[QST] does cutlass depthwise conv support 1x1 filter

[tengdecheng]

hi, i have a question about depthwise conv with params like 1x1 filter, stride=1, pad=0, dilation=1, i have a compile error raise by checking kWarpGemmIterations in cutlass/conv/threadblock/depthwise_mma_base.h:

template <
    /// Size of the Gemm problem - concept: gemm::GemmShape<>
    typename Shape_,
    /// Policy describing tuning details (concept: MmaPolicy)
    typename Policy_,
    /// Number of stages,
    int Stages,
    /// Used for partial specialization
    typename Enable = bool>
class DepthwiseDirectConvMmaBase {
    using Policy = Policy_;

    /// Warp-level Mma
    using Operator = typename Policy::Operator;

    /// Shape describing the overall GEMM computed from shared memory
    /// by each warp.
    using WarpGemm = typename Policy::Operator::Shape;
    static int const kWarpGemmIterations = (WarpGemm::kK / Operator::Policy::MmaShape::kK);

    static_assert(kWarpGemmIterations > 1,
                    "The pipelined structure requires at least two warp-level "
                    "GEMM operations.");
};

so i want know how could i do to fix it, thanks !
