registering low-level, hardware specific driver to a hardware !Pdrivers/media/dvb-core/dvb_frontend.h Digital TV Frontend
independent demux layer. It is only of interest for Digital TV !Idrivers/media/dvb-core/dvb_frontend.h

<constant>demux.h</constant> and located in <sect1><title>Digital TV Demux kABI</title>

<sect1><title>Demux Callback API</title>
<para>The demux API should be implemented for each demux in the !Pdrivers/media/dvb-core/demux.h Demux Callback
system. It is used to select the TS source of a demux and to manage </sect1>
the demux resources. When the demux client allocates a resource via
the demux API, it receives a pointer to the API of that
resource.</para>
<para>Each demux receives its TS input from a DVB front-end or from
memory, as set via this demux API. In a system with more than one
front-end, the API can be used to select one of the DVB front-ends
as a TS source for a demux, unless this is fixed in the HW platform.
The demux API only controls front-ends regarding to their connections
with demuxes; the APIs used to set the other front-end parameters,
such as tuning, are not defined in this document.</para>
<para>The functions that implement the abstract interface demux should
be defined static or module private and registered to the Demux
core for external access. It is not necessary to implement every
function in the struct <constant>dmx_demux</constant>. For example,
a demux interface might support Section filtering, but not PES
filtering. The API client is expected to check the value of any
function pointer before calling the function: the value of NULL means
that the &#8220;function is not available&#8221;.</para>
<para>Whenever the functions of the demux API modify shared data,
the possibilities of lost update and race condition problems should
be addressed, e.g. by protecting parts of code with mutexes.</para>
<para>Note that functions called from a bottom half context must not
sleep. Even a simple memory allocation without using GFP_ATOMIC can
result in a kernel thread being put to sleep if swapping is needed.
For example, the Linux kernel calls the functions of a network device
interface from a bottom half context. Thus, if a demux API function
is called from network device code, the function must not sleep.
</para>
</sect1>
<section id="demux_callback_api">
<title>Demux Callback API</title>
<para>This kernel-space API comprises the callback functions that
deliver filtered data to the demux client. Unlike the other DVB
kABIs, these functions are provided by the client and called from
the demux code.</para>
<para>The function pointers of this abstract interface are not
packed into a structure as in the other demux APIs, because the
callback functions are registered and used independent of each
other. As an example, it is possible for the API client to provide
several callback functions for receiving TS packets and no
callbacks for PES packets or sections.</para>
<para>The functions that implement the callback API need not be
re-entrant: when a demux driver calls one of these functions,
the driver is not allowed to call the function again before
the original call returns. If a callback is triggered by a
hardware interrupt, it is recommended to use the Linux
&#8220;bottom half&#8221; mechanism or start a tasklet instead of
making the callback function call directly from a hardware
interrupt.</para>
<para>This mechanism is implemented by
<link linkend='API-dmx-ts-cb'>dmx_ts_cb()</link> and
<link linkend='API-dmx-section-cb'>dmx_section_cb()</link>.</para>

Silicon Errata and Software Workarounds
=======================================
Author: Will Deacon <will.deacon@arm.com>
Date : 27 November 2015
It is an unfortunate fact of life that hardware is often produced with
so-called "errata", which can cause it to deviate from the architecture
under specific circumstances. For hardware produced by ARM, these
errata are broadly classified into the following categories:
Category A: A critical error without a viable workaround.
Category B: A significant or critical error with an acceptable
workaround.
Category C: A minor error that is not expected to occur under normal
operation.
For more information, consult one of the "Software Developers Errata
Notice" documents available on infocenter.arm.com (registration
required).
As far as Linux is concerned, Category B errata may require some special
treatment in the operating system. For example, avoiding a particular
sequence of code, or configuring the processor in a particular way. A
less common situation may require similar actions in order to declassify
a Category A erratum into a Category C erratum. These are collectively
known as "software workarounds" and are only required in the minority of
cases (e.g. those cases that both require a non-secure workaround *and*
can be triggered by Linux).
For software workarounds that may adversely impact systems unaffected by
the erratum in question, a Kconfig entry is added under "Kernel
Features" -> "ARM errata workarounds via the alternatives framework".
These are enabled by default and patched in at runtime when an affected
CPU is detected. For less-intrusive workarounds, a Kconfig option is not
available and the code is structured (preferably with a comment) in such
a way that the erratum will not be hit.
This approach can make it slightly onerous to determine exactly which
errata are worked around in an arbitrary kernel source tree, so this
file acts as a registry of software workarounds in the Linux Kernel and
will be updated when new workarounds are committed and backported to
stable kernels.

