Crash on linux (default backend - vulkan) with custom window handle and native display is NULL #3186

Closed alemuntoni closed 12 months ago

alemuntoni commented 1 year ago

I was trying to initialize and draw something with bgfx on Linux with Qt, and I encountered a crash when the bgfx::init function is called leaving platformData.ndt == NULL:

QWindow* w = new QWindow;

bgfx::Init init;
init.resolution.width = 640;
init.resolution.height = 480;
init.resolution.reset = BGFX_RESET_VSYNC;
init.platformData.nwh = reinterpret_cast<void*>(w->winId());
bgfx::setPlatformData(init.platformData);
bgfx::init(init);

At first, I thought that ndt was required, but then I noticed that setting init.type = bgfx::RendererType::OpenGL prevented the crash from happening. After some research, I found that a similar issue with OpenGL had been resolved in issue #1559, so I believe it can be resolved in a similar way for Vulkan.

The crash occurs here:

https://github.com/bkaradzic/bgfx/blob/448a42a8c6511725fa7ead0d1319b44577550d3a/src/renderer_vk.cpp#L6821

I tried to temporarily solve the problem in a way similar to what was done for issue #1559 by adding the following lines before the line that causes the crash:

if (NULL == g_platformData.ndt) {
    g_platformData.ndt = XOpenDisplay(NULL);
    BGFX_FATAL(g_platformData.ndt, Fatal::UnableToInitialize, "XOpenDisplay(NULL) : Failed to open default display");
}

and this fix seems to solve the crash and initializes everything correctly (although I am pretty sure that the same check is required also in some other places, e.g. for wayland).

Not being familiar with bgfx (I'm trying to use it for the first time), I'm not even sure if this approach is the right way to solve the problem. But could it be a solution to prevent ndt from being a mandatory requirement when using Vulkan?

a) Check if the issue can be reproduced with a bgfx-example. b) Check on a full-stack dump and the according bgfx debug-log. c) Since Qt is used for the front-end, also check what kind of window is used: e.g. child-windows might not be supported by the underlaying vulkan-driver (*). d) See if the issue remains with another vulkan-driver, on another hardware (e.g. AMD vs. nVidia).

If it's an issue with the underlaying drivers, please help to find out what e.g. vulkan-attribut should be considered by the bgfx code, to avoid running into this particular crash (hence, stack dump and debug-logs).

*) I have seen buggy vulkan-drivers when it comes to unsupported or half-supported window-styles, in particular with AMD drivers on Linux, but even on Windows.

a) Check if the issue can be reproduced with a bgfx-example.

I did some testing and it seems that Qt is not the cause. The behavior is consistent in the examples as well, even when using GLFW.

It can be reproduced in any BGFX example by setting init.platformData.ndt = nullptr. For example, here: https://github.com/bkaradzic/bgfx/blob/448a42a8c6511725fa7ead0d1319b44577550d3a/examples/00-helloworld/helloworld.cpp#L36

Please note that modifying (in any example):

init.type = bgfx::RendererType::OpenGL;
init.platformData.ndt  = nullptr;

makes it work. It appears that ndt is required under Vulkan, but not under OpenGL. Is it possible to make ndt optional, as it was done when #1559 was resolved?

I also created a small example using GLFW:

#include <bx/bx.h>
#include <bgfx/bgfx.h>
#include <bgfx/platform.h>
#include <GLFW/glfw3.h>
#if BX_PLATFORM_LINUX
#define GLFW_EXPOSE_NATIVE_X11
#elif BX_PLATFORM_WINDOWS
#define GLFW_EXPOSE_NATIVE_WIN32
#elif BX_PLATFORM_OSX
#define GLFW_EXPOSE_NATIVE_COCOA
#endif
#include <GLFW/glfw3native.h>

int main(int argc, char **argv)
{
    if (!glfwInit())
        return 1;
    glfwWindowHint(GLFW_CLIENT_API, GLFW_NO_API);
    GLFWwindow *window = glfwCreateWindow(1024, 768, "helloworld", nullptr, nullptr);
    if (!window)
        return 1;
    bgfx::Init init;
#if BX_PLATFORM_LINUX || BX_PLATFORM_BSD
    init.platformData.ndt = nullptr; // was glfwGetX11Display();
    init.platformData.nwh = (void*)(uintptr_t)glfwGetX11Window(window);
#elif BX_PLATFORM_OSX
    init.platformData.nwh = glfwGetCocoaWindow(window);
#elif BX_PLATFORM_WINDOWS
    init.platformData.nwh = glfwGetWin32Window(window);
#endif
    int width, height;
    glfwGetWindowSize(window, &width, &height);
    init.resolution.width = (uint32_t)width;
    init.resolution.height = (uint32_t)height;
    init.resolution.reset = BGFX_RESET_VSYNC;
    if (!bgfx::init(init))
        return 1;

    // clear and render loop here - omitting     

    bgfx::shutdown();
    glfwTerminate();
    return 0;
}

The behaviour is the same. It cashes with Vulkan when ndt is nullptr, it works with OpenGL.

b) Check on a full-stack dump and the according bgfx debug-log.

d) See if the issue remains with another vulkan-driver, on another hardware (e.g. AMD vs. nVidia).

I tested it on two NVIDIA GPUs. I don't have access to other hardware for testing, but it appears to me that implementing a check on the ndt value could potentially prevent the crash, similar to what is done with OpenGL #1559 .

Hi alemuntoni, thanks for the log.

The debug log indicates that vkCreateXlibSurfaceKHR is not available (nullptr): bgfx/src/renderer_vk.cpp (1356): BGFX 0x0 vkCreateXlibSurfaceKHR

vkCreateXlibSurfaceKHR does require a valid ndt (dpy) handle (see VkXlibSurfaceCreateInfoKHR) used in SwapChainVK::createSurface() for a X11 driver platform. Thus, pointing out that a Wayland (vkCreateWaylandSurfaceKHR) driver platform is used, which would not require a valid ndt handle. To enable Wayland define the bgfx compiler flag WL_EGL_PLATFORM.

Hi @Chris1AA, thank you!

I think that I am missing something: where is pointed out that a Wayland platform is used? I am trying to avoid it because Qt still does not support it well. Is there something on the log that points to Wayland instead of X?

Chris1AA commented 12 months ago

Search your log for vkCreateXlibSurfaceKHR and find _bgfx/src/renderervk.cpp (1356): BGFX 0x0 vkCreateXlibSurfaceKHR See SwapChainVK::createSurface() in renderer_vk.cpp.

Xlib is the default implementation for Linux, Wayland is an option. Since vkCreateXlibSurfaceKHR is not available (function pointer is 0x0) by the underlaying mesa/nvidia platform drivers, Wayland may be implemented (vkCreateWaylandSurfaceKHR).

Check what applies to your installed environment (what is supported by your mesa + nvidia backends).

alemuntoni commented 12 months ago

Oh, I see. Thanks, @Chris1AA, and I apologize for taking up your time. I genuinely thought there was the same bug as the old OpenGL issue, but it appears that my system is more messed up than I had realized. I'll check it and I'll ask for help in the discord channel, if needed.

Thank you very much for bgfx!
