List-Id: Help regarding installation and common use of Xenomai List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: xenomai@xenomai.org This is a multi-part message in MIME format. --------------010502050607030105080805 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit I have a question regarding the ipipe patches. There appear to be three places to get them: 1) Contained within the Xenomai tar 2) From the gna adeos downloads page 3) From the DENX ipipe git I have been getting the patches from the Xenomai tar, but I ran into a problem, because I needed to use a newer version of the kernel, to get some other powerpc features. The patch from the Xenomai tar was not new enough to apply cleanly. So, can I use the gna-ipipe patches with the Xenomai tar, or am I better off extracting a patch from the DENX ipipe git? Even if you recommend the gna-ipipe patches, I'd like to know what git commands one would use to extract a patch file from the DENX ipipe git. I assume it is some variant of git-diff, but I am still learning git, so a hint would be appreciated. Also, I'm not clear on the best way to set up my local git tree. Do I clone from linux-2.6-denx.git or ipipe-2.6.git ? Whichever I clone from, do I create branches to track both of those remote git repositories? Once I apply the ipipe patch to my local git tree, do you recommend committing that, perhaps on some other branch? I guess this boils down to: what is the "best practice" for setting up a local git given that I want Xenomai plus a very recent kernel. I also want to be able to apply updates for ipipe, Xenomai, and the kernel, and I'm not clear on how that interacts with the ipipe patch model. Do I back out one ipipe patch to apply a newer one, or somehow create a diff between two patches? I'm so confused... :-) TIA for any guidance you can offer, Steve --------------010502050607030105080805 Content-Type: text/html; charset="utf-8" Content-Transfer-Encoding: 8bit I have a question regarding the ipipe patches.  There appear to be three places to get them:
