Ok,
I compiled today the driver and run and up to date clinfo tool (full report below):

extensions differences vs Windows driver are:
Linux drv has (and Windows no):
cl_khr_priority_hints cl_khr_throttle_hints cl_khr_create_command_queue

more info on "cl_khr_create_command_queue" extension, please? can't find info on OpenCL registry..

Win drv has (and Linux drv no):
cl_khr_gl_sharing cl_khr_gl_depth_images cl_khr_gl_event cl_khr_gl_msaa_sharing

as you mention on README "delta" other driver:
OpenGL sharing with MESA driver..

this means currently there is no OpenGL interop on Neo with Mesa right?
are you working on it/have plans to implement it?

thanks..

On extensions in Linux, not present in Windows:
NEO supports Windows and Linux using the same code base, but there is some latency in delivering the Windows closed source driver (integration, validation, signing) compared to Linux, where the source code is provided continously. These extensions will be present in the Windows shortly. New features on Windows will be present in subsequent driver releases.

On cl_khr_create_command_queue:
Posting of the spec for this extension is WIP in Khronos.

On gl-sharing:
The NEO driver on Windows provides sharing with the closed source OGL driver developed by VPG. On Linux, we intend to add sharing with MESA, but do not have any firm timelines as of today.
