Date: Aug 2011
Contact: Nao Nishijima <nao.nishijima.xt@hitachi.com>
Description:
A raw device name of a disk does not always point a same disk
each boot-up time. Therefore, users have to use persistent
device names, which udev creates when the kernel finds a disk,
instead of raw device name. However, kernel doesn't show those
persistent names on its messages (e.g. dmesg).
This file can store an alias of the disk and it would be
appeared in kernel messages if it is set. A disk can have an
alias which length is up to 255bytes. Users can use alphabets,
numbers, "-" and "_" in alias name. This file is writeonce.

the /proc filesystem entry which the "block" side of the driver creates as
/proc/driver/cciss/cciss* at runtime. This is because at driver init time,
the SCSI core may not yet be initialized (because the driver is a block
driver) and attempting to register it with the SCSI core in such a case
would cause a hang. This is best done via an initialization script
(typically in /etc/init.d, but could vary depending on distribution).

@ -1,22 +1,24 @@
The I2C protocol knows about two kinds of device addresses: normal 7 bit
addresses, and an extended set of 10 bit addresses. The sets of addresses
do not intersect: the 7 bit address 0x10 is not the same as the 10 bit
address 0x10 (though a single device could respond to both of them). You
select a 10 bit address by adding an extra byte after the address
byte:
S Addr7 Rd/Wr ....

S 11110 Addr10 Rd/Wr
S is the start bit, Rd/Wr the read/write bit, and if you count the number
of bits, you will see the there are 8 after the S bit for 7 bit addresses,
and 16 after the S bit for 10 bit addresses.
address 0x10 (though a single device could respond to both of them).
WARNING! The current 10 bit address support is EXPERIMENTAL. There are
several places in the code that will cause SEVERE PROBLEMS with 10 bit
addresses, even though there is some basic handling and hooks. Also,
almost no supported adapter handles the 10 bit addresses correctly.
I2C messages to and from 10-bit address devices have a different format.
See the I2C specification for the details.
As soon as a real 10 bit address device is spotted 'in the wild', we
can and will add proper support. Right now, 10 bit address devices
are defined by the I2C protocol, but we have never seen a single device
which supports them.
The current 10 bit address support is minimal. It should work, however
you can expect some problems along the way:
* Not all bus drivers support 10-bit addresses. Some don't because the
hardware doesn't support them (SMBus doesn't require 10-bit address
support for example), some don't because nobody bothered adding the
code (or it's there but not working properly.) Software implementation
(i2c-algo-bit) is known to work.
* Some optional features do not support 10-bit addresses. This is the
case of automatic detection and instantiation of devices by their,
drivers, for example.
* Many user-space packages (for example i2c-tools) lack support for
10-bit addresses.
Note that 10-bit address devices are still pretty rare, so the limitations
listed above could stay for a long time, maybe even forever if nobody
needs them to be fixed.

All device objects in the driver model contain fields that control the handling
of system wakeup events (hardware signals that can force the system out of a
sleep state). These fields are initialized by bus or device driver code using
device_set_wakeup_capable() and device_set_wakeup_enable(), defined in
include/linux/pm_wakeup.h.
The "can_wakeup" flag just records whether the device (and its driver) can
The "power.can_wakeup" flag just records whether the device (and its driver) can
physically support wakeup events. The device_set_wakeup_capable() routine
affects this flag. The "should_wakeup" flag controls whether the device should
try to use its wakeup mechanism. device_set_wakeup_enable() affects this flag;
for the most part drivers should not change its value. The initial value of
should_wakeup is supposed to be false for the majority of devices; the major
exceptions are power buttons, keyboards, and Ethernet adapters whose WoL
(wake-on-LAN) feature has been set up with ethtool. It should also default
to true for devices that don't generate wakeup requests on their own but merely
forward wakeup requests from one bus to another (like PCI bridges).
affects this flag. The "power.wakeup" field is a pointer to an object of type
struct wakeup_source used for controlling whether or not the device should use
its system wakeup mechanism and for notifying the PM core of system wakeup
events signaled by the device. This object is only present for wakeup-capable
devices (i.e. devices whose "can_wakeup" flags are set) and is created (or
removed) by device_set_wakeup_capable().
Whether or not a device is capable of issuing wakeup events is a hardware
matter, and the kernel is responsible for keeping track of it. By contrast,
whether or not a wakeup-capable device should issue wakeup events is a policy
decision, and it is managed by user space through a sysfs attribute: the
power/wakeup file. User space can write the strings "enabled" or "disabled" to
set or clear the "should_wakeup" flag, respectively. This file is only present

"power/wakeup" file. User space can write the strings "enabled" or "disabled"
to it to indicate whether or not, respectively, the device is supposed to signal
system wakeup. This file is only present if the "power.wakeup" object exists
for the given device and is created (or removed) along with that object, by
device_set_wakeup_capable(). Reads from the file will return the corresponding
string.
The device_may_wakeup() routine returns true only if both flags are set.
The "power/wakeup" file is supposed to contain the "disabled" string initially
for the majority of devices; the major exceptions are power buttons, keyboards,
and Ethernet adapters whose WoL (wake-on-LAN) feature has been set up with
ethtool. It should also default to "enabled" for devices that don't generate
wakeup requests on their own but merely forward wakeup requests from one bus to
another (like PCI Express ports).
The device_may_wakeup() routine returns true only if the "power.wakeup" object
exists and the corresponding "power/wakeup" file contains the string "enabled".
This information is used by subsystems, like the PCI bus type code, to see
whether or not to enable the devices' wakeup mechanisms. If device wakeup
mechanisms are enabled or disabled directly by drivers, they also should use
device_may_wakeup() to decide what to do during a system sleep transition.
However for runtime power management, wakeup events should be enabled whenever
the device and driver both support them, regardless of the should_wakeup flag.
Device drivers, however, are not supposed to call device_set_wakeup_enable()
directly in any case.
It ought to be noted that system wakeup is conceptually different from "remote
wakeup" used by runtime power management, although it may be supported by the
same physical mechanism. Remote wakeup is a feature allowing devices in
low-power states to trigger specific interrupts to signal conditions in which
they should be put into the full-power state. Those interrupts may or may not
be used to signal system wakeup events, depending on the hardware design. On
some systems it is impossible to trigger them from system sleep states. In any
case, remote wakeup should always be enabled for runtime power management for
all devices and drivers that support it.

These callbacks are regarded by the PM core as mutually exclusive. Moreover,
PM domain callbacks always take precedence over bus, type and class callbacks,
while type callbacks take precedence over bus and class callbacks, and class
callbacks take precedence over bus callbacks. To be precise, the following
rules are used to determine which callback to execute in the given phase:
1. If dev->pm_domain is present, the PM core will attempt to execute the
callback included in dev->pm_domain->ops. If that callback is not
present, no action will be carried out for the given device.
2. Otherwise, if both dev->type and dev->type->pm are present, the callback
included in dev->type->pm will be executed.
3. Otherwise, if both dev->class and dev->class->pm are present, the
callback included in dev->class->pm will be executed.
4. Otherwise, if both dev->bus and dev->bus->pm are present, the callback
included in dev->bus->pm will be executed.

bool "PL310 errata: no automatic Store Buffer drain"
depends on CACHE_L2X0
help
On revisions of the PL310 prior to r3p2, the Store Buffer does
not automatically drain. This can cause normal, non-cacheable
writes to be retained when the memory system is idle, leading
to suboptimal I/O performance for drivers using coherent DMA.
This option adds a write barrier to the cpu_idle loop so that,
on systems with an outer cache, the store buffer is drained
explicitly.
