Sorry, didn't comment this earlier.

Those threads are independent including MEMCPY stuff.
I think it's better to have one additional parameter let's say
type_of_test where you can set
1 for MEMCPY
2 for XOR
4 for PQ

Share this parameter via debugfs and use 0x07 as default value.
I doubt we need this as a module parameter.
