From: Tony Nguyen <anthony.l.nguyen@intel.com>
The RDMA block does not advertise on the PCI bus or any other bus.
Thus the ice driver needs to provide access to the RDMA hardware block
via a virtual bus; utilize a multi-function device to provide this access.
This patch initializes the driver to support RDMA as well as creates
and registers a multi-function device for the RDMA driver to register to.
At this point the driver is fully initialized to register a platform
driver, however, can not yet register as the ops have not been
implemented.
We refer to the interaction of this platform device as Inter-Driver
Communication (IDC); where the platform device is referred to as the peer
device and the platform driver is referred to as the peer driver.
Note that the header file iidc.h has been located under
include/linux/net/intel as this file is a unified header file to be used by
the ice and irdma driver.

Again, no platform devices, unless it REALLY IS a platform device (i.e.
you are using device tree or platform data to find it.) Is that what
you are doing here?

The RDMA block does not have its own PCI function so it must register
and interact with the ice driver.

Sorry, this was an oversight. When I was changing the wording in the
commit message away from platform device, I missed this one.
I will rewrite the commit message to make things clearer and correct
the platform device reference.

So the "ice driver" is the real thing controlling the pci device? How
does it "know" about the RDMA block?

The ICE driver loads and registers to control the PCI device. It then
creates an MFD device with the name 'ice_rdma'. The device data provided to
the MFD subsystem by the ICE driver is the struct iidc_peer_dev which
contains all of the relevant information that the IRDMA peer will need
to access this PF's IIDC API callbacks
The IRDMA driver loads as a software only driver, and then registers a MFD
function driver that takes ownership of MFD devices named 'ice_rdma'.
This causes the platform bus to perform a matching between ICE's MFD device
and IRDMA's driver. Then the patform bus will call the IRDMA's IIDC probe
function. This probe provides the device data to IRDMA.

This was the last communication that I saw on this topic. I was taking Greg's silence as
"Oh ok, that works" :) I hope I was not being too optimistic!
If there is any outstanding issue I am not aware of it, but please let me know if I am
out of the loop!
Greg, if you have any other concerns or questions I would be happy to address them!

I was hoping to hear Greg say that taking a pci_device, feeding it to
the multi-function-device stuff to split it to a bunch of
platform_device's is OK, or that mfd should be changed somehow..
As far I as I was interested in the, the basic high level approach
seems much better than the previous attempt using net notifiers.

Again, platform devices are ONLY for actual platform devices. A PCI
device is NOT a platform device, sorry.
If MFD needs to be changed to handle non-platform devices, fine, but
maybe what you really need to do here is make your own "bus" of
individual devices and have drivers for them, as you can't have a
"normal" PCI driver for these.
Again, please stop abusing platform devices.

To be fair to David, IIRC, you did suggest mfd as the solution here
some months ago, but I think you also said it might need some fixing
:)

It does feel like MFD is the cleaner model here otherwise we'd have
each driver making its own custom buses for its multi-function
capability..
David, do you see some path to fix mfd to not use platform devices?
Maybe it needs a MFD bus type and a 'struct mfd_device' ?
I guess I'll drop these patches until it is sorted.

The original submission of the RDMA driver had separate drivers to
interact with the ice and i40e LAN drivers. There was only about 2000
lines of code different between them, so a request was (rightly so)
made to unify the RDMA drivers into a single driver.
Our original submission for IIDC had a "software bus" that the ice driver
was creating. The problem, now that the RDMA driver is a unified driver
for both the ice and i40e drivers, each of which would need to create their
own bus. So, we cannot have module dependencies for the irdma driver,
as we don't know which hardware the user will have installed in the system.
or which drivers will be loaded in what order. As new hardware is supported
(presumably by the same irdma driver) this will only get more complicated.
For instance, if the ice driver loads, then the irdma, then the i40e. The irdma
will have no notice that a new bus was created that it needs to register with
by the i40e driver.
Our original solution to this problem was with netdev notifiers, which met with
resistance, and the statement that the bus infrastructure was the proper way to
approach the interaction of the LAN driver and peer. This did turn out to be a
much more elegant way to approach the issue.
The direct access of the platform bus was unacceptable, and the MFD sub-system
was suggested by Greg as the solution. The MFD sub-system uses the platform
bus in the background as a base to perform its functions, since it is a purely software
construct that is handy and fulfills its needs. The question then is: If the MFD sub-
system is using the platform bus for all of its background functionality, is the platform
bus really only for platform devices? It seems that the kernel is already using the
platform bus as a generic software based bus, and it fulfills the role efficiently.

