mlx5 subfunction support
Parav Pandit Says:
=================
This patchset introduces support for mlx5 subfunction (SF).
A subfunction is a lightweight function that has a parent PCI function on
which it is deployed. mlx5 subfunction has its own function capabilities
and its own resources. This means a subfunction has its own dedicated
queues(txq, rxq, cq, eq). These queues are neither shared nor stolen from
the parent PCI function.
When subfunction is RDMA capable, it has its own QP1, GID table and rdma
resources neither shared nor stolen from the parent PCI function.
A subfunction has dedicated window in PCI BAR space that is not shared
with the other subfunctions or parent PCI function. This ensures that all
class devices of the subfunction accesses only assigned PCI BAR space.
A Subfunction supports eswitch representation through which it supports tc
offloads. User must configure eswitch to send/receive packets from/to
subfunction port.
Subfunctions share PCI level resources such as PCI MSI-X IRQs with
their other subfunctions and/or with its parent PCI function.
Patch summary:
--------------
Patch 1 to 4 prepares devlink
patch 5 to 7 mlx5 adds SF device support
Patch 8 to 11 mlx5 adds SF devlink port support
Patch 12 and 14 adds documentation
Patch-1 prepares code to handle multiple port function attributes
Patch-2 introduces devlink pcisf port flavour similar to pcipf and pcivf
Patch-3 adds port add and delete driver callbacks
Patch-4 adds port function state get and set callbacks
Patch-5 mlx5 vhca event notifier support to distribute subfunction
state change notification
Patch-6 adds SF auxiliary device
Patch-7 adds SF auxiliary driver
Patch-8 prepares eswitch to handler SF vport
Patch-9 adds eswitch helpers to add/remove SF vport
Patch-10 implements devlink port add/del callbacks
Patch-11 implements devlink port function get/set callbacks
Patch-12 to 14 adds documentation
Patch-12 added mlx5 port function documentation
Patch-13 adds subfunction documentation
Patch-14 adds mlx5 subfunction documentation
Subfunction support is discussed in detail in RFC [1] and [2].
RFC [1] and extension [2] describes requirements, design and proposed
plumbing using devlink, auxiliary bus and sysfs for systemd/udev
support. Functionality of this patchset is best explained using real
examples further below.
overview:
--------
A subfunction can be created and deleted by a user using devlink port
add/delete interface.
A subfunction can be configured using devlink port function attribute
before its activated.
When a subfunction is activated, it results in an auxiliary device on
the host PCI device where it is deployed. A driver binds to the
auxiliary device that further creates supported class devices.
example subfunction usage sequence:
-----------------------------------
Change device to switchdev mode:
$ devlink dev eswitch set pci/0000:06:00.0 mode switchdev
Add a devlink port of subfunction flavour:
$ devlink port add pci/0000:06:00.0 flavour pcisf pfnum 0 sfnum 88
Configure mac address of the port function:
$ devlink port function set ens2f0npf0sf88 hw_addr 00:00:00:00:88:88
Now activate the function:
$ devlink port function set ens2f0npf0sf88 state active
Now use the auxiliary device and class devices:
$ devlink dev show
pci/0000:06:00.0
auxiliary/mlx5_core.sf.4
$ ip link show
127: ens2f0np0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000

After use inactivate the function:
$ devlink port function set ens2f0npf0sf88 state inactive
Now delete the subfunction port:
$ devlink port del ens2f0npf0sf88

net/mlx5: SF, Add auxiliary device support
Introduce API to add and delete an auxiliary device for an SF.
Each SF has its own dedicated window in the PCI BAR 2.
SF device is similar to PCI PF and VF that supports multiple class of
devices such as net, rdma and vdpa.
SF device will be added or removed in subsequent patch during SF
devlink port function state change command.
A subfunction device exposes user supplied subfunction number which will
be further used by systemd/udev to have deterministic name for its
netdevice and rdma device.
An mlx5 subfunction auxiliary device example:
$ devlink dev eswitch set pci/0000:06:00.0 mode switchdev
$ devlink port show
pci/0000:06:00.0/65535: type eth netdev ens2f0np0 flavour physical port 0 splittable false
$ devlink port add pci/0000:06:00.0 flavour pcisf pfnum 0 sfnum 88
pci/0000:08:00.0/32768: type eth netdev eth6 flavour pcisf controller 0 pfnum 0 sfnum 88 external false splittable false
function:
hw_addr 00:00:00:00:00:00 state inactive opstate detached
$ devlink port show ens2f0npf0sf88
pci/0000:06:00.0/32768: type eth netdev ens2f0npf0sf88 flavour pcisf controller 0 pfnum 0 sfnum 88 external false splittable false
function:

