Upgrade to Linux 4.14

[bamarni]

This upgrades to Linux 4.14, I'm not pushing this directly to master as I just have made a build locally without releasing for now.

How can I upgrade my box to test it ?

[aleroot]

everything seems to be fine, I think that it should be merged and allow the pi64-update tool to perform the upgrade automatically

[aleroot]

I think that we should upgrade to 4.14.11 and release to users as soon as possible given the current meltdown security issue ...

[romen]

Not that updating the kernel is not important anyway, but regarding Meltdown and Spectre, they don't affect the SoC used in any of the Raspberry Pi (including 3).

Can this be merged then? what is blocking this merge?

It has been a long time since last upgrade is released. I have tried to build the 4.14 kernel, but I don't know how to deal with the "firmware". I wonder if this repository is maintained?

If there will be no update: https://github.com/Debian/raspi3-image-spec
Still trying to figure out how to do a smoth kernel upgrade without reinstalling though

--EDIT-- those are the bits from the build script but you have to dist-upgrade to buster first and then cross fingers it will reboot :)

TODO: install raspi3-firmware and linux-image-arm64 from buster once they

migrated in sufficiently recent versions.

• chroot: root-fs
  shell: |
  echo 'deb http://deb.debian.org/debian unstable main contrib non-free' >> /etc/apt/sources.list
  echo 'APT::Default-Release "buster";' > /etc/apt/apt.conf.d/08default-release
  apt-get update
  apt-get -y --no-show-progress -t unstable install raspi3-firmware linux-image-arm64

Would it be possible to have instructions on how to upgrade to the 4.14 kernels?
Please help a noob :)

I mean using this: cc3bfd2

I'm not sure what to do with that.

@Xnyle
I have upgraded to the buster,and tried the command you given, but the installation of raspi3-firmware failed, because of the missing of /boot/firmware
Would you please tell me how to deal with it ?

Any news here, @bamarni?

I finally successfully build the Linu.tar.gz with the 4.14 branch ,but the onboard WiFi doesn't work. By the way , it keeps showing the under-voltage warning which didn't occurred on 4.11. Sometime the shell froze when I use cd command,I have to type Ctrl+C to continue my work. In one word, it is not a daily usable version now,I had rolled back to the 4.11 now, it seems the 4.14 still needs some work...
