PerformanceCounterPlugin

class PerformanceCounterPlugin extends FiberPlugin with PerformanceCounterService

This plugin implement the performance counters in a very tricky way to save area. The RISC-V spec specified 64 bits per counter, and that is kinda expensive to implement FPGA. So in this implementation, Only 8 bits registers are used for each counters, which are flushed into their 64 bits CSR ram when their MSB is set

To figure out the actual performance events implement in VexiiRIscv, look at vexiiriscv.misc.PerformanceCounterService
