In order to extend and create more kernel recipes based on the
supported yocto kernel common routines need to be placed in
re-usable blocks.
To accomplish this meta/recipes-kernel/linux/linux-yocto_git.bb
is broken into three parts:
- meta/classes/kernel-yocto.bbclass: contains common routines
for checking out and configuring a yocto kernel git repository.
This should be inherited by recipes that need this functionality.
- meta/recipes-kernel/linux/linux-yocto.inc: Contains the machine
mappings, compatibility, build directives and common task
definitions for a yocto kernel based recipe. This inherits
kernel-yocto, and is the typical point of entry for other recipes.
- meta/recipes-kernel/linux/linuux-tools.inc: tasks and function definitions
for kernel recipes that want to build/export perf
It also updates the linux-yocto recipe to default to 2.6.37.
As part of the update to 2.6.37 the branch naming and conventions
have been modified to show inheritance, and be more generic.
For example:
master
meta
yocto/base
yocto/standard/arm_versatile_926ejs
yocto/standard/base
yocto/standard/beagleboard
yocto/standard/common_pc/atom-pc
yocto/standard/common_pc/base
yocto/standard/common_pc_64
yocto/standard/fsl-mpc8315e-rdb
yocto/standard/intel_atom_z530
yocto/standard/intel_core_qm57_pch
yocto/standard/mti_malta32_be
yocto/standard/preempt_rt/base
yocto/standard/preempt_rt/common_pc
yocto/standard/preempt_rt/common_pc_64
yocto/standard/preempt_rt/intel_atom_z530
yocto/standard/preempt_rt/intel_core_qm57_pch
yocto/standard/qemu_ppc32
yocto/standard/routerstationpro
In this structure:
master: tracks the mainline kernel
meta: meta information for the BSPs and kernel features
yocto/base: baseline kernel branch
yocto/standard/base: 'standard' kernel, contains features
and configs for all BSPs
yocto/standard/<machine>: represents a BSP with specific
features or configurations
The tools, tree and libc-headers have all been updated to
deal with this new structure. Also in addition to dealing with
the new structure, they continue to work with the existing
tree and will adapt at runtime to the differences.
The linux-yocto-stable_git.bb recipe continues to build the
2.6.34 based tree,and linux-yocto_git.bb builds 2.6.37. As
boards are enabled for the new kernel they will move from
-stable to the development kernel. As of now, only the
emulated targets have moved to 2.6.37-rcX

Comments covered some minor points. We did remove the "Creating
a Transition Kernel Layer" section however.

Cyril submitted a patch via email form for several spelling corrections. The master docs, however, are not up-to-date with what I have on my contrib area. Many of Cyril's corrections were already addressed. A few were not and I have updated them here with this commit.

There is inconsistent use of how BitBake is spelled. Sometimes it uses no capitalization, just a leading "B", or "BitBake". I looked at the BitBake manual and it seems that "BitBake" is the correct way to refer to it.

I pulled the openembedded mailing list information and provided information for yocto@yoctoproject.org, yocto-announce@yoctoproject.org, and poky@yoctoproject.org. I also updated the IRC section to include both #poky and #yocto channels.

Feedback indicated by Dave suggested getting rid of this. So I commented out the text around it and modified the reminder text so it did not reference a figure.

This is inline with how the other docs are built. kernel-manual.xml
is called by xsltproc from the Makefile.

I made this file similar to the bsp.xml file so that it would build into
a PDF file. It was throwing an error because of the imagedata tag
that was up front.

Code now calls a new file called kernel-manual.xml that in turn
includes the yocto-project-kernel-manual.xml file. This is in line
with how the other docs are built.

this section is based on an email that Bruce Ashfield sent me. It replaces
what was in there in the form of sub-sections for creating a new BSP,
cloning one and bsp bootstrapping.
I needed more demarcation for these section titles. They were not visually
different enough.

This is the first draft of the Yocto Project Kernel manual. The
manual consists of two sections: concepts and a practical section that
has examples. It is based of Bruce Ashfield's kernel theory paper.
This first draft has been re-written and organized through the
concepts section. The remainder was just placed in as-is due to
time constraints for getting some kernel documentation up on the website.
The manual still needs scrubbing and organization in the latter half.
