Do you mean 'dmadev' ?

Not sure what this sentence means. Better to remove.

You could split this long sentence.

Are we sure we need these details?

There is no API for that, it is internal.
From an user perspective, you need only to list outstanding features
in the release notes.

I don't like having function name in all logs.
I recommend this form of macro:
#define RTE_DMA_LOG(level, ...) \
    rte_log(RTE_LOG_ ## level, rte_dma_logtype, RTE_FMT("dma: " \
        RTE_FMT_HEAD(__VA_ARGS__,) "\n", RTE_FMT_TAIL(__VA_ARGS__,)))

I dislike this macro doing a return. It is hiding stuff.
I know we have it in other classes but I think it is a mistake,
we should avoid macro blocks.

Actually it is looking for an ID,
so it should be dma_find_free_id.

Instead of checking its name, it looks more logical to check the state.

dma_find_by_name?

I don't think this text has value,
and we could imagine allocating a device ata later stage.

You should mention what is the default.
Is the default exported to the app in this file?

What about a function able to do more with the name rte_dma_init?
It should allocate the inter-process shared memory,
and do the lookup in case of secondary process.

Should we add _by_name?
We could have a function to retrieve the ID by devargs as well.

If it is not part of the API, it should not be exposed at all.
Why not having all these stuff in a file dmadev_driver.h?
Is it used by some inline functions?

You cannot say API for drivers, because API means application interface.

OK, sorry there are a lot of comments.
Overrall, that's a good work.
I know you are in holidays, I hope we can finish during next week.
