Subject: RE: [PATCH 0/4] drm/fsl-dcu: add overlay and cursor plane support
Date: Wed, 7 Sep 2016 08:43:55 +0000 [thread overview]
Message-ID: <DB6PR0401MB2631D04399EE18A7686D5F62ECF80@DB6PR0401MB2631.eurprd04.prod.outlook.com> (raw)

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
