4 years ago Hi, thanks for the detailed report, however I can't see what's causing the problems. Just a quick thought: does vkcube run without primus_vk (i.e. on the intel graphics)? That stacktrace looks particularly wired, as primus_vk is not in that stack. Could you also try VK_LOADER_DEBUG=all pvkrun vkcube? Maybe the vulkan loader debug shows valuable information. As the application is crashing in a call to dl_close this looks particularly strange.
Regarding debugging Steam applications: You can run most steam applications directly, if you set the environment right. Mostly they just require SteamAppId to be set to the AppId of the game you are trying to run (i.e. SteamAppId=<appid> pvkrun ./some_steam_game_executable).

Problems I am experiencing with PrimusVK
vulkaninfosegfaults halfway through (log attached)vkcube(C version) doesn't work at all, instant segfaultvkcubepp(C++ version) works without issues perfectly fineDuring my testing I only tested native Linux applications. I don't care about wine/proton for now.
All testing was made with 3b268b4d1fdeaebeb399acacab60652cd2a72ca8 (
preview_cleanupbranch).This is how I installed primus-vk: https://github.com/magiruuvelvet/gentoo-overlay/commit/2fde105fd31c45f5350ad5eec4b1fda3381c87cf
The package looks like this:

I'm trying to wrap my mind around why random stuff works and others don't. Its an RNG game at this point. I also couldn't get Steam games to work at all. They segfault just like
vkcubedoes. Also that vulkaninfo segfaults halfway trough and not instantly seems strange to me.The only thing working reliably is RPCS3 right now. I don't have many games or emulators to test which also supports Vulkan. I have 2 AAA native Linux games which are Vulkan exclusive (devs didn't gave a shit about OpenGL) to do further testing once I figure out how to get a backtrace from those (Steam DRM is a b***).
Some additional context: nvidia-xrun works perfectly fine in terms of Vulkan, but its annoying to constantly switch ttys and I would like to get PrimusVK to work reliably. I have a feeling OpenGL is vanishing away and as a Muxless Optimus Laptop owner I'm starting to get worried.
EDIT: Forgot to mention my entire system is based on LLVM, clang and lld. GNU is a second class citizen on my custom LLVM-based userland and only available as compatibility layer with symlink hacks.
