x86 testing

x86 testing

[Gary Thomas]

I'm trying to track down some recent changes in the X server
(using the latest Poky/Yocto master).  I've had failures on
a number of the embedded targets I work with, so I thought
I'd give it a go on platforms with a larger base - x86 machines.

It used to be that I could run qemu and it would pop up a separate
window that emulated a display+keyboard+mouse.  That doesn't seem
to be the same now, or at least I don't see how to make it work.
Advice on this would be great as I need to test the "native" X
setup, not VNC connections.

I'd also be happy to try this on real hardware, e.g. my wife's
laptop, but I need some way to do that non-destructively.  Again,
pointers would be greatly appreciated.

Once I get this figured out, I'll disappear back down my embedded
rabbit hole...

Thanks

qemu-native was changed to not depend on SDL. Instead of opening its own
window, it now provides access via VNC.

If you want the old behavior back, you need to compile with (from Poky's
local.conf.sample):

# By default qemu will build with a builtin VNC server where graphical output can be
# seen. The two lines below enable the SDL backend too. By default libsdl-native will
# be built, if you want to use your host's libSDL instead of the minimal libsdl built
# by libsdl-native then uncomment the ASSUME_PROVIDED line below.
PACKAGECONFIG_append_pn-qemu-native = " sdl"
PACKAGECONFIG_append_pn-nativesdk-qemu = " sdl"
#ASSUME_PROVIDED += "libsdl-native"

For the guest OS it shouldn't make a difference whether qemu uses its
own window or VNC.

This is lacking a bit of detail ... What did you try and what failed?

Building a qemux86-64  (or qemux86) image and running it should certainly
work ("runqemu qemux86-64").

The hddimg is both an installer and a live image: in other words if you
build e.g. a x86-64 core-image-sato you can dd it to a USB disk and boot a
typical laptop from USB without installing anything on hard drive.

Still is the case if you have 'sdl' in qemu-native's PACKAGECONFIG.  See
the sample local.conf, this was a change in behaviour a year or so ago so
there's a chance your local.conf doesn't do this.

Build an image using ideally meta-intel's intel-corei7-64 (or core2-32)
machine and put the hddimg on a USB stick.  This can live boot from the
stick directly.
