NACK.  This changes other configuration options in addition, for example
in collie_defconfig:

-CONFIG_MTD_OBSOLETE_CHIPS=y
-# CONFIG_MTD_AMDSTD is not set
-CONFIG_MTD_SHARP=y
-# CONFIG_MTD_JEDEC is not set

That's not a problem introduced by my patch.

Either the depency of MTD_OBSOLETE_CHIPS on BROKEN is correct (in which 
case CONFIG_MTD_OBSOLETE_CHIPS=y wouldn't bring you anything), or the 
dependency on BROKEN is not correct and should be corrected.

David, can you comment on this issue?

It's a problem introduced by your patch because the resulting defconfig
file becomes _wrong_ by your change, and other changes in the defconfig
are thereby hidden.

If you change any options in a defconfig file, and they're obviously not
leaf options, you should check what impact they have on other options by
running it through an "oldconfig" cycle.  That's what I just did with
this script:

#!/bin/sh -e
alias amake='make CROSS_COMPILE=arm-linux- ARCH=arm'
amake $1 O=../build/t >/dev/null 2>&1
mv ../build/t/.config ../build/t/.config.orig
sed '/CONFIG_BROKEN/d;s,^# CONFIG_CLEAN_COMPILE is not set,CONFIG_CLEAN_COMPILE=y,' < ../build/t/.config.orig > ../build/t/.config
amake oldconfig O=../build/t >/dev/null 2>&1
diff -u ../build/t/.config.orig ../build/t/.config

Hence I discovered that disabling CONFIG_BROKEN removes the above
options for the collie case.

BTW, it might be worth using something like the above script for all
the changes to the defconfig files in your patch so that it correctly
updates these files.  It will also mean that any review of it is more
meaningful because we can see the full extent of your changes.

That's something which collie folk need to comment on.  However, what
I can say is that the collie_defconfig builds successfully today:

http://armlinux.simtec.co.uk/kautobuild/2.6.15-rc5-git1/collie_defconfig/zimage.log

so it's quite possible that the Kconfig is out of sync with reality.

It's a problem introduced by your patch because the resulting defconfig
file becomes _wrong_ by your change, and other changes in the defconfig
are thereby hidden.

If you change any options in a defconfig file, and they're obviously not
leaf options, you should check what impact they have on other options by
running it through an "oldconfig" cycle.  That's what I just did with
this script:

#!/bin/sh -e
alias amake='make CROSS_COMPILE=arm-linux- ARCH=arm'
amake $1 O=../build/t >/dev/null 2>&1
mv ../build/t/.config ../build/t/.config.orig
sed '/CONFIG_BROKEN/d;s,^# CONFIG_CLEAN_COMPILE is not set,CONFIG_CLEAN_COMPILE=y,' < ../build/t/.config.orig > ../build/t/.config
amake oldconfig O=../build/t >/dev/null 2>&1
diff -u ../build/t/.config.orig ../build/t/.config

Hence I discovered that disabling CONFIG_BROKEN removes the above
options for the collie case.

BTW, it might be worth using something like the above script for all
the changes to the defconfig files in your patch so that it correctly
updates these files.  It will also mean that any review of it is more
meaningful because we can see the full extent of your changes.

That's something which collie folk need to comment on.  However, what
I can say is that the collie_defconfig builds successfully today:

http://armlinux.simtec.co.uk/kautobuild/2.6.15-rc5-git1/collie_defconfig/zimage.log

so it's quite possible that the Kconfig is out of sync with reality.

No, CONFIG_BROKEN=y in a defconfig file is a bug.

Either the defconfig doesn't use BROKEN code in which case it's simply 
wrong, or it's a wrong workaround (as in the CONFIG_MTD_SHARP case) for 
a wrong BROKEN dependency.


And it's a dangerous workaround:

Consider e.g. that "both marked as obsolete and BROKEN" are the best 
candidates for "remove obsolete code" cleanups - and there goes your 
driver to /dev/null ...

Indeed, but that's not the point. A defconfig file should be the result 
of running one of the various configuration targets; yours are 
hand-patched. If you run the defconfig target, it will copy the config 
file and run oldconfig, thus resulting in a different configuration file 
(because options may now be gone and hence disabled) than what was in 
the defconfig, and thus people may come to the wrong conclusion that if 
a driver is enabled in a defconfig file, it will be built.

defconfig files are virtually never a configuration for the kernel they 
are shipped with since they aren't updated every time some configuration 
option is changed.

Consider a defconfig with CONFIG_BROKEN=n, and a driver that is enabled 
in this defconfig gets for some reason marked as broken in the Kconfig 
file - this will give exactly the same result as the one you describe.

Adrian,

The defconfig files in arch/arm/configs are for platform configurations
and are provided by the platform maintainers as a _working_ configuration
for their platform.  They're not "defconfigs".  They got called
"defconfigs" as a result of the kbuild "cleanups".  Please don't confuse
them as such.

If, in order to have a working platform configuration, they deem that
CONFIG_BROKEN must be enabled, then that's the way it is.

