how to enable logo

["ankur maheshwari" <ankur_maheshwari@procsys.com>]

hi,

I have written a framebuffer driver of my own, which is base on virtual
framebuffer driver (vfb.c).
After linux boot up I can see my framebuffer in /proc/fb as device 0

0 myfbdriver

I am working on 2.6.11 uclinux.
What I want to know is ----
what are the option I need to enable in menuconfig in 2.6 kernel for
displaying logo on bootup.


Currently I tried
Device Driver -> Character device -> Virtual Terminal
Device Driver -> Character device -> Serial Driver -> Support for console on
serial device.
Graphic support -> Support of frame buffer devices
Graphic support ->Console display driver support -> Frame buffer console
support
Graphic support ->Logo configuration -> Standard 224-color Linux logo.
and My framebuffer driver.


After boot linux when I do cat /dev/fb0, I get a logo on my hyperterminal.
But console remains blank, I copied other files (.ppm) on /dev/fb0 and its
getting written on /dev/fb0 but console remains blank.

Can anyone share basic steps for logo display on linux 2.6 ???

I observed that while boot up console gives print ....
Console: Dummy colour device 80x25 .....

later when fb driver get loaded, I get following prints
Console: switching to frame buffer device 80x30

I have given fix. params as 640x480 but even then it switchs to 80x30.

Can any one explain me what going wrong ???? I am not passing any command
line params at present also I am not using _setup for command line parsing,
is that must ??

One more observation I made when I enable support for logo16 or black&white
logo, my driver gets loaded after fbcon and other fb modules, so doing cat
/dev/fb0 does not show me anything.


thanks
Ankur
