i7-1355U support (Thinkpad T14s Gen4)

[carlosabalde]

Is it possible to add support for the following CPU model (Thinkpad T14s Gen4)?

model name      : 13th Gen Intel(R) Core(TM) i7-1355U
cpu family      : 6
model           : 186
stepping        : 3

In the meantime, testing this...

There are >1 people curious about this specific CPU :) Do you have any results from your test?

[motiejus]

I did a test myself. With this package the upper frequency went up from 1.8GHz to 2.2GHz. A welcome improvement, but still has ways to go.

Unfortunately, that didn't work. It went down to 1.7GHz after a couple of days of uptime and stayed at that.

I didn't spent much time on this, but for me is working as expected combined with tuning of the platform profile (i.e. /sys/firmware/acpi/platform_profile) and the CPU scaling governor (i.e. /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor). Sharing just in case it helps.

[motiejus]

@carlosabalde those didn't help (both were set to "performance").

HOWEVER removing tlp fixed the cpufreq issues on my machine! I had tlp enabled for all my laptops since forever for battery management ("stop charging at 80%"), not any more!

[carlosabalde]

Strange. I'm using tlp too to keep battery between 60-70% 🤷

Hello folks, I have this CPU and the #346 (comment) made throttled happy to load and work with it. The system seems to perform well.