Therefore, I request that either you leave the ARM platform configurations
well alone, or follow the advice I've given so that we can _properly_
assess the impact of your changes.

Thanks.

They might be broken in other situations.  However, if you look at
the latest build at:

 http://armlinux.simtec.co.uk/kautobuild/

you'll notice that all, even the ones with CONFIG_BROKEN build
successfully.  Without any bug reports to the contary, we must
assume that the configuration files supplied by the folk who
developed the support for the platform are correct and working.

Therefore, CONFIG_BROKEN may have been added to configuration
options which don't work for some particular small corner cases.

This brings on to another subject.  If we mark something broken
we should say _why_ we're doing so, especially if it is non-obvious.
That seems to be the case here - if these drivers are broken, it's
non-obvious why they're broken.

So, all in all, CONFIG_BROKEN is a broken idea in itself!

The bug in this case was the (implicit) BROKEN dependency of MTD_SHARP.

Such corner cases could easily be handled using
	depends on (BROKEN || SA1100_COLLIE)

Or in other cases wie have
	depends on (BROKEN || !64BIT)

If it works its not BROKEN, and we can express this.

The vast majority of drivers depending on BROKEN simply don't compile.

How many examples besides MTD_SHARP can you name where you have problems 
to determine why something is marked as BROKEN?

> So, all in all, CONFIG_BROKEN is a broken idea in itself!

The idea behind BROKEN is to not offer drivers where we know that they 
don't compile or will for sure not work to users.

The ARM case that people are using the supplied defconfig's more or less 
unchanged is a big exception.

if a working platform configuration configuration requires 
CONFIG_BROKEN=y, the problem is a bug that should be fixed properly.

We are talking about a class of bugs that can usually be easily fixed if 
reported - so why aren't they reported?

The MTD_SHARP case is a good example, because otherwise I might have 
soon sent a patch that would have removed this driver with the rationale
"both marked as obsolete and BROKEN can clearly be removed".

Unless someone can tell me a valid case for enabling BROKEN that does 
both create a working configuration and not hide real issues it seems 
the approch below might be the way to go.

Yes, you might dislike this at the first sight.

But if you consider that although this might result in a short-term 
breakage of some configurations, this will also result in proper bug 
reports and fixing of the wrong BROKEN dependency bugs, I hope you agree 
that this will actually improve the situation.

Let's assume users don't have any hardware (e.g. several SATA drivers)

If a kernel developer really wants to enable BROKEN drivers, my patch 
still gives them the possibility to do so with a trivial edit of
init/Kconfig.

I agree, and it's very convenient to be able to enable it in

Maybe they're only broken for a small subset of platforms, and someone
added a BROKEN without properly considering whether it should be global
or not?

I don't disagree with the overall notion that CONFIG_BROKEN should not
be set _where_ _possible_.  However, if it needs to be set to get the
required options, then that's what needs to happen until such time that
the above is corrected.

However - and now to the main bug bear - how can we tell what is really
broken if you _just_ change the default configuration file settings for
CONFIG_BROKEN?  What happens is that, on review, we see a simple change.
We'd assume that it has little impact, and we accept that change.

Maybe a month or two down the line, someone whines that their platform
doesn't work for some reason, and it's tracked down to this and the
resulting fallout from disabling CONFIG_BROKEN.

That means that the original review was _worthless_.  It wasn't a
review at all.

So, what I am trying to get across is the need to show the _full_ set
of changes to a default configuratoin when you disable CONFIG_BROKEN,
which is trivially producable if you run the script I've already posted.

You can even use that in conjunction with your present patch to produce
a patch which shows _exactly_ _everything_ which changes as a result of
disabling CONFIG_BROKEN.  Surely giving reviewers the _full_ story is
far better than half a story, and should be something that any change
to the kernel strives for.

If not, what's the point of the original change?

Where is the bug report from the person who set CONFIG_BROKEN=y in the 
collie defconfig that the BROKEN dependency on MTD_SHARP was wrong?

The whining is the bug report the person who set the CONFIG_BROKEN=y in 
the defconfig didn't send.

And things would have been even worse if I had sent a patch erasing 
MTD_SHARP from the kernel because code "both marked as obsolete and 
BROKEN can clearly be removed" and the code was therefore completely 
removed two months before the first person whined?

The point is that I haven't yet heard any good reason for 
CONFIG_BROKEN=y in a defconfig.

No, it's not a good reason if someone used it as a workaround instead of 
sending a bug report that would result in a fixing of the wrong BROKEN 
dependency.

I don't see any justification for MTD_OBSOLETE_CHIPS depending on
BROKEN. That option covers a few of the obsolete chip drivers which
people shouldn't be using any more -- and I'm perfectly willing to
believe that one or two of those don't work any more, but if that's the

As things stand, collie doesn't work with the unmodified mainline
obsolete chips driver but doesn't work with CFI either. Updating the
defconfig isn't really going to help one way or the other as both are
broken in some way.

A patch does exist to make the obsolete chip driver work on collie and
it could probably be made acceptable to mainline but I doubt David would
apply it as he (understandably) wants the "obsolete" driver to die.

