Currently the Px Cx supported SoCs which listed in cpu_state_tbl.c is limited, and it is not a wise option to build a huge state table data base to support Px/Cx for other SoCs. This patch give a alternative solution that build a board specific cpu state table in board.c which could be auto-generated by offline tool, then the CPU Px/Cx of customer board could be enabled; Hypervisor will search the cpu state table in cpu_state_tbl[] first, if not found then go check board_cpu_state_tbl. If no matched cpu state table is found then Px/Cx will not be supported; Tracked-On: #3477 Signed-off-by: Victor Sun <victor.sun@intel.com> |
