Layout of Freescale kernel git repository

PhilEndecott — Sat, 29 Oct 2011 16:30:35 GMT

Dear Experts, I am trying to understand the layout of the Freescale git kernel repository at http://opensource.freescale.com/git?p=imx/linux-2.6-imx.git . I'm not a git expert. I had hoped that by cloning that URL I'd get the most up-to-date i.MX kernel source. In fact, I end up with something that doesn't work because things are missing, including the early serial console (mxc_uart_early.c) and the AHCI (SATA) bus glue (ahci_sata.c). On the other hand, it seems that different "heads" in that repository, e.g. http://opensource.freescale.com/git?p=imx/linux-2.6-imx.git;a=tree;h=refs/heads/imx_2.6.38_11.09.01;hb=imx_2.6.38_11.09.01 do include these things (though I've not yet tried to build one). But that's (presumably) 2.6.38. So, what's going on here? Is it just my lack of git skills that are making this difficult? Thanks, Phil.

The git repository is based on the mainline kernel, so you will see different tags and branches that pertain to the mainline only (there is little mx5 code there).

You are right, you will need to check out the different mx* tags. They correspond to the different releases.

right, do something like

git branch -a

git checkout -t origin/imx_2.6.35_11.05.01

will get you to the imx branch

it pains me that i could not reply via email, each time i have to visit the forum to reply, very inconvenient.

> git branch -a > git checkout -t origin/imx_2.6.35_11.05.01 Well I did something like that. (Except that would be the 2.6.35 kernel. I want something new.) Can anyone recommend any git documentation that will teach syntax to that level of sophistication? I have encountered various git books, which stop short of that sort of thing, and the man pages, which just define things in terms of other jargon...

Pro Git (http://progit.org/book/) is one of the best resources for beginners. The man pages might be difficult to grasp at first.
