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