[yocto] [meta-qt5] How to increase depth of qemuarm from bootargs?

[sujith h]

Hi all,

I am trying to build Qt5 from meta-qt5 ( master branch ) with poky( machine
is qemuarm). The qtbase is built successfully and is installed into
core-image-sato. When I run : runqemu qemuarm
I can see the matchbox window launched successfully.The qtbase is having
gles2 enabled in the PACKAGECONFIG and gl is removed from PACKAGECONFIG. In
mesa I have enabled gallium. I do see a problem when I try to run qtbase
opengl examples.The gui gets displayed. But the image(s) associated with it
never displays. For example lets say there is an example known as cube.
When I try to run cube ( with -platform xcb), I could see a black screen.
The cube image never comes. So my query is if it's possible to increase the
depth ( default used is 16 for qemuarm ) to 24 through bootargs? If so a
helping hand would be great. Let me know if more information is required
regarding my setup. I have poky + meta-qt5 + meta-oe + meta-ruby layers in
bblayers.conf.

Thanks,
Sujith H
