From: Dave Ertman <david.m.ertman@intel.com>
This is the initial implementation of the virtual bus,
virtbus_device and virtbus_driver. The virtual bus is
a software based bus intended to support registering
virtbus_devices and virtbus_drivers and provide matching
between them and probing of the registered drivers.
The primary purpose of the virtual bus is to provide
matching services to allow the use of a container_of
to get access to a piece of desired data. This will
allow two separate kernel objects to match up and
start communication.
The bus will support probe/remove shutdown and
suspend/resume callbacks.
Kconfig and Makefile alterations are included

+===============================
+Virtual Bus Devices and Drivers
+===============================
+
+See <linux/virtual_bus.h> for the models for virtbus_device and virtbus_driver.
+This bus is meant to be a lightweight software based bus to attach generic
+devices and drivers to so that a chunk of data can be passed between them.
+
+One use case example is an rdma driver needing to connect with several
+different types of PCI LAN devices to be able to request resources from
+them (queue sets). Each LAN driver that supports rdma will register a
+virtbus_device on the virtual bus for each physical function. The rdma
+driver will register as a virtbus_driver on the virtual bus to be
+matched up with multiple virtbus_devices and receive a pointer to a
+struct containing the callbacks that the PCI LAN drivers support for
+registering with them.
+
+Sections in this document:
+ Virtbus devices

+ Device naming and driver binding
+ Virtual Bus API entry points
+
+Virtbus devices
+~~~~~~~~~~~~~~~
+Virtbus_devices are lightweight objects that support the minimal device
+functionality. Devices will accept a name, and then an automatically
+generated index is concatenated onto it for the virtbus_device->name.
+
+The virtbus_driver and virtbus_device creators need to both have access
+to a predefined virtbus_device_object struct that will look like the
+following:
+ struct virtbus_object {
+ struct virtbus_device vdev;
+ struct foo_type foo;
+ }
+
+Then when the virtbus_driver's probe is called with the virtbus_device
+as a parameter, it can do a container_of on the virtbus_device to get
+to the struct foo_type foo that it cares about.
+
+Virtbus drivers
+~~~~~~~~~~~~~~~
+Virtbus drivers register with the virtual bus to be matched with virtbus
+devices. They expect to be registered with a probe and remove callback,
+and also support shutdown, suspend, and resume callbacks. They otherwise
+follow the standard driver behavior of having discovery and enumeration
+handled in the bus infrastructure.
+
+Virtbus drivers register themselves with the API entry point virtbus_drv_reg
+and unregister with virtbus_drv_unreg.
+
+Device Enumeration
+~~~~~~~~~~~~~~~~~~
+Enumeration is handled automatically by the bus infrastructure via the
+ida_simple methods.
+
+Device naming and driver binding
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The virtbus_device.dev.name is the canonical name for the device. It is
+built from two other parts:
+
+ - virtbus_device.name (also used for matching).
+ - virtbus_device.id (generated automatically from ida_simple calls)
+
+This allows for multiple virtbus_devices with the same name, which will all
+be matched to the same virtbus_driver. Driver binding is performed by the
+driver core, invoking driver probe() after finding a match between device and driver.
+
+Virtual Bus API entry points
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I was under impression that usage of IDA interface is discouraged in favor
of direct calls to XArray.

IDA is OK, idr should be xarray

What? That's not the job of a virtual bus, a virtual bus is there to
put devices on it and hook them up to drivers.
What do you mean by "two separate kernel objects"? What are the objects
here?

That's just how the driver model works, I'm not quite sure what you are
trying to say here. What is this section for?

I don't understand this documentation at all. Can't you put what you
need in the code itself and have it be auto-generated? This is really
vague stuff that I can't find useful. And if I don't understand it,
well... :)

Why kerneldoc for static functions?
This naming scheme is great to have documented somewhere, why am I just
finding it here? See, your .rst file was useless :(
Make the documentation be generated from this .c file please.

Wait, why would a driver not have an id table? You are matching two

How can we not have a probe? Test for that at registration.

Ugh, you just lost the reference count logic for your call to
device_initialize() above, right? Or did you document the heck out of
this saying that if you call virtbus_dev_register, you MUST call
put_device() to properly clean things up.
Nope, you did not :(

Odd test, what is it supposed to do? If you use kunit, does that make
it easier to test things out?

