  • Introduce VBSA CLI option -el1skiptrap pmsidr and g_el1skiptrap_mask to bypass PMSIDR_EL1 reads that may trap at EL1
  • Guard the reg access in pe001.c. Behaviour of the test is unchanged unless CLI parameter is passed
  • deprecate -el1physkip option that dupclicates -el1skiptrap functionality
  • guard EL1 physical counter accesses using -el1skiptrap
