I was working on a module and need to be able to pass parameters to the module (preferably without having to compile them in). I noticed that the splash module does this (sort of) by having you load the image to display and specifying a "tag" for it so that the module can scan for the tag and find the image. I need to be able to pass more than a single configuration option though. I am considering putting all of the configuration options into a single config file, having that loaded into memory by the boot loader (much the way the splash module loads it's image) and then when the module loads it can scan memory for the configuration information and parse it. Is there a better way? Also, it got me thinking? Is there a way to "through away" the informaiton after I'm done with it. For example, in the splash module, once you load the image into memory, it's stuck there forever (ie. the "feature" that you can re-use it as a screen saver because it is still in memory). I was under the impression that we don't page kernel memory and thus the image is wired into RAM all the time (it will never be paged). Please tell me I'm wrong...because if not, doesn't this seem like a Bad Thing? Thanks for all of your help! By the way? Is anyone working on improving the splash module. With all the examining I've been doing of it recently, I would like to add the ability for it to scale the image to fit the screen size (rather than die of rimages which are too large). I was also thinking about adding XPM support so I don't have to use Windows BMP files :) anyway, those are just a couple of the ideas I thought I could implement to improve it, but I don't want to mess with it if someone else is already working on it.
