From: Mario Limonciello <mario.limonciello@amd.com> stable inclusion from stable-v6.6.41 commit 2ca2fd474d862c9b144ea4ed100ee4591f52d574 bugzilla: https://gitee.com/openeuler/kernel/issues/IAHMJO Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit d92467ad9d9ee63a700934b9228a989ef671d511 upstream. When boost is set for CPUs using acpi-cpufreq, the policy is not updated which can cause boost to be incorrectly not reported. Fixes: 218a06a79d9a ("cpufreq: Support per-policy performance boost") Link: https://patch.msgid.link/20240626204723.6237-2-mario.limonciello@amd.com Suggested-by: Viresh Kumar <viresh.kumar@linaro.org> Suggested-by: Gautham R.
