2016-07-12Remove bogus dependency from opencl to configmgrStephan Bergmann
Since f41eb66302208f384a475fb20c98b6d1b0676cb6 "opencl: OpenCLZone, detect CL device change and disable CL on crash" vcl links against opencl (so indirectly linked against configmgr), which caused CppunitTest_configmgr_unit to include the configmgr object files both statically (through gb_CppunitTest_use_library_objects) and through the linked-in configmgr dynamic library, which in turn caused ASan builds to report an ODR violation for a doubly defined 'typeinfo name for configmgr::Access'.

2016-07-11opencl: OpenCLZone, detect CL device change and disable CL on crashTomaž Vajngerl
Guard OpenCL calls with OpenCLZone, so if a OpenCL call crashes we detect this and disable OpenCL so next time the user doesn't encounter the crash at the same calculation because he has a broken OpenCL drivers. Similar has been implemented for OpenGL with good results. Additionaly we persistently remember a known good OpenCL device ID and driver version so we can match this and perform calculation tests when they change. This is to ensure that the selected OpenCL device performs as we expect. In this commit the calculation tests aren't included yet. Remove complex static initializer in opencl wrapper library.

2016-04-22opencl: better logging of devices and device selectionTomaž Vajngerl
changes: - Clew misses a lot of things, added defines needed for gathering platform and device info. - Refactored profile saving and loading to use libxml2 instead the weird type of saving the profile data. - Added an additional "log" file which is similar to the OpenGL but it writes the OpenCL relevant information like which devices and platforms are available (+ all the extra useful version information) and which device was selected (if any at all).

2016-04-12Move clew/clew.h into external, tooStephan Bergmann
For consistency with what 38cd1d9a5f00dc69ba0d60e2fe6957090c7a26d1 "clew: move this foreign code to external/clew" did for clew.c. Library_scfilt depends on clew/clew.h, simply make it depend on the full clew external.

2014-12-08Don't treat clew as part of an "external" clcc moduleTor Lillqvist
There is no obvious authoritative upstream for clew anyway, so it causes philosophical problems for distros. For a while, we used to use a zip archive from the "clcc" project on SourceForge that included clew.c and clew.h. (Before that we also just had clew.c and clew.h in our source repo.) So, drop the external/clcc module and have clew.c and clew.h in the source repo again. But this time clew is in a module of its own, not in sc. This re-introduces "No need to have OpenCL optional at configure-time" This reverts commit 764836cb00e8e6dfd2ab48e080a166ec90359e01.

2014-11-27Move more Calc-independent OpenCL stuff from the sc to the opencl moduleTor Lillqvist
No cleanups yet. Just removed the "sc" namespace parts now when this stuff is no longer Calc-specific. There is still horribly confusing use of the same OpenCLDevice name for both a class and as a namespace, for instance. And the OpenCLDevice class has only public static members even, so effectively it acts as just a namespace anyway... Etc. Change-Id: Idc5f30a721df0101426c676f04a85e02c5dc8443
2014-11-27Work in progress: Move Calc-independend OpenCL configuration out of scTor Lillqvist
Intermediate commit. More changes will follow: The device selection logic needs to be moved, too. (And cleaned up.) Instead of the separate formulacalculationoptions dialog we should simply have a normal options page for those OpenCL-related settings that will remain purely Calc-specific, like the formula opcode subsetting.
