ERROR_DEVICE_LOST running vulkan_samples batch (Linux X11) #1078
Comments
What sample does crash? And what does the log look like before the crash? And on what device did the crash occur? |
@SaschaWillems GPU: Intel(R) UHD Graphics (CML GT2) Exact command: ./build/linux/app/bin/Release/x86_64/vulkan_samples sample descriptor_buffer_basic Log:
Can you explain what is log lock file? I will get it |
Are you sure that Intel GPU supports descriptor buffers? |
I am not sure, I just run samples in batch, and got error. |
That GPU most probably does not support that extension, which is the reason for the crash. Can you run that sample standalone instead of the batch mode? That should do proper error checking and tell you if that extension is supported or not. |
In batch mode it crashes faster. |
Looks like the GPU supports descriptor buffers. So either the sample is broken, or the driver. Do you get any validation errors when running with validation enabled? |
Here is log/errors with validation enabled:
|
Thank you very much. So from the validation layer messages it looks like that Intel device only supports a single descriptor buffer binding, but the sample requires more. Such a low limit makes me wonder why that device supports the extension after all. But to sum it up: The sample in it's current state simply won't work on your Intel GPU. |
Ok thank you |
We should add some startup-checks against |
Environment:
Arch Linux
Intel GPU + Nvidia GPU
X11

Result:
After some samples I got error:
