Merge branch 'devlink-mlx5-add-port-function-attributes-for-ipsec'

Saeed Mahameed says:

====================
{devlink,mlx5}: Add port function attributes for ipsec

From Dima:

Introduce hypervisor-level control knobs to set the functionality of PCI
VF devices passed through to guests. The administrator of a hypervisor
host may choose to change the settings of a port function from the
defaults configured by the device firmware.

The software stack has two types of IPsec offload - crypto and packet.
Specifically, the ip xfrm command has sub-commands for "state" and
"policy" that have an "offload" parameter. With ip xfrm state, both
crypto and packet offload types are supported, while ip xfrm policy can
only be offloaded in packet mode.

The series introduces two new boolean attributes of a port function:
ipsec_crypto and ipsec_packet. The goal is to provide a similar level of
granularity for controlling VF IPsec offload capabilities, which would
be aligned with the software model. This will allow users to decide if
they want both types of offload enabled for a VF, just one of them, or
none at all (which is the default).

At a high level, the difference between the two knobs is that with
ipsec_crypto, only XFRM state can be offloaded. Specifically, only the
crypto operation (Encrypt/Decrypt) is offloaded. With ipsec_packet, both
XFRM state and policy can be offloaded. Furthermore, in addition to
crypto operation offload, IPsec encapsulation is also offloaded. For
XFRM state, choosing between crypto and packet offload types is
possible. From the HW perspective, different resources may be required
for each offload type.

Examples of when a user prefers to enable IPsec packet offload for a VF
when using switchdev mode:

$ devlink port show pci/0000:06:00.0/1
pci/0000:06:00.0/1: type eth netdev enp6s0pf0vf0 flavour pcivf pfnum 0 vfnum 0
function:
hw_addr 00:00:00:00:00:00 roce enable migratable disable ipsec_crypto disable ipsec_packet disable

$ devlink port function set pci/0000:06:00.0/1 ipsec_packet enable

$ devlink port show pci/0000:06:00.0/1
pci/0000:06:00.0/1: type eth netdev enp6s0pf0vf0 flavour pcivf pfnum 0 vfnum 0
function:
hw_addr 00:00:00:00:00:00 roce enable migratable disable ipsec_crypto disable ipsec_packet enable

This enables the corresponding IPsec capability of the function before
it's enumerated, so when the driver reads the capability from the device
firmware, it is enabled. The driver is then able to configure
corresponding features and ops of the VF net device to support IPsec
state and policy offloading.

devlink: Expose port function commands to control IPsec packet offloads

Expose port function commands to enable / disable IPsec packet offloads,
this is used to control the port IPsec capabilities.

When IPsec packet is disabled for a function of the port (default),
function cannot offload IPsec packet operations (encapsulation and XFRM
policy offload). When enabled, IPsec packet operations can be offloaded
by the function of the port, which includes crypto operation
(Encrypt/Decrypt), IPsec encapsulation and XFRM state and policy
offload.

Example of a PCI VF port which supports IPsec packet offloads:

$ devlink port show pci/0000:06:00.0/1

Merge branch 'devlink-add-port-function-attribute-to-enable-disable-roce-and-migratable'

Shay Drory says:

====================
devlink: Add port function attribute to enable/disable Roce and migratable

This series is a complete rewrite of the series "devlink: Add port
function attribute to enable/disable roce"
link:
https://lore.kernel.org/netdev/20221102163954.279266-1-danielj@nvidia.com/

Currently mlx5 PCI VF and SF are enabled by default for RoCE
functionality. And mlx5 PCI VF is disable by dafault for migratable
functionality.

Currently a user does not have the ability to disable RoCE for a PCI
VF/SF device before such device is enumerated by the driver.

User is also incapable to do such setting from smartnic scenario for a
VF from the smartnic.

Current 'enable_roce' device knob is limited to do setting only at
driverinit time. By this time device is already created and firmware has
already allocated necessary system memory for supporting RoCE.

Also, Currently a user does not have the ability to enable migratable
for a PCI VF.

The above are a hyper visor level control, to set the functionality of
devices passed through to guests.

This is achieved by extending existing 'port function' object to control
capabilities of a function. This enables users to control capability of
the device before enumeration.

Examples when user prefers to disable RoCE for a VF when using switchdev
mode:

$ devlink port show pci/0000:06:00.0/1
pci/0000:06:00.0/1: type eth netdev pf0vf0 flavour pcivf controller 0
pfnum 0 vfnum 0 external false splittable false
function:
hw_addr 00:00:00:00:00:00 roce enable

$ devlink port function set pci/0000:06:00.0/1 roce disable

$ devlink port show pci/0000:06:00.0/1
pci/0000:06:00.0/1: type eth netdev pf0vf0 flavour pcivf controller 0
pfnum 0 vfnum 0 external false splittable false
function:
hw_addr 00:00:00:00:00:00 roce disable

FAQs:
-----
1. What does roce enable/disable do?
Ans: It disables RoCE capability of the function before its enumerated,
so when driver reads the capability from the device firmware, it is
disabled.
At this point RDMA stack will not be able to create UD, QP1, RC, XRC
type of QPs. When RoCE is disabled, the GID table of all ports of the
device is disabled in the device and software stack.

2. How is the roce 'port function' option different from existing
devlink param?
Ans: RoCE attribute at the port function level disables the RoCE
capability at the specific function level; while enable_roce only does
at the software level.

3. Why is this option for disabling only RoCE and not the whole RDMA
device?
Ans: Because user still wants to use the RDMA device for non RoCE
commands in more memory efficient way.

devlink: Expose port function commands to control migratable

Expose port function commands to enable / disable migratable
capability, this is used to set the port function as migratable.

