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.

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.

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.

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.
