Hello,
I was wondering if the ypan et al. options to the VESA framebuffer
device are broken in the 2.5 series.
Looking at the source, it seems that var.accel_flags is left
uninitialized in struct fb_var_screeninfo, in my setup accel_flags has
a value of 0. This in turn causes the scrollmode to be set to
SCROLL_REDRAW in fbcon_init(). Now in updatescrollmode() the
expression (p->scrollmode & __SCROLL_YFIXED) always evaluates to true,
and the scrollmode is never changed to ypan.
Am I missing something here? Can anyone confirm that ypan is actually
working with vesafb (i.e. is actually calling vesafb_pan_display)?
Cheers,
Alex
