Did you test this by yourself? Also, please make YUV scanline > change separate patch with fixes tag. Here is the code about scanline config for V3s: https://github.com/Tina-Linux/tina-v3s-linux-4.9/blob/master/drivers/video/fbdev/sunxi/disp2/disp/de/lowlevel_sun8iw8/de_feat.c#L55 https://github.com/Tina-Linux/tina-v3s-linux-4.9/blob/master/drivers/video/fbdev/sunxi/disp2/disp/de/lowlevel_sun8iw8/de_rtmx.c#L1212 And here is for D1: https://gitlab.com/weidongshan/tina-d1-h/-/blob/main/lichee/linux-5.4/drivers/video/fbdev/sunxi/disp2/disp/de/lowlevel_v2x/de_feat.c#L182 https://gitlab.com/weidongshan/tina-d1-h/-/blob/main/lichee/linux-5.4/drivers/video/fbdev/sunxi/disp2/disp/de/lowlevel_v2x/de_rtmx.c#L1588 I was tested it on V3s. Without this patch, the plane will not display correctly if src_w large than 1024, for both YUV and RGB. I don't have a device with D1, so D1 is not tested. But according to the SDK code of D1, the scanline value of mixer1 is 1024. I'm new to submitting patches, So may I ask a question? If there is no problem with this patch, what I need to do is to send new patches as you suggested? Best regards, Genfu Pan
