Ubuntu-frame not starting on device using imx-drm

snap
1

Hi,

Working on a arm dev board that supports a imx8mp, which has a small touch screen connected via a MIPI DSI. Thought I would try running ubuntu-frame, but it’s failing to start fully.

Final error seems to be Mir fatal error: Failed to perform buffer swap , but I will include the full log below in case there are other clues.

If anyone has any pointers to getting it working it would be appreciated :+1:

Here is the log:

Hi @jocado,

The driver requirements for Frame are described here:

I can’t find much information on the Mesa imx-drm drivers, but I suspect that they are not capable of supporting Frame.

[edit]

The best approach to getting Frame working on a board like this would be to package the propitiatory Vivante drivers as a content snap using the graphics-core20 interface. Technically, that should “just work”, but you’d need to check the legality of distributing these drivers.

3

the free evnativ driver should be enough to get working GLES …

4

Thanks Both. I’m hunting around for info about the Vivante drivers atm.

@ogra I’m not familiar with the driver you mentioned - can you share a link to point me in the right direction ?

Cheers, Just

5

oops, sorry, i did a dyslexic typo :slight_smile: it is etnaviv

https://github.com/etnaviv

it should be in the kernel tree since 2016 though:

https://lists.freedesktop.org/archives/dri-devel/2015-December/096202.html

6

Let’s just say I can very much relate to that :slightly_smiling_face:

Great - thanks for the info, will dig into it :+1:

Cheers, Just

7

@jocado you might find the Etnaviv drivers in kisak-core20. This is essentially an updated version of Mesa compared to the mesa-core20 snap that Frame uses by default:

snap install --edge kisak-core20
snap disconnect ubuntu-frame:graphics-core20
snap connect ubuntu-frame:graphics-core20 kisak-core20
8

Thanks @alan_g

I installed that, and it does contain etnaviv_dri.so. However, I’m not seeing an obvious way to specify which driver to try and use for a given card, and it still tries to load imx-drm_dri.so

I have checked both:

…and various forum posts.

Are you able to give me a pointer ?

Cheers, Just

9

What host OS are you using? You probably need a kernel configured with Vivante GPU support.

10

It’s Ubuntu Core 20, but with a custom kernel. I will try adding that configuration now :+1:

Cheers, Just

11

Hi Jocado,

I have the same behaviour on IMX8MP SOC. Kernel is compiled with Galcore version 6.4.3.p2.336687( Vivante driver ) . Did you solve the issue ?

12

Unfortunately not.

After making sure the kernel option was in place CONFIG_DRM_ETNAVIV=y , it still didn’t work. I intended to dig into it a bit more, but haven’t had the time yet I’m afraid.

Cheers, Just
