Hi Daniel
     It works on open-source with following stack:
         ion -> dma_fd  -> prime fd to handle -> drm -> vop

     ion is the android ION memory allocator, its driver at 
upstream-kernel/drivers/staging/android/ion.

     We have some application use ion on android, and want to port to 
Xorg side.

Thanks

Hi Daniel
     It works on open-source with following stack:
         ion -> dma_fd  -> prime fd to handle -> drm -> vop

     ion is the android ION memory allocator, its driver at 
upstream-kernel/drivers/staging/android/ion.

     We have some application use ion on android, and want to port to 
Xorg side.

Hi Daniel
     It works on open-source with following stack:
         ion -> dma_fd  -> prime fd to handle -> drm -> vop

     ion is the android ION memory allocator, its driver at 
upstream-kernel/drivers/staging/android/ion.

     We have some application use ion on android, and want to port to 
Xorg side.
