c++ - vkWaitForFences 和 vkDeviceWaitIdle 不等待

Question

我刚买了一台使用 nvidia 显卡 (gtx 1060) 的新电脑，当我尝试运行我的程序(之前可以运行)时，我遇到了一堆错误，但大部分都已修复。我留下的一个问题是，vkWaitForFences() 和 vkDeviceWaitIdle 返回 VK_ERROR_DEVICE_LOST。我的旧计算机使用 amd 显卡，但确实很旧，我使用的是旧版本的 vulkan sdk，但我认为这不是问题所在。

当然，我用谷歌搜索了这个错误，这对我帮助不大，因为没有多少人遇到过这个问题。我发现这可能是驱动程序的问题，所以按照建议，我更新了 windows 和 nvidia 驱动程序。那并没有多大帮助。我还追踪了问题发生的位置，它总是在我第二次提交命令缓冲区时发生。设备丢失也是第二次发生。

我的提交命令功能，任何人都想知道为什么结果是大声笑，因为那是我总是为了快速调试而写的第一件事，并不是什么严重的事情。

    if (m_OldAllocCount == 0 || m_RecordCmdBuffers){
            recordPrimaryCmdBuffer();
        }

        VkResult lol = vkWaitForFences(m_ContextPtr->device, 1, &inFlightFences[current_frame], VK_TRUE, std::numeric_limits<uint64_t>::max());

        presentInfo.pSwapchains = swapChains;
        presentInfo.pImageIndices = &imageIndex;

        if (result == VK_ERROR_OUT_OF_DATE_KHR || result == VK_SUBOPTIMAL_KHR || m_CurrentWindow->windowResized()) {

            recreateSwapChain(m_CurrentWindow->getWindowSize());
            viewport(Vector2i(0), m_CurrentWindow->getWindowSize());
        }
        else if (result != VK_SUCCESS)
            throw std::runtime_error("failed to present swap chain image!");

        current_frame = (current_frame + 1) % MAX_FRAMES_IN_FLIGHT;

        if (m_AllocCount > 0)
        {
            m_CurrentCmdBuf = 0;
            m_OldAllocCount = m_AllocCount;
        }

这是我的输出

Answer 1

所以我解决了它，显然设备丢失是由于我的输出中的描述符插槽 0.1 而发生的，我认为这不是问题的原因是因为它在我的旧计算机上工作，即使那个错误弹出。我想这对于不同的 GPU 是不同的。它现在按预期工作，感谢任何试图提供帮助的人。
