kbuild: fixing the select problem

kbuild: fixing the select problem

[James Bottomley]

[Sam: I know you don't maintain kbuild anymore, but since you have the
most experience, if you could find time to comment, I'd be grateful]

The select problem is that the kbuild select directive will turn a
symbol on without reference to its dependencies.  This, in turn, means
that either selected symbols must select their dependencies, or that
people using select have to be aware of the selected symbol's dependency
and build those dependencies into their symbol (leading to duplication
and the possibility of getting the dependencies out of sync).  We use
select for the scsi transport classes, so we run into this problem in
SCSI quite a lot.

I think the correct fix is to make a symbol that selects another symbol
automatically inherit all of the selected symbol's dependencies.

There seems to be a fairly easy way to do this in kbuild.  Right at the
moment, select is handled as additional symbol values as the last point
in the symbol tree evaluation process.  Instead, what I propose doing is
for every select symbol, we add an extra unconditional default for the
selected symbol of the selecting symbol's current value (this breaks a
possible dependency cycle) and add to the dependencies of the selecting
symbol, the symbol it's currently selecting.

There's one wrinkle to all of this in that the current parser for
default values stops when it finds the first valid (i.e. whose if clause
evaluates to true) default.  To make the above scheme work, I need to
modify the default parser so it takes the highest tristate of all the
valid defaults (and bumps m to y for bool).

Does this look acceptable to people?  I think it should give the desired
result and has the added benefit that we can then strip the extra select
overlay out of the kbuild system (making the parser slightly simpler).

If this looks like a good idea to people, I think I can code up a quick
patch.

What if there's a good reason the selected symbol has this dependency?
E.g. it depends on a critical feature not available? Like CONFIG_HAS_IOMEM?

I don't quite understand the question.  If a selected symbol has a
critical dependency which is config'd to N then the build usually
breaks ... that's what I'm calling the select problem.  I thought
CONFIG_HAS_IOMEM was usually selected by the architecture, though.  In
the new proposal, we wouldn't be able to generate the invalid
configuration in the first place.

Sorry, my fault, -EREPLY_TOO_EARLY_AFTER_WAKEUP.
Upon rereading what you actually wrote, it made complete sense, and my
question didn't.

I think Geert is asking "If the arch says CONFIG_HAS_IOMEM=n, but some driver
does a 'select CONFIG_FOO' which then (under your proposal) forces the
value CONFIG_BAR=y, which eventually ends up with CONFIG_HAS_IOMEM=y, what
should the behavior be?"

(I suspect the right answer here is "one of the symbols is buggy and its
'select' should be a 'depends' instead", but somebody else better double-check
that conclusion - I'm hardly a Kconfig expert).

We should check if some Kconfig file doesn't rely on this "first hit"
behavior and fix it to explicitly list the condition for a given
default. Another option would be to add
default SYM1 || SYM2
to a symbol selected by SYM1 and SYM2.

Other than the above, right now I don't see any issues with such approach.

On a related note, I see Vegard's GSoC project to use a sat solver for
kconfig got accepted [1]. Vegard, how is the project progressing?

I actually asked kconfig to generate the list of symbols (in my config)
with multiple defaults.  It's pretty small and the default y seems to be
the thing with multiple if clauses, so they act like or statements.

The list is

USB_ARCH_HAS_HCD has 4 defaults
DEFCONFIG_LIST has 5 defaults
MAC80211_RC_DEFAULT has 2 defaults
X86_L1_CACHE_SHIFT has 2 defaults
SPLIT_PTLOCK_CPUS has 2 defaults
X86_MINIMUM_CPU_FAMILY has 3 defaults
DEFAULT_TCP_CONG has 2 defaults
DEFCONFIG_LIST has 5 defaults

X86_L1_CACHE_SHIFT has 2 defaults
X86_MINIMUM_CPU_FAMILY has 3 defaults
SPLIT_PTLOCK_CPUS has 2 defaults

Here's a patch that alters the default processing to the needed form and
checks the old vs new values.  I've been running randconfigs but I can't
get the warning to trip ... have at it.

I don't see the warning, but I took a problem config from linux-next 2010-0506
(today) [attached].  In it, CONFIG_TCG_BIOS_LOG=y and that selects ACPI,
so now ACPI is enabled, but ACPI depends on PM and PCI, but they are still not
selected...

or is this only step 1 of a multi-step implementation?

Actually, it's not any step.  It's just validation of the contention
that I can alter the default parser from taking the first valid default
to calculating the or of the defaults without changing the current
kbuild behaviour.

The patch to fix kbuild goes on top of this change minus the warnings
(when I actually code it up).

Hi,

Yes, that is true :-) I was planning to send an announcement to LKML
this weekend. Actual coding doesn't start until the last week of May.

So hopefully we can soon get rid of select altogether :-)

You may want to have a look at a patch I proposed some time ago, which
at just warns of selecting options with unmet dependencies. I think it's
a better approach that forcing the selection of the dependencies:
