(CI request) Provide Linux AppImage in nightly builds

[hardBSDk]

The major cross-platform emulators offer AppImages for Linux, like RPCS3 and PCSX2.

There are any blocker for this?

The biggest hurdle right now is that currently Linux is failing to build due to several issues. I'm not familiar with the current CI pipeline, but I'll definitely check this out once I get the remaining Linux build issues resolved.

Hi, @lucasmz1 made an AppImage here but for some reason Xenia creates a bunch of cache dirs in the current working directory?

Xenia-canary now has a proper compiling build now. I have integrated quite a lot of Linux stuff proposed here over the years and it just requires now a d3d12 back end implementation.

[Samueru-sama]

Another issue is that Xenia-canary tries to write to the bin directory where the binary is located. In the case of the appimage this fails because that gets mounted as read-only. So I have to extract the appimage and run the AppRun for now.

How is this handled if I build and install the binary on my PC? because in that case it means the app needs root rights in order to write to /usr/bin.

@RodoMa92 What about the Vulkan renderer progress?

@RodoMa92 What about the Vulkan renderer progress?

I'm evaluating gluing vkd3d native on top of the dx12 backend, but I can't promise anything yet.

The native Vulkan backend seems still a bit of a mess, and I'm not versed that much in graphics personally so I'm not sure on how much I can improve things there.

hi, I have an issue with audio, I dunno why what it is. I am curently runnin on e5 2650 v4, 16 gb of ram and gtx 1060 3gb, but no audio output, well to be honest I'm not using hdmi, I'm using an adaptator for display port to vga cause my monitor is not a big deal, any way I'm using the the back line out. but still not getting how to output the audio. any help is welcomed. thanks in andance.

@lucasmz1 This issue is not the correct place to report your problem, please join the Xenia Discord or create an issue for your problem.

Anything came out of this?

Not yet, the main problem is that they use this Microsoft compiler (https://github.com/microsoft/DirectXShaderCompiler) for translating shaders back into DX12, and it does seem to be a PITA to make it compile fine under Linux.

DXVK seems to basically map 1/1 as API goes (makes sense, it was designed for that), so that should already be mostly done as of now (headers still misses some DX12 constants, but they do seem to be present in the latest vkd3d include headers, so it should just be as easy as reexporting them from the .idl/"WINE format" structures).

I might have to evaluate using a different codepath for Linux, probably something based on GLSL/SPIR-V (https://github.com/KhronosGroup/glslang) that should do basically the same thing but with a codebase that is digestible to another OS. This is yet to be implemented.

In any case, my progress are open and on GitHub, so feel free to contribute to it: https://github.com/RodoMa92/xenia-canary/tree/linux_d3d12
