This patch set provides enough to demo how the Kconfig fragment based defconfigs could be used to simplify both generating and managing the configs used to build Linaro kernels.
This is for the kernel config managment tool and dependent bluprints: https://blueprints.launchpad.net/linux-linaro/+spec/other-kernel-config-mana...
The basic idea is to use a Kconfig fragment to generate the per-board defconfigs. The Kconfig fragments contain a meta-option that defaults to yes, which then selects the needed config values to enable a system.
This has been proposed by others, and we're using Stephen Rothwell's initial patch to start things off.
Once we have the infrasturcture to use Kconfig fragments for defconfigs we had to overcome some limitations: 1) We cannot select items from a choice block 2) We need a way to select for values and modules.
Limitation #1 is resolved by a patch to the kbuild system I made.
Limitation #2 is unsolved, but Jason Hui found a workaround that is sufficient. Basically we can just redefine the default with a short declaration: config VAL default 256 or config VAL default m
With these two solutions, I went forward generating basic Kconfig fragments for omap3, imx51 and vexpress.
Getting per-board defconfigs is only of limited value, because we also want to be able to have a common policy settings for Linaro kernels. Many distros run into this problem, and use .config fragments which are then assembled at package build time.
My solution is to have a Kconfig.distro file, which is patched with Distro specific policy config, such as which filesystems should be enabled, networking policy, debug options, or periphrial driver modules that should be enabled. Basically anything that isn't hardware specific (by that I mean, part of the architecture or wired on the board).
From there, I add in as much of the generic Linaro config policy
as I could, utilizing the config files that were used to build the omap3, imx51 and vexpress hardware packs.
Since the Linaro config polciy is not unified at this point (in other words, each board has totally different set of generic policy options configured). I added the per target differences into the board kconfig fragments.
Ideally we can review and settle down on specific linaro config policy and this generic per-board stuff can go away.
These are initial and rough patches, but are the result of lots of painful manual labor to match the Linaro .configs as closely as possible.
There are a few remaining issues, but these can probably be worked around: 1) Omap has a strange tristate choice option for the usb gadget options. So you can only pick one, or you can pick multiple items as modules. My choice selection patch doesn't yet address this. I need to see how common this style of choice is and see if we can either just make it a non-choice options block or if other fixes are needed.
2) Not having a module selction is a little painful, as the module "default m" entries are numerous and annoyingly separate from the meta-config selects.
3) The Kconfig.distro file should be probably broken up into policy topics, like networking, filesystems, peripherials, etc.
4) The current board Kconfig fragments are named slightly differently from the standard defconfigs to allow testing with both. That will need to be fixed, and the old defconfigs removed prior to submitting.
5) The igep, overo, and panda configs all use the same omap3 config according to the hwpacks. I'm not sure I believe that, but went along with it to get this out the door.
Many thanks to Jason for his help figuring out an approach here.
Feedback and thoughts would be greatly appreciated.

In looking at trying to replace defconfigs with kconfig fragments, one limitation identified is that config items in choice blocks cannot be selected by other config options.
One way to doge this would be to create non-visible meta options that change the choice block's default, but that would require additional meta-configs per-choice config, plus a conditional default per meta-config. That just seemed too ugly.
So I looked into how to allow the choice default to be overrided by a select statment, and the following patch is the result.
I'm very new to kconfig code, so I expect that my changes are probably broken in some subtle way, but in my testing it seems to work. The select only chagnes the default, which can be overrided by the user via the menu. This allows kconfig fragments to work for make defconfig, while not restricting user customization.
Thoughts and feedback (or alternate approaches) would be appreciated.

The patch looks fine to me (as far as my little Kconfig knowledge goes). Two comments about the submission form though:
* Ideally, the initial description is split into two parts: one that is suitable as a changelog and the other that is your personal comment, including the "thanks" part, and put it below the --- line, so that git can automatically cut it.

