There is one more thing that may be relevant for you. The old r3p0 version of the mali blob can't fully utilize both pixel processors of the Mali400 MP2. So the performance is not optimal on Allwinner A20. It is possible to upgrade to a newer version r3p2-01rel2 of the blob to get better performance, but I was not very sure about it without a good justification (like somebody having a real use for OpenGL ES and able/willing to report bugs): http://thread.gmane.org/gmane.comp.hardware.netbook.arm.sunxi/4676 Also blobs are a temporary placeholder solution until we get free open source drivers. Investing extra efforts into getting blobs running may be counter productive at this moment.
I tried to use it once, but i got an unresolved symbol. I think is the one you mentioned there: https://groups.google.com/forum/#!msg/linux-sunxi/zx4gwC1QyMc/h_mFGeL6nzMJ
is that preload hack still necessary?
