NAME¶
struct_drm_fb_helper_funcs - driver callbacks for the fbdev emulation librarySYNOPSIS¶
struct drm_fb_helper_funcs { void (* gamma_set) (struct drm_crtc *crtc, u16 red, u16 green,u16 blue, int regno); void (* gamma_get) (struct drm_crtc *crtc, u16 *red, u16 *green,u16 *blue, int regno); int (* fb_probe) (struct drm_fb_helper *helper,struct drm_fb_helper_surface_size *sizes); bool (* initial_config) (struct drm_fb_helper *fb_helper,struct drm_fb_helper_crtc **crtcs,struct drm_display_mode **modes,bool *enabled, int width, int height); };
MEMBERS¶
gamma_setSet the given gamma lut register on the given crtc.
gamma_get
Read the given gamma lut register on the given crtc, used
to save the current lut when force-restoring the fbdev for e.g. kdbg.
fb_probe
Driver callback to allocate and initialize the fbdev info
structure. Furthermore it also needs to allocate the drm framebuffer used to
back the fbdev.
initial_config
Setup an initial fbdev display configuration
