QUESTION
I would like to share a test question I met recently and discuss about it:
Write a C program that roughly measures the overhead of a context switch >between the kernel and userspace on a UNIX/Linux system (without using the >pthread API). Please indicate the assumptions your rough estimation is based >on.
I would like to discuss with more advanced C programmers the different options of this problematic.
I have limited knowledge in C programming and I documented myself to provide an acceptable answer:
https://www.researchgate.net/post/How_can_I_measure_thread_creation_and_destruction
https://github.com/eliben/code-for-blog/blob/master/2018/threadoverhead/thread-pipe-msgpersec.c
I realized quickly, despite of my limited knowledge, the ambiguity of the question. Indeed, the question doesn't stipulate if an answer should be given in unit of time or memory.
I personally chose to develop my reasoning measuring time with the library time.h and a very simple snippet. Result should be divided by 1 000 000.
Does my answer make sense or am I completely missing the point ?
...ANSWER
Answered 2019-Feb-27 at 10:52Amazingly enough, the answer I provided above was accepted as correct in this test.
However to optimize the accuracy, we should rule out the "printf" method and go for either a syscall with invalid parameter as mentioned by Alex Hoppus or an empty method.
At the end, result should divided by 2 as mentioned by Alex Hoppus.
QUESTION
I am trying to make this code work : https://github.com/eliben/code-for-blog/blob/master/2011/dwarf_get_func_addr.c It is extracted from a tutorial made by Eli Bendersky on http://eli.thegreenplace.net/2011/02/07/how-debuggers-work-part-3-debugging-information Unfortunately, low pc and high pc return always the same address for almost every function:
...ANSWER
Answered 2017-Sep-13 at 02:35The code in dwarf_get_func_addr.c
has at least one bug: it assumes that every function has DW_AT_low_pc
and DW_AT_high_pc
attributes, and will print uninitialized values if that is not the case.
You should initialize lowpc = highpc = -1;
on line 42, so as not to print unintialized values.
Other than that, it's impossible to help you without access to your lulesh_normal
binary.
You should do readelf -wi lulesh_normal
, and then step through list_func_in_die
in a debugger, and compare what the program is reading there with the output from readelf
-- they should match one to one. If they don't, your version of libdwarf
is possibly buggy.
