menuconfig RTIO
bool "RTIO"
if RTIO
config RTIO_EXECUTOR_SIMPLE
bool "A simple executor for RTIO"
default y
help
An simple RTIO executor that will execute a queue of requested I/O
operations as if they are a single chain of submission queue entries. This
does not support concurrent chains or submissions.
config RTIO_EXECUTOR_CONCURRENT
bool "A low cost concurrent executor for RTIO"
default y
help
A low memory cost RTIO executor that will execute a queue of requested I/O
with a fixed amount of concurrency using minimal memory overhead.
config RTIO_SUBMIT_SEM
bool "Use a semaphore when waiting for completions in rtio_submit"
help
When calling rtio_submit a semaphore is available to sleep the calling
thread for each completion queue event until the wait count is met. This
adds a small RAM overhead for a single semaphore. By default wait_for will
use polling on the completion queue with a k_yield() in between iterations.
config RTIO_CONSUME_SEM
bool "Use a semaphore when waiting for completions in rtio_cqe_consume_block"
help
When calling rtio_cqe_consume_block a semaphore is available to sleep the
calling thread for each completion queue event until the wait count is met.
This adds a small RAM overhead for a single semaphore. By default the call
will use polling on the completion queue with a k_yield() in between
iterations.
