The Libre-SOC Project aims to develop a family of OpenPOWER processors, ultimately working towards a full hybrid 3D CPU-VPU-GPU. After two years of development funded by NLnet, the current phase is to develop a Gigabit Ethernet Router ASIC. Funded by NGI POINTER, this ASIC is intended to be capable of running OpenWRT with OpenPOWER-compliant RADIX Virtual Memory.

This talk will provide background, a status update, and go through the incremental development and debugging that is leading up to being able to boot a microwatt linux-5.7 kernel with a buildroot initramfs, under verilator.
