+ * If the cache coherency attribute (CCA) is set to zero, it's a write through cache, there is no need

* In the latest MIPS32/64 CPUs, MIPS provides the synci instruction,

- * That is, it arranges a D-cache write-back and an I-cache invalidate.
+ * That is, it arranges a D-cache write-back (if CCA = 3) and an I-cache invalidate.
*
- * To employ synci at user level, you need to know the size of a cache line,
- * and that can be obtained with a rdhwr SYNCI_Step
- * from one of the standard “hardware registers”.
