Hello, I'm using https://github.com/eugene-tarassov/vivado-risc-v to run a Linux system with on a VC707 FPGA Board. I'm using the config with 3-wide superscalar Large BOOM, 1 core(rockey64y1).
I wonder whether the core is implemented with mhpmcounter3 to mhpmcounter31? I assigned the value 0xffffffff to the mcounteren control register, but the readout value is 0x00000007. Does this imply that Rockey64y1 only supports 'instructions', 'time', and 'cycles' in perf events?
