[GSOC] bhyve port on ARM - weekly status report

[Mihai Carabas]

Hi,

My name is Mihai Carabas and this year's edition of GSoC I will work on
porting bhyve on ARM-based platforms (last year I've worked on bhyve
instruction caching [1]).

I've created a wiki page where I've describe the project and the milestones
[2].

This week I've started preparing the development infrastructure. We've
switched from Exynos5 development board initially proposed with FastModels
emulator, the Versatile Express board (CortexA15 model:
FVP_VE_Cortex-A15x1) because we need advanced debug features which was not
possible on the Exynos5 board without having acces to a JTAG-like device.

Next I've started creating a new config for the VersatileExpress platform
with minimal config options. I've also copied the DTS files for
VersatileExpress from linux-arm.org [3] and compiled them directly into the
kernel image. All these are pushed in my SVN repo [4].

The ARM guys have a boot-wrapper to use it with the FastModels emulator
(instead of u-boot). I've pulled this wrapper from [5] and cross-compiled
it to obtain the image of the boot-wrapper which instead will load the
FreeBSD kernel. I will come with a detailed feedback after I will manage to
boot up FreeBSD on Versatile Express emulated platform.

Thank you,
Mihai