Please use static inlines for things like this, it makes the type
system clearer

I generally try to discourage the pattern where the device_initialize
is inside a function called register.
The kref inside the struct device should be the only kref for this
memory, and the kref system should be setup close to allocating the
memory. Any non-trivial user tends to require access to the kref
before calling register (which should be done last)

Should this be a cyclic allocation?

This is also stuff that can be useful to do early as the driver can
then use functions like dev_warn/etc

Is something wrong with my search? I couldn't find a user for this?
If the virtbus framework wants to provide a release function then it
should also provide the alloc and require that the virtbus_device be
at offset 0 in the caller's struct so that the above kfree can work.
(ie like netdev does with the whole priv thing)
I have no idea what the virtbus_object is supposed to be doing here.

id is always positive, should be unsigned

The RDMA block does not have its own PCI function, instead it must utilize
the ice driver to gain access to the PCI device. Create a virtual bus
for the RDMA driver to bind to the device data. The device data contains
all of the relevant information that the IRDMA peer will need to access
this PF's IIDC API callbacks.
Note the header file iidc.h is located under include/linux/net/intel

You have a lot of different things all mushed together into one patch,
so much so that this is pretty much impossible for me to review. How
did you all handle it?
Can't this be broken up into smaller, logical, changes that make it
obvious that what you are doing here is correct and makes sense? As it
is, my few comments below show total confusion on my part...
I can think of a few ways that this can be handled better, but as you
know the code best, I'm sure you can come up with a better way.

I had to stare at this multiple times to make sure this really is
correct. Shouldn't the devm api handle this for you?

The virtual device is embedded in another structure that is embedded
inside another one which is next to another object in the same
structure? Am I reading this right?
Who controls the lifetime rules here? virtbus _should_ but it seems
really really complex here and I can't figure it out.
Why so complex?

Shouldn't virtbus_dev_register() print the error message as to what went
wrong? Callers should not be responsible for that.

get_/put_ functions usually grab a reference count. You didn't do that
here :(

Wait the memory for the virtual devices is allocated using
devm_kcalloc()? Is that true? And then that memory is handled by the
reference count logic of the child objects in that structure? That
feels really wrong...
Or am I just still confused about the whole object hierarchy here?

Isn't the joy of using devm* functions such that you never have to free
the memory on your own? Why are you doing that here?
totally lost,

Mustafa Ismail, Jeff Kirsher
From: Shiraz Saleem <shiraz.saleem@intel.com>
Register client virtbus device on the virtbus for the RDMA
virtbus driver (irdma) to bind to. It allows to realize a
single RDMA driver capable of working with multiple netdev
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 virtbus 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.

Isn't dropping this cflags good for a nice simple separate patch to keep
the #include mess from cluttering up a patch that is trying to add
new functionality?

What a total and complete mess of a tangled web you just wove here.
Ok, so you pass in a single pointer, that then dereferences 3 pointers
deep to find the pointer to the virtbus_device structure, but then you
point the parent of that device, back at the original structure's
sub-pointer's device itself.
WTF?
And who owns the memory of this thing that is supposed to be
dynamically controlled by something OUTSIDE of this driver? Who created
that thing 3 pointers deep? What happens when you leak the memory below
(hint, you did), and who is supposed to clean it up if you need to
properly clean it up if something bad happens?

Did you just leak memory?
Yup, you did, you never actually checked the return value of this
function :(
Ugh.
I feel like the virtual bus code is getting better, but this use of the
code, um, no, not ok.
Either way, this series is NOT ready to be merged anywhere, please do
not try to rush things.
Also, what ever happened to my "YOU ALL MUST AGREE TO WORK TOGETHER"
requirement between this group, and the other group trying to do the
same thing? I want to see signed-off-by from EVERYONE involved before
we are going to consider this thing.

