cudnn kernel documentation void cudnn::detail::dgrad2d_alg1_1

After profiling with nvvp/nvprof, it is hard to decipher what the kernel is exactly doing, is there any documentation which describes each kernel? For example, what does

void cudnn::detail::dgrad2d_alg1_1

do?

I have the same request. If you don’t provide more information about the output of nvprof, why does nvprof provide this functionality???!!!