And linux-kernel. This definitely needs wider circulation, and I'd like to see a push to get this accepted upstream before adding it to the Linaro kernel tree.

Yea, although early on I tend to be a little more informal, I do usually clean up the commit log before actually submitting anything more then RFC level code.
- I think you should also Cc the Kconfig maintainer, Roman
Zippel zippel@linux-m68k.org, and linux-kbuild@vger.kernel.org.
This patch was actually submitted to both a few weeks ago. In this case, as I'm trying to RFC the overview of what I'm trying to accomplish specifically on the linaro list, I trimmed the cc list. Once I sort out the Linaro distro policy bits, and can drop the last quarter of the patch set, I'll likely resubmit the entirety to the kbuild list (and Roman, although he seems to be MIA these days).
thanks for the feedback! -john

After this change, doing a "make xxx_defconfig" will check first for a file called arch/<arch>/configs/Kconfig.xxx and use that to generate the .config (effectively starting from an allnoconfig). If that file doesn't exist, it will use arch/<ARCH>/configs/xxx_defconfig as now.

Sort of a hack.
With the new kconfig framents, some config items may be defined in a different order then usual. To preserve the normal order, re-run sildentoldconfig after running defconfig.

I think we want something more flexible than sourcing a global Kconfig.distro from the board file.
First of all, we want at least three levels, as Amit mentioned: distro, arch, board. I can think of at least another one: "flavor" for common variants of the distro config, e.g. if you want to enable a lot of debugging options or turn your root file systems into =y so you can work without initramfs.
Would it be possible to pass multiple Kconfig fragments to the Kconfig parser instead of just one top-level file that sources all the other ones?

Yep. I'd like to do exactly this in the future (probably a first pass will just generate a tmp file that sources the multiple fragments provided).
But I wanted to get the proof of concept out there first, so it hasn't been as much of a priority.

They currently use the same binary kernel, so it's actually correct :-) They are in different hwpacks because they have different u-boot.bin/MLO and boot args.

This is for the kernel config managment tool and dependent bluprints: https://blueprints.launchpad.net/linux-linaro/+spec/other-kernel-config-mana...
The basic idea is to use a Kconfig fragment to generate the per-board defconfigs. The Kconfig fragments contain a meta-option that defaults to yes, which then selects the needed config values to enable a system.
This has been proposed by others, and we're using Stephen Rothwell's initial patch to start things off.
Once we have the infrasturcture to use Kconfig fragments for defconfigs we had to overcome some limitations:
- We cannot select items from a choice block
- We need a way to select for values and modules.
Limitation #1 is resolved by a patch to the kbuild system I made.
Limitation #2 is unsolved, but Jason Hui found a workaround that is sufficient. Basically we can just redefine the default with a short declaration: config VAL default 256 or config VAL default m
With these two solutions, I went forward generating basic Kconfig fragments for omap3, imx51 and vexpress.
Getting per-board defconfigs is only of limited value, because we also want to be able to have a common policy settings for Linaro kernels. Many distros run into this problem, and use .config fragments which are then assembled at package build time.
My solution is to have a Kconfig.distro file, which is patched with Distro specific policy config, such as which filesystems should be enabled, networking policy, debug options, or periphrial driver modules that should be enabled. Basically anything that isn't hardware specific (by that I mean, part of the architecture or wired on the board).
The Ubuntu configs do something similar. The config generator makes a 3-level config - distro, arch, board.
But this is encapsulated under the debian packaging rather than in the kernel source. That is why you probably haven't seen it yet. Look at git://git.linaro.org/ubuntu/linux-linaro-natty.git under debian.linaro/config.
Most kernel developers, however, don't really care about creating a .deb package of the kernel to test new code. They'd rather have the config available in the sources. So I agree that we should fix this problem for them. If it turns out that in fixing this problem we fix it for distros too, great!
From there, I add in as much of the generic Linaro config policy as I could, utilizing the config files that were used to build the omap3, imx51 and vexpress hardware packs.
Since the Linaro config polciy is not unified at this point (in other words, each board has totally different set of generic policy options configured). I added the per target differences into the board kconfig fragments.
No, it doesn't. The system they use allows for unified configs. The Ubuntu kernel has unified configs across 3-4 architectures.
The problem is starting a new config for a new board/SoC. The current config system expects a full config for the board dropped into place and then let the tool split it out into distro/arch and board components. If this causes any changes to the distro/arch configs, you know you might have missed some options.
Ideally we can review and settle down on specific linaro config policy and this generic per-board stuff can go away.
These are initial and rough patches, but are the result of lots of painful manual labor to match the Linaro .configs as closely as possible.
There are a few remaining issues, but these can probably be worked around:
- Omap has a strange tristate choice option for the usb gadget
options. So you can only pick one, or you can pick multiple items as modules. My choice selection patch doesn't yet address this. I need to see how common this style of choice is and see if we can either just make it a non-choice options block or if other fixes are needed.
- Not having a module selction is a little painful, as the
module "default m" entries are numerous and annoyingly separate from the meta-config selects.
- The Kconfig.distro file should be probably broken up into
policy topics, like networking, filesystems, peripherials, etc.
- The current board Kconfig fragments are named slightly
differently from the standard defconfigs to allow testing with both. That will need to be fixed, and the old defconfigs removed prior to submitting.
- The igep, overo, and panda configs all use the same omap3
config according to the hwpacks. I'm not sure I believe that, but went along with it to get this out the door.
They do use the same config - or 'flavour' as they are referred to in the Ubuntu kernel config system.
Many thanks to Jason for his help figuring out an approach here.
Feedback and thoughts would be greatly appreciated.