OK. This is convoluted. Passing a pointer to the i40e_info object should suffice. So something like,
+static int i40e_init_client_virtdev(struct i40e_info *ldev) {
+ struct pci_dev *pdev = ldev->pcidev;
+ struct virtbus_device *vdev = &ldev->vdev;
+ int ret;
+
+ vdev->name = I40E_PEER_RDMA_NAME;
+ vdev->dev.parent = &pdev->dev;
+ ret = virtbus_dev_register(vdev);
+ if (ret)
+ return ret;
+
+ return 0;
+}

The i40e_info object memory is tied to the PF driver.
The object hierarchy is,
i40e_pf: pointer to i40e_client_instance
----- i40e_client_instance: i40e_info
----- i40e_info: virtbus_device
For each PF, there is a client_instance object allocated.
The i40e_info object is populated and the virtbus_device hanging off this object is registered.
In irdma probe(), we use the container_of macro to get to this i40e_info object from the
virtbus_device. It contains all the ops/info which RDMA driver needs from the PCI function driver.
The lifetime of the i40e_info object (and the virtbus device) is tied to the PF.
When PF goes away, virtbus_device is unregistered and the client_instance object memory
is freed.

We will have all parties cc'ed in the next submission. Would encourage folks to review
and hopefully we can get some consensus.

What is a "PF"?

So you are 3 pointers deep to get a structure that is dynamically
controlled? Why are those "3 pointers" not also represented in sysfs?
You have a heiarchy within the kernel that is not being represented that
way to userspace, why?
Hint, I think this is totally wrong, you need to rework this to be sane.
> For each PF, there is a client_instance object allocated.
Great, make it dynamic and in the device tree.

Great, make that dynamic and inthe device tree.
If you think this is too much, then your whole mess here is too much and
needs to be made a lot simpler.

Ok, that's what you are supposed to do, but why walk back 3 levels?

Careful, these are dynamic structures, you don't get to fully "tie"
anything here.

Hopefully, if no one else has a reference (hint, you never know this.)
If you are relying on this, then you are not using the driver model
correctly.

Then when you post your patches, do so to be obvious that is what you
are asking for, don't try to do a "here's a pull request to take!" type
request like you did here, that's not nice.

I think we can decouple the virtbus_device object from i40e_info object.
Instead allocate a i40e_virtbus_device object which contains
the virtbus_device and a pointer to i40e_info object for the
RDMA driver to consume on probe(). Register it the virtbus, and provide
a release callback to free up its memory.
Sending a patch snippet to hopefully make it clearer.

If there is only one of these per virtbus_device then why do we need

Is the lifetime actually any better? Will ldev be freed and left
danling before virtbus_device is released?

This is not used in irdma for checking any versioning.
This and the version in struct i40e_client are not cleaned up because they are used
between i40e <--> i40iw. And the thought was once i40iw is removed, we can send
a follow on patch to remove this versioning + the global
exported functions i40e_register_client() and i40e_unregister_client() used by i40iw.
For the ice driver, we have already removed all versioning.

Hmmm... I think not. This should be possible to get from netdev. We can send a cleanup follow on patch.

The consumer of the ldev (i.e the rdma driver) will have a
valid ldev when drv->remove() is called as part of the virtbus
device unregister.
It is probably good to set this ldev pointer inside the i40e_virtbus_device
object to NULL in the netdev driver soon after virtbus device unregister.

Yes, this looks a little bit more sane.

I am working on RFC where PCI device is sliced to create sub-functions.
Each sub-function/slice is created dynamically by the user.
User gives sf-number at creation time which will be used for plumbing by
systemd/udev, devlink ports.
This sub-function will have sysfs attributes = sfnumber, irq vectors,
PCI BAR resource files.
sfnumber as sysfs file will be used by systemd/udev to have
deterministic names of netdev and rdma device created on top of
sub-function's 'struct device'.
As opposed to that, matching service devices won't have such attributes.
We stayed away from using mdev bus for such dual purpose in past.
Should we have virtbus that holds 'struct device' created for different
purpose and have different sysfs attributes? Is it ok?
Your opinion will help us do it correctly.

That's fine to do, I was expecting that to happen.

Not exactly.
Here, in i40 use case - there is a PCI function.
This PCI function is used by two drivers:
(1) vendor_foo_netdev.ko creating Netdevice (class net)
(2) vendor_foo_rdma.ko creating RDMA device (class infiniband)
And both drivers are notified using matching service virtbus, which
attempts to create to two virtbus_devices with different driver-id, one
for each class of device.
However, devices of both class (net, infiniband) will have parent device
as PCI device.
In case of sub-functions, created rdma and netdevice will have parent as
the sub-function 'struct device'. This way those SFs gets their
systemd/udev plumbing done rightly.

ok. Thanks a lot.
Lets understand above additional (non sysfs) difference as well on how
virtbus device is getting used differently between sub-functions and
matching service purposes.

