* This is good to go into the master branch
* Would be nice if this can be back ported onto dora.
[Franklin] I'm assuming you really need this in dora correct? The reason I
say this is currently your patches as is won't do anything for you since newer
versions of the wayland recipes exist which means those newer versions will
be used not this older version. If you really need this in master then I would
suggest updating these patches against Wayland 1.4/1.5. I have pending
patches for Wayland 1.5 so if it is accepted I would rebase those patches off
of that version.
I actually meant daisy and not dora.
Yes, I agree but when its intended to be used I was thinking about setting the
PREFERRED_PROVIDER.
[Franklin] Due to issues with Qt 5 we need Wayland 1.5 so going back to 1.3
won't be an option in master atleast for am57x. So unless you absolutely
must use Wayland 1.3 I would recommend at least in Arago master updating to
the newer version of wayland so we can stay on the same version.
Franklin,
My understanding is that GLSDK team has done extensive testing and validation
of the patches against 1.3 and up-porting them now to either 1.4 or 1.5 is out
of the question due to time constraints.
But I would agree that from maintenance point of view it would be much more
desirable to have a single version used by all our products.
To add, migrating from one version of Wayland to another also has a lot
of underlying dependencies especially when you consider hardware
accelerated graphics via DRM. So there are lot of other components that
we have to add support for and you cannot consider Wayland/Weston as a
lone component. GLSDK was earlier on Wayland 1.0.6 and then moved to
1.3.0, there are dependencies such as SGX DDK and DRM (both userspace
and kernel) that have to move together.
If you are only considering minimal wayland support - that is fbdev, and
not using multiple display/desktop sharing and support for EGL etc. then
migration is kind of easier.
This will be useful for those customers who are interested in these
other features and using DRM.
