[PATCH] Kconfig update

[Jesse Barnes]

Just a small patch to fix the ACPI_NUMA default for ia64 and sn2.

Btw, I'm not on the list, so if you reply please Cc: me.

Thanks,
Jesse

[PATCH] kconfig update

[Roman Zippel]

Hi,

At http://www.xs4all.nl/~zippel/lc/patches/ there is a series of patches 
for 2.5.70 as I want to sent them soon to Linus (kconfig-2.5.70.diff.gz 
contains all the other patches). I only want to update the documentation a 
bit before this.
Changes to the last patch besides smaller fixes:
- choices should be more readable now during 'make config'
- saving configuration into a different directory fixed

bye, Roman

[PATCH] kconfig update

[Roman Zippel]

Hi,

It took a bit longer than I wanted, but here is finally another kconfig 
update. There are two important changes: I included Romain's gtk front 
end and the support for the menuconfig keyword. Unfortunately the first is 
lacking a bit support for the latter. Romain, you have to check that menu 
entries of type P_MENU can now also have a config symbol. I looked a bit 
at it myself but my gtk knowledge is insufficient. :)
Other changes are small parser fixes and the config list in qconf has a 
parent entry, so it should be more obvious, how to get to a parent menu.
I don't expect bigger problems, so I want to send this patch soon to 
Linus.
The patch is at http://www.xs4all.nl/~zippel/lc/patches/kconfig-2.5.64.diff

bye, Roman

Any chance you could take a look at the patch that links lxdialog directly
to menuconfig instead of requiring the separate binary?  It has been
around for a long time and seems like a very worthwhile change, imho.

It is me responsible for the delays and not being integrated yet, unfortunately
I didn't have time for proper debugging one problem in it yet :-( (broken
window resizing handler; Roman proposed some solution which I didn't manage to
try yet). I hope I will finally give it a final kick really soon.

BTW here is a simple menuconfig example, if someone wants to know, how it

Hi Roman.
Is it on your TODO list to make is more quiet?
Today kconfig dumps out a lot of info when run, making sure no-one even
notices the warnings that occur in the beginning.
When executing
$ make defconfig
$ make V=0
kconfig count for almost half of the output.

It would be really good if the following targets were quiet:
oldconfig, defconfig, all*config.
oldconfig obviously needs to display some info when asking users
for new options.

Also try executing conf with no arguments...

What do you mean? 2.5.64 has no V option.

It is only present in linus-BK-latest - sorry.
"make V=0" is a shorthand for "make KBUILD_VERBOSE=0".
In other words a way to disable the 'noise' generated
when building the kernel.

I still don't see what you mean. :)
Which noise exactly do you want to disable? With "make KBUILD_VERBOSE=0" I 
only see normal build messages.

Sample output:
$ make mrproper
$ make KBUILD_VERBOSE=0 defconfig
  HOSTCC  scripts/fixdep
  HOSTCC  scripts/split-include
.....
  HOSTLD  scripts/kconfig/conf
SAM> Until here, just normal build output

$ _

So executing "make KBUILD_VERBOSE=0 defconfig"
results in ~930 lines of output, including one warning message.

What I request is that conf outputs essential stuff only, for example
warnings.
That would remove 900 lines of output when building a kernel,
and maybe people actually paid attention to the warnings generated
by kconfig.

In general I prefer minimum output when building the kernel, without
loosing the ability to follow progress.
One reason why we have some of the warnings left all around in the kernel is
due to the fact people does not see them when building their drivers etc.
With default options to make, warnings simply does not show up as visible,
and when the build proceeds the relevant parts scroll out.

See my point now?

Also speaking about warnings. How about sticking in a "warning:",
to make the format gcc compatible.
Something like attacted patch.

defconfig is special case (like all{yes,no,mod}config). They basically 
set all options to a new value and print out the new config.
oldconfig could be less verbose and actually there is already a less 
verbose mode. If you skip the oldconfig step, the config tool is called 
anyway and checks the configuration and only asks as necessary. The same 
mode could be used for oldconfig, but I didn't want to change the 
behaviour needlessly. OTOH for oldconfig it should be no problem to call 
conf with '-s' instead of '-o' for the KBUILD_VERBOSE=0 case.

Um, my gcc doesn't produce any "error:" prefix.

The reason to respond is that all the output from conf looks useless.
What is the usage of conf being so verbose?
If it is required then keep it. But making conf that verbose only
because configure was that verbose . There is no point in that.

Not a needlessly change, but more in the area - it was about time..
