Vlad Buslov 73c718fbb3 net/mlx5e: Remove wrong and superfluous tc pedit header type check
With recent introduction of flow_rule infrastructure drivers no longer
directly include action headers, so it is no longer possible to use
constants defined in them. Instead, one of flow_rule patches substituted
pedit action header constant with hardcoded value '2' in mlx5
set_pedit_val() function conditional which verifies that header type is in
range of values allowed by pedit action. That conditional is now both
wrong (hardcoded value is '2' but __PEDIT_HDR_TYPE_MAX is 6 in current
version) and superfluous (pedit action already verifies that header type is
in allowed range during init). Remove the described check from mlx5 code.

As it is, doing something like

  # iw phy phy0 interface add foobar type ibss

on a firmware that doesn't have ad-hoc support just yields failures of
HostCmd_CMD_SET_BSS_MODE, which happened to return a '-1' error code
(-EPERM? not really right...) and sometimes may even crash the firmware
along the way.

Let's parse the firmware capability flag while registering the wiphy, so
we don't allow attempting IBSS at all, and we get a proper -EOPNOTSUPP
from nl80211 instead.

This macro will be used in more places not just the cfg80211.c. It makes
sense to pass some common struct to it as "struct wiphy" is mostly
referenced in cfg80211 code only.

A very common one (used above the bus abstraction layer) is struct
brcmf_pub. Many functions already keep reference to it which will make
using bphy_err() simpler. It should also allow extending that macro's
logic if it's ever needed.

Heiner Kallweit eb160971af r8169: remove unneeded mmiowb barriers
writex() has implicit barriers, that's what makes it different from
writex_relaxed(). Therefore these calls to mmiowb() can be removed.

This patch was recently reverted due to a dependency with another
problematic patch. But because it didn't contribute to the problem
it was rebased and can be resubmitted.

Add a dedicated thermal zone for each QSFP/SFP module. The current
temperature is obtained from the module's temperature sensor and the
trip points are set based on the warning and critical thresholds
read from the module.

A cooling device (fan) is bound to all the thermal zones. The
thermal zone governor is set to user space in order to avoid
collisions between thermal zones.
For example, one thermal zone might want to increase the speed of
the fan, whereas another one would like to decrease it.

Deferring this decision to user space allows the user to the take
the most suitable decision.

mlxsw_sp_pg_buf_delay_get(), and thus leaves the loop as quantity in

given priority is configured with a wrong size.

Fix by introducing a loop-local variable, delay_cells. Rename thres to

Bodong Wang says,
 
 BlueField device is a multi-core ARM processor in a highly integrated
 system on chip coupled with the ConnectX interconnect controller.
 BlueField device can be presented in one out of two modes:
 
 - SEPARATED_HOST: ARM processors as a separated and orthogonal host
   like any other external host in the multi-host virtualization model.
 - EMBEDDED_CPU: ARM processors as Embedded CPU (EC) and part of the
   external hosts virtualization model.
 
 While existing driver already supports the device on separated_host
 mode, this patch series focus on the functionalities of embedded_cpu
 mode.
 
 On embedded_cpu mode, BlueField device exposes regular network
 controller PCI function in the BlueField host(e.g, x86). However, a
 separate PCI function called Embedded CPU Physical Function(ECPF) is
 also added to the ARM host side, where standard Linux distributions is
 able to run on the ARM cores. Depends on the NV configuration from
 firmware, ECPF can be the e-switch manager and firmware pages supplier.
 If ECPF is configured as e-switch manager and page supplier, it will
 take over the responsibilities from the PF on BlueField host includes:
 - Owns, controls and manages all e-switch parts, and takes e-switch
   traffic by default. It also should perform ENABLE_HCA for the host
   PF just like a PF does for its VFs.
 - Provides and manages the ICM host memory required for the HCA to
   store various contexts for itself, the PF and VFs belong the
   e-switch it manages.
 
 The PF on BlueField host side is still responsible for:
 - Control its own permanent MAC.
 - PCI and SRIOV configurations and perform ENABLE_HCA for its VFs.
 
 The ECPF can also retrieve information about the external host it
 controls, like host identifier, PCI BDF and number of virtual functions.
 As these parameters may be changed dynamically, an event will be triggered
 to the driver on ECPF side.

Bodong Wang c96692fb8f net/mlx5: E-Switch, Allow transition to offloads mode for ECPF
Currently, the e-switch driver requires going to legacy mode before
changing to the offloads mode. This makes sense for regular case as
the legacy mode is done by creating VFs.

However, it's problematic when ECPF is the eswitch manager. In such
case, ECPF will control the vports on peer host including the peer
PF and VFs. But ECPF doesn't need and shall not create VFs as the
VFs are created in the peer PF host.

Grant ECPF the ability to change from none to the offloads mode. Note
that currently the only way to go back to none mode is by unloading
the ECPF driver.

