2016-01-04	Remove SCons building system	Sergey Sharybin
	While SCons building system was serving us really good for ages it's no longer having much attention by the developers and started to become quite a difficult task to maintain. What's even worse -- there started to be quite serious divergence between SCons and CMake which was only accumulating over the releases now. The fact that none of the active developers are really using SCons and that our main studio is also using CMake spotting bugs in the SCons builds became quite a difficult task and we aren't always spotting them in time. Meanwhile CMake became really mature building system which is available on every platform we support and arguably it's also easier and more robust to use. This commit includes: - Removal of actual SCons building system - Removal of SCons git submodule - Removal of documentation which is stored in the sources and covers SCons - Tweaks to the buildbot master to stop using SCons submodule (this change requires deploying to the server) - Tweaks to the install dependencies script to skip installing or mentioning SCons building system - Tweaks to various helper scripts to avoid mention of SCons folders/files as well Reviewers: mont29, dingto, dfelinto, lukastoenne, lukasstockner97, brecht, Severin, merwin, aligorith, psy-fi, campbellbarton, juicyfruit Reviewed By: campbellbarton, juicyfruit Differential Revision: https://developer.blender.org/D1680
2015-05-22	Cycles: Restructure kernel files organization	Sergey Sharybin
	Since the kernel split work we're now having quite a few of new files, majority of which are related on the kernel entry points. Keeping those files in the root kernel folder will eventually make it really hard to follow which files are actual implementation of Cycles kernel. Those files are now moved to kernel/kernels/<device_type>. This way adding extra entry points will be less noisy. It is also nice to have all device-specific files grouped together. Another change is in the way how split kernel invokes logic. Previously all the logic was implemented directly in the .cl files, which makes it a bit tricky to re-use the logic across other devices. Since we'll likely be looking into doing same split work for CUDA devices eventually it makes sense to move logic from .cl files to header files. Those files are stored in kernel/split. This does not mean the header files will not give error messages when tried to be included from other devices and their arguments will likely be changed, but having such separation is a good start anyway. There should be no functional changes. Reviewers: juicyfruit, dingto Differential Revision: https://developer.blender.org/D1314

2014-12-31	Cycles: Post-reintegration tweaks to ensure things do compile	Sergey Sharybin
	This commit contains all the tweaks which were missing in initial patch re-integration from the standalone Cycles repository. This commit also contains an utility cmake macro to help linking targets with different libraries for release/debug builds, the name currently is target_link_libraries_decoupled it gets a target and list of libraries and makes sure debug builds are using libraries with "_d" suffix. After all this changes it'll hopefully be easier to interchange patches between blender and standalone repositories, because they're now quite identical.
2014-12-31	Cycles: Be ready for gflags namespace auto-detect	Sergey Sharybin
	This way it is now possible to use gflags >= 2.1, where all the functions were moved from google to gflags namespace. This isn't currently used in blender, but for standalone repository this change is essential.

	CPU rendering is allowed to allocate memory from multiple threads, which means statistics need to be avare of this.

2014-10-04	Cycles: Add support for debug passes	Sergey Sharybin
	Currently only summed number of traversal steps and intersections used by the camera ray intersection pass is implemented, but in the future we will support more debug passes which would help checking what things makes the scene slow. Example of such extra passes could be number of bounces, time spent on the shader tree evaluation and so. Implementation from the Cycles side is pretty much straightforward, could only mention here that it's a build-time option disabled by default. From the blender side it's implemented as a PASS_DEBUG with several subtypes possible. This way we don't need to create an extra DNA pass type for each of the debug passes, saving us a bits.

2014-08-05	Deduplicate CUDA and OpenCL wranglers	Sergey Sharybin
	For now it was mainly about OpenCL wrangler being duplicated between Cycles and Compositor, but with OpenSubdiv work those wranglers were gonna to be duplicated just once again. This commit makes it so Cycles and Compositor uses wranglers from this repositories: - https://github.com/CudaWrangler/cuew - https://github.com/OpenCLWrangler/clew This repositories are based on the wranglers we used before and they'll be likely continued maintaining by us plus some more players in the market. Pretty much straightforward change with some tricks in the CMake/SCons to make this libs being passed to the linker after all other libraries in order to make OpenSubdiv linked against those wranglers in the future. For those who're worrying about Cycles being less standalone, it's not truth, it's rather more flexible now and in the future different wranglers might be used in Cycles. For now it'll just mean those libs would need to be put into Cycles repository together with some other libs from Blender such as mikkspace. This is mainly platform maintenance commit, should not be any changes to the user space.

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.

2014-01-07	Added scons option to actually build the sse41 kernel. CMake already has it	Martijn Berger

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.

Ended up with such decision after discussion with Brecht. The thing is, if we'll support runtime compilation on windows we'll end up having lots of reports about different aspects of something doesn't work (you need particular toolkit version, msvc installed, environment variables set properly and so) and giving feedback on such reports will waste time.

2012-11-15	OSL Scons rules	Sergey Sharybin
	Initial support of OSL builds using SCons build system. Only tested on Linux now. No changes to configuration files themselves -- for now check how it's configured for linux buildbot (it was already horror to make all this changes and verify them, changes to linux-config.py could easily be done later). Currently WITH_BF_STATICOSL and WITH_BF_STATICLLVM are more like rudiments because linking against oslexec requires special trick with --whole-archive. We woul either need to find a way dealing with this oslexec less hackish or drop STATICOSL and STATICLLVM flags. Will keep dropping this flags for until we have "final" build rules for OSL. Still can not make 32bit linux rendering with OSL -- blender simply crashes when starting rendering. So for time being this issues are solving disabled OSL for 32bit build slaves.
