Re: A proposal to enhance RISC-V HPM (Hardware Performance Monitor)


Hi all,

Although there were some non-resolved discussions, it has little to do with what we should do for the next step.  I believe Greg's proposal is superior to the original one in the starting thread because

1.  It reuses `hpmevents` for most of the functions that we all agree that RISC-V needs, instead of adding a bunch of new registers.
2.  It is H-ext-aware

I suggest Greg take the lead to start a PR in the ISA Repo, I can help review and evaluate the effort to patch existing software.
