NAME¶
drm_fb_helper_init - initialize a drm_fb_helper structureSYNOPSIS¶
int
drm_fb_helper_init(struct drm_device * dev,
struct drm_fb_helper * fb_helper,
int crtc_count,
int max_conn_count);
ARGUMENTS¶
devdrm 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.AUTHORS¶
