--- Comment #2 from Li Pan <pan2.li at intel dot com> --- Take x86_64 perf data for 625 base, x264_pixel_satd_8x4 is the hottest func. Children Self Command Shared Object Symbol + 19.26% 18.96% x264_s_base.non x264_s_base.none [.] x264_pixel_satd_8x4 + 18.95% 2.39% x264_s_base.non x264_s_base.none [.] refine_subpel + 13.90% 13.71% x264_s_base.non x264_s_base.none [.] get_ref + 8.97% 8.90% x264_s_base.non x264_s_base.none [.] mc_chroma I will try to take care of this for the RISC-V backend.
