bpp value to use for the framebuffer configuration
.RE
.SH "DESCRIPTION"
.PP
Scans the CRTCs and connectors and tries to put together an initial setup\&. At the moment, this is a cloned configuration across all heads with a new framebuffer object as the backing store\&.
.PP
Note that this also registers the fbdev and so allows userspace to call into the driver through the fbdev interfaces\&.
.PP
This function will call down into the \->fb_probe callback to let the driver allocate and initialize the fbdev info structure and the drm framebuffer used to back the fbdev\&.
\fBdrm_fb_helper_fill_var\fR
and
\fBdrm_fb_helper_fill_fix\fR
are provided as helpers to setup simple default values for the fbdev info structure\&.
.SH "RETURNS"
.PP
Zero if everything went ok, nonzero otherwise\&.
