Developing only at the tip is a phenomenon unique to open-source development. Commercial software is developed against the target that customers will actually be running at the time the software needs to ship.

I’m glad to see these drm-intel-backports trees. Let’s hope that in the future they are supported at least as well as the compat-wireless trees. We shouldn’t need a bleeding edge kernel to support a new device.

Some work is being done to bring OpenCL to Gallium3D.

But you wrote : “there are no plans to provide opencl support in the open-source drivers at the moment”

Therefore it seems that not always everyone wins :-/
