SYNOPSIS

int drm_fb_helper_init(struct drm_device * dev, struct drm_fb_helper * fb_helper, int crtc_count, int max_conn_count);

ARGUMENTS

dev

drm device

fb_helper

driver-allocated fbdev helper structure to initialize

crtc_count

maximum number of crtcs to support in this fbdev emulation

max_conn_count

max connector count

DESCRIPTION

This allocates the structures for the fbdev helper with the given limits. Note that this won't yet touch the hardware (through the driver interfaces) nor register the fbdev. This is only done in drm_fb_helper_initial_config to allow driver writes more control over the exact init sequence.

Drivers must set fb_helper->funcs before calling drm_fb_helper_initial_config.

RETURNS

Zero if everything went ok, nonzero otherwise.
