Vulkan队列正在等待无法发出信号的信号量

Question

验证错误:

VUID-vkQueuePresentKHR-pWaitSemaphores-03268(ERROR / SPEC): msgNum: 622825338 - Validation Error: [ VUID-vkQueuePresentKHR-pWaitSemaphores-03268 ] Object 0: handle = 0x2ad2f2d8a38, type = VK_OBJECT_TYPE_QUEUE; Object 1: handle = 0xdd3a8a0000000015, type = VK_OBJECT_TYPE_SEMAPHORE; | MessageID = 0x251f8f7a | vkQueuePresentKHR: Queue VkQueue 0x2ad2f2d8a38[] is waiting on pWaitSemaphores[0] (VkSemaphore 0xdd3a8a0000000015[]) that has no way to be signaled. The Vulkan spec states: All elements of the pWaitSemaphores member of pPresentInfo must reference a semaphore signal operation that has been submitted for execution and any semaphore signal operations on which it depends (if any) must have also been submitted for execution (https://vulkan.lunarg.com/doc/view/1.2.182.0/windows/1.2-extensions/vkspec.html#VUID-vkQueuePresentKHR-pWaitSemaphores-03268)
Objects: 2
[0] 0x2ad2f2d8a38, type: 4, name: NULL
[1] 0xdd3a8a0000000015, type: 5, name: NULL

此错误发生在GraphicsQueue提交函数中。这是我要修正的最后一个错误。我不知道下一步该做什么。

我哪里做错了?

void SwapChain::SubmitCommandBuffer(const vk::CommandBuffer& buffer, const size_t imageIndex)
{
vk::Result result{};
if (_imagesInFlight[imageIndex])
{
result = _device.GetDevice().waitForFences(1, &_imagesInFlight[imageIndex], true, std::numeric_limits<uint64_t>::max());
if (result != vk::Result::eSuccess)
ENGINE_DEBUGBREAK();
}
_imagesInFlight[imageIndex] = _inFlightFences[_currentFrame];
result = _device.GetDevice().resetFences(1, &_inFlightFences[_currentFrame]);
if (result != vk::Result::eSuccess)
ENGINE_DEBUGBREAK();
const std::array<vk::PipelineStageFlags, 1> waitStages{ vk::PipelineStageFlagBits::eColorAttachmentOutput };
const std::array<vk::Semaphore, 1> whaitSemaphores{ _imageAvailableSemaphores[_currentFrame] };
const std::array<vk::Semaphore, 1> signalSemaphores{ _renderFinishedSemaphores[_currentFrame] };
const vk::SubmitInfo submitInfo
{
.waitSemaphoreCount = static_cast<uint32_t>(whaitSemaphores.size()),
.pWaitSemaphores = whaitSemaphores.data(),
.pWaitDstStageMask = waitStages.data(),
.commandBufferCount = 1,
.pCommandBuffers = &buffer,
.signalSemaphoreCount = static_cast<uint32_t>(signalSemaphores.size()),
.pSignalSemaphores = signalSemaphores.data(),
};
_device.GetGraphicsQueue().submit(submitInfo, _inFlightFences[_currentFrame]);
const std::array<vk::SwapchainKHR, 1> swapChains{ _swapChain.get() };
const uint32_t imgeIndexUint{ static_cast<uint32_t>(imageIndex) };
vk::PresentInfoKHR presentInfo
{
.pImageIndices = &imgeIndexUint,
};
presentInfo.setWaitSemaphores(whaitSemaphores);
presentInfo.setSwapchains(swapChains);
result = _device.GetPresentQueue().presentKHR(presentInfo);
if (result != vk::Result::eSuccess)
ENGINE_DEBUGBREAK();
_currentFrame = (_currentFrame + 1) % MAX_FRAMES_IN_FLIGHT;
}

或者错误的本质并不在这个函数中?

Answer 1

您发出_renderFinishedSemaphores[_currentFrame]信号量，但随后您等待另一个信号量:_imageAvailableSemaphores[_currentFrame]。
