Phoronix: RadeonSI Driver Sees GPU Hang Fixes - RDNA4 Fixes, Optimally Programming "OREO MODE"

A number of GPU hang fixes have been merged for AMD's RadeonSI Gallium3D driver within Mesa. These fixes should help further enhance the current RDNA3 GPU driver support and also has fixes for stabilizing the upcoming RDNA4 GPU support...

So we need to figure out what Oreo mode means? Wtf?

[brent]

OREO mode sounds like some kind of inside joke among the HW engineers.

[duby229]

It has something to do with improving Ray tracing performance. It's something about a dual source import, whatever that means

EDIT: All I could find was forum conversations speculating about it. I didn't find anything official. Sorry no links.

EDIT: Apparently it's something they picked up from DX11...

ORder External/Exported Objects is my guess

ORder External/Exported Objects is my guess

Definitely a better guess than mine would have been.

Everything in the committed code is around the order of exported objects. When you see the words "order", "export", and "object" it isn't hard to make an OREO.

The one that makes me giggle is the OMODE

I see a lot of the word blend in there too.

So at this point I think OREO mode imports 2 source inputs and then blends them in some optimized way and then exports it as a single output?

Whatever OREO means, the question is: Will it help AMD to increase their market share for dGPUs? It decreased to only 12%, while team green is at 88%. AMD seems to put the prices of their GPUs just a little bit below Nvidia's, thinking this would benefit them. But they evidently lost market share and in the long run that tactics may hurt them even more.

AMD's move with Strix may work out to take away some butter and bred from Nvidia in the entry level dGPU section. But they definitely also need a competitive and attractive mid-tier GPU line-up, to gain real traction. The high performance GPUs are the ones, which cause the hype. And If you don't have those or a top high end model, you need to attract the masses with high performance and efficiency at way lower prices.

Do those numbers account for the fact that countless AI startups are buying up 4090s in bulk? I suspect the market penetration of AMD among actual gamers is somewhat higher then 12%.
