Hi
I use crash8.0.4_arm64 to parse the ramdump of android15-k6.6, load the symbol of ko,
and disassemble the functions in ko through the "dis -lx" command.
I can get the assembly instructions, but I cannot get the corresponding assembly
instructions. lines of source code.
The following error is reported when using the command
GNU_RESOLVE_TEXT_ADDR: returned via gdb_error_hook (1 buffer in use)
GNU_GET_FUNCTION_RANGE: returned via gdb_error_hook (1 buffer in use
hmm, I've not seen this kind of errors with the "dis -l".
It looks like the former cannot find the function or it's not a function:
case GNU_RESOLVE_TEXT_ADDR:
sym = find_pc_function(req->addr);
if (!sym || TYPE_CODE(sym->type) != TYPE_CODE_FUNC)
req->flags |= GNU_COMMAND_FAILED;
break;
what do you see with these after loading the module?
crash> sym <function name>
crash> whatis <function name>
crash> gdb info line <function name>
Thanks,
