Vulkan not working after power outage
Take a look at Vulkan Loader Debugging, try running vulkaninfo with set VK_LOADER_DEBUG=all.
- Why do we need the Vulkan Loader? [Linux]
-
SQ3 - QCOM vulkan support?
probably not given this response from 2021 https://github.com/KhronosGroup/Vulkan-Loader/issues/536
- Vulkan app crashing on certain PC's

How does Steam on Flatpak work?
Every program that needs Vulkan does indeed link against and call something with a well-known, long-time stable ABI. This is normally Vulkan-Loader, which provides libvulkan. For OpenGL, libglvnd is a nearly equivalent library that fulfills largely the same function and provides libGL/libGLES/etc.

Is the loader in integral part of the Vulkan API?
I'm reading through the official docs before I start a tutorial. The docs mention the loader but not very often. It does link to the loader's docs on github. I've read most of that. I still don't understand if it's an integral part of the API or just a tooling for certain use cases (multiple drivers, complex validation, etc.). I also listened to a webinar about the loader and the speaker claims he is the owner of the loader. That made me even more confused. Can someone please fill me in? Do all Vulkan apps interface with the loader before the driver? Thanks.

In Vulkan where the function set_api_version is defined?
It's from here: https://github.com/KhronosGroup/Vulkan-Loader/blob/393e23f91d21ce117c19e8c42e084477c3a25c7c/tests/framework/test_util.h
-
Multiple ICDs and instance extensions
Not exactly sure, but what you describe seems similar to the issue https://github.com/KhronosGroup/Vulkan-Loader/issues/776 .

What is the real use of vkGetInstanceProcAddr( )?
This would be good to read to understand why some of the things are the way they are. https://github.com/KhronosGroup/Vulkan-Loader/blob/master/docs/LoaderApplicationInterface.md

The Return of the Frame Pointers
I think I might have confused two unrelated posts. The one that references Polar Signals is this one:
https://gitlab.com/freedesktop-sdk/freedesktop-sdk/-/issues/...
So not a perf issue there, but they don't think the workflow is suitable for whole-system profiling. Perf issues were in the context of `perf` using DWARF:

- Finally mesa version 23.1.1 for fedora 38 has been published for testing 11 hours ago. It comes with quite important features like vulkan gpl for RADV to fight stutters in games and for better performance.

Yocto
But the fd-sdk https://gitlab.com/freedesktop-sdk/freedesktop-sdk and gnome build meta https://gitlab.gnome.org/GNOME/gnome-build-meta projects can prove as good references.

Rant: Desktop Sandboxing
With all of these hypothetical features out of the way and looking just at current release software, Flatpak allows you to do so much stuff that isn't accessible for a not-so-techy user. Custom installation folder? Yep. Running mesa-git GPU drivers? You got it. Any way to easily do this via GUI? In typical Linux fashion, nope. For a GUI focused packaging format this is a big letdown.
- Issue found for: Steam Deck Issue With Flatpak Hardware Decoding
- Steam Flatpak. Tried RADV_PERFTEST=gpl with proton-ge-54 but doesnt seem to be working when compared to using it with Bottles. Please see if I did it right.

Is there any way to force a specific Mesa driver for applications when multiple Mesa driver versions have been installed?
Link to (official?) how-to: https://gitlab.com/freedesktop-sdk/freedesktop-sdk/-/wikis/Mesa-git

Fedora Workstation 38 Is Shaping Up To Be Another Fantastic Release
You can load up Mesa GIT using environment variables, see here. Honestly what I miss the most from flatpak Steam is properly working non-Steam shortcuts, but I've given up on that.
- Are all AMD GPUs equally well supported?

PSA: The new OBS update breaks VA-API encoding when used with the Flatpak
It was my understanding that the packages for vaapi are just put into the -extra version of the sdk so app maintainers can opt out, but they are still available if they want to use them. See https://gitlab.com/freedesktop-sdk/freedesktop-sdk/-/merge_requests/10616
