Under heavy traffic, the BlueField Gigabit interface can
become unresponsive. This is due to a possible race condition
in the mlxbf_gige_rx_packet function, where the function exits
with producer and consumer indices equal but there are remaining
packet(s) to be processed. In order to prevent this situation,
read receive consumer index *before* the HW replenish so that
the mlxbf_gige_rx_packet function returns an accurate return
value even if a packet is received into just-replenished buffer
prior to exiting this routine. If the just-replenished buffer
is received and occupies the last RX ring entry, the interface
would not recover and instead would encounter RX packet drops
related to internal buffer shortages since the driver RX logic
is not being triggered to drain the RX ring. This patch will
address and prevent this "ring full" condition.

====================
mlx5-updates-2023-12-20
mlx5 Socket direct support and management PF profile.
Tariq Says:
===========
Support Socket-Direct multi-dev netdev
This series adds support for combining multiple devices (PFs) of the
same port under one netdev instance. Passing traffic through different
devices belonging to different NUMA sockets saves cross-numa traffic and
allows apps running on the same netdev from different numas to still
feel a sense of proximity to the device and achieve improved
performance.
We achieve this by grouping PFs together, and creating the netdev only
once all group members are probed. Symmetrically, we destroy the netdev
once any of the PFs is removed.
The channels are distributed between all devices, a proper configuration
would utilize the correct close numa when working on a certain app/cpu.
We pick one device to be a primary (leader), and it fills a special
role. The other devices (secondaries) are disconnected from the network
in the chip level (set to silent mode). All RX/TX traffic is steered
through the primary to/from the secondaries.
Currently, we limit the support to PFs only, and up to two devices
(sockets).
===========
Armen Says:
===========
Management PF support and module integration
This patch rolls out comprehensive support for the Management Physical
Function (MGMT PF) within the mlx5 driver. It involves updating the
mlx5 interface header to introduce necessary definitions for MGMT PF
and adding a new management PF netdev profile, which will allow the host
side to communicate with the embedded linux on Blue-field devices.

crc_ccitt_false() was introduced in commit 0d85adb5fbd33 ("lib/crc-ccitt:

Since the latter is more used, it is the one being kept.

User space can change the weight of a thermal instance via sysfs while the
.throttle() callback is running for a governor, because weight_store()
does not use the zone lock.
The IPA governor uses instance weight values for power calculations and
caches the sum of them as total_weight, so it gets confused when one of
them changes while its .throttle() callback is running.
To prevent that from happening, use thermal zone locking in
weight_store().

Add a new callback to the struct thermal_governor. It can be used for
updating governors when there is a change in the thermal zone internals,
e.g. thermal cooling device is bind to the thermal zone.
That makes possible to move some heavy operations like memory allocations
related to the number of cooling instances out of the throttle() callback.
Both callback code paths (throttle() and update_tz()) are protected with
the same thermal zone lock, which guaranties the consistency.

Commit 804951203aa5 ("platform/x86:intel/pmc: Combine core_init() and
core_configure()") caused a network performance regression due to the GBE
LTR ignore that it added at probe. This was needed in order to allow the
SoC to enter the deepest Package C state. To fix the regression and at
least support PC10 during suspend, move the LTR ignore from probe to the
suspend callback, and enable it again on resume. This solution will allow
PC10 during suspend but restrict Package C entry at runtime to no deeper
than PC8/9 while a network cable it attach to the PCH LAN.

p2sb_bar() unhides P2SB device to get resources from the device. It
guards the operation by locking pci_rescan_remove_lock so that parallel
rescans do not find the P2SB device. However, this lock causes deadlock
when PCI bus rescan is triggered by /sys/bus/pci/rescan. The rescan
locks pci_rescan_remove_lock and probes PCI devices. When PCI devices
call p2sb_bar() during probe, it locks pci_rescan_remove_lock again.
Hence the deadlock.
To avoid the deadlock, do not lock pci_rescan_remove_lock in p2sb_bar().
Instead, do the lock at fs_initcall. Introduce p2sb_cache_resources()
for fs_initcall which gets and caches the P2SB resources. At p2sb_bar(),
refer the cache and return to the caller.

Expose through debugfs device telemetry data for QAT GEN4 devices.
This allows to gather metrics about the performance and the utilization
of a device. In particular, statistics on (1) the utilization of the
PCIe channel, (2) address translation, when SVA is enabled and (3) the
internal engines for crypto and data compression.
If telemetry is supported by the firmware, the driver allocates a DMA
region and a circular buffer. When telemetry is enabled, through the
`control` attribute in debugfs, the driver sends to the firmware, via
the admin interface, the `TL_START` command. This triggers the device to
periodically gather telemetry data from hardware registers and write it
into the DMA memory region. The device writes into the shared region
every second.
The driver, every 500ms, snapshots the DMA shared region into the
circular buffer. This is then used to compute basic metric
(min/max/average) on each counter, every time the `device_data` attribute
is queried.
Telemetry counters are exposed through debugfs in the folder
/sys/kernel/debug/qat_<device>_<BDF>/telemetry.

Extend the admin interface with two new public APIs to enable

adf_send_admin_tl_stop().
The first, sends to the firmware, through the ICP_QAT_FW_TL_START
message, the IO address where the firmware will write telemetry
metrics and a list of ring pairs (maximum 4) to be monitored.
It returns the number of accelerators of each type supported by
this hardware. After this message is sent, the firmware starts
periodically reporting telemetry data using by writing into the
dma buffer specified as input.
The second, sends the admin message ICP_QAT_FW_TL_STOP
which stops the reporting of telemetry data.
