Hi,

Your GL setup seems broken ...

Post the output of glxinfo and clinfo


>> libEGL warning: DRI2: failed to find _glapi_get_proc_address

Again, something seems broken in your OpenGL setup


>> [+] Selected device: Devastator

So you GL/CL drivers reported that they could share info and it
allowed fosphor to create a context for it, then when asked to
actually share info, it refuses wit CL_INVALID_CONTEXT ...

Look in lib/fosphor/cl.c in the cl_do_init function at the very
beginning of the function and comment out : " self->flags |=
FLG_FOSPHOR_USE_CLGL_SHARING; "

This will prevent it to try and share data between CL and GL ...
