[linux-yocto] kernel-yocto: validate_branches questions

Mon Feb 17 15:52:48 PST 2014

I have some questions regarding creating a recipe for a kernel build.  Specifically I am having troubles with the validate_branches (kernel-yocto.bbclass).  I have the following set:
KBRANCH = "axsb/axsb_dra7xx-evm_6_03_00_01.XSE"
SRCREV_machine = "717bdd79798d9fa41bc8bd2d089b17ebb52819cd"
SRCREV = "717bdd79798d9fa41bc8bd2d089b17ebb52819cd"
KMETA is not set.

The output for the verify_branches indicates that two different branches have the same commit (717bdd797)--my KBRANCH and another (fred/xsrapid-demo-glsdk-6.0.3.0).  However only the one I specified in KBRANCH contains the defconfig that I need, the other does not--neither does master.  The other potential issue is that the other branch head is not 717bdd797.  When looking at the code I can see the file exists from the normal fetch and unpack.  It is when the validate_branches does the "git checkout -q master" that it checks out master and the file is obviously gone.  The next for loop checks for the head commit of the braches containing my commit and if not head it switches to them.  This is the part that is especially troublesome.  It switches to the wrong branch and then since I have no KMETA configured exists out.  My questions are:
1. Why does it not just switch to the KBRANCH I specified originally?  Isn't that the point of KBRANCH to ensure the correct branch is used.
2. What is the difference between SRCREV and SRCREV_machine?
3. If I comment out the KMETA check resolves the problem.  The code that follows reverts back to the KBRANCH as I would hope.  Is this the root of my problem?  If so, what is the use for KMETA? (Can't find much of anything online) In much of the bb code it can be unset and is assumed "meta".  While, this routine may seem to expect something.

Any help or insight would be MUCH appreciated.
