Bug Description

Hi!

Would it be possible to apply these patches for the trusty kernel so that the next LTS would fully work on the new Haswell based Chromebooks (Acer C720, HP Chromebook 14) out of the box? Currently and without these patches e.g. touchpad doesn't work.

The patches apply cleanly against linux 3.12.0-7.15 in trusty. This would most likely also fix https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1257879.

No need to gather logs, it's just a request for new hardware enablement in the kernel. These patches have been submitted to upstream for merge, but haven't been merged yet to submaintainer tree and Linus tree.

As a general rule we will consider these requests but much prefer the code to have hit mainline before we do. This help keep our delta from upstream code to a minimum.

Some of these patches could apply cleaner onto 3.13 since larger changes were made since 3.12. I recently reworked some of those changes into a patch for those getting the c720(p) version working in 14.04. This patch(along with the first two listed above) together should patch c720(p) support into the 3.13 kernel without major changes to existing code. (Note I did not include others like the HP chromebook due to no experience testing. The original patches also do not support the c720p, which mine do. If this is to be seriously considered, I will make sure the other devices the above patches support are added into mine.)

Nevermind on the Hp chromebook 14. I don't have to add it in because it is already in the 3.13 kernel. These are the only patches that should be needed:

Is there a way someone could turn these into DKMS packages?

It's annoying to have to Hold the kernel image packages, and then manually patch the updates.
