i.MX6s/dl Etnaviv/Vivante drivers on Debian 9 Stretch

Hi everyone,

 

it's the same old problem on and on and perhaps someone can finally point me the way to get graphics acceleration to work.

 

I have a custom i.MX6s/dl Board with a little display and want to use the graphics acceleration. I built a Linux-Kernel with the Mainline Sources of Version 4.9.98.

 

I don't use yocto or another build-tool! I'm fine with my self-made compile-script for the Kernel.

 

The Graphic-Devicetree-Part is attached.

In Kernel-Config / Drivers / Graphics support the following is selected:

- IPUv3 core support

- Direct Rendering Manager

- DRM Support for Freescale i.MX

- Support for parallel displays
- Support for TV and VGA displays
- Support for LVDS displays
- Freescale i.MX DRM HDMI

- ETNAVIV

(- Backlight support and Bootup logo)

 

The Etnaviv Module seems to be working correctly, <dmesg|grep viv> gives:

[ 1.482134] etnaviv gpu-subsystem: bound 134000.gpu (ops gpu_ops)
[ 1.488314] etnaviv gpu-subsystem: bound 130000.gpu (ops gpu_ops)
[ 1.494468] etnaviv-gpu 134000.gpu: model: GC320, revision: 5007
[ 1.546746] etnaviv-gpu 130000.gpu: model: GC880, revision: 5106
[ 8.556667] etnaviv: module is already loaded

 

The Root-Filesystem (Debian 9) is built with the receipe here:

Debian on the i.MX6 sabre sd platform in a few commands

except I replaced
# debootstrap --foreign --arch=armhf testing /mnt

with

# debootstrap --foreign --arch=armhf stable /mnt

 

After the basic Installation I added lightdm and xfce4. This works fine for me except the missing graphics acceleration.

And I added some mesa packages (Version 13 in Debian 9):

libegl1-mesa, libegl1-mesa-drivers, libgl1-mesa-dri, libgl1-mesa-glx, libglapi-mesa, libglu1-mesa, mesa-common-dev, mesa-va-drivers, mesa-utils, mesa-utils-extra

With the mesa-utils I testet graphics with glxgears and got a fps of about 36 

 

I already tried countless ways to get the graphics acceleration to work but with no success. I don't want to list them here but here are some examples: (which are mostly very old)

- install armada (libdrm-armada) (not shipped with Debian)

- compile xorg-drv-vivante

- compile and install xf86-video-imx-vivante-rel_imx_4.9.x_1.0.0_ga (Compile Errors with incorrect defines and structures. Did not compile!) also added imx-gpu-viv-5.0.11.p8.4-hfp for headers and libs

 

Many (all) of them ended with compile errors which I can't solve.

 

i.MX6 is now a rather mature Device and I can't believe I'm the first to try this. Isn't there a working way to get Graphics-Acceleration to work?

Do you need any further Information?

 

PLEEEEAAAAAAAAAASE! HEEEEEEEELP! PLEEEEEEEAAAAAASE! (Multipass!)
