Phoronix: RadeonSI Enables Compute PBO Blits: "Massively Improves Perf In A Number Of Cases"

Related to the work by Mike Blumenkrantz for significantly improving the Mesa glReadPixels performance by more than 100%, the open-source driver developer at Valve has now enabled compute PBO blits within mainline Mesa for the AMD Radeon "RadeonSI" Gallium3D driver...

The Zink supporters are going to feel this in the morning.

This and previous PR apply cleanly on top of 24.1.2

Was this already enabled for Intel in the original PR?

Many use Ubuntu (LTS) or other slow moving distro where the changes will be included in a year or two.

I'm still sporting Kubuntu 20.04 LTS and currently have Mesa automatically upgraded to version 24.1.2. All I had to do was install the Mesa PPA - https://launchpad.net/~kisak/+archive/ubuntu/kisak-mesa some years back ... and presumably it also requires Hardware Enablement (HWE) as well. I turned that on a long time ago.

Mesa updates are in the HWE releases anyway, I think? I use the kisak PPA too, but I think Mesa updates flow every six months from the .2 release onwards; 24.04 gets mesa from 24.10, and then from 25.04 etc. until the next LTS release.

20.04? Isn't that still on Gnome 3.3x? You should try 24.04, it's pretty sick

Somehow I think a KDE user doesn't care about Gnome.
