XWayland on Xorg server 1.15

[Quentin Glidic]

Hello guys,

I rebased the xwayland-1.12 branch of xorg-server on top of the current 
git master (which is the 1.15 dev version IIUC).

You can find it here:
http://git.sardemff7.net/wayland/xorg-server/log/?h=xwayland-1.15

I also updated the Intel and wlshm DDXs to build and run against it.
http://git.sardemff7.net/wayland/xf86-video-intel/log/?h=xwayland
http://git.sardemff7.net/wayland/xf86-video-wlshm/

They are just *rebased* branches, I am no X11 expert, and I simply hope 
I understood the parts right. It was not a big deal so there is no harm 
is just throwing them away if they are not relevant any more.


The old segfault of XWM is still there though.

The proposed semi-patch from Tiago was pushed here for testers:
http://git.sardemff7.net/wayland/weston/log/?h=wip/xwayland


The current state in my setup is:
Intel DDX works with Weston X11 backend. It does not with the DRM 
backend (“Failed to auth drm fd”). SNA is not supported.
wlshm DDX just render a black area for X clients.



Now, what is needed to get the whole thing right?
Tiago had some work on XWayland/XWM to make it better, and I do not 
remember which parts of the stack it touched, so I will consider it 
touches the Xorg server and the Weston XWM.


As a short-term goal, I think pushing the temporary fix is a good idea. 
That would let some more people testing it, and hopefully finding bugs.
Another thing to do is to rebase other DDXs, it should be quite easy and 
would make everyone up-to-date for the X server part.
Regarding the Intel DDX, SNA support should be fairly easy. I am not 
sure it is worth it, but it deserve a quick test, IMO.


As a long-term goal, we should rebase Tiago’s work on top on these new 
branches, if relevant. I can help a bit on this topic, but I am no X 
expert, so I may be useless here.


Tiago, can you point me to your XWM work (git branch, patches on the ML) 
and possibly tell me what is needed to do on that, or if we should start 
for scratch (again? :-) ).

Cheers,
