            Bug ID: 294
           Summary: usage statistics needed for POWER9 architecture
           Product: Libre-SOC's first SoC
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: CONFIRMED
          Severity: enhancement
          Priority: ---
         Component: Source Code
          Assignee: lkcl at lkcl.net
          Reporter: lkcl at lkcl.net
                CC: libre-riscv-dev at lists.libre-riscv.org
   NLnet milestone: ---

we need to specifically target the register file port allocation and
the bus multiplexing to meet the performance requirements.  we cannot
go all-out because the power consumption and wiring would be far too
high.