That is fine.

huh? The rdma and netdevice will have as their parent device the
virtdevice that is on the virtbus. Not the PCI device's 'struct
device'.

Yes. I meant same when I said "sub-function 'struct device'", which is
nothing bug a virtdevice.
ok. Great. We are on same page now.
As we discussed, if sub-functions uses the bus, it will use the virtbus
and virtdevice device with above discussed differences.
Once I finish internal RFC review for sub-functions, will post it on the
list.
I do not expect RFC to finish before Christmas holidays.

Register irdma as a virtbus driver binding to
'i40e' and 'ice' virtbus devices added from their
respective netdev drivers for each PF. During
irdma probe(), the gen-specific netdev peer device
is obtained from virtbus device to establish an
interface and initialize the HW.

Leon usually asks why another work queue at this point, at least have

Wasn't the whole point of virtual bus to avoid stuff like this? Why
isn't a client the virtual bus object and this information extended
into the driver ops?

How can this happen too? If it doesn't support register then don't
create a virtual device, surely?
I've really developed a strong distate to these random non-functional
'ifs' that seem to get into things.
If it is functional then fine, but if it is an assertion write it as
if (WARN_ON()) to make it clear to readers it can't happen by design

Quite an abnormal coding style to put the entire function under an if,

Don't use pr_* stuff in drivers that have a struct device.

Mixing put and kfree? So confusing. Why are there so many structs and
so much indirection? Very hard to understand if this is right or not.

Again, are these atomics? Looks like no, why test_bit?

Yeah, combination of WQ_MEM_RECLAIM flag and "params" in the name raises
eyebrows immediately.

These are the private interface calls between lan and rdma.
These ops are implemented by RDMA driver but invoked by
netdev driver.

There is some dev_info which should be cleaned up to dev_dbg.
But logging this info is useful to know that this functions VSI (and associated ibdev)
is up and reading for RDMA traffic.
Is info logging to be avoided altogether?

This does look weird. I think the irdma_get_device() was here
just to get to iwdev. And put_device is releasing the refcnt immediately.
Since we are in a VSI close(), we should not need to take refcnt on ibdev
and just deregister it. Will fix this.

Agree. But these are module params that existed in i40iw.
And irdma replaces i40iw and has a module alias
for it.

This wq is used for deferred handling of irdma service tasks.
Such as rebuild/recovery after reset.

This helper is not used and to be removed.
But, yes integrity needs to be assured while read/modify rsrc_array.
irdma_alloc_rsrc() and irdma_free_rsrc() probably warrant
using the non-atomic ver. of set/clear bit since its inside
a lock.
Thanks for the feedback!

Will function tracer (ftrace) output be sufficient here?

Maybe use this opportunity and ditch "deprecated" module parameters?

AFAIK you are supposed to provide things like this as part of your
device driver ops, ie open is probe, close is unbind, etc.

Just test the bit?
if (event->type & BIT(IIDC_EVENT_LINK_CHANGE)) ?
test_bit is the atomic version of those that matches atomic
set_bit/clear_bit

Certainly not at display-by-default level. If every driver printed
when it binds we'd have a mess.

Provide non-module parameter alternatives for all of these, and it can
be OK only because of the module alias, and only if Doug lets you
remove i40iw.

We have system global wqs. Why are they not OK?

Instead of adding a driver specific "roce_enable", use the generic parameter "enable_roce".

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: 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 looked through this for a litle while, it is very very big. I'd like
some of the other people who have sent drivers lately to give it a go
over as well..
A few broad comments
- Do not use the 'err1', 'err2', etc labels for goto unwind
- Please check all uses of rcu, I could not see why some existed
- Use the new rdma mmap api. The whole mmap flow looked wonky to me
- Check explicit casts, I saw alot that where questionable
- Make sure rdma-core still builds after all the kernel uapi header
changes - looks to me like it breaks the build
- Check that atomics should not actually be a refcount_t
- New drivers should use the ops->driver_unregister flow
- devlink in the rdma driver seems very strange, I thought this
should be in the PCI function driver?
- The whole cqp_compl_thread thing looks really weird

