3.10.20 HPBASE: Hot Page Range Base
This register contains the base address used to index the Hot Page counter array. A 2K-entry
counter array can scan up to 512 GB of contiguous physical addresses when the address resolution
is 256 MB.
3.10.21 HPMAX: Hot Page Max Range Address
This register contains the maximum range address used to index the Hot Page counter array when
in the AutoRange mode. When the Hot Page Range counter exceeds this value, the Range counter
is reloaded with the value in the Hot Page Range Base register (HPBASE).
