Description: Default value for the Data Stream Control Register (DSCR) on
a CPU.
This default value is used when the kernel is executing and
for any process that has not set the DSCR itself.
If a process ever sets the DSCR (via direct access to the
SPR) that value will be persisted for that process and used
on any CPU where it executes (overriding the value described
here).
If set by a process it will be inherited by child processes.
Values: 64 bit unsigned integer (bit field)

What: /sys/class/net/<iface>/cdc_ncm/min_tx_pkt
Date: May 2014
KernelVersion: 3.16
Contact: Bjørn Mork <bjorn@mork.no>
Description:
The driver will pad NCM Transfer Blocks (NTBs) longer
than this to tx_max, allowing the device to receive
tx_max sized frames with no terminating short
packet. NTBs shorter than this limit are transmitted
as-is, without any padding, and are terminated with a
short USB packet.
Padding to tx_max allows the driver to transmit NTBs
back-to-back without any interleaving short USB
packets. This reduces the number of short packet
interrupts in the device, and represents a tradeoff
between USB bus bandwidth and device DMA optimization.
Set to 0 to pad all frames. Set greater than tx_max to
disable all padding.

The /sys/power/state file controls the system power state.
Reading from this file returns what states are supported,
which is hard-coded to 'freeze' (Low-Power Idle), 'standby'
(Power-On Suspend), 'mem' (Suspend-to-RAM), and 'disk'
(Suspend-to-Disk).
The /sys/power/state file controls system sleep states.
Reading from this file returns the available sleep state
labels, which may be "mem", "standby", "freeze" and "disk"
(hibernation). The meanings of the first three labels depend on
the relative_sleep_states command line argument as follows:
1) relative_sleep_states = 1
"mem", "standby", "freeze" represent non-hibernation sleep
states from the deepest ("mem", always present) to the
shallowest ("freeze"). "standby" and "freeze" may or may
not be present depending on the capabilities of the
platform. "freeze" can only be present if "standby" is
present.
2) relative_sleep_states = 0 (default)
"mem" - "suspend-to-RAM", present if supported.
"standby" - "power-on suspend", present if supported.
"freeze" - "suspend-to-idle", always present.

messages should be compiled out when the DEBUG symbol is not defined (that
is, by default they are not included). When you use dev_dbg() or pr_debug(),

you have them, they can be a huge help for remote troubleshooting. However
debug message printing is handled differently than printing other non-debug
messages. While the other pr_XXX() functions print unconditionally,
pr_debug() does not; it is compiled out by default, unless either DEBUG is
defined or CONFIG_DYNAMIC_DEBUG is set. That is true for dev_dbg() also,
and a related convention uses VERBOSE_DEBUG to add dev_vdbg() messages to
the ones already enabled by DEBUG.
Many subsystems have Kconfig debug options to turn on -DDEBUG in the
corresponding Makefile; in other cases specific files #define DEBUG. And
when a debug message should be unconditionally printed, such as if it is
already inside a debug-related #ifdef secton, printk(KERN_DEBUG ...) can be
used.

UEFI, the Unified Extensible Firmware Interface, is a specification
governing the behaviours of compatible firmware interfaces. It is
maintained by the UEFI Forum - http://www.uefi.org/.
UEFI is an evolution of its predecessor 'EFI', so the terms EFI and
UEFI are used somewhat interchangeably in this document and associated
source code. As a rule, anything new uses 'UEFI', whereas 'EFI' refers
to legacy code or specifications.
UEFI support in Linux
=====================
Booting on a platform with firmware compliant with the UEFI specification
makes it possible for the kernel to support additional features:
- UEFI Runtime Services
- Retrieving various configuration information through the standardised
interface of UEFI configuration tables. (ACPI, SMBIOS, ...)
For actually enabling [U]EFI support, enable:
- CONFIG_EFI=y
- CONFIG_EFI_VARS=y or m
The implementation depends on receiving information about the UEFI environment
in a Flattened Device Tree (FDT) - so is only available with CONFIG_OF.
UEFI stub
=========
The "stub" is a feature that extends the Image/zImage into a valid UEFI
PE/COFF executable, including a loader application that makes it possible to
load the kernel directly from the UEFI shell, boot menu, or one of the
lightweight bootloaders like Gummiboot or rEFInd.
The kernel image built with stub support remains a valid kernel image for
booting in non-UEFI environments.
UEFI kernel support on ARM
==========================
UEFI kernel support on the ARM architectures (arm and arm64) is only available
when boot is performed through the stub.
When booting in UEFI mode, the stub deletes any memory nodes from a provided DT.
Instead, the kernel reads the UEFI memory map.
The stub populates the FDT /chosen node with (and the kernel scans for) the
following parameters:
________________________________________________________________________________
Name | Size | Description
================================================================================
linux,uefi-system-table | 64-bit | Physical address of the UEFI System Table.

