Hello,

Sascha Hauer a ?crit :

The following series adds i.MX51 framebuffer support based on the IPUv3. It
is not perfect but I decided it is good enough to open it for a wider audience
and collect first reviews. I tested this on a babbage board using both outputs
(VGA/DVI) with different resolutions up to 1680x1050 and different colour depths.
I also tested it on one custom board using a fixed display setting.

This driver is also working fine for me on a custom i.MX51 board with a
800x480 18 bits TFT LCD (16bpp mode).

The only strange thing I noticed was a kind of uggly sprite/artefact
(32x32, I would say) appearing at the same time as the Linux console. I
think it may be related to a hardware cursor badly (?) initialised, but
I didn't find a fix yet.
It disappears when I launch a graphical application (Qt or SDL).

It may be the penguin, but I remember a similar report also talkling
about hardware cursors. I can't reproduce this. You could search for
cursor in the IPU section of the manual and play with the corresponding
registers.

We see this too, but only when increasing resolution from the kernel 
default. We get a yellow square appear in the lower right quadrant of 
the display.