Presume your referring to this series?
https://github.com/jgunthorpe/linux/commits/rdma_mmap
At the time it was published, I didn't think it applied to irdma, but rather
benefit those drivers that keyed off an mmap database in their mmap function.
In irdma, there is a doorbell and a push page that are mapped. And the offset
passed in is used to distinguish the 2 (0-for doorbell) and determine the address
to map. Also, in the db scheme, I think there is presumption the mmap comes
down with the key passed back in kernel response struct. For the doorbell page
at least, the mmap in library provider just uses 0.
[....]
> - New drivers should use the ops->driver_unregister flow
https://www.spinics.net/lists/linux-rdma/msg75466.html
"These APIs are intended to support drivers that exist outside the usual
driver core probe()/remove() callbacks. Normally the driver core will
prevent remove() from running concurrently with probe(), once this safety
is lost drivers need more support to get the locking and lifetimes right."
As per this description, it seems ib_unregister_driver() would be
redundant for irdma to use in module exit? virtbus_driver_unregister
should guarantee the remove() callbacks and ib device unregistration.
Or did you mean just instrument ops->dealloc_driver?
Surely I am missing something.

> - The whole cqp_compl_thread thing looks really weird
What is the concern?
Thanks for the feedback. Will work on it.

Yes, it is merged now

All drivers using mmap should be using it.
New drivers should not be using mmap via hard coded keys. The offset
to pass to mmap should always be returned from a system call.
For compatibility insert the hard coded key with the mmap stuff and
use the APIs for lifetime management.
> In irdma, there is a doorbell and a push page that are mapped.
Pretty much all hardware requires these to be per-security domain, so
you have a lifecycle model that matches what the mmap API is now
providing.

It looks like an open coded work queue

The cqp_compl_thread is not a work queue in the sense
that no work is queued to it. It is a thread that is signaled to
check for and handle CQP completion events if present.

How is that not a work queue? The work is the signal to handle CQP
completion events.

Yes we could use the work as a signal. But this would mean,
we allocate a work item, initialize it to an 'identical' value,
queue it up and then free it.
Why is this better than using a single kthread that just
wake ups to handle the CQP completion?

You don't have to allocate a work item every time.

We'd have endless kthreads if people did this everytime they needed a
bit of async work.

Seems pretty premature to ask for a pull request after I rejected your
first 2 submissions and have not seen a valid implementation yet.
Please give me a few days to review this...

Please don't send new RDMA drivers in pull requests to net. This
driver is completely unreviewed at this point.

This was done because you requested a for a single pull request in an
earlier submission 9 months ago. I am fine with breaking up submission,
even though the RDMA driver would be dependent upon the virtual bus and LAN
driver changes.

If I said that I ment a single pull request *to RDMA* with Dave's acks
on the net side, not a single pull request to net.
Given the growth of the net side changes this may be better to use a
shared branch methodology.

I am open to any suggestions you have on submitting these changes that has
the least amount of thrash for all the maintainers involved.
My concerns for submitting the network driver changes to the RDMA tree is
that it will cause David Miller a headache when taking additional LAN
driver changes that would be affected by the changes that were taken into
the RDMA tree.
We can hash this out later if need be, since it is clear there are changes
needed to the current series.

If you send the PR to rdma then you must refrain from sending changes
to net that would conflict with it.
I also do not want a headache with conflicts to a huge rdma driver in
net, so you cannot send it to -net.
Mellanox uses a shared branch approach now, it is working well but
requires discipline to execute.
You can also send your changes to net, wait a cycle then send the rdma
changes. IIRC one of the other drivers is working this way.

Yeah, that will be tough, since we will have *literally* hundreds of
patches for the ice driver for the 5.6 kernel.

Agreed, I do not want to cause you or David Miller any headaches. It was
not clear on what additional changes the RDMA team would have once their
driver got upstream.

Wouldn't a shared branch cause issues for either you or David Miller to
pull from, since it has changes from the RDMA and net-next tree's?

This sounds like the best option currently, since there is still a lot of
work being done in the ice driver. Since Greg wanted to see driver
examples, using the virtual bus, I can send the RDMA driver patches as RFC
in future submissions. This way, we can make sure the implementation is
acceptable and will be ready for submission, once the virtual bus and LAN
driver changes are accepted.

It isn't about your changes. We often do tree-wide change the RDMA
APIs toward the driver. For instance Leon's work to add restracks and
to move allocations out of drivers. If any driver is out of the
rdma.git tree then this is all broken for us.

The shared tree approach requires discipline and bunch of special
considerations go into constructing it and organizing patches to make
it work. When done properly there are no issues.
