Hi Daniel, - L1 D$ clean ( SCTLR C bit clear, DCCISW, clear SMP) is part of the recommended sequence for Individual core power down . - If a core is powered down having dirty lines in L1 then the system should encounter an issue (abort) very easily. May be the first

? flush_cache_louis does not disable the d cache. This is not the recommended sequence for core power down. Thanks Sandeep Tripathy Broadcom ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
