[libgomp, nvptx] Allow cuGetErrorString to be NULL Cuda driver api function cuGetErrorString is available in version 6.0 and higher. Currently, when the driver that is used does not contain this function, the libgomp nvptx plugin will not build (PLUGIN_NVPTX_DYNAMIC == 0) or run (PLUGIN_NVPTX_DYNAMIC == 1). This patch fixes this problem by testing for the presence of the function, and handling absence. Build on x86_64 with nvptx accelerator and reg-tested libgomp, both with and without --without-cuda-driver. 2018-08-08 Tom de Vries <tdevries@suse.de> * plugin/cuda-lib.def (cuGetErrorString): Use CUDA_ONE_CALL_MAYBE_NULL. * plugin/plugin-nvptx.c (cuda_error): Handle if cuGetErrorString is not present.

[libgomp, nvptx] Fall back to cuLinkAddData/cuLinkCreate if _v2 not found Cuda driver api functions cuLinkAddData and cuLinkCreate are available starting version 5.5. In version 6.5, they are remapped onto _v2 versions. The dlopen interface of the libgomp nvptx plugin uses the _v2 versions, so it won't work with a cuda driver with driver api version lower than 6.5. This patch fixes the problem by testing for the presence of the _v2 versions, and falling back to the original versions in case of absence of the _v2 versions. Build on x86_64 with nvptx accelerator and reg-tested libgomp, both with and without --without-cuda-driver. 2018-08-08 Tom de Vries <tdevries@suse.de> * plugin/cuda-lib.def (cuLinkAddData_v2, cuLinkCreate_v2): Declare using CUDA_ONE_CALL_MAYBE_NULL. * plugin/plugin-nvptx.c (cuLinkAddData, cuLinkCreate): Undef and declare.

[nvptx] Use CUDA driver API to select default runtime launch geometry The CUDA driver API starting version 6.5 offers a set of runtime functions to calculate several occupancy-related measures, as a replacement for the occupancy calculator spreadsheet. This patch adds a heuristic for default runtime launch geometry, based on the new runtime function cuOccupancyMaxPotentialBlockSize. Build on x86_64 with nvptx accelerator and ran libgomp testsuite. 2018-08-13 Cesar Philippidis <cesar@codesourcery.com> Tom de Vries <tdevries@suse.de> PR target/85590 * plugin/cuda/cuda.h (CUoccupancyB2DSize): New typedef.