linux,uefi-mmap-start | 64-bit | Physical address of the UEFI memory map,
| | populated by the UEFI GetMemoryMap() call.

1. Background
cgroup allows an arbitrary number of hierarchies and each hierarchy
can host any number of controllers. While this seems to provide a
high level of flexibility, it isn't quite useful in practice.
For example, as there is only one instance of each controller, utility
type controllers such as freezer which can be useful in all
hierarchies can only be used in one. The issue is exacerbated by the
fact that controllers can't be moved around once hierarchies are
populated. Another issue is that all controllers bound to a hierarchy
are forced to have exactly the same view of the hierarchy. It isn't
possible to vary the granularity depending on the specific controller.
In practice, these issues heavily limit which controllers can be put
on the same hierarchy and most configurations resort to putting each
controller on its own hierarchy. Only closely related ones, such as
the cpu and cpuacct controllers, make sense to put on the same
hierarchy. This often means that userland ends up managing multiple
similar hierarchies repeating the same steps on each hierarchy
whenever a hierarchy management operation is necessary.
Unfortunately, support for multiple hierarchies comes at a steep cost.
Internal implementation in cgroup core proper is dazzlingly
complicated but more importantly the support for multiple hierarchies
restricts how cgroup is used in general and what controllers can do.
There's no limit on how many hierarchies there may be, which means
that a task's cgroup membership can't be described in finite length.
The key may contain any varying number of entries and is unlimited in
length, which makes it highly awkward to handle and leads to addition
of controllers which exist only to identify membership, which in turn
exacerbates the original problem.
Also, as a controller can't have any expectation regarding what shape
of hierarchies other controllers would be on, each controller has to
assume that all other controllers are operating on completely
orthogonal hierarchies. This makes it impossible, or at least very
cumbersome, for controllers to cooperate with each other.
In most use cases, putting controllers on hierarchies which are
completely orthogonal to each other isn't necessary. What usually is
called for is the ability to have differing levels of granularity
depending on the specific controller. In other words, hierarchy may
be collapsed from leaf towards root when viewed from specific
controllers. For example, a given configuration might not care about
how memory is distributed beyond a certain level while still wanting
to control how CPU cycles are distributed.
Unified hierarchy is the next version of cgroup interface. It aims to
address the aforementioned issues by having more structure while
retaining enough flexibility for most use cases. Various other
general and controller-specific interface issues are also addressed in
the process.
2. Basic Operation
2-1. Mounting
Currently, unified hierarchy can be mounted with the following mount
command. Note that this is still under development and scheduled to
change soon.
mount -t cgroup -o __DEVEL__sane_behavior cgroup $MOUNT_POINT
All controllers which are not bound to other hierarchies are
automatically bound to unified hierarchy and show up at the root of
it. Controllers which are enabled only in the root of unified
hierarchy can be bound to other hierarchies at any time. This allows
mixing unified hierarchy with the traditional multiple hierarchies in
a fully backward compatible way.
2-2. cgroup.subtree_control
All cgroups on unified hierarchy have a "cgroup.subtree_control" file
which governs which controllers are enabled on the children of the
cgroup. Let's assume a hierarchy like the following.
root - A - B - C
\ D
root's "cgroup.subtree_control" file determines which controllers are
enabled on A. A's on B. B's on C and D. This coincides with the
fact that controllers on the immediate sub-level are used to
distribute the resources of the parent. In fact, it's natural to
assume that resource control knobs of a child belong to its parent.
Enabling a controller in a "cgroup.subtree_control" file declares that
distribution of the respective resources of the cgroup will be
controlled. Note that this means that controller enable states are
shared among siblings.
When read, the file contains a space-separated list of currently
enabled controllers. A write to the file should contain a
space-separated list of controllers with '+' or '-' prefixed (without
the quotes). Controllers prefixed with '+' are enabled and '-'
disabled. If a controller is listed multiple times, the last entry
wins. The specific operations are executed atomically - either all
