* About *
The Qualcomm SDM845 SoC has a separate SLPI (Sensor Low Power Island)
DSP for sensors connected to the SoC which is responsible for exposing
sensors to userspace, power saving, and other features.
While sensors are connected to GPIOs of the SoC, they cannot be used
because the hypervisor blocks direct access to the sensors, thus the
DSP must be used to access any sensor on this SoC. The SLPI DSP uses a
GLink edge (dsps) to communicate with the host and has a FastRPC interface
to load files from the host filesystem such as sensor configuration files.
The FastRPC interface does not use regular FastRPC Compute Banks
but instead uses an allocated CMA region through which communication happens.
* Changes *
This patchseries adds support for this remoteproc in the q6v5_pas driver
to allow booting the SLPI on the SDM845 and expose its service 400 over QRTR.
* Related patches *
Support for the FastRPC side of the SLPI and DTS changes are submitted
in separate series. These are the links to v2 of the series:
1. FastRPC changes:
https://lore.kernel.org/linux-arm-msm/20230327184204.498032-1-me@dylanvanassche.be/
2. DTS changes:
https://lore.kernel.org/linux-devicetree/20230327184811.499553-1-me@dylanvanassche.be
* Changelog *
Changes in v2:
- Removed double blank lines
- Added power-domain if:then: for SDM845 SLPI
- After adding SDM845 SLPI, refactor SLPI resource init
Changes in v3:
- First refactor SLPI resources of SM8150/SM8250/SM8350/SM8450/MSM8996/MSM8998,
then add support for SDM845 SLPI.
- Add Reviewed-by for patch
'dt-bindings: remoteproc: qcom: adsp: add qcom,sdm845-slpi-pas compatible'
since it was not changed in v3.
Kind regards,
Dylan Van Assche
