(Video) Vulkan and Linux with RADV

[Pickapart]

Hi, I have a Radeon R9 270x (Curaçao XT) so a GCN1.0 architecture. I have activated amdgpu free driver instead of radeonsi to have a chance to use Vulkan. Vulkan works like a charm on games which support it, like Talos Principle (just incredible, no bugs, no glitches). But on RetroArch Beetle PSX for example has full of bugs and glitches, even if the game is correctly launched. My question is : is Vulkan run correctly on GCN1.1+ so it cannot run well on GCN1.0 ? Is there any plan to have better support of Vulkan especially RADV driver in RetroArch ? Here a paste of log using Vulkan :

Can you please get a backtrace with debugging symbols?

Also what kernel and mesa versions do you have?

I use RetroArch from flathub repo (the rpm version isn't compiled with vulkan support). How to have a backtrace please ?

[gouchi]

Can you try to build it from source ? First install packages needed to build RA for Fedora. For Vulkan please install mesa-vulkan-drivers and mesa-vulkan-devel packages.

Then compile RA with

git clone https://github.com/libretro/RetroArch.git retroarch
cd retroarch
./configure --enable-vulkan && make clean && make DEBUG=1 GL_DEBUG=1 VULKAN_DEBUG=1

At last launch RA and get a backtrace.

gdb ./retroarch
r
bt full

Thank you.

@Themaister Got any experience with RADV and Vulkan?

[orbea]

@Pickapart Do you have any problems with the RetroArch menu and radv? Is it still a problem with the latest core builds? I think its probably a core and / or radv issue rather than RetroArch.

Can you open an issue report for the core tracker?

@Pickapart Please close this issue, if you don't reproduce it anymore.