succeed or fail.
2-3. cgroup.controllers
Read-only "cgroup.controllers" file contains a space-separated list of
controllers which can be enabled in the cgroup's
"cgroup.subtree_control" file.
In the root cgroup, this lists controllers which are not bound to
other hierarchies and the content changes as controllers are bound to
and unbound from other hierarchies.
In non-root cgroups, the content of this file equals that of the
parent's "cgroup.subtree_control" file as only controllers enabled
from the parent can be used in its children.
3. Structural Constraints
3-1. Top-down
As it doesn't make sense to nest control of an uncontrolled resource,
all non-root "cgroup.subtree_control" files can only contain
controllers which are enabled in the parent's "cgroup.subtree_control"
file. A controller can be enabled only if the parent has the
controller enabled and a controller can't be disabled if one or more
children have it enabled.
3-2. No internal tasks
One long-standing issue that cgroup faces is the competition between
tasks belonging to the parent cgroup and its children cgroups. This
is inherently nasty as two different types of entities compete and
there is no agreed-upon obvious way to handle it. Different
controllers are doing different things.
The cpu controller considers tasks and cgroups as equivalents and maps
nice levels to cgroup weights. This works for some cases but falls
flat when children should be allocated specific ratios of CPU cycles
and the number of internal tasks fluctuates - the ratios constantly
change as the number of competing entities fluctuates. There also are
other issues. The mapping from nice level to weight isn't obvious or
universal, and there are various other knobs which simply aren't
available for tasks.
The blkio controller implicitly creates a hidden leaf node for each
cgroup to host the tasks. The hidden leaf has its own copies of all
the knobs with "leaf_" prefixed. While this allows equivalent control
over internal tasks, it's with serious drawbacks. It always adds an
extra layer of nesting which may not be necessary, makes the interface
messy and significantly complicates the implementation.
The memory controller currently doesn't have a way to control what
happens between internal tasks and child cgroups and the behavior is
not clearly defined. There have been attempts to add ad-hoc behaviors
and knobs to tailor the behavior to specific workloads. Continuing
this direction will lead to problems which will be extremely difficult
to resolve in the long term.
Multiple controllers struggle with internal tasks and came up with
different ways to deal with it; unfortunately, all the approaches in
use now are severely flawed and, furthermore, the widely different
behaviors make cgroup as whole highly inconsistent.
It is clear that this is something which needs to be addressed from
cgroup core proper in a uniform way so that controllers don't need to
worry about it and cgroup as a whole shows a consistent and logical
behavior. To achieve that, unified hierarchy enforces the following
structural constraint:
Except for the root, only cgroups which don't contain any task may
have controllers enabled in their "cgroup.subtree_control" files.
Combined with other properties, this guarantees that, when a
controller is looking at the part of the hierarchy which has it
enabled, tasks are always only on the leaves. This rules out
situations where child cgroups compete against internal tasks of the
parent.
There are two things to note. Firstly, the root cgroup is exempt from
the restriction. Root contains tasks and anonymous resource
consumption which can't be associated with any other cgroup and
requires special treatment from most controllers. How resource
consumption in the root cgroup is governed is up to each controller.
Secondly, the restriction doesn't take effect if there is no enabled
controller in the cgroup's "cgroup.subtree_control" file. This is
important as otherwise it wouldn't be possible to create children of a
populated cgroup. To control resource distribution of a cgroup, the
cgroup must create children and transfer all its tasks to the children
before enabling controllers in its "cgroup.subtree_control" file.
4. Other Changes
4-1. [Un]populated Notification
cgroup users often need a way to determine when a cgroup's
subhierarchy becomes empty so that it can be cleaned up. cgroup
currently provides release_agent for it; unfortunately, this mechanism
is riddled with issues.
- It delivers events by forking and execing a userland binary
specified as the release_agent. This is a long deprecated method of
notification delivery. It's extremely heavy, slow and cumbersome to
integrate with larger infrastructure.
- There is single monitoring point at the root. There's no way to
