Petition against kernel configuration options madness...

[Jos Hulzink]

Hi,

It took me about an hour to find out why my keyboard didn't work in 2.5.45. 
Well... after all it seemed that I need to enable 4 ! options inside the 
input configuration, just to get my default, nothing special PS/2 keyboard up 
and running. Oh, and I didn't even have my not so fancy boring default PS/2 
mouse configured then. Guys, being able to configure everything is nice, but 
with the 2.5 kernel, things are definitely getting out of control IMHO.

This is potentially becoming a FAQ...  I ran into this too, as did

I wont, as long as you don blame someone who -to prevent buggy config files- 
downloaded a fresh 2.5.45 kernel, patched it with the bk-1 update and ran 
make menuconfig after that, of copying .config files.

Too bad you don't have any suggestions. I completely agree this should
be simplified, while I wouldn't be happy to lose the possibility of not
compiling AT keyboard support in.

Well, why can't it be enabled by default? Other options are as well, and it's
IMHO sane to enable keyboard and mice support by default. It should clear up
the initial confusion as well.

I think that these options should be enabled by default:

[Userland interfaces]
	Mouse interface
		Legacy /dev/psaux (?)
			(I suggest to make this non-default in 2.7, but maybe
			 we want shorter transition period?)

[Input I/O drivers]
	Serial i/o support
		i8042
		Serial port line discipline

[Input device drivers]
	Keyboards
		AT keyboard support
	Mice
		Serial mouse (?)
			(..or maybe not, this is really not so common as PS/2
			 lately)
		PS/2 mouse

I think that those are absolute minimum and if anyone will want to have any of
these explicitly off, he's more likely to know where to turn it off, rather
than vice versa.

All the needed options ARE enabled by default. (check arch/i386/defconfig)

What about:

<*> serial i/o (mouse, keyboard...) support"
  <*> PC PS/2 and keyboard controller (i8042)
    <*> PS/2 mouse support
    <*> Typical (AT) keyboard support 
  <*> Serial port (COM) <something> support
    <*> Serial port (COM) mouse support
  [*] Advanced keyboard support
    <*> Other keyboards here
  <*> [the other Things]

Yes, it confuses people who only wants a mouse working. 
Still i think it's better than selecting the driver controller
and after that selecting the device controller (if i'm understanding
the current menu ;) BTW, we'll never be able to put a <*> Mouse support
so i think that this is the best way. 


Also, the current menu has some things that i dislike ;)

- Please, don't use names such "i8042 ". Most of the people
  (even people in this list i guess) didn't know what
  a i8042 controller is until they had to configure that ;)
  "Help" is the right place for explainig that i guess ;)

- Replace "mice" by "mouse support" or something. English isn't the only 
  language in the earth. Many people think that the plural
  of "mouse" is "mouses" ;)

- In the current menu, you can disable the i8042 thing and you still can see
 the [*] Keyboard entry alone.
 






and another (crap) suggestion could be to put the pc speaker support under a /proc/something
and remove the menu entry ;)

Why not set the default option for AT Keyboard support on i386 platforms to 
"Y"?

Correct me if I'm wrong, but we're here to work out the problems. That's 
one of the major meanings of "development", in my experience.

I was bitten too: I loaded my 2.4.19 configuration and looked through most 
options, but I overlooked this keyboard/mouse thing. I think it's not 
turned on by default if you load an existing configuration, which is 
probably not what we want.

This is true, but if you are going to make a report, make a 
report, don't advocate changing something which works for 
most as it stands.  From the subject, one got the idea that 
people wanted to do some willy-nilly rearranging of the 
configure options.  The real issue here is that you really 
should *not* be copying 2.4 .config's over to a 2.5 tree. 
That way you'll be forced to go through all the options and 
get the proper "default" options for your platform enabled 
automatically.

Nicholas

Something I have been thinking about for a while is a quick-config option 
(that sets some defaults that hold for 90% of the systems), or an expert mode 
that shows extra options. Though I understand that this is hard to do, and 
much hardware differs, I think it can be done for some basics like keyboard, 
mouse, USB and stuff.

Yes, this will cause your kernel to be bigger than optimal, for some drivers 
will be compiled in that are not used on your system. But if you want you can 
optimize things away after clicking <set defaults for standard IBM PC>.

If this idea is not blown away immediately, I'm willing to work this idea out 
a little, though I can understand that people call me an idiot...

Why souldn't I be able to do that? I was hoping that options missing from 
the loaded config would be set to the default value, which in the case of 
standard AT keyboard and PS/2 mouse is "yes, of course I want that".

How long will it take to go through all the options, your old config file 
at hand, and check that everything you need is there? How easy would it be 
to make a mistake?

Documentation isn't enough. It _has_ to be made simpler.
Its obvious that this is the #1 stumbling block to a 2.5 virgin right now.
I fell over it myself when I merged it, as did Linus I believe.
It's just not obvious enough.

Having it documented obviously isn't enough too. I covered this in
the document[*] I wrote last week, which got ~3000 direct hits, ~7000
or so on Linux-today, and god knows how many elsewhere.
(Either that, or my description of the problem sucked).

So here goes the suggestion:

The config gets a version-Tag.

