Hi all, I found that the cache policy in after ARMv6 is always set as writeback mode in mmu.c. static int __init early_cachepolicy(char *p) { ... if (cpu_architecture() >= CPU_ARCH_ARMv6) { printk(KERN_WARNING "Only cachepolicy=writeback supported on ARMv6 and later\n"); cachepolicy = CPOLICY_WRITEBACK; } ... } Does anyone know why and provide some documents or links for that? Thanks so much! Cheers, Jacky
