2022-07-15	Cycles: generalize shader sorting / locality heuristic to all GPU devices	Brecht Van Lommel
	This was added for Metal, but also gives good results with CUDA and OptiX. Also enable it for future Apple GPUs instead of only M1 and M2, since this has been shown to help across multiple GPUs so the better bet seems to enable rather than disable it. Also moves some of the logic outside of the Metal device code, and always enables the code in the kernel since other devices don't do dynamic compile.

2022-07-14	Cycles: Improve cache usage on Apple GPUs by chunking active indices	Michael Jones
	This patch partitions the active indices into chunks prior to sorting by material in order to tradeoff some material coherence for better locality. On Apple Silicon GPUs (particularly higher end M1-family GPUs), we observe overall render time speedups of up to 15%. The partitioning is implemented by repeating the range of `shader_sort_key` for each partition, and encoding a "locator" key which distributes the indices into sorted chunks.

2022-04-19	Cleanup: Remove unused function in Cycles queue	Sergey Sharybin
	Noticed while looking into oneAPI patch. Seems to be unused, without clear indication why/when it might be needed. Removing the function simplifies adding the new backend. Differential Revision: https://developer.blender.org/D14652
2022-03-07	Cleanup: fix various typos	Brecht Van Lommel

2022-02-11	Cycles: use SPDX license headers	Brecht Van Lommel
	* Replace license text in headers with SPDX identifiers. * Remove specific license info from outdated readme.txt, instead leave details to the source files. * Add list of SPDX license identifiers used, and corresponding license texts. * Update copyright dates while we're at it. Ref D14069, T95597
2022-01-05	Cycles: Add OptiX temporal denoising support	Patrick Mours
	Enables the `bpy.ops.cycles.denoise_animation()` operator again and modifies it to support temporal denoising with OptiX. This requires renders that were done with both the "Vector" and "Denoising Data" passes. Differential Revision: https://developer.blender.org/D11442
2021-11-29	Cycles: Metal readiness: Specify DeviceQueue::enqueue arg types	Michael Jones
	This patch adds new arg-type parameters to `DeviceQueue::enqueue` and its overrides. This is in preparation for the Metal backend which needs this information for correct argument encoding.

2021-10-26	Cycles: remove prefix from source code file names	Brecht Van Lommel
	Remove prefix of filenames that is the same as the folder name. This used to help when #includes were using individual files, but now they are always relative to the cycles root directory and so the prefixes are redundant. For patches and branches, git merge and rebase should be able to detect the renames and move over code to the right file.
