kbuild-next: .tmp vmlinux syms files

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I am playing with Sami's gendwarfksyms v6 which is based on kbuild-next.

Noticed:

$ LC_ALL=C ls -alth .tmp_vmlinux*

-rw-rw-r-- 1 dileks dileks 3.1M Nov 22 20:52 .tmp_vmlinux2.kallsyms.o
-rw-rw-r-- 1 dileks dileks  34M Nov 22 20:52 .tmp_vmlinux2.kallsyms.S
-rw-rw-r-- 1 dileks dileks 6.5M Nov 22 20:52 .tmp_vmlinux2.syms
-rwxrwxr-x 1 dileks dileks 101M Nov 22 20:52 .tmp_vmlinux2

-rw-rw-r-- 1 dileks dileks 3.1M Nov 22 20:52 .tmp_vmlinux1.kallsyms.o
-rw-rw-r-- 1 dileks dileks  34M Nov 22 20:52 .tmp_vmlinux1.kallsyms.S
-rw-rw-r-- 1 dileks dileks 6.5M Nov 22 20:52 .tmp_vmlinux1.syms
-rwxrwxr-x 1 dileks dileks  52M Nov 22 20:52 .tmp_vmlinux1.btf.o
-rwxrwxr-x 1 dileks dileks 514M Nov 22 20:52 .tmp_vmlinux1

-rw-rw-r-- 1 dileks dileks 2.1K Nov 22 20:51 .tmp_vmlinux0.kallsyms.o
-rw-rw-r-- 1 dileks dileks 6.3K Nov 22 20:51 .tmp_vmlinux0.kallsyms.S
-rw-rw-r-- 1 dileks dileks    0 Nov 22 20:51 .tmp_vmlinux.kallsyms0.syms

.tmp_vmlinux.kallsyms0.syms is NULL byte.

And looking at the other .tmp vmlinux syms files:

.tmp_vmlinux2.syms
.tmp_vmlinux1.syms
.tmp_vmlinux.kallsyms0.syms

Should this be from the naming of files?

.tmp_vmlinux.kallsyms0.syms -> .tmp_vmlinux0.syms

My build-script and kernel-config are attached.

If you need further information, please let me know.

Best thanks and regards,
