NVMM acceleration is currently NetBSD host only so can only be tested on
NetBSD hosts. Unless Qemu is smart enough to allow a guest NetBSD to run
NetBSD to test NVMM in a nested Qemu I don't think its possible to otherwise
automatically test on Linux.
Is there a README or documentation on how to modify and run the tests?
With regard,
Reinoud
