Equinix is shutting down its operations with us on April 30, 2025. They have graciously supported us for almost 5 years, but all good things come to an end. We are expecting to transition to new infrastructure between late March and mid-April. We do not yet have a firm timeline for this, but it will involve (probably multiple) periods of downtime as we move our services whilst also changing them to be faster and more responsive. Any updates will be posted in freedesktop/freedesktop#2011 as it becomes clear, and any downtime will be announced with further broadcast messages.
Project 'drm/intel' was moved to 'drm/i915/kernel'. Please update any links and bookmarks that may still have the old path.
@cooperch
Allow me to correct one thing in here, not yet got CML-R CPU from Intel, now ODM test sample is CML ES CPU on RKL-S ES/Pre-QS PCH.
Answer your questions:
yes, WinOS display works with CML CPU + RKL PCH-H (desktop)
BIOS is WW44 BKC
@kaichuan.hsieh can you help on this? -> Could drm-top be reproduced this issue?
@Fanny.C I've checked drm-tip, its code logic is the same, and I tried to omit the pch check in intel_pch.c in drm-tip, the device hang while loading initramfs.
@kaichuan.hsieh Can you help change title? I can't modify it. BTW, have you check this issue on Ubuntu 20.10?
@cooperch This issue is blocking 4 platform CML-R + RKL PCH testing now, can Intel help analyze issue on Intel RVP? We will check latest BKC in parallel.

@cooperch May i know any good news from backend team...?
(12/2) update isolation status...
Install pure Ubuntu 20.10 (kernel 5.8) -> no display issue.
if select "try Ubuntu without installing (safe graphics)" => display works. (should be similar added nomodeset commend?)
Tried Intel latest CML GOP driver v1109, no display.
It will always WARN_ON, when the pch detects that the CPU is not ROCKETLAKE or TIGERLAKE, this part is the same in drm-tip and mainline kernel. Do you think it will have different result on RVP?
The RKL RVP we have is RKL-S 8+1/TGL PCH, mm# 99A6Z6, so we need Intel to confirm if the CML CPU provided by ODM, NA QTB1 2.5GHZ V934D370 (e4) is suitable for installation on it.
