1. If anyone out there is running dsl on a recent-ish VIA processor, I'd be interested in hearing how VIA padlock hw encryption works with this extension.
Since loop-aes is already very fast with software encryption only on a fast-ish processor, one way to tell the difference might be to run the earlier version of this extension and copy a very large file to an aes128 encrypted partition, timing the write speed.
Then - umount the encrypted partition, install this extension over the earlier one (replacing the loop driver), do rmmod loop and then modprobe loop to insert the newer driver, mount the partition and then copy the same file across again, also timing the write speed.
AES encrytion should be very much faster (I think) with VIA Padlock.
On VIA hardware, loop-aes should detect and enable aes padlock support automatically.
For info see http://www.via.com.tw/en/initiatives/padlock/whyhardwareisbetter.jsp
FYI enabling this support has no effect on running this extension on other hardware.
2. Since compiling this there has been another sub-minor version release of loop-aes (v3.2c). Afaik this contains no changes of relevance to dsl unless you're using /etc/fstab to manage your loop-aes encrypted partition and you have symlinks in /etc/fstab. (NB tripl doesn't use /etc/fstab).