Live migration is the process of transferring a live virtual machine
from one physical host to another without disrupting its normal
operation.

In order for a VM to be able to perform LM, all the VM components must
be able to perform migration. e.g.: to be migratable.
In order for VF to be migratable, VF must be bound to VFIO driver with
migration support.

When migratable capability is enabled for a function of the port, the
device is making the necessary preparations for the function to be
migratable, which might include disabling features which cannot be
migrated.

Example of LM with migratable function configuration:
Set migratable of the VF's port function.

$ devlink port show pci/0000:06:00.0/2
pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0
vfnum 1
function:
hw_addr 00:00:00:00:00:00 migratable disable

$ devlink port function set pci/0000:06:00.0/2 migratable enable

$ devlink port show pci/0000:06:00.0/2
pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0
vfnum 1
function:
hw_addr 00:00:00:00:00:00 migratable enable

Bind VF to VFIO driver with migration support:
$ echo <pci_id> > /sys/bus/pci/devices/0000:08:00.0/driver/unbind
$ echo mlx5_vfio_pci > /sys/bus/pci/devices/0000:08:00.0/driver_override
$ echo <pci_id> > /sys/bus/pci/devices/0000:08:00.0/driver/bind

Attach VF to the VM.
Start the VM.
Perform LM.

devlink: Expose port function commands to control RoCE

Expose port function commands to enable / disable RoCE, this is used to
control the port RoCE device capabilities.

When RoCE is disabled for a function of the port, function cannot create
any RoCE specific resources (e.g GID table).
It also saves system memory utilization. For example disabling RoCE enable a
VF/SF saves 1 Mbytes of system memory per function.

Example of a PCI VF port which supports function configuration:
Set RoCE of the VF's port function.

This patch series implements devlink-rate for ice driv

Merge branch 'implement-devlink-rate-api-and-extend-it'

Michal Wilczynski says:

====================
Implement devlink-rate API and extend it

This patch series implements devlink-rate for ice driver. Unfortunately
current API isn't flexible enough for our use case, so there is a need to
extend it. Some functions have been introduced to enable the driver to
export current Tx scheduling configuration.

Pasting justification for this series from commit implementing devlink-rate
in ice driver(that is a part of this series):

There is a need to support modification of Tx scheduler tree, in the
ice driver. This will allow user to control Tx settings of each node in
the internal hierarchy of nodes. As a result user will be able to use
Hierarchy QoS implemented entirely in the hardware.

This patch implemenents devlink-rate API. It also exports initial
default hierarchy. It's mostly dictated by the fact that the tree
can't be removed entirely, all we can do is enable the user to modify
it. For example root node shouldn't ever be removed, also nodes that
have children are off-limits.

Example initial tree with 2 VF's:

[root@fedora ~]# devlink port function rate show
pci/0000:4b:00.0/node_27: type node parent node_26
pci/0000:4b:00.0/node_26: type node parent node_0
pci/0000:4b:00.0/node_34: type node parent node_33
pci/0000:4b:00.0/node_33: type node parent node_32

pci/0000:4b:00.0/node_21: type node parent node_20
pci/0000:4b:00.0/node_20: type node parent node_3
pci/0000:4b:00.0/node_14: type node parent node_5
pci/0000:4b:00.0/node_5: type node parent node_3
pci/0000:4b:00.0/node_13: type node parent node_4
pci/0000:4b:00.0/node_12: type node parent node_4
pci/0000:4b:00.0/node_11: type node parent node_4
pci/0000:4b:00.0/node_10: type node parent node_4
pci/0000:4b:00.0/node_9: type node parent node_4
pci/0000:4b:00.0/node_8: type node parent node_4
pci/0000:4b:00.0/node_7: type node parent node_4
pci/0000:4b:00.0/node_6: type node parent node_4
pci/0000:4b:00.0/node_4: type node parent node_3
pci/0000:4b:00.0/node_3: type node parent node_16
pci/0000:4b:00.0/node_16: type node parent node_15
pci/0000:4b:00.0/node_15: type node parent node_0
pci/0000:4b:00.0/node_2: type node parent node_1
pci/0000:4b:00.0/node_1: type node parent node_0
pci/0000:4b:00.0/node_0: type node
pci/0000:4b:00.0/1: type leaf parent node_27
pci/0000:4b:00.0/2: type leaf parent node_27

Let me visualize part of the tree:

+---------+
| node_0 |
+---------+
|
+----v----+
| node_26 |
+----+----+
|
+----v----+
| node_27 |
+----+----+
|
|-----------------|
+----v----+ +----v----+
| VF 1 | | VF 2 |
+----+----+ +----+----+

So at this point there is a couple things that can be done.
For example we could only assign parameters to VF's.

[root@fedora ~]# devlink port function rate set pci/0000:4b:00.0/1 \
tx_max 5Gbps

This would cap the VF 1 BW to 5Gbps.

But let's say you would like to create a completely new branch.
This can be done like this:

[root@fedora ~]# devlink port function rate add \
pci/0000:4b:00.0/node_custom parent node_0
[root@fedora ~]# devlink port function rate add \
pci/0000:4b:00.0/node_custom_1 parent node_custom
[root@fedora ~]# devlink port function rate set \
pci/0000:4b:00.0/1 parent node_custom_1

This creates a completely new branch and reassigns VF 1 to it.

A number of parameters is supported per each node: tx_max, tx_share,
tx_priority and tx_weight.
