Hello Dwaine, I finished my work to add SMP support to the RISC-V architecture for RTEMS. It is now on par with the ARM, PowerPC and SPARC ports. I had only a two hart system for testing (FPGA based). It would be nice to get some funding to add support for high end targets such as: https://w

Hello Molock, we work currently on the SMP support for RISC-V (32-bit and 64-bit). The aim is to run the tests on Qemu and a FPGA Board with two BOOMv2 processors. https://devel.rtems.org/ticket/3433 My current task is a tool chain update to include a bug fix for: https://sourceware.org/bugz
