Hello!

Yes, i do. However i am waiting for prerequisites (base vGICv3 in qemu and ITS
emulation in kernel to get in). I don't like to post patch-on-patch-on-patch
because i'm in doubt anyone would be bothered, neither it's useful.
But, ok, since you request it, i'll post it after vGICv3 v13, which will
address latest comments.
I could also share my userspace implementation of the ITS. However it will not
work because Shlomo's TCG GICv3 does not have LPIs. It can be interesting for
any of you if you want to continue this work. It is very preliminary but i got
it to the point where it injects an LPI into the GIC. I wrote it when there was
no in-kernel ITS patches, i supposed to implement raw LPIs in kernel and ITS in
userspace, similar to GICv2m.
