10*413d6ed3SHaren Myneni	  provide access to accelerator coprocessors such as NX-GZIP and
11*413d6ed3SHaren Myneni	  NX-842. This config allows the kernel to use NX-842 accelerators,
12*413d6ed3SHaren Myneni	  and user-mode APIs for the NX-GZIP accelerator on POWER9 PowerNV
13*413d6ed3SHaren Myneni	  and POWER10 PowerVM platforms.
