I just want to know the workloads that are important to you, to make
sure they are included in my benchmarking.

There are a couple of kernel features in the pipeline to speed up some
frequent paths, and I plan to do an attack of the gen4+ shaders. Besides
a few anomalies in x11perf, the ratelimiting step at the moment is the
Render protocol which doesn't provide complete or optimal offload of
even the <canvas> spec. And of course, there is plenty within the Render
spec that is left to optimise if it finds a use in the wild.
As for the tearing issue, there is no nice solution this side of
Wayland. The recent hardware has been designed around a compositor, and
it is likely that more and more features of the display engine will
require compositing. It appears that TearFree is unavoidable and so will
need lots of love and further development.
