Hi folks,
For my EndThesis, in the Niederrhein University of
Applied Sciences, I've almost finished a framework
that generates a .config file based on the target
system.This program should help people to generate a
linux kernel Config without spending a lot of time at
the configuration.
The basic idea of the framework is, that you can
specify in the Kconfig files a script which
auto-detect if the hardware involved in this option is
present or not (the script reply 'y' or 'n'). It's up
to the interface to choose what to do with the answer.
This framework is now in its test stage. It works on
my Acer Laptop(TM291LMI with Pentium M and Radeon
9700). That means, that the framework is functional
but additional scripts have to be written for other
type
of hardware/functionality (far away from completed).
The code of this framework has been splitted into six
patches (to be posted following to this mail):
- conf.c and expr.h
- parser
- makefile
- rules
- kconfigs
- documentation
To try it, just patch a 2.6.13 kernel with the patches
following this
mail and set the scripts as follow: chmod u+rwx
scripts/kconfig/rules/*
Then, just type: 'make autoconfig' or 'make
autochoiceconfig'.
The 'autoconfig' will detect your hardware and
automatically include in the kernel whatever hardware
is detected. The 'autochoiceconfig' will let you
choose to include the feature or not when a hardware
is detected.
Any comments and suggestions are welcome !
Regards
Ahmad Reza Cheraghi

Hi
I wrote this Framework for making a .config based on
the System Hardwares. It would be a great help if some
people would give me their opinion about it.

I'm a power user and of course I can do make menuconfig, but it would be useful when building a kernel for new hardware for example. Currently that involves looking at dmesg output to figure out the correct options; this would provide a nice base config to work with and reduce the amount of effort.

I second that. Unlike majority of users I suppose, I upgrade the kernel often and I am on the bleeding edge (laptop user with some drivers still being in development). Even with oldconfig it's easy to miss a useful driver (sometimes there's no help or the volume of new options is too large). Something that can do the hardware detection, then maps that to drivers would be very useful. -- Marek W Send instant messages to your online friends http://au.messenger.yahoo.com ^ permalink raw reply [flat|nested] 47+ messages in thread

In attribute "name" the name of the menu should be written. + Attribute "must_have" shows the min. number of option, that in a menu should be choosen for a proper Kernel. + <menu> can contains options or submenus(the same as <menu>). + +<option name="option name"> rule </option> + In the attribut name the option name should be written. And the contain of the Option Tag + is the name of rule that belongs to that option. + +example: + +<rules> + <menu name="Networking support" must_have="1"> + <option name="Networking support">egrep1.pm "Network|Ethernet"</option> + <menu name="Networking menus"> + <option name="Packet socket">yes1.pm</option> + <option name="Packet socket: mmapped IO">yes1.pm</option> + </menu> + </menu> +</rules> + + +How to make a rule +******************* + +A rule can be either a script or binary or... The main job is to +give out an answer to stout for the actually option-question, it doesn't matter +how. + +We have three types of answer: + +sym-answers: either y, n, m or \n. + +string-answer: can be maximal 128 characters + +option-answer: By the manual configuration normally you have to type an number + but a rule for an option should give out an y, if it want to be choosen. + + + + + +For example: the option is "Networking Support" + the program looks in the our list (which is called rules_list) + to find the "Networking Support" and if this option is in there, + a certain script (which we call it a rule) will be executed. + In this example the script name is hw_grep1.pm which + reads a given Parameter and searches for this Parameter, + lspci and dmesg with the help of grep. In this Case the Parameter + will be "Ethernet|Network". + + hw_grep1.pm: + + $found=''; + $found=`lspci | grep "@ARGV"`; + if($found ne '') { + print("y\n"); + } + else { + $found=`grep -E "@ARGV" /var/log/dmesg `; + if($found ne ''){ + print("y\n"); + } + else { + print("n\n"); + } + } + 1; + + + + + + This script checks if there is an Ethernet or + a Network card on the target System. + If it is true, it gives in this case a 'y' to stdout. + And for some options there can't be any script-rules, for instance software such as FTP or TCPIP etc..., + those question either get answered as 'build in' or as 'module'. + !! the answers must always have a '\n' at the end + +The rule-binary should be copied in the directory <KERNELVERSION>/scripts/kconfig/rules/ + + + +Messages: +******************* + +When the amount of needed Options in some menus are not choosen, +messages will be given out in the stdout, at the end of the configuration. +Containig Name of the menus. + +This can be happen: + +1. if for some options they rules are not applied. The reason for that is for some Hardware Option there is no rule. + +2. if your System doesn't support the Hardware i.e. you don't have an ethernet Card. + +In this case either your upgrade the autoconfig with rules or your contact me. + +If you are getting messages please include the following information: + +1. a copy of your lspci, /proc/cpuinfo and /var/log/dmesg + +2. a copy of your messages + + + +TO DO: +******************* + +1.

