Hello!

I mentioned a few weeks back that I had some doubts on the difference between this override: SRCREV_kernel = "5821a5593fa9f28eb6fcc95c35d00454d9bb8624" and this one: SRCREV_kernel_juno = "5821a5593fa9f28eb6fcc95c35d00454d9bb8624"

Just to make sure I am looking at the right thing, can you please send a link to the actual recipe?

The following is the definition in the kernel recipe itself: SRCREV_kernel = "3d77e6a8804abcc0504c904bd6e5cdf3a5cf8162"

Turns out that with _only_ the first override in local.conf (without MACHINE), the kernel uses the right SRCREV but Perf uses the one from the recipe; I have to include the second override (with MACHINE) so that Perf can use the right SRCREV.

same here

Does anyone have a pointer that could shed more light on that subject?

Thanks and greetings!

Here's the kernel recipe:

https://github.com/Linaro/meta-lkft/blob/sumo/recipes-kernel/linux/linux-gen...

here, _kernel is not an override. You are using the SRCREV_FORMAT pattern. 'kernel' is coming from the 'name' arg in you SRC_URI.

So when you use SRCREV_kernel in local.conf , it's setting this variable for *all* recipes, including your kernel recipe. So your kernel recipe picks up the new value.

If you use SRCREV_kernel_juno, then 'juno' is an override for the variable called SRCREV_kernel.

Here's the Perf recipe:

https://github.com/openembedded/openembedded-core/blob/master/meta/recipes-k...

I am not too familiar with the perf recipe, but looks like it is setting: S = "${STAGING_KERNEL_DIR}" deltask do_fetch

So it doesn't seem to fetch anything, but it reuses the kernel source tree. So here SRCREV is 'irrelevant', I believe.

On local.conf: # Correct for kernel, incorrect for Perf: #SRCREV_kernel = "5117c0a56aeeb3ab18fb91bd611e739fec3df9c0" # Correct for kernel and Perf: SRCREV_kernel_juno = "5117c0a56aeeb3ab18fb91bd611e739fec3df9c0"

I don't understand why it would make a difference.. maybe with what I said earlier will shed some lights on your side?

Thanks and greetings!
