Subject: scripts/gdb: support !CONFIG_MODULES gracefully
If CONFIG_MODULES is not enabled, lx-lsmod tries to find
a non-existent symbol and generates an unfriendly traceback:
(gdb) lx-lsmod
Address Module Size Used by
Traceback (most recent call last):
File "scripts/gdb/linux/modules.py", line 75, in invoke
for module in module_list():
File "scripts/gdb/linux/modules.py", line 24, in module_list
module_ptr_type = module_type.get_type().pointer()
File "scripts/gdb/linux/utils.py", line 28, in get_type
self._type = gdb.lookup_type(self._name)
gdb.error: No struct type named module.
Error occurred in Python command: No struct type named module.
Catch the error and return an empty module_list() for a clean command
output as follows:
