Subject: [PATCH 0/2] Add support for DSP IPC protocol driver
Date: Fri, 14 Jun 2019 16:16:48 +0800 [thread overview]
Message-ID: <20190614081650.11880-1-daniel.baluta@nxp.com> (raw)
From: Daniel Baluta <daniel.baluta@nxp.com>
Hifi4 DSP can be found on some i.MX8 platforms (e.g i.MX8QXP, i.MX8QM).
This patch series introduces the layer that allows Host CPU to
communicate with DSP.
This layer provides a doorbell and clients can used that to notify DSP
that a message is placed somewhere in the shared memory.
The protocol used is request - reply. Usually, Host/DSP write a message
in a shared memory area and notify the other side. The other side will
also write a reply in a designated shared memory area and then ring
the doorbell to let the counterpart that a message is ready.
