If it is set to the empty string, a directory by the name of meta should exist in the machine branch and should contain a complete set of meta-data. 27415 1 dvhart 2012-11-13 21:51:17 +0000 For example, the comments in kernel-yocto.bbclass::do_kernel_checkout() suggest that a branch is required. 27424 2 bruce.ashfield 2012-11-14 02:37:39 +0000 KMETA definitely is not required in the current code, every linux-yocto-custom is running with an empty KMETA variable. I'm not sure what you are seeing in do_kernel_checkout(), but the only reference to KMETA is protected: if [ -n "${KMETA}" ]; then git branch -a | grep -q ${KMETA} if [ $? -ne 0 ]; then echo "ERROR. The branch '${KMETA}' is required and was not" echo "found. Ensure that the SRC_URI points to a valid linux-yocto" echo "kernel repository" exit 1 fi fi .. so if it's empty, it won't fire. If KMETA is empty, the tools expect nothing, and meta doesn't need to exist in directory form. Maybe our notes are messed up on this defect, but I don't think there's anything to document for this one with respect to branches and directories, but I could use the defect to document how to switch/use KMETA. Does that sound ok ? 27437 3 dvhart 2012-11-14 16:52:54 +0000 Perhaps just the comment then? # we can fix up the kernel repository, but at the least the meta # branch must be present. The machine branch may be created later. Maybe just something simple like "but the meta branch must be present if KMETA is defined" or similar. People coming up to speed on tooling are likely to read the above and assume a KMETA branch is required. 27438 4 bruce.ashfield 2012-11-14 16:59:43 +0000 That's reasonable .. I've modified the comment locally and will send it out with my next merge request. 27827 5 bruce.ashfield 2012-11-29 19:16:25 +0000 merged to oe-core.
