Yes, at least: dd if=/dev/hwrng of=/dev/null bs=1024 count=1024 shows a higher speed than without the patch. > It's missing a signed-off-by:, btw I did not know we are already that far ;-) I mean: can this patch be aplied without hurting C3/C7 CPU's with just one RNG? Maybe an expert needs to test/answer? Maybe some logic needs to be applied around the extra bit?
