HV VHCA is a layer which provides PF to VF communication channel based on
HyperV PCI config channel. It implements Mellanox's Inter VHCA control
communication protocol. The protocol contains control block in order to
pass messages between the PF and VF drivers, and data blocks in order to
pass actual data.
The infrastructure is agent based. Each agent will be responsible of
contiguous buffer blocks in the VHCA config space. This infrastructure will
bind agents to their blocks, and those agents can only access read/write
the buffer blocks assigned to them. Each agent will provide three
callbacks (control, invalidate, cleanup). Control will be invoked when
block-0 is invalidated with a command that concerns this agent. Invalidate
callback will be invoked if one of the blocks assigned to this agent was
invalidated. Cleanup will be invoked before the agent is being freed in
order to clean all of its open resources or deferred works.
Block-0 serves as the control block. All execution commands from the PF
will be written by the PF over this block. VF will ack on those by
writing on block-0 as well. Its format is described by struct
mlx5_hv_vhca_control_block layout.

When calling debugfs functions, there is no need to ever check the

never do something different based on this.
This cleans up a lot of unneeded code and logic around the debugfs

don't need to keep the dentries saved anymore.

List of flows attached to mod header entry is used as implicit reference
counter (mod header entry is deallocated when list becomes free) and as a
mechanism to obtain mod header entry that flow is attached to (through list
head). This is not safe when concurrent modification of list of flows
attached to mod header entry is possible. Proper atomic reference counter
is required to support concurrent access.
As a preparation for extending mod header with reference counting, extract
code that lookups and deletes mod header entry into standalone put/get
helpers. In order to remove this dependency on external locking, extend mod
header entry with reference counter to manage its lifetime and extend flow
structure with direct pointer to mod header entry that flow is attached to.
To remove code duplication between legacy and switchdev mode
implementations that both support mod_hdr functionality, store mod_hdr
table in dedicated structure used by both fdb and kernel namespaces. New
table structure is extended with table lock by one of the following patches
in this series. Implement helper function to get correct mod_hdr table
depending on flow namespace.

Add a pool of flow counters, based on flow counter bulks, removing the
need to allocate a new counter via a costly FW command during the flow
creation process. The time it takes to acquire/release a flow counter
is cut from ~50 [us] to ~50 [ns].
The pool is part of the mlx5 driver instance, and provides flow
counters for aging flows. mlx5_fc_create() was modified to provide
counters for aging flows from the pool by default, and
mlx5_destroy_fc() was modified to release counters back to the pool
for later reuse. If bulk allocation is not supported or fails, and for
non-aging flows, the fallback behavior is to allocate and free
individual counters.
The pool is comprised of three lists of flow counter bulks, one of
fully used bulks, one of partially used bulks, and one of unused
bulks. Counters are provided from the partially used bulks first, to
help limit bulk fragmentation.
The pool maintains a threshold, and strives to maintain the amount of
available counters below it. The pool is increased in size when a
counter acquisition request is made and there are no available
counters, and it is decreased in size when the last counter in a bulk
is released and there are more available counters than the threshold.
All pool size changes are done in the context of the
acquiring/releasing process.
The value of the threshold is directly correlated to the amount of
used counters the pool is providing, while constrained by a hard
maximum, and is recalculated every time a bulk is allocated/freed.
This ensures that the pool only consumes large amounts of memory for
available counters if the pool is being used heavily. When fully
populated and at the hard maximum, the buffer of available counters
consumes ~40 [MB].

Towards introducing the ability to allocate bulks of flow counters,
refactor the flow counter bulk query process, removing functions and
structs whose names indicated being used for flow counter bulk
allocation FW commands, despite them actually only being used to
support bulk querying, and migrate their functionality to correctly
named functions in their natural location, fs_counters.c.
Additionally, optimize the bulk query process by:
* Extracting the memory used for the query to mlx5_fc_stats so
that it is only allocated once, and not for each bulk query.
* Querying all the counters in one function call.

