Can't Android FVP use drm-hwcomposer instead ?

Not without kernel changes. See e.g.
https://www.spinics.net/lists/dri-devel/msg255883.html

Has this gotten better in the last year+ so you can now use
drm-hwcomposer?

I.e. can we now delete the fbdev driver?

Also, if we need to add more random fbdev ioctls to the drm fbdev
emulation, then let's do that. Not keep fbdev drivers on life support for
longer than necessary.

I wanted to fix this and started to look at it at one point,
however the required Android userspace build was a bit
intimidating to get going. I would be able to look into this
if a prebuilt Android for the emulation model was available.

Yours,
Linus Walleij
