2.4 /proc/sys/vm - The virtual memory subsystem
|
||||
-----------------------------------------------
|
||||
|
||||
The files in this directory can be used to tune the operation of the virtual
|
||||
memory (VM) subsystem of the Linux kernel.
|
||||
|
||||
vfs_cache_pressure
|
||||
------------------
|
||||
|
||||
Controls the tendency of the kernel to reclaim the memory which is used for
|
||||
caching of directory and inode objects.
|
||||
|
||||
At the default value of vfs_cache_pressure=100 the kernel will attempt to
|
||||
reclaim dentries and inodes at a "fair" rate with respect to pagecache and
|
||||
swapcache reclaim. Decreasing vfs_cache_pressure causes the kernel to prefer
|
||||
to retain dentry and inode caches. Increasing vfs_cache_pressure beyond 100
|
||||
causes the kernel to prefer to reclaim dentries and inodes.

dirty_background_bytes

-------------------------
|

|
||||
The pdflush writeback daemons will periodically wake up and write `old' data
|

out to disk. This tunable expresses the interval between those wakeups, in
|

100'ths of a second.
|

||||
Setting this to zero disables periodic writeback altogether.
|
||||
|
||||
dirty_expire_centisecs
|
||||
----------------------
|
||||
|
||||
This tunable is used to define when dirty data is old enough to be eligible
|
||||
for writeout by the pdflush daemons. It is expressed in 100'ths of a second.
|
||||
Data which has been dirty in-memory for longer than this interval will be
|
||||
written out next time a pdflush daemon wakes up.

highmem_is_dirtyable
|
||||
--------------------
|
||||
|
||||
Only present if CONFIG_HIGHMEM is set.
|
||||
|
||||
This defaults to 0 (false), meaning that the ratios set above are calculated
|
||||
as a percentage of lowmem only. This protects against excessive scanning
|
||||
in page reclaim, swapping and general VM distress.
|
||||
|
||||
Setting this to 1 can be useful on 32 bit machines where you want to make
|
||||
random changes within an MMAPed file that is larger than your available
|
||||
lowmem without causing large quantities of random IO. Is is safe if the
|
||||
behavior of all programs running on the machine is known and memory will
|
||||
not be otherwise stressed.
|
||||
|
||||
legacy_va_layout
|
||||
----------------
|
||||
|
||||
If non-zero, this sysctl disables the new 32-bit mmap mmap layout - the kernel
|
||||
will use the legacy (2.4) layout for all processes.
|
||||
|
||||
lowmem_reserve_ratio
|
||||
---------------------
|
||||
|
||||
For some specialised workloads on highmem machines it is dangerous for
|
||||
the kernel to allow process memory to be allocated from the "lowmem"
|
||||
zone. This is because that memory could then be pinned via the mlock()
|
||||
system call, or by unavailability of swapspace.
|
||||
|
||||
And on large highmem machines this lack of reclaimable lowmem memory
|
||||
can be fatal.
|
||||
|
||||
So the Linux page allocator has a mechanism which prevents allocations
|
||||
which _could_ use highmem from using too much lowmem. This means that
|
||||
a certain amount of lowmem is defended from the possibility of being
|
||||
captured into pinned user memory.
|
||||
|
||||
(The same argument applies to the old 16 megabyte ISA DMA region. This
|
||||
mechanism will also defend that region from allocations which could use
|
||||
highmem or lowmem).
|
||||
|
||||
The `lowmem_reserve_ratio' tunable determines how aggressive the kernel is
|
||||
in defending these lower zones.
|
||||
|
||||
If you have a machine which uses highmem or ISA DMA and your
|
||||
applications are using mlock(), or if you are running with no swap then
|
||||
you probably should change the lowmem_reserve_ratio setting.
|
||||
|
||||
The lowmem_reserve_ratio is an array. You can see them by reading this file.

