From f1c1dc6b10040470bcf357ebac41b41553931d0a Mon Sep 17 00:00:00 2001 From: Anshu Gahire <105154048+FosRexx@users.noreply.github.com> Date: Mon, 6 May 2024 17:43:38 +0545 Subject: [PATCH] Fix spam error message when setting energy_performance_preference (#680) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Fix spam error message when setting energy_performance_preference The 'intel_pstate' driver does not allow the EPP to be set to anything but 'performance' when the scaling governor is set to 'performance', previously auto-cpufreq when the scaling-governor was set to 'performance' tried to set the EPP to 'balance-performance' which caused a spam of write error messages in journalctl in system with 'intel_pstate' drivers. This is an intended behavior, since according to the [kernel documentation](https://docs.kernel.org/admin-guide/pm/intel_pstate.html#hwp-performance) when HWP is enabled[(which is enabled by default during boot with supported processors)](https://docs.kernel.org/admin-guide/pm/intel_pstate.html#active-mode-with-hwp) and scaling governor is set to performance the processor’s internal P-state selection logic is expected to focus entirely on performance. And this will override the EPP setting and reject any value different from 0 (“performance”). This commit just changes the 'balance-performance' EPP preference in set_performance() to 'performance'. Which fixes the spam issue. * Only applies the spam error message fix for intel_pstate drivers * Comparing the content of the file intel_pstate/staus to make sure the condition only applies when "active" * Override custom config EPP to "performance" for intel_pstate driver --- auto_cpufreq/core.py | 37 ++++++++++++++++++++++++------------- 1 file changed, 24 insertions(+), 13 deletions(-) diff --git a/auto_cpufreq/core.py b/auto_cpufreq/core.py index e61fa33..58cedb7 100755 --- a/auto_cpufreq/core.py +++ b/auto_cpufreq/core.py @@ -113,14 +113,14 @@ except PermissionError: # Current work-around for Pop!_OS where symlink causes permission issues print("[!] Warning: Cannot get distro name") if os.path.exists("/etc/pop-os/os-release"): - # Check if using a Snap + # Check if using a Snap if os.getenv("PKG_MARKER") == "SNAP": - print("[!] Snap install on PopOS detected, you must manually run the following" - " commands in another terminal:\n") + print("[!] Snap install on PopOS detected, you must manually run the following" + " commands in another terminal:\n") print("[!] Backup the /etc/os-release file:") - print("sudo mv /etc/os-release /etc/os-release-backup\n") + print("sudo mv /etc/os-release /etc/os-release-backup\n") print("[!] Create hardlink to /etc/os-release:") - print("sudo ln /etc/pop-os/os-release /etc/os-release\n") + print("sudo ln /etc/pop-os/os-release /etc/os-release\n") print("[!] Aborting.
