How to collect looppoint of riscv specCPU2017 in gem5

[qqli579]

Hi everyone,
I want to collect specCPU2017 multi-core looppoint in gem5. I referred to the file https://github.com/gem5-hpca-2023/gem5-tutorial-codespace/blob/master/materials/looppoints/create-looppoint-checkpoints.py. But I'm a little confused about this:

board.set_se_looppoint_workload(
    binary=obtain_resource("x86-matrix-multiply-omp"),
    arguments=[100, 8],
    looppoint=LooppointCsvLoader(
        pinpoints_file="materials/looppoints/refs/looppoint-pinpoints.csv"
    ),
)

For the binary here, I should enter the compiled bin file of a certain case of specCPU2017, but I don’t understand what the pinpoints_file is? Or how is this file generated?
I saw in the looppoint-pinpoints.csvlooppoint-pinpoints.csv file:

Regions based on: /home/alen/isca2022/looppoint/tools/sde-external-9.0.0-2021-11-07-lin/pinplay-scripts/pcregions.py --label_file t.labels --warmup_factor 2 --tid global --bbv_file t.bb --region_file t.simpoints --weight_file t.weights

Is this file generated using the pcregions.py script file?
