Subject: [PATCH v2 0/7] Add audio driver base on rpmsg on i.MX platform
Date: Sun, 7 Feb 2021 18:23:48 +0800 [thread overview]
Message-ID: <1612693435-31418-1-git-send-email-shengjiu.wang@nxp.com> (raw)
On Asymmetric multiprocessor, there is Cortex-A core and Cortex-M core,
Linux is running on A core, RTOS is running on M core.
The audio hardware device can be controlled by Cortex-M device,
So audio playback/capture can be handled by M core.
Rpmsg is the interface for sending and receiving msg to and from M
core, that we can create a virtual sound on Cortex-A core side.
A core will tell the Cortex-M core sound format/rate/channel,
where is the data buffer, what is the period size, when to start,
when to stop and when suspend or resume happen, each of this behavior
there is defined rpmsg command.
Especially we designed the low power audio case, that is to
allocate a large buffer and fill the data, then Cortex-A core can go
to sleep mode, Cortex-M core continue to play the sound, when the
buffer is consumed, Cortex-M core will trigger the Cortex-A core to
wakeup to fill data.
changes in v2:
- update codes and comments according to Mark's comments
