Note the driver will assume the last p events requested are to be enabled where p is how many it supports (which may vary depending on the exact set requested. So if you want to be sure you have set what you think you have, check the contents of these attributes after everything is configured. Drivers may have to buffer any parameters so that they are consistent when a given event type is enabled at a future point (and not those for whatever event was previously enabled).

Form is [be|le]:[s|u]bits/storagebits[>>shift]. be or le specifies big or little endian. s or u specifies if signed (2's complement) or unsigned. bits is the number of bits of data and storagebits is the space (after padding) that it occupies in the buffer. shift if specified, is the shift that needs to be applied prior to masking out unused bits. Some devices put their data in the middle of the transferred elements with additional information on both sides. Note that some devices will have additional information in the unused bits so to get a clean value, the bits value must be used to mask the buffer output value appropriately. The storagebits value also specifies the data alignment. So s48/64>>2 will be a signed 48 bit integer stored in a 64 bit location aligned to a 64 bit boundary. To obtain the clean value, shift right 2 and apply a mask to zero the top 16 bits of the result. For other storage combinations this attribute will be extended appropriately.

What: /sys/bus/iio/devices/iio:deviceX/buffer/watermark KernelVersion: 4.2 Contact: linux-iio@vger.kernel.org Description: A single positive integer specifying the maximum number of scan elements to wait for. Poll will block until the watermark is reached. Blocking read will wait until the minimum between the requested read amount or the low water mark is available. Non-blocking read will retrieve the available samples from the buffer even if there are less samples then watermark level. This allows the application to block on poll with a timeout and read the available samples after the timeout expires and thus have a maximum delay guarantee. What: /sys/bus/iio/devices/iio:deviceX/buffer/hwfifo_enabled KernelVersion: 4.2 Contact: linux-iio@vger.kernel.org Description: A read-only boolean value that indicates if the hardware fifo is currently enabled or disabled. If the device does not have a hardware fifo this entry is not present. The hardware fifo is enabled when the buffer is enabled if the current hardware fifo watermark level is set and other current device settings allows it (e.g. if a trigger is set that samples data differently that the hardware fifo does then hardware fifo will not enabled). If the hardware fifo is enabled and the level of the hardware fifo reaches the hardware fifo watermark level the device will flush its hardware fifo to the device buffer. Doing a non blocking read on the device when no samples are present in the device buffer will also force a flush. When the hardware fifo is enabled there is no need to use a trigger to use buffer mode since the watermark settings guarantees that the hardware fifo is flushed to the device buffer. What: /sys/bus/iio/devices/iio:deviceX/buffer/hwfifo_watermark KernelVersion: 4.2 Contact: linux-iio@vger.kernel.org Description: Read-only entry that contains a single integer specifying the current watermark level for the hardware fifo. If the device does not have a hardware fifo this entry is not present. The watermark level for the hardware fifo is set by the driver based on the value set by the user in buffer/watermark but taking into account hardware limitations (e.g. most hardware buffers are limited to 32-64 samples, some hardware buffers watermarks are fixed or have minimum levels). A value of 0 means that the hardware watermark is unset. What: /sys/bus/iio/devices/iio:deviceX/buffer/hwfifo_watermark_min KernelVersion: 4.2 Contact: linux-iio@vger.kernel.org Description: A single positive integer specifying the minimum watermark level for the hardware fifo of this device. If the device does not have a hardware fifo this entry is not present. If the user sets buffer/watermark to a value less than this one, then the hardware watermark will remain unset. What: /sys/bus/iio/devices/iio:deviceX/buffer/hwfifo_watermark_max KernelVersion: 4.2 Contact: linux-iio@vger.kernel.org Description: A single positive integer specifying the maximum watermark level for the hardware fifo of this device. If the device does not have a hardware fifo this entry is not present. If the user sets buffer/watermark to a value greater than this one, then the hardware watermark will be capped at this value. What: /sys/bus/iio/devices/iio:deviceX/buffer/hwfifo_watermark_available KernelVersion: 4.2 Contact: linux-iio@vger.kernel.org Description: A list of positive integers specifying the available watermark levels for the hardware fifo. This entry is optional and if it is not present it means that all the values between hwfifo_watermark_min and hwfifo_watermark_max are supported. If the user sets buffer/watermark to a value greater than hwfifo_watermak_min but not equal to any of the values in this list, the driver will chose an appropriate value for the hardware fifo watermark level.
