James Almer	a4e4948ffe	x86/cpu: add missing avx2 AVOption in av_parse_cpu_flags() Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Janne Grunau	b7b17ed66e	aarch64: add cpuflags support for NEON and VFP NEON and VFP are currently mandatory for all ARMv8 profiles. Both are handled as extensions as far as cpuflags are concerned. This is consistent with handling x86_64 which always has SSE2, but still handles it as an extension.	11 years ago
Diego Biurrun	8f8bc92365	Add missing #includes for INT64_MAX and INT64_C	11 years ago

Diego Biurrun	b78b10c4b7	avutil: Move internal CPU detection function declarations to private header	11 years ago
Diego Biurrun	f0ce1d9909	cpu: Restructure code to avoid pointless ret variable indirection libavutil/cpu.c:133:9: warning: unused variable ‘ret’ [-Wunused-variable]	12 years ago
Michael Niedermayer	4cf7b87551	av_cpu_count: factorize "detected %d logical cores" message Also print the message just once Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Martin Storsjö	597208fde1	cpu: Include common.h for av_popcount64 This fixes build failures on windows since `2a6eaeaa8`. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Anton Khirnov	2a6eaeaa85	Move get_logical_cpus() from lavc/pthread to lavu/cpu. It will be useful in lavfi, and could conceivably be useful to the user applications as well.	12 years ago
Anton Khirnov	cb45553f57	Remove pointless #undefs of previously forbidden functions.	12 years ago
Michael Niedermayer	7b723ed4c0	cpu: add a few cpu names as aliases for their cpu flags Help to complete this list is welcome! Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	65e57975b9	cpu: add cmov ro the table, which appears to have been forgotten Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	540bd5a95f	av_parse_cpu_caps: add "mmxext" as alias for mmx2 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Diego Biurrun	239fdf1b4a	x86: build: replace mmx2 by mmxext Refactoring mmx2/mmxext YASM code with cpuflags will force renames. So switching to a consistent naming scheme beforehand is sensible. The name "mmxext" is more official and widespread and also the name of the CPU flag, as reported e.g. by the Linux kernel.	13 years ago
Diego Biurrun	65345a5a30	x86: Add CPU flag for the i686 cmov instruction	13 years ago
Michael Niedermayer	eadac34c80	cmdutils/avutil: Move cpu caps parse code into av_parse_cpu_caps() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Mans Rullgard	6eca84bad8	cpu: recognise only cpu flag names pertinent to the architecture Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	3527a73933	avutil: add av_parse_cpu_flags() function This moves the cpu flag parsing code from avconv to avutil so it can be accessed elsewhere. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	d526c5338d	ARM: allow runtime masking of CPU features This allows masking CPU features with the -cpuflags avconv option which is useful for testing different optimisations without rebuilding. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Janne Grunau	363bd1c62c	remove iwmmxt optimizations The were broken since August of 2010 without anyone noticing until three weeks ago. Nobody cares about it anymore and hopefully Marvell will support NEON like in the PXA978 from now on.	13 years ago
Ronald S. Bultje	a9c5b6f602	cpu: initialize mask to -1, so that by default, optimizations are used.	13 years ago
Anton Khirnov	4d851f8dcf	cpu: add av_set_cpu_flags_mask().	13 years ago

Michael Niedermayer	5ad38d93e8	cpudetect: add av_force_cpu_flags() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Justin Ruggles	eba586b0d9	Add a CPU flag for the Atom processor. The Atom has SSSE3 support, which is useful in many cases, but sometimes the SSSE3 version is slower than the SSE2 equivalent on the Atom, but is generally faster on other processors supporting SSSE3. This flag allows for selectively disabling certain SSSE3 functions on the Atom.	14 years ago

Måns Rullgård	9275438a19	Clean up av_get_cpu_flag() Instead of defining functions in per-arch header files included by the main cpu.c, define them normally and call them from the generic one. Originally committed as revision 25084 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	c6c98d0897	Move mm_support() from libavcodec to libavutil, make it a public function and rename it to av_get_cpu_flags(). Originally committed as revision 25076 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
