* 闫孝军反馈“4.19内核里面没这个format，要从linux 主线 5.2 以后里面反向porting 回来。4.19和5.2差别很大。
|
||
* 反向porting有很多冲突要解决”，所以从上层HWC模块去规避这个问题，HWC实现如下：
|
||
* 1.格式转换：
|
||
* DRM_FORMAT_YUV420_10BIT => DRM_FORMAT_NV12_10
|
||
* DRM_FORMAT_YUV420_8BIT => DRM_FORMAT_NV12
|
||
* DRM_FORMAT_YUYV => DRM_FORMAT_NV16
|
||
*
|
||
* 2.Byte Stride 转换：
|
||
* DRM_FORMAT_NV12_10 / DRM_FORMAT_NV12:
|
||
* Byte stride = Byte stride / 1.5
|
||
*
|
||
* DRM_FORMAT_NV16:
|
||
* Byte stride = Byte stride / 2
|
||
*
|
||
* 按上述实现，可以在当前版本保证视频送显正常，提供开关 WORKROUND_FOR_VOP2_DRIVER
