This is used to force the Linux VM to keep a minimum number, of kilobytes free.
|
||
|
|
The VM uses this number to compute a watermark[WMARK_MIN] value for each lowmem
|
||
|
|
zone in the system. Each lowmem zone gets a number of reserved free pages based
|
||
|
|
proportionally on its size.
|
||
|
|
|
||
|
|
Some minimal amount of memory is needed to satisfy PF_MEMALLOC allocations;
|
||
|
|
if you set this to lower than 1024KB, your system will become subtly broken,
|
||
|
|
and prone to deadlock under high loads.
|
||
|
|
|
||
|
|
Setting this too high will OOM your machine instantly.

config VM_OVERCOMMIT_GUESS

help
|

|
|
This value contains a flag that enables memory overcommitment.
|
||
|
|
|
||
|
|
When this flag is 0, the kernel attempts to estimate the amount of free memory
|
||
|
|
left when userspace requests more memory.
|
||
|
|
|
||
|
|
When this flag is 1, the kernel pretends there is always enough memory until
|
||
|
|
it actually runs out.
|
||
|
|
|
||
|
|
When this flag is 2, the kernel uses a "never overcommit" policy that attempts
|
||
|
|
to prevent any overcommit of memory.
|
||
|
|
This feature can be very useful because there are a lot of programs that malloc()
|
||
|
|
huge amounts of memory "just-in-case" and don't use much of it.
|
||
|
|
|
||
|
|
See Documentation/vm/overcommit-accounting and security/commoncap.c::cap_vm_enough_memory()

|
