That will be a pretty big change.
I would suggest to look at the git-history, there you will find some
tasks that extend the supported pixelformats, so you will get an idea of
the files you need to touch. It is probably not necessary to implement
full-scale support, but it will still be a big 'patch'.
Can you use DSPF_A8 or DSPF_A4 instead?

Hello
How difficult will it be to add support for 4-bit greyscale to directfb?
I am somewhat familiar with the directfb architecture. I have already
implemented a systems driver that communicates with a custom lcd
driver. (Similar to frame buffer driver). But I am converting from
RGB16 to grey scale in the updateregion and flipregion functions and I
would like to remove this.
thanks