Bodong Wang a3888f33db net/mlx5: E-Switch, Load/unload VF reps according to event from host PF
When host PF changes the number of VFs, the ECPF esw driver will get
a FW event. It should query the number of VFs enabled by host PF and
update the VF reps accordingly. Note that host PF can't change the
number of VFs dynamically, it has to reset the number of VFs to 0
before changing to a new positive number.

The host event is registered when driver is moving to switchdev mode,
and it's the last step to do in esw_offloads_init. It's unregistered
and the work queue is flushed when driver quits from switchdev mode.
In this way, the host event and devlink command are serialized.

When driver is enabling switchdev mode, pay attention to the following
two facts:
1. Host PF must not have VF initialized as the flow table in ECPF has
   ENCAP enabled as default. Such flow table can't be created with
   existing initialized VFs.
2. ECPF doesn't know how many VFs the host PF will enable, ECPF
   offloads flow steering shall create the flow table/groups based on
   the max number of VFs possibly supported by host PF.

In offloads mode, the current implementation puts the uplink
representor at index zero of the vport reps array. It is not "natural"
to place it at index 0 since we want to put the representor for vport

So, we want to have a different placeholder for uplink vport and
representor. It was placed at the end of vport and rep array. Since
vport number can no longer act as an index into the vport or
representors arrays, use functions to map vport numbers to indices
when accessing the vports or representors arrays, and vice versa.

Bodong Wang f8e8fa0262 net/mlx5: E-Switch, Centralize repersentor reg/unreg to eswitch driver
Eswitch has two users: IB and ETH. They both register repersentors
when mlx5 interface is added, and unregister the repersentors when
mlx5 interface is removed. Ideally, each driver should only deal with
the entities which are unique to itself. However, current IB and ETH
drivers have to perform the following eswitch operations:

1. When registering, specify how many vports to register. This number
   is the same for both drivers which is the total available vport
   numbers.
2. When unregistering, specify the number of registered vports to do
   unregister. Also, unload the repersentors which are already loaded.

It's unnecessary for eswitch driver to hands out the control of above
operations to individual driver users, as they're not unique to each
driver. Instead, such operations should be centralized to eswitch
driver. This consolidates eswitch control flow, and simplified IB and
ETH driver.

Bodong Wang c9b99abcf2 net/mlx5: E-Switch, Split VF and special vports for offloads mode
When driver is entering offloads mode, there are two major tasks to
do: initialize flow steering and create representors. Flow steering
should make sure enough flow table/group spaces are reserved for all
reps. Representors will be created in a group, all or none.

With the introduction of ECPF, flow steering should still reserve the
same spaces. But, the representors are not always loaded/unloaded in a
single piece. Once ECPF is in offloads mode, it will get the number
of VF changing event from host PF. In such scenario, only the VF reps
should be loaded/unloaded, not the reps for special vports (such as
the uplink vport).

Thus, when entering offloads mode, driver should specify the total
number of reps, and the number of VF reps separately. When leaving
offloads mode, the cleanup should use the information self-contained
in eswitch such as number of VFs.

Bodong Wang 591905ba96 net/mlx5: Introduce Mellanox SmartNIC and modify page management logic
Mellanox's SmartNIC combines embedded CPU(e.g, ARM) processing power
with advanced network offloads to accelerate a multitude of security,
networking and storage applications.

With the introduction of the SmartNIC, there is a new PCI function
called Embedded CPU Physical Function(ECPF). And it's possible for a
PF to get its ICM pages from the ECPF PCI function. Driver shall
identify if it is running on such a function by reading a bit in
the initialization segment.

When firmware asks for pages, it would issue a page request event
specifying how many pages it requests and for which function. That
driver responds with a manage_pages command providing the requested
pages along with an indication for which function it is providing these
pages.

The encoding before this patch was as follows:
    function_id == 0: pages are requested for the function receiving
                      the EQE.
    function_id != 0: pages are requested for VF identified by the
                      function_id value

A new one bit field in the EQE identifies that pages are requested for
the ECPF.

The notion of page_supplier can be introduced here and to support that,
manage pages and query pages were modified so firmware can distinguish
the following cases:

1. Function provides pages for itself
2. PF provides pages for its VF
3. ECPF provides pages to itself
4. ECPF provides pages for another function

This distinction is possible through the introduction of the bit
"embedded_cpu_function" in query_pages, manage_pages and page request
EQE.

Robert Stonehouse 50f444aa50 sfc: ensure recovery after allocation failures
After failing to allocate a receive buffer the driver may fail to ever
request additional allocations. EF10 NICs require new receive buffers to
be pushed in batches of eight or more. The test for whether a slow fill

downside to *always* requesting a slow fill if we failed to allocate a

Currently the ethtool_regs version is set to 0 for FEC devices.

Use this field to store the register dump version exposed by the
kernel. The choosen version 2 corresponds to the kernel compile test:

        #if defined(CONFIG_M523x) || defined(CONFIG_M527x)
        || defined(CONFIG_M528x) || defined(CONFIG_M520x)
        || defined(CONFIG_M532x) || defined(CONFIG_ARM)
        || defined(CONFIG_ARM64) || defined(CONFIG_COMPILE_TEST)

and version 1 corresponds to the opposite. Binaries of ethtool unaware
of this version will dump the whole set as usual.

