RT Patch Manager
This python script started life as a convenience script that would tell me when Ingo released a new -rt patch, since there have been times when Ingo churned out four or more -rt patch spins in a twelve hour period :).
The script presumes the existance of two directories:
- A Patch directory for storing the patch
- A Linux git tree from kernel.org
Here's the usage message:
$ rtpatch --help usage: rtpatch [options] <cmd> where [options] is one of: --gittree=<path> - specify git tree to apply [./linus-kernel.git] --patchdir=<path> - specify patch directory [./sources] where <cmd> is one of: check - get the latest version of the patch get - fetch the latest version of the patch apply - fetch and apply the latest version of the patch running with no arguments checks for existance of the patch
So, to just check the current version available:
$ rtpatch Available RT patch: patch-2.6.18-rt5
If you want to fetch this version of the patch:
$ rtpatch get
You'll see a progress bar while the script retrieves the patch and saves it in your current directory
If you want to track the -rt patches using a git tree, make sure you have git installed on your system, make sure you have lots of disk space somewhere, change directories to that place and type:
Then go away for a long time. When the command finishes you will have a clone of Linus's git tree and you're ready to fetch and apply the -rt patch.
Assuming that you are in a directory that contains two subdirectories named source and linus-kernel.git, you can issue the command:
$ rtpatch apply
This will fetch the current -rt patch to the source directory and will then apply the patch to the linux-kernel.git git tree, (assuming that the patch hasn't already been applied). Your git tree will end up with a branch that is named after the -rt patch (e.g. if you issue the apply command and the current -rt patch is patch-2.6.18-rt5, you will end up with a branch named v2.6.18-rt5 in the git tree).