delegate management of a subtree.
- The event isn't recursive. It triggers when a cgroup doesn't have
any tasks or child cgroups. Events for internal nodes trigger only
after all children are removed. This again makes it impossible to
delegate management of a subtree.
- Events are filtered from the kernel side. A "notify_on_release"
file is used to subscribe to or suppress release events. This is
unnecessarily complicated and probably done this way because event
delivery itself was expensive.
Unified hierarchy implements an interface file "cgroup.populated"
which can be used to monitor whether the cgroup's subhierarchy has
tasks in it or not. Its value is 0 if there is no task in the cgroup
and its descendants; otherwise, 1. poll and [id]notify events are
triggered when the value changes.
This is significantly lighter and simpler and trivially allows
delegating management of subhierarchy - subhierarchy monitoring can
block further propagation simply by putting itself or another process
in the subhierarchy and monitor events that it's interested in from
there without interfering with monitoring higher in the tree.
In unified hierarchy, the release_agent mechanism is no longer
supported and the interface files "release_agent" and
"notify_on_release" do not exist.
4-2. Other Core Changes
- None of the mount options is allowed.
- remount is disallowed.
- rename(2) is disallowed.
- The "tasks" file is removed. Everything should at process
granularity. Use the "cgroup.procs" file instead.
- The "cgroup.procs" file is not sorted. pids will be unique unless
they got recycled in-between reads.
- The "cgroup.clone_children" file is removed.
4-3. Per-Controller Changes
4-3-1. blkio
- blk-throttle becomes properly hierarchical.
4-3-2. cpuset
- Tasks are kept in empty cpusets after hotplug and take on the masks
of the nearest non-empty ancestor, instead of being moved to it.
- A task can be moved into an empty cpuset, and again it takes on the
masks of the nearest non-empty ancestor.
4-3-3. memory
- use_hierarchy is on by default and the cgroup file for the flag is
not created.
5. Planned Changes
5-1. CAP for resource control
Unified hierarchy will require one of the capabilities(7), which is
yet to be decided, for all resource control related knobs. Process
organization operations - creation of sub-cgroups and migration of
processes in sub-hierarchies may be delegated by changing the
ownership and/or permissions on the cgroup directory and
"cgroup.procs" interface file; however, all operations which affect
resource control - writes to a "cgroup.subtree_control" file or any
controller-specific knobs - will require an explicit CAP privilege.
This, in part, is to prevent the cgroup interface from being
inadvertently promoted to programmable API used by non-privileged
binaries. cgroup exposes various aspects of the system in ways which
aren't properly abstracted for direct consumption by regular programs.
This is an administration interface much closer to sysctl knobs than
system calls. Even the basic access model, being filesystem path
based, isn't suitable for direct consumption. There's no way to
access "my cgroup" in a race-free way or make multiple operations
atomic against migration to another cgroup.
Another aspect is that, for better or for worse, the cgroup interface
goes through far less scrutiny than regular interfaces for
unprivileged userland. The upside is that cgroup is able to expose
useful features which may not be suitable for general consumption in a
reasonable time frame. It provides a relatively short path between
internal details and userland-visible interface. Of course, this
shortcut comes with high risk. We go through what we go through for
general kernel APIs for good reasons. It may end up leaking internal
details in a way which can exert significant pain by locking the
kernel into a contract that can't be maintained in a reasonable
manner.
Also, due to the specific nature, cgroup and its controllers don't
tend to attract attention from a wide scope of developers. cgroup's
short history is already fraught with severely mis-designed
interfaces, unnecessary commitments to and exposing of internal
details, broken and dangerous implementations of various features.
Keeping cgroup as an administration interface is both advantageous for
its role and imperative given its nature. Some of the cgroup features
may make sense for unprivileged access. If deemed justified, those
must be further abstracted and implemented as a different interface,
be it a system call or process-private filesystem, and survive through
the scrutiny that any interface for general consumption is required to
go through.
Requiring CAP is not a complete solution but should serve as a
significant deterrent against spraying cgroup usages in non-privileged
programs.

