[OS-BUILD PATCHv2 0/3] Add clang config framework
by Don Zickus (via Email Bridge) 29 Sep '23

29 Sep '23

From: Don Zickus on gitlab.com Merge Request: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/2654 Compiling for clang is getting trickier to do because the configs are different than gcc in some cases. Mimic the kgcov framework to setup clang to be easier to update their configs. This framework is designed to blindly merge.py with any configs fed to it. This is unlike the build_configs framework where it uses priority.rhel|fedora rules to merge things. This leads to strange cases where clang debug configs need different settings than clang non-debug configs. For non-lto clang, due to clang bugs it is easy to disable the debug features and get away with this. But once resolved we will have to reinvestigate. For lto clang, I just hack out the debug and kgcov config files due to clashing Kconfig depend rules. I don't expect this to be a long term solution. Perhaps when our config rework is fully realized this just melts away. TBD.

[OS-BUILD PATCH] fedora: Switch TI_SCI_CLK and TI_SCI_PM_DOMAINS symbols to built-in
by Javier Martinez Canillas (via Email Bridge) 29 Sep '23

From: Javier Martinez Canillas <javierm(a)redhat.com> fedora: Switch TI_SCI_CLK and TI_SCI_PM_DOMAINS symbols to built-in These two are currently built as a module, but this prevents the K3 AM6xx boards to boot. For example, an AM625 BeaglePlay hangs on boot after this: ## Flattened Device Tree blob at ffb0e8e0 Booting using the fdt blob at 0xffb0e8e0 Working FDT set to ffb0e8e0 Loading Ramdisk to 8bcb0000, end 8ffff195 ...

[OS-BUILD PATCHv3 0/3] redhat/Makefile.cross: Disable subpackages
by Prarit Bhargava (via Email Bridge) 23 Sep '23

23 Sep '23

From: Prarit Bhargava on gitlab.com Merge Request: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/2723 There are subpackages that won't compile due to architectural differences and cross compiling packaging issues. Disable these packages from cross compiling. This shouldn't be a shock as CKI is not building these in cross compiles either.
