## Summary Implements SMP support for the Raspberry Pi 4B on all four cores using the SMP spin tables on the BCM2711. ## Impact Users can leverage all four cores on NuttX now! 4x more powerful. Closes #16954. Part of GSoC #18507! ## Testing OSTest and the SMP test run successfully on the RPi4B. However, there are artifacts in the early boot logging information on startup. I suspect this is because all cores are starting from `_start` and competing to print the early output before spinlocks are used to protect the console. **logs coming soon** Any advice on a better jump point to start the cores is appreciated! Not sure if there are any other examples of spin-table SMP devices in the NuttX tree (or at least, I haven't found them). -- This is an automated message from the Apache Git Service.
