![]() The use of AMU counters at the highest implemented exception level can expose information about them to lower exception levels, such as specific behavior happening in the CPU (e.g.: MPMM gear shifting in TC2). In order to prevent this, read accesses to AMU counters are restricted by default, so they are RAZ (read-as-zero) from lower exception levels from now on.
