* lavu: Set default FF_TIMER_UNITS to "ns"Nathan E. Egge2024-08-051-0/+1

* lavu/riscv: Revert d808070, removing AV_READ_TIMENathan E. Egge2024-07-311-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* lavu/riscv: AV_READ_TIME cycle counterRémi Denis-Courmont2022-09-131-0/+2
| | | | | | | | | | | This uses the architected RISC-V 64-bit cycle counter from the RISC-V unprivileged instruction set. In 64-bit and 128-bit, this is a straightforward CSR read. In 32-bit mode, the 64-bit value is exposed as two CSRs, which cannot be read atomically, so a loop is necessary to detect and fix up the race condition where the bottom half wraps exactly between the two reads.
* avutil/log: Don't include avutil.hAndreas Rheinhardt2022-02-241-0/+1
| | | | | | | | | | | | It has been included since af5f434f8c0fb3b4ee3b206ebc1946ca660a8abe for deprecation reasons, but removing it has been forgotten after it had served is purpose. So remove it. For convenience, include version.h instead as LIBAVUTIL_VERSION_INT is supposed to be used when creating AVClasses.

* | lavu/timer.h: add Linux Perf API supportClément Bœsch2017-09-081-3/+43
| | | | | | | | | | | | | | | | | | | | | | | | Refer to "checkasm: use perf API on Linux ARM*" commit for the rationale. The implementation is somehow duplicated with checkasm, but so is the current usage of AV_READ_TIME(). Until these implementations and heuristics are made consistent, I don't see a way of sharing that code. Note: when using libavutil/timer.h, it is now important to include before any other include due to the _GNU_SOURCE requirement.

| | | | | | | | | | | | | | | | | | | | Not guaranteed to be in nanosecond resolution. On iOS 7 the duration of one tick is 125/3 ns which is still more than an order of magnitude better then microseconds. Replace decicycles with the neutral UNITS. Decicycles is strange but tenths of a nanosecond and unspecific "deci"-ticks for mach_absolute_time is just silly.
