BTW I think chip manuals all say that the chip supports NxN resolution in DE2 chapter, e.g. the V3 datasheet says DE2 "Output size up to 1024x1024".

My information comes from the BSP driver[0]: static const int sun8iw20_de_scale_line_buffer[] = { /* DISP0 */ 2048, /* DISP1 */ 1024, }; It looks like the value returned from de_feat_get_scale_linebuf() may be used for RGB as well, if scaling is enabled. This appears to be the "format == 3" case in de_rtmx_get_coarse_fac[1]. On the other hand, the code for V3 has specific code for the RGB limit[2]. Is there some test I can do on D1 to see what the right value for RGB is?

It's part of libdrm. In general, you want to make plane wider than scanline and then scale it down. Obviously you want to test this once with RGB and once with YUV format. This is all done with "modetest -P".

Accrording the SDK from Allwinner, the scanline value of yuv and rgb for V3s are both 1024. The is also the same for mixer 1 of D1. Currently the scanline value of rgb is hardcoded to 2048 for all SOCs. Change the scanline_yuv property of V3s to 1024. Add the scanline_rgb property to the mixer config and replace the hardcoded value with it before scaling.
