HI,
I use a custom kernel for ARM Cortex A9. When i enable the following macros. it detects 2 cores
CONFIG_CACHE_L2X0=y CONFIG_CACHE_PL310_INSN_PREFETCH=y CONFIG_CACHE_PL310_DATA_PREFETCH=y CONFIG_CACHE_PL310_PREFETCH_DOUBLE_LINEFILL=y CONFIG_CACHE_PL310_PREFETCH_DROP=y CONFIG_CACHE_PL310_STANDBY_MODE=y CONFIG_CACHE_PL310_DYNAMIC_CLOCK_GATING=y
However, If i disable them it detects only One Core.
Any Idea why is this required?
Regards, Ryan
