fan_zero_rp..._temperature(9)
π NAME π
okay so this is fan_zero_rp..._temperature(9) β the manual page (Kernel API Manual, section 9, bestie π
) for fan_zero_rpm_stop_temperature. it's the amdgpu sysfs knob for the zero RPM stop temperature feature, and honestly? it's giving "tiny file, big vibes" β¨
πΈ DESCRIPTION πΈ
so the amdgpu driver ships a sysfs API for checking and adjusting the zero RPM stop temperature feature β that's the whole point of this file, no cap π«Ά
reading back the file shows you the current setting, plus the permitted ranges if they're changeable π (yes, if β some things aren't, and the file will tell you)
writing an integer to the file changes the setting accordingly β literally just drop a number in there π
when you've finished editing, write "c" (commit) to the file to commit your changes. no commit, no change, fr fr π
and if you wanna reset to the default value, write "r" (reset) to the file to reset them π§
β οΈ heads up: this setting works only if the Zero RPM setting is enabled. it adjusts the temperature below which the fan can stop. that's it, that's the whole job β no Zero RPM, no party π

that's the whole friend group, go say hi π
β¨ sign-off time β¨ this lil page lives in ./drivers/gpu/drm/amd/pm, dated October 2026, and it's part of the Kernel API Manual. mwah, go touch some fan curves ππ₯π
