+
+  On RISC-V systems, the HARTs (or CPUs) [6] can be put in platform specific

+  The platform specific suspend (or idle) states of a hart can be either

+  preserve HART registers and CSR values for all privilege modes whereas
+  a non-retentive suspend state will not preserve HART registers and CSR
