Launching with Vulkan driver causes a segfault #165

RobertTheSable · 2020-09-09T01:51:12Z

Launching Dolphin build from the current master (f4f4947) with the Vulkan driver enabled and core driver switching disabled results in a segfault.

The driver appears to have been broken by the 5.0 rebase, as the last commit I can verify it worked on was cf6c736.

I'm running on Kubuntu 20.04 with an AMD Radeon RX 480 GPU, using the amdgpu driver. I'm not sure if it's a Linux specific issue or not.

bslenul · 2020-09-14T11:46:48Z

I'm not sure if it's a Linux specific issue or not.

Loads fine with Vulkan + "Allow Cores to Switch the Video Driver" OFF on Windows 10 at least.

yoyossef · 2020-11-09T15:41:44Z

I also have got the same issue on Manjaro (Arch Linux) with an Intel iGPU using mesa driver.

mikedebian · 2021-04-10T13:41:55Z

Same issue cf6ca2a47f

Vega 56, MESA
Arch Linux.

Two other cores I have loaded up, and stand alone dolphin emulator works fine with Vulkan.

Works in GL.

jason-oliveira · 2021-06-20T02:19:45Z

Seems this might be an amdgpu issue. I'm experiencing the same issue here as well. Works fine in GL (but slower), segfaults as soon as launched with vulkan. Standalone dolphin does Vulkan fine as well.

All I get GLX reporting invalid screen size results, and then the app crashes. here's a dump: https://hastebin.com/wuzediwone.sql

Libretro dolphin also crashes on my system.

OS: Arch Linux, kernel 5.12.15
GPU: Intel(R) HD Graphics 520 (SKL GT2)
Vulkan package: vulkan-intel 21.1.4 (mesa)
Vulkan Instance Version: 1.2.182
Retroarch: 1.9.6
Libretro-dolphin: 32990 (commit: 13ad7dd)

Setting retroarch

video_driver = "glcore" > works
video_driver = "vulkan" > segfault in retroarch

The vulkan renderer does work for other libretro backends.

Getting a backtrace by gdb gave me no interesting results due to debug symbols missing.
I am not what the best way is to provide more information.

Please instruct me if more information is needed.

zyoungdev · 2021-08-21T16:54:53Z

Arch Linux with Intel graphics. OpenGL works fine. I was able to get a backtrace out of libretro-dolphin.so but the segfault happens in the Vulkan library.

I can't reproduce the issue with nvidia driver under Xorg.

I tested with with homebrew Super Methane Brothers from content downloader.

So the issue will be related to Wayland and/or DRM/KMS only ?

65a · 2021-09-26T21:50:31Z

I can reproduce with KMS/Intel (Lakka) and Xorg/AMD (Arch). Same backtrace. It sounds like this might be everything but nVidia?

It's probably not Wayland since I wasn't using Wayland at the time of encountering the bug.

The check at

dolphin/Source/Core/VideoBackends/Vulkan/VulkanContext.cpp

Line 919 in 4ffaf05

    
           if (!vkGetPhysicalDeviceProperties2 || (VK_VERSION_MAJOR(m_device_properties.apiVersion) == 1 &&

ensures that vkGetPhysicalDeviceProperties2 is non-null (if it was null, we'd return on a short circuit evaluation of the statement there).

Your stack trace seems to indicate that gpu is also non-null, and the other argument to vkGetPhysicalDeviceProperties2 is initialized in this function.

My best conclusion is that vkGetPhysicalDeviceProperties2 is unhappy with gpu (aka m_physical_device)?

Igetin · 2022-03-06T20:49:50Z

Just reporting that I’m experiencing this problem as well, on the latest master (3b19e6d).

OS: Fedora 35
Windowing system: X11
Graphics driver: ADMGPU
GPU: Radeon RX 6800 XT

The GL driver seems to work fine.

@RobertTheSable The issue should be renamed to Launching with Mesa Vulkan driver causes a segfault. Thank you.

It seems vkGetPhysicalDeviceProperties2 is coming from Vulkan 1.1 but we are using Vulkan 1.0 context ?

But why it would work with Nvidia Vulkan driver ?

Sanaki · 2022-09-25T23:26:49Z

Verified this on the steam version on steam deck. Seems like it should be as simple as switching to requesting a 1.1 context then, right? Or am I missing something?

gouchi · 2023-02-04T16:54:36Z

I confirm this issue is fixed with this PR.

So running latest master or future RA 1.15.0 will fix this issue.

gouchi · 2023-04-29T17:48:11Z

@RobertTheSable Please close this issue as it has been fixed.

Thank you.
