Hello
+/* Read data from the RNG unit */
+static int cavium_rng_read(struct hwrng *rng, void *dat, size_t max, bool wait)
+{
+ struct cavium_rng *p = container_of(rng, struct cavium_rng, ops);
+ unsigned int size = max;
+
+ while (size >= 8) {
+ *((u64 *)dat) = readq(p->result);
+ size -= 8;
+ dat += 8;
+ }I think you could use readsq() This will increase throughput Regards LABBE Corentin
