  • Writes to HPMCOUNTERs are now single-issued
  • MCONTROL6: The 32 MSBs of the address were masked when setting a breakpoint

  • Update fence instruction to stall until write-buffer and current snoop access has completed
  • hfence instruction did not cause illegal instruction exception when executed in U-mode
  • PMPCFG: change behavior on illegal NA4 mode
  • CBO: did not stall until tag update was completed. Forwarding for address generation was not correct
