Since last testing this interesting SBC on 7.6 (where OpenBSD had many
problems while running the MP kernel but ran stable on the SP kernel)
the experience has changed.
Everything appears to behave OK with the MP kernel now. No more random
process crashes while reading/writing over the microSD port. The kernel
still reports that the SoC is firmly locked to 800 MHz instead of its
maximum frequency of 1.6 GHz. No apparent way of changing the freq. as
both hw.perfpolicy and hw.setperf are unavailable.
Network throughput is a little bit higher due to the new parallelism,
and would likely saturate its GbE if it weren't running at half clock:
--- 192.168.15.2 tcpbench statistics ---
1519510704 bytes sent over 21.004 seconds
bandwidth min/avg/max/std-dev = 576.061/578.752/580.331/1.096 Mbps
--- tcpbench server statistics ---
1114786984 bytes received over 21.706 seconds
bandwidth min/avg/max/std-dev = 417.475/424.616/430.857/3.539 Mbps
This is still booting off vanilla u-boot 2025.04 as there's no official
support for it yet. I'd be happy to try any suggestions or patches to
see if it's possible to get its clock up over 800 MHz.