Device Tree Clock bindings for ATL (Audio Tracking Logic) of DRA7 SoC.
The ATL IP is used to generate clock to be used to synchronize baseband and
audio codec. A single ATL IP provides four ATL clock instances sharing the same
functional clock but can be configured to provide different clocks.
ATL can maintain a clock averages to some desired frequency based on the bws/aws
signals - can compensate the drift between the two ws signal.
In order to provide the support for ATL and it's output clocks (which can be used
internally within the SoC or external components) two sets of bindings is needed:
Clock tree binding:
This binding uses the common clock binding[1].
To be able to integrate the ATL clocks with DT clock tree.
Provides ccf level representation of the ATL clocks to be used by drivers.
Since the clock instances are part of a single IP this binding is used as a node
for the DT clock tree, the IP driver is needed to handle the actual configuration
of the IP.

Samsung Exynos IOMMU H/W, System MMU (System Memory Management Unit)
Samsung's Exynos architecture contains System MMUs that enables scattered
physical memory chunks visible as a contiguous region to DMA-capable peripheral
devices like MFC, FIMC, FIMD, GScaler, FIMC-IS and so forth.
System MMU is an IOMMU and supports identical translation table format to
ARMv7 translation tables with minimum set of page properties including access
permissions, shareability and security protection. In addition, System MMU has
another capabilities like L2 TLB or block-fetch buffers to minimize translation
latency.
System MMUs are in many to one relation with peripheral devices, i.e. single
peripheral device might have multiple System MMUs (usually one for each bus
master), but one System MMU can handle transactions from only one peripheral
device. The relation between a System MMU and the peripheral device needs to be
defined in device node of the peripheral device.
MFC in all Exynos SoCs and FIMD, M2M Scalers and G2D in Exynos5420 has 2 System
MMUs.
* MFC has one System MMU on its left and right bus.
* FIMD in Exynos5420 has one System MMU for window 0 and 4, the other system MMU
for window 1, 2 and 3.
* M2M Scalers and G2D in Exynos5420 has one System MMU on the read channel and
the other System MMU on the write channel.
The drivers must consider how to handle those System MMUs. One of the idea is
to implement child devices or sub-devices which are the client devices of the
System MMU.
Note:
The current DT binding for the Exynos System MMU is incomplete.
The following properties can be removed or changed, if found incompatible with
the "Generic IOMMU Binding" support for attaching devices to the IOMMU.
Required properties:
- compatible: Should be "samsung,exynos-sysmmu"
- reg: A tuple of base address and size of System MMU registers.
- interrupt-parent: The phandle of the interrupt controller of System MMU
- interrupts: An interrupt specifier for interrupt signal of System MMU,
according to the format defined by a particular interrupt
controller.
- clock-names: Should be "sysmmu" if the System MMU is needed to gate its clock.
Optional "master" if the clock to the System MMU is gated by
another gate clock other than "sysmmu".
Exynos4 SoCs, there needs no "master" clock.
Exynos5 SoCs, some System MMUs must have "master" clocks.
- clocks: Required if the System MMU is needed to gate its clock.
- samsung,power-domain: Required if the System MMU is needed to gate its power.
Please refer to the following document:
Documentation/devicetree/bindings/arm/exynos/power_domain.txt
