Phoronix: Panfrost Making Use Of The Gallium3D I/O Vectorization For Better Performance

At the end of May I wrote about Intel's Iris Gallium3D driver achieving performance optimizations with new NIR I/O vectorization functionality. The open-source Arm Mali "Panfrost" Gallium3D driver has now wired into this code too for better performance...

Is this driver now wired up for some weekly perf tests Michael ? If not it might be work it

Is this something for radeon's nir backend too?

Nice, I wonder when NIR becomes the default in radeonsi too... it is in the pipeline since a very long time.

No. LLVM already takes care of the vectorization, and does so later on in the process which is better to allow LLVM optimizations to run first.

There's been quite a bit of work on it over the last few months. I don't know when they're planning to switch over, but I bet it's by the end of the year at least. My guess is 19.3.

Is there some recommended SBC when one wishes to try this Panfrost driver?

Thanks, I have NIR in my /etc/environement and I couldn't find any game that has some issues because of this.
