Status in linux package in Ubuntu: Invalid Status in linux source package in Jammy: Fix Committed Bug description: This is a public version of the following bugs: https://bugs.launchpad.net/bugs/1987597 https://bugs.launchpad.net/bugs/2027754 ---------------- [Feature Description] We need Fine-grained Control of TFN participant for enabling active 2 policy in Linux/chrome. Currently, The kernel has provided __FPS table and cur__state to adjust the fan level as per _FPS table . But there is no option to read *_FIF (Fan Information) and _FST (Fan Status).* Once the fine-grained control is enabled, we should be able to the set the control value from 0-100 through Arg0 of _FSL (Fan Set Level). *_FST (Fan Status)* should report current running RPM and control value of the FAN(TFN). please refer ACPI spec for more detail.