Panda is OMAP4 and the other two are OMAP3 AIUI, I am aware they are all under "OMAP2+" in the kernel, but there are really significant differences from configuration point of view like SMP or not.
How is that handled with the same config?

One can build a single kernel binary that runs on OMAP2/3/4 platforms from the mainline kernel. That has been the main requirement from the maintainer to add new board support. Everything under mach-omap2 and plat-omap is written for runtime detection of features.
However, last I looked, there were problems with the ARM locking primitives being patched at runtime. So it prevented SMP-on-UP kernels, that is, SMP had to be turned off. But that will eventually get fixed so you could have a SMP kernel running on a UP system. This is how x86 does it today.

I take it this magic of SMP or not is hidden in this config layering scheme you mentioned and it isn't really using the same config for say igep0020 and Panda. In any event, there's a performance tradeoff running SMP kernel on uniprocessor to consider too.
Absolutely that's the future... in fact the bootloader should work the same way with one per-arch bootloader that detects what it is running on at runtime, and at that point device-specific point hwpacks become very thin or non-existent and there's an epic reduction in how many different binaries are needed to support many boards.

No, it is in the black depths of ARM assembly and TBH, it is voodoo to me. Nothing to do with kernel config as such. The SMP kernel, at runtime, (binary) patches itself to convert locking primitives to no-ops in the UP case. Or something to the effect.
Panda. In any event, there's a performance tradeoff running SMP kernel on uniprocessor to consider too.
Apparently, with this one-time patching (per boot) there isn't such a tradeoff.

Hum my IGEP0020 config here has CONFIG_BROKEN_ON_SMP=y set so I guess this is to do with what you mentioned.

SMP-on-UP appears to be fully working nowadays. We currently don't build a single SMP kernel for omap4 and omap3, but I've been playing with that and it's been shown to work. Does anyone know whether we're planning to move to a single OMAP kernel? Has anyone measured the performance delta?
In principle, we could make this move; but there could be issues I'm not aware of.
Note that the SMP-on-UP support is fairly minimal -- only those things which literally will fail on UP are patched out.