||||

||||

-
|
||||
Note: # of this elements is one fewer than number of zones. Because the highest
|
||||
zone's value is not necessary for following calculation.
|
||||
|
||||
But, these values are not used directly. The kernel calculates # of protection
|
||||
pages for each zones from them. These are shown as array of protection pages
|
||||
in /proc/zoneinfo like followings. (This is an example of x86-64 box).
|
||||
Each zone has an array of protection pages like this.

|
||||
These protections are added to score to judge whether this zone should be used
|
||||
for page allocation or should be reclaimed.
|
||||
|
||||
In this example, if normal pages (index=2) are required to this DMA zone and
|
||||
pages_high is used for watermark, the kernel judges this zone should not be
|
||||
used because pages_free(1355) is smaller than watermark + protection[2]
|
||||
(4 + 2004 = 2008). If this protection value is 0, this zone would be used for
|
||||
normal page requirement. If requirement is DMA zone(index=0), protection[0]
|
||||
(=0) is used.
|
||||
|
||||
zone[i]'s protection[j] is calculated by following expression.
|
||||
|
||||
(i < j):
|
||||
zone[i]->protection[j]
|
||||
= (total sums of present_pages from zone[i+1] to zone[j] on the node)
|
||||
/ lowmem_reserve_ratio[i];
|
||||
(i = j):
|
||||
(should not be protected. = 0;
|
||||
(i > j):
|
||||
(not necessary, but looks 0)
|
||||
|
||||
The default values of lowmem_reserve_ratio[i] are
|
||||
256 (if zone[i] means DMA or DMA32 zone)
|
||||
32 (others).
|
||||
As above expression, they are reciprocal number of ratio.
|
||||
256 means 1/256. # of protection pages becomes about "0.39%" of total present
|
||||
pages of higher zones on the node.
|
||||
|
||||
If you would like to protect more pages, smaller values are effective.
|
||||
The minimum value is 1 (1/1 -> 100%).
|
||||
|
||||
page-cluster
|
||||
------------
|
||||
|
||||
page-cluster controls the number of pages which are written to swap in
|
||||
a single attempt. The swap I/O size.
|
||||
|
||||
It is a logarithmic value - setting it to zero means "1 page", setting
|
||||
it to 1 means "2 pages", setting it to 2 means "4 pages", etc.
|
||||
|
||||
The default value is three (eight pages at a time). There may be some
|
||||
small benefits in tuning this to a different value if your workload is
|
||||
swap-intensive.
|
||||
|
||||
overcommit_memory
|
||||
-----------------
|
||||
|
||||
Controls overcommit of system memory, possibly allowing processes
|
||||
to allocate (but not use) more memory than is actually available.
|
||||
|
||||
|
||||
0 - Heuristic overcommit handling. Obvious overcommits of
|
||||
address space are refused. Used for a typical system. It
|
||||
ensures a seriously wild allocation fails while allowing
|
||||
overcommit to reduce swap usage. root is allowed to
|
||||
allocate slightly more memory in this mode. This is the
|
||||
default.
|
||||
|
||||
1 - Always overcommit. Appropriate for some scientific
|
||||
applications.
|
||||
|
||||
2 - Don't overcommit. The total address space commit
|
||||
for the system is not permitted to exceed swap plus a
|
||||
configurable percentage (default is 50) of physical RAM.
|
||||
Depending on the percentage you use, in most situations
|
||||
this means a process will not be killed while attempting
|
||||
to use already-allocated memory but will receive errors
|
||||
on memory allocation as appropriate.
|
||||
|
||||
overcommit_ratio
|
||||
----------------
|
||||
|
||||
Percentage of physical memory size to include in overcommit calculations
|
||||
(see above.)
|
||||
|
||||
Memory allocation limit = swapspace + physmem * (overcommit_ratio / 100)
|
||||
|
||||
swapspace = total size of all swap areas
|
||||
physmem = size of physical memory in system
|
||||
|
||||
