[gentoo-amd64] Kernel Config for /proc/self/smaps

[gentoo-amd64] Kernel Config for /proc/self/smaps

[P.V.Anthony]

Hi,

I need help to get /proc/self/smaps.

Is there a setting that need to be activated in the kernel?

Currently under the kernel config, filesystems/pseudo/proc is activated. 
Any other setting to activated?

Yes.  One you enable proc, three sub-menu items should pop into 
existence.  Read the help for each.  That should give you your answer.
=:^)

(It's Enable /proc page monitoring, FWIW.)

Thank you very much for replying.

Currently configuring kernel version 2.6.26 using "make menuconfig".

Went to "filesystems" and then to "pseudo filesystems". The "proc" has 
already been activated. On this system, I cannot even de-activate the 
"proc". I did that for testing.

Under "proc" there is "/proc/kcore support". That is also activated.

Tried reading the help for the /proc/kcore but nothing there.

I can manually set "CONFIG_PROC_PAGE_MONITOR=y" in the ".config" file.

I would really like to learn how to set this using "make menuconfig". 
Please bear with me and guide me on how to set 
"CONFIG_PROC_PAGE_MONITOR=y" using "make menuconfig".

[I've been offline for a week due to using bad memory while trying to 
flash a BIOS.  Naturally it crashed, and I couldn't boot my main 
machine.  I ended up ordering a pre-flashed BIOS chip from two states a 
way... and waiting the few days for it to ship.  I feel like I'm just 
back from the dead! =:^)  ]

Hmm... perhaps it's elsewhere in the 2.6.26 kernel config.  I'm now 
running 2.6.31, and will be starting on the 2.6.32 rcs in a week or two...

It's also possible it's turned off and not even available to you due to 
some other dependency.  I'd try tracing it if I hadn't just fallen a week 
behind, just to see.  You can grep "PROC__PAGE_MONITOR" in the kernel 
sources and see what comes up if you want.  That's what I'd do, tho 
having done stuff like that before I might be better equipped to filter 
out the uninteresting entries.  But you gotta start somewhere. =:^)

In menuconfig / is a shortcut to a find utility into which entering
config_proc_page_monitor takes one to a help page with the following
info:

Symbol: PROC_PAGE_MONITOR [=y]
Prompt: Enable /proc page monitoring 
   Defined at fs/proc/Kconfig:61 
   Depends on: PROC_FS && MMU && EMBEDDED 
   Location: 
     -> File systems> 
       -> Pseudo filesystems> 
         -> /proc file system support (PROC_FS [=y]
