kernel symbols or valibles

yatin — Mon, 15 Mar 2004 23:44:33 GMT

where can i get a list of all kernel symbols(variables) and their description(like what is their use or what they mean). Following command gives me variables and their values
echo '$e' | adb64 -k /stand/vmunix /dev/mem

Have a look at /var/sam/boot.config

or

Yatin,

your adb command dumps all external symbols from the kernel file. More than 6000 on my system, so don't expect to find any documentation on 99.9% of them unless you have source code access. :)

If you need information about kernel tunables then the man pages of 11.23 are a valuable information resource. They are also on the web... check section 5 of:

http://docs.hp.com/hpux/onlinedocs/B2355-60103/B2355-60103.html

Best regards...
Dietmar.

I like to add a little more info.

tunable parms are C #defines. These values are then substuted into the kernal code for compiling.
On my 11i system the parms are in /stand/build/tune.h

It shows the kernal parms and the values.
(You can use sam as stated above. It is interesting to see the contents of the actual file.)