nr_hugepages and hugetlb_shm_group
|
||||
----------------------------------
|
||||
|
||||
nr_hugepages configures number of hugetlb page reserved for the system.
|
||||
|
||||
hugetlb_shm_group contains group id that is allowed to create SysV shared
|
||||
memory segment using hugetlb page.
|
||||
|
||||
hugepages_treat_as_movable
|
||||
--------------------------
|
||||
|
||||
This parameter is only useful when kernelcore= is specified at boot time to
|
||||
create ZONE_MOVABLE for pages that may be reclaimed or migrated. Huge pages
|
||||
are not movable so are not normally allocated from ZONE_MOVABLE. A non-zero
|
||||
value written to hugepages_treat_as_movable allows huge pages to be allocated
|
||||
from ZONE_MOVABLE.
|
||||
|
||||
Once enabled, the ZONE_MOVABLE is treated as an area of memory the huge
|
||||
pages pool can easily grow or shrink within. Assuming that applications are
|
||||
not running that mlock() a lot of memory, it is likely the huge pages pool
|
||||
can grow to the size of ZONE_MOVABLE by repeatedly entering the desired value
|
||||
into nr_hugepages and triggering page reclaim.
|
||||
|
||||
laptop_mode
|
||||
-----------
|
||||
|
||||
laptop_mode is a knob that controls "laptop mode". All the things that are
|
||||
controlled by this knob are discussed in Documentation/laptops/laptop-mode.txt.
|
||||
|
||||
block_dump
|
||||
----------
|
||||
|
||||
block_dump enables block I/O debugging when set to a nonzero value. More
|
||||
information on block I/O debugging is in Documentation/laptops/laptop-mode.txt.
|
||||
|
||||
swap_token_timeout
|
||||
------------------
|
||||
|
||||
This file contains valid hold time of swap out protection token. The Linux
|
||||
VM has token based thrashing control mechanism and uses the token to prevent
|
||||
unnecessary page faults in thrashing situation. The unit of the value is
|
||||
second. The value would be useful to tune thrashing behavior.
|
||||
|
||||
drop_caches
|
||||
-----------
|
||||
|
||||
Writing to this will cause the kernel to drop clean caches, dentries and
|
||||
inodes from memory, causing that memory to become free.
|
||||
|
||||
To free pagecache:
|
||||
echo 1 > /proc/sys/vm/drop_caches
|
||||
To free dentries and inodes:
|
||||
echo 2 > /proc/sys/vm/drop_caches
|
||||
To free pagecache, dentries and inodes:
|
||||
echo 3 > /proc/sys/vm/drop_caches
|
||||
|
||||

|
||||
user should run `sync' first.

* What is the magic SysRq key?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
@@ -211,6 +210,24 @@ within a function called by handle_sysrq, you must be aware that you are in
|
||||
a lock (you are also in an interrupt handler, which means don't sleep!), so
|
||||
you must call __handle_sysrq_nolock instead.
|
||||
|
||||
* When I hit a SysRq key combination only the header appears on the console?
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
Sysrq output is subject to the same console loglevel control as all
|
||||
other console output. This means that if the kernel was booted 'quiet'
|
||||
as is common on distro kernels the output may not appear on the actual
|
||||
console, even though it will appear in the dmesg buffer, and be accessible
|
||||
via the dmesg command and to the consumers of /proc/kmsg. As a specific
|
||||
exception the header line from the sysrq command is passed to all console
|
||||
consumers as if the current loglevel was maximum. If only the header
|
||||
is emitted it is almost certain that the kernel loglevel is too low.
|
||||
Should you require the output on the console channel then you will need
|
||||
to temporarily up the console loglevel using alt-sysrq-8 or:
|
||||
|
||||
echo 8 > /proc/sysrq-trigger
|
||||
|
||||
Remember to return the loglevel to normal after triggering the sysrq
|
||||
command you are interested in.
