MSM/QSD hardware adaptation

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.

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.

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
