docs: ioctl-number.txt: convert it to ReST format
The conversion itself is simple: add a markup for the
title of this file and add markups for both tables.
Yet, the big table here with IOCTL numbers is badly formatted:
on several lines, the "Include File" column has some values that
are bigger than the reserved space there.
Also, on several places, a comment was misplaced at the "Include
File" space.
So, most of the work here is to actually ensure that each field
will be properly fixed.
Also worth to mention that some URLs have the asterisk character
on it. Well, Sphinx has an issue with asterisks in the middle
of an string. As this is URL, use the alternate format: %2A.
As a side effect of this patch, it is now a lot easier to see that
some reserved ioctl numbers are missing the include files
where it is supposed to be used.
PS.: While this is part of a subdir, I opted to convert this
single file alone, as this file has a potential of conflicts,
as most subsystem maintainers touch it.

If you are adding new ioctl's to the kernel, you should use the _IO
|
|
|
|
|
macros defined in <linux/ioctl.h>:
|
|
|
|
|
|
|
|
|
|
====== == ============================================
|
|
|
|
|
_IO an ioctl with no parameters
|
|
|
|
|
_IOW an ioctl with write parameters (copy_from_user)
|
|
|
|
|
_IOR an ioctl with read parameters (copy_to_user)
|
|
|
|
|
_IOWR an ioctl with both write and read parameters.
|
|
|
|
|
====== == ============================================
|
|
|
|
|
|
|
|
|
|
'Write' and 'read' are from the user's point of view, just like the
|
|
|
|
|
system calls 'write' and 'read'. For example, a SET_FOO ioctl would
|
|
|
|
|
be _IOW, although the kernel would actually read data from user space;
|
|
|
|
|
a GET_FOO ioctl would be _IOR, although the kernel would actually write
|
|
|
|
|
data to user space.
|
|
|
|
|
|
|
|
|
|
The first argument to _IO, _IOW, _IOR, or _IOWR is an identifying letter
|
|
|
|
|
or number from the table below. Because of the large number of drivers,
|
|
|
|
|
many drivers share a partial letter with other drivers.
|
|
|
|
|
|
|
|
|
|
If you are writing a driver for a new device and need a letter, pick an
|
|
|
|
|
unused block with enough room for expansion: 32 to 256 ioctl commands.
|
|
|
|
|
You can register the block by patching this file and submitting the
|
|
|
|
|
patch to Linus Torvalds. Or you can e-mail me at <mec@shout.net> and
|
|
|
|
|
I'll register one for you.
|
|
|
|
|
|
|
|
|
|
The second argument to _IO, _IOW, _IOR, or _IOWR is a sequence number
|
|
|
|
|
to distinguish ioctls from each other. The third argument to _IOW,
|
|
|
|
|
_IOR, or _IOWR is the type of the data going into the kernel or coming
|
|
|
|
|
out of the kernel (e.g. 'int' or 'struct foo'). NOTE! Do NOT use
|
|
|
|
|
sizeof(arg) as the third argument as this results in your ioctl thinking
|
|
|
|
|
it passes an argument of type size_t.
|
|
|
|
|
|
|
|
|
|
Some devices use their major number as the identifier; this is OK, as
|
|
|
|
|
long as it is unique. Some devices are irregular and don't follow any
|
|
|
|
|
convention at all.
|
|
|
|
|
|
|
|
|
|
Following this convention is good because:
|
|
|
|
|
|
|
|
|
|
(1) Keeping the ioctl's globally unique helps error checking:
|
|
|
|
|
if a program calls an ioctl on the wrong device, it will get an
|
|
|
|
|
error rather than some unexpected behaviour.
|
|
|
|
|
|
|
|
|
|
(2) The 'strace' build procedure automatically finds ioctl numbers
|
|
|
|
|
defined with _IO, _IOW, _IOR, or _IOWR.
|
|
|
|
|
|
|
|
|
|
(3) 'strace' can decode numbers back into useful names when the
|
|
|
|
|
numbers are unique.
|
|
|
|
|
|
|
|
|
|
(4) People looking for ioctls can grep for them more easily when
|
|
|
|
|
this convention is used to define the ioctl numbers.
|
|
|
|
|
|
|
|
|
|
(5) When following the convention, the driver code can use generic
|
|
|
|
|
code to copy the parameters between user and kernel space.
|
|
|
|
|
|
|
|
|
|
This table lists ioctls visible from user land for Linux/x86. It contains
|
|
|
|
|
most drivers up to 2.6.31, but I know I am missing some. There has been
|
|
|
|
|
no attempt to list non-X86 architectures or ioctls from drivers/staging/.

