Hi Marc,
This is from Nianyao Tang.
I'm planning to do some verification on our GIC-v4.1 implement. I would like some
information about linux GIC-v4.1 driver. When will linux support GIC-v4.1 or what's
the plan on developing GIC-v4.1 driver?
Thanks,
Nianyao.

The easy answer is that yes, there is a plan. There is some code, even,
just not quite in a usable state yet. I'll try to push something out
once I get a chance.

FWIW, I've pushed out a branch containing the current state of this work
at [1]. It doesn't really work at the moment (Doorbells and SGIs are
unreliable), but hopefully that will give you an idea of what is going on.
Being a work in progress, it is unstable, subject to being changed,
rebased and deleted without warning.
Thanks,
M.

Thank you, it is really helpful. I will check on this code first. If have any doubt,
I will 'noise' you again ;-)
Thanks in advance,
