Hi all,

Not sure if this has been covered elsewhere. I'm working on a sama5d2 based device where the kernel supported by the hardware vendor is 4.4. 
Any drivers we develop and test are based on this version of the kernel. 
Do the kernel maintainers accept drivers for older (but maintained) versions of the kernel? Is there some general policy regarding this or is it a question that I need to ask the maintainer of the subsystem that the driver belongs to?

Thanks.

DJ

Nope, for the simple reason that we can't go back in time and add them to old releases :)

Have you read the stable_kernel_rules.txt file in the Documentation directory for what type of patch is allowed in the stable kernel releases?  It should answer this question. Also look at the development_process/ "book" in the tree, that should help out.

In short, you always have to add new features to the latest development verison of the kernel.

hope this helps,

Hi All,

Is the following challenge working,

http://eudyptula-challenge.org/. I tried mailing little at eudyptula-challenge.org 2 to 3 times but there was no reply.

Other than the instructions mentioned in http://eudyptula-challenge.org, is there anything that i am missing?

You're missing the fact that the challenge has been overwhelmed by entrants,
and that it can take as much as a few weeks for them to get around to dealing
with your submission.

Little also announced some time back that the challenge would be
closed for new entrants after 20k entrants (at that point there were
19k), so it might be closed already?

But yeah, be patient, sometimes little is busy - but he'll get back to
you eventually.
