Cesar Philippidis bd9b3d3d1a [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. (cuOccupancyMaxPotentialBlockSize): Declare. * plugin/cuda-lib.def (cuOccupancyMaxPotentialBlockSize): New CUDA_ONE_CALL_MAYBE_NULL. * plugin/plugin-nvptx.c (CUDA_VERSION < 6050): Define CUoccupancyB2DSize and declare cuOccupancyMaxPotentialBlockSize. (nvptx_exec): Use cuOccupancyMaxPotentialBlockSize to set the default num_gangs and num_workers when the driver supports it.
