[Barrelfish-users] New Barrelfish Release

[Simon Gerber]

Dear all,

We are pleased to announce a new release of the Barrelfish OS. Along with
various bug fixes, this release includes a completely overhauled and cleaned
up ARMv7 CPU driver and support for running ARMv7 Barrelfish on ARM's Fixed
Virtual Platform simulator.

As always, you can get the latest version by cloning or pulling from our
git repository [1].

Cheers,
-- Simon

      ARMv7: Switched to ARMv7+ TLS registers.
      ARM: Removed traces of ARMv7-M and ARMv5 code.
      ARM: Removed sp804 driver, as the kernel no longer uses it.

Timothy Roscoe (5):
      Refactored ARMv7-A code. Cleaner startup process. Cleaner cross-platform portability (platform.h). Removed ARMv5. Removed ARMv7-m Removed XScale Changed kernel device paging interface and fixed bugs.
      Documentation, and cleaner dispatcher mode tracking code. Still bug with yield.
      Missing tool merge
      Missing menu.lst files
      It helps to initialize your spinlocks
