About the benchmark result for cog/wpewebkit and chromium-ozone-wayland on iMX8M Mini

[black53421]

Test Environment

• CPU run as 1.8GHz
• 2G RAM
• 1920x1080@60 MIPI-DSI to HDMI Display Output
• Yocto zeus (NXP's 5.4.70_2.3.0 Yocto BSP)
• iMX8MM only support wayland, so I test on wayland
• cog 0.10.0 + wpewebkit 2.32.3 + libwpe 0.10.0 + wepbackend-fdo 0.10 + proprietary Vivante driver
• chromium-ozone-wayland 83.0.4103.116

Benchmark Result

• JetStream1.1
• cog: 27.533
• chromium: 21.734
• JetStream2
• cog: 15.740
• chromium: 14.161
• MotionMark1.2
• cog: 1
• chromium: 5.52
• bmark
• cog: 119
• chromium: 156
• Unity3D Benchmark2015
• cog: 4381
• chromium: 7825
• Antutu HTML5
• cog: 8701
• chromium: 9293
• WebGL Aquarium
• cog: 5 fps (500 fishes)
• chromium: 13 fps (500 fishes)

Q&A

• Cog got better result on JavaScript, but it had poor performance for 3D rendering. Is there any way I can do to improve this?

Thank you

Here are some things you can try:

• Tune Weston repaint window
• Try with the open source graphics drivers (Mesa/Etnaviv)
• Try running Cog without Weston, so Cog runs directly over the framebuffer. For that enable the packageconfig option drm on cog and then start it with the -P drm parameter. Example: cog -P drm https://igalia.com Note: is likely this drm mode needs the open source drivers (Mesa/Etnaviv) to work.

Thanks for your information!

• About "Weston repaint window": I tried to set different value, but the FPS in WebGL Aquarium is not changed. I also tested in igalia FPGA meter, the FPS is 60.
• I will take a look on Etnaviv open source driver :)

I already compiled the open source graphic driver (mesa 21.0.3) in my Yocto environment and Cog could run on Weston successfully. However, I has some trouble in making Cog runs over the framebuffer. It show the following warning message when I use -P drm: (cog:1003): Cog-DRM-WARNING **: 03:33:52.139: failed to create framebuffer: No such file or directory

The following is the message while I set G_MESSAGES_DEBUG=all and LIBGL_DEBUG=verbose: (Weston is disabled while testing with drm.)

NOTE: I add "PACKAGECONFIG_append_pn-cog = " drm" in my local.conf to enable drm support.

Do I need modify the configuration for other recipes (such as mesa)?

Thanks.

[clopez]

Not sure what is happening and what leads to that error, but checking the log, it seems to me that it fails to open /dev/dri/card1 which seems to be the device with the render node associated (/dev/dri/renderD128) in this case. Can you double-check that this devices are with rw permissions ? Run: chmod 660 /dev/dri/*

[black53421]

I found someone had mentioned a similar issue #144 in Igalia/cog. After checking the mesa in GitLab, I found there is a patch for this issue. I could run Cog with -P drm parameter after apply this patch. Unfortunately, the screen only show garbage data, so I still investigate it. Do you have any idea for this?

NOTE: kmscube and glmark2 could work.

[gnulux]

@black53421 : I'm trying to build a Yocto image for imx8mp board . Would you please to share your local.conf which include mesa driver , cog + wayland ?

Thanks
