I don't see exactly how the previous build bugs were addressed, but I can confirm that this version builds. Regarding the two irqchip patches, 621e7015b529 ("irqchip/loongson-liointc: Fix build error for LoongArch") is a good way to work around the mips oddity, and I have no problem taking that through the asm-generic tree. The other one, f54b4a166023 ("irqchip: Adjust Kconfig for Loongson"), looks mostly unnecessary, and I think only the LOONGSON_HTPIC change should be included here, while I would leave out the COMPILE_TEST changes and instead have the driver changes take care of making it possible to keep building it on x86, possibly doing depends on MACH_LOONGSON64 || (COMPILE_TEST && ACPI) in the future, after the loongarch64 ACPI support is merged. > After some small tweaks: > > - adding "#include " to arch/loongarch/include/asm/ptrace.h, > - adding an arch/loongarch/include/uapi/asm/bpf_perf_event.h with the > same content as arch/arm64's, and > - adding "depends on ARM64 || X86" to > drivers/platform/surface/aggregator/Kconfig, > > the current loongarch-next HEAD (commit > 36552a24f70d21b7d63d9ef490561dbdc13798d7) now passes allmodconfig build > (with CONFIG_WERROR disabled; my Gentoo-flavored gcc-12 seems to emit > warnings on a few drivers). The only one of these issues that I see is the surface aggregator one. I think we can address all three as follow-up fixes after -rc1 if the port gets merged and these are still required. > The majority of userspace ABI has been stable for a few months already, > after the addition of orig_a0 and removal of newfstatat; the necessary > changes to switch to statx are already reviewed [2] / merged [3], and > have been integrated into the LoongArch port of Gentoo for a while.
