From what I can tell, I think this patch ("printk: use the lockless ringbuffer") breaks lx-dmesg in CONFIG_GDB_SCRIPTS.
(gdb) lx-dmesg Python Exception <class 'gdb.error'> No symbol "log_first_idx" in specified context.: Error occurred in Python: No symbol "log_first_idx" in specified context.
This command is used to dump the printk log buffer.
It looks like the only places left in the kernel that reference are:
- Documentation/admin-guide/kdump/gdbmacros.txt - Documentation/admin-guide/kdump/vmcoreinfo.rst - scripts/gdb/linux/dmesg.py
I believe this commit removed log_first_idx, so all of the above probably need to be fixed up, too.
