Intel Arc A770 - failed experiment

[Hasturtium]

It's been 2 years and ... unfortunately the driver still does not support non-x86.

i915's never getting rearchitected for non-x86, but aarch64 reportedly runs Arc with a few caveats using Intel's xe driver. There's nothing it offers that my W6600 doesn't do well enough for my needs at this point, but I'd like to think it'll work since Power9/Raptor's PCIe implementation's apparently less warty.

Quick question/update: I've come into a dinky but adequate Arc A380 and am wondering what the odds are that I could use it in my Blackbird, freeing up the W6600 I've had in there for a different purpose. Anyone hear reports of the i915 or xe driver actually working on ppc64le before I free up an afternoon to try?

I don't think anyone has tested it yet, did you end up doing so?

I am rolling my machine over to Fedora within the next couple of weeks. I’ll boot it with the Arc A380 I have kicking around and see if I can coax it into working.

Booted into a fresh install of Fedora 43 after patching, and it is not currently supported there via xe or i915 as far as I can tell. lspci enumerated it correctly and ID'd it as Intel DG2 [Arc A380], but there was no acceleration, no identification of its audio, and several libraries I'd expect Fedora to host for Intel GPUs aren't for ppc64le. So I'd guess even the xe driver has not yet reached mature status on ppc64le. Looks like my Radeon W6600 will continue to perform... not that I've pushed it terribly hard in that machine outside of running 30 year old open source games at 4K with antialiasing, or the odd bout of Quake II RTX.
