Regulator Proxy Consumer Bindings
Regulator proxy consumers provide a means to use a default regulator state

possible voltages and hardware requires that it be at a high level at the
beginning of boot before the consumer device responsible for requesting the
high level has probed.

This obviates the need to explicitly delete the link in the ``->remove``
callback or in the error path of the ``->probe`` callback.
Similarly, when the device link is added from supplier's ``->probe`` callback,
``DL_FLAG_AUTOREMOVE_SUPPLIER`` causes the device link to be automatically
purged when the supplier fails to probe or later unbinds.
If neither ``DL_FLAG_AUTOREMOVE_CONSUMER`` nor ``DL_FLAG_AUTOREMOVE_SUPPLIER``
is set, ``DL_FLAG_AUTOPROBE_CONSUMER`` can be used to request the driver core
to probe for a driver for the consumer driver on the link automatically after
a driver has been bound to the supplier device.
Note, however, that any combinations of ``DL_FLAG_AUTOREMOVE_CONSUMER``,
``DL_FLAG_AUTOREMOVE_SUPPLIER`` or ``DL_FLAG_AUTOPROBE_CONSUMER`` with
``DL_FLAG_STATELESS`` are invalid and cannot be used.
Limitations
===========
Driver authors should be aware that a driver presence dependency (i.e. when
``DL_FLAG_STATELESS`` is not specified on link addition) may cause probing of
the consumer to be deferred indefinitely. This can become a problem if the
consumer is required to probe before a certain initcall level is reached.
Worse, if the supplier driver is blacklisted or missing, the consumer will
never be probed.
Driver authors should be aware that a driver presence dependency for managed
device links (i.e. when ``DL_FLAG_STATELESS`` is not specified on link addition)
may cause probing of the consumer to be deferred indefinitely. This can become
a problem if the consumer is required to probe before a certain initcall level

Moreover, managed device links cannot be deleted directly. They are deleted
by the driver core when they are not necessary any more in accordance with the
``DL_FLAG_AUTOREMOVE_CONSUMER`` and ``DL_FLAG_AUTOREMOVE_SUPPLIER`` flags.
However, stateless device links (i.e. device links with ``DL_FLAG_STATELESS``
set) are expected to be removed by whoever called :c:func:`device_link_add()`
to add them with the help of either :c:func:`device_link_del()` or

urgently or not. Setting gc_urgent = 0 [default]
makes back to default behavior, while if it is set
to 1, background thread starts to do GC by given
gc_urgent_sleep_time interval.
reclaim_segments This parameter controls the number of prefree
segments to be reclaimed. If the number of prefree
segments is larger than the number of segments
in the proportion to the percentage over total

Compression implementation
--------------------------
- New term named cluster is defined as basic unit of compression, file can
be divided into multiple clusters logically. One cluster includes 4 << n
(n >= 0) logical pages, compression size is also cluster size, each of
cluster can be compressed or not.
- In cluster metadata layout, one special block address is used to indicate
cluster is compressed one or normal one, for compressed cluster, following
metadata maps cluster to [1, 4 << n - 1] physical blocks, in where f2fs
stores data including compress header and compressed data.
- In order to eliminate write amplification during overwrite, F2FS only
support compression on write-once file, data can be compressed only when
all logical blocks in file are valid and cluster compress ratio is lower
than specified threshold.
- To enable compression on regular inode, there are three ways:
* chattr +c file
* chattr +c dir; touch dir/file
* mount w/ -o compress_extension=ext; touch file.ext

Realtek PC Beep Hidden Register
===============================
This file documents the "PC Beep Hidden Register", which is present in certain
Realtek HDA codecs and controls a muxer and pair of passthrough mixers that can
route audio between pins but aren't themselves exposed as HDA widgets. As far
as I can tell, these hidden routes are designed to allow flexible PC Beep output
for codecs that don't have mixer widgets in their output paths. Why it's easier
to hide a mixer behind an undocumented vendor register than to just expose it
as a widget, I have no idea.
Register Description
====================
The register is accessed via processing coefficient 0x36 on NID 20h. Bits not
identified below have no discernible effect on my machine, a Dell XPS 13 9350::

1Ah input select (B): 2 bits
When zero, expose the PC Beep line (from the internal beep generator, when
enabled with the Set Beep Generation verb on NID 01h, or else from the
external PCBEEP pin) on the 1Ah pin node. When nonzero, expose the headphone
jack (or possibly Line In on some machines) input instead. If PC Beep is
selected, the 1Ah boost control has no effect.
Amplify 1Ah loopback, left (L): 1 bit
Amplify the left channel of 1Ah before mixing it into outputs as specified
by h and S bits. Does not affect the level of 1Ah exposed to other widgets.
Amplify 1Ah loopback, right (R): 1 bit
Amplify the right channel of 1Ah before mixing it into outputs as specified
by h and S bits. Does not affect the level of 1Ah exposed to other widgets.
Loopback 1Ah to 21h [active low] (h): 1 bit
When zero, mix 1Ah (possibly with amplification, depending on L and R bits)
into 21h (headphone jack on my machine). Mixed signal respects the mute
setting on 21h.
Loopback 1Ah to 14h (S): 1 bit
When one, mix 1Ah (possibly with amplification, depending on L and R bits)
into 14h (internal speaker on my machine). Mixed signal **ignores** the mute
setting on 14h and is present whenever 14h is configured as an output.

