I haven't read the complete history of Gunyah yet, but from a quick
look it uses the hvc/smc instruction as the "physical link" between
entities (?).    zynqmp-ipi-mailbox.c is one driver that uses smc in
such a manner. And I know there are some platforms that don't call
hvc/smc under mailbox api and I don't blame them.

Let me educate myself with the background and get back.... unless you
want to summarize a usecase that you doubt is supported.
Hi Jassi,

Did you have chance to evaluate? I have given a summary in this mail, especially the last paragraph:
