ipipe kernel image compile error

ipipe kernel image compile error

[C Smith]

Hi,

I'm having a problem compiling Kernel 4.19.109 with
ipipe-core-4.19.109-cip22-x86-11.patch using Xenomai-3.1.

$ scripts/prepare-kernel.sh --linux=../linux/
--ipipe=../ipipe-core-4.19.109-cip22-x86-11.patch --arch=x86

I'm compiling with:
$ m -j4 bzImage

I'm getting following error:

arch/x86/kernel/apb_timer.c: In function ‘apbt_set_mapping’:
arch/x86/kernel/apb_timer.c:122:21: error: too few arguments to function
‘dw_apb_clocksource_init’
  clocksource_apbt = dw_apb_clocksource_init(APBT_CLOCKSOURCE_RATING,
                     ^~~~~~~~~~~~~~~~~~~~~~~

Hi,

i do not know what that timer is or whether it is wise to choose it for
an ipipe kernel.

You can probably work around the issue by not setting CONFIG_APB_TIMER
in your kernel configuration. And my guess is that you will not be
missing any features. In order to reproduce the issue, your config
would be useful.

I thought we came across this already and fixed it but... no:

https://gitlab.denx.de/Xenomai/ipipe-noarch/-/commit/a1cfa77db06c3967fc8c790eefa656562f0fba5d
is broken as it is not arch-agnostic. I'll rip that off from the x86
tree for the next release.

Meanwhile, you can work around that by disabling CONFIG_X86_INTEL_MID -
unless you are on an Intel MID platform. Are you?
