5.5 usage_in_bytes

For efficiency, as other kernel components, memory cgroup uses some optimization
to avoid unnecessary cacheline false sharing. usage_in_bytes is affected by the
method and doesn't show 'exact' value of memory(and swap) usage, it's an fuzz
value for efficient access. (Of course, when necessary, it's synchronized.)
If you want to know more exact memory usage, you should use RSS+CACHE(+SWAP)
value in memory.stat(see 5.2).

The memory controller supports a deep hierarchy and hierarchical accounting.

Xeon support
------------

Some Xeon processors have real max1617, adm1021, or compatible chips
within them, with two temperature sensors.
Netburst-based Xeon support
---------------------------

Other Xeons have chips with only one sensor.
Some Xeon processors based on the Netburst (early Pentium 4, from 2001 to
2003) microarchitecture had real MAX1617, ADM1021, or compatible chips
within them, with two temperature sensors. Other Xeon processors of this
era (with 400 MHz FSB) had chips with only one temperature sensor.

If you have a Xeon, and the adm1021 module loads, and both temperatures
appear valid, then things are good.
If you have such an old Xeon, and you get two valid temperatures when
loading the adm1021 module, then things are good.

If the adm1021 module doesn't load, you should try this:
modprobe adm1021 force_adm1021=BUS,ADDRESS
ADDRESS can only be 0x18, 0x1a, 0x29, 0x2b, 0x4c, or 0x4e.
If nothing happens when loading the adm1021 module, and you are certain
that your specific Xeon processor model includes compatible sensors, you
will have to explicitly instantiate the sensor chips from user-space. See
method 4 in Documentation/i2c/instantiating-devices. Possible slave
addresses are 0x18, 0x1a, 0x29, 0x2b, 0x4c, or 0x4e. It is likely that
only temp2 will be correct and temp1 will have to be ignored.

If you have dual Xeons you may have appear to have two separate
adm1021-compatible chips, or two single-temperature sensors, at distinct
addresses.
Previous generations of the Xeon processor (based on Pentium II/III)
didn't have these sensors. Next generations of Xeon processors (533 MHz
FSB and faster) lost them, until the Core-based generation which
introduced integrated digital thermal sensors. These are supported by
the coretemp driver.

SMBus Alert Support
-------------------

This driver has basic support for SMBus alert. When an alert is received,
the status register is read and the faulty temperature channel is logged.

The Analog Devices chips (ADM1032 and ADT7461) do not implement the SMBus
alert protocol properly so additional care is needed: the ALERT output is
disabled when an alert is received, and is re-enabled only when the alarm
is gone. Otherwise the chip would block alerts from other chips in the bus
as long as the alarm is active.

Description
-----------

This driver supports hardware montoring for Maxim MAX16064 Quad Power-Supply
Controller with Active-Voltage Output Control and PMBus Interface.

The driver is a client driver to the core PMBus driver.
Please see Documentation/hwmon/pmbus for details on PMBus client drivers.


Usage Notes
-----------

This driver does not auto-detect devices. You will have to instantiate the
devices explicitly. Please see Documentation/i2c/instantiating-devices for
details.


Platform data support
---------------------

The driver supports standard PMBus driver platform data.
