2015-05-09Cycles: OpenCL kernel splitGeorge Kyriazis
This commit contains all the work related on the AMD megakernel split work which was mainly done by Varun Sundar, George Kyriazis and Lenny Wang, plus some help from Sergey Sharybin, Martijn Berger, Thomas Dinges and likely someone else which we're forgetting to mention. Currently only AMD cards are enabled for the new split kernel, but it is possible to force split opencl kernel to be used by setting the following environment variable: CYCLES_OPENCL_SPLIT_KERNEL_TEST=1. Not all the features are supported yet, and that being said no motion blur, camera blur, SSS and volumetrics for now. Also transparent shadows are disabled on AMD device because of some compiler bug. This kernel is also only implements regular path tracing and supporting branched one will take a bit. Branched path tracing is exposed to the interface still, which is a bit misleading and will be hidden there soon. More feature will be enabled once they're ported to the split kernel and tested. Neither regular CPU nor CUDA has any difference, they're generating the same exact code, which means no regressions/improvements there. Based on the research paper: https://research.nvidia.com/sites/default/files/publications/laine2013hpg_paper.pdf Here's the documentation: https://docs.google.com/document/d/1LuXW-CV-sVJkQaEGZlMJ86jZ8FmoPfecaMdR-oiWbUY/edit Design discussion of the patch: https://developer.blender.org/T44197 Differential Revision: https://developer.blender.org/D1200
2015-03-27Cycles: Code cleanup, spaces around keywordsSergey Sharybin
This inconsistency drove me totally crazy, it's really confusing when it's inconsistent especially when you work on both Cycles and Blender sides. Shouldn;t cause merge PITA, it's whitespace changes only, Git should be able to merge it nicely.

This was already mixed a bit, but the dot belongs there.

2013-11-18Cycles: 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.
