Nope. If it's a clean revert, I'll take care of it locally.

Thanks for taking a look. I'll follow up if something isn't clean
about the revert.

This is merged, that being said .. there are a couple of things that
could use a second set of eyes.

1) I had a preempt-rt conflict in fs/libfs.c. It looks like
scan_positives() was introduced. The merge picked up a conflict, when
really it should have just been the introduction of that new function
and a drop of the old ones. But again, a 2nd set of eyes to see if I
read it right would be nice.

2) there was a conflict in v5.2/standard/xlnx-soc in
drivers/tty/serial/uartlite.c. There's a minor change in the driver
unregistration. I resolved he conflict, but there now might be two
unregister calls .. and I'm not sure how well that'll work. I copied
Quanyang, to have a look and see if I got it right.

Cheers,

Bruce

It depends on what image you are building, etc. So there's no generic answer.

I did have a look at the kernel-module-split.bbclass, and I didn't see
an explicit RDEPENDS on the kernel-image, so it is something that
should be doable (to install them without installing the kernel
image).

The "traditional" way to do this is commented in the kernel.bbclass:

# Allow machines to override this dependency if kernel image files are
# not wanted in images as standard
RDEPENDS_${KERNEL_PACKAGE_NAME}-base ?= "${KERNEL_PACKAGE_NAME}-image"

So if you explicitly clear RDEPENDS_${KERNEL_PACKAGE_NAME}-base in
your kernel recipe (or a bbappend), it should at least stop trying to
install the image if kernel-base is being installed.

Cheers,

Bruce

It used to be the opposite. The boards only booted with this enabled.
So my worry about changing it globally is that I fix some boards, and
break others.

We can always just change the setting in the BSP .cfg's that we can
prove they build and boot.

Correct. It only has enough of the build artifacts to develop against the
running kernel, i.e. out of tree modules (either on the build host, or on
target).

The name is historical, and isn't aligned with any specific distro (i.e. no
matter what folks say, there is no agreed upon naming for these packages,
so rather than break expectations in the ecosystem, we keep ours as it was:
kernel-devsrc).

To keep it minimal, we do use a curated version of the source (just like
redhat, etc). Footprint is very important for that package.

That being said, I do have a patch that creates a 'linux-source' package
that is the complete source, but that is really only for reference and
isn't extensively tested for building/development. I'm not in a place that
I  can get that patch right now, but I can send it out a bit later today.

Out of curiosity. What is the use case that you have for the source ? With
that information, I can tweak what we are offering as needed.

Thanks for the resend. I had indeed missed this one.

It is now merged (it applies to standard/base, so I merged
it there).

Re: [linux-yocto] [kernel-cache yocto-5.2/master] [PATCH] ti-am335x: enable GCC -O2 optimization

[Bruce Ashfield]

merged.

We should also either have a plan to figure out the root cause
of this, or we should patch the Kconfig to be broken if enabled
.. that way we'll prevent others from turning it on by mistake.

It's a separate recipe. Not part of the bbclass. Build that recipe,
and install the package and you'll get what you want.

There's no bug. kernel-dev doesn't the kernel source by design. Yocto
/ oe has always had its own naming for these packages, and kernel-dev
is the images / artifacts and the directory structure. Now that
kernel-devsrc is available (it wasn't a few years ago), we actually
could remove those directories from kernel.bbclass to clarify things.

You want the kernel-devsrc package, not kernel-dev in this case.

I'll wait for comments on this patch.

I just wanted to follow up to say that I *think* that I have all of
the reviewed and ack'd patches merged now .. but gmail is doing some
very strange things and hiding replies to some of the threads.

So if you see something that is reviewed/acked and is missing, send it
again with a clear "v2" (or whatever version it is) in the subject.

These already seem to be in v5.2/standard/base (Signed off by you and
myself) .. was this sent in error ? or did gmail do something strange
and dig up old email for me and mark them as new ?

Although one of the two patches applies to v5.2/standard/base, I kept
them both together on the xlnx-soc branch.

I've dropped this from my pending queue. Can you send a v2 (clearly
marked .. these series are starting to get tangled) with the comments

That way, I'll know that I'm merging the proper version.

linux-yocto-dev is now 5.4, so all existing branches are gone, support
and work in -dev now needs to rebased and sent as pull requests.

Re: [linux-yocto] [linux-yocto preempt-rt v5.2][PATCH 0/1] kmemleak: Change the lock of kmemleak_object to raw_spinlock_t

[Bruce Ashfield]

I already have the latest 5.2 -stable and -rt under test, so I'll
finish those rather than merging this.

These are now merged.

Are these changes already done upstream, or applicable to upstream ? I just
want to make sure we aren't only fixes these in the yocto kernel when there
are other places that we can fix as well.

I've pulled the branch into linux-yocto v5.2/standard/bcm-2xxx-rpi.

I assume that this branch contains the contents of your other pull request as
well, so I haven't done anything more that fetch and merge what you have
in this request.

If that is not correct, send more patches and pull requests to the list.

My tree was in a slightly different state, so it was easier for me
to manually create the new branch, and then merge the standard kernel
BSP into it.

That included the patch you sent earlier, and I've cherry picked the
other from your github branch.

The baseline configuration looks sane to me (I checked for obvious errors and
non hardware configs).

So I've gone ahead and merged this to the 5.2 and master branches.

This is now merged.

Re: [linux-yocto] [PATCH] [for all x86 branches] x86/boot: Save fields explicitly, zero out everything else

[Bruce Ashfield]

Since this is destined for -stable, I'm not going to merge the individual patch.

I'm holding nearly all 5.2 updates until the last introduction issues
are fixed. By that time, I'll have the next round of -stable updates
ready to go as well.

Cheers,

Re: [linux-yocto] [kernel-cache master/yocto-5.0][PATCH] intel-x86: add MGA G200 series VGA support

[Bruce Ashfield]

Indeed. I appear to have messed it up .. I had a lot of merges to do

I assume that you still also want the linux-yocto-dev changes merged ?
That is mhy plan.

perfect. Sounds safe for standard/base, so I'll look at merging it there.

Sorry. I managed to miss this after my vacation. Once I have the
current critical issues in master (around the 5.2 kernel) sorted out,
I'll get this merged. I hope to have that done today.

Hmm. That wasn't on purpose. My builds ran overnight, so I'll have a
look and fix it up.

Hey Paul,

I was merging this tonight and ran into a nasty -rt merge conflict in
kernel/irq_work.c. Can you take a look and send a resolution ? When I
compared the 4.19-rt and 5.x-rt branches, I didn't see an obvious way
to resolve things.

I went ahead and cleaned up the commit log, since we never say "commit
 upstream", if "upstream" is not linus' main git repo. I've
pointed at modules-next, and hopefully it is well behaved and won't be
rebased.

I didn't see it in -rc5, so hopefully it makes it upstream soon.

Re: [linux-yocto] [PATCH 0/4] More security fragments

[Bruce Ashfield]

I've merged these to the 4.19/5.0/5.2 and master branches.

SRCREV updates will follow this week, once I get some more test cycles
completed.
