Is it impossible to build kvmtool

[pashaniaosi]

hello, when I follow the Step5("KVM RISCV64 on QEMU") to build kvmtool, there are something wrong:

Makefile:363: Skipping optional libraries: bfd zlib aio
  CC       builtin-balloon.static.o
In file included from include/linux/rbtree.h:32,
                 from include/kvm/devices.h:4,
                 from include/kvm/pci.h:10,
                 from include/kvm/vfio.h:6,
                 from include/kvm/kvm-config.h:5,
                 from include/kvm/kvm.h:6,
                 from builtin-balloon.c:9:
include/linux/kernel.h:5:10: fatal error: asm/kernel.h: No such file or directory
    5 | #include "asm/kernel.h"
      |          ^~~~~~~~~~~~~~
compilation terminated.
make: *** [Makefile:477: builtin-balloon.static.o] Error 1

so, I list all the files in riscv/include/asm:

kvm.h

the file kernel.h is not found in the directory(riscv/include/asm), but it can be found in other directories(mips/include/asm, x86/include/asm). So, I doubt the git repository of kvmtool lost the header file kernel.h of riscv.

I try to fix the error by deleting this line (#include "asm/kernel.h"). It really works, but whether would affect the result of make?

Please export "ARCH=riscv" and "CROSS_COMPILE" environment variable before building.

Please export "ARCH=riscv" and "CROSS_COMPILE" environment variable before building.

I have done this before building. According to the error message, it lost a header file "kernel.h" in the directory (riscv/include/asm) and I can't find this file in the kvmtool repository.

KVMTOOL only includes UAPI headers exported from the kernel.

The newest commit had fixed this issue.

The official repository had added missing asm/kernel.h header.
