如何在调度着色器之前写入 ID3D11UnorderedAccessView 的缓冲区？

假设我有

ID3D11UnorderedAccessView* pDataView

我有

byte* pRawData

如何使用prawdata设置pdataview的缓冲区？

注意：失败和chr是错误检查摩克群。

更新：Soonts给出了一个答案，当我创建无人机时，似乎可以解决问题，但是为了完整的利益，我也希望能够在创建两者都可以从CPU上成功更新其缓冲区。我并没有那么成功。如果我有：

        template <typename T>
        static inline void CreateUnorderedAccessViewFromFile(
            _In_ ID3D11Device* pDevice,
            _In_ ID3D11DeviceContext* pDeviceContext,
            _In_ HANDLE dataFile,
            _Out_ ID3D11Buffer** ppBuffer,
            _Out_ ID3D11UnorderedAccessView** ppUav)
        {
            uint64_t fileSize;
            //CBR(::GetFileSizeEx(handle, &fileSize));
            //Custom size for testing purposes
            fileSize = 0x800;
            D3D11_BUFFER_DESC bufferDesc =
            {
                fileSize, // ByteWidth
                D3D11_USAGE_DEFAULT, // Usage
                D3D11_BIND_UNORDERED_ACCESS, // BindFlags
                D3D11_CPU_ACCESS_WRITE, // CPUAccessFlags
                D3D11_RESOURCE_MISC_BUFFER_STRUCTURED, // MiscFlags
                sizeof(T), // StructureByteStride
            };
            CHR(pDevice->CreateBuffer(
                &bufferDesc,
                nullptr,
                ppBuffer));

            D3D11_MAPPED_SUBRESOURCE mappedResource;
            HRESULT hr = pDeviceContext->Map(
                *ppBuffer,
                0,
                D3D11_MAP_WRITE_DISCARD,
                0,
                &mappedResource);
            byte* ppData = reinterpret_cast<byte*>(mappedResource.pData);
            for (uint64_t i = 0; i < fileSize; i += 0x10000)
            {
                DWORD readSize = min(fileSize - i, 0x10000);
                if (!ReadFile(
                    dataFile,
                    ppData,
                    readSize,
                    NULL,
                    NULL))
                {
                    uint32_t lastError = ::GetLastError();
                    CBR(lastError != ERROR_IO_PENDING);
                }
            }
            pDeviceContext->Unmap(
                *ppBuffer,
                0);
            D3D11_UNORDERED_ACCESS_VIEW_DESC uaView =
            {
                DXGI_FORMAT_UNKNOWN, // Format
                D3D11_UAV_DIMENSION_BUFFER, // ViewDimension
            };
            uaView.Buffer.FirstElement = 0;
            uaView.Buffer.Flags = 0;
            uaView.Buffer.NumElements = fileSize / sizeof(T);
            CHR(pDevice->CreateUnorderedAccessView(
                *ppBuffer,
                &uaView,
                ppUav));
        }

为什么我可以在地图上hr是e_invalidarg？
