# drm\_mode\_legacy\_fb\_format(9)

compute drm fourcc code from legacy description

## NAME

drm\_mode\_legacy\_fb\_format - compute drm fourcc code from legacy description

## SYNOPSIS

**uint32\_t drm\_mode\_legacy\_fb\_format(uint32\_t** *bpp***, uint32\_t** *depth***);**

## ARGUMENTS

*bpp*

bits per pixels

*depth*

bit depth per pixel

## DESCRIPTION

Computes a drm fourcc pixel format code for the given *bpp*/*depth* values. Useful in fbdev emulation code, since that deals in those values.
