@Strit When you build the next mesa-git package, would it be possible to include the vulkan test apps as seen here?
Edit: Hmm, but I guess this would cause a conflict with the mesa-demos package… which has not been updated in several months, so it is missing vkcube and I assume a newer version of gears which shows the driver info.
You mean like this:
That’s been in the package for about a month.
I have not built the mesa-git package myself so I am not positive, but I wonder if [vkcube, gears] could be included here? I am looking for /usr/bin/vkcube and when I run /usr/bin/gears it does not display the driver info as it does in the video link. I assume it is an updated version of gears.
Edit: Or any other tool that displays at least the fps, so I can use it to help track the progress of the vulkan driver’s performance. (See video at 1:30 for gears and at 9:15 for vkcube.)
Ah, it would appear that a version of vkcube is in the AUR, if a little old.
https://aur.archlinux.org/packages/vkcube-git/
Maybe I can I use it. I’ll try it this evening when I am in front of my unstable version.
Install vulkan-tools.
I’ll give it a try too, thank you.
I just went through a world of headaches when I was trying vulkan today. I had done an update with the stable branch yesterday. I could not get going with vulkan and discovered that glxgears was not working. I installed mesa-git from stable and unstable and no glxgears. Then I installed mesa back in stable and no glxgears.
Bottom line is the new mesa in stable is messed up and mesa-git is messed up in stable and unstable. I had to revert mesa in stable to 20.2.1-1.
extra/mesa 20.2.2-2 [installed: 20.2.1-1]
Wowza, not great news. Hopefully Sunday’s mesa-git pull with change things. Some combination of things must be working, how else could they be developing and merging the v3dv driver? (rhetorical)
I’m pretty sure the v3dv driver is still only in master git (21.0 branch), so that does not explain why 20.2.2 does not work.
We have narrowed it down to be Raspberry Pi specific though, as the PBP has no issues on 20.2.2.
mesa-20.2.3-1 does not work with glxgears also.
[ray@pi4 ~]$ glxgears
Error: couldn't get an RGB, Double-buffered visualI just updated on unstable to mesa 20.2.3-1 on the rc5 kernel and I have the v3d driver loaded and no issue with glxgears.
I just updated on unstable to mesa-git 21.0.0_devel on the rc5 kernel

Edit: And vulkan-tools included vkcube, thank you. I do have a spinning cube. I am still looking for that version of gears. It shows a true fps beyond the vertical sync, which will give a quantifiable measurement to the driver’s progress.

Well, not continuing to repeat. 
@Strit I found the vulkan gears app. It is not a part of Mesa but rather a part of the Official Khronos Vulkan Samples.
Edit: I have opened a bug report with Arch Linux to have vulkan gears added to the vulkan-tools package.
There has been a lot going on regarding Vulkan for v3d (v3dv) in mesa git lately. Hopefully it stabilizes soon.
@Darksky Just to make sure the issue is not board version specific, I was successful loading the V3D driver on a 4GB RPi4.
