[Kernel-packages] [Bug 1838141] Re: intel_pstate not working. CPU frequency fixed at 800MHz. No cpu frequency scaling.
Personally I've disabled pstate driver from kernel command line. Events like suspend, lid close and restart completely changes the behavior. While working on battery I sometimes will close the lid and when I open back CPU is at 4Ghz and battery gets drained in 30mins. Not to mention the heating. *It simply doesn't work.* The acpi driver is much better and battery life is great too. No lid/suspend issue so far.

Thinkpad T460 with Intel(R) Core(TM) i7-6600U CPU @ 2.60GHz Recently went Ubuntu 16.04 -> 18.04. Using intel_pstate in default configuration.

It lives most of it's life in "clamshell" mode and is only occasionally actually opened. CPU gets "stuck" at 1.6GHz after clamshell->clamshell suspend/resume cycle. Opening the lid (!!) resolves the issue. Doesn't come back when I close it again. :wtf: I am at a loss for words. Definitely did not have this issue in 16.04.

[Kernel-packages] [Bug 1838141] Re: intel_pstate not working. CPU frequency fixed at 800MHz. No cpu frequency scaling.
I had the same Problem with the CPU in my Lenovo T470s. Intel(R) Core(TM) i5-6300U CPU @ 2.40GHz i tried intel_pstate=disable which did fix the stuck @ 800 MHz Problem. But Managing CPU govenors ans frequencies was still kind of broken with Kernel 5.3.0-40. So I deleted the intel_pstate kernel Parameter and checked the BIOS / EFI for the CPU management settings. After I disabled Intel Speed Stepping in the Bios, everything was working as expected in Linux. intel_pstate is still availible for the Kernel and the Management of Govenors and Frequencies is just working fine. After a bit of reading up un intel_pstate i think I found another possible Solution or the core reason for This Problem. I did not try it since my problem was solved via the Bios Setting, but it reads promissing: https://www.kernel.org/doc/html/v5.3/admin-guide/pm/intel_pstate.html --- snip If the processor supports the HWP feature, it will be enabled during the processor initialization and cannot be disabled after that. It is possible to avoid enabling it by passing the intel_pstate=no_hwp argument to the kernel in the command line. If the HWP feature has been enabled, intel_pstate relies on the processor to select P-states by itself, but still it can give hints to the processor's internal P-state selection logic. What those hints are depends on which P-state selection algorithm has been applied to the given policy (or to the CPU it corresponds to). ---snap -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1838141 Title: intel_pstate not working.

Hello there, I'd like to just note, that I had the same problem with 18.04 LTS HWE (5.0.0-23-generic) and an i5-8350U, but mine was clocking around 3.6GHz on each core. Upgrade to 5.0.0-31-generic has resolved this issue with intel_pstate driver, but using the kernel parameter intel_pstate=disable was a usable workaround as well.

@kaihengfeng I'll test and post the results soon. @anthonywong If I disable pstate with "intel_pstate=disable", frequency goes up to 1000Mhz max, also laptop runs very hot and battery lasts 30-60mins without pstate. On Windows 10 CPU goes all the way to 4.1GHz so it's not a hardware issue. Linux kernel 4.17.3, 4.17.2, 4.17.1 are also working as expected (4.1GHz) without overheating and >3hrs battery.
