Martin Storsjö	9c8bc74c2b	arm: vp9itxfm: Skip empty slices in the first pass of idct_idct 16x16 and 32x32 This work is sponsored by, and copyright, Google. Previously all subpartitions except the eob=1 (DC) case ran with the same runtime: Cortex A7 A8 A9 A53 vp9_inv_dct_dct_16x16_sub16_add_neon: 3188.1 2435.4 2499.0 1969.0 vp9_inv_dct_dct_32x32_sub32_add_neon: 18531.7 16582.3 14207.6 12000.3 By skipping individual 4x16 or 4x32 pixel slices in the first pass, we reduce the runtime of these functions like this: vp9_inv_dct_dct_16x16_sub1_add_neon: 274.6 189.5 211.7 235.8 vp9_inv_dct_dct_16x16_sub2_add_neon: 2064.0 1534.8 1719.4 1248.7 vp9_inv_dct_dct_16x16_sub4_add_neon: 2135.0 1477.2 1736.3 1249.5 vp9_inv_dct_dct_16x16_sub8_add_neon: 2446.7 1828.7 1993.6 1494.7 vp9_inv_dct_dct_16x16_sub12_add_neon: 2832.4 2118.3 2266.5 1735.1 vp9_inv_dct_dct_16x16_sub16_add_neon: 3211.7 2475.3 2523.5 1983.1 vp9_inv_dct_dct_32x32_sub1_add_neon: 756.2 456.7 862.0 553.9 vp9_inv_dct_dct_32x32_sub2_add_neon: 10682.2 8190.4 8539.2 6762.5 vp9_inv_dct_dct_32x32_sub4_add_neon: 10813.5 8014.9 8518.3 6762.8 vp9_inv_dct_dct_32x32_sub8_add_neon: 11859.6 9313.0 9347.4 7514.5 vp9_inv_dct_dct_32x32_sub12_add_neon: 12946.6 10752.4 10192.2 8280.2 vp9_inv_dct_dct_32x32_sub16_add_neon: 14074.6 11946.5 11001.4 9008.6 vp9_inv_dct_dct_32x32_sub20_add_neon: 15269.9 13662.7 11816.1 9762.6 vp9_inv_dct_dct_32x32_sub24_add_neon: 16327.9 14940.1 12626.7 10516.0 vp9_inv_dct_dct_32x32_sub28_add_neon: 17462.7 15776.1 13446.2 11264.7 vp9_inv_dct_dct_32x32_sub32_add_neon: 18575.5 17157.0 14249.3 12015.1 I.e. in general a very minor overhead for the full subpartition case due to the additional loads and cmps, but a significant speedup for the cases when we only need to process a small part of the actual input data. In common VP9 content in a few inspected clips, 70-90% of the non-dc-only 16x16 and 32x32 IDCTs only have nonzero coefficients in the upper left 8x8 or 16x16 subpartitions respectively.

Martin Storsjö	effc1430b2	Revert "checkasm: vp9dsp: Benchmark the dc-only version of idct_idct separately" This reverts commit `81d7f0bbca`. Instead of just benchmarking dc separately, test all relevant subparts (in the next commit). Signed-off-by: Martin Storsjö <martin@martin.st>	8 years ago
Martin Storsjö	81d7f0bbca	checkasm: vp9dsp: Benchmark the dc-only version of idct_idct separately The dc-only mode is already checked to work correctly above, but this allows benchmarking this mode for performance tuning, and allows making sure that it actually is correctly hooked up.

Ronald S. Bultje	0b37cd09a6	checkasm: add vp9dsp.itxfm_add tests. This includes fixes by Henrik Gramner. The forward transforms are derived from the reference encoder. Signed-off-by: Martin Storsjö <martin@martin.st>	8 years ago
Martin Storsjö	2e55e26b40	vp9: Flip the order of arguments in MC functions This makes it match the pattern already used for VP8 MC functions. This also makes the signature match ffmpeg's version of these functions, easing porting of code in both directions. Signed-off-by: Martin Storsjö <martin@martin.st>	8 years ago
Ronald S. Bultje	c935b54bd6	checkasm: add VP9 loopfilter tests. The randomize_buffer() implementation assures that "most of the time", we'll do a good mix of wide16/wide8/hev/regular/no filters for complete code coverage. However, this is not mathematically assured because that would make the code either much more complex, or much less random.
