MSM/QSD hardware adaptation

Nexus3.jpg Meego-handset-nexusone-portrait.jpg

This page was inspired by this link http://www.android-devs.com/?p=152 which has instructions to run Debian natively on the Google Nexus One handset. With a number of vendors shipping kernel source with MSM/QSD hardware this gives the possibility of running MeeGo on these platforms. As usual open drivers will be key to success.

This port is not a work in progress and not meant for end user installation. The following details are for MSM/QSD porting effort and no end user images are available.

See details of how to start developing for your device here, http://android.modaco.com/category/363/device-specific/

Nexus One

Initial Port

basic msm_fb with mesa

The picture above was taken with the 18.09.10 daily trunk handset UX, mesa packages added to provide swrast-DRI, ELG and GLESv2. Kernel is a stock google 2.6.32 msm kernel. Touch is working but needs rotating. 

sudo ./fastboot -c 'root=/dev/mmcblk0p1 rw rootfs=ext3 init=/sbin/init rootwait noinitrd' boot zImage

WARNING : First boot can take up to 5 mins, second boot should be around 75 seconds

WARNING : UI is not hardware accelerated so don't expect the full user experience

libEGL and libGLESv2

As we know vanilla X and software GLES works but we need hardware libEGL and libGLESv2 for better performance.

I pulled libEGL.so, libGLESv2.so and libGLESv1_CM.so from my Nexus /system/lib along with the supporting /system/lib/egl files lib***_adreno200.so as the system/lib files are just stubs into the lib/egl files.

After booting .xsession_errors reported liblog.so not found when loading mcompositor. pulled that from Nexus.

libcutils.so was not found next then 'libc.so ELF version does not match current version' was reported. The libc.so in /usr/lib was a pointer to /lib so I just copied the /lib file to /usr/lib.

Now libutils.so and libz.so were not found and were pulled from the nexus.

Now here is the kicker, 'undefined Symbol __sF' in libc.

This is because the Android libs I pulled have been built with Bionic libc and I cannot use that as that would break the rest of MeeGo.

So the question is can we arrange for bionic and glibc to coexist or is this the end of the road?

After talking to a few guys on xda I think this avenue is closed - unless you know better. http://forum.xda-developers.com/showthread.php?t=764255&page=6

WIP to build this driver on maemo OBS - http://pastebin.com/pDd6MbKD

Just had this email in from Jordan Crouse at code Auroroa when I asked if the drivers above were the best to use on the Nexus :( 

You have the correct X driver and kernel driver.   That should give you some limited blit acceleration on on the Nexus One for 2D rendering.
Unfortunately, the parts you really need are the proprietary 3D drivers, and those are not available anywhere.  Without those, you'll be stuck
with software 3D for the long haul.  Sorry.
