The raspberrypi3-64.conf file has the line:

MACHINE_FEATURES_append = " vc4graphics"

I assume this means it is using vc4? There is no use of "userland" in my 
build/conf
directory. I am fairly new to Yocto, so I am wondering if there is a definitive 
way to 
tell whether the vc4 graphics were used to build the image.

[yocto] Problems running image in qemu (x86)

[Alex J Lennon]

Hi,

I'm bringing the Mono build up to date in the meta-mono layer and ran
into a problem with my testing.

I generally target QEMU, e.g. qemux86, build a core-image-sato based
Mono test image and run up with 'runqemu qemux86'

It's a remote build system so I am SSH'd in with VNC port forwarding and
I view the QEMU box running with a TightVNC client.

This has worked well for a long time, and still works fine with the
current krogoth branch.

I have just built against master though and am seeing screen corruption.

e.g. https://postimg.org/image/xjcdybdul

Can anybody tell me what's changed?

Thanks,

Alex

Hi,

Are you using vc4 as graphics, or are you using the default userland?
If you want graphics with 64 bits, you need to use vc4.

Cheers,
Herve

Readding the mailing list.

what you have is exactly what I had when I submitted the port to
meta-raspberrypi. Haven;t had a chance to revisit it. but this could
be related to device tree files we are using here. I have had reports
from other devs of having been able to boot into graphics using older
kernels but I never got
that far myself.
