scripts/gdb: change kernel config dumping method

2022-06-11T09:31:53+00:00

MAGIC_START("IKCFG_ST") and MAGIC_END("IKCFG_ED") are moved out from the kernel_config_data variable. Thus, we parse kernel_config_data directly instead of considering offset of MAGIC_START and MAGIC_END.

scripts/gdb: add kernel config dumping command

2019-05-15T02:52:51+00:00

lx-configdump dumps the contents of the gzipped .config to a text file when the config is included in the kernel with CONFIG_IKCONFIG. By default, the file written is called config.txt, but it can be any user supplied filename as well. If the kernel config is in a module (configs.ko), then it can be loaded along with symbols for the module loaded with 'lx-symbols' and then this command will still work. Obviously if you have the whole vmlinux then this can also be achieved with scripts/extract-ikconfig, but this gdb script can be useful to confirm that the memory contents of the config in memory and the vmlinux contents on disk match what is expected.
