While reading the Arm Firmware Framework for Armv8-A https://developer.arm.com/documentation/den0077/latest
I do not find the API that for a sp to request vIRQ, or do I miss something.
Is this some private API that is implementing defined FF-A IDs?
Is what you have in mind is an ABI that allows SP0 to raise an interrupt in SP1?
Could you please provide more information about your use case?
I mean a sel1-firmware-driver SP. How does it to enable and request vIRQ from ff-a ABI?
