Alan,

I'm fine with taking the lead on this architecture extension.  But it should follow a proper process as directed by the TSC.  Thus far this would mean getting a new TG created or doing something less formally under an existing TG.  But for smaller extension proposals like this there is need for a proper lighter weight and faster process.  Need for this is recognized and I suspect will probably be promulgated by the TSC some time soon.

So I suggest we pause for a short bit, and then see if we can follow that expedited process once it is available.  In the meantime I/we can prepare what we can in advance.  (I don't think this will represent a material slow down to getting to a frozen spec and then to ratification.)

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.

Thanks,
Alan