Changes before the second dot in the version print a warning that you
should not copy configs between major-versions. (Maybe it is better to
default to exit with the warning and an option to override the exit.)

Only configs without a version-Tag are tricky. Maybe there is a good(tm)
config-option that can be used to guess if the config is from the
current major-version (=2.5). All other configs are "old(tm)".

This is a general merging issue. I personally didn't get affected (because USB 
only is good), but it was a big problem for 2.4.19-pre10, when HID input 
support became optional (so you can have HID for an embedded USB UPS server, 
without getting bloat).

The idea of using a kernel revisioning system is good, but things change 
between any two kernels (2.4.19-pre9 and 2.4.19-pre10 in this case).

Suggest that the kernel .config should be revisioned, and if the version 
doesn't match, make $BUILDTARGET (eg bzImage, vmlinux, modules, whatever) 
should not run. make install and make modules_install shouldn't run either.

Instead, if the version differences are minor (definition TBA), then make 
[|x|menu|old|m]config should copy the old .config to an alternative name (eg. 
.config-previous) and then for each option, we should pull from 
.config-previous, then def-config (if no entry in .config-previous), which 
we'd then have as a default. and allow the user to override.

Also note that this will NOT solve the problem described. When you move 
functionality into an existing section, which is turned off, you have to 
check every option. Consider the impact of creating a "make kernel boot" 
option three levels down in the AX.25 code. 99% of kernel builders wouidn't 
see it. Generally you only get this level of breakage in unstable series, so 
people need to rebuild their config from scratch anyway. Also, the intent of 
some options changes (consider those that no longer need any SCSI, because 
their IDE CD-RW device is now native)

Fundamentally, if you don't know how to build the configuration, this is a 
good time to learn, even if only by trial and error.

Yes, but if this will be in the Kconfig as well (I mean adding "default y"
lines, I can make a patch, if there's a desire), it will be offered as default
even when doing make oldconfig, which is what most of the people is going to do
(not make defconfig, most of people doesn't even know it exists and the rest
probably wants to configure 2.5 based on their 2.4 configuration anyway).

Now all you need is the users to know "make defconfig". I compile kernels since 1.2.13, but I didn't know the option till today. Sure, my fault, but I'm sure I'm not the only one.

Detail: IMHO the USB keyboard and mouse support should be on, and DRI should be enabled for all video cards, but that is a minor issue...

[PATCH] Sane defaults for the input layer configuration

[Petr Baudis]

  Hello,

  this patch (against 2.5.45) introduces sane defaults for the input layer
configuration. The most common options default to yes now, so that with simply
accepting defaults provided by make oldconfig, the 2.4 configuration can be
converted to 2.5 configuration while preserving the basic keyboard, mouse and
serial port support. This should prevent most users confusion when configuring
their first 2.5 kernel. Please apply.

Maybe we need some heuristics for "upgrading" old .config files in
the event of a "make oldconfig". They could be of the form of rules
like this:

CONFIG_obsolete1 && CONFIG_obsolete2 -> CONFIG_new1=y, CONFIG_new2=y

(In a separate file, and entries would be aged. Maybe config tools
could even walk users through this interactively, or flag settings
obtained this way specially, e.g. with a similing wizard icon ;-)
Maybe even add some descriptive text after the rule.)

This still doesn't help for hard to find or obscurely named options,
but at least people upgrading wouldn't be bitten every time something
is renamed or restructured.

This would only be helpful if you also had a description of what the
user is expected to change. (And once you have this, you might as
well automate the process a little more, as I've just described in
another posting.)

Just telling the user that there might be problems isn't very helpful,
in particular since most such version conflicts would be false alarms,
e.g. name changes of some obscure controller I don't have anyway. I
think most people are aware of the fact that "make oldconfig" may
produce nonsense, but it's still annoying if it does.

Another easy extension to consider: after "make oldconfig", print
the options that were found in .config, but which don't exist anymore.
I've actually proposed this already two years ago, see also

so while some people are attempting to "fix" this with
defconfig or mostlikelyconfig, I'd like to remind people
of the post-halloween doc from Dave Jones.  He addresses
this stuff in there.  Does it possibly need even more
emphasis there?  and stronger hints for people to at
least browse it before using 2.5.x for the first time?

Keep in mind that All the World's Not a PC.  No doubt those options are
enabled on the majority of kernels, by number, but linux supports many,
many types of systems, and I'll bet on fair number of them, it doesn't
make much sense to enable psaux mouse support!

So ... instead of saying `default y' for these options, how about saying
`default IM_ON_A_PC' where IM_ON_A_PC is defined somehow.  How, I don't
know; it could be a separate config question in a very obvious place,
perhaps itself having `default X86'.

Perhaps this should really be two flags, one IM_ON_A_PC meaning `typical
i386 pc with legacy devices', and the other, more general, being
something like IM_ON_A_WORKSTATION.  Then wierd things like psaux would
say `default IM_ON_A_PC', but more general things like keyboards would
say `default IM_ON_A_WORKSTATION'.

[Yeah, those names are sucky, I know...]

Thanks,

How about a PC subarch and turning them on by default for it?

Too bad you don't have any suggestions. I completely agree this should
be simplified, while I wouldn't be happy to lose the possibility of not
compiling AT keyboard support in.
