RE: fb driver for logiCVC

[Davor Joja]

Hello Bruno,

Thank you for the answer!

I did not send it before to linux-fbdev since I thought that it is more likely to get answer at linux-kernel list.
Will do that from now.

Unfortunately, I have this driver on mentioned git only for few weeks, so there is no usable history.
Since this is new driver, tested and functional (on kernel 3.8), without git history as stated above, do you have idea how to break it to smaller pieces? I can only think off as one big patch against 3.8.x version.
That could be accepted for new driver?

You are right about git, it is not organized in standard way.
It is created for our customers to easily get latest drivers for Xylon IP cores because they already know what they need and in which folder to search. Maybe this was not good idea to send that git link for review. Will stitch to patches in the future, even for new drivers.

Regards,
Davor

You should also send it to linux-fbdev (CCed) so interested people have a better chance of seeing it (and quoting previous mail below).

If you have a git tree with history it might be nice. Otherwise it's easier to review if you can split the big-patch into multiple incremental parts adding some functionality each (that incremental nature would also be expected from a git tree).

Your tree at https://github.com/logicbricks/linux_kernel looks weird, you seem to have imported just the subfolders of kernel tree you worked on instead of cloning e.g. v3.8 release and applying your driver on top of it. This way it's not possible to merge your tree and it's rather hard to find out what belongs to your driver or not.
