Hi,

Does anyone know what is the difference between mesa-arm-git and mesa-panfrost-git build in “archlinuxdroid” repo?

mesa-panfrost-git belongs to the first tests of jgmdev who setup archlinuxdroid repo. He wrote you should better use mesa-arm-git instead because this contains the most recent updates of mesa.

Hm, that is surprising low.

Here are results of jgmdev running glmark2-es2 before it crashed:

And that’s not all, video acceleration works too (tested with mpv)!!!

Does not work perfectly for me. I still have dropped frames (~9 fps) on X96Max+ with Mali G31. Maybe because libvdpau_meson and libcuda are missing. Did not find it in one of the packages.

Wow is like up to 6 times slow 52 fps vs 312 fps for the first test! May be some other settings might be involved to optimize the performance.

There was an update of mesa-arm-git (Mesa 21.0.0-devel (git-1200f6da0b) and just update it and ran glmark2-es2 (glmark2 20.20.04) and GT King Pro score is slightly lower 41.

Do you have to install any other packages from the repo other than mesa-arm-git for the video hardware acceleration?

[JFL]

Hi Strit,

You are using an Odroid N2, how is your N2 glmark2-es2 score like?

[JFL]

Hi Spikerguy,

Your GT King Pro have a higher speed than mine Rev A. How is your glmark2-es2 like with Panfrost.

[JFL]

TheMojoMan,

Somehow, glmark2-es2-wayland doesn’t start.
[jfl@GTKPro ~]$ glmark2-es2-wayland
Error: main: Could not initialize canvas

[Strit]

Don’t know. Haven’t tried.

Will try when I get a larger drive, so I can actually install stuff.

[TheMojoMan]

@JFL

Somehow, glmark2-es2-wayland doesn’t start.

This does not work when using XFCE. You have to use wayland instead of X11. You might install gnome or sway to test it.

Thanks for the info. Will stick with Xfce for the time being.

Today, I’ve struggled panfrost on odroid-N2 & testing branch.
all os images were built by manjaro-arm-installer.

• KDE + kernel 5.9.8-2 + mesa = no panfrost
• KDE + kernel 5.9.8-2 + mesa-git = panfrost, glxgears with 60fps but crash X(screen freeze) frequently
• xfce + kernel 5.9.8-2 + mesa = no panfrost
• xfce + kernel 5.9.8-2 + mesa-git = panfrost, glxgears with 40-50fps but crash X frequently

I also tried mesa-arm-git but frequent X crashes(screen freeze) were still existing.
(I didnt check dmsg when crashes occured, sorry)

My conclusion is that panfrost on odroid-N2 is hard to work so far. I’ll keep tracking after the next testing branch release.

[spikerguy]

Thank you very much for testing out so many probabilities.

Highly appreciate your work and yes panfrost is causing freezing but you can switch to waylanf on. Kde and try.

I think it doesnt freeze on wayland.

Cheers

[na0ki]

wayland is enable with KDE by default but it seems causing freeze.
(the installed version is based on testing branch, of course)

Looking at your glmark2-es2 results with a supposedly lower GPU (and with a much earlier mesa-git-20.3.0) than in GTKPro with G52 and your score is significantly better and the Odroid N2 results by jgmdev are way better. This lead me to suspect that Manjaro image for GT King Pro have not been optimized, missing drivers or enviromental set up?

[Strit]

I know you guys are excited for Panfrost on the Bifrost architectures. But it’s still very early days.

It’s normal for results to be all over the place, when the development moves as quickly as it does.

You don’t see users testing Alpha drivers for Nvidia cards, do you?

The fact that it’s actually just around the corner is a amazing to be honest. So I don’t get the “your benchmark score is higher than mine” thing. It means absolutely nothing this early in the development cycle.

[SickOS]

I hope we all know Panfrost is under development!

I see improvements almost every day and like Strit says this is very exciting. I just want to cry for all the people involved in this BRAVO!!!

[Strit]

I see there was a bunch of commits on the 17th relating to Bifrost, so the mesa-git package that hits Unstable branch on sunday will be exciting I think.
