Could you kindly give some help:
1. If Mesa provide API to create GL sharder storage buffer from dma_buf file
descriptor?
2. If EGL can covert EGL texture object to shader storage buffer object?
Thanks,
Zong Wei

code snippet
https://github.com/intel/libxcam/blob/master/modules/gles/gl_buffer.cpp#L94
https://github.com/intel/libxcam/blob/master/modules/gles/gl_buffer.cpp#L127
I wonder If there has other efficient way to sharing data between CPU & GPU
GLES shader?
Thanks,
necessary for
such operation?
The hardware I’m using is Broxton, and graphic driver is Mesa 18.1.0-devel.
Thanks,

Marek & Palli, I parsed the returned GL extensions string, it sure contains "
GL_OES_EGL_image_external ". I made a mistake by looking up log manually
before, the string must be truncated by log length limitation.
Thank you very much!

to query the
