Re: [PATCH 4/4] Add AES [Enc|Dec] optimized implementations for PowerPC64

You are right, I measured the throughput and latency for vncipher and vxor instructions for POWER8 and updated the patch accordingly. On Thu, Jul 9, 2020 at 5:58 PM Niels Möller wrote: > Maamoun TK writes: > > > +L16x_round_loop: > > + lxvd2x KX,10,KEYS > > + vperm K,K,K,swap_mask > > +

[PATCH 2/6] "PowerPC64" Add optimized AES [Enc|Dec]

I measured the latency and throughput of vcipher/vncipher/vxor instructions for POWER8 vcipher/vncipher throughput 6 instructions per cycle latency 0.91 clock cycles vxor throughput 6 instructions per cycle latency 0.32 clock cycles So the ideal option for POWER8 is processing 8 blocks, it has