Yes, how many times do I have to keep saying this?
The platform bus should ONLY be used for devices that are actually
platform devices and can not be discovered any other way and are not on
any other type of bus.
If you try to add platform devices for a PCI device, I am going to
continue to complain. I keep saying this and am getting tired.
Now yes, MFD does do "fun" things here, and that should probably be
fixed up one of these days. But I still don't see why a real bus would
not work for you.

I'm sorry, the last thing I want to do is to annoy you! I just need to
figure out where to go from here. Please, don't take anything I say as
argumentative.
I don't understand what you mean by "a real bus". The irdma driver does
not have access to any physical bus. It utilizes resources provided by
the PCI LAN drivers, but to receive those resources it needs a mechanism
to "hook up" with the PCI drivers. The only way it has to locate them
is to register a driver function with a software based bus of some kind
and have the bus match it up to a compatible entity to achieve that hook up.
The PCI LAN driver has a function that controls the PCI hardware, and then
we want to present an entity for the RDMA driver to connect to.
To move forward, we are thinking of the following design proposal:
We could add a new module to the kernel named generic_bus.ko. This would
create a new generic software bus and a set of APIs that would allow for
adding and removing simple generic virtual devices and drivers, not as
a MFD cell or a platform device. The power management events would also
be handled by the generic_bus infrastructure (suspend, resume, shutdown).
We would use this for matching up by having the irdma driver register
with this generic bus and hook to virtual devices that were added from
different PCI LAN drivers.
Pros:
1) This would avoid us attaching anything to the platform bus
2) Avoid having each PCI LAN driver creating its own software bus
3) Provide a common matching ground for generic devices and drivers that
eliminates problems caused by load order (all dependent on generic_bus.ko)
4) Usable by any other entity that wants a lightweight matching system
or information exchange mechanism
Cons:
1) Duplicates part of the platform bus functionality
2) Adds a new software bus to the kernel architecture
Is this path forward acceptable?
Thanks for any clarification/guidance you can provide!

Yes, that is much better. But how about calling it a "virtual bus"?
It's not really virtualization, but we already have virtual devices
today when you look in sysfs for devices that are created that are not
associated with any specific bus. So this could take those over quite
nicely! Look at how /sys/devices/virtual/ works for specifics, you
could create a new virtual bus of a specific "name" and then add devices
to that bus directly.

If I'm not mistaken, currently the virtual devices do not have a parent and
may not have a bus so there is no enumeration and hence binding to a driver.
This is not a case here, as the parent is the PCI device, and we need
to bind to a driver.
Code-wise the platform bus contains all the functionality needed by
such virtual bus, for example helpers for the adding of resources that
are inherited
from its parent PCI device,
MMIO and IRQ, the issue is just the name of the bus and associated sysfs?
In that case the platform bus will be a special case of the virtual bus?
Thanks

From: Mustafa Ismail <mustafa.ismail@intel.com>
Register multi-function devices (MFD) for the RDMA platform
function (irdma) driver to bind to. It realizes a single RDMA
driver capable of working with multiple LAN drivers over
multi-generation Intel HW supporting RDMA. There is also no load
ordering dependencies between i40e and irdma.
Summary of changes:
* Support to add/remove MFD devices
* Add 2 new client ops.
* i40e_client_device_register() which is called during RDMA
probe() per PF. Validate client drv OPs and schedule service
task to call open()
* i40e_client_device_unregister() called during RDMA remove()
per PF. Call client close() and release_qvlist.
* The global register/unregister calls exported for i40iw are retained
until i40iw is removed from the kernel.

I thought Greg already said not to use platform_device for this?

Yes I did, which is what I thought this whole "use MFD" was supposed to
solve. Why is a platform device still being used here?

Looks like when mfd creates the 'multi' devices it creates them as
platform_devices
/*
* Given a platform device that's been created by mfd_add_devices(), fetch
* the mfd_cell that created it.
*/
static inline const struct mfd_cell *mfd_get_cell(struct platform_device *pdev)

That's right. We used the MFD framework. mfd_add_devices() registers the child devices
as platform devs. And the function drivers probe() will get a platform dev.

Changing parameters through workqueue and perform locking with atomic_t, exciting.
Please do proper locking scheme and better to avoid workqueue at all.

This is can't be in upstream code, we don't support out-of-tree modules,
everything else will have proper versions.

Hmmm....Yes, this is buggy. Will come up with a better solution.

Who is the "we" in this context? I am sure that all the Linux
distributions would strongly disagree with this stance. Whether or not
you support out-of-tree drivers, they do exist and this code would
ensure that if a "out-of-tree" driver is loaded, the driver will do a
sanity check to ensure the RDMA driver will work.

