FatdogArm on Odroid-XU4

A kind gentleman who goes by the nickname of "pjf" on Puppy Linux forum gave me an Odroid-XU4 to play with.

As a result, FatdogArm now supports Odroid-XU4. The support is pre-eliminary - it's mainly kernel supports; the usual hardware acceleration stuff aren't supported yet.

The kernel package for Odroid-XU4 (and also XU3 - these two are software-compatible with each other) is here: http://distro.ibiblio.org/fatdog/arm/releases/beta4/kernel-packages/, or on any of ibiblio's mirrors.

This work is still in flux, though, as I'm still tweaking the kernel. It's now my 3rd compile. It may change. And while you can find beta4 SFS there, I haven't really released it and I may still make some changes soon.

Odroid-XU4 is a little machine that could. The SoC is Samsung Exynos 5422. It comes with 8 cores (ARM BIG.little architecture - 4x 2GHz cores, and 4x 1.7GHz cores), *ALL( of which can be run simultaneously under HMP mode.

It is so powerful that:
---
a) I can decode h.264 1080p video and render it to 1080p, with AAC audio, using software only (no hardware acceleration).
b) I can watch youtube using html5, with audio, without any stutter.

I've never been able to do this in my previous board. It is the fastest little board I've ever used, bar none.

It comes with a cost though. All those speed doesn't come from nothing. It is no longer fanless like Odroid-U2; XU4 comes with a fan. The power supply now can provide juice up to 4A - but this probably to support 2 USB3 ports on its board too.

PS: I used 3.10.y kernel. The 4.2 kernel is marked as EXPERMENTAL by hardkernel and currently lacks many of the fine improvements you can find in 3.10, like sound, and HMP support. It was created to be able to boot Debian server, but I find that even for server work, this is no good because it lacks the ability to schedule the cores properly. And furthermore, it seems to have been abandoned (last update is Aug 2015, while 3.10 is updated just a week ago).

PPS: An oh, on the same URL, you can find official Raspi2 kernel packages too. This is my official kernel packages, which I built from source, and of which I can also supply its kernel source SFS. The berryboot-based kernel are still available in its old link but I'm going to take it down soon.
