RFC V2:
o Use VIRTUAL-RUNTIME_keymaps as suggested by Martin Jansa
o Drop poky-common abstraction as suggested by Richard Purdie in
favor of POKY_DEFAULT_EXTRA_R* variables.
Poky-tiny defines a new distro policy for building tiny Linux images.
Rather than create new image tasks and recipes, it reuses existing ones,
modifying them as necessary. I believe it defines policy appropriate for
the distribution, but I'd welcome feedback regarding the distro/image split.
Please see th poky-tiny commit log for details on the policy goals.
In its current form, poky-tiny builds a qemux86 core-image-minimal image
and kernel in 2.6 MB (compressed):
1.2M bzImage-qemux86.bin
1.4M core-image-minimal-qemux86.cpio.gz
After mounting the rootfs:
$ sudo du -hs .
3.4M .
$ sudo ~/bin/dirsize.py 25000

This image can be tested in qemu with:
qemu-system-i386 -kernel /build/poky/qemux86/tmp/deploy/images/bzImage-qemux86.bin -append "console=ttyS0,115200 root=0800" -nographic /build/poky/qemux86/tmp/deploy/images/core-image-minimal-qemux86.ext2
This results in booting to a busybox shell:
/bin/sh: can't access tty; job control turned off
/ #
This series includes two patches from others that are still pending inclusion,
but are necessary to build poky-tiny images:
o native.bbclass: Fix variable remapping coverage
o license: Fix manifest conditional
The linux-yocto-tiny recipe is a placeholder until the linux-yocto_3.2 recipes
are ready for master. At that time, linux-yocto-tiny will drop all config
fragments in favor of the to-be-in-tree versions and make use of a new
yocto/standard/tiny/base branch. For now, this recipe allows us to build
poky-tiny with a reasonably small kernel.
Several of these patches are known to be suboptimal, but are included to allow
for building and testing the series as well as to illicit feedback. Many of
these "hacks" could be avoided by defining MACHINE-tiny variants and creating a
core-image-tiny recipe and a task-core-tiny task. I'd prefer to avoid all of
those things if possible by making the existing infrastructure flexible enough
to be used with poky-tiny.
Finally, I appreciate that this series is a mix of patches destined for oe-core
and poky. I felt it would be preferable to keep it all together for the RFC, and
to CC those that I knew would be interested. The final request will be sent
piecemeal through the appropriate channels.
Thanks,
Darren

From: Richard Purdie <richard.purdie@linuxfoundation.org>
When looking for RDEPENDS to process, bitbake iterates through PACKAGES
*and* PN. Since native.bbclass sets PACKAGES to be empty, its pointless
remapping the list of PACKAGES since this does nothing. There is a problem
since *_${PN} are used by bitbake but not remapped by the native.bbclass
class extension code.
This changes the code to remap _${PN} in both expanded and unexpanded
forms. We use the unexpanded form since d.expandkeys() has not been called
at the point this code executes. Remapping the expanded form is belt and braces
to cover any case where the unexpanded key form may not be present.
As a result of this, various surprising dependencies are uncovered
and the patch rectifies those. These are real bugs since they're injecting
unneeded (unremapped) dependencies into the dependency chain. Workarounds
for this kind of problem in autoconf are removed.

eglibc-utils RDEPENDS on bash which requires gettext which requires
wchar support. If wchar support is not included in DISTRO_FEATURES,
gettext will fail to compile.
By removing eglibc-utils from the PACKAGES listing, bitbake doesn't
try to build the dependency chain.

keymaps pulls in gettext, which can't build without wide character support.
Rather than have to add a -tiny variant of every MACHINE to drop "keyboard" from
the MACHINE_FEATURES, just enable the DISTRO to define what gets added to
RDEPENDS_task-core-boot when MACHINE_FEATURES includes keyboard via the
VIRTUAL-RUNTIME_keymaps variable. By default, keep "keymaps".

Allow the reuse of poky.conf by distro definitions wanting to remove
content by introducting POKY_DEFAULT_EXTRA_R*. These are appended
to the corresponding DISTRO_EXTRA_R* variables and can be overriden
by distro configs that "require poky.conf".

Poky-tiny is intended for building very small OS images. The distro
definition sets the providers for the kernel and the runtime services.
It also reduces the eglibc component list and other DISTRO_FEATURE
elements.

