1010636 - Create repositories for Nexus 4/5 prebuilt kernels for B2G

Status: RESOLVED FIXED

(Developer Services :: Mercurial: hg.mozilla.org, defect)

Description

[Jed Davis [:jld] ⟨⏰|UTC-7⟩ ⟦he/him⟧]

For bug 1010008 and bug 1010009, we need to fork the AOSP repositories for the Nexus 4 (mako) and Nexus 5 (hammerhead) prebuilt kernels.  If I understand correctly, we'll need repos on github.com/mozilla-b2g and mirrors on git.mozilla.org for Buildbot.

Original repos and suggested names:

device_lge_mako-kernel → https://android.googlesource.com/device/lge/mako-kernel
device_lge_hammerhead-kernel → https://android.googlesource.com/device/lge/hammerhead-kernel

I'm not sure if this is the right Product/Component for this bug; adjust if needed.

Repos on github.com/mozilla-b2g have been created. Mako-kernel has been mirrored, hammerhead-kernel has not. Github rejects files over 100mb and there are commits in mako-kernel over that limit.

It looks like that's because they have a bzip2ed copy of the unstripped ELF image, as well as the zImage (+ appended DTB).  But git-filter-branch exists, so this isn't an inherent problem.  The BoardConfig.mk refers to that file:

  PDK_PLATFORM_ZIP_PRODUCT_BINARIES := device/lge/hammerhead-kernel/vmlinux.bz2

Do we need this for FxOS?  And, if so, do we need the debug sections?

I don't think we need vmlinux.bz2. If you can get that filtered out, feel free to push it over to the github mirror. You should have access.

Done.  I've only pushed the altered version of the android-4.4.2_r1 tag, not the other ones, but they're easy enough to add if/when we need them.
