Nathan E. Egge 8280ec7a32 lavu/riscv: Revert d808070, removing AV_READ_TIME ... The implementation of ff_read_time() for RISC-V uses rdtime which has precision on existing hardware too low (!) for benchmarking purposes. Deleting this implementation falls back on clock_gettime() which was added as the default ff_read_time() implementation in 33e4cc9. Below are metrics gathered on SpacemiT K1, before and after this commit: Before: $ tests/checkasm/checkasm --bench benchmarking with native FFmpeg timers nop: 0.0 checkasm: using random seed 3473665261 checkasm: bench runs 1024 (1 << 10) RVI: - pixblockdsp.get_pixels [OK] - vc1dsp.mspel_pixels [OK] RVF: - audiodsp.audiodsp [OK] checkasm: all 4 tests passed audiodsp.vector_clipf_c: 1388.7 audiodsp.vector_clipf_rvf: 261.5 get_pixels_c: 2.0 get_pixels_rvi: 1.5 vc1dsp.put_vc1_mspel_pixels_tab[0][0]_c: 8.0 vc1dsp.put_vc1_mspel_pixels_tab[0][0]_rvi: 1.0 vc1dsp.put_vc1_mspel_pixels_tab[1][0]_c: 2.0 vc1dsp.put_vc1_mspel_pixels_tab[1][0]_rvi: 0.5 After: $ tests/checkasm/checkasm --bench benchmarking with native FFmpeg timers nop: 56.4 checkasm: using random seed 1021411603 checkasm: bench runs 1024 (1 << 10) RVI: - pixblockdsp.get_pixels [OK] - vc1dsp.mspel_pixels [OK] RVF: - audiodsp.audiodsp [OK] checkasm: all 4 tests passed audiodsp.vector_clipf_c: 23236.4 audiodsp.vector_clipf_rvf: 11038.4 get_pixels_c: 79.6 get_pixels_rvi: 48.4 vc1dsp.put_vc1_mspel_pixels_tab[0][0]_c: 329.6 vc1dsp.put_vc1_mspel_pixels_tab[0][0]_rvi: 38.1 vc1dsp.put_vc1_mspel_pixels_tab[1][0]_c: 89.9 vc1dsp.put_vc1_mspel_pixels_tab[1][0]_rvi: 17.1 Signed-off-by: Rémi Denis-Courmont <remi@remlab.net>		2024-07-31 17:48:50 +03:00