+# Poky-tiny is intended to define a tiny Linux system comprised of a
+# Linux kernel tailored to support each specific MACHINE and busybox.
+# Poky-tiny sets some basic policy to ensure a usable system while still
+# keeping the rootfs and kernel image as small as possible.
+#
+# The policies defined are intended to meet the following goals:
+# o Serial consoles only (no framebuffer or VGA console)
+# o Basic support for IPV4 networking
+# o Single user ash shell
+# o Static images (no support for adding packages or libraries later)
+# o Read-only or RAMFS root filesystem
+# o Combined Linux kernel + rootfs in under 4MB
+# o Allow the user to select between eglibc or uclibc with the TCLIBC variable
+#
+# This is currently a partial definition, the following tasks remain:
+# [ ] Integrate linux-yocto-tiny ktype into linux-yocto
+# [ ] Define linux-yocto-tiny configs for all supported BSPs
+# [ ] Drop ldconfig from the installation
+# [ ] Modify the runqemu scripts to work with ext2 parameter:
+# runqemu qemux86 qemuparams="-nographic" bootparams="console=ttyS0,115200 root=0800"

NOTE: I'm looking for a more appropriate mechanism.
In order for the kernel to accept an initramfs as a rootfs,
it must have /init - even if it is an empty file. Touch /init
to ensure it exists for cpio and cpio.gz image types.
When used with initrd and rootfs=/dev/ram0, this allows the
cpio and cpio.gz images to be used as the rootfs.

Doh, -ENOQUOTING. Fixed in the dvhart/tiny-v2 contrib branch.

Taking the closer look that I promised. Did you build with printk
completely disabled ? It used to produce invalid images, so I was
curious to know if that has been fixed.
Anytime I see debug, I always think 'optional' (i.e. like the cfg/debug.cfg
that I've had in the past).
98k isn't much to add, but in a crunch, these could easily be made
optional.

As long as we don't end up breaking things down too much, this
is fine. But if there are too many, classifying a set of filesystem
options into named/useful configs works as well. i.e. "settopbox-fs"

I can test this against the allnoconfig staging work, but so I'm clear,
you went for the approach of a defconfig baseline (generated from
allnoconfig?) and then re-enabling what you need/want ?

I don't see anything missing in there, but I see some options as
enabled that surprised me (preempt none, ftrace (but these look
largley like HAVE_* options) or "hardware" options that we can
move to boards at some point. If the approach is what I mentioned
above, then this all looks sane.

All looks sane. At some point, there could be more arch specific
items found here.

Is this bit needed? If so, I'm not seeing a description of this change
in the commit message, unless I'm missing something.

I have indeed, it works fine. I find that leaving it in is the better
option and just setting the LOGLEVEL in the kernel parameters if you
want a silent boot. You get all the boot time advantages while still
being able to debug your kernel.
EARLY_PRINTK and PRINTK_TIME might be something we make options.

Yeah, CONFIG_PRINTK should move into "core policy" I think when we
define the tiny ktype.

I don't even use this one in the recipe, expecting RO fs or initramfs
usage. I left it to easily allow people to add it. The journal takes up
1MB, which is more than 25 of the rootfs :-)

Right, there is nothing interesting in the defconfig, it's just there to
force a bunch of settings that the allnoconfig support will do once it's
in place.

Correct.

It appears to me that Richard just moved these from autoconf_2.68.bb to
autoconf.inc unchanged. The [R]DEPENDS stuff in the recipe may have been
added to work around the issue this patch addresses, and the DEPENDS was
redundant. After removing that and the RDEPENDS* (which are now handled
properly by native.bbclass) moving the remaining 2 DEPENDS_virtuclass*
assignments into the .inc along with the only remaining DEPENDS makes
sense to me.

* [PATCH 9/9] image_types: Ensure /init exists for cpio rootfs archives

NOTE: I'm looking for a more appropriate mechanism.
In order for the kernel to accept an initramfs as a rootfs,
it must have /init - even if it is an empty file. Touch /init
to ensure it exists for cpio and cpio.gz image types.
When used with initrd and rootfs=/dev/ram0, this allows the
cpio and cpio.gz images to be used as the rootfs.
