[dpdk-dev] [PATCH 0/2] remove experimental tag for hotplug API

[Thomas Monjalon]

There are new functions in 18.11 which are fixing some hotplug issues.
OVS would like to use them but do not want to allow experimental
functions.
As these are major functions, fixing some issues, and replacing
a deprecated function, an exception should be done.

[dpdk-dev] [PATCH 1/2] eal: remove experimental tag for probe/remove

[Thomas Monjalon]

The functions rte_dev_probe() and rte_dev_remove() are new
in DPDK 18.11 so they got the experimental tag by policy.
However they are too much basic functions for being skipped
by strict applications which do not use experimental functions.

The alternative is to use rte_eal_hotplug_add() and
rte_eal_hotplug_remove(), but their API requires the application
to parse the devargs string in order to provide bus name,
device name and driver arguments.

The new function rte_dev_probe() is really simpler to use and
more flexible by accepting any devargs string.
Let's encourage applications to use it.

The old functions rte_eal_hotplug_* may be deprecated later.

[dpdk-dev] [PATCH 2/2] ethdev: remove experimental tag for iterator API

[Thomas Monjalon]

After removing the function rte_eth_dev_attach(),
there are two replacement solutions possible:
one using probe event notification, and one using a new iterator.
So the application can get the new probed ports either asynchronously
or synchronously.

The iterator API is new in DPDK 18.11 so they got the experimental
tag by policy. It causes an issue for strict applications which do
not use experimental functions, and want to use the synchronous method.

The replacement for removed API should not be experimental.
That's why the experimental status of the ethdev iterator is removed.

Re: [dpdk-dev] [PATCH 0/2] remove experimental tag for hotplug API

[Thomas Monjalon]

Any comment?

01/11/2018 15:46, Thomas Monjalon:
> There are new functions in 18.11 which are fixing some hotplug issues.
> OVS would like to use them but do not want to allow experimental
> functions.
> As these are major functions, fixing some issues, and replacing
> a deprecated function, an exception should be done.
