PROCESSOR-SDK-AM62X: Bad performance chromium-ozone-wayland with wayland/weston

Alexis LOGNON

Part Number: PROCESSOR-SDK-AM62X
Other Parts Discussed in Thread: SK-AM62

Hello,

I integrated the chromium-ozone-wayland recipe using the advises from TI team.
I added the following lines in the processor-sdk-08.04.01.04-config.txt files:

meta-browser,github.com/.../meta-browser.git,master,5f365ef0f842ba4651efe88787cf9c63bc8b6cb3,layers=
meta-python2,git.openembedded.org/meta-python2,dunfell,HEAD,layers=
OECORELAYERCONF=./sample-files/bblayers-dunfell-browser.conf.sample

I add chromium recipe to conf/local.conf:

DISTRO_FEATURES_append = " wayland"
CORE_IMAGE_EXTRA_INSTALL += "wayland weston weston-init"
IMAGE_INSTALL_append = " xenomai chromium-ozone-wayland"

1/ I launch weston with a non-root user from a systemd service at boot
2/ I launch my nginx server and my application from a systemd service
3/ I launch chromium pointing on the local nginx server from a systemd service.

The performances a really bad, the HTML app is not usable CSS animation are blinking.

So I stop all application and nginx server and add a simple html file with a simple CSS animation on the file system.
1/ I launch manually weston
2/ I launch chromium pointing on the local file
3/ CSS animation is blinking, the image is not fully refreshed, some white line appear.
4/ I open a terminal and check with top command to see the CPU usage.
- I saw that weston and chromium is using the most CPU ressources.
- But chromium is not using more than 40% of the CPU
- The animation is not displayed correctly weston use more than 60% of the CPU.
- So I check the linux journal and log messages but there is no error raised.

So I decided to use a lower resolution and go to 800x600 in weston.ini configuration file.
1/ I launch manually weston
2/ I launch chromium pointing on the local file

But the bug occurs less times but is still their.

So I tried to give a try to matrix-browser
1/ I launch matrix-browser from TI default image, after stop 3D demos.
2/ The HTML app is not displayed, the CSS animation is better, but I have blank pages instead of the app GUI.

A/ Could you help me to identify the issue, is the AM62x processor is not powerfull enough to make a CSS animation displayed correctly ?
B/ Is there some optimisation to apply to wayland/weston ?
C/ Is there an alternative to weston compositor ?
D/ Could help to chromium with xwayland
E/ The X11 feature is mentioned as experimental, is X11 is be supported by the SDK ?

Our product need a HTML5 compatible browser to display our HTML app, it a blocking point.
Could you provide us a solution ?

Have a nice day.

Regards,

Alexis.

Hello Alexis,

Thank you for your inquiry. Just to confirm, you are using a TI SK-AM62 EVM and you have disabled the GPU in the device tree, right?

Best regards,
François.

I didn't disable GPU at the platform level in the yocto configuration.

I tried in the chromium command line with and without the argument --disable-gpu, the problem is the same.

I rebuilding the SDK with the wekkit QT in order compare the performance of chromium and the matrix-browser.

Regards,

Alexis.

I done a new test today.

I rebuild my tisdk image with chromium and the QT Browser (qtwebkit-examples/examples/webkitwidgets/browser), and matrix-browser

I have the same issue for all browsers,top shows a CPU usage over 100%, then the CSS animation is partially refreshed.

Let me know how to fix this performance issue.

Regards.

Alexis.

Hello Alexis,

Thank you for the feedback and we are working towards improving our Chromium performance. Out of curiosity, do you encounter similar issue with QtWebgine? Based on my understanding, there are various types of browsers:

1. Native Chromium browser and it comes from the following project: https://github.com/OSSystems/meta-browser. Depending on the commit selected, your version will be different.

2. Qt's version of Chromium browser (QtWebengine) and depending on Qt version, Chromium backend will change. For example, we support Qt 5.14.2 and that uses version 77. Also, you can launch Qt application with Weston and EGLFS. I am wondering if you noticed better responsiveness with EGLFS.

