Need advice on tracking down "-dirty"

Need advice on tracking down "-dirty"

[Spriggs, Jim]

Hi Guys,

Using poky dizzy with meta-altera (from OE), and trying to implement a simple loadable kernel-module by following the method outlined  in Lab3 of  https://www.yoctoproject.org/sites/default/files/kernel-lab-1.6.pdf.

I'm doing an "rm -rf tmp" before starting "bitbake virtual/kernel  my-image-recipe".

The build seems to work just fine: the kernel-module-xxxx-1.0-r0.machine.rpm appears as expected under .../deploy/...

The package installation task fails, however, with:

    error: Can't install kernel-module-xxxx-1.0-r0@machine : no package provides kernel-3.15.0-00184-g5ae31a7

and indeed, the kernel packages available in .../deploy/... are:

    kernel-3.15-r1.machine.rpm
    kernel-3.15.0-00184-g5ae31a7-dirty-3.15-r1.machine.rpm
    kernel-dev-3.15-r1.machine.rpm
    kernel-image-3.15.0-00184-g5ae31a7-dirty-3.15-r1.machine.rpm


Yet "git status" reports "nothing to commit, w.d. clean" for both the main poky tree and the meta-altera sub-tree.

So I guess the n00b needs a clue about how to find out why and where the dirty-flag is getting set?

Thanks for listening!

By this, do you mean the kernel source tree ? Or the layers ?

I haven't looked at the kernel recipe you are using, but PV
and the git hash you have in those package names is coming from
the kernel source directory.

It is there that you'll likely find un-commited changes, and what
is triggering the -dirty flag to be captured.

Hi Bruce, List

@Bruce: many thanks indeed for your prompt reply and very helpful clue!

It turns out "-dirty" has nothing directly to do with my own recipe at all.

It appears as soon as I specify 'KERNEL_PROVIDER = "linux-altera"' in local.conf, instead of allowing the meta-altera layer's default (which is "linux-altera-ltsi") to go through.
"linux-altera" currently pulls in kernel version 3.15, whereas "linux-altera-ltsi" pulls in 3.10.

I'm using "git clone https://github.com/kraj/meta-altera" to get the altera layer.

Can anyone suggest why 3.15 should (apparently) be "dirty" straight out of the repo?
Is this actually expected behaviour?
Alternatively, what it is that I'm failing to understand about the whole yocto/bitbake mechanism?

Many thanks for your collective patience....