$ devlink port function set ens2f0npf0sf88 hw_addr 00:00:00:00:88:88 state active
On activation,
$ ls -l /sys/bus/auxiliary/devices/

ARM: SoC drivers for v5.11
There are a couple of subsystems maintained by other people that
merge their drivers through the SoC tree, those changes include:
- The SCMI firmware framework gains support for sensor notifications
and for controlling voltage domains.
- A large update for the Tegra memory controller driver, integrating
it better with the interconnect framework
- The memory controller subsystem gains support for Mediatek MT8192
- The reset controller framework gains support for sharing pulsed
resets
For Soc specific drivers in drivers/soc, the main changes are
- The Allwinner/sunxi MBUS gets a rework for the way it handles
dma_map_ops and offsets between physical and dma address spaces.
- An errata fix plus some cleanups for Freescale Layerscape SoCs
- A cleanup for renesas drivers regarding MMIO accesses.
- New SoC specific drivers for Mediatek MT8192 and MT8183 power domains
- New SoC specific drivers for Aspeed AST2600 LPC bus control
and SoC identification.
- Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660
and SDX55.
- A rework of the TI AM33xx 'genpd' power domain support to use
information from DT instead of platform data
- Support for TI AM64x SoCs
- Allow building some Amlogic drivers as modules instead of built-in
Finally, there are numerous cleanups and smaller bug fixes for
Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
Renesas, and Xilinx SoCs.
There is a trivial conflict in the cedrus driver, with two branches
adding the same CEDRUS_CAPABILITY_H265_DEC flag, and another trivial
remove/remove conflict in linux/dma-mapping.h.

- iwlwifi: support new 6 GHz frequency band
- ath11k: Fast Initial Link Setup (FILS)
- mt7915: dual band concurrent (DBDC) support
- net: ipa: add basic support for IPA v4.5
Refactor:
- a few pieces of in_interrupt() cleanup work from Sebastian Andrzej
Siewior
- phy: add support for shared interrupts; get rid of multiple driver
APIs and have the drivers write a full IRQ handler, slight growth
of driver code should be compensated by the simpler API which also
allows shared IRQs
- add common code for handling netdev per-cpu counters
- move TX packet re-allocation from Ethernet switch tag drivers to a
central place
- improve efficiency and rename nla_strlcpy
- number of W=1 warning cleanups as we now catch those in a patchwork
build bot
Old code removal:
- wan: delete the DLCI / SDLA drivers
- wimax: move to staging
- wifi: remove old WDS wifi bridging support"

docs: make reporting-bugs.rst obsolete
Make various places which point to Documentation/admin-guide/reporting-bugs.rst point to Documentation/admin-guide/reporting-issues.rst instead. That document is brand new and as of now is not completely finished. But even at this stage it's a lot more helpful and accurate than reporting-bugs.rst. Hence also add a note to reporting-bugs.rst, telling people they're better off reading reporting-issues.rst instead. reporting-bugs.rst is scheduled for removal once reporting-issues.rst is considered ready.

net: ena: update ena documentation
The PCI vendor IDs in the documentation inaccurately describe the ENA devices. For example, the 1d0f:ec20 can have LLQ support. The driver loads in LLQ mode by default, and a message is printed to the kernel ring if the mode isn't supported by the device, so the device table isn't needed. Also, LLQ can support various entry sizes, so the documentation is updated to reflect that. Interrupt moderation description is also updated to be more accurate.

net: ena: Change RSS related macros and variables names
The formal name changes to "ENA_ADMIN_RSS_INDIRECTION_TABLE_CONFIG". Indirection is the ability to reference "something" using "something else" instead of the value itself. Indirection table, as the name implies, is the ability to reference CPU/Queue value using hash-to-CPU table instead of CPU/Queue itself. This patch renames the variable keys_num, which describes the number of words in the RSS hash key, to key_parts which makes its purpose clearer in RSS context.

Documentation: intel: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

docs: networking: reorganize driver documentation again
Organize driver documentation by device type. Most documents have fairly verbose yet uninformative names, so let users first select a well defined device type, and then search for a particular driver. While at it rename the section from Vendor drivers to Hardware drivers. This seems more accurate, besides people sometimes refer to out-of-tree drivers as vendor drivers.
