The basic idea is that yes, you should not ask about $(large number) of things to tweak the kernel to some specific application but by that same token you shouldn't have to change the code directly (as when the next update happens, it will conflict and maybe you'll miss the new place that value is used, etc). So what this does is try and provide a happy medium. If something is tweakable, say so when you write the code, provide a default and let people tune it if they need to. And while we're at it, lets make it easy to change any number of these for a specific use and let the user pick a new profile. The following is vs current 2.5 BK and has been lightly tested on PPC (and compiled on i386). This creates the default files for all current arches, and adapts ARM and ia64 as well to show how to override a generic param with an arch-specific one (and removes CONFIG_FORCE_MAX_ZONEORDER). It also doesn't currently modify every arch/$(ARCH)/Kconfig right now. I fully except that there would be additional arch-specific profiles added, so I don't think this should be asked in a more common file like lib/Kconfig or something. I don't yet do CFLAG changes as that will require a bit more work (CONFIG_xxx works now since we can directly include .config. For TWEAK_XXX to work some sed'ing will be required to generate a new file for scripts/Makefile.build to include), and there's no doubt many other things which can / could be tweaked.

The first section is for +how users can use the TWEAK infrastructure to make the kernel better fit +their custom application. The second section is aimed at coders to +suggest how to make use of this when writing new code, or reviewing +existing code. + + The TWEAK system was designed to be easy to use, and hopefully it is. +There are two types of tweakable parameters, generic ones and arch-specific +ones. Everything which can be tweaked, and is in common code is initially +defined in include/asm-generic/default_tweaks.h. There is currently another +file, include/asm-generic/tiny_tweaks.h which re-defines values found in +include/asm-generic/tiny_tweaks.h so that a smaller kernel image is produced. + It is possible that specific archs will provide additional, +arch-specific configurations. Which brings us to the arch specific portion. +Every arch has an include/asm-$(ARCH)/tweaks.h, which includes +, possibly other arch-specific tweak headers, and +. This file is also where arches can re-tweak +common tweaks if needed. For example, ARM and ia64 will redefine +TWEAK_MAX_ORDER as they, on a platform or arch-specific basis need a different +value. + The file is very important, as this is where +the per-user tweaking happens. This file is always included at the end of +, so regardless of what is in any other of the tweak headers +included, any value can still be overridden by the user. + + The TWEAK system should also be easy to use for the coders as well. +If some subsystem is using a constant somewhere, ask yourself if you could +see any reason that someone might have to want to change it. If you can think +of one, and this is common code, add something akin to the following to +include/asm-generic/default_tweaks.h: +/* In the foo subsystem, we use BAR to do baz. */ +/* Default: 16 */ +#define TWEAK_BAR 16 +/* Or even TWEAK_FOO_BAR, whichever makes sense */ +And that's it. If you know that it could impact size, or one of the other +existing set of generic templates, you can also change those templates: +in include/asm-generic/tiny_tweaks.h: +/* In the foo subsystem, we use BAR to do baz. */ +/* Default: 16 */ +#define TWEAK_BAR 4 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