Isn't this exactly what > you get with a fully modular config and hotplug? Not so much the kernel. When compiling the kernel I'd prefer not to waste time and space compiling the 100+ modules I will never ever use on my laptop.

The good thing about lspci (comparing to the others Hardware detection like kudzu or discovery) it not only uses the /proc files for getting the Hardware information it also grabs its information directly from the I/O of the Hardwares. But it lacks of getting alls the Hardwares e.g. CD-Rom, floppy... It would be great if there is a Programm that gets all the Hardware information directyl from the I/O independent from the Kernel-installation. __________________________________________________ Do You Yahoo!?

I agree that make oldconfig shouldn't do this type of thing, but that requires that youhave an existing .config for the box. if you do a make autoconfig you are explicitly asking the software to do this for you.

Isn't this exactly what > you get with a fully modular config and hotplug? I happen to be one of those crazy people who believe that there are advantages to building non-modular kernels. 1. they compile faster 2. they use less memory (if tightly configured) as each module loaded will average a 1/2 page of wasted memory 3. it's far easier to moveone file around then a file and a directory tree of modules 4. the non-modular kernel will be slightly faster (all calls to modules must be far calls, if it's not modular the compiler can optimize some of the calls) 5. once kmem and mem can be made read-only there is a security advantage in not having kernel modules available (yes the machine can be rebooted into a new kernel, but that's easier to detect then a module getting loaded) 6. the kernel takes less space on disk (matters in embedded devices and other places where your media is small) none of this matters if you're dealing with a large desktop system that you are installing from a series of CD/DVD disks from a top-5 distro, but that's not the entire world note that a good autodetect routine will have no impact on the kernel once it's compiled, it just generates a .config file. I believe it makes more sense to have this be part of the kernel source distro then a seperate project as it needs to have a lot of knowledge about what a particular kernel supports and that's going to change from release to release.

If you do this in the kernel source directory: make allmodconfig that makes a kernel with all possible configure options that can be built as modules enabled. make install and you have a couple of nice files in /lib/modules/(version)/modules.*map -rw-r--r-- 1 root root 73 Sep 14 23:15 modules.ieee1394map -rw-r--r-- 1 root root 132 Sep 14 23:15 modules.inputmap -rw-r--r-- 1 root root 81 Sep 14 23:15 modules.isapnpmap -rw-r--r-- 1 root root 7834 Sep 14 23:15 modules.pcimap -rw-r--r-- 1 root root 43 Sep 14 23:15 modules.seriomap -rw-r--r-- 1 root root 80010 Sep 14 23:15 modules.usbmap the usual favorite of mine is modules.pcimap, which, when compined with lspci can give you the proper module for your pci device.

For that reason I thought the best way is: using the option-name given out, by make menuconfig or make config... And you can even easily upgraded it if the option-name(for the same Hardware) is changed by a new Kernel. By only putting this new option-name in the rules_list with the same rule. b) sometimes > two drivers do the same > thing, but if enabled together will cause kittens to > cry and babies to pull > flowers.

Yes your right. The idea(eventhuogh it is a dream) is that, this Framework might be hopefully in the future, a part of the Kernel. So it can be updated everytime before a new Kernel will be releases. > My 1.5 $denomination > Chris White > __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

I agree ! When compiling for a new platform you would like to have at least a minimal skeleton of the .config which is working for your machine and then add stuff like NFS, netfilter, and other stuff. Something like: make autoconfig ---> generate a skeleton (compile and run) make menuconfig ---> add the stuff you want (file systems, firewall, ...) However, if the "make autoconfig" target generate nothing but a bare minimal .config which is fitting exactly your hardware, which would compile and run on your platform (with a stripped down network layer, only one file system, etc). Then I would like to have this. > Currently that involves looking at dmesg output to figure out the correct > options; this would provide a nice base config to work with and reduce the > amount of effort. Yes. Especially for strange platforms where you usually end-up with a try and error methodology... (yes, I got a Transmeta Crusoe Sony Vaio C1-MZX once ! :)).

I often have to set of machines with very different hardware.

