iio: nvi: fix timestamps 2017-07-13T21:12:49+00:00 Erik Lilliebjerg elilliebjerg@nvidia.com 2015-04-29T09:08:18+00:00 b8b96d38078be6cb55a453a366a20f161d7f9bba - The previous version of the INV driver used a timestamp FIFO that the interrupt handler added a timestamp to on each interrupt. The waking thread pulled those timestamps and applied them to the data pulled from the data FIFO using a best-fit algorithm. Although the algorithm worked pretty well, there were some loose ends in the mechanism where a local timestamp was used in places when the FIFO was disabled, for example, in low power mode, and wasn't synced with the FIFO timestamps, causing hiccups where timestamps went back in time. There were also issues of lost interrupts and too many interrupts since the interrupts are disabled at times. This version addresses these issues by removing the timestamp FIFO altogether, although the last timestamp is always stored to sync to. Already knowing when the sensor is enabled or the last timestamp used and at what rate the sensor provides data, the timestamp algorithm is much simpler by simply dividing the difference in time between data pulled now and since last pulled by the number of data samples. Obviously there is a little more to this but basically it works backwards with the known "now time" ensuring that timestamps never go back further than the previous one used. - The main reason for the timestamp rewrite rather than fixing the trivial bugs in the previous version is that the timestamp FIFO mechanism won't work on the ICM part when in multiple FIFO mode since each FIFO can run at a separate rate causing inconsistent correlation between FIFO timestamps and the data pulled in each FIFO. This timestamp algorithm allows us to move to a separate FIFO per sensor.
