Function hip_sys::hiprt::hipModuleOccupancyMaxPotentialBlockSizeWithFlags

pub unsafe extern "C" fn hipModuleOccupancyMaxPotentialBlockSizeWithFlags(
    gridSize: *mut i32,
    blockSize: *mut i32,

@brief determine the grid and block sizes to achieves maximum occupancy for a kernel

@param [out] gridSize minimum grid size for maximum potential occupancy @param [out] blockSize block size for maximum potential occupancy @param [in] f kernel function for which occupancy is calulated @param [in] dynSharedMemPerBlk dynamic shared memory usage (in bytes) intended for each block @param [in] blockSizeLimit the maximum block size for the kernel, use 0 for no limit @param [in] flags Extra flags for occupancy calculation (only default supported)

Please note, HIP does not support kernel launch with total work items defined in dimension with size gridDim x blockDim >= 2^32.

@returns hipSuccess, hipInvalidDevice, hipErrorInvalidValue