Writeback
=========
Page cache is dirtied through buffered writes and shared mmaps and
written asynchronously to the backing filesystem by the writeback
mechanism. Writeback sits between the memory and IO domains and
regulates the proportion of dirty memory by balancing dirtying and
write IOs.
On traditional cgroup hierarchies, relationships between different
controllers cannot be established making it impossible for writeback
to operate accounting for cgroup resource restrictions and all
writeback IOs are attributed to the root cgroup.
If both the blkio and memory controllers are used on the v2 hierarchy
and the filesystem supports cgroup writeback, writeback operations
correctly follow the resource restrictions imposed by both memory and
blkio controllers.
Writeback examines both system-wide and per-cgroup dirty memory status
and enforces the more restrictive of the two. Also, writeback control
parameters which are absolute values - vm.dirty_bytes and
vm.dirty_background_bytes - are distributed across cgroups according
to their current writeback bandwidth.
There's a peculiarity stemming from the discrepancy in ownership
granularity between memory controller and writeback. While memory
controller tracks ownership per page, writeback operates on inode
basis. cgroup writeback bridges the gap by tracking ownership by
inode but migrating ownership if too many foreign pages, pages which
don't match the current inode ownership, have been encountered while
writing back the inode.
This is a conscious design choice as writeback operations are
inherently tied to inodes making strictly following page ownership
complicated and inefficient. The only use case which suffers from
this compromise is multiple cgroups concurrently dirtying disjoint
regions of the same inode, which is an unlikely use case and decided
to be unsupported. Note that as memory controller assigns page
ownership on the first use and doesn't update it until the page is
released, even if cgroup writeback strictly follows page ownership,
multiple cgroups dirtying overlapping areas wouldn't work as expected.
In general, write-sharing an inode across multiple cgroups is not well
supported.
Filesystem support for cgroup writeback
---------------------------------------
A filesystem can make writeback IOs cgroup-aware by updating
address_space_operations->writepage[s]() to annotate bio's using the
following two functions.
* wbc_init_bio(@wbc, @bio)
Should be called for each bio carrying writeback data and associates
the bio with the inode's owner cgroup. Can be called anytime
between bio allocation and submission.
* wbc_account_io(@wbc, @page, @bytes)
Should be called for each data segment being written out. While
this function doesn't care exactly when it's called during the
writeback session, it's the easiest and most natural to call it as
data segments are added to a bio.
With writeback bio's annotated, cgroup support can be enabled per
super_block by setting MS_CGROUPWB in ->s_flags. This allows for
selective disabling of cgroup writeback support which is helpful when
certain filesystem features, e.g. journaled data mode, are
incompatible.
wbc_init_bio() binds the specified bio to its cgroup. Depending on
the configuration, the bio may be executed at a lower priority and if
the writeback session is holding shared resources, e.g. a journal
entry, may lead to priority inversion. There is no one easy solution
for the problem. Filesystems can try to work around specific problem
cases by skipping wbc_init_bio() or using bio_associate_blkcg()
directly.

Do not verify blocks that are expected to contain zeroes and always return
zeroes instead. This may be useful if the partition contains unused blocks
that are not guaranteed to contain zeroes.

Use forward error correction (FEC) to recover from corruption if hash
verification fails. Use encoding data from the specified device. This
may be the same device where data and hash blocks reside, in which case
fec_start must be outside data and hash areas.
If the encoding data covers additional metadata, it must be accessible
on the hash device after the hash blocks.
Note: block sizes for data and hash devices must match. Also, if the
verity <dev> is encrypted the <fec_dev> should be too.

Number of generator roots. This equals to the number of parity bytes in
the encoding data. For example, in RS(M, N) encoding, the number of roots
is M-N.

Usage: optional
Value type: <prop-encoded-array>
Definition: A u32 value that represents the running time dynamic
power coefficient in units of mW/MHz/uVolt^2. The
coefficient can either be calculated from power
measurements or derived by analysis.
The dynamic power consumption of the CPU is
proportional to the square of the Voltage (V) and
the clock frequency (f). The coefficient is used to
calculate the dynamic power as below -
Pdyn = dynamic-power-coefficient * V^2 * f
where voltage is in uV, frequency is in MHz.

ARM cores often have a separate level 2 cache controller. There are various ARM cores often have a separate L2C210/L2C220/L2C310 (also known as PL210/PL220/
implementations of the L2 cache controller with compatible programming models. PL310 and variants) based level 2 cache controller. All these various implementations