Vishal Kulkarni d429005fdf cxgb4/cxgb4vf: Add support for SGE doorbell queue timer
T6 introduced a Timer Mechanism in SGE called the
SGE Doorbell Queue Timer. With this we can now configure
TX Queues to get CIDX Updates when:

    Time(CIDX == PIDX) >= Timer

Previously we rely on TX Queue Status Page updates by hardware
for DMA completions. This will make Hardware/Firmware actually
deliver the CIDX Updates as Ingress Queue messages with
commensurate Interrupts.

So we now have a new RX Path component for processing CIDX Updates
and reclaiming TX Descriptors faster.

At this point, the phydev->state_queue() has been added back onto the

Avraham Stern 99944b7306 iwlwifi: mvm: stop static queues correctly
AP interfaces still use some static TX queues (for probes,
broadcast and multicast frames). These queues were not stopped
correctly when the transport layer indicated the queue should be
stopped. As a result, when flushing the queues, new frames from
the overflow queue were tx'd, so the queues still had frames after
flushing. This ended up in an assert since trying to remove a station
with non-empty queues.

Fix it by stopping the static queues correctly when required.

Haim Dreyfuss 48e775e66e iwlwifi: mvm: add support for 32kHz external clock indication
In low power modes, the chip clock source for platform integrated
devices is 32kHz. It is generated internally and supplied by a crystal
oscillator. However using a 32kHz sourced from crystal oscillator
has high power penalty.

There is an option to get an external 32kHz clock from the platform. Past
experience shows that the reliability is platform dependent,
i.e. on some platforms it works good and on other it doesn’t.

Working from external clock will save 0.5 mW in sleep state, from overall
1.8mW that we have today, i.e. almost 30%.

Each OEM can enable or disable the use of the external 32kHz clock by
setting a BIOS configuration. In case the OEM configured to use 32kHz
external clock the driver will pass this indication to the FW.

Sara Sharon 2ae48edcf7 iwlwifi: pcie: fix TX while flushing
When flushing TX queues no new TX should go into the system.
However, in the following scenario we get TX:
1. Queues are stopped and there are packets in overflow queue
2. Station is removed and flush begins
3. Flush empties space, and reclaim path TXes SKB from overflow
   queue.

Note that the fact the queues are stopped during the process
doesn't matter - the packet will be TXed since the TX path
doesn't care if TX queues are stopped or not, just if there is
space in the queue, which there is, since we just freed a
packet.

A fix here is rather complicated, since the flow is very racy.

Change code not to warn if we are TXing from overflow TX.
In case there is TX from both overflow TX and TX path we will
miss a warning we optimally had, but we can live with that.

Make sure we don't return before overflow queue is empty, otherwise
we will think queues are empty, but they will be refilled, resulting
with assert.

Avraham Stern cee859fe9a iwlwifi: mvm: Fix possible NULL pointer dereference
iwl_mvm_te_clear_data() is called for cleanup in case sending
the HOT_SPOT_CMD failed. However, in case sending the command
caused a fw error and restart (e.g. if the command is not supported)
then the te_data pointer may no longer be valid, which leads to
a NULL pointer dereference.

Fix it by checking that the te_data pointer is not NULL before
dereferencing it.

Mordechay Goodstein f130bb75d8 iwlwifi: add FW recovery flow
Add new API and TLV for the ability to send commands in the beginning
and end of reset flow.

The full flow of recovery is:

1. While loading FW, get address (from the TLV) of target buffer
   to read in case of reset
2. If an error/assert happens read the address data from step 1.
3. Reset the HW and load the FW.
4. Send the data read in step 2.
5. Add station keys
6. Send notification to FW that reset flow is done.

The main use of the recovery flow is for support in PN/SN recovery
when offloaded

Shahar S Matityahu b61a661092 iwlwifi: dbg_ini: rewrite trigger flow and align to FW API changes
Trigger field ignore_default was changed to override_trig.
The first byte of the field indicates the driver to override existing
configuration or keep the previous one
The second byte of the field indicated the driver to replace the regions
of the previous trigger or to append new regions to it.

Change the way the active triggers are maintained to support trigger
override in different apply points.
Do this by making a trigger that updates at runtime by the
triggers that are being used in the different apply points.

In case of an assert, the driver does not reconfigure the triggers
and uses the old configuration which leads to undefined behavior.
Solve this by clearing the triggers in assert recovery flow.

Allocator swaps the pending requests with 0 when it starts
working. This means that relying on it n RX path to decide if
to move to emergency is not always a good idea, since it may
be zero, but there are still a lot of unallocated RBs in the
system. Change allocator to decrement the pending requests on
real time. It is more expensive since it accesses the atomic
variable more times, but it gives the RX path a better idea
of the system's status.
