Linux ACPI and power management maintainer Rafael Wysocki today sent out all of the feature updates and changes intended for the now-started Linux 6.18 merge window. There are some new Intel additions as well as for the growing range of different ARM-based SoCs and other hardware.
The power management pull request for Linux 6.18 includes:
– Updating the Intel P-State driver to allow it to enable Hardware P-States (HWP) without Energy Performance Preference (EPP) when the new Dynamic Efficiency Control (DEC) hardware feature is enabled.
– Support for the AN7583 SoC within the Airoha CPUFreq driver.
– Support for the IPQ5424 in the Qualcomm NVMEM CPUFreq driver.
– Support for the MT8196 within the MediaTek hardware CPUFreq driver.
– Support for the AM6202 in the TI CPUFreq driver.
– Many bug fixes to the different power management drivers.
Meanwhile the thermal updates for Linux 6.18 include:
– Support for the new Intel Power Slider feature with the int340x thermal driver. This Power Slider additional is initially going to be found with Panther Lake laptops.
– Support for the Renesas RZ/G3E and RZ/G3S SoCs via a new Renesas thermal driver.
– A new Tegra114-specific SoC thermal driver.
– Documenting the Qualcomm Glymur temperature sensor in qcom-tsens for the newly-announced Snapdragon X2 Elite.
– Updating the step-wise thermal governor to let it reduce the cooling level earlier if the thermal zone temperature is dropping.
Lastly are the ACPI updates for Linux 6.18:
– Adding the SoundWire File Table “SWFT” signature to the ACPICA code.
– Various hardware quirks and other fixes.
Those are the main thermal and power management highlights of what has been submitted so far for Linux 6.18.
