Apply the large patch first (mm) because chances are that the rtc-patch will fail here. If the rtc patch isn't against 2.6.8.1-mm4 then you may see hunks that fail. You'll need to fix these failures by hand. If you are not familiar with C code and/or kernel code, then this may be difficult for you to fix. It may be easier to have two source trees. Apply the mm patch to one and the rtc patch to the other. Then you can create your own patch that has mm and rtc merged together. This gives you a little flexibility as what the patches were applied to. Bitkeeper is good for this because you can clone trees easily, using hardlinks (see below). > > Or should I use a dfferent way? > > If I forget what patches I have installed how can can I see the list of > installed paches? :) Yes and no... Just using patch and diff you wont be able to see without keeping a directory of patches you applied to the tree. A utility called "Quilt" exists that allows you to push and pop patches. With this you can see what patches have been applied. Quilt is available via apt-get. This may sound really cool but be warned... Quilt is not something I would consider "for newbies". You should have a firm understanding of kernel patching first. http://packages.debian.org/unstable/devel/quilt There is also another utility called ketchup that may be of some help to you. This is an easy way to keep your tree up to date. It also supports the mm tree as well as a few others. http://kerneltrap.org/node/view/2976 You could also check out Bitkeeper. It's free of charge (providing you keep your source open) and it makes merging changes easier. It's also GUI driven. Here is an article on kernel source control that makes for a decent primer. http://linuxjournal.com/article.php?sid=6183 > > > Thanks and sorry for the log list of questions...I'm a Newb... > Lorenzo -- Eric Gaumer <gaumerel@ecs.fullerton.edu> -- Eric Gaumer <gaumerel@ecs.fullerton.edu>
