The following debug output was observed while testing CXL
cxl_core:cxl_walk_cel:721: cxl_mock_mem cxl_mem.0: Opcode 0x4300 unsupported by driver
opcode 0x4300 (Get Poison) is supported by the driver and the mock
device supports it. The logic should be checking that the opcode is
both not poison and not security.
Fix the logic to allow poison and security commands.

Some devices are reporting controller ready mode support, but return 0
for CRTO. These devices require a much higher time to ready than that,
so they are failing to initialize after the driver starter preferring
that value over CAP.TO.
The spec requires that CAP.TO match the appropritate CRTO value, or be
set to 0xff if CRTO is larger than that. This means that CAP.TO can be
used to validate if CRTO is reliable, and provides an appropriate
fallback for setting the timeout value if not. Use whichever is larger.

Commit bc840ea5f9a9 ("thermal: core: Do not handle trip points with
invalid temperature") added a check for invalid temperature to the
disabled trip point check in handle_thermal_trip(), but that check was
added at a point when the trip structure has not been initialized yet.
This may cause handle_thermal_trip() to skip a valid trip point in some
cases, so fix it by moving the check to a suitable place, after
__thermal_zone_get_trip() has been called to populate the trip
structure.

If there are multiple arrays in system and one mddevice is marked
with MD_DELETED and md_seq_next() is called in the middle of removal
then it _get()s proper device but it may _put() deleted one. As a result,
active counter may never be zeroed for mddevice and it cannot
be removed.

There's a race condition in the multipath target when retrieve_deps
races with multipath_message calling dm_get_device and dm_put_device.
retrieve_deps walks the list of open devices without holding any lock
but multipath may add or remove devices to the list while it is
running. The end result may be memory corruption or use-after-free
memory access.
See this description of a UAF with multipath_message():
https://listman.redhat.com/archives/dm-devel/2022-October/052373.html
Fix this bug by introducing a new rw semaphore "devices_lock". We grab
devices_lock for read in retrieve_deps and we grab it for write in
dm_get_device and dm_put_device.

This is based on alx driver commit 881d0327db37 ("net: alx: Work around
the DMA RX overflow issue").
The alx and atl1c drivers had RX overflow error which was why a custom
allocator was created to avoid certain addresses. The simpler workaround
then created for alx driver, but not for atl1c due to lack of tester.
Instead of using a custom allocator, check the allocated skb address and
use skb_reserve() to move away from problematic 0x...fc0 address.
Tested on AR8131 on Acer 4540.

During rmmod, when dev_loss_tmo callback is called, an ndlp kref count is
decremented twice. Once for SCSI transport registration and second to
remove the initial node allocation kref. If there is also an NVMe
transport registration, another reference count decrement is expected in
lpfc_nvme_unregister_port().
Race conditions between the NVMe transport remoteport_delete and
dev_loss_tmo callbacks sometimes results in premature ndlp object release
resulting in use-after-free issues.
Fix by not dropping the ndlp object in dev_loss_tmo callback with an
outstanding NVMe transport registration. Inversely, mark the final
NLP_DROPPED flag in lpfc_nvme_unregister_port when rmmod flag is set.

When a dev_loss_tmo event occurs, an ndlp lock is taken before checking
nlp_flag for NLP_DROPPED. There is an attempt to restore the ndlp lock
when exiting the if statement, but the nlp_put kref could be the final
decrement causing a use-after-free memory access on a released ndlp object.
Instead of trying to reacquire the ndlp lock after checking nlp_flag, just
return after calling nlp_put.

The function pm8001_pci_resume() only calls pm8001_request_irq() without
calling pm8001_setup_irq(). This causes the IRQ allocation to fail, which
leads all drives being removed from the system.
Fix this issue by integrating the code for pm8001_setup_irq() directly
inside pm8001_request_irq() so that MSI-X setup is performed both during
normal initialization and resume operations.

Initialize all the ethtool ops that are supported by the driver and
add the necessary support for the ethtool callbacks. Also add
asynchronous link notification virtchnl support where the device
Control Plane sends the link status and link speed as an
asynchronous event message. Driver report the link speed on
ethtool .idpf_get_link_ksettings query.
Introduce soft reset function which is used by some of the ethtool
callbacks such as .set_channels, .set_ringparam etc. to change the
existing queue configuration. It deletes the existing queues by sending
delete queues virtchnl message to the CP and calls the 'vport_stop' flow
which disables the queues, vport etc. New set of queues are requested to
the CP and reconfigure the queue context by calling the 'vport_open'
flow. Soft reset flow also adjusts the number of vectors associated to a
vport if .set_channels is called.

Add support to handle interrupts for the RX completion queue and
RX buffer queue. When the interrupt fires on RX completion queue,
process the RX descriptors that are received. Allocate and prepare
the SKB with the RX packet info, for both data and header buffer.
IDPF uses software maintained refill queues to manage buffers between
RX queue producer and the buffer queue consumer. They are required in
order to maintain a lockless buffer management system and are strictly
software only constructs. Instead of updating the RX buffer queue tail
with available buffers right after the clean routine, it posts the
buffer ids to the refill queues, only to post them to the HW later.
If the generic receive offload (GRO) is enabled in the capabilities
and turned on by default or via ethtool, then HW performs the
packet coalescing if certain criteria are met by the incoming
packets and updates the RX descriptor. Similar to GRO, if generic
checksum is enabled, HW computes the checksum and updates the
respective fields in the descriptor. Add support to update the
SKB fields with the GRO and the generic checksum received.