I'm asking because the major part is still ahead of you and I'm not sure how much further you want to take it take it beyond your university project. The basic problem is that maintaining the bulk of autoconfig information in a separate file is not feasible, it would be a nightmare to maintain. This means it would be better to integrate this information into Kconfig and define interface so that external program/scripts (preferably shell instead of perl) can use that to configure the kernel. A simple example could look like this: config FOO bool "foo" def_auto y Internally this would become: config FOO bool "foo" if !AUTO_CONFIG default y if AUTO_CONFIG AUTO_CONFIG could also be used to ask some simple questions for things that can't be automatically configured and these answers can be used to adjust other parameters, e.g.: config AUTO_SERVER bool "Configure for a server" depends on AUTO_CONFIG config BAR bool "blah" def_auto AUTO_SERVER Driver configuration might look something like this: module foo tristate "foo support" Kconfig would generate a config symbol FOO and a Makefile entry for this. Autoconfiguration could now either look like this: module foo pci_map VENDOR DEVICE [...] or we just an option and extract the data from the source: module foo option pci In either case Kconfig would feed this data an to external program which matches it with the existing data and returns the matching config symbols (the matching process would be pretty much like what hotplug already does). As you can see a proper integration would require a bit of work, I can help with Kconfig related parts, but it needs integration into several systems. The end result would be much more useful. Instead of maintaining another file, the data is shared and automatically updated by the relevant system. bye, Roman ^ permalink raw reply [flat|nested] 47+ messages in thread

Each script output y, n or m. But, it means a hell of scripts (except if we can pass arguments in the auto field: auto "detect-foo-script card-XYZ release-32-or-higher"). This scheme seems much simpler to me (and yet not restrictive at all). Of course, each script might have to ask few questions to the user as: Do you want this FOO support ? [y/m/n]: Or (when no module option): Do you want this FOO support ? [y/n]: When the feature is not detected or no field "auto" is found, the feature is simply skipped silently. I think this way is minimizing the foot print on the code and yet is quite powerful. Moreover, you can add the auto-detection scripts without interfering with the rest of the building system. The target autoconfig will just be more and more efficient as long as more scripts are added.

To pass argument it is not a problem we do it like we passed the rules in the rules_list(see the function exec_rule in auto_conf.c ). The lex parser has to be expanded in that way that it gives everything written after "auto" to the autoconfig. config FOO bool "foo" auto "detect-foo-script" So the new programm will work like that: It goes through are the Kconfig as usual. For any Option that doesn't have any "auto" a '\n' will be given. If there is an "auto" it will execute the script that is written after it. I think it might work like that.

The main difference will be that the options without "auto" flag or where the script said "n" will be skipped. It will reduce quite considerably the number of questions. The algorithm is quite simple: If (no "auto" field) ---> go for the default If ("auto" field) ---> script gives n ---> go for "n" script gives y ---> ask for [y/n] script gives y/m --> ask for [y/m/n] That's all folks...

To pass argument it is not a problem we do it like we passed the rules in the rules_list(see the function exec_rule in auto_conf.c ). The lex parser has to be expanded in that way that it gives everything written after "auto" to the autoconfig. config FOO bool "foo" auto "detect-foo-script" So the new programm will work like that: It goes through are the Kconfig as usual. For any Option that doesn't have any "auto" a '\n' will be given. If there is an "auto" it will execute the script that is written after it. I think it might work like that.

Each script output y, n or m. Unless there is an example, which really needs this, I don't think this is a good idea. Mainly because I don't like the idea of running random scripts during the config process, I prefer to keep this a little under control. > This scheme seems much simpler to me (and yet not restrictive at all). > Of course, each script might have to ask few questions to the user as: > Do you want this FOO support ? [y/m/n]: This will almost certainly not happen. The autoconfig rules would also be useful in the graphical config front ends and something like this would prevent it. bye, Roman ^ permalink raw reply [flat|nested] 47+ messages in thread

Well, at the end you just want to have one .config file with everything inside. If I follow your logic we also should have a .fsconfig, a .netconfig, a .audioconfig, ... and so on. So, working on the .config seems nice to me. Simplicity is good ! ^_^ Regards -- Emmanuel Fleury A child of five could understand this.

It will be a hard also, for those Users which doesn't have that much experience for the configuration of a Kernel. __________________________________ Yahoo!

But I want to tell why I came to this Idea of doing that. As I was trying to configurate a Kernel for the first time but without any success. Then I thought about it, why this cannot be automatically. So for the first thought, my spirit of doing this, was for those who doesn't know e.g. what the option "Enable loadable module support" means and if they have to choose that or not. But right now I know that it is not possible to do all the things automatically(like the filesystem, Protokolls...). And that is the reason why I make a Framework, so everybody(I mean the experts) can give theire suggestion what isthe best way to answering, a optione like mention above comes, automatically. So if someone wants to use a new kernel didn't end up desperate and regrated using Linux(a new Kernel). Regards Ahmad Reza __________________________________________________ Do You Yahoo!?
