|
|
* VIU Handles the Pixel scanout and the basic Colorspace conversions
|
|
* We handle the following features :
|
|
*
|
|
* - OSD1 RGB565/RGB888/xRGB8888 scanout
|
|
* - RGB conversion to x/cb/cr
|
|
* - Progressive or Interlace buffer scanout
|
|
* - OSD1 Commit on Vsync
|
|
* - HDR OSD matrix for GXL/GXM
|
|
*
|
|
* What is missing :
|
|
*
|
|
* - BGR888/xBGR8888/BGRx8888/BGRx8888 modes
|
|
* - YUV4:2:2 Y0CbY1Cr scanout
|
|
* - Conversion to YUV 4:4:4 from 4:2:2 input
|
|
* - Colorkey Alpha matching
|
|
* - Big endian scanout
|
|
* - X/Y reverse scanout
|
|
* - Global alpha setup
|
|
* - OSD2 support, would need interlace switching on vsync
|
|
* - OSD1 full scaling to support TV overscan
