kern build problem

[jxq96]

Althoght my platform meets the requriements of dune(all yes when run dune_req.sh). But I cannot build the dune, actuall failed when build kern. My OS is Ubuntu16.04, kernel version 4.15.0-142. From the compiler error: implicit declaration of function ‘x2apic_wrmsr_fence’, I think the problem is the kernel version. So which kernel should I use
?

I met the same problem. I think we should go back to version 3.0+, Unless we modify the code to be compatible with the new kernel. :(

Yes, you have to either go back to older version linux or modify dune source code.

Some header files are no longer provided in linux.

I saw that you forked a repo called Loongson Dune, does it work?

Yes, though may not be perfect, but it does.

In fact, loongson-dune is something my lab classmate is working on. And my project is built upon it.

I'm also trying to build Dune in a recent kernels and I found some issues.
For starters the compiler can't find a header named asm/ipi.h.

After looking into the loongson-dune repository I think they do not support x86, at
least when I try to compile it prints:
loongarch/arch.c: In function ‘arch_dump_regs’:
loongarch/arch.c:22:27: error: ‘struct kvm_regs’ has no member named ‘gpr’
22 | (unsigned long long)regs.gpr[0],

In fact I need this DAX feature:
https://www.kernel.org/doc/Documentation/filesystems/dax.txt
which I think is only available in recent kernels.
Is there any chance Dune can be supported in more recent kernels?
