Cover letter [Buildroot] [RFC v3 00/30] Add per-package staging feature

Dear Fabio Porcedda,

Could you give some hints about the performance impact of those copies of the staging directory? Does it continue to make the top-level parallel build thing useful?

IMHO the per-package staging feature is useful even without taking in consideration the top-level parallel build, the unspecified optional dependency issue are not common, they can generate build faulres or just binary with unexpected behavior.

Yes, correct, this is indeed another benefit of this approach.

Preferably something with a fairly deep dependency tree, i.e lots of small packages that depend on each other. A X.org stack + gtk2 would be a good example.

The most complete selection of package that i've tested is the defconfig + allyespacakgeconfig (693 targets), i've tried to enable a wider range of packages, defconfig + glibc + allyespackageconfig but even without using the pps they fail to build.
So i will provide build times of the configuration defconfig + allyespackageconfig.

Ok.

If you provide a defconfig on the release 2015.02, i can try to build that.

Something like:

BR2_arm=y
BR2_TOOLCHAIN_BUILDROOT_LARGEFILE=y
BR2_TOOLCHAIN_BUILDROOT_INET_IPV6=y
BR2_TOOLCHAIN_BUILDROOT_INET_RPC=y
BR2_TOOLCHAIN_BUILDROOT_LOCALE=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
BR2_PACKAGE_XORG7=y
BR2_PACKAGE_XSERVER_XORG_SERVER=y
BR2_PACKAGE_LIBGTK3=y

Thanks!

Thomas
