       - `amdgpu` kernel driver overdrive mode can now be enabled by setting [hardware.amdgpu.overdrive.enable](#opt-hardware.amdgpu.overdrive.enable) and customized through [hardware.amdgpu.overdrive.ppfeaturemask](#opt-hardware.amdgpu.overdrive.ppfeaturemask).

       32

         This allows for fine-grained control over the GPU's performance and maybe required by overclocking softwares like Corectrl and Lact. These new options replace old options such as {option}`programs.corectrl.gpuOverclock.enable` and {option}`programs.tuxclocker.enableAMD`.
