Yes, and it raises a few more ;)
pls see at end of email: DRI state with playback

so: plane #37 is where video is drawing plane #43 is GUI/OSD

Ok, this seems to be the base plane.
plane[37]: Esmart0-win0 crtc=(null)
crtc=null? Did you capture the state without a video playing? Otherwise I would expect a crtc associated here.
Indeed. This was from player sitting in UI (no playback). Pls see at bottom of email state with video playback (it has crtc=video_port0)
fb=0 crtc-pos=1920x1080+0+0 src-pos=1920.000000x1080.000000+0.000000+0.000000 rotation=1 normalized-zpos=0 color-encoding=ITU-R BT.601 YCbCr color-range=YCbCr limited rangeplane[43]: Cluster0-win0 crtc=(null)
This plane is selected for OSD by your application. The cluster windows can't show a regular linear framebuffer, they can only do AFBC. You'll see that in modetest:
in_formats blob decoded: XR24: ARM_BLOCK_SIZE=16x16, ARM_BLOCK_SIZE=16x16,MODE=SPARSE ARM_BLOCK_SIZE=16x16,MODE=YTR ARM_BLOCK_SIZE=16x16,MODE=CBR ARM_BLOCK_SIZE=16x16,MODE=YTR|SPARSE ARM_BLOCK_SIZE=16x16,MODE=SPARSE|CBR ARM_BLOCK_SIZE=16x16,MODE=YTR|CBR ARM_BLOCK_SIZE=16x16,MODE=YTR|SPARSE|CBR ARM_BLOCK_SIZE=16x16,MODE=YTR|SPLIT|SPARSE ...
The other windows show "XR24: LINEAR" here. Does your application use the GPU to render the OSD?
Yes.
Otherwise I doubt your application can handle this format, so it should not use this layer.
fb=0 crtc-pos=0x0+0+0 src-pos=0.000000x0.000000+0.000000+0.000000 rotation=1 normalized-zpos=0I would be interested in this output when the player is actually playing something.
Pls see at bottom.
This normalized-zpos puzzles me a bit.
I'm not surprised :-). You are puzzled probably because rk35xx current VOP2 code requires - from me - to force Z-position = 0 in Qt if I want to have GUI visible on screen. Without this screen is black. This seems to be i think - another issue to resolve (no any other SoC requires this....). I'm not sure where issue is - but as i need to do this only on VOP2 - i think there is somewhere something not right in VOP2 code.
Normally it should be unique over all enabled planes for a CRTC. Maybe 0 is ok here because it's currently not associated to any CRTC.
It is because of me setting it to 0 (see explanations above)
