CI build failure in v6.6-rt

CI build failure in v6.6-rt

[Clark Williams]

Greg,

Kernel CI is reporting a build failure on v6.6-rt:

https://grafana.kernelci.org/d/build/build?orgId=1&var-datasource=default&var-build_architecture=riscv&var-build_config_name=defconfig&var-id=maestro:66a6b448bb1dfd36a925ebef

It's in arch/riscv/kernel/cpufeature.c where a return statement in
check_unaligned_access() doesn't have a value (and
check_unaligned_access returns int).

Is 6.6 stable supporting RiscV? If so then we either have to fix that
return, or backport the refactor of arch/riscv/kernel/cpufeature.c
(f413aae96cda0).  If it's not then who should I talk to about turning
off riscv CI builds for v6.6-rt?

Thanks,
Clark

Why not ask the people responsible for the -rt patchset?  If this isn't
an issue on a non-rt kernel, then I think you found the problem :)

thanks,

I'm sorry. I misunderstood Clark and assumed this is a stable issue. Now
that I have the needed pointers, it is a RT-stable issue only.
I'm going to drop the stable folks from Cc: and reply with a patch.
