Subject: [RFC][PATCH 0/2] reworking cause_ipi and adding global doorbell support
Date: Mon, 13 Mar 2017 03:13:25 +1000 [thread overview]
Message-ID: <20170312171327.21088-1-npiggin@gmail.com> (raw)
Hi,
Just after the previous two fixes, I would like to propose changing
the way we do doorbell vs interrupt controller IPIs, and add support
for global doorbells supported by POWER9 in HV mode.
After this, the platform code knows about doorbells and interrupt
controller IPIs, rather than they know about each other.
Thanks,
Nick
