qat_mem non root access

I building QAT1.6 driver and openssl-async. All working fine, butas root.

I have tried:

chmod g=rw /dev/icp_*

chgrp ${GROUP} /dev/icp_*

chmod g=rw /dev/qat_mem

chgrp ${GROUP} /dev/qat_mem

butgetting the followingerror:

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?
