amdgpu_bo.c in libdrm uses reference counting to track usage of each amdgpu_bo. amdgpu_bo_import increases reference count and amdgpu_bo_free decreases it.

in mesa, each time when amdgpu_bo_from_handle is called, it calls amdgpu_bo_import to get amdgpu_bo and build amdgpu_winsys_bo. Because amdgpu_winsys_bo is also reference counted, amdgpu_bo_free will be called only once for each amdgpu_winsys_bo.

so, for one amdgpu_bo, if amdgpu_bo_from_handle is called for more than once, amdgpu_bo_import and amdgpu_bo_free calls will be unbalanced.

Tested on Mesa 18.2.0 + GBM gralloc, Android 7.1.2-r36, AMD Radeon RX560

I asked Chih-Wei Huang:

since Mesa supports full OpenGL contexts in addition to OpenGL ES contexts created via EGL API selection can you support also full OpenGL contexts on Android similar to NVidia Shield Tablet supports..
i.e. support OpenGL in EGL_RENDERABLE_TYPE
see for example Shield Tablet gfxbench report:
https://gfxbench.com/resultdetails.jsp?resultid=hSmWKjDNbkDzGAPsqQ5d8Q
It says:
EGL_RENDERABLE_TYPE: OpenGL_ES
OpenGL_ES_2
OpenGL
(77)

He answered: "I have no idea about that topic. "

Perhaps currently Android-x86 5.1.1 supports but in case not, you seem the correct guy to ask
to patch Mesa Android support for enabling full OpenGL contexts in Android..
also related to full OpenGL context support, eventually LLVM version will be important for radeonsi support.. for example supporing tesselation shaders and perhaps fp64 support extensions require new LLVM 3.7.0.. with it we get GL4.1 support with LLVM 3.6.x we get only OpenGL 3.3 support..

so if not difficult can you be fast upgrading LLVM version for Mesa Android if/once full OpenGL context support lands..

what are your thoughts?

Hi,
just thinking about getting Skylake PC.. will GPU be supported? seems needs new kernel 4.2 or 4.3 can you provide some build with latest kernel and Mesa posible for testing with new PCs?

Hello, I think theres a problem with 17.3.1_oreo-x86, Im experiencing issues with video apps like youtube, it will only play audio and shows a blank video screen but audio plays fine, I have tryed loading a MP4 enoded to x264 from https://peach.blender.org/download (Open movie project) however mpv just crashes out.

So could this be a problem with 17.3.1 for Intel 965GM, Also with this 17.3.1 my screen resolution has changed what has inproved but no video playback.
