DRM_FRAMEBUFFER_INIT(9) DRM Core DRM_FRAMEBUFFER_INIT(9)

NAME

drm_framebuffer_init - initialize a framebuffer

SYNOPSIS

int drm_framebuffer_init(struct drm_device * dev, struct drm_framebuffer * fb, const struct drm_framebuffer_funcs * funcs);

ARGUMENTS

dev
DRM device
fb
framebuffer to be initialized
funcs
... with these functions

DESCRIPTION

Allocates an ID for the framebuffer's parent mode object, sets its mode functions & device file and adds it to the master fd list.

IMPORTANT

This functions publishes the fb and makes it available for concurrent access by other users. Which means by this point the fb _must_ be fully set up - since all the fb attributes are invariant over its lifetime, no further locking but only correct reference counting is required.

RETURNS

Zero on success, error code on failure.