Upstream sensibility - if we start doing stuff like this then we will

I don't see how this is any different from any of the other myriad of
problems out of tree modules face.
Someone providing out of tree modules has to provide enough parts of
their driver so that it only consumes the stable ABI from the distro
kernel.
Pretty normal stuff really.

I see you cut out the part of my response about Linux distributions

Your right, if the dependency was reversed and the out-of-tree (OOT) driver
was dependent upon the RDMA driver, but in this case it is not. The LAN
driver does not "need" the RDMA driver to work. So the RDMA driver should
at least check that the LAN driver loaded has the required version to work.
This line of thinking, "marries" the in-kernel RDMA driver with the in-
kernel LAN driver(s) so the end users and Linux distro's can not choose to
upgrade or use any other driver than what comes with the kernel. I totally
agree that any out-of-tree (OOT) driver needs to make sure they have all
kernel ABI's figured out for whatever kernel they are being installed on.
But what is the problem with the in-kernel RDMA driver to do it's own
checks to ensure the driver it is dependent upon meets its minimum
requirements?
Similar checks are done in the Intel LAN driver to ensure the firmware is
of a certain level, which is no different than what is being done here.

Not in upstream code, there is an expectation that kernel and modules are aligned.

It is packaging problem to ensure that those minimum requirements are in
place.

It doesn't say that it is correct way of doing things. FW is not part
of the kernel hence needs to be checked. Modules are different from
FW because they are part of the distributed kernel.

s/expectation/requirement/
If you do not do that, all bets are off.
Distros can decide to do whatever they want with their kernels, but
that's not what we require upstream.

Sure, this is an upstream decision.. I think everyone knows distros

So? IMHO you have to provide both drivers if you want to have an OOT
solution as the lan driver is providing and changing kABI outside the
distro promise of kABI stability.
It is no different than replacing, say, the entire core RDMA subsystem as
many people tend to do.

Yes, but upgrade is possible, you have to provide both.

It is against the upstream policy and we'd have a proliferation of
these checks if it was allowed, IMHO.

External dependencies are expected to check compatability.

From: Mustafa Ismail <mustafa.ismail@intel.com>
The driver posts privileged commands to the HW
Admin Queue (Control QP or CQP) to request administrative
actions from the HW. Implement create/destroy of CQP
and the supporting functions, data structures and headers
to handle the different CQP commands

From: Mustafa Ismail <mustafa.ismail@intel.com>
HW uses host memory as a backing store for a number of
protocol context objects and queue state tracking.
The Host Memory Cache (HMC) is a component responsible for
managing these objects stored in host memory.
Add the functions and data structures to manage the allocation
of backing pages used by the HMC for the various objects

From: Jeff Kirsher @ 2019-09-26 16:45 UTC (permalink / raw)
To: dledford, jgg, gregkh; +Cc: Mustafa Ismail, netdev, linux-rdma, Shiraz Saleem
From: Mustafa Ismail <mustafa.ismail@intel.com>
Add definitions for managing the RDMA HW work scheduler (WS) tree.
A WS node is created via a control QP operation with the bandwidth
allocation, arbitration scheme, and traffic class of the QP specified.
The Qset handle returned associates the QoS parameters for the QP.
The Qset is registered with the LAN and a equivalent node is created
in the LAN packet scheduler tree.

I'm talking about kqp.wrid_mem you allocated a couple of lines above and
didn't free in case of sq_wrtrk_array allocation failed.

Can you simply delete old one and add MODULE_ALIAS() in new driver?

Yes, but we thought typically driver has to be deprecated for a few cycles before removing it.

If you completely replace it with something that works the same, why
keep the old one around at all?
Unless you don't trust your new code? :)

I have yet to see, in over 20 years of kernel experience, a new driver
replace an old driver and not initially be more buggy and troublesome
than the old driver. It takes time and real world usage for the final
issues to get sorted out. During that time, the fallback is often
necessary for those real world users.

How many real users exist in RDMA world who run pure upstream kernel?

I doubt too many especially the latest bleeding edge upstream kernel.
That could be interesting, but I don't think it's the reality.
Distro kernels could certainly still keep the old driver, and that makes
a lot of sense.

Also, they are invited to run their regression suite to verify
stability and report any arising problems to upstream/vendor.

Hi Jeff,
Can this be fetched from somewhere? didn't see a related branch at

I can make these patches available, I had not pushed them to my tree
because they were RFC.
I will push these series of patches to the "rdma" branch of my next-
queue git tree on kernel.org.
