Subject: [PATCH 0/4 v2] doorbell patches for POWER9
Date: Thu, 13 Apr 2017 20:16:20 +1000 [thread overview]
Message-ID: <20170413101624.26628-1-npiggin@gmail.com> (raw)
Since last:
- Ported up to powerpc next (thanks mpe)
- Dropped darn workaround from DD1 for now.
- Dropped the guest doorbell hack. It's not an immediate problem and
will be tackled in other ways.
Nicholas Piggin (4):
powerpc: change the doorbell IPI calling convention
powerpc: Introduce msgsnd/doorbell barrier primitives
powerpc/64s: avoid branch for ppc_msgsnd
powerpc/powernv: POWER9 support for msgsnd/doorbell IPI
