I have had problems getting good download performance when accessing the

decided to create a copy of the
kernel repository locally and use that for my builds.
There are instructions on how to create a local repository in the Yocto
manuals, but those are more complex than I needed. (I don't plan on checking
anything into the repository.)
The below is a simpler way of creating and using the repository.
I'm publishing this because my search though the Yocto/OE/Angstrom yielded only
the more complicated or incomplete methods.
// First set up local kernel repository
mkdir ~/ksrc3-8
cd ~/ksrc3-8
git clone --bare
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
stable-work-bare.git
// Then modify the kernel recipe to use the local repository instead of the the
one at kernel.org.
// The beaglebone recipe for the 3.8 kernel is at...
setup-scripts/sources/meta-beagleboard/common-bsp/recipes-kernel/linux/linux-mainline_3.8.bb
// Replace the file's SRC_URI with one that points to your local repository.
#SRC_URI =
"git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git;branch=linux-3.8.y"
SRC_URI = "git:///home/Bob/ksrc3-8/stable-work-bare.git;branch=linux-3.8.y"
IMO a much simpler (and certainly less invasive) way is to just
use your own local source mirrors. Add these lines to your local.conf:
SOURCE_MIRROR_URL = "file:///some-mirror-directory/"
INHERIT += "own-mirrors "
BB_GENERATE_MIRROR_TARBALLS ?= "1"
Once the git repository has been downloaded, it will be packed up in a
tarball, e.g.
git2_git.kernel.org.pub.scm.linux.kernel.git.stable.linux-stable.git.tar.gz
If you then put this file into your SOURCE_MIRROR, the next time bitbake will
fetch from there [first]. It's even smart enough that if you need a revision
which is not in the tarball, it will update the git repository and rebuild the
tarball, which you can then move to your mirror.
Fast access, no messing with source recipes!