This patch prevents a race between user invoked cached counters
query and a neighbor last usage updater.
The cached flow counter stats can be queried by calling
"mlx5_fc_query_cached" which provides the number of bytes and
packets that passed via this flow since the last time this counter
was queried.
It does so by reducting the last saved stats from the current, cached
stats and then updating the last saved stats with the cached stats.
It also provide the lastuse value for that flow.
Since "mlx5e_tc_update_neigh_used_value" needs to retrieve the
last usage time of encapsulation flows, it calls the flow counter
query method periodically and async to user queries of the flow counter
using cls_flower.
This call is causing the driver to update the last reported bytes and
packets from the cache and therefore, future user queries of the flow
stats will return lower than expected number for bytes and packets
since the last saved stats in the driver was updated async to the last
saved stats in cls_flower.
This causes wrong stats presentation of encapsulation flows to user.
Since the neighbor usage updater only needs the lastuse stats from the
cached counter, the fix is to use a dedicated lastuse query call that
returns the lastuse value without synching between the cached stats and
the last saved stats.

CQE checksum full mode in new HW, provides a full checksum of rx frame.
Covering bytes starting from eth protocol up to last byte in the received
frame (frame_size - ETH_HLEN), as expected by the stack.
Fixing up skb->csum by the driver is not required in such case. This fix
is to avoid wrong checksum calculation in drivers which already support
the new hardware with the new checksum mode.

Max Gurtovoy says:
====================
Those two patches introduce VHCA tunnel mechanism to DEVX interface
needed for Bluefield SOC. See extensive commit messages for more
information.
====================
Based on the mlx5-next branch from
git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux for
dependencies
* branch 'vcha-tunnel':
IB/mlx5: Implement VHCA tunnel mechanism in DEVX
net/mlx5: Introduce VHCA tunnel device capability
|
|
When using the device emulation feature (introduced in Bluefield-1 SOC),
a privileged function (the device emulation manager) will be able to
create a channel to execute commands on behalf of the emulated function.
This channel will be a general object of type VHCA_TUNNEL that will have
a unique ID for each emulated function. This ID will be passed in each
cmd that will be issued by the emulation SW in a well known offset in
the command header.
This channel is needed since the emulated function doesn't have a normal
command interface to the HCA HW, but some basic configuration for that
function is needed (e.g. initialize and enable the HCA). For that matter,
a specific command-set was defined and only those commands will be issued
by the HCA.

Always contain all acceleration functions declarations in
'accel' files, independent to the flags setting.
For this, introduce new flags CONFIG_FPGA_{IPSEC/TLS} and use stubs
where needed.
This obsoletes the need for stubs in 'fpga' files. Remove them.
Also use the new flags in Makefile, to decide whether to compile
TLS-specific or IPSEC-specific objects, or not.

Support bind a qp with counter. If counter is null then bind the qp to the
default counter. Different QP state has different operation:
- RESET: Set the counter field so that it will take effective during
RST2INIT change;
- RTS: Issue an RTS2RTS change to update the QP counter;
- Other: Set the counter field and mark the counter_pending flag, when QP
is moved to RTS state and this flag is set, then issue an RTS2RTS
modification to update the counter.

From git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux
Required for dependencies in the next patches.
* mlx5-next:
net/mlx5: Add rts2rts_qp_counters_set_id field in hca cap
net/mlx5: Properly name the generic WQE control field
net/mlx5: Introduce TLS TX offload hardware bits and structures
net/mlx5: Refactor mlx5_esw_query_functions for modularity
net/mlx5: E-Switch prepare functions change handler to be modular
net/mlx5: Introduce and use mlx5_eswitch_get_total_vports()
|
|
Misc updates from mlx5-next branch:
1) Add the required HW definitions and structures for upcoming TLS
support.
2) Add support for MCQI and MCQS hardware registers for fw version query.
3) Added hardware bits and structures definitions for sub-functions
4) Small code cleanup and improvement for PF pci driver.
5) Bluefield (ECPF) updates and refactoring for better E-Switch
management on ECPF embedded CPU NIC:
5.1) Consolidate querying eswitch number of VFs
5.2) Register event handler at the correct E-Switch init stage
5.3) Setup PF's inline mode and vlan pop when the ECPF is the
E-Swtich manager ( the host PF is basically a VF ).
5.4) Handle Vport UC address changes in switchdev mode.
6) Cleanup the rep and netdev reference when unloading IB rep.

A generic WQE control field is used for different purposes
in different cases.
Use union to allow using the proper name in each case.
