Char/Misc and other driver changes for 6.11-rc1
Here is the "big" set of char/misc and other driver subsystem changes for 6.11-rc1. Nothing major in here, just loads of new drivers and updates. Included in here are: - IIO api updates and new drivers added - wait_interruptable_timeout() api cleanups for some drivers - MODULE_DESCRIPTION() additions for loads of drivers - parport out-of-bounds fix - interconnect driver updates and additions - mhi driver updates and additions - w1 driver fixes - binder speedups and fixes - eeprom driver updates - coresight driver updates - counter driver update - new misc driver additions - other minor api updates All of these, EXCEPT for the final Kconfig build fix for 32bit systems, have been in linux-next for a while with no reported issues. The Kconfig fixup went in 29 hours ago, so might have missed the latest linux-next, but was acked by everyone involved.

Description:
|

This read/write attribute allows users to set read-write
|

devices as read-only and back to read-write from userspace.
|

This can be used to unlock and relock write-protection of
|
||||
devices which are generally locked, except during sporadic
|
||||
programming operation.
|
||||
Read returns '0' or '1' for read-write or read-only modes
|
||||
respectively.
|

Write parses one of 'YyTt1NnFf0', or [oO][NnFf] for "on"

Reloading configuration on reset enables an update of the

necessary to power cycle the device to reload the new

configuration bitstream.

4. IIO Interfacing Tools
|
||||
========================
|
||||
|
||||
Linux Kernel Tools
|
||||
------------------
|
||||
|
||||
Linux Kernel provides some userspace tools that can be used to retrieve data
|
||||
from IIO sysfs:
|
||||
|
||||
* lsiio: example application that provides a list of IIO devices and triggers
|
||||
* iio_event_monitor: example application that reads events from an IIO device
|
||||
and prints them
|
||||
* iio_generic_buffer: example application that reads data from buffer
|
||||
* iio_utils: set of APIs, typically used to access sysfs files.
|
||||
|
||||
LibIIO
|
||||
------
|
||||
|
||||
LibIIO is a C/C++ library that provides generic access to IIO devices. The
|
||||
library abstracts the low-level details of the hardware, and provides a simple
|
||||
yet complete programming interface that can be used for advanced projects.
|
||||
|
||||
For more information about LibIIO, please see:
|
||||
https://github.com/analogdevicesinc/libiio
|
||||
See ``Documentation/iio/iio_tools.rst`` for the description of the available IIO
|
||||
interfacing tools.

ADIS16480 driver
|

================
|

|

This driver supports Analog Device's IMUs on SPI bus.
|
||||
|
||||
1. Supported devices
|
||||
====================
|
||||
|
||||
* `ADIS16375 <https://www.analog.com/ADIS16375>`_
|
||||
* `ADIS16480 <https://www.analog.com/ADIS16480>`_
|
||||
* `ADIS16485 <https://www.analog.com/ADIS16485>`_

|
||||
* `ADIS16547 <https://www.analog.com/ADIS16547>`_
|
||||
|
||||
Each supported device is a complete inertial system that includes a triaxial
|
||||
gyroscope and a triaxial accelerometer. Each inertial sensor in device combines
|
||||
with signal conditioning that optimizes dynamic performance. The factory
|
||||
calibration characterizes each sensor for sensitivity, bias, and alignment. As
|
||||
a result, each sensor has its own dynamic compensation formulas that provide
|
||||
accurate sensor measurements.
|
||||
|
||||
2. Device attributes
|
||||
====================
|
||||
|
||||
Accelerometer, gyroscope measurements are always provided. Furthermore, the
|
||||
driver offers the capability to retrieve the delta angle and the delta velocity
|
||||
measurements computed by the device.
|
||||
|
||||
The delta angle measurements represent a calculation of angular displacement
|
||||
between each sample update, while the delta velocity measurements represent a
|
||||
calculation of linear velocity change between each sample update.
|
||||
|
||||
Finally, temperature data are provided which show a coarse measurement of
|
||||
the temperature inside of the IMU device. This data is most useful for
|
||||
monitoring relative changes in the thermal environment.
|
||||
|
||||
ADIS16480 and ADIS16488 also provide access to barometric pressure data and
|
||||
triaxial magnetometer measurements.
|
||||
|
||||
Each IIO device, has a device folder under ``/sys/bus/iio/devices/iio:deviceX``,
|
||||
where X is the IIO index of the device. Under these folders reside a set of
|
||||
device files, depending on the characteristics and features of the hardware
|
||||
device in questions. These files are consistently generalized and documented in
|
||||
the IIO ABI documentation.
|
||||
|
||||
The following tables show the adis16480 related device files, found in the
|
||||
specific device folder path ``/sys/bus/iio/devices/iio:deviceX``.

Channels processed values
|
||||
-------------------------
|
||||
|
||||
A channel value can be read from its _raw attribute. The value returned is the
|
||||
raw value as reported by the devices. To get the processed value of the channel,
|
||||
apply the following formula:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
processed value = (_raw + _offset) * _scale
|
||||
|
||||
Where _offset and _scale are device attributes. If no _offset attribute is
|
||||
present, simply assume its value is 0.
|
||||
|
||||
The adis16480 driver offers data for 7 types of channels, the table below shows
|
||||
the measurement units for the processed value, which are defined by the IIO
|
||||
framework:

3. Device buffers
|
||||
=================
|
||||
|
||||
This driver supports IIO buffers.
|
||||
|
||||
All devices support retrieving the raw acceleration, gyroscope and temperature
|
||||
measurements using buffers.
|
||||
|
||||
The following device families also support retrieving the delta velocity, delta
|
||||
angle and temperature measurements using buffers:
|
||||
|
||||
- ADIS16545
|
||||
- ADIS16547
|
||||
|
||||
However, when retrieving acceleration or gyroscope data using buffers, delta
|
||||
readings will not be available and vice versa. This is because the device only
|
||||
allows to read either acceleration and gyroscope data or delta velocity and
|
||||
delta angle data at a time and switching between these two burst data selection
|
||||
modes is time consuming.
|
||||
|
||||
Usage examples
|
||||
--------------
|
||||
|
||||
Set device trigger in current_trigger, if not already set:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
root:/sys/bus/iio/devices/iio:device0> cat trigger/current_trigger
|
||||
|
||||
root:/sys/bus/iio/devices/iio:device0> echo adis16545-1-dev0 > trigger/current_trigger
|
||||
root:/sys/bus/iio/devices/iio:device0> cat trigger/current_trigger
|
||||
adis16545-1-dev0
|
||||
|
||||
Select channels for buffer read:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
root:/sys/bus/iio/devices/iio:device0> echo 1 > scan_elements/in_deltavelocity_x_en
|
||||
root:/sys/bus/iio/devices/iio:device0> echo 1 > scan_elements/in_deltavelocity_y_en
|
||||
root:/sys/bus/iio/devices/iio:device0> echo 1 > scan_elements/in_deltavelocity_z_en
|
||||
root:/sys/bus/iio/devices/iio:device0> echo 1 > scan_elements/in_temp0_en
|
||||
|
||||
Set the number of samples to be stored in the buffer:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
root:/sys/bus/iio/devices/iio:device0> echo 10 > buffer/length
|
||||
|
||||
Enable buffer readings:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
root:/sys/bus/iio/devices/iio:device0> echo 1 > buffer/enable
|
||||
|
||||
Obtain buffered data::
|
||||
|
||||
root:/sys/bus/iio/devices/iio:device0> hexdump -C /dev/iio\:device0

