All,
For a given platform, the CPU and the PCH are being enumerated along the ACPI bus. We have been using polling for temperature thresholds trip points. Now, we are looking to use interrupts instead. I haven't seen too many examples of of acpi drivers with interrupts enabled. Any suggestions on where to start? Any templates I can use?
Thanks and regards,

Hi,
If you are going to write a driver using level-triggered GPEs, please wait until some useful GPE API fixes being merged.
Thanks and best regards

I think you can have a look at EC driver which uses GPE as its interrupt.
