Chromium and weston on i.MX8m Mini

[bdlr2]

Hello,

I'm trying to start-up chromium on an i.MX8m mini-based system.

I built a Linux distro with Yocto and the meta-imx layers, version langdale.I can compile chromium-ozone-wayland version 101.0.4951.54, but the issue is to start it on the device.

First, I start weston with

/usr/bin/weston --log=/run/user/0/weston.log --modules=systemd-notify.so

and I see the weston desktop, from where I can open weston-terminal (or example).

Then I start chromium with 

XDG_RUNTIME_DIR=/run/user/0/ WAYLAND_DISPLAY=wayland-1 WESTON_USER=root WAYLAND_DEBUG=1 chromium --no-sandbox --disable-features=VizDisplayCompositor --in-process-gpu --disable-gpu-rasterization --enable-features=UseOzonePlatform --ozone-platform=wayland chrome://gpu &

Chromium seems to start, because I get the following output 

[4154121.061]  -> wl_display@1.get_registry(new id wl_registry@2)

 Then the display freeze to the state it was before I typed the chromium command (so weston shell, with 1 terminal opened on it). No chromium window shown.

The only way to unblock the system is to reboot.

Has anyone experience with this ?

Following this issue, I continued to make my researches.

It turns out that I have a more general GPU problem. The GPU seems to crash and gives this debug info:

[   33.400449] **************************

 The above happened after starting gputop from command line.

How can this be solved ?

Hello @bdlr2,

I hope you are doing well.
Please accept my apology for the delayed response.

->One can check if it is caused by GPU supply,
-The GPU is powered by a dedicated power VDD_GPU. In order to support DVFS for both high-performance and low-power use cases, it should support the following operating range:
• 0.8V (0.8V +/-10%), up to 800MHz
• 0.9V (0.9V +5%/-10%), up to 1000MHz

In case of if frequency might be a root problem then please refer to this link for reference.
https://community.nxp.com/t5/i-MX-Processors/i-MX8M-Mini-GPU-Frequency-500MHz-How-to-increase/td-p/1...

It appears from the logs you have provided that at the address 0x18402090 GPU cannot fetch the correct command.
can you check the buffer content for the address?

Thanks & Regards,

Hi @bdlr2 

I hope you are doing well.

Please try with the below command.
