| * | SSE/MMX/ARM: Fix high frequency noise with unusual number of channels | David Henningsson | 2010-10-13 | 1 | -6/+8 |
| | | | | | | | | | In the assembly optimized versions of SSE, a noise could occur when the number of channels were 3,5,6 or 7. For MMX and ARM, this could occur when the number of channels were 3. Signed-off-by: David Henningsson <david.henningsson@canonical.com> | ||||
| * | cpu: check for CMOV flag before using this intsruction in assembly | Lennart Poettering | 2010-02-09 | 1 | -1/+1 |

| * | svolume: fix MMX error | Wim Taymans | 2009-10-30 | 1 | -1/+6 |
| | | | | | | We need to sign extend the lower part of the multiplication before adding it to the higher part. Makes -1 * 0xffff work again. | ||||
| * | simd: update test cases | Lennart Poettering | 2009-10-29 | 1 | -0/+4 |

| * | Fix build when using -fweb, accept both register and memory constraints. | Diego Elio 'Flameeyes' Pettenò | 2009-10-07 | 1 | -2/+2 |
| | | | | | | This was reported as Gentoo bug #287391 by Torsten Kaiser, and the fix was suggested by Mike Frysinger. | ||||
| * | svolume: tweak constraints for 32 bits | Wim Taymans | 2009-09-23 | 1 | -2/+2 |
| | | | | | | | Tweak the constraints a little so that register starved 32bit systems can select a stack variable for the channel paramter instead of reusing one of the registers we're using in the code. | ||||
| * | svolume_mmx: disable test accidentaly left on | Lennart Poettering | 2009-09-17 | 1 | -1/+1 |
| | | |||||
| * | svolume_mmx: optimize some more | Wim Taymans | 2009-09-16 | 1 | -13/+7 |
| | | | | | | | We can reorder the algortihm a bit like we do for sse so that we don't need the contants and masking instructions. Saves 2 instructions for the mmx code. | ||||
| * | simd: be more precise which SIMD optimizations we activate | Lennart Poettering | 2009-09-09 | 1 | -3/+6 |
| | | |||||
| * | svolume: cleanups | Wim Taymans | 2009-08-20 | 1 | -9/+9 |
| | | | | | | Use PA_MAX Use pa_rtclock_now() for benchmarks | ||||
| * | whitespace fixes | Wim Taymans | 2009-08-20 | 1 | -183/+183 |
| | | |||||
| * | svolume: fix compilation in 32bits | Wim Taymans | 2009-08-20 | 1 | -6/+6 |
| | | |||||
| * | svolume: add CPU guards around code | Wim Taymans | 2009-08-20 | 1 | -0/+6 |
| | | | | | Mark code that should only be compiled on x86 CPUs with proper defines. | ||||
| * | svolume: remove unneeded compare | Wim Taymans | 2009-08-20 | 1 | -1/+0 |
| | | | | | | We don't need the compare because the sub operation already set the right flags for us. | ||||
| * | volume: remove ref functions | Wim Taymans | 2009-08-20 | 1 | -223/+0 |
| | | |||||
| * | volume: improved comments | Wim Taymans | 2009-08-20 | 1 | -6/+6 |
| | | |||||
| * | volume: make the benchmark more meaningfull | Wim Taymans | 2009-08-20 | 1 | -20/+33 |
| | | | | | MMX is about 6x faster, SSE around 15x on my machine. | ||||
| * | svolume: add some comments | Wim Taymans | 2009-08-20 | 1 | -0/+18 |
| | | |||||
| * | main: hook up cpu detection code | Wim Taymans | 2009-08-20 | 1 | -8/+10 |
| | | | | | | | Add CPU detection code to activate the various optimisations. Move some method definitions around. Use compatibility macros when we can. | ||||
| * | svolume: improve SSE and MMX code | Wim Taymans | 2009-08-20 | 1 | -66/+134 |
| | | |||||
| * | volume_mmx: fix mmx code a bit | Wim Taymans | 2009-08-20 | 1 | -20/+26 |
| | | |||||
| * | volume: add first mmx optimized function | Wim Taymans | 2009-08-20 | 1 | -0/+424 |
| Add code for an mmx optimized version of s16ne volume scaling. Install the custom function. | |||||
