Intel Arc A770 - failed experiment

--- Quote from: Hasturtium on November 03, 2022, 10:04:54 am ---- ReBAR's reportedly a PCIe 3.0 feature, so I'm a little surprised Blackbird and Talos don't support it. The feature is important for maximizing hardware performance on Arc / Alchemist, but I don't know how drastic a difference it would make for the less game-centric 3D use cases of a typical Power9 build.

I was wrong. @q66 has confirmed ReBAR is supported. Now it is all about waiting for Intel team to refactor the driver to be independent of X86 platform.

It's good to see 3 companies NVIDIA, AMD and Intel have released GPU that supports AV1 decoding/encoding. Soon I believe Apple will incorporate that function into the next A16 or M3 SoC.

There's seems progress upstream in removing x86 dependency codes

Let's hope by the end of next year we would have a fully decoupled i915 driver

MauryG5:
Yes, I also read the news that they are working to make the new Arc GPUs usable also by other alternative architectures to X86. We hope that they will be well supported and that a user like us at Power can choose which GPU to buy, without being forced by the support issue... Let's see what happens in the coming months... Meanwhile, the Radeon 7000 series are about to arrive...

tle:
@q66 has been attempting to get the i915 compiled. Though he did not have success (yet)

Hasturtium:
It looks like post-Skylake GPUs will be supported in a new Xe/Arc driver in Linux going forward. At least some of that is likely tied to removing x86isms that would keep Intel out of datacenters running ARM64, Power, and RISC-V servers in the datacenters Intel is eager to grow into. So let's hope for good things!
