Hello, SMP support for Raspberry Pi 3 is in usable state now. I didn=E2=80=99t = run any load tests, only checked that all four cores are started on boot. Short instruction: - Build GENERIC arm64 kernel for your image, not GENERIC-UP - Copy https://people.freebsd.org/~gonzo/arm/rpi3-smp/u-boot.bin and https://people.freebsd.org/~gonzo/arm/rpi3-smp/armstub8.bin to FAT partition on SD card. - Edit config.txt: change value of device_tree_address parameter: device_tree_address=3D0x4000 - Reboot device. It should boot with all four cores enabled and reboot should work too. More detailed description of what all these binaries/changes contain is in these two posts: https://kernelnomicon.org/?p=3D714 https://kernelnomicon.org/?p=3D718 Please note that FreeBSD/arm64 has been broken by clang 3.9.0 import and you will have to update aarch64-binutils to the 2.27_5 to get it booting.
