Kieran Kunhya	865b70bc5d	Add AVX2 capable CPU detection. Patch based on x264's AVX2 detection Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Kieran Kunhya	4d6ee07255	libavutil: x86: Add AVX2 capable CPU detection. Patch based on x264's AVX2 detection Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Diego Biurrun	80fefbed62	x86: cpu: Restore some explanatory comments removed in `7160bb7`	11 years ago
Diego Biurrun	b78b10c4b7	avutil: Move internal CPU detection function declarations to private header	11 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
Janne Grunau	8f5587c3d0	cpu.h: define AV_CPU_FLAG_MMX2 for libavutil major 52	12 years ago
Michael Niedermayer	64604e2679	cpu: improve av_get_cpu_flags() doxy Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	4b529edff8	deprecate av_parse_cpu_flags This function is problematic in several ways, its also quite unpredictable which flags it ends up turning on Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 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.	12 years ago
Michael Niedermayer	eeddd3962e	cpu.h: include version.h for LIBAVUTIL_VERSION_MAJOR Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Diego Biurrun	65345a5a30	x86: Add CPU flag for the i686 cmov instruction	13 years ago
Michael Niedermayer	5e1286a72f	libavutil: Document the shortcommings of av_parse_cpu_flags() and suggest that av_parse_cpu_caps() be used. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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	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
Michael Niedermayer	f64cfba93b	libavutil: document av_force_cpu_flags(-1). Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	4d851f8dcf	cpu: add av_set_cpu_flags_mask().	13 years ago
Reimar Döffinger	b223035511	Detect and check for CMOV. Some MMX-only CPUs do not have support for CMOV. All SSE/MMX2 CPUs should be fine, thus no check was added to those functions. See also https://sourceforge.net/tracker/?func=detail&aid=3358347&group_id=205275&atid=992986 Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Jason Garrett-Glaser	96a59cf37b	x86: XOP/FMA4 CPU detection support	13 years ago
Michael Niedermayer	5ad38d93e8	cpudetect: add av_force_cpu_flags() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Diego Biurrun	153382e1b6	multiple inclusion guard cleanup Add missing multiple inclusion guards; clean up #endif comments; add missing library prefixes; keep guard names consistent.	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
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	cdeba2de82	x86: check for AVX support This adds configure and runtime checks for AVX support on x86 CPUs. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit `87f1355f9b`)	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	14 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	14 years ago
Stefano Sabatini	e778e50f63	Sort AV_CPU_FLAG* by value. Originally committed as revision 25047 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	d593b4ed02	Fix typo. Originally committed as revision 25046 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	7160bb716b	Rename FF_MM_ symbols related to CPU features flags as AV_CPU_FLAG_ symbols, and move them from libavcodec/avcodec.h to libavutil/cpu.h. Originally committed as revision 25040 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
