Cycles: Add support for rendering on Intel GPUs using oneAPI This patch adds a new Cycles device with similar functionality to the existing GPU devices. Kernel compilation and runtime interaction happen via oneAPI DPC++ compiler and SYCL API. This implementation is primarly focusing on Intel® Arc™ GPUs and other future Intel GPUs. The first supported drivers are 101.1660 on Windows and 22.10.22597 on Linux. The necessary tools for compilation are: - A SYCL compiler such as oneAPI DPC++ compiler or https://github.com/intel/llvm - Intel® oneAPI Level Zero which is used for low level device queries: https://github.com/oneapi-src/level-zero - To optionally generate prebuilt graphics binaries: Intel® Graphics Compiler All are included in Linux precompiled libraries on svn: https://svn.blender.org/svnroot/bf-blender/trunk/lib The same goes for Windows precompiled binaries but for the graphics compiler, available as "Intel® Graphics Offline Compiler for OpenCL™ Code" from https://www.intel.com/content/www/us/en/developer/articles/tool/oneapi-standalone-components.html, for which path can be set as OCLOC_INSTALL_DIR. Being based on the open SYCL standard, this implementation could also be extended to run on other compatible non-Intel hardware in the future.

Cycles: oneAPI: Optimize texture access by using GPU HW sampler The current usage of software-based texture operations in the oneAPI implementation puts additional register pressure on the GPU compiler during register allocation. And it also creates code that requires maintenance. This commit is intended to address this situation by utilizing a recently productized SYCL bindless texture API to enable HW-based texture operations using Intel GPUs' hardware sampler. This currently translates to 1-11% rendering speedups (scene-specific) on my Arc A770 and Arc B580. At the moment, there are small performance regressions with NanoVDB texture operations on Arc B580 and small performance regressions in shade surface MNEE and Raytrace kernels on Arc A770, but they look recoverable and will be handled in the future.
