The automotive world is rapidly moving towards software defined vehicles & zonal architecture. Ethernet is the backbone of zonal architecture. The bandwidth and response time requirements of ethernet are higher than ever. The network stack with Linux makes it a compelling choice of OS for Gateway/ADAS SOCs.

With growing number of ECUs in the car, the gateway SOC needs to be ethernet ready very early to support FOTA and telematics applications. All the ECUs sitting behind the gateway need ethernet functionality for communication. With ROM code, boot loader kernel & the user space application taking time to initialize, the goal of early ethernet is a tricky one.

The presentation aims to cover the optimizations done at each phase of the Linux boot to achieve early ethernet. Top level optimizations:

1. Streamlined the boot flow from bootloader to get to Linux kernel faster.
2. Opening the network device early with driver optimization allows the hardware to be initialized early
3. Configuring majority of network using networkd scripts allows the interfaces to be ready early

Although the demonstration is done using TI's DRA821 Gateway SOC, this is applicable to any SOC using Linux.
