Hi folks,
Koen reported that with a recent change to meta-minnow where
LINUX_VERSION = "something" changed to LINUX_VERSION_minnow =
"something" (which was a good change), the result was that the version
of the linux-yocto kernel packages for an unrelated machine in another
layer went backwards, because the value that was previously leaking
over into that machine's kernel recipe wasn't anymore.
This in itself is OK, since the change was to make the append set the
variable correctly. However it prompted me to look through meta-intel
to see how we're setting LINUX_VERSION. I see there are a number of
bbappends for
linux-yocto*
recipes that set LINUX_VERSION with no machine override; we need to
stop doing this. I can throw together a patch to fix it, but we'll also
need to make sure new BSPs added in future use overrides as well. Any
suggestions on how to handle the latter? Is this a documentation issue?
I've already asked Nitin to make this change across meta-intel and have
corrected patches that have been coming in without the MACHINE override.
So yes, we're on it.
As of now, there is no such issue in meta-intel layer. All the LINUX_VERSION
Variables got overrides recently.
I suppose this should be added to the linux kernel development manual.
Right.
Scott, can you check if any of the manuals mention LINUX_VERSION
without overrides such as LINUX_VERSION_minnow. If there is any that
need to be changed.
I am noticing that the reference manual, and BSP guide both need this change.
Bruce,
This file should change too:
meta-skeleton/recipes-kernel/linux/linux-yocto-custom.bb
I'm hunting down some other issues with configs and boards at the moment.
This is where I say "patches are gladly accepted" :) I'll ack anything
that is sent to the list.
Bruce
Thanks,
Nitin
