[Linux] Wayland is broken on Kernels newer than 6.12 on Battlemage cards

[latent carbon]

Hey ho Intel Devs. i hope someone actually looks at this and could investigate this issue. Currently the Wayland Compositor is messed up on Linux Kernels newer than 6.12. Its running at half the speed than supposed to. this is reported here https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/4363

i am hoping someone can take a look at this as it makes using Battlemage cards god awful atm... and im afraid this will go unnoticed for a really long time...

"suffering" from the same bug, if anyone has a workaround or fix feel free to share. 🙂

There’s none other than either use X11 or downgrade to 6.12 sadly

[acoustic quest]

seems so, tried it with fedora 42 and its still there on 6.14, endeavourOS has the kernel-lts package with 6.12, that works

[latent carbon]

so hey

with some help we managed to find a workaround

add " xe.enable_dsb=0 " to the boot params

[acoustic quest]

oh, lemme try that

That seemed to work! Thanks for sharing the workaround, hopefully the fix won't take long

DUDE I WENT FROM 30 TO 1000 FPS IN MINECRAFT

[acoustic quest]

has anyone tested Battlemage on 6.15?

[latent carbon]

not much changed

still pretty mid

[acoustic quest]

seems kinda fixed with 6.17

[acoustic quest]

isnt

[vast glen]

oh lol I came back here to check if I can get rid of the param and who would've thought someone did that today as well

[noble hinge]

the devs probably dont check here, you should post it on github to get devs attention.

[latent carbon]

you do realize this is for windows only

[noble hinge]

doesn't hurt for you to try if you want the devs attention

[acoustic quest]

you realize this is literally a different team of developers

[latent carbon]

you realize intel has a open source team contributing to mesa?

yea weird isnt it

[acoustic quest]

yeah i know
