This series adds support for the rotation sensor functionality present in
some chips from the ST LSM6DSX IMU family.
The IIO ABI has been amended to allow the use of floating-point data and
custom (driver-specific) channels in IIO buffers.
Tested on LSM6DSV16X.
Changes from v5 [5]:
- cleaned up FIFO data representation in st_lsm6dsx_read_tagged_fifo() to
avoid casting (Andy, Jonathan)
- renamed 'sign' field to `format` in struct iio_scan_type
- added support for IEEE 754 floating-point format in buffer scan elements
- added custom data type in the ABI (IIO_CUSTOM in enum iio_chan_type)
(Jonathan)
- added driver document in Documentation/iio/ (Jonathan)
Changes from v4 [4]:
- changed data parameter in st_lsm6dsx_push_tagged_data() to __le16 *
(Andy)
Changes from v3 [3]:
- added patch 3 (Andy)
- removed unneeded checks for negative return values in st_lsm6dsx_fusion.c
(Andy)
- replaced st_lsm6dsx_sf_set_page function with
st_lsm6dsx_sf_page_enable/disable (Andy)
- used reversed xmas tree ordering for local variables (Andy)
- added parentheses to MILLI / MICRO in st_lsm6dsx_sf_write_raw (Andy)
- added check for string truncation in st_lsm6dsx_sf_probe (Andy)
Changes from v2 [2]:
- amended description of patch 2 to point out that there are no supported
gyro events (Jonathan)
- removed superfluous parentheses in st_lsm6dsx_fifo_setup (Lorenzo)
- added Lorenzo's acked-by tag to patch 3
- added missing checks of st_lsm6dsx_sf_set_page() return value (Jonathan)
- added comment in st_lsm6dsx_sf_write_raw (Jonathan)
Changes from v1 [1]:
- swapped patches 1 and 2 (Jonathan)
- miscellaneous stylistic changes (Andy)
- fixed usage of MICRO and MILLI constants in st_lsm6dsx_sf_read_raw and
st_lsm6dsx_sf_write_raw (Andy)
- replaced scnprintf() with sysfs_emit_at() in
st_lsm6dsx_sf_sampling_freq_avail (Andy)
- replaced scnprintf() with snprintf() in st_lsm6dsx_sf_probe (Andy)
- clarified in a comment in st_lsm6dsx_set_fifo_odr() that only internal
sensors have a FIFO ODR configuration register (Jonathan)
- modified patch 3 description to explain justification for the extra IIO
device (Jonathan)
- moved page lock from st_lsm6dsx_sf_set_page() to the callers (Jonathan)
- s/magnetometer/gyroscope/ in patch 2 description

This logic is valid for internal sensors only, i.e. the accelerometer and gyroscope; however, since commit c91c1c844ebd ("iio: imu: st_lsm6dsx: add i2c embedded controller support"), this function is called also when configuring the hardware FIFO for external sensors (i.e. sensors accessed through the sensor hub functionality), which can result in unrelated device registers being written.

The motivation for being able to set a buffer frequency different from the sensor sampling frequency is to support use cases that need accurate event detection (which requires a high sampling frequency) while retrieving sensor data at low frequency. Since all the supported event types are generated from acceleration data only, do not create the buffer sampling frequency attribute for sensor types other than the accelerometer.

The driver checks FIFO samples against these special values in order to discard invalid samples; however, it does the check regardless of the type of samples being processed, whereas this feature is specific to gyroscope and accelerometer data. This could cause valid samples to be discarded. Fix the above check so that it takes into account the type of samples being processed. To avoid casting to __le16 * when checking sample values, clean up the type representation for data read from the FIFO.

One of these features generates rotation vector data and makes it available in the hardware FIFO as a quaternion (more specifically, the X, Y and Z components of the quaternion vector, expressed as 16-bit half-precision floating-point numbers). Add support for a new sensor instance that allows receiving sensor fusion data, by defining a new struct st_lsm6dsx_sf_settings (which contains chip-specific details for the sensor fusion functionality), and adding this struct as a new field in struct st_lsm6dsx_settings. In st_lsm6dsx_core.c, populate this new struct for the LSM6DSV and LSM6DSV16X chips, and add the logic to initialize an additional IIO device if this struct is populated for the hardware type being probed. Note: a new IIO device is being defined (as opposed to adding channels to an existing device) because the rate at which sensor fusion data is generated may not match the data rate from any of the existing devices. Tested on LSMDSV16X.

This logic is valid for internal sensors only, i.e. the accelerometer and gyroscope; however, since commit c91c1c844ebd ("iio: imu: st_lsm6dsx: add i2c embedded controller support"), this function is called also when configuring the hardware FIFO for external sensors (i.e. sensors accessed through the sensor hub functionality), which can result in unrelated device registers being written.

