Hello,
I know this list has been rather quiet for a while... so I might as
well ask a question :-)
I really thought that this list is completely dead :-)
This does not seem to be the case, however, when I do a listing in
/proc/kcore on my machine (F8) which has 2 GB of memory:
ls -lh /proc/kcore
-r-------- 1 root root 897M 2008-08-01 19:05 /proc/kcore
I have confirmed the same type of results on other machines to which I
have access. I also do not seem to have the kcore.h file on my system
(and I have kernel-devel installed), since it is a zero byte file:
-rw-r--r-- 1 root root 0 2008-07-21 02:05
/usr/src/kernels/2.6.25.11-60.fc8-i686/include/config/proc/kcore.h
As far as I know, the size of kcore is equal not to the size of _all_ physical memory installed on the machine, but just to the amount of memory accessible by kernel.
Your kernel seems to be compiled with HIGHMEM support, and if you do `ls -l /proc/kcore` you see your LOWMEM size, the real memory that the kernel uses. That the reason why the difference you mentioned comes.
Someone will correct me, if I'm wrong :)
