Hello all.
Since the release of kernel 6.0.X, which has been announced the enabling
of v3d to support hard acceleration in RPi4, I've tried tested/daily
image from raspi.debian.net, the latest test, I installed Gnome, and I
can see from Settings/About, that 'v3d' is the GPU driver. (I've attach
the screenshot).
That initial support is out of the box, after I asked in
#debian-raspberrypi on IRC, they have suggested me to follow the link of
https://melissawen.github.io/blog/2022/11/10/v3d-in-the-mainline .
I am not sure if recompiling the kernel is necessary, especially, I am
getting some indicate that there is v3d, so I just added the
'device_tree=bcm2711-rpi-4-b.dtb' to config.txt, but nothing has been
changed.
There are problems with firefox and chromium when launching them and
window/maximizing/... .
Here some logs when I run firefox-esr from the command line: (The
following results whether that line is added or not, no difference)
$ firefox-esr

I wish debian to get the fully 3d supported as it's already in the kernel.
Thank you.
