Ok, i did copy the cfb_ functions to the driver, it works better (the
box does not hang anymore), the console apprently works (the cursor
blinks in the right place, and it could type stuff, switch VT and
shutdown the box) but there is nothing else written.

BTW, what is the difference between the full cursor and the underline
one ?

The block cursor most probably comes from fbcon's software cursor, the
underline is probably your hardware's?

Mmm, maybe the other way around ? i get block cursor with the old
accelerated pm3fb, and since i did enter no acceleration whatsoever yet
in the new driver, i don't believe it can be using the hardware cursor.

The fbcon software cursor is always a block cursor, well at least before
the latest patch James posted.  The newest patch should give you an
underline cursor by default.

Anyway, here are the two Oops :

I don't believe the result of running ksymoops on these are valid, i
will have to reboot in the 2.5.44 kernel for it.

If you did not define fb_set_var at all, then info->disp.dispsw must
point to valid console drawing hooks before you register the
framebuffer.  (Actually, all fields in struct display must be valid
before you register the framebuffer)

Mmm, still need to check those.

Your oops tracing points to fbcon_cursor as the culprit.  If
dispsw->cursor is NULL, then you must have a valid dispsw->revc.

There where two oops, the first in fbcon_setup, and the second in
fbcon_cursor, i think i will be looking in the first oops first.

Might as well try to port your driver using the latest fbdev patch
posted by James, hopefully, this is the last major change.  This should
give you less things to worry about.

Well, yes, i was going to donwload the BK tree, but james was speaking
about a 2.5.45 diff, which was finally not the right one.

I downloaded the patch 12 hours ago and actually ported a driver to
that.  So unless James changed it again, it should be the right one.
