For patching the kernel, I did:
xenomai-3.1 on main ➜
./scripts/prepare-kernel.sh
--linux=~/Projects/linux-kernels/linux-5.4.93-ipipe
--arch=arm
--ipipe=~/Projects/linux-kernels/ipipe-core-5.4.93-arm-0patch
The config I'm using is multi_v7_defconfig modified a
little bit. The
same configuration was fine for Vanilla kernel using
the same version
(5.4.93), as I was pretending to compare both.
Toolchain I'm using, selected directly on
buildroot-2020.02.11 long
term is: Linaro ARM 2018.05
Okay, I used that defconfig during the port so there
shouldn’t be a problem. Let me try with my repos and
I’ll let you know shortly.
Ok, sure
Let me know if I need to change configuration on my side
from compiling it again.
-Greg
I built directly from the ipipe-arm tree, using Xenomai
3.1 ang gcc 10. Other than a few warnings that I'll
silence later everything built okay. Let me take a look
at the patch and see if something went wrong there. In
the meantime if you want to sync the ipipe-arm tree and
use the ipipe/5.4.y patch you should be able to build no
problem. In the meantime I'll look at the patch, but I
think our CI system uses the patch and hasn't seen any
build issues. If you could run your patch command again
with --verbose and send the output maybe that may tell us
something.
Thanks
Greg
Could the problem be related to the toolchain used (Linaro
ARM 2018.05)?
Another thing: when doing the Kernel configuration, I get
the warning:
*** WARNING! Page migration (CONFIG_MIGRATION) may
increase ***
*** latency. ***
But I'm not able to disable "Page migration", nor
"Contiguous Memory Allocator", in "Memory Management
options" menu.
About running with --verbose, I got:
xenomai-3.1 $ ./scripts/prepare-kernel.sh
--linux=~/Projects/linux-kernels/linux-5.4.93-ipipe
--arch=arm
--ipipe=~/Projects/linux-kernels/ipipe-core-5.4.93-arm-0.patch

Build system ready
Are you using a 32-bit arm compiler or the aarch64 compiler?
-Greg
I'm using a 32-bit compiler
Can you send me your build commands?
thanks
Greg
I'm using buildroot for building the image using the patched
kernel. I use the default configuration "make
raspberrypi3_defconfig" and setup the kernel using custom git
repository (patched kernel). I tried all latest toolchains
available in Buildroot, but I get the same errors when
building.
Thank you,
Gabriel Dinse
this may be a buildroot issue, can you build the kernel
directly with just patching and building the kernel?
-Greg
Could you please suggest what compiler I can use for compiling
it directly?
Gabriel Dinse
i use the arm one the is available on there site, I think it’s
arm-Linux-none-gnueabihf- , the Linaros ones also work pretty
well.
Greg
I started the kernel compilation directly, using
gcc-arm-10.2-2020.11-x86_64-arm-none-linux-gnueabihf,
multi_v7_defconfig applied, and I got exactly the same
"incompatible-pointer-type" error :(
What could I be missing? Maybe the kernel repository?
(git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git
<http://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git> )
The patch went fine...
Using Kernel 4.19.144, with ipipe matching this version, the
compilation was successful, but using 5.4.93 I'm not able to make
it work
Thank you
Gabriel Dinse
you can try the ipipe-arm repo directly. I’ll try the patch
tonight and see what happens. The CI should be using the patch, but
I’ll try directly.
Greg
I will probably continue using kernel 4.19.144 for now until I can
figure out what is missing on kernel 5.4.93 compilation.
But I have other question regardin rpi3 device tree. Ipipe patch for
kernel 4.9.51 has an addition of "bcm2837-rpi-3-cobalt.dts", while I
couldn't find it in more recent ipipe versions. How is the device
tree configured on newer ipipe versions (like v4.19.144 I'm using
right now) if I don't have a file like this.
Thank you
Gabriel Dinse
So the rpi3 device tree should be in the arm64 repo, you'll have to
bring it into the arm repo and enable it to be built. I don't think
I've tested a 32-bit build on rpi3 since we split the trees. Can you
also sent me your compiler commands when you build the 5.4.93 kernel?
Thanks
Greg
I'm trying to compile it now for arm64. But we don't have default
configs in arm64/ folder (like multi_v7)
Command I used for 5.4.93 are (toolchain bin/ added to PATH):
../linux-patched $ export ARCH=arm
../linux-patched $ export CROSS_COMPILE=arm-none-linux-gnueabihf-
../linux-patched $ make multi_v7_defconfig
../linux-patched $ make zImage modules dtbs -j12
