When you are happy with a change make it generally available for testing and await feedback. Make a patch available to the relevant maintainer in the list.
Web19 mei 2024 · I presume the sequence you have is next: iio_buffer_refill()-> local_get_buffer()-> device_check_ready()-> poll().When poll() returns 0 (timeout happened, according to man 2 poll), device_check_ready() returns -ETIMEDOUT.So the issue here is that poll() wasn't able to catch some event in kernel, which would lead to correct return. … owncloud kemensosWebThe traditional approach used in IIO to implement buffered capture requires the generation of at least one interrupt per sample. In the interrupt handler the driver reads the sample from the device and copies it to a software buffer. This approach has a rather large per sample overhead associated with it.
