Implement Safety with a RTOS Running as a Linux Companion Within...
summary
Demonstrates a concrete architecture running Zephyr on a Cortex-R7 dual‑lockstep core for safety functions and Linux on A57/A53 cores of a Renesas R‑Car Gen3, using OpenAMP hardware mailbox for IPC; implements lightweight container isolation (bubblewrap/redpack) on Linux, Mander for OTA, and eBPF for kernel introspection. Claims this isolates certifiable RTOS code (much smaller doc burden) while keeping Linux for networking/UI; notes CVE fix targets of 30–90 days vs current 2–4 year reality and reports successful integration on the SoC.
