Split rte_eth_dev structure to two parts: head that is available for
user applications, and rest which is DPDK internal.
Make an array of pointers to rte_eth_dev structures available for user
applications.

This is in the library, not sure if libraries should include the header file for
the drivers, can you please explain why this change is needed?

I was hoping "rte_ethdev_core.h" can be removed completely by distributing its
content to "ethdev_private.h", "rte_ethdev_driver.h" and perhaps even to
"rte_ethdev.h".

Can you please explain what prevents removing "rte_ethdev_core.h"?

Casts are error prone. Is it possible to use container_of instead of direct cast.

It is needed to make rte_eth_dev structure available. But yes, I agree that it will be more appropriate to include rte_ethdev.h and rte_ethdev_core.h separately. I probably wanted less includes, silly me.

I could rename it to rte_ethdev_private. There is just rte_eth_dev and rte_eth_dev_data left in it.

I could if I had a pointer to struct rte_eth_dev_functions and needed to get struct rte_eth_dev which is a container structure in this case. But I could use offsetof instead.

I think drivers access to both 'rte_eth_dev' and 'rte_eth_dev_data' so can't
move them to 'ethdev_private.h' why not move it to 'rte_ethdev_driver.h'?

Because the libraries use them as well.

These are 'librte_ethdev' library internal data, I think other libraries
shouldn't access them directly.

As far as I can see,
librte_eventdev  => rte_eth_dev_data
librte_eventdev  => rte_eth_dev
librte_telemetry => rte_eth_dev

Can you see any other library accessing 'rte_eth_dev' and 'rte_eth_dev_data' ?


I am not sure about 'eventdev', specially because of the Rx/Tx adapters of it,
perhaps they can include the "rte_ethdev_driver.h", cc'ed Jerin.

I didn't check the telemetry code, but I assume it can be fixed too, but for now
"rte_ethdev_driver.h" can be included to highlight something is wrong there.

And related "ethdev_private.h", as far as I understand it is not private to all
libraries, it is private to the ethdev library, which means only should be used
to share the definitions withing ethdev library .c files. So no other library
should include it.

I would like to raise one more concern (maybe not the smartest thing to do
involving my own patch, but I will sleep better when this is resolved).
Does anyone know what the author of this comment had in mind? I could not find
any code that utilizes this split, and this patch clearly breaks it. If it is
obsolete, I guess this comment could be removed.

As the comment suggest the split is for multi-process suport. The data
structures for the RX/TX queues etc. all need to be common across
processes, while the function pointers need to be per-process. Originally,
in very early versions of DPDK there was no rte_eth_dev_data structure, all
fields - both data and function pointers - were in rte_eth_dev itself.

Yes, I see the need to have the elements separated. But the comment suggests
that the order of variables in structure is important. I just want to make
sure that it is not.

I don't believe it's particularly significant. The main thing was to ensure
that we kept the fast-path accessed data on the same cacheline.

Yes.

Overall this patch theme looks good to me. I will wait for v3 to
change PMDs I maintains.

My only comment is, We should make rte_ethdev_driver.h as private
i.e it should not be included by applications.

Currently. On dpdk install, the private header file is copied to prefix

ie

make install T=x86_64-native-linux-gcc DESTDIR=install

[master][dpdk.org] $ ls install/include/dpdk/rte_ethdev_driver.h
install/include/dpdk/rte_ethdev_driver.h

The internal libraries can access the header file through the
following scheme without exposing it as public.

CFLAGS += -I$(RTE_SDK)/lib/librte_ethdev/

in .c file

#include "ethdev_driver.h"
