Offering Panther Lake (Xe3 / Arc B390) hardware for testing and development #11

Hi, I've been following XeGfx for a little while now, and I was wondering if you'd be interested in having me help test and develop macOS support for my Framework Laptop 13 Pro (Intel Core Ultra X7 358H, Arc B390 Xe3 iGPU). I'm fairly new to driver development, so I might need some guidance with the more complicated parts, but I'm willing to put in the time to do so. I'm currently running EndeavourOS with the Linux xe driver, and I'd be happy to provide any logs, tests, or whatever and try to troubleshoot.

Let me know if my hardware would be useful to the project.

Hi lemlnn, yes, this would help, thank you.

One thing first so expectations are right: XeGfx today is built on i915, which stops at Meteor Lake and Arrow Lake. The Arc B390 is Xe3, and on Linux only Intel's newer xe driver handles it. Getting there is tracked in #8 and hasn't started yet, so your machine won't run XeGfx in the short term.

What helps now, from your EndeavourOS install:

lspci -nnk -s 00:02.0
sudo dmesg | grep -iE 'xe |guc|huc|gsc|dmc' (device ID, GMD_ID and the firmware versions the xe driver loads)
sudo cat /sys/kernel/debug/dri/0/info if debugfs is mounted

Also: does macOS boot on that Framework at all yet (OpenCore, any version)? If it does, the read-only probe in CONTRIBUTING.md (stage 2) is the next step, and that is safe to run.

Anything you send, whether it works, half works or fails, goes into the README's credits with your handle.

I'm pretty sure Framework ships with InsydeH2O UEFI firmware by default so I still gotta attempt Opencore in a bit, and also here's my system info if you need it
