Pandaboard SGX drivers for Linaro 12.07 Android ICS release (3.4 kernel)

[shan_au]

Hi,
I am new to this Android porting activity.
Linaro Android ICS release 12.07 doesn't have Pandaboard SGX540 drivers. Any idea why this has been dropped from the 3.4 kernel based 12.07 ICS release. Same is present in 3.2 kernel based ICS release.

My current Android Linaro kernel 3.4 doesn't have SGX drivers. Please let me know the feasibility of migrating 3.2 kernel ICS graphics(SGX) drivers to 3.4 kernel and making ICS & graphics up on Pandaboard.

Here is the Linaro release notes... which talks about missing drivers. (section:3.1.1)
https://wiki.linaro.org/Cycles/1207/Release#Android

Please guide me method to migrate the drivers!

Thanks,
Shanmugam T

There is no drivers for Android JB... yet. But there are some people
that works on it, so soon (in few weeks, probably) you - and the
community as well - could get these drivers.

Hi Pervushin,
Thank you for the information, is it same case for Android ICS (3.4 kernel) also ?

I am planning to migrate the SGX drivers from 3.2 kernel ICS  to 3.4 kernel ICS. Could you please comment on this, feasibility & complexity!

Thanks,
Shanmugam T

Shanmugam,

Feel free to take a look through:

https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AkxwyUNxNaAadGVWd3pZazdaRUU0MnRnWmgwbVhTR0E#gid=17

Its a sheet with the test results of all the panda builds we've done.

Our last ICS build with SGX graphics enablement for ICS looks like:
