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/.

USB: cdc-wdm: implement IOCTL_WDM_MAX_COMMAND
Userspace applications need to know the maximum supported message
size.
The cdc-wdm driver translates between a character device stream
and a message based protocol. Each message is transported as a
usb control message with no further encapsulation or syncronization.
Each read or write on the character device should translate to
exactly one usb control message to ensure that message boundaries
are kept intact. That means that the userspace application must
know the maximum message size supported by the device and driver,
making this size a vital part of the cdc-wdm character device API.
CDC WDM and CDC MBIM functions export the maximum supported
message size through CDC functional descriptors. The cdc-wdm and
cdc_mbim drivers will parse these descriptors and use the value
chosen by the device. The only current way for a userspace
application to retrive the value is by duplicating the descriptor
parsing. This is an unnecessary complex task, and application
writers are likely to postpone it, using a fixed value and adding
a "todo" item.
QMI functions have no way to tell the host what message size they
support. The qmi_wwan driver use a fixed value based on protocol
recommendations and observed device behaviour. Userspace
applications must know and hard code the same value. This scheme
will break if we ever encounter a QMI device needing a device
specific message size quirk. We are currently unable to support
such a device because using a non default size would break the
implicit userspace API.
The message size is currently a hidden attribute of the cdc-wdm
userspace API. Retrieving it is unnecessarily complex, increasing
the possibility of drivers and applications using different limits.
The resulting errors are hard to debug, and can only be replicated
on identical hardware.
Exporting the maximum message size from the driver simplifies the
task for the userspace application, and creates a unified
information source independent of device and function class. It also
serves to document that the message size is part of the cdc-wdm
userspace API.
This proposed API extension has been presented for the authors of
userspace applications and libraries using the current API: libmbim,
libqmi, uqmi, oFono and ModemManager. The replies were:
Aleksander Morgado:
"We do really need max message size for MBIM; and as you say, it may be
good to have the max message size info also for QMI, so the new ioctl
seems a good addition. So +1 from my side, for what it's worth."
Dan Williams:
"Yeah, +1 here. I'd prefer the sysfs file, but the fact that that
doesn't work for fd passing pretty much kills it."
No negative replies are so far received.

lightnvm: Support for Open-Channel SSDs
Open-channel SSDs are devices that share responsibilities with the host
in order to implement and maintain features that typical SSDs keep
strictly in firmware. These include (i) the Flash Translation Layer
(FTL), (ii) bad block management, and (iii) hardware units such as the
flash controller, the interface controller, and large amounts of flash
chips. In this way, Open-channels SSDs exposes direct access to their
physical flash storage, while keeping a subset of the internal features
of SSDs.
LightNVM is a specification that gives support to Open-channel SSDs
LightNVM allows the host to manage data placement, garbage collection,
and parallelism. Device specific responsibilities such as bad block
management, FTL extensions to support atomic IOs, or metadata
persistence are still handled by the device.
The implementation of LightNVM consists of two parts: core and
(multiple) targets. The core implements functionality shared across
targets. This is initialization, teardown and statistics. The targets
implement the interface that exposes physical flash to user-space
applications. Examples of such targets include key-value store,
object-store, as well as traditional block devices, which can be
application-specific.

rpmsg: Driver for user space endpoint interface
This driver allows rpmsg instances to expose access to rpmsg endpoints
to user space processes. It provides a control interface, allowing
userspace to export endpoints and an endpoint interface for each exposed
endpoint.
The implementation is based on prior art by Texas Instrument, Google,
PetaLogix and was derived from a FreeRTOS performance statistics driver
written by Michal Simek.
The control interface provides a "create endpoint" ioctl, which is fed a
name, source and destination address. The three values are used to
create the endpoint, in a backend-specific way, and a rpmsg endpoint
device is created - with the three parameters are available in sysfs for
udev usage.
E.g. to create an endpoint device for one of the Qualcomm SMD channel
related to DIAG one would issue:
struct rpmsg_endpoint_info info = { "DIAG_CNTL", 0, 0 };
int fd = open("/dev/rpmsg_ctrl0", O_RDWR);
ioctl(fd, RPMSG_CREATE_EPT_IOCTL, &info);
Each created endpoint device shows up as an individual character device
in /dev, allowing permission to be controlled on a per-endpoint basis.
The rpmsg endpoint will be created and destroyed following the opening
and closing of the endpoint device, allowing rpmsg backends to open and
close the physical channel, if supported by the wire protocol.
