After building mir in a s390x ubuntu OS following the instructions in this link I get the following output issuing the miral-shell command:

Any advises in how to get the miral shell running?

Thanks in advance.

s390x? That is unusual, it will be good to hear how well things work on that architecture.

Anyway, it looks like the problem is failing to find a cursor theme installed. I think that apt install dmz-cursor-theme should resolve that for you. If you don't have cursors installed, then you might well be missing fonts. So I'd recommend something like:

apt install dmz-cursor-theme fonts-freefont-ttf fonts-font-awesome

Good luck!

m4rk0Kruz commented 6 months ago

s390x every time is getting more support but unfortunately is still a long way to be completely stable... After isntalling the fonts and cursors, this time shows a adifferent error:

Hopefully it can be solved installing a compatible component...

AlanGriffiths commented 6 months ago

Can you provide a bit more information on the environment you are running in?

The "Selected display driver: mir:x11" indicates Mir is trying to run hosted by some existing X11 server you are using, is that GNOME?

The recent Trying to create SHM buffer with unsupported pixel format error sounds like graphics hardware behaving in a way we didn't anticipate. Can you...

snap install graphics-test-tools
graphics-test-tools.drm-info

And post the output?

AlanGriffiths commented 6 months ago

Actually, there's probably a shortage of snaps packaged for s390x...

sudo apt install drm-info
drm_info
m4rk0Kruz commented 6 months ago

The output shows

drmGetDevices: No such file or directory

Checking the list of defined devices, seems that there is no video device defined in the system, so, that might be the reason of the problem...

I'm new in the Linux world, so, I'm not sure how is the current X11 configuration, but definetly GNOME is not installed since it is the server version of Ubuntu, besides, the s390x runs in a hardware that doesnt have hardware dedicated for graphics. I will have to check the documentation to know if I can define video devices directly in ubuntu or if it will be needed a configuration at hardware level...

Thanks a lot for the provided support.

AlanGriffiths commented 6 months ago

This seems like an odd system (no display hardware) to use Mir on. And running Mir on an X11 host is primarily for testing. What are you hoping to achieve?

RAOF commented 6 months ago

So, at least one of the problems here is going to be that s390x is a big-endian architecture, and this affects the memory-layout of pixel data in a way that we don't support.

I think this is actually the only place this applies; if you wanted to check you could remove the #ifdef and keep only the little-endian branch. Colours would be wrong, but you could see if the rest of Mir works.