pipe: Add general notification queue support
Make it possible to have a general notification queue built on top of a
standard pipe. Notifications are 'spliced' into the pipe and then read
out. splice(), vmsplice() and sendfile() are forbidden on pipes used for
notifications as post_one_notification() cannot take pipe->mutex. This
means that notifications could be posted in between individual pipe
buffers, making iov_iter_revert() difficult to effect.
The way the notification queue is used is:
(1) An application opens a pipe with a special flag and indicates the
number of messages it wishes to be able to queue at once (this can
only be set once):
pipe2(fds, O_NOTIFICATION_PIPE);
ioctl(fds[0], IOC_WATCH_QUEUE_SET_SIZE, queue_depth);
(2) The application then uses poll() and read() as normal to extract data
from the pipe. read() will return multiple notifications if the
buffer is big enough, but it will not split a notification across
buffers - rather it will return a short read or EMSGSIZE.
Notification messages include a length in the header so that the
caller can split them up.
Each message has a header that describes it:
struct watch_notification {
__u32 type:24;
__u32 subtype:8;
__u32 info;
};
The type indicates the source (eg. mount tree changes, superblock events,
keyring changes, block layer events) and the subtype indicates the event
type (eg. mount, unmount; EIO, EDQUOT; link, unlink). The info field
indicates a number of things, including the entry length, an ID assigned to
a watchpoint contributing to this buffer and type-specific flags.
Supplementary data, such as the key ID that generated an event, can be
attached in additional slots. The maximum message size is 127 bytes.
Messages may not be padded or aligned, so there is no guarantee, for
example, that the notification type will be on a 4-byte bounary.

docs: ioctl-number.txt: convert it to ReST format
The conversion itself is simple: add a markup for the
title of this file and add markups for both tables.
Yet, the big table here with IOCTL numbers is badly formatted:
on several lines, the "Include File" column has some values that
are bigger than the reserved space there.
Also, on several places, a comment was misplaced at the "Include
File" space.
So, most of the work here is to actually ensure that each field
will be properly fixed.
Also worth to mention that some URLs have the asterisk character
on it. Well, Sphinx has an issue with asterisks in the middle
of an string. As this is URL, use the alternate format: %2A.
As a side effect of this patch, it is now a lot easier to see that
some reserved ioctl numbers are missing the include files
where it is supposed to be used.
PS.: While this is part of a subdir, I opted to convert this

platform/surface: Add DTX driver
The Microsoft Surface Book series devices consist of a so-called
clipboard part (containing the CPU, touchscreen, and primary battery)
and a base part (containing keyboard, secondary battery, and optional
discrete GPU). These parts can be separated, i.e. the clipboard can be
detached and used as tablet.
This detachment process is initiated by pressing a button. On the
Surface Book 2 and 3 (targeted with this commit), the Surface Aggregator
Module (i.e. the embedded controller on those devices) attempts to send
a notification to any listening client driver and waits for further
instructions (i.e. whether the detachment process should continue or be
aborted). If it does not receive a response in a certain time-frame, the
detachment process (by default) continues and the clipboard can be
physically separated. In other words, (by default and) without a driver,
the detachment process takes about 10 seconds to complete.
This commit introduces a driver for this detachment system (called DTX).
This driver allows a user-space daemon to control and influence the
detachment behavior. Specifically, it forwards any detachment requests
to user-space, allows user-space to make such requests itself, and
allows handling of those requests. Requests can be handled by either
aborting, continuing/allowing, or delaying (i.e. resetting the timeout
via a heartbeat commend). The user-space API is implemented via the
/dev/surface/dtx miscdevice.
In addition, user-space can change the default behavior on timeout from
allowing detachment to disallowing it, which is useful if the (optional)
discrete GPU is in use.
Furthermore, this driver allows user-space to receive notifications
about the state of the base, specifically when it is physically removed
(as opposed to detachment requested), in what manner it is connected
(i.e. in reverse-/tent-/studio- or laptop-mode), and what type of base
is connected. Based on this information, the driver also provides a
simple tablet-mode switch (aliasing all modes without keyboard access,
i.e. tablet-mode and studio-mode to its reported tablet-mode).
An implementation of such a user-space daemon, allowing configuration of
detachment behavior via scripts (e.g. safely unmounting USB devices
connected to the base before continuing) can be found at [1].

docs: ioctl-number.txt: convert it to ReST format
The conversion itself is simple: add a markup for the
title of this file and add markups for both tables.
Yet, the big table here with IOCTL numbers is badly formatted:
on several lines, the "Include File" column has some values that
are bigger than the reserved space there.
Also, on several places, a comment was misplaced at the "Include
File" space.
So, most of the work here is to actually ensure that each field
will be properly fixed.
Also worth to mention that some URLs have the asterisk character
on it. Well, Sphinx has an issue with asterisks in the middle
of an string. As this is URL, use the alternate format: %2A.
As a side effect of this patch, it is now a lot easier to see that
some reserved ioctl numbers are missing the include files
where it is supposed to be used.
PS.: While this is part of a subdir, I opted to convert this
single file alone, as this file has a potential of conflicts,
as most subsystem maintainers touch it.
