https://bugzilla.suse.com/show_bug.cgi?id=1201963 Bug ID: 1201963 Summary: 11th Gen Intel(R) Core(TM) i5-1145G7 throttling to 400MHz from 70�C until it reaches 54�C Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: gryffus@hkfree.org QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 860458 --> https://bugzilla.suse.com/attachment.cgi?id=860458&action=edit Turbostat log output I have a Dell Latitude 5420 laptop and i am experiencing CPU slowdown when using any graphical / CPU demanding application. The laptop contains 11th Gen Intel(R) Core(TM) i5-1145G7 which can do 4,4GHz on turbo. When the system reaches about 70�C, all cores switch to 400MHz and stay there until temperature hits 53-54�C. I can see this behavior especially in Vulkan graphics applications, but not only in them, it just happens almost instantly there, since the 70�C is reached within about 30 seconds there. I would want to raise the temperature limits to at least 80-90�C or disable throttling completely (at my own responsibility of cooking it). But throttling from 70�C seems as a complete nonsense to me - the CPU package gets to this temperature in 10-20 seconds under load, so i basically never make use of the 4,4GHz. What i have tried: 1) Kernel 5.19 from Kernel:HEAD - no change 2) installed throttled ( https://github.com/erpalma/throttled ) - no change 3) blacklisted intel_powerclamp, intel_rapl_msr, processor_thermal_rapl, intel_rapl_common kernel modules - no change 4) cpupower frequency-set -g performance - no change # cat /sys/devices/platform/*/uuids/current_uuid INVALID # cat /sys/devices/platform/*/uuids/available_uuids UNKNOWN # cpupower frequency-info analyzing CPU 0: driver: intel_pstate CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 4.40 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 4.40 GHz.
