Why would the instruction set used by the kernel matter, when video encoding is done in userspace? You would get more improvement if you recompiled the software that does the video encoding - and as I mentioned, it won't help unless the compiler knows about the opcodes *and* can recognize the spots in the userspace code where those opcodes would be useful. --==_Exmh_1646348815_14564P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Comment: Exmh version 2.9.0 11/07/2018 iQEcBAEBCAAGBQJiIUoPAAoJEI0DS38y7CIcUy8H/1RyFW6T5RPmNw1ZIInrOQly vvwXhsI/2L9Jam4bL98W8tLQit3WsDQx1bDY0gMsIkZNs661jc/pVMPOLxX+Dd/w U17lbU5YUnL3M8c0iBujJp9bv/PtWYHxrJOi0Gmszc7ftXsCF166HaagmyH7t/hk wsazEU1OjdznykTJNUTWwMv3L5NCnY1IzpRWASxO/Yl0B1Ut5XcDxqI7VEOQoVHl 69NEsLFMgL7YMJcqNb6dQrVIiXyICgmV85hDvtKj/1ixM5CvXsB8//9zNn4CgpNv mZs4r3x6etWxS8dfUanTlC4IvRtx/w8oiyNkJ+X1ekxPoyjMvV+7atjDS3awgtc= =IYHO -----END PGP SIGNATURE----- --==_Exmh_1646348815_14564P-- --===============8393993453048824443== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies --===============8393993453048824443==--
