Subject: scripts/gdb: fix usage of MOD_TEXT not defined when CONFIG_MODULES=n
Date: Tue, 31 Oct 2023 13:49:04 +0000
MOD_TEXT is only defined if CONFIG_MODULES=y which lead to loading failure
of the gdb scripts when kernel is built without CONFIG_MODULES=y:
Reading symbols from vmlinux...
Traceback (most recent call last):
File "/foo/vmlinux-gdb.py", line 25, in <module>
import linux.constants
File "/foo/scripts/gdb/linux/constants.py", line 14, in <module>
LX_MOD_TEXT = gdb.parse_and_eval("MOD_TEXT")
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
gdb.error: No symbol "MOD_TEXT" in current context.
Add a conditional check on CONFIG_MODULES to fix this error.
