2014-12-25	Cleanup: Fix Cycles Apache header.	Thomas Dinges
	This was already mixed a bit, but the dot belongs there.
2014-06-14	Cycles: Add an AVX2 CPU kernel.	Thomas Dinges
	This kernel is compiled with AVX2, FMA3, and BMI compiler flags. At the moment only Intel Haswell benefits from this, but future AMD CPUs will have these instructions as well. Makes rendering on Haswell CPUs a few percent faster, only benchmarked with clang on OS X though. Part of my GSoC 2014.
2014-05-04	Style cleanup: indentation, braces	Campbell Barton

2014-02-25	Fix missing brackets in cpuid bitfield check.	Martijn Berger
	concern raised by lukas_t (rBef73d547cc7c663ad180721094c81b3c81482ac3)
2014-02-25	Fix T38815	Martijn Berger
	For AVX support we need to check both OS support and CPU support.
2014-01-16	Cycles: Add an AVX kernel for CPU rendering.	Thomas Dinges
	* AVX is available on Intel Sandy Bridge and newer and AMD Bulldozer and newer. * We don't use dedicated AVX intrinsics yet, but gcc auto vectorization gives a 3% performance improvement for Caminandes. Tested on an i5-3570, Linux x64. * No change for Windows yet, MSVC 2008 does not support AVX. Reviewed by: brecht Differential Revision: https://developer.blender.org/D216
2013-12-07	Cycles: network render code updated for latest changes and improved	Martijn Berger
	This actually works somewhat now, although viewport rendering is broken and any kind of network error or connection failure will kill Blender. * Experimental WITH_CYCLES_NETWORK cmake option * Networked Device is shown as an option next to CPU and GPU Compute * Various updates to work with the latest Cycles code * Locks and thread safety for RPC calls and tiles * Refactored pointer mapping code * Fix error in CPU brand string retrieval code This includes work by Doug Gale, Martijn Berger and Brecht Van Lommel.

2013-11-22	Cycles: test code for sse 4.1 kernel and alignment for some vector types.	Martijn Berger
	This is mostly work towards enabling the __KERNEL_SSE__ option to start using SIMD operations for vector math operations. This 4.1 kernel performes about 8% faster with that option but overall is still slower than without the option. WITH_CYCLES_OPTIMIZED_KERNEL_SSE41 is the cmake flag for testing this kernel. Alignment of int3, int4, float3, float4 to 16 bytes seems to give a slight 1-2% speedup on tested systems with the current kernel already, so is enabled now.
2013-10-05	Better fix for #36935 and 36316:	Brecht Van Lommel
	* 32 bit GCC builds now have the SSE BVH optimizations turned off, but still compile with SSE flags for better performance. * White color when rendering on Windows seems to have been unrelated to SSE, rather it was a graphics driver not supporting half float textures, added a check for that now.
2013-10-04	Attempt to fix #36935: disable SSE optimizations on 32 bit windows too. ↵	Brecht Van Lommel
	Something strange is going on here, but I don't think it can be fixed before the release, if it is worth at all spending time on this.
2013-10-02	Fix #36316: dots in cycles render on certain CPUs with 32 bit linux builds.	Brecht Van Lommel
	There is some sort of problem with the SSE2 code path, but I couldn't find the cause, maybe a compiler bug due to the large amount of inlining? For now I've disabled SSE2 optimizatons in 32 bit GCC builds.
2013-08-18	Cycles: relicense GNU GPL source code to Apache version 2.0.	Brecht Van Lommel
	More information in this post: http://code.blender.org/ Thanks to all contributes for giving their permission!
2013-06-18	Fix cycles crash on some processors. We actually need S-SSE3 support for this	Brecht Van Lommel
	new BVH traversal code, not just SSE3.
2013-06-04	Fix build error on non-x86 architectures as pointed out by Jochen Schmitt.	Brecht Van Lommel

2013-02-04	Fix cycles intersection issue with overlapping faces on windows 32 bit and CPU	Brecht Van Lommel
	without SSE3 support, due to 80 bit precision float register being used for one bounding box but not the one next to it.
2012-06-09	style cleanup: block comments	Campbell Barton

2012-06-07	style cleanup	Campbell Barton

2011-12-02	Cycles:	Brecht Van Lommel
	* Fix broken compile of test app. * Fix some warnings compiling with gcc for 32 bit. * More tweaks to avoid extended precision issue from #29301.
2011-11-15	Fix #29259: cycles issues on certain processors. Now two versions of the kernel	Brecht Van Lommel
	are compiled, one SSE optimized and the other not, and it will choose between them at runtime.
2011-09-08	Cycles: some warning fixes, cpu device task tweaks, avoid unnecessary	Brecht Van Lommel
	tonemap in non-viewport render, and some utility functions.
2011-09-04	Compile fixes for MinGW, checked with basic initial setup, no CUDA, gcc 4.5.2.	Antony Riakiotakis
	OpenImageIO still gives link-time errors, will try to make a lib for MinGW, see if it is fixed.
2011-05-05	Cycles: two 32 bit fixes with help from IRC user Agiofws.	Brecht Van Lommel
