I building QAT1.6 driver and openssl-async. All working fine, but as root.
I have tried:
chmod g=rw /dev/icp_*
chgrp ${GROUP} /dev/icp_*
chmod g=rw /dev/qat_mem
chgrp ${GROUP} /dev/qat_mem
but getting the following error:
mmap: 11 Resource temporarily unavailable: Resource temporarily unavailable
crypto_alloc_from_slab error, create_slab failed - memory allocation error
How do i allow non-root access to qat_mem?

And what is the difference between qat_mem and qae_mem? Which driver is recommended to use? I did not find this in the documentation.