Panda. In any event, there's a performance tradeoff running SMP kernel on uniprocessor to consider too.
Apparently, with this one-time patching (per boot) there isn't such a tradeoff.
OK thanks for the explanation.
SMP-on-UP appears to be fully working nowadays. We currently don't build a single SMP kernel for omap4 and omap3, but I've been playing with that and it's been shown to work. Does anyone know whether we're planning to move to a single OMAP kernel? Has anyone measured the performance delta?
In principle, we could make this move; but there could be issues I'm not aware of.
Note that the SMP-on-UP support is fairly minimal -- only those things which literally will fail on UP are patched out.
Do you have a pointer to the patches that enabled this support? SHA ids are fine. I'm curious what the runtime patching voodoo looks like.

linux-linaro-omap runs on omap[34] and has for most of this cycle. Currently CONFIG_SMP and CONFIG_SMP_ON_UP are both on.
OMAP4 has had some glitches, first no display then broken display. The next release has display with blue text just like the Ubuntu kernel:). Since linux-linaro-omap is based on upstream or headed upstream patches it does not have all the functionality of the Ubuntu ti-omap4 kernel.
In principle, we could make this move; but there could be issues I'm not aware of.
Note that the SMP-on-UP support is fairly minimal -- only those things which literally will fail on UP are patched out.

Absolutely that's the future... in fact the bootloader should work the same way with one per-arch bootloader that detects what it is running on at runtime, and at that point device-specific point hwpacks become very thin or non-existent and there's an epic reduction in how many different binaries are needed to support many boards.
I can hear the collective sighs of appreciation from distribution maintainers :)

No, it doesn't. The system they use allows for unified configs. The Ubuntu kernel has unified configs across 3-4 architectures.
Ofcourse, I meant "No, it is (unified). It is just a bit hard to get right currently."

The Ubuntu configs do something similar. The config generator makes a 3-level config - distro, arch, board.
But this is encapsulated under the debian packaging rather than in the kernel source. That is why you probably haven't seen it yet. Look at git://git.linaro.org/ubuntu/linux-linaro-natty.git under debian.linaro/config.
Most kernel developers, however, don't really care about creating a .deb package of the kernel to test new code. They'd rather have the config available in the sources. So I agree that we should fix this problem for them. If it turns out that in fixing this problem we fix it for distros too, great!
Yea, I am aware of some of the approaches that distros use, usually assembling .config fragments into a larger config at build time.
And its in part because each distro has tried to solve the same issue out of the kernel that I'm interested in trying to solve the problem in the kernel source at the Kconfig level.
From there, I add in as much of the generic Linaro config policy as I could, utilizing the config files that were used to build the omap3, imx51 and vexpress hardware packs.

Huh. Are you sure? Because the configs found in the hwpacks are very different. I'll grant that the build system allows for unified config, but I don't think the Linaro kernels are making much use of it.
omap vs vexpress being the best example of really wide differences: o cgroup support o bsd process accounting o xattr support for ext3/ext4 o different preempt models o highres timers & no_hz etc..
The problem is starting a new config for a new board/SoC. The current config system expects a full config for the board dropped into place and then let the tool split it out into distro/arch and board components. If this causes any changes to the distro/arch configs, you know you might have missed some options.
I'll have to take a look at this.

Yes, the configs in the packaged kernel are not in sync. The reason is mostly historical. The omap config started with a ubuntu kernel config which is indeed unified across arches so it has lots of stuff on that we probably don't need in a linaro kernel.
The other configs started as configs from the kernel def configs plus whatever it took to make the config checker happy (things like security issues). We probably would not break may linaro supported platforms if we stripped down the omap config to be more similar to the other SOCs. I thought at one time that this was not a good idea because there was a plan for ubuntu to use the linaro omap kernel. That has not yet happened so at this time having the linaro omap kernel config out of sync with the ubuntu one may not be a problem.
The problem is starting a new config for a new board/SoC. The current config system expects a full config for the board dropped into place and then let the tool split it out into distro/arch and board components.
