SubjectRE: [PATCH 0/4] drm/fsl-dcu: add overlay and cursor plane support
Date
Hi Stefan,

I had tested the patches on LS1021A-TWR board using drmlib.

Like set three overlays:
root@ls1021atwr:~# ./modetest -P 39:900x100+10+10@RG24 -P 39:200x200+300+0@RG24 -P 39:200x200+400+300@RG24

How did you test the overlays and cursor layer, I mean I see you using x-window like thing in the video.

Best Regards,
Meng
