EfikaMX 2.6.31.14 Kernel Update

Update to 2.6.31.14 has been committed, compiled and uploaded for all Efika MX (TO2, TO3) versions. We encourage all users and developers to grab and test this kernel (from an SD card preferably) before installing over a PATA system.

This should be at feature parity with the last TO2 version (2.6.31.12.3) regarding little tweaks and things.

Fixes included:
* Now at 2.6.31.14
* Wireless - RT2870STA backported from Linus' tree works great. You will need the Ralink firmware from their site; it is included in the modules archive. Please read the LICENSE.ralink-firmware.txt in the /lib/firmware directory.
* Much, much better ARMv7, VFP and NEON support. Will fix graphical corruption for anyone who tried Ubuntu Lucid or new versions of Pixman and may fix some weird random crashes.

We have however noticed a couple of things which may be very annoying to some people:

* External SD card does not correctly operate on TO2 boards. We are not sure why this is; some SD cards work, some don't.
* In some rare circumstances display output on DVI-to-HDMI adapters is giving a black screen. Unfortunately the fix needs a recompile of the kernel, and breaks other DVI-to-HDMI adapters and screens, and some HDMI monitors.

We would greatly appreciate any feedback users have on this, and our forums are always open (for kernel dmesg output you can paste them into PowerDeveloper forum post for posterity - pastebin etc. expires but our forums do not. Make sure you use the [code]tag[/code]).

As always the kernel source has been published, and since it is now in git, we would greatly appreciate a merge request, patch, or any comments on any problems anyone may have.

EfikaMX Kernel Git Repo Update

You may have been watching and seen a lot of stuff being pushed into git: well, here is a summary of changes.

http://www.gitorious.org/efikamx/linux-kernel (efikamx-10.07.11 branch)

* Fixed a CPU scheduler regression since 2.6.30
* Synchronized some PMIC changes with MX51 Babbage. Should reduce power consumption by a few mW
* Pass DI clocks as platform data to IPU. Pixel clocks should be correct now, less "Input Not Supported" on your monitors
* Several updates to ARMv7 MMU and VFP/NEON handling which solves some odd problems with display corruption (some of these were applied in previous PD releases but not in the TO3 one) and TO2 boards now do not have the NEON feature flag exported to stop well designed code like pixman from plugging in functions that will crash your board.
* Reparented clocks more frugally
* Audio works but it plays half-speed for some reason

What we have now is a TO3 kernel that matches the previous TO2 PD kernel with regards to most of the esoteric patches, and should be pretty stable. We're still looking at a few other things.

We will release a build of the kernel on PowerDeveloper shortly but we have some pending problems to fix, namely that reboot/shutdown again do not act correctly and for some reason audio is played at half speed. When we resolve these issues there will be a prebuilt kernel with wireless and 3D.

In the meantime you can grab the source via git or download a tarball from the link on the right of the gitorious site (make sure you are downloading efikamx-10.07.11.tar.gz :)

After that the main task is to move in the Smartbook code.

EfikaMX Kernel Git Repository

Still in development, but here it is at last!

http://gitorious.org/efikamx/linux-kernel/commits/efikamx-10.07.11

You will find here a nice Linux kernel based on 2.6.31.14 with the latest Freescale BSP attached. We will be updating patches here. Please test it out and see how it goes for you.
