Triangle code failed

Vulkan

Hello,
I´m from Germany, so I can´t speak (and write) English very well. But my triangle code is crashing. It compiles but when I minimize the app-window every frame this error is coming:

UNASSIGNED-CoreValidation-DrawState-QueueForwardProgress(ERROR / SPEC): msgNum: 0 - VkQueue 0x64b37c8[] is waiting on VkNonDispatchableHandle 0xc84d0a000000000f[] that has no way to be signaled.

Does your code run correctly when you do NOT minimize the application’s window?

4

Check return code of acquire, esp. if it is ERROR_OUT_OF_DATE.

5

@johannesugb No the screen stays black and there isn´t a triangle.

6

The error code is

-1000001004

7

Per Vulkan spec, that is indeed VK_ERROR_OUT_OF_DATE_KHR. There you have your problem. vkAcquireNextImageKHR failed, and so the semaphore never gets signaled.

To fix it, you need to handle the minimization case (width==0, height==0).

8

What @krOoze has pointed out is also described in Vulkan Tutorial’s Swap chain recreation chapter. Maybe you can find some more useful information there.

But since you wrote that “the screen stays black and there isn’t a triangle”, does that mean that your code has never rendered a triangle, so far? I.e. there are more problems besides the swap chain recreation?

9

Thanks, to both of you. I´ve added this code to my project:

result = vkQueuePresentKHR(queue, &presentInfo);

if (result == VK_ERROR_OUT_OF_DATE_KHR)
{
    recreateSwapchain();
    return;
}
ASSERT_VULKAN(result);

But now I´m getting this error:

VUID-VkSwapchainCreateInfoKHR-imageExtent-01274(ERROR / SPEC): msgNum: 0 - vkCreateSwapchainKHR() called with imageExtent = (400,300), which is outside the bounds returned by vkGetPhysicalDeviceSurfaceCapabilitiesKHR(): currentExtent = (0,0), minImageExtent = (0,0), maxImageExtent = (0,0). The Vulkan spec states: imageExtent must be between minImageExtent and maxImageExtent, inclusive, where minImageExtent and maxImageExtent are members of the VkSurfaceCapabilitiesKHR structure returned by vkGetPhysicalDeviceSurfaceCapabilitiesKHR for the surface (https://www.khronos.org/registry/vulkan/specs/1.1-extensions/html/vkspec.html#VUID-VkSwapchainCreateInfoKHR-imageExtent-01274)
    Objects: 1
        [0] 0x4791118, type: 3, name: NULL

I understand it, but I don´t know how to fix it.

10

Best to show how I do it:

Besically, set swapchain to VK_NULL_HANDLE if you cannot create it, then in the event loop do if( swapchain ) drawFrame();. Of course, that also means you would be busy spinning the event loop, so if there is no swapchain, you might want to swap to the blocking glfwWaitEvents() and let it wait for you for any new resize event.
