what means the EXTRA_KERNEL_SRC_URI variable, if anything?

perusing a BSP package handed to me by someone else and in their
recipes-kernel/linux/ directory, there's a custom kernel .bbappend file with the line:

EXTRA_KERNEL_SRC_URI += "file://kernelmods.scc"

i am unfamiliar with that SRC_URI-related variable, and i don't see it anywhere under the numerous layers i have checked out. is this some legacy/deprecated variable? i don't know what to make of it.

I'm guessing that BSP was created/packaged by Wind River :) That variable shows up in the linux-windriver kernel recipe, which is based on linux-yocto.

It was simply a way to have a variable that could be used, without requiring direct manipulation of the SRC_URI .. since if a direct assignment had bee done to SRC_URI "good things" got clobbered, and "bad things" happened.

I'd suggest ignoring it (except perhaps in the context of what you are using), since it is specific to that kernel, and something that will go away over time.

oh .. and if the BSP wasn't a Wind River one .. I have no idea ;)

Cheers,

Bruce

that is, of course, precisely where it came from -- thanks for
clearing that up.