High-speed DMABUF interface for IIO
|
||||
===================================
|
||||
|
||||
1. Overview
|
||||
===========
|
||||
|
||||
The Industrial I/O subsystem supports access to buffers through a
|
||||
file-based interface, with read() and write() access calls through the
|
||||
IIO device's dev node.
|
||||
|
||||
It additionally supports a DMABUF based interface, where the userspace
|
||||
can attach DMABUF objects (externally created) to an IIO buffer, and
|
||||
subsequently use them for data transfers.
|
||||
|
||||
A userspace application can then use this interface to share DMABUF
|
||||
objects between several interfaces, allowing it to transfer data in a
|
||||
zero-copy fashion, for instance between IIO and the USB stack.
|
||||
|
||||
The userspace application can also memory-map the DMABUF objects, and
|
||||
access the sample data directly. The advantage of doing this vs. the
|
||||
read() interface is that it avoids an extra copy of the data between the
|
||||
kernel and userspace. This is particularly useful for high-speed devices
|
||||
which produce several megabytes or even gigabytes of data per second.
|
||||
It does however increase the userspace-kernelspace synchronization
|
||||
overhead, as the DMA_BUF_SYNC_START and DMA_BUF_SYNC_END IOCTLs have to
|
||||
be used for data integrity.
|
||||
|
||||
2. User API
|
||||
===========
|
||||
|
||||
As part of this interface, three new IOCTLs have been added. These three
|
||||
IOCTLs have to be performed on the IIO buffer's file descriptor, which
|
||||
can be obtained using the IIO_BUFFER_GET_FD_IOCTL() ioctl.
|
||||
|
||||
``IIO_BUFFER_DMABUF_ATTACH_IOCTL(int fd)``
|
||||
Attach the DMABUF object, identified by its file descriptor, to the
|
||||
IIO buffer. Returns zero on success, and a negative errno value on
|
||||
error.
|
||||
|
||||
``IIO_BUFFER_DMABUF_DETACH_IOCTL(int fd)``
|
||||
Detach the given DMABUF object, identified by its file descriptor,
|
||||
from the IIO buffer. Returns zero on success, and a negative errno
|
||||
value on error.
|
||||
|
||||
Note that closing the IIO buffer's file descriptor will
|
||||
automatically detach all previously attached DMABUF objects.
|
||||
|
||||
``IIO_BUFFER_DMABUF_ENQUEUE_IOCTL(struct iio_dmabuf *iio_dmabuf)``
|
||||
Enqueue a previously attached DMABUF object to the buffer queue.
|
||||
Enqueued DMABUFs will be read from (if output buffer) or written to
|
||||
(if input buffer) as long as the buffer is enabled.

IIO Interfacing Tools
|
||||
=====================
|
||||
|
||||
1. Linux Kernel Tools
|
||||
=====================
|
||||
|
||||
Linux Kernel provides some userspace tools that can be used to retrieve data
|
||||
from IIO sysfs:
|
||||
|
||||
* lsiio: example application that provides a list of IIO devices and triggers
|
||||
* iio_event_monitor: example application that reads events from an IIO device
|
||||
and prints them
|
||||
* iio_generic_buffer: example application that reads data from buffer
|
||||
* iio_utils: set of APIs, typically used to access sysfs files.
|
||||
|
||||
2. LibIIO
|
||||
=========
|
||||
|
||||
LibIIO is a C/C++ library that provides generic access to IIO devices. The
|
||||
library abstracts the low-level details of the hardware, and provides a simple
|
||||
yet complete programming interface that can be used for advanced projects.

Marvell CN10K DMA packet interface (DPI) driver
|
||||
===============================================
|
||||
|
||||
Overview
|
||||
========
|
||||
|
||||
DPI is a DMA packet interface hardware block in Marvell's CN10K silicon.
|
||||
DPI hardware comprises a physical function (PF), its virtual functions,
|
||||
mailbox logic, and a set of DMA engines & DMA command queues.
|
||||
|
||||
DPI PF function is an administrative function which services the mailbox
|
||||
requests from its VF functions and provisions DMA engine resources to
|
||||
it's VF functions.
|
||||
|
||||
mrvl_cn10k_dpi.ko misc driver loads on DPI PF device and services the
|
||||
mailbox commands submitted by the VF devices and accordingly initializes
|
||||
the DMA engines and VF device's DMA command queues. Also, driver creates
|
||||
/dev/mrvl-cn10k-dpi node to set DMA engine and PEM (PCIe interface) port
|
||||
attributes like fifo length, molr, mps & mrrs.
|
||||
|
||||
DPI PF driver is just an administrative driver to setup its VF device's
|
||||
queues and provisions the hardware resources, it cannot initiate any
|
||||
DMA operations. Only VF devices are provisioned with DMA capabilities.

||||

|
||||
Driver IOCTLs
|
||||
=============
|
||||
|
||||
:c:macro::`DPI_MPS_MRRS_CFG`
|
||||
ioctl that sets max payload size & max read request size parameters of
|
||||
a pem port to which DMA engines are wired.
|
||||
|
||||
|
||||
:c:macro::`DPI_ENGINE_CFG`
|
||||
ioctl that sets DMA engine's fifo sizes & max outstanding load request
|
||||
thresholds.
|
||||
|
||||
User space code example
|
||||
=======================
|
||||
|
||||
DPI VF devices are probed and accessed from user space applications using
|
||||
vfio-pci driver. Below is a sample dpi dma application to demonstrate on
|
||||
how applications use mailbox and ioctl services from DPI PF kernel driver.
