The running time that I use make TARGET=riscv64 to run coremarkpro is 0 in the output log file

[LiHao217]

Hello, when I use make TARGET=riscv64 to run coremarkpro, it shows that the running time is 0 in the output log file, and the output is correct when running make TARGET=linux64,

Can you help me to solve the mistake I have make ? Thanks

That's because the proxy kernel (https://github.com/riscv/riscv-pk) doesn't implement clock_gettime. Either implement that syscall, or modify the coremark-pro port to use the appropriate CSRs to read the time.
