RISC-V is now an official Debian architecture. After Debian approves the official support architecture for RISC-V, there may be many dependencies on Debian open source projects to complete support for RISC-V in a short period of time.
The last post shows a CoreMark of 4826.254826 (or 3.22 CoreMark/MHz) for 1 HART of the JH7110: CoreMark 1.0 : 4826.254826 / GCC12.2.0 -O2 -DPERFORMANCE_RUN=1 -lrt / Heap
I compiled CoreMark about a month ago and got a 24% higher result by tweaking the compiler options to use all the available features of the U74-MC in the JH7110 SoC: CoreMark 1.0 : 5976.961530 / GCC12.2.0 -O2 -march=rv64imafdc_zicsr_zifencei_zba_zbb -mcpu=sifive-u74 -mtune=sifive-7-series -mabi=lp64d -O3 -DPERFORMANCE_RUN=1 -lrt / Heap
CoreMark of 5977 or 3.985 CoreMark/MHz for 1 HART of the JH7110

analyzing CPU 0:
driver: cpufreq-dt
CPUs which run at the same hardware frequency: 0 1 2 3
CPUs which need to have their frequency coordinated by software: 0 1 2 3
maximum transition latency: Cannot determine or is not supported.
hardware limits: 313 MHz - 1.50 GHz
available frequency steps: 313 MHz, 375 MHz, 417 MHz, 500 MHz, 625 MHz, 750 MHz, 1.25 GHz, 1.50 GHz
available cpufreq governors: conservative ondemand userspace powersave performance schedutil
current policy: frequency should be within 313 MHz and 1.50 GHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency: 1.50 GHz (asserted by call to hardware)
