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-0.patch
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
--verbose
Preparing kernel 5.4.94 in

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
