When turbo mode is unavailable on a Skylake-X system, executing the command: "echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo" results in an unchecked MSR access error: WRMSR to 0x199 (attempted to write 0x0000000100001300).
This issue was reproduced on an OEM (Original Equipment Manufacturer) system and is not a common problem across all Skylake-X systems.
This error occurs because the MSR 0x199 Turbo Engage Bit (bit 32) is set when turbo mode is disabled. The issue arises when intel_pstate fails to detect that turbo mode is disabled. Here intel_pstate relies on MSR_IA32_MISC_ENABLE bit 38 to determine the status of turbo mode. However, on this system, bit 38 is not set even when turbo mode is disabled.
According to the Intel Software Developer's Manual (SDM), the BIOS sets this bit during platform initialization to enable or disable opportunistic processor performance operations. Logically, this bit should be set in such cases. However, the SDM also specifies that "OS and applications must use CPUID leaf 06H to detect processors with opportunistic processor performance operations enabled."
Therefore, in addition to checking MSR_IA32_MISC_ENABLE bit 38, verify that CPUID.06H:EAX[1] is 0 to accurately determine if turbo mode is disabled.

FYI, this seems to have broken turbo boost on some Clevo systems with an Intel Core i9-14900HX CPU. These CPUs obviously support turbo boost, and kernels without this commit have turbo boost working properly, but after this commit turbo boost is stuck disabled and cannot be enabled by writing to /sys/devices/system/cpu/intel_pstate/no_turbo. I made a bug report about this against Ubuntu's kernel at [1], which is the only report I know that is able to point to this commit as having broken things. However, it looks like an Arch Linux user [2] and a Gentoo user [3] are running into the same thing.

As the bug report suggested, the system boots with no turbo, it must be forcefully turned ON by writing to this attribute. I wonder if there is a BIOS option to turn ON turbo on this system?
This processor itself is capable of up to 5.8 GHz turbo.
I will try to find contact at Clevo.
We can try to reduce scope of this change to non HWP only where there is unchecked MSR issue.

I just double-checked the BIOS settings, there does not appear to be any setting related to turbo boost there. The closest there is, is overclocking settings, which comes with warnings about possibly causing the system to become unbootable, thus I think those settings are for true overclocking and not turbo boost.
This processor itself is capable of up to 5.8 GHz turbo.
I will try to find contact at Clevo.

That sounds like a good idea to me.

I can confirm that this patch does resolve the issue when applied to Kubuntu Focus's 6.14 kernel. CPU frequencies are available that require turbo boost, and `cat /sys/devices/system/cpu/intel_pstate` returns `0`. The logs from `dmesg` also indicate that turbo was disabled earlier in boot, but the warnings about turbo being disabled stop appearing later on, even when manipulating the `no_turbo` file:

I can confirm that this patch does resolve the issue when applied to Kubuntu Focus's 6.14 kernel. CPU frequencies are available that require turbo boost, and `cat /sys/devices/system/cpu/intel_pstate` returns `0`. The logs from `dmesg` also indicate that turbo was disabled earlier in boot, but the warnings about turbo being disabled stop appearing later on, even when manipulating the `no_turbo` file:

Hi Srinivas,
I have tested the newest patch against KFocus's 6.14 kernel on the affected hardware, and can confirm that this patch also allows Turbo Boost to function correctly. High-frequency modes are available in cpupower-gui, and the "Turbo disabled by BIOS or unavailable on processor" messages stop occurring in dmesg shortly after boot.
