Date: Sat, 12 Oct 2013 19:16:59 +0530 From: Ryan <ryanphilips19@...glemail.com> To: linux-kernel@...r.kernel.org Subject: smp questions 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?
