Linux ACPI and power management maintainer Rafael Wysocki today sent out all of the feature updates and changes intended for the now-started [1]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 [2]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 [3]thermal updates for Linux 6.18 include:
- Support for [4]the new Intel Power Slider feature with the int340x thermal driver. This Power Slider additional is [5]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 [6]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 [7]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.
