Hi All,
As some of the LayerManagerControl commands do not work when same surface is attached to two layers.
Following command hangs and do not come out as expected. I tried to check where it is hanging using GDB. Is this gives some hit on issue and resolution? Please suggest if you have any pointers.
LayerManagerControl get scene
root at linux1:~# gdb -p 916

Hi Emre,
Could you please suggest on this blocking behavior of LayerManagerControl with multi screen/layer?
Thank You.

Hi Emre Ucan,
Thanks a lot for your quick response. I am able to show same surface on two layers now. I have taken following two commit to weston 1.11.0. Attached here same as patch to weston 1.11.0.
"5e8d55da698e58"
"67bd21232fa549"
However if I use any of the below commands to analyze then it is not exiting and I need to prress "CTRl+C" to come out from command. Do you know if this is the normal behavior or some fix is available for this ?
root at linux-a1 :~# LayerManagerControl analyze surface 10

- counters: frame=0, draw=0, update=0
^C
Also following commands worked successfully.
LayerManagerControl get screen 0
LayerManagerControl get layer 2000
LayerManagerControl get layers
LayerManagerControl get surfaces
I used following commands to setup and test
export XDG_RUNTIME_DIR=/var/run/root/1000
LayerManagerControl create layer 1000 400 480
LayerManagerControl set layer 1000 visibility 1
LayerManagerControl set layer 1000 destination region 0 0 400 480
LayerManagerControl create layer 2000 400 480
LayerManagerControl set layer 2000 visibility 1
LayerManagerControl set layer 2000 destination region 400 0 400 480
LayerManagerControl set screen 0 render order 1000,2000
EGLWLMockNavigation &
LayerManagerControl add surface 10 to layer 1000
LayerManagerControl add surface 10 to layer 2000
LayerManagerControl set surface 10 visibility 1
LayerManagerControl set surface 10 source region 0 0 800 480
LayerManagerControl set surface 10 destination region 0 0 400 480

Subject: Same ilm surface on multiple layer support
+Subject
Dear All,
We are facing issue when we are trying to add same surface to multiple layers. When we try to attach surface to another layer, it is getting detached from the earlier layer.
We are using wayland/weston/wayland-ivi-extension 1.11.0 with drm-backend on TI's Soc.
Could anyone know if this is the limitation of ILM 1.11.0 ? Is this fixed in newer version and can it be ported to 1.11.0 ? or Is there any other way to show same surface on multiple layers?
I see it was the limitation with wayland-ivi-extesnion 1.9.0 as below [1].
"Currently 1 layer can be only on 1 screen, and 1 surface can be only on 1 layer,
we are planning to relax this limitation And allow 1 surface to be on many layers but we would need to break the ABI and change the
ivi-controller protocol."

Thanking you in advance.
Best Regards,
Vikash
