2017-03-21	Cycles: Simplify some extra OpenCL query code	Sergey Sharybin

2017-03-21	Cycles: Cleanup, add some utility functions to shorten access to low level API	Sergey Sharybin
	Should be no functional changes.
2017-03-21	Cycles: Fix wrong vector allocation in the mesh sync code	Lukas Stockner

2017-03-21	Cycles: Fix building of OpenCL kernels	Mai Lavelle
	Theres no overloading of functions in OpenCL so we can't make use of `safe_normalize` with `float2`.
2017-03-20	Fix T50268: Cycles allows to select un supported GPUs for OpenCL	Sergey Sharybin

2017-03-20	Cycles: Update remaining time once per second without waiting for a tile change	Lukas Stockner
	Previously, the code would only update the status string if the main status changed. However, the main status did not include the remaining time, and therefore it wasn't updated until the amount of rendered tiles (which is part of the main status) changed. This commit therefore makes the BlenderSession remember the time of the last status update and forces a status update if the last one was more than a second ago.

2017-03-17	Cycles: Fix mistake in previous split kernel commits	Sergey Sharybin
	Own stupid mistake. Reported by nirved in IRC, thanks!

2017-03-17	Cycles: Fix compilation error of LCG RNG	Sergey Sharybin

2017-03-17	Cycles: Silence strict compiler warning	Sergey Sharybin

2017-03-17	Cycles: Improve memory usage of CPU split kernel by using smaller global size	Mai Lavelle

2017-03-17	Cycles: Fix handling of barriers	Mai Lavelle

2017-03-16	Cycles: Define ccl_local variables in kernel functions	Sergey Sharybin
	Declaring ccl_local in a device function is not supported by certain compilers.
2017-03-16	Cycles: Workaround for compilation error caused by passing KernelGlobals	Sergey Sharybin
	Pass globals as a bare pointer, same as it sued to be prior to split kernel rework. AMD CPU platform and Intel OpenCL were complaining about this. Perhaps we shouldn't pass globals as pointer at all, this isn't something what is really portable and can cause issues on 32 bit perhaps.
2017-03-16	Cycles: Avoid some ccl_local in various kernels	Sergey Sharybin

2017-03-16	Cycles: Adjust global size for OpenCL CPU devices to make them faster	Mai Lavelle

2017-03-15	Cycles: Allow rendering a range of resumable chunks	Sergey Sharybin
	The range is controlled using the following command line arguments: --cycles-resumable-start-chunk --cycles-resumable-end-chunk Those are 1-based index of range for rendering.
2017-03-15	Cycles: Use argument parser for resumable render feature	Sergey Sharybin
	Currently there is no functional changes, but we will be adding couple more of options here soon.
2017-03-14	Cycles: Cleanup, indentation	Sergey Sharybin

2017-03-14	Cycles: Try to avoid infinite loops by catching invalid ray states	Mai Lavelle

2017-03-13	Cycles: Cleanup, wipe obviously outdated parts of split kernel comments	Sergey Sharybin

2017-03-13	fix msvc warnings about unknown opencl pragmas	lazydodo

2017-03-13	Cycles: Add missing header in the file	Sergey Sharybin

2017-03-13	Fixed a bug that caused an additional white diffuse closure call when using	Schoen
	path tracing.
2017-03-13	Fix T50925: Add AO approximation to split kernel	Hristo Gueorguiev

2017-03-13	Cycles: Make MESA compiler more happy	Sergey Sharybin
	While this compiler is not officially supported yet, getting it to work is a nice thing because more and more AMD cards will fall under MESA driver. It's also nice to use explicit comparison with NULL, which makes it more clear whether variable is a boolean or pointer. Even Rust enforces this! Patch by Ian Bruce with own modifications.
2017-03-12	Fix T50628: gray out cycles device menu when no device configured only for ↵	Brecht Van Lommel
	GPU Compute.
2017-03-11	Fix T50888: Numeric overflow in split kernel state buffer size calculation	Mai Lavelle
	Overflow led to the state buffer being too small and the split kernel to get stuck doing nothing forever.
2017-03-11	Fix OpenCL warnings about doubles on some platforms.	Brecht Van Lommel

2017-03-10	Cycles: Cleanup, extra semicolon and space	Sergey Sharybin

2017-03-10	Cycles: Enable SSS and volumes for CUDA and Nvidia OpenCL split kernel	Mai Lavelle

2017-03-09	Cycles: add single program debug option for split kernel	Hristo Gueorguiev
	Single program generally compiles kernels faster (2-3 times), loads faster, takes less drive space (2-3 times), and reduces the number of cached kernels.
2017-03-09	Cycles: split kernel_shadow_blocked to AO & DL parts	Hristo Gueorguiev
	Reduces memory allocation for split kernel. This allows for faster rendering due to bigger global size, specially when GPU memory is limited.

2017-03-09	Cycles: Speedup transparent shadows in split kernel	Hristo Gueorguiev
	This commit enables record-all transparent shadows rays. Perfromance results: R9 290 render time (without synchronization), seconds Before After Change BMW 261.5 262.5 +0.4 % Classroom 869.6 867.3 -0.3 % Fishy Cat 657.4 639.8 -2.7 % Koro 1909.8 692.8 -63.7 % Pabellon Barcelona 1633.3 1238.0 -24.2 % Pabellon Barcelona() 1158.1 903.8 -22.0 % () without glossy connected to volume
2017-03-09	Cycles: SSS and Volume rendering in split kernel	Hristo Gueorguiev
	Decoupled ray marching is not supported yet. Transparent shadows are always enabled for volume rendering. Changes in kernel/bvh and kernel/geom are from Sergey. This simiplifies code significantly, and prepares it for record-all transparent shadow function in split kernel.
2017-03-09	Cycles: Fix CUDA build error for some compilers	Mai Lavelle
	Needed to include `util_types.h` before using `uint`.
2017-03-08	Cycles: Make it more obvious message which initialization failed	Sergey Sharybin

2017-03-08	Cycles: Use 1-based line number for #line directives	Sergey Sharybin
	AMD CPU platform was complaining about #line 0 directives in the code.
2017-03-08	Cycles: Log which device kernels are being loaded for	Sergey Sharybin

2017-03-08	Cycles: Make it possible to access KernelGlobals from split data ↵	Sergey Sharybin
	initialization function
2017-03-08	Cycles: Cleanup, remove residue of previous split kernel data	Sergey Sharybin
	This is all in split data state array.
2017-03-08	Cycles: Fix indentation	Mai Lavelle

2017-03-08	Cycles: Fix strict warning about unused variable	Mai Lavelle

2017-03-08	Cycles: Calculate size of split state buffer kernel side	Mai Lavelle
	By calculating the size of the state buffer in the kernel rather than the host less code is needed and the size actually reflects the requested features. Will also be a little faster in some cases because of larger global work size.
2017-03-08	Cycles: Fix crash after failed kernel build	Mai Lavelle
	Pointers to kernels were uninitialized leading to freeing of random memory addresses. Another reason it would be good to use smart pointers.
2017-03-08	Cycles: Faster building of split kernel	Mai Lavelle
	Simple change to make it so that only kernels that have been modified are rebuilt. Might only be useful during development.
