This set of patches generalize the ethernet device model sufficently
to support virtual, pci, and vmbus devices.
All this is based on the XP principal of only building what is
necessary and no more than that. The rationale is NOT to rework the
DPDK to have same level of bus and parent information as the Linux
device model. This would be unnecessary, fragile and unnecessarily OS
dependent.
Instead, this set of patches does the simple change of refactoring
so that the object relationship between ethernet (rte_eth_dev),
PCI (rte_pci_device) and generic (rte_device) is properly broken
apart.
It does make the simplifying assumption that the device driver knows
what type of bus it is on. For a future case where a device has to
be able to handle different bus families; then the device driver
can have multiple device drivers in one code base (like ixgbe PF/VF).
Jan Blunck (1):
eal: define container_of macro
Stephen Hemminger (12):
ethdev: increase length ethernet device internal name
rte_device: make driver pointer const
eal: introduce driver type
pmd: remove useless reset of dev_info->dev_pci
ethdev: make dev_info generic (not just PCI)
e1000: localize mapping from eth_dev to pci
ixgbe: localize mapping from eth_dev to pci_device
i40e: localize mapping of eth_dev to pci
virtio: localize mapping from rte_eth to pci
broadcom: localize mapping from eth_dev to pci
ethdev: change pci_dev to generic device
hyperv: VMBUS support infrastucture

Since rte_eth_dev_info_get does memset() on dev_info before
calling device specific code, the explicit assignment of NULL
in all these virtual drivers has no effect.

The result from rte_eth_dev_info_get should have pointer to
device not PCI device. This breaks ABI but is necessary.

To: dev; +Cc: Stephen Hemminger
Create one macro for where PCI device information is extracted
from ethernet device. Makes later changes easier to review, and test.

From: Stephen Hemminger @ 2016-12-19 21:59 UTC (permalink / raw)
To: dev; +Cc: Stephen Hemminger
Since later changes will change where PCI information is,
localize mapping in one macro.

From: Stephen Hemminger @ 2016-12-19 21:59 UTC (permalink / raw)
To: dev; +Cc: Stephen Hemminger
Use one function to get mapping from rte_eth_dev to pci_device.
Safely handle some possible misconfiguration of virtio_user related
to link state interrupt.

To: dev; +Cc: Stephen Hemminger
Generalize existing bus support to handle VMBUS in Hyper-V.
Most of the code is based of existing model for PCI, the difference
is how bus is represented in sysfs and how addressing works.
This is based on earlier code contributed by Brocade.

Just to clarify my doubt: UUID is 36 byte long. So, 4 extra bytes are to
keep the name length 4 byte aligned (along with one byte of \0)?
Or, PCI based addressing can stretch 40 bytes?

So the expectation is that if a new device type is introduced (anything
other than virtual or PCI), this enum is expanded?
Broadly, we have two possible ways being discussed on ML for device
relationship with PMD/APIs:
1. the way you have done: each device belongs to a particular type (enum
rte_driver_type) and based on its type, operations would be performed on
it (using conditional operators, for example). We continue to have a
common device list containing all type of devices.
2. disassociating the device (rte_device) completely from its type and
basing it on a Bus type. So, we have separate buses for each device type
and hence no need for separation of logic based on device type.
I think implementation similar to (1) existed before it was removed in
6751f6de.
I have an (obvious) inclination towards (2) because that helps plugging
in more drivers/device types without expecting the contributor to change
the EAL - however trivial the change is.

I don't think that exposing the device through dev_info makes this a
future proof. If we want to model some kind of extensions to dev_info
we should instead model this explicitly.
So from my point of view the pci_dev should get removed instead.

Yes, as I pointed out when reviewing the bus related changes the
refactoring of the ethdev doesn't depend on the bus work to get merged
first.
I've sent a similar series in November already. I guess that is a sign
that the review got stuck somewhere.

I wonder who is the user of the type. It can't be the driver itself
because it must be aware of what kind of low-level interface it
serves. So this seems to be a helper to allow users of rte_driver to
upcast to the object that embeds the rte_driver at runtime. I don't
believe that this is a good interface because it often leads to ugly
and error prone code.

There were types in v16.07 and previous.
Types has been removed in v16.11.
Now are we sure we want to add them back?

The thing I ran into was the test code. The testpmd (and related code) is an
example of how some code might want to use dev_info_get to find out about a device
then take some action based on the driver type. Testpmd has code that manipulates
PCI registers. Right now it is broken when run on virtual devices.

UUID needs 37 bytes (36 + \0).
I just rounded up to next 4 byte boundary since it seemed like a good idea expecting
that it might have to grow later.
Alternatively we could just get rid of NAME_MAX_LEN and allow arbitrary length...

It is more about providing feedback to applications in info_get which is
the only place they should care.

The difference is that virtual devices don't actually live on bus.
So it is really a property of the device not a bus per say.
