Bug#505571: pmap -x doesn't return any useful information
Hi, > Hmm. Must of been a "future feature" thing. indeed! Incidentally, I've just figured out that the RSS can be found in /proc//smaps. Thanks for looking into it so quickly.

With any kernel!! I had a look at the code:
if(x_option){
[...]
? "%016"KLF"x %7lu - - - %s %s\n"
[...]
if(!x_option && !d_option){
[...]
? "%016"KLF"x %6luK %s %s\n"
Hmm. Must of been a "future feature" thing.

For instance, I compiled the following test program: I don't personally use this program much myself but I can confirm that I have the same results for my 2.6.26 kernel. My initial impression is that it is a problem with the scanf in pmap.c, we don't check for a return value there :( so if it doesn't match then we will never know something is wrong. Perhaps /proc//maps has had a slight format change. At least its a real easy one to check if it is working or not, I've not found anything that pmap -x works ok with. - Craig -- Craig Small GnuPG:1C1B D893 1418 2AF4 45EE 95CB C76C E5AC 12CA DFA5 http://www.enc.com.au/ csmall at : enc.com.au http://www.debian.org/ Debian GNU/Linux, software should be Free -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Bug#505571: pmap -x doesn't return any useful information
Package: procps
Version: 1:3.2.7-3
Severity: normal
With a standard Etch kernel (linux-image-2.6.18-6-686 2.6.18.dfsg.1-21),
I am unable to get 'pmap -x ' to show any information that 'pmap
' doesn't show. For instance, I compiled the following test program:
#include
int main () {
void *foo;
foo = malloc(20*1024*1024);
sleep(30);
free(foo);
return 0;
}
and then ran 'pmap -x 9672' on it:
9672: ./test

I was hoping to see that the memory allocated at b6a06000 has a
reassuringly low RSS, but all I ever see is "-" (same on RHEL4 with
2.6.9 kernel and RHEL5 with 2.6.18 kernel, by the way).
I would really appreciate it if this parameter worked, because I haven't
found any other way to get the information I'm looking for.
Regards,
Michael
