Re: [Crash-utility] Identifying structures related to memory , semaphores using crash utility

Hi Rachita, I am referring to the second column of sym -l command output. From sym -l command we get the information about symbol types.As you have specified the same information is present in system.map file as well. Since the output of command " nm <vmlinux file>" is placed in system.map file, I checked the man page of "nm" and got to know the symbol types. I came to know that types t,T (present in the second column of sym -l command) represent symbols that are located in text segment. Explanation about other data types are also given. I wanted to know whether only functions can reside in text segment or any other variables reside as well. If only functions reside in Text segment, it would be easy to identify the symbols that are functions. And I can easily segregate them from other symbols. So I thought this may help us to identify whether a given symbol name is function or not. I hope you can provide a better insight to this. As you and Dave had suggested I tried using gdb info command. But it is consuming lot of time. Including that in my script would slow down the entire code. It doesn't suit my need either. If you know any other method (need not be crash utility) to identify the symbol definitions, please let me know.

This is the same information one can get from the System.map file. Probably one way could be to query 'gdb' for each of these symbols for their symbol type, as Dave had mentioned.
