Probably the termald sorts out the throttling and other issues. I would say we should enable this service by default on new cpus and probably install it in laptop pattern.

We can add supplements to thermald specifying the CPU IDs that require thermald, too, instead. Adding thermald maintainters to Cc.

BTW, does this happen also with SLE12-SP2 kernel?

Yes for the old kernel; I tried leap first... :) Technically if we have way how to identify CPU then I am fine for it being supplements. But we also need to change default presets for systemd to enable thermald by default if installed. -- You are receiving this mail because: You are on the CC list for the bug.

Oh, then it's a problem since I'm not sure whether thermald is included in SLE[SD]12-SP2. Thomas?

It is not present on the SLES12 atm, only Leap and TW.

That's true. Let's leave the decision to thermald maintainers.

@thermlad-maints: so what is your take, would you guys add those supplements? -- You are receiving this mail because: You are on the CC list for the bug.

I vaguely remember some report(s) about thermald actually causing the device to overheat and do a hard shutdown. That's not too unlikely, considering its main purpose is to avoid throttling the CPU harder than necessary when the thermal limit is approached/reached.

The thermal limit shouldn't be reached under normal circumstances (like "browsing+ssh" in the original comment), and so thermald shouldn't be absolutely necessary with a properly designed cooling solution. Unfortunately many laptops do not have one, so thermald has a noticable impact on performance on those. However, that comes at a cost: The device will run hotter.

Yes. It's good to give users a choice :)

Any opinions about this?

Supplements: (modalias(cpu:type%3Ax86*ven0000*) if kernel)

I guess this would work as a first shot, that's similar to ucode-intel.

While there are more specific modaliases which could be used here (like some intel specific ACPI platform devices), those may change in the future and then the supplements would silently not work anymore.

Agreed.

Ideally it only matches physical hardware, but I don't think we have any capability for that (yet).

And, thermald won't be enabled / activated by the package installation alone, right? -- You are receiving this mail because: You are on the CC list for the bug.

Sorry to highjack this one with another issue: I have this bug lingering around for quite some time.

ucode-amd is recommended on Intel CPU systems https://bugzilla.suse.com/show_bug.cgi?id=1158704

From Kernel:HEAD kernel-firmware: %package -n ucode-amd ... # new style (after 3.12 kernel somewhen) Supplements: modalias(cpu:type%%3Ax86*ven0002*) # old style (before 3.16 kernel) Supplements: modalias(x86cpu:vendor%%3A0002%%3Afamily%%3A*%%3Amodel%%3A*%%3Afeature%%3A*)

any ideas or seeing something obvious ;)

The Supplements is fine, but it's pulled just because of Recommends in the patterns-base-enhanced_base (as already suggested in bug 1158704). You may reassign the bug to Component patterns if it's really superfluous. -- You are receiving this mail because: You are on the CC list for the bug.
