+Subject: [PATCH] debugss_kmodule: kernel 6.11 changed return value for remove
+ slot
+
+In kernel version 6.11 the function footprint changed for the remove
+slot to return a void instead of an int. [1]
+
+Add ifdef checking code to look for kernel version and pick the correct
+return code.

Re: [meta-ti][master/scarthgap][PATCH 1/4] linux-ti-staging: Add v6.12 recipe

[Denys Dmytriyenko]

This might have been easier to review with --find-copies-harder flag...

And I was wondering if setting KERNEL_PATCHES would be cleaner in the 
corresponding recipes, instead of globally in ti-kernel.inc?

Same comment with --find-copies-harder, although the recipe itself is quite 
smalle, so the diff could even be larger...

Is this specific to 2024.10? Should it be added in the recipe, not .inc?

It might be.  I'll look into it and send another patch to clean it up if 
it makes sense.

Previous linux-ti-staging-rt recipes [1] used a specific branch
"ti-rt-linux-6.1.y" obtained by merging the TI vendor "ti-linux-6.1.y" branch
and the preempt-rt v6.1-rt branch [2].

  BRANCH = "ti-rt-linux-6.1.y"

Since preempt-rt is now merged in the kernel 6.12, indeed we can use the same
kernel sources with a specific configuration fragment (hence there is no
ti-rt-linux-6.12.y [3]).

But the preempt-rt project still maintain a v6.12-rt branch with all remaining
patches [4]. Actually the project still recommend to apply the latest PREEMPT_RT
patches [5].

Should the linux-ti-staging-rt recipe follow the preempt-rt stable branch as before?

Porting existing project (kirkstone 6.1 -> scarthgap 6.12) using
linux-ti-staging-rt recipe, users may expect that this recipe still use the
preempt-rt stable branch.

Thoughts?

Indeed when we started 6.12 LTS baseline migration, Since PREEMPT_RT is 
part of mainline we have started using a unified kernel branch ( With 
config fragment switch) to build RT and non RT baselines.

The preempt-rt project didnt have a 6.12 branch till august in the year at
https://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git/

The development and hosting of v6.12-rt including additional on the fly 
features is something new and i hope it continue with next LTS (6.18 as 
well)

As you can see with 
https://patchwork.yoctoproject.org/project/ti/list/?series=41242 , we 
are in process of switching development with master and next LTS yocto 
to 6.18 baseline and we are assessing how and if RT need to be 
maintained as linux-ti-staging-rt-6.18 recipe based on the feature 
differences in v6.18-rt vs mainline kernel.

6.12 combination with scarthgap is in maintenance mode at this moment.
The evaluation of linux-ti-staging-rt moving forward will be for master 
and wrynose in 2026.

Preempt-rt issues are fixed over the time, especially for the 6.12 kernel since
it's the first release with preempt-rt included. But Preempt-rt specific changes
might be too risky to backport to linux-stable branches. We can hope that
v6.18-rt will never exist but who knows...

In other hand, it's only a few dozen of commits (as of today), some of them not
related to TI SoCs.

The linux-ti-staging-6.18 is too recent, some TI specific changes (like the
DMA-BUF support in remoteproc) is not yet rebased:

https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/commit/drivers/remoteproc/remoteproc_cdev.c?h=ti-linux-6.12.y&id=3119d723957038270225867130678d76081dee0c

Ok.

kernel 6.18 was released only few weeks ago (uboot 2026.01 is not released yet)

We will consider switching to Wrynose as soons as the TI-SDK will be released.

Yes , But the fixes should be going thru the v6.12 stable tree IMO and 
v6.18 stable as well moving forward.


  But Preempt-rt specific changes

I hope the same as well. The other reason we are monitoring v6.18-rt is 
for arm32 platform support to mainline
Reading FWIW :

Agreed, We are evaluating these fixes and will bring up with real time 
linux and keep you posted here once analysis is completed.
FYI : TI is a member for RT Linux https://realtime-linux.org/membership/

Yes, We have just started LTS Migration process and will migrate all 
features/drivers from January to 
https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/log/?h=ti-linux-6.18.y 
(Including the remoteproc changes you mentioned)

for uboot, currently pulling the latest rc tag to 
https://git.ti.com/cgit/ti-u-boot/ti-u-boot/log/?h=ti-u-boot-2026.01 , 
But the plan is to pull till final 2026.01 tag is made and then port the 
delta patches from upstream backport and ti-u-boot-2025.01 branches.

Thank you that will be good. Till Wrynose is tagged, We will continue to 
use Yocto master with 6.18 and 2026.01 branches for migration effort.