The driver checks FIFO samples against these special values in order to discard invalid samples; however, it does the check regardless of the type of samples being processed, whereas this feature is specific to gyroscope and accelerometer data.

In current code it's 64-bit and not 48-bit item. Fortunately, the layout of a structure does not change because the first member could be stored at a less-aligned address, as that would make it incompatible with a different instance that is stored at a differently-aligned address ;-) The alignment of a structure is the maximum of the alignments of its members. So that will be 8 bytes, as the aligned_s64 definition has an internal "__attribute__((aligned(8)))". It would be wise to add explicit padding ("u16 pad") just before timestamp though, for documentation purpose.

We typically haven't done this. I'm not sure why this driver justifies it as IIO timestamp placement always relies on the set of rules Geert has laid out. Also if we did do it, applying an endianness to reserve data is a an odd thing to do. So as far a I'm concerned the approach in this patch seems fine.

Please do the union for v7. Not so much because I mind a global change, but more because the chances of merge conflicts are too high. Perhaps for this series just introduce the union and use it in the driver here. We can then chase it through the rest of the tree as a separate step. Alternatively leave it with a misleading name for now (so allow 'f' to be a magic sign value) and we can do the rename as a follow up.

For this patch series, could we still use IIO_ROT and introduce a new IIO_MOD_PARTIAL_QUATERNION that is defined according to the description in the documentation patch in this series? This may be the only driver that ever uses it, but it is still clearly defined.

Another option could be having a custom iio_modifier instead of a custom iio_chan_type. I think this would address the concern of drivers being just a proxy between hardware and userspace. A custom modifier would be used when the data representation for a given channel is too exotic to warrant a generic iio_modifier enum value (but would still need to be documented so that userspace can make use of it). I can imagine a generic userspace application that interfaces with (in this case) rotation sensors (i.e. looks for IIO_ROT channels) and can support not only "standard" rotation data types (yaw, pitch, roll, quaternion, etc) but also "manufacturer-specific" types. We could even think about allowing more than one custom modifier (e.g. everything >= IIO_MOD_CUSTOM is a custom modifier) so that a sensor can have its "manufacturer-specific" data in multiple separate channels; and of course each such custom modifier would have to be described in a per-driver doc. ^ permalink raw reply [flat|nested] 32+ messages in thread

And I am against this. It will provoke a vendor to escape the standards, common libraries and other tools. If we need something which is too exotic, the driver should convert it to the standard one. This way we will support HW and won't require or allow some dirty tricks based on vendor-locked approaches. I'm talking from the experience on what vendors are doing or want to do IRL in other areas. One of the infamous example, is Broadcom Bluetooth used back in Nokia phones, the so called "driver" is useless completely in the kernel as it's just a proxy for the HW <--> userspace link. TL;DR: I'm in favour for anything that does not touch user space at all, or has explicit meanings.

NAK for CUSTOM, manufactirer-specific, et cetera > from me is warranted. The representation here is to my mind 'odd' enough that I'm be surprised if another manufacturer ever used it. Maybe I'm wrong though, I'm out of touch with IMUs these days and defacto standards do arise sometimes. I'm not sure we can paper over it in the kernel without going to floating point maths and I don't want to start a precedence for doing that. If anyone can figure out an efficient integer solution, then that would be great. I'm not against a specific modifier, but that space is only so big so I don't want to end up running out of space. Maybe this is a case for a low impact experiment: We add a specific modifier for this format - with full documentation (and userspace code in the tools that come with the kernel) and see if that opens the flood gates to requests for other custom channels. It's worth noting I was relaxed on this once before for pulse oximeters (the things under drivers/iio/health) because for various odd historical reasons I happened to know a bit about the maths needed to get data from those and there was a plausible channel type for the channels (as they were always light sensing, be it against a light source that was varying). That one didn't lead to a deluge but then it was more a case of allowing a minor abuse of the ABI than adding an official custom path. Also worth noting this sensor provides all of the real channels in normal ABI compliant fashion, it's just this odd derived channel that is tripping us up.

One of these features generates rotation vector data and makes it available in the hardware FIFO as a quaternion (more specifically, the X, Y and Z components of the quaternion vector, expressed as 16-bit half-precision floating-point numbers). Add support for a new sensor instance that allows receiving sensor fusion data, by defining a new struct st_lsm6dsx_sf_settings (which contains chip-specific details for the sensor fusion functionality), and adding this struct as a new field in struct st_lsm6dsx_settings. In st_lsm6dsx_core.c, populate this new struct for the LSM6DSV and LSM6DSV16X chips, and add the logic to initialize an additional IIO device if this struct is populated for the hardware type being probed. Note: a new IIO device is being defined (as opposed to adding channels to an existing device) because the rate at which sensor fusion data is generated may not match the data rate from any of the existing devices.
