Not sure on this one, initially I thought of a sysfs file, but then how would you do it. One "global" sysfs entry is probably a bad idea. Having one per block device to select native vs emulation maybe? And a good way to benchmark. The other idea would be a benchmark loop on boot like the raid library does. Then on the other hand, there might be workloads that run faster with the emulation and some that run faster with the hardware acceleration. I think these points are the reason the last attempts got stuck. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
