* avcodec/vc1: Arm 32-bit NEON deblocking filter fast pathsBen Avison2022-04-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | checkasm benchmarks on 1.5 GHz Cortex-A72 are as follows. Note that the C version can still outperform the NEON version in specific cases. The balance between different code paths is stream-dependent, but in practice the best case happens about 5% of the time, the worst case happens about 40% of the time, and the complexity of the remaining cases fall somewhere in between. Therefore, taking the average of the best and worst case timings is probably a conservative estimate of the degree by which the NEON code improves performance. vc1dsp.vc1_h_loop_filter4_bestcase_c: 19.0 vc1dsp.vc1_h_loop_filter4_bestcase_neon: 48.5 vc1dsp.vc1_h_loop_filter4_worstcase_c: 144.7 vc1dsp.vc1_h_loop_filter4_worstcase_neon: 76.2 vc1dsp.vc1_h_loop_filter8_bestcase_c: 41.0 vc1dsp.vc1_h_loop_filter8_bestcase_neon: 75.0 vc1dsp.vc1_h_loop_filter8_worstcase_c: 294.0 vc1dsp.vc1_h_loop_filter8_worstcase_neon: 102.7 vc1dsp.vc1_h_loop_filter16_bestcase_c: 54.7 vc1dsp.vc1_h_loop_filter16_bestcase_neon: 130.0 vc1dsp.vc1_h_loop_filter16_worstcase_c: 569.7 vc1dsp.vc1_h_loop_filter16_worstcase_neon: 186.7 vc1dsp.vc1_v_loop_filter4_bestcase_c: 20.2 vc1dsp.vc1_v_loop_filter4_bestcase_neon: 47.2 vc1dsp.vc1_v_loop_filter4_worstcase_c: 164.2 vc1dsp.vc1_v_loop_filter4_worstcase_neon: 68.5 vc1dsp.vc1_v_loop_filter8_bestcase_c: 43.5 vc1dsp.vc1_v_loop_filter8_bestcase_neon: 55.2 vc1dsp.vc1_v_loop_filter8_worstcase_c: 316.2 vc1dsp.vc1_v_loop_filter8_worstcase_neon: 72.7 vc1dsp.vc1_v_loop_filter16_bestcase_c: 62.2 vc1dsp.vc1_v_loop_filter16_bestcase_neon: 103.7 vc1dsp.vc1_v_loop_filter16_worstcase_c: 646.5 vc1dsp.vc1_v_loop_filter16_worstcase_neon: 110.7 Signed-off-by: Ben Avison <bavison@riscosopen.org> Signed-off-by: Martin Storsjö <martin@martin.st>

| | | | | | | | This reverts commit 2589060b92eeeb944c6e2b50e38412c0c5fabcf4 which was originally to fix the FATE test. The real cause of the test breakage was fixed in 22b7c37275c611b5417722d8941844028aed7f25. Signed-off-by: J. Dekker <jdek@itanimul.li>
* lavc/arm: dont assign hevc_qpel functions for non-multiple of 8 widthsJ. Dekker2022-01-04
| | | | | | | | | | | The assembly is written assuming that the width is a multiple of 8. However the real issue is the functions were errorneously assigned to the 2, 4, 6 & 12 widths. This behaviour never broke the decoder as samples which trigger the functions for these widths have not been found in the wild. This relies on the mappings in ff_hevc_pel_weight[]. Signed-off-by: J.

* arm: hevc_qpel: Fix the assembly to work with non-multiple of 8 widthsMartin Storsjö2021-08-25
| | | | | | | | | | | | | | | | | | | | This unbreaks the fate-checkasm-hevc_pel test on arm targets. The assembly assumed that the width passed to the DSP functions is a multiple of 8, while the checkasm test used other widths too. This wasn't noticed before, because the hevc_pel checkasm tests (that were added in 9c513edb7999a35ddcc6e3a8d984a96c8fb492a3 in January) weren't run as part of fate until in b492cacffd36ad4cb251ba1f13ac398318ee639a in August. As this hasn't been an issue in practice with actual full decoding tests, it seems like the actual decoder doesn't call these functions with such widths. Therefore, we could alternatively fix the test to only test things that the real decoder does, and this modification could be reverted. Signed-off-by: Martin Storsjö <martin@martin.st>

This allows the loaded address to be passed to a BLX instruction and the correct mode change will occur. See: https://sourceware.org/bugzilla/show_bug.cgi?id=21458 By using adr with a label that isn't annotated as a thumb function, we avoid the new behaviour in binutils 2.29 and get the same behaviour as in prior releases, and as in other assemblers (ms armasm.exe, clang's built in assembler) - an idea that Janne Grunau came up with.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | clang now (in the upcoming 5.0 version) is capable of building our arm assembly without relying on gas-preprocessor, although clang/LLVM doesn't support .dn register aliases. The VC1 MC assembly was only built and used if the chosen assembler supported the .dn directives though. This was supported as long as gas-preprocessor was used. This means that VC1 decoding got a speed regression on clang 5.0, unless the user manually chose using gas-preprocessor again. By avoiding using the .dn register aliases, we can build the VC1 MC assembly with the latest clang version. Support for the .dn/.qn directives in clang/LLVM isn't actively planned, see https://bugs.llvm.org/show_bug.cgi?id=18199. This partially reverts 896a5bff64264f4d01ed98eacc97a67260c1e17e.
