Hi,
  I am trying to port one of our LCD display frame
buffer driver to 2.6 kernel.
  The old 2.4 kernel had these functions defined in
fb_ops
    fb_open:    
    fb_release:

These 2 are still in 2.6, but they're optional.

    fb_get_fix: 
    fb_get_var:     

Gone.

    fb_set_var: 

The above is split into:

fb_check_var() - see if the requested var is compatible
                 and if not, round up to the next
                 legal value

fb_set_par()  - set the hardware based on the current
                var

    fb_get_cmap:

gone

    fb_set_cmap:

replaced by fb_setcolreg()

 

    fb_ioctl:   

optional.

Additional required ops for 2.6.

fb_imageblit - expand monochrome to color and/or
               expand 8-bit pseudocolor to color

Generic version for packed-pixel: cfb_imageblit

fb_fillrect - fill rectangular area with solid color

Generic version for packed-pixel: cfb_fillrect


fb_copyarea - copy rectangular area

Generic version for packed-pixel: cfb_copyarea

  But the latest 2.6 fb_ops has removed these and
there is entirely new set of functions. 
  I tried to go to list archives but I could not find
information. 
  What functions in 2.6 fb_ops should to used to
implement this old 2.4 set of functions?

Look at skeletonfb.c for comments.  The simplest
framebuffer driver you can start with is vfb.c