I'm just a spectator in this as I don't have access to hardware to work
out what the problem with CFI is. I agree CFI is the way to go but until
it works, every real world configuration is going to use the patched
obsolete driver.

Adrian Bunk:
> The vast majority of drivers depending on BROKEN simply don't compile.

In this case the sharp driver didn't use to compile but does now since
my patch to fix it was applied. If broken means doesn't compile, the
driver does now and the broken status can be removed. It should work on
the platforms it originally worked on. It is still missing some code
that's needed to make it work specifically on collie but I guess that's
a separate issue.

[2.6 patch] don't allow users to set CONFIG_BROKEN=y

[Adrian Bunk]

Do not allow people to create configurations with CONFIG_BROKEN=y.

The sole reason for CONFIG_BROKEN=y would be if you are working on 
fixing a broken driver, but in this case editing the Kconfig file is 
trivial.

Never ever should a user enable CONFIG_BROKEN.

NACK.  MTD_OBSOLETE_CHIPS still hasn't been fixed and must be fixed

I disagree (slightly) with this patch for a few reasons:

- It's very convenient to be able to enable it through menuconfig.

- Being able to easily enable it in menuconfig, then browse through
the menus to look for something matching your hardware is nice, even
if that something is marked BROKEN at least you've then found a place
to start working on. A lot simpler than digging through directories.

- Some things marked BROKEN may not be 100% broken and may actually
work for some specific things, so if you know that it works for your
use, then being able to easily enable BROKEN and then whatever it is
you need is nice.

Perhaps just move it below the Kernel Hacking menu instead, users
don't go there (or if they do they damn well should know what they are
doing).

Ohh well, if it gets removed I won't really cry, but I do think it's
convenient, and if moved into Kernel Hacking it should be mostly out
of harms (read: users) way.

Our menus are mostly made for _users_.

The more common are users accidentially enabling CONFIG_BROKEN and then 
wondering why a driver isn't compiling or working.

And in my experience, when searching whether hardware might be supported 
a grep through the kernel sources brings you more than reading often 
outdated Kconfig help texts. Besides this, a BROKEN driver usually has 
the same value for the user as a non-existing driver.

In reality, people accidentially turn on CONFIG_BROKEN, enable a broken 
driver, and wonder why it isn't working as expected.

If you know the driver is marked as BROKEN and if you want to use it 
despite this, editing the Kconfig file is trivial.

Unless you _really_ know what you are doing, no driver for your hard 
disk is better than a broken driver.

I go with it.

I had CONFIG_BROKEN on, which 'cost' me one post to LKML to find out that
CONFIG_MTD_AMD... does rightfully not compile. It (CONFIG_BROKEN/CLEAN_COMPILE)
just confuses.

at various times over the years I've needed it to enable partially working 
drivers for several things.

true, but do you really want to raise the barrier for users to test 
things? or do you intend to have a bunch of patches that remove BROKEN for 
a config option so that people can test them during the -rc and then add 
it back for them all before a real release?

it depends on how broken something really is, in some cases you are 
correct, in others you aren't.

so have CONFIG_BROKEN taint the kernel if you want to identify it in 
bugreports.

for your hard drive you are probably right, but does this always apply for 
your network card? or your sound card?

this is a reasonable option, although currently nothing in Kernel Hacking 
enables items in other menus. it's convienient that when useing menuconfig 
and working down from the top you first hit the selections that enable 
things in all the other menus (experimental and broken).

If an option is untested it's EXPERIMENTAL.
If it's broken it's BROKEN.

If an option is marked as BROKEN but works fine for you please send a 
bug report.

It's so broken that a devloper said EXPERIMENTAL is not enough, users 
should really not see it. Often the developer additionall added an 
#error to the driver.

It might be marked as BROKEN because it crashes the kernel.

But well, the common case is that the code marked as BROKEN simply 
doesn't compile.

my point is that if someone sends a patch that they think will fix 
something, nobody will be able to test that patch unless they are willing 
to edit their kconfig file unless the patch also marks it unbroken before 
anyone else has tested it.

Kernel developers usually aren't _that_ dumb:
The patch that fixes the driver simply removes the dependency on BROKEN.

It might be nice if you could enable "show BROKEN" options, and have them 
appear in the list without being able to select them...

But then you can accidentally enable something else that really is broken 
in the way you're going to use it. What you really want is to be able to 
override the BROKEN marking on individual options, not to override all 
BROKEN markings. Perhaps there should be a way to enable an option with 
unmet dependencies, such that the dependencies are treated as enabled for 
the purpose of building, but not for the purpose of making options that 
also depend on the same things available. This would also be nice for the 
case where you don't generally want EXPERIMENTAL drivers, but you do want 
a particular one that you've personally found to be stable.

[2.6 patch] don't allow users to set CONFIG_BROKEN=y

[Adrian Bunk]

Do not allow people to create configurations with CONFIG_BROKEN=y.

The sole reason for CONFIG_BROKEN=y would be if you are working on 
fixing a broken driver, but in this case editing the Kconfig file is 
trivial.

Never ever should a user enable CONFIG_BROKEN.
