persistent names on its messages (e.g. dmesg).

Perhaps the most important GEM function is providing a command

buffers containing references to previously allocated memory objects,

all the objects into the GTT, execute the buffer, and provide

necessary synchronization between clients accessing the same buffers.
|
||||
This often involves evicting some objects from the GTT and re-binding
|

others (a fairly expensive operation), and providing relocation
|

support which hides fixed GTT offsets from clients. Clients must

take care not to submit command buffers that reference more objects

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.

-----------------------------------

All devices in the driver model have two flags to control handling of wakeup
|
||||
events (hardware signals that can force the device and/or system out of a low
|
||||
power state). These flags are initialized by bus or device driver code using
|
||||
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
|
||||
for wakeup-capable devices (i.e. devices whose "can_wakeup" flags are set)
|
||||
and is created (or removed) by device_set_wakeup_capable(). Reads from the
|
||||
file will return the corresponding string.
|
||||
"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.

1. If dev->pm_domain is present, the PM core will attempt to execute the

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.
