QT+Vulkan crash test on Nvidia Thor

This repository provides a simple example that produce a vulkan driver error on the Nvidia Thor device

Prerequisites:

• NVidia Thor or Orin dev kit, up-to date as of 25/10/14
  • Thor: Tegra R38.2.1
  • Orin: Tegra R36.4.7
• Qt 6.8.3, extracted to ./Qt form Qt-thor.tar.gz or Qt-orin.tar.gz:
  • $ tar xvf Qt-thor.tar.gz
• Qt dependencies:
  • $ sudo apt install libvulkan-dev libx11-xcb1 libfontconfig1-dev libfreetype6-dev libx11-dev libx11-xcb-dev libxext-dev libxfixes-dev libxi-dev libxrender-dev libxcb1-dev libxcb-glx0-dev libxcb-keysyms1-dev libxcb-image0-dev libxcb-shm0-dev libxcb-icccm4-dev libxcb-sync-dev libxcb-xfixes0-dev libxcb-shape0-dev libxcb-randr0-dev libxcb-render-util0-dev libxcb-util-dev libxcb-xinerama0-dev libxcb-xkb-dev libxkbcommon-dev libxkbcommon-x11-dev libxcb-cursor-dev libpulse-dev

Run sample

Start with the qml interpreter:

$ ./Qt/bin/qml -style Universal -r vulkan Main.qml

Then click on the Open button.

Observed behavior:

• The interface hangs, the button disappear or display garbage triangles
• After a few seconds those messages appears:

Device loss detected in vkQueueSubmit()
Graphics device lost, cleaning up scenegraph and releasing RHI

• dmesg show those errors:

Notes

• The problem only appened when using vulkan, not opengl
• Removing some part of the test will make it work
