| The Marvell 88f5182 have a cryptographic hardware (named "CESA") thing that is allowing to reduce CPU usage while dealing with crypto stuff. If you check in the kernel, you'll see that this crypto hardware access is done using [[http://ocf-linux.sourceforge.net/|OCF]]. | The Marvell 88f5182 have a cryptographic hardware (named "CESA") thing that is allowing to reduce CPU usage while dealing with crypto stuff.

| A guy from Marvell did post a dm-crypt.c patch to allow using OCF for encrypted partitions, I didn't checked DNS323's kernel source, but I don't think that this patch have been applied on it ... | A guy from Marvell did post a dm-crypt.c patch to allow using OCF for encrypted partitions, I didn't checked DNS323's kernel source, but I don't think that this patch have been applied on it ... | ||

| + | I think the speeds measured in the article do not make much sense unless you know the speed of unencrypted disk access on the same hardware. [[wiki:user:icks]] | ||