Add support to handle the interrupts for the TX completion queue and
process the various completion types.
In the flow scheduling mode, the driver processes primarily buffer
completions as well as descriptor completions occasionally. This mode
supports out of order TX completions. To do so, HW generates one buffer
completion per packet. Each of those completions contains the unique tag
provided during the TX encoding which is used to locate the packet either
on the TX buffer ring or in a hash table. The hash table is used to track
TX buffer information so the descriptor(s) for a given packet can be
reused while the driver is still waiting on the buffer completion(s).
Packets end up in the hash table in one of 2 ways: 1) a packet was
stashed during descriptor completion cleaning, or 2) because an out of
order buffer completion was processed. A descriptor completion arrives
only every so often and is primarily used to guarantee the TX descriptor
ring can be reused without having to wait on the individual buffer
completions. E.g. a descriptor completion for N+16 guarantees HW read all
of the descriptors for packets N through N+15, therefore all of the
buffers for packets N through N+15 are stashed into the hash table and the
descriptors can be reused for more TX packets. Similarly, a packet can be
stashed in the hash table because an out an order buffer completion was
processed. E.g. processing a buffer completion for packet N+3 implies that
HW read all of the descriptors for packets N through N+3 and they can be
reused. However, the HW did not do the DMA yet. The buffers for packets N
through N+2 cannot be freed, so they are stashed in the hash table.
In either case, the buffer completions will eventually be processed for
all of the stashed packets, and all of the buffers will be cleaned from
the hash table.
In queue based scheduling mode, the driver processes primarily descriptor
completions and cleans the TX ring the conventional way.
Finally, the driver triggers a TX queue drain after sending the disable
queues virtchnl message. When the HW completes the queue draining, it
sends the driver a queue marker packet completion. The driver determines
when all TX queues have been drained and proceeds with the disable flow.
With this, the driver can send TX packets and clean up the resources
properly.

map the RX descriptor and buffer queues as well as TX completion
queues to the allocated vectors. Initialize and enable the napi
handler for the napi polling. Finally, request the IRQs for the

Once the interrupt init is done, send 'map queue vector', 'enable

Similar to the TX, RX also supports both single and split queue models.
In single queue model, the same descriptor queue is used by SW to post
buffer descriptors to HW and by HW to post completed descriptors
to SW. In split queue model, "RX buffer queues" are used to pass
descriptor buffers from SW to HW whereas "RX queues" are used to
post the descriptor completions i.e. descriptors that point to
completed buffers, from HW to SW. "RX queue group" is a set of
RX queues grouped together and will be serviced by a "RX buffer queue
group". IDPF supports 2 buffer queues i.e. large buffer (4KB) queue
and small buffer (2KB) queue per buffer queue group. HW uses large
buffers for 'hardware gro' feature and also if the packet size is
more than 2KB, if not 2KB buffers are used.
Add all the resources required for the RX queues initialization.
Allocate memory for the RX queue and RX buffer queue groups. Initialize
the software maintained refill queues for buffer management algorithm.
Same like the TX queues, initialize the queue parameters for the RX
queues and send the config RX queue virtchnl message to the device
Control Plane.

IDPF supports two queue models i.e. single queue which is a traditional
queueing model as well as split queue model. In single queue model,
the same descriptor queue is used by SW to post descriptors to the HW,
HW to post completed descriptors to SW. In split queue model, "TX Queues"
are used to pass buffers from SW to HW and "TX Completion Queues"
are used to post descriptor completions from HW to SW. Device supports
asymmetric ratio of TX queues to TX completion queues. Considering
this, queue group mechanism is used i.e. some TX queues are grouped
together which will be serviced by only one TX completion queue
per TX queue group.
Add all the resources required for the TX queues initialization.
To start with, allocate memory for the TX queue groups, TX queues and
TX completion queues. Then, allocate the descriptors for both TX and
TX completion queues, and bookkeeping buffers for TX queues alone.
Also, allocate queue vectors for the vport and initialize the TX queue
related fields for each queue vector.
Initialize the queue parameters such as q_id, q_type and tail register
offset with the info received from the device control plane (CP).
Once all the TX queues are configured, send config TX queue virtchnl
message to the CP with all the TX queue context information.

Virtchnl version 1 is an interface used by the current generation of
foundational NICs to negotiate the capabilities and configure the
HW resources such as queues, vectors, RSS LUT, etc between the PF
and VF drivers. It is not extensible to enable new features supported
in the next generation of NICs/IPUs and to negotiate descriptor types,
packet types and register offsets.
To overcome the limitations of the existing interface, introduce
the virtchnl version 2 and add the necessary opcodes, structures,
definitions, and descriptor formats. The driver also learns the
data queue and other register offsets to use instead of hardcoding
them. The advantage of this approach is that it gives the flexibility
to modify the register offsets if needed, restrict the use of
certain descriptor types and negotiate the supported packet types.

As discussed on LKML, using 'genpd' as the name of a subsystem isn't

Domain, is known only by a limited group of people.
The suggestion to improve the situation is to rename the subsystem to
'pmdomain', which there seems to be a good consensus around using.

Change the logging of each algorithm from info level to debug level.
On the original devices supported by this code there were typically only
one or two algorithms in a firmware and one or two DSPs so this logging
only used a small number of log lines.
However, for the latest devices there could be 30-40 algorithms in a
firmware and 8 DSPs being loaded in parallel, so using 300+ lines of log
