Dear all,
I want to get the address of each memory access. Meanwhile, I also
want to know which thread the memory access belongs to.
Now I found that we can figure out the thread id by reading from
memory address %fs+0x10. However, there might be page fault if I try to
read from this address.
I think I only need to record the thread id when there is a
context switch, in which case, the thread id information must be in the
memory.
However I don't know how to detect the thread context switch in ptlsim.
Any ideas? Thanks a lot!!!!!
-Regards
Shen Zhong
