Re: [Bf-committers] I can't use Opensubdiv on 2.79 RC1 with an AMD RX 480 (Linux)

[Sergey Sharybin]

Brecht, AMDGPU is an opensource driver implementation from AMD. It is NOT
directly used by system and/or applications, instead it is hooked up to
Mesa via LLVMPipe. So as far as applications are concerned, their OpenGL
provider is Mesa.

The issue here is that driver developers doesn't seem to be into
implementing all OpenGL features within compatibility profile. Core profile
on AMDGPU goes up to 4.5 if i'm remembering things correctly.

Re: [Bf-committers] I can't use Opensubdiv on 2.79 RC1 with an AMD RX 480 (Linux)

[Brecht Van Lommel]

I think in this specific case the driver is not installed or configured
correctly. The system info shows it's not using the AMDGPU driver for
OpenGL, but Mesa. The RX 480 is certainly new enough to support OpenSubdiv.

Re: [Bf-committers] I can't use Opensubdiv on 2.79 RC1 with an AMD RX 480 (Linux)

[Sergey Sharybin]

Blender requires decent OpenGL for drawing OpenSubdiv meshes. This is the
only way to get decent speedups.

But it's not all that sad as it sounds! In Blender 2.8 we've switched to
OpenGL core profile, which has higher OpenGL support than the compatibility
profile we use in 2.78/2.79. Unfortunately, we did not hook up OpenSubdiv
in 2.8 branch yet.

So with 2.8 OpenSubdiv support will come to more hardware (including Apple
macOS) with more features (like adaptive subdivisions).

[Jefferson Rausseo]

Is it possible to use Opensubdiv with CPU only? For example with OpenMP.

Re: [Bf-committers] I can't use Opensubdiv on 2.79 RC1 with an AMD RX 480 (Linux)

[Sergey Sharybin]

Thanks for the file. This clarifies a lots.

Your driver only provides OpenGL 3.0, for which we need the following
extensions:

- uniform_buffer_object
- geometry_shader4
- texture_buffer_object

The latter two are not supported by the driver you're using (you can see
that in the `extensions` section of the system-info).
