For your accelerated impl., you need to provide libhgl.so so that libEGL.so will be able to use it. It is expected that libhgl.so implements and exports both eglXXX and glXXX symbols.
And you need to make sure that what android passes to you is something that your hw can accelerate. E.g., surfaces based on special type memory, etc. > - Is there any help available for porting of OPenGL ES on HW accelerators? > or please give me some guidance how to proceed with porting on HW > accelerators? I have done some work to utilize intel 3d chipsets for acceleration. You may want to have a look at this thread http://groups.google.com/group/android-porting/browse_thread/thread/9252d8b7e95898c You can see what parts of android need to be changed for acceleration, and does something that fits your hw. -- Regards, olv --~--~---------~--~----~------------~-------~--~----~ unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting -~----------~----~----~----~------~----~------~--~---
