T14s Gen 2 (Intel) S0ix support in Linux?

2021-07-29, 12:56 PM

Anyone here running Linux on this machine and know how well recent Linux kernels will support s0ix states on it (aka Modern Standby)?

We've ordered one for a new colleague at work, and I'll be tasked with setting it up, and it would be good to know what to expect given that the option of enabling S3 in BIOS will not be available.

I'll not be against having to install a newer kernel and Intel graphics driver, but if anyone has some experience I'm idle ears.

Lenovo: Have you tested that s0 sleep works well on this laptop? Have you or will you contribute patches to make it work well?

I should clarify: It is the T14s Gen 2 we've ordered, not the T14 Gen 2.

Hello estan!


Greetings

 


The S3 sleep is not supported under the Tigerlake platform. No information yet if there are plans of adding it.

You can provide your comments or suggestions on the feedback hub on the support page to reach the right folks from Lenovo.

 

Regards

Hi,

 

I've moved your posts to a Linux forum.

 

Your subject and post don't quite match IMHO.  I wonder if changing the subject to something like "T14s Gen2 S0ix support in Linux?" - or adding that to the subject - would attract more eyeballs?

 

regards,

Z.

Thanks. I know that S3 is not supported currently on Tiger Lake platforms. I was asking about the status of support for S0ix under Linux. Can you ask the engineers about how well S0ix will work on current Linux kernel with the T14s Gen 2 (Intel)?

 

(Thanks for moving my post. I thought it was sort of on topic since the original post was about the lack of S3 BIOS option on a very similar model (T14 Gen 2), and that option, on models where it exists, was added specifically for Linux users. But you're right, probably better as its own topic.)

T14s Gen 2 (Intel) S0ix support in Linux?

2021-08-06, 9:29 AM
I guess what I'm asking is: Has anyone been through the steps at https://01.org/blogs/qwang59/2020/linux-s0ix-troubleshooting and can confirm that this laptop reaches a high level of s0ix residency properly, and comes out of it OK? And for Lenovo: Can your engineers confirm that s0ix should work OK on this laptop, given recent enough firmware/kernel/drivers?

T14 Gen2 does not, at least on 5.10.XX LTS. Given that it goes into hard reboot after resuming from S3, S0ix is the lesser of two evils.

Hi,

 

We certify the platform with S0ix (and for the Tigerlake CPUs it's what Intel recommend). S0ix is supported and if you see problems let us know. The T14G2 hasn't completed cert because of the networking issue - but there aren't any suspend related problems that I know of

Sure, what output you're after? Running T14 Gen2 Intel, 1145g7 CPU. Debian, v5.10.46 (currently frozen, will update to latest LTS once the Bullseye is out).
