Richard Purdie 0467d53017 bitbake: cooker/server: Fix up 100% CPU usage at idle
The recent inotify changes are causing a 100% cpu usage issue in the
idle handlers. To avoid this, we update the idle functions to optionally
report a float value which is the delay before the function needs to be
called again. 1 second is fine for the inotify handler, in reality its
more like 0.1s due to the default idle function sleep.

This reverts performance regressions of 1.5 minutes on a kernel build
and ~5-6 minutes on a image from scratch.

README

Poky
====

Poky is an integration of various components to form a complete prepackaged
build system and development environment. It features support for building
customised embedded device style images. There are reference demo images
featuring a X11/Matchbox/GTK themed UI called Sato. The system supports
cross-architecture application development using QEMU emulation and a
standalone toolchain and SDK with IDE integration.

Additional information on the specifics of hardware that Poky supports
is available in README.hardware. Further hardware support can easily be added
in the form of layers which extend the systems capabilities in a modular way.

As an integration layer Poky consists of several upstream projects such as 
BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information 
e.g. for the hardware support. Poky is in turn a component of the Yocto Project.

The Yocto Project has extensive documentation about the system including a 
reference manual which can be found at:
    http://yoctoproject.org/documentation

OpenEmbedded-Core is a layer containing the core metadata for current versions
of OpenEmbedded. It is distro-less (can build a functional image with
DISTRO = "nodistro") and contains only emulated machine support.

For information about OpenEmbedded, see the OpenEmbedded website:
    http://www.openembedded.org/

Where to Send Patches
=====================

As Poky is an integration repository (built using a tool called combo-layer),
patches against the various components should be sent to their respective
upstreams:

bitbake:
    Git repository: http://git.openembedded.org/bitbake/
    Mailing list: bitbake-devel@lists.openembedded.org

documentation:
    Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/
    Mailing list: yocto@yoctoproject.org

meta-yocto(-bsp):
    Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto(-bsp)
    Mailing list: poky@yoctoproject.org

Everything else should be sent to the OpenEmbedded Core mailing list.  If in
doubt, check the oe-core git repository for the content you intend to modify.
Before sending, be sure the patches apply cleanly to the current oe-core git
repository.

    Git repository: http://git.openembedded.org/openembedded-core/
    Mailing list: openembedded-core@lists.openembedded.org

Note: The scripts directory should be treated with extra care as it is a mix of
oe-core and poky-specific files.
