Hello NXP Team,
We would like to use "scale" option for weston wayland display system on imx8mplus with wayland backend (drm-backeend does not support scale)
SW info : yocto 5.4.0 (dunfell)
We understand that the IMX8Mplus support included from the release 5.4.47 (27-nov-2020)
Also, The wayland and x11 backend support has been removed from the meta-freescale
https://github.com/Freescale/meta-freescale/commit/5afc3561a2203b21e238bdc5c8c0f4048625e8de#
please provide us the details
- how can re enable it, any issues using wayland backend ?
- or any other way to support scale option for weston
regards
nagendra
Amber,
The scale factor under [output] will scale the physical display, for example if I give scale=2, half of my display would be blank and left over part would be utilised to display the content
What I am looking is, for the logical scaling , for example, if scale=2 the wayland should be full screen with double the size of mouse pointer

I'm able to get the NXP OLED display to scale and rotate through settings in /etc/xdg/weston/weston.ini
Note: Scaling seems to be ignored unless I comment out
"use-g2d=1" in the [core] section
For the OLED I'm using the following in the weston.ini file to scale and rotate:

That is the same behavior I get if I do not comment out
"use-g2d=1"
in the [core] section.
After I comment it out, it works the way I would expect, with everything bigger on the screen.
Yes, I could get scale up with commenting use-g2d, thank you
may I know few details on it , is g2d is not required ? is it specific to IPU?

G2D is described in the i.MX Graphics User's Guide. Basically, you are telling Wayland not to use 2D GPU acceleration for Wayland compositor by commenting it out.
