quick question...is there a possibility to accelerate the graphics output for a Raspi 3? There is a package X11-raspberrypi, but that seems not to contain any drivers or hints

To answer my own question: I stumbled over xf86-video-fbturbo, which seems to offer what I'm looking for:

Hardware accelerated window moving/scrolling on Raspberry Pi (using the BCM2835 DMA Controller)

hwinfo | grep bcm2835 gives a bunch of entries

In fact loading the module fails:

raspi:/home/test # insmod /usr/lib64/xorg/modules/drivers/fbturbo_drv.so insmod: ERROR: could not insert module /usr/lib64/xorg/modules/drivers/ fbturbo_drv.so: Invalid module format

Most likely, by the name and location, this is *not* a kernel module, but an Xorg driver.

...

Any idea what this means, or how to solve it? Or is ist the wrong driver at all?

Hm, that's strange. Do you boot a custom kernel?

I asked our graphics specialist Patrik (in CC) and he told me the following:

<paste> To enable 3D acceleration you need to: 1) Install Mesa-dri-vc4 package 2) Edit /etc/X11/Xorg.conf.d/20-kms.conf and remove the line: Option "AccelMethod" "none"

This will enable Mesa 3D acceleration and 2D acceleration in X with Glamor.

Does that also work with the upstream/openSUSE kernel? My experience with almost anything hw-accelerated on raspberry Pi (I only tried video decoding and encoding for now) is, that it only works on 32bits (the code is basically a NOP for 64bit userspace) and on raspbian-patched kernels. -- Stefan Seyfried "For a successful technology, reality must take precedence over public relations, for nature cannot be fooled." -- Richard Feynman -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

Yes, right. *.so isn't a kernel modules... I should read better before responding.

I don't know, we have to ask Patrik as he tested it (I added him back into CC as you dropped him).

I just tried the Mesa-dri-vc4 package, and the effect is amazing: Now the windows scroll smoothly over the screen, even under load (graphical desktop, database- and application server running) Thanks for the hint. I will add it to the wiki! Cheers Axel -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

Right, *.so is not a kernel module. I should have catched that...

We have to ask Patrik as he provided the info. I added him back to the CC list, as you (accidentally?) dropped him. Regards, Matthias
