Of course, it is totally untested... ;-) But I like that the doorbell request is solely driven by the WFI state, and we avoid leaking the knowledge outside of the vgic code.

I have tested this approach and it also solves the issue. Please feel free to add: Tested-by: Xiang Chen chenxiang66@hisilicon.com

Excellent, thanks for testing a couple of iterations for us here. Marc, do you want to add a changelog to this?

Done [1]. I've nicked most of your changelog, so you get a CDB tag ;-)

Thanks,
