Can't get 3D acceleration working on CM5

<< < (2/3) > >>

Juanito:
Can you attach Xorg.0.log?

I assume you’re using dtoverlay=vc4-kms-v3d?

xsquared:
I couldn't get my DSI display working with dtoverlay=vc4-kms-v3d, but got something working with dtoverlay=vc4-kms-dsi-generic

So maybe that's the problem, there's no 3d in the name! I'll have a look at the overlay dts files and see if I can make a Frankenstein version.

Xorg.0.log attached.

Juanito:
Whereas I have this in the xorg log:
--- Code: ---(**) |   |-->Device "broadcom"
...
(II) Loading sub module "glamoregl"
(II) LoadModule: "glamoregl"
(II) Loading /usr/local/lib/xorg/modules/libglamoregl.so
...
(II) modeset(0): glamor X acceleration enabled on V3D 4.2.14.0
(II) modeset(0): glamor initialized
--- End code ---

you have:
--- Code: --- (**) |   |-->Device "Intel Graphics"
...
(II) Loading sub module "glamoregl"
(II) LoadModule: "glamoregl"
(II) Loading /usr/local/lib/xorg/modules/libglamoregl.so
...
(II) modeset(0): Refusing to try glamor on llvmpipe
(II) modeset(0): glamor initialization failed
(**) modeset(0): DRI3 disabled
--- End code ---

I'm not sure why it shows an intel graphics device?

Did you load the Xorg-3d meta extension? Do you have the graphics-KERNEL extension loaded?

Juanito:
Do you need vc4-kms-v3d-pi5 maybe?

xsquared:
Good find, Juanito. The Intel was being pulled in from a config file I had in xorg.conf.d which appeared to work on the CM4 – attached – that I should probably remove.

Yes to both of your questions, I'm using Xorg-3d and graphics-KERNEL. And I did try vc4-kms-v3d-pi5 but couldn't get X to run at all.

So I need to figure out why
modeset(0): Refusing to try glamor on llvmpipe
is occurring.

Thanks so much for your help. I have to switch to another task now, but if I can get things working later this week, I'll post my solution here.