Background
==========
All Realtek HDA codecs have a vendor-defined widget with node ID 20h which
provides access to a bank of registers that control various codec functions.
Registers are read and written via the standard HDA processing coefficient
verbs (Set/Get Coefficient Index, Set/Get Processing Coefficient). The node is
named "Realtek Vendor Registers" in public datasheets' verb listings and,
apart from that, is entirely undocumented.
This particular register, exposed at coefficient 0x36 and named in commits from
Realtek, is of note: unlike most registers, which seem to control detailed
amplifier parameters not in scope of the HDA specification, it controls audio
routing which could just as easily have been defined using standard HDA mixer
and selector widgets.
Specifically, it selects between two sources for the input pin widget with Node
ID (NID) 1Ah: the widget's signal can come either from an audio jack (on my
laptop, a Dell XPS 13 9350, it's the headphone jack, but comments in Realtek
commits indicate that it might be a Line In on some machines) or from the PC
Beep line (which is itself multiplexed between the codec's internal beep
generator and external PCBEEP pin, depending on if the beep generator is
enabled via verbs on NID 01h). Additionally, it can mix (with optional
amplification) that signal onto the 21h and/or 14h output pins.
The register's reset value is 0x3717, corresponding to PC Beep on 1Ah that is
then amplified and mixed into both the headphones and the speakers. Not only
does this violate the HDA specification, which says that "[a vendor defined
beep input pin] connection may be maintained *only* while the Link reset
(**RST#**) is asserted", it means that we cannot ignore the register if we care
about the input that 1Ah would otherwise expose or if the PCBEEP trace is
poorly shielded and picks up chassis noise (both of which are the case on my
machine).
Unfortunately, there are lots of ways to get this register configuration wrong.
Linux, it seems, has gone through most of them. For one, the register resets
after S3 suspend: judging by existing code, this isn't the case for all vendor
registers, and it's led to some fixes that improve behavior on cold boot but
don't last after suspend. Other fixes have successfully switched the 1Ah input
away from PC Beep but have failed to disable both loopback paths. On my
machine, this means that the headphone input is amplified and looped back to
the headphone output, which uses the exact same pins! As you might expect, this
causes terrible headphone noise, the character of which is controlled by the
1Ah boost control. (If you've seen instructions online to fix XPS 13 headphone
noise by changing "Headphone Mic Boost" in ALSA, now you know why.)
The information here has been obtained through black-box reverse engineering of
the ALC256 codec's behavior and is not guaranteed to be correct. It likely
also applies for the ALC255, ALC257, ALC235, and ALC236, since those codecs
seem to be close relatives of the ALC256. (They all share one initialization
function.) Additionally, other codecs like the ALC225 and ALC285 also have this
register, judging by existing fixups in ``patch_realtek.c``, but specific
data (e.g. node IDs, bit positions, pin mappings) for those codecs may differ
from what I've described here.

USB Raw Gadget
==============
USB Raw Gadget is a kernel module that provides a userspace interface for
the USB Gadget subsystem. Essentially it allows to emulate USB devices
from userspace. Enabled with CONFIG_USB_RAW_GADGET. Raw Gadget is
currently a strictly debugging feature and shouldn't be used in
production, use GadgetFS instead.
Comparison to GadgetFS
~~~~~~~~~~~~~~~~~~~~~~
Raw Gadget is similar to GadgetFS, but provides a more low-level and
direct access to the USB Gadget layer for the userspace. The key
differences are:
1. Every USB request is passed to the userspace to get a response, while
GadgetFS responds to some USB requests internally based on the provided
descriptors. However note, that the UDC driver might respond to some
requests on its own and never forward them to the Gadget layer.
2. GadgetFS performs some sanity checks on the provided USB descriptors,
while Raw Gadget allows you to provide arbitrary data as responses to
USB requests.
3. Raw Gadget provides a way to select a UDC device/driver to bind to,
while GadgetFS currently binds to the first available UDC.
4. Raw Gadget uses predictable endpoint names (handles) across different
UDCs (as long as UDCs have enough endpoints of each required transfer
type).
5. Raw Gadget has ioctl-based interface instead of a filesystem-based one.
Userspace interface
~~~~~~~~~~~~~~~~~~~
To create a Raw Gadget instance open /dev/raw-gadget. Multiple raw-gadget
instances (bound to different UDCs) can be used at the same time. The
interaction with the opened file happens through the ioctl() calls, see
comments in include/uapi/linux/usb/raw_gadget.h for details.
The typical usage of Raw Gadget looks like:
1. Open Raw Gadget instance via /dev/raw-gadget.
2. Initialize the instance via USB_RAW_IOCTL_INIT.
3. Launch the instance with USB_RAW_IOCTL_RUN.
4. In a loop issue USB_RAW_IOCTL_EVENT_FETCH calls to receive events from
Raw Gadget and react to those depending on what kind of USB device
needs to be emulated.
Potential future improvements
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Implement ioctl's for setting/clearing halt status on endpoints.
- Reporting more events (suspend, resume, etc.) through
USB_RAW_IOCTL_EVENT_FETCH.
- Support O_NONBLOCK I/O.
