Hi Experts,

I am moving from device tree world to acpi. I found the event notification
feature of acpi table interesting.

I have some questions over notification
-  Is some hardware can generate events and notify OS by its own ?(if yes ,
please help me how) , I mean without calling any method from OS

- I may be wrong, but it looks OS needs to call a method in order to
execution of Notify function of acpi table

- Is this correct acpi tables are static piece of code, having no
thread/execution context, All execution in done from OS


Thanks
Kumar G
