years ago)
This patchset adds core architecture support to Linux for Imagination's
Meta ATP (Meta 1) and HTP (Meta 2) processor cores. It is primarily an
RFC patchset to get some early feedback about what changes we need to
make, although of course all feedback is most welcome.

The patches are based on v3.6 for now, and can also be found in the
following git tree:
  git://github.com/jahogan/metag-linux.git
metag-core

Meta cores are 32-bit, hardware multithreaded, general purpose, embedded
processors which also feature a DSP instruction set, and can be found in
many digital radios. They are capable of running different operating
systems on different hardware threads, for example a digital radio might
run RTOSes for DAB decoding and audio decoding on 3 hardware threads,
and run Linux on the 4th hardware thread to manage the user interface,
networking etc. HTPs are also capable of running SMP Linux on multiple
hardware threads.

Instruction set and architecture overview documents can be found on the
following page (these currently require registration/NDA, a restriction
which was not intended and will shortly be removed):
