How to view and change kernel memory size?

Question

How can i view the kernel's share of memory on a machine? How can I increase it? What should I consider before doing it?

Your question makes no sense: the kernel takes whatever memory it needs, no more, no less. Is there a specific feature you're trying to tune? (There are settings you can tune, but the defaults are right in >99.99% of use cases.)

Memory for what?

You can adjust kernel parameters in /etc/sysctl.conf

try running

sysctl -a | egrep -i "(vm|page|mem|shm)"

for some example kernel memory-related parameters
