I'm asking because we'd need to make sure that Github version of libbpf Makefile and include directory has all the necessary pieces as well (so I'd appreciate if you could take a look at that as well, if you haven't already). > > base-commit: db5ca265e3334b48c4e3fa07eef79e8bc578c430 > -- > 2.43.0 >

Ah, apologies for not stating that explicitly. It's tools/arch/riscv/include/asm/{barrier.h,fence.h} Cheers, Björn

RISC-V libbpf/perf needs this fix in 6.12 to properly build. Would it be possible to have it in the bpf tree, and have it land in 6.12-rc7? Andreas that has a similar fix [1].

Hi Bjorn, Yes, libbpf and selftests fixes are generally applied through bpf-next, unless the issue is pretty bad and immediate. I'm sorry, but unfortunately it's too late now to move those patches as it's now been more than a month since they landed. For the future, please let us know ASAP if you think patches were misrouted. I think we are stuck with the need to do a stable backport for these, sorry. > > RISC-V libbpf/perf needs this fix in 6.12 to properly build.

Thanks for getting back, and noted for the future. Cheers, Björn
