2021-10-18	Cycles: replace integrator state argument macros	Brecht Van Lommel
	* Rename struct KernelGlobals to struct KernelGlobalsCPU * Add KernelGlobals, IntegratorState and ConstIntegratorState typedefs that every device can define in its own way. * Remove INTEGRATOR_STATE_ARGS and INTEGRATOR_STATE_PASS macros and replace with these new typedefs. * Add explicit state argument to INTEGRATOR_STATE and similar macros In preparation for decoupling main and shadow paths.

2021-10-14	Cycles: Kernel address space changes for MSL	Michael Jones
	This is the first of a sequence of changes to support compiling Cycles kernels as MSL (Metal Shading Language) in preparation for a Metal GPU device implementation. MSL requires that all pointer types be declared with explicit address space attributes (device, thread, etc...). There is already precedent for this with Cycles' address space macros (ccl_global, ccl_private, etc...), therefore the first step of MSL-enablement is to apply these consistently. Line-for-line this represents the largest change required to enable MSL. Applying this change first will simplify future patches as well as offering the emergent benefit of enhanced descriptiveness. The vast majority of deltas in this patch fall into one of two cases: - Ensuring ccl_private is specified for thread-local pointer types - Ensuring ccl_global is specified for device-wide pointer types Additionally, the ccl_addr_space qualifier can be removed. Prior to Cycles X, ccl_addr_space was used as a context-dependent address space qualifier, but now it is either redundant (e.g. in struct typedefs), or can be replaced by ccl_global in the case of pointer types. Associated function variants (e.g. lcg_step_float_addrspace) are also redundant. In cases where address space qualifiers are chained with "const", this patch places the address space qualifier first. The rationale for this is that the choice of address space is likely to have the greater impact on runtime performance and overall architecture. The final part of this patch is the addition of a metal/compat.h header. This is partially complete and will be extended in future patches, paving the way for the full Metal implementation.

2021-09-21	Cycles: merge of cycles-x branch, a major update to the renderer	Brecht Van Lommel
	This includes much improved GPU rendering performance, viewport interactivity, new shadow catcher, revamped sampling settings, subsurface scattering anisotropy, new GPU volume sampling, improved PMJ sampling pattern, and more. Some features have also been removed or changed, breaking backwards compatibility. Including the removal of the OpenCL backend, for which alternatives are under development. Release notes and code docs: https://wiki.blender.org/wiki/Reference/Release_Notes/3.0/Cycles https://wiki.blender.org/wiki/Source/Render/Cycles Credits: * Sergey Sharybin * Brecht Van Lommel * Patrick Mours (OptiX backend) * Christophe Hery (subsurface scattering anisotropy) * William Leeson (PMJ sampling pattern) * Alaska (various fixes and tweaks) * Thomas Dinges (various fixes) For the full commit history, see the cycles-x branch. This squashes together all the changes since intermediate changes would often fail building or tests. Ref T87839, T87837, T87836 Fixes T90734, T89353, T80267, T80267, T77185, T69800
2019-08-26	Cycles: inline more functions on the GPU	Patrick Mours
	This makes little difference for CUDA and OpenCL, but will be helpful for Optix.
2019-08-26	Cycles: change svm node decoding for more efficient code generation on GPU	Patrick Mours
	These functions no longer accept NULL. They were renamed for clarity and to avoid hidden merge issues. Ref D5363

	Uninitialized variables are harder to handle for the compiler. Ref D5363

	Looks like some weird compiler difference with signed vs unsigned ints.
2016-10-30	Cycles: Fix OpenCL compilation with the new brick texture	Lukas Stockner

2016-10-30	Cycles: Add smoothing option to the Brick Texture	Lukas Stockner
	This option allows to create a smoother transition between Bricks and Mortar - 0 applies no smoothing, and 1 smooths across the whole mortar width. Mainly useful for displacement textures. The new default value for the smoothing option is 0.1 to give some smoothing that helps with antialiasing, but existing nodes are loaded with smoothing 0 to preserve compatibility.

2015-09-18	Fix T46030: Strange behavior of Cycles Brick Texture	Sergey Sharybin
	Added some extra seed to the hash, so it's now less likely to give repetitive patters at values around zero. This will change distribution of bricks for existing files. but it's something inevitable.
2015-04-27	Cycles: Use native saturate function for CUDA	Sergey Sharybin
	This more a workaround for CUDA optimizer which can't optimize clamp(x, 0, 1) into a single instruction and uses 4 instructions instead. Original patch by @lockal with own modification: Don't make changes outside of the kernel. They don't make any difference anyway and term saturate() has a bit different meaning outside of kernel. This gives around 2% of speedup in Barcelona file, but in more complex shader setups with lots of math nodes with clamping speedup could be much nicer.

2013-11-18	Cycles: change __device and similar qualifiers to ccl_device in kernel code.	Brecht Van Lommel
	This to avoids build conflicts with libc++ on FreeBSD, these __ prefixed values are reserved for compilers. I apologize to anyone who has patches or branches and has to go through the pain of merging this change, it may be easiest to do these same replacements in your code and then apply/merge the patch.
