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
2022-02-11	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 * Remove specific license info from outdated readme.txt, instead leave details to the source files.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
2021-11-30	Cleanup: clang-format, trailing space	Campbell Barton

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.

2021-10-21	Cycles: add shadow path compaction for GPU rendering	Brecht Van Lommel
	Similar to main path compaction that happens before adding work tiles, this compacts shadow paths before launching kernels that may add shadow paths. Only do it when more than 50% of space is wasted. It's not a clear win in all scenes, some are up to 1.5% slower. Likely caused by different order of scheduling kernels having an unpredictable performance impact. Still feels like compaction is just the right thing to avoid cases where a few shadow paths can hold up a lot of main paths. Differential Revision: https://developer.blender.org/D12944
2021-10-21	Cleanup: make HIP and CUDA code more consistent	Brecht Van Lommel
	Ref D12834
2021-10-20	Fix: Add cast to atof for CYCLES_CONCURRENT_STATES_FACTOR env variable parsing.	William Leeson
	The conversion from double to float was causing a build failure. Differential Revision: https://developer.blender.org/D12946
2021-10-20	HIP device code cleanup and fix for high VRAM usage	Sayak Biswas
	This patch cleans up code for HIP device and makes it more consistent with the CUDA code. It also fixes the issue with high VRAM usage on AMD cards using HIP allowing better performance and usage on cards like 6600XT. Added a check in intern/cycles/kernel/bvh/bvh_util.h to prevent compiler error with hipcc Reviewed By: brecht, leesonw Maniphest Tasks: T92124 Differential Revision: https://developer.blender.org/D12834
2021-09-28	Cycles: add HIP device support for AMD GPUs	Brian Savery
	NOTE: this feature is not ready for user testing, and not yet enabled in daily builds. It is being merged now for easier collaboration on development. HIP is a heterogenous compute interface allowing C++ code to be executed on GPUs similar to CUDA. It is intended to bring back AMD GPU rendering support on Windows and Linux. https://github.com/ROCm-Developer-Tools/HIP. As of the time of writing, it should compile and run on Linux with existing HIP compilers and driver runtimes. Publicly available compilers and drivers for Windows will come later. See task T91571 for more details on the current status and work remaining to be done.
