Does Mali T760 support UMP?

Hi mop, Chris,

Headers are there indeed, however functions are not included in libmali binary so you will get stuck with linking errors . I got stuck and then checked using objdump -T.

Related to this I have a more specific but similar question (or do I need to start a new discussion?):

I got the hardware video decoder working on my firefly/rk3288. I can blit the yuv/nv21 output frame to rgb frame memory using fireflys dedicated 2d acceleration hardware. All I need right now is a memory pointer, pointing directly to the texture memory, in order to use the video frame in my shaders. In android I would create a GraphicBuffer object and this to eglCreateImageKHR()+glEGLImageTargetTexture2DOES. Right now I use glTexSubImage2D to copy and I get about 12 fps for 1920x1080 frames.

What is the best way to do this for firefly linux 3.10 with fbdev mali t760 driver? How can I get a pointer sharing CPU/GPU texture memory? UMP isnt there it seems. And is there maybe some sample code available?

EDIT: I just started another discussion/thread for this, not to interfere with this one: How to share texture memory between CPU/GPU for firefly's/rk3288 fbdev Mali-T764

Hi mac_l1,

Which functions are missing? GL functions or UMP ones? From memory UMP userspace functions are in a libump.so userspace library not libmali.so

Hth,

Chris

Hi Chris,

I guess that is true, also my first thought.

However, I can't find libump.so for T760 anywhere.

Is it available somewhere? Or is it expected?
