2022-04-04Cleanup: ensure space after file named in headersCampbell Barton
Add blank lines after file references to avoid them being interpreted as doc-strings the following declarations.
2022-02-11File headers: SPDX License migrationCampbell Barton
Use a shorter/simpler license convention, stops the header taking so much space. Follow the SPDX license specification: https://spdx.org/licenses - C/C++/objc/objc++ - Python - Shell Scripts - CMake, GNUmakefile While most of the source tree has been included - `./extern/` was left out. - `./intern/cycles` & `./intern/atomic` are also excluded because they use different header conventions. doc/license/SPDX-license-identifiers.txt has been added to list SPDX all used identifiers. See P2788 for the script that automated these edits. Reviewed By: brecht, mont29, sergey Ref D14069
2020-09-07GPUExtensions: GL backend isolationClément Foucault
This is part of the Vulkan task T68990. This commits changes a few things: - Rename extensions to capabilities (but left the file name untouched). - Cubemap mip render workaround detection is rewritten using gl commands to avoid using the GPU API before initialization. - Put all the capabilities that are only relevant for the GL backend inside GLContext as static variables. - Cleanup the names of the limit variables. - Separate all GL related workaround search inside the GL module.
2020-09-07GPUPlatform: GL backend isolationClément Foucault
Part of the vulkan implementation T68990. Pretty straight forward. Just move the GL code inside the GLBackend and make the GPUPlatformGlobal a class object.
2020-09-01GPUDebug: Reformat GL debug callbacks and move them to GL backendClément Foucault
Now the callbacks are setup for each debug context. The formating has been reworked to be less verbose and make errors and warnings stand out from the notifications. Errors are most of the time sufficiently explicit in their message. This also remove the support for AMD_debug_output which is 10 years old. This is related to the Vulkan port T68990.

2020-08-07Code Style: use "#pragma once" in source directoryJacques Lucke
This replaces header include guards with `#pragma once`. A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`), because they are used in other places. This patch has been generated by P1561 followed by `make format`. Differential Revision: https://developer.blender.org/D8466

2019-10-04GPU: Platform Support LevelJeroen Bakker
Adds a check when starting blender if your platform is supported. We use a blacklist as drivers are updated more regular then blender (stable releases). The mechanism detects if the support level changed or has been validated by the user previously. Changes can happen due to users updating their drivers, but also when we change the support level in our code base. When the user has seen the limited support level message it is saved in the user config. It would be better to have a system specific config section, but currently not clear what could benefit from that. When the platform is unsupported or has limited support a dialog box will appear including a link to our user manual describing what to do. **Windows** Windows uses the MessageBox that is provided by the windows kernel. **X11** We use a very lowlevel messagebox for X11. It is very limited in use and can be fine tuned when needed. **SDL/APPLE** There is no implementation for SDL or APPLE at this moment as the platform support feature targets mostly Windows users.

2019-09-29Sculpt: multithread GPU draw buffer filling for workbenchBrecht Van Lommel
This improves performance of some sculpt tools, particularly those that modify many vertices like filter and mask tools, or use brushes with large radius. For mask expand it can make updates up to 2x faster on heavy meshes, but for most tools it's more on the order of 1-1.1x. There are bigger bottlenecks to solve, like normal updates.

2019-02-18doxygen: add newline after \fileCampbell Barton
While \file doesn't need an argument, it can't have another doxy command after it.
2019-02-06Cleanup: remove redundant doxygen \file argumentCampbell Barton
Move \ingroup onto same line to be more compact and make it clear the file is in the group.
2019-02-01Cleanup: remove redundant, invalid info from headersCampbell Barton
BF-admins agree to remove header information that isn't useful, to reduce noise. - BEGIN/END license blocks Developers should add non license comments as separate comment blocks. No need for separator text. - Contributors This is often invalid, outdated or misleading especially when splitting files. It's more useful to git-blame to find out who has developed the code. See P901 for script to perform these edits.
2018-07-19GPU: Add GC to FBOs and UBOs and centralize all GCsClément Foucault
GPUFrameBuffers were being free when no context was attached or in the wrong gl context. This make sure this does not happen again. You can now safely free any gl resource from any thread (well as long as it's not used anymore!).

2015-07-02Make OpenGL debug contexts a flag --debug-gpu instead of a compile timeAntony Riakiotakis
option. This makes sense, since contexts get created at runtime, there is little reason to require recompilation for this. Only works on linux currently, will be doing more OSs later

2015-02-23Debug GPU functionality from soc-viewport_fx by Jason WilkinsAntony Riakiotakis
patch number D706 with changes: - WITH_GPU_DEBUG just creates a debug context (and enables the debug messaging system functions) but leaves the checks we had intact. Old patch added the debug functionality only if we had the flag on to save some performance. Rationale here is that we might not want to recompile blender just to get the extra information, and having users start blender with a -d flag to get the extra information is also useful for bug reports. Those checks already existed and most expensive ones are hidden behind a debug mode check so performance should not be that bad. - Did some cleanup of existing functionality: When things go wrong blender side, just print the error, don't check for GL errors first. - Did not port changes needed for GLES to regular glew.h - Got rid of duplicate or very similar new functionality. Generally, code is more moving things around/cleanup and should work exactly as before apart from the debug context, so it's safe to add even now. It also provides a nice substitute function for glu error descriptions
