James Almer	aca8ceb870	x86/vf_bwdif_init: limit AVX2 functions using 256bit vectors to cpus known to be fast with it Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago
James Darnley	073ec3b9da	avfilter/bwdif: add avx2 filter_line function 8-bit: 2.24x faster (1925±1.3 vs. 859±2.2 decicycles) compared with ssse3 10-bit: 2.00x faster (1703±1.7 vs. 853±2.0 decicycles) compared with ssse3	2 years ago

Lynne	bbe95f7353	x86: replace explicit REP_RETs with RETs From x86inc: > On AMD cpus <=K10, an ordinary ret is slow if it immediately follows either > a branch or a branch target. So switch to a 2-byte form of ret in that case. > We can automatically detect "follows a branch", but not a branch target. > (SSSE3 is a sufficient condition to know that your cpu doesn't have this problem.) x86inc can automatically determine whether to use REP_RET rather than REP in most of these cases, so impact is minimal. Additionally, a few REP_RETs were used unnecessary, despite the return being nowhere near a branch. The only CPUs affected were AMD K10s, made between 2007 and 2011, 16 years ago and 12 years ago, respectively. In the future, everyone involved with x86inc should consider dropping REP_RETs altogether.	2 years ago

Mark Reid	716b396740	avfilter/vf_lut3d: add x86-optimized tetrahedral interpolation I spotted an interesting pattern that I didn't see before that leads to the implementation being faster. The bit shifting table I was using before is no longer needed, and was able to remove quite a few lines.

Wu Jianhua	7bbad32d5a	libavfilter/x86/vf_gblur: correct the order of loop step The problem was caused by if the width of the processed block minus 1 is a multiple of the aligned number the instruction jle .bscale_scalar would skip the Optimized Loop Step, which will lead to an incorrect sampling when specifying steps more than 1.

Wu Jianhua	4041c1029b	libavfilter/x86/vf_gblur: add localbuf and ff_horiz_slice_avx2/512() We introduced a ff_horiz_slice_avx2/512() implemented on a new algorithm. In a nutshell, the new algorithm does three things, gathering data from 8/16 rows, blurring data, and scattering data back to the image buffer. Here we used a customized transpose 8x8/16x16 to avoid the huge overhead brought by gather and scatter instructions, which is dependent on the temporary buffer called localbuf added newly.
