[PATCH 06/11] drm: Add multi buffer plane pixel formats

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Seung-Woo Kim <sw0312.kim@xxxxxxxxxxx>

Multi buffer plane pixel format has seperated memory spaces for each
plane. For example, NV12M has Y plane and CbCr plane and these are in
non contiguous memory region. Compared with NV12, NV12M's memory shape
is like following.
NV12  : ______(Y)(CbCr)_______
NV12M : __(Y)_ ..... _(CbCr)__