3. Non Chromium based browser such as QtWebkit. I am not sure if a non-chromium based browser is an option here and when we launch matrix-gui with matrix browser it seems to work flawlessly. I do not think it uses fancy CSS animation so that's why the performance is better.

Krunal

Hello Krunal,

Could you give more information about the second point:

- Is there a recipe ready to use for the QT's version of Chromium I would like to check the performances ?

- If not how can I build this version ?

- How could I check that EGLFL is used by weston, is there some specific configuration to do ?

- Is QT's version of Chromium required a QT licence or is it free ?

Regards,

Alexis.

Hi Alexis,

In meta-qt5, there should be a recipe for qtwebengine that you can just enable. I believe you can do bitbake qtwebengine and it will build all the necessary components. In general, you can launch Qt applications using various platform plugins. For example, "<qt_app> --platform eglfs" or "--platform wayland". If you use eglfs, you need to disable weston (/etc/init.d/weston stop) and your application will launch in fullscreen mode. With regards to license, please refer to the recipe: https://github.com/meta-qt5/meta-qt5/blob/master/recipes-qt/qt5/qtwebengine_git.bb

Krunal

Hi Krunal,

Could you tell me how to enable eglfs is the tisdk ?

Should I remove wayland and weston by using DISTRO_FEATURES_remove = " wayland weston" ?

I build qtwebengine, but I didn't find recipe for chromium inside meta-qt5, only some patches.

How could I build qt's version of chromium instead of the chromium-ozone-wayland version ?

I had the CSS html test I used for my test, could you can test on your setup and give me a feedback on the performances ?

Hi Alexis,

Please try the images that I shared in the following thread: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1167173/sk-am62-some-question-about-chromium-and-gpu-integration/4395605#4395605. I also added instructions for how to launch QtWebengine.

Hi Krunal,

I tested your image with the command line:

./simplebrowser --platform eglfs --disable-gpu http://myserver/app

The animation is not showing any problem of refresh.

I'm mean that there is no horizontal blank line on the logo.

But the animation freeze some time, so the animation is not smoothly displayed.

The top command show 160% of usage with irix mode enable.

If I'm understood correctly le manual, it means that the 4 CPU cores are not overcharged because load can be up to 400% ?

Moreover the delay to display the web app is 24 secondes compare to 4second on a PC.

I also tested chromium from weston session and the issue is still there.

Could you confirm that you are still working on improving chromium performance ? Because we are currently blocked by this issue ?

If so when to you plan to provide more information ?

Regards,

Alexis.

Hi Alexis,

I believe François already reached out to you but I am working internally on the timelines. Chromium has known issues against our SDK and we are working towards a solution. I will keep François and you posted once I hear back from the team.

Hi Krunal,

Could you keep me in informed of your progess and as soon as you have a fix

Have a nice day.

Hi Alexis,

We are working towards a plan and I just wanted to confirm a couple of things:

1. What Chromium version are you interested in? Also, are you using the meta-browser layer with Dunfell or Kirkstone release?

2. Could you share your test with me again and steps for compiling/measuring performance? I would like us to have a baseline that we use for measuring performance delta.

Krunal

Hi Krunal,

1. I configured the local.conf file to add chromium-ozone-wayland in the dunfell release, we didn't go through kirkstone yet. :

IMAGE_INSTALL_append = " chromium-ozone-wayland"

The version of the package is: 75.0.3770.142-r0.arago0

Here is the content of my config:

$ cat configs/processor-sdk/processor-sdk-08.04.01.04-config.txt

2. I didn't create a specific test, I just display the CSS animation, refered as 1106.Test.zip in my previous post in the browser and check that it's displayed smoothly.

Could you tell me if you need more information ?

Regards,

Alexis.

Thanks Alexis! In general, do you have any hard requirements on the version number? I believe he head of the meta-browser points to version 109. The reason I ask is because I am trying to use the latest version for our internal testing and I was wondering if that is okay. Also, thanks for the application and I will share with our developers.

Krunal,

We have no requirements for the Chromium's version, but it must be compatible to dunfell then kirkstone.

The CSS animation is the above images spinning.
