None of the commit messages explains, why do we want it on the image. |
Add qcom-rtss-mailbox-kmd, the kernel driver (DLKM) that exposes the RTSS mailbox hardware interface to userspace via a UAPI, enabling IPC between the APSS (Application Processor SubSystem) and the RTSS (Real-Time SubSystem). The device tree overlays (lemans-rtss-mb.dtbo, monaco-rtss-mb.dtbo) already enable the hardware side; this package brings the kernel software stack that makes the mailbox interface accessible to applications.

Add the userspace middleware stack built on top of the RTSS mailbox KMD,
completing the full APSS-to-RTSS IPC software stack:
- qcom-rtss-mailbox-umd: provides librtss_mailbox (mailbox IPC
library) and librtss_safemlib (safe messaging library)
- qcom-rtss-ota: provides librtss_ota, an OTA SDK for pushing
firmware updates to the RTSS
- qcom-rtss-mailbox-umd-utils: ships debug/test utilities
(rtssdbg, rtss_console, rtss_mbdemo)
Together with the KMD, these packages give applications a complete path
to communicate with and update firmware on the RTSS.

Also, this depends on these 2 KMD & UMD Recipes changes, so will keep in draft state for now, till these 2 have merged. |
It still doesn't explain, what is it for and why. What is the benefit of the RTSS? Why do we need to communicate with it? etc. |
sargarram7 Could you please help answer the above queries for your RTSS driver ? |
