The drm_format_info.cpp[3] unit is BytePerPlane, when we add define
10bit YUV format, here have some problem.
So we change cpp to bpp, use unit BitPerPlane to describe the data
format.

Whatever the layout you have for these (it's not really defined in
your patch here down to the level of detail we want) I think this
should be described with the block_h/w and char_per_block
functionality. Not by extending the legacy and depcrecated cpp
somehow.

Hi Daniel,

It seems the char_per_block and block_h/w can't describing the following
data format:

/*
Â* 2x2 subsampled Cr:Cb plane 10 bits per channel
Â* index 0 = Y plane, [9:0]
Â* index 1 = Cr:Cb plane, [19:0] Cr:x:Cb:x [19:0]
Â*/
In that case, you can follow the same route which we took for
describing formats like DRM_FORMAT_VUY101010, DRM_FORMAT_YUV420_8BIT,
DRM_FORMAT_YUV420_10BIT ie define cpp as {0, 0, 0} and in your
vendor driver have a function similar to malidp_format_get_bpp().

It does not look nice to me to change all the formats described
in cpp to bpp for just one vendor specific format.

Thanks,
Ayan

Hi Ayan and Daniel.

ÂÂÂ thanks for your suggestion, i have send new pathes for rockchip 10bit yuv format support.
