The change_work was introduced to send device change notifications
from DPLL device callbacks without deadlocking on dpll_lock, since
the callbacks are already invoked under that lock. Now that
__dpll_device_change_ntf() is exported for callers that already
hold dpll_lock, use it directly and remove the change_work
infrastructure entirely.
This eliminates a race condition where change_work could be
re-scheduled after cancel_work_sync() during device teardown,
potentially causing the handler to dereference a freed or NULL
dpll_dev pointer.

Export __dpll_device_change_ntf() so that drivers can send device
change notifications from within device callbacks, which are already
called under dpll_lock. Using dpll_device_change_ntf() in that
context would deadlock.
Add lockdep_assert_held() to catch misuse without the lock held.

Currently the code enqueue work items using {queue|mod}_delayed_work(),
using system_wq, which will be deprecated soon and replaced by
system_percpu_wq.
commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")
The function(s) mentioned earlier, end up calling __queue_delayed_work(),
which set a global timer that could fire anywhere, enqueuing the work
where the timer fired.
Unbound works could benefit from scheduler task placement, to optimize
performance and power consumption.
Since the workqueue work doesn't rely on per-cpu variables, there is no
obvious reason that justify the use of a per-cpu workqueue. So change
system_wq with system_dfl_wq so that the work may benefit from
scheduler task placement.

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.
This patch doesn't modify the compiled array, only its representation in
source form benefits. The former was confirmed with x86 and arm64

nvme_tcp_tls_done() assigns queue->tls_err in three branches. The
ENOKEY lookup failure and the EOPNOTSUPP initializer both store
negative errnos. The third branch, reached when the handshake
layer reports a non-zero status, stores -status.
The handshake layer delivers status to the consumer callback as a
negative errno; the other in-tree consumers --
xs_tls_handshake_done() and the nvmet target callback -- treat
their status argument that way. The extra negation in
nvme_tcp_tls_done() flips the sign, leaving tls_err as a positive
value (for instance, +EIO), which nvme_tcp_start_tls() then
returns to its caller.
Drop the extra negation so queue->tls_err uniformly carries a
negative errno on failure.

Currently AS SDP is only configured when VRR is enabled.
With optimized guardband, we also need to account for wakeup time and other
relevant details that depend on the AS SDP position whenever AS SDP is
enabled. If a feature enabling AS SDP gets turned on later (after modeset),
the guardband might not be sufficient and may need to increase, triggering
a full modeset.
Additionally, for Panel Replay with Aux-less ALPM where the sink does
not support asynchronous video timing in PR active, the source must
keep transmitting Adaptive-Sync SDPs while PR is active.
So, always send AS SDP whenever there is a possibility to use it for VRR
OR for Panel Replay for synchronization.
v2: Check if AS SDP can be used for synchronization for VRR or PR. (Ville)
v3: Use intel_psr_needs_alpm_aux_less() instead of

DP v2.1 allows the source to temporarily suspend Adaptive-Sync SDP
transmission while Panel Replay is active when the sink supports
asynchronous video timing.
In such cases, the sink relies on the last transmitted AS SDP timing
information to maintain the refresh rate. To support this behavior,
compute and populate the coasting vtotal field in the AS SDP payload.
Include coasting vtotal in AS SDP packing, unpacking, and comparison,
and set it during late AS SDP configuration for PR with Aux-less ALPM
when asynchronous video timing is supported.
Note:
The coasting vtotal value is fully under driver control i.e. the HW does
not overwrite these payload bytes. HW only samples the PR_ALPM_CTL[AS SDP
Transmission in Active Disable] bit during PR active state and reflects it
in the AS SDP payload at the appropriate time.

If a Panel Replay capable sink, supports Async Video timing in
PR active state, then source does not necessarily need to send AS SDPs
during PR active.
However, if asynchronous video timing is not supported, then for PR with
Aux-less ALPM, the source must transmit Adaptive-Sync SDPs for video
timing synchronization while PR is active.
If the source needs to send AS SDP during PR active, this requires setting
DPCD 0x0107[6] (FIXED_VTOTAL_AS_SDP_EN_IN_PR_ACTIVE). This applies whether
VRR is enabled (AVT/FAVT) or fixed-timing mode is used.
This bit defines AS SDP timing behavior during PR Active, even if AS SDPs
are briefly suspended.
Program the relevant Downspread Ctrl DPCD bits accordingly.
v2: Instead of Panel Replay check simply use AS SDP enable check. (Ville)
v3: Since the bit is defined in context of Panel Replay and AS SDP, add
a check for both. (Ville)

eDP v1.5a advertises support for Adaptive Sync SDP and with that the
support for AS SDP v2 is mandatory.
DP v2.1 SCR advertises support for FAVT payload fields parsing in DPCD
0x2214 Bit 2. This indicates the support for Adaptive-Sync SDP version 2
(AS SDP v2), which allows the source to set the version in HB2[4:0] and the
payload length in HB3[5:0] of the AS SDP header.
DP v2.1 SCR also introduces ASYNC_VIDEO_TIMING_NOT_SUPPORTED_IN_PR in the
Panel Replay Capability DPCD 0x00b1 (Bit 3). When this bit is set, the sink
does not support asynchronous video timing while in a Panel Replay Active
state and the source is required to keep transmitting Adaptive-Sync
SDPs. The spec mandates that such sinks shall support AS SDP v2.
Infer AS SDP v2 support from these capabilities and store it in
struct intel_dp for use by subsequent feature enablement changes.

- Include parsing ASYNC_VIDEO_TIMING_NOT_SUPPORTED_IN_PR bit to
determine AS SDP v2 support. (Ville)
v3:
- Use helper to determine asynch video timing support.
v4:
- Add AS SDP v2 support for eDP as per v1.5a.

The Lenovo GameZone/Other interfaces have some delicate divergences
among different devices. When making a bug report or adding support for
new devices/interfaces, capdata is the most important information to
cross-check with.
Add a debugfs file (lenovo_wmi/<device_name>/capdata), so that users can
dump capdata and include it in their reports.
Since `struct capdata01' is just an extension to `struct capdata00',
also convert the former to include the latter anonymously
(-fms-extensions, since v6.19). This is declared as a union in the
capdata01 struct, with both the anonymous declaration and as a named
member to avoid type casting when passing just the capdata00 struct
pointer.

Some Lenovo BIOS have been shown to have incomplete and/or broken
capability data and WMI attribute IDs. In some cases the capability data
reports that a feature is not supported when the get/set methods are
fully implemented. It is also possible that the ACPI methods from the
ideapad_laptop driver we defer to could be bugged while the WMI method
is fully working. To aid end users in submitting more complete bug
reports in these situations, add an override to skip the ACPI and
compatibility checks to force load the power supply extension as if it
is fully supported and has no conflicts.

Add charge_behaviour and charge_types attributes through a power supply
extension for devices that support WMI based charge enable & disable.
Lenovo Legion devices that implement WMI function and capdata ID
0x03010001 in their BIOS are able to enable or disable charging at 80%
through the lenovo-wmi-other interface. Add a charge_types attribute for
BATX devices to expose this capability with Standard and Long_Life types
enabled.
Additionally, devices that support WMI function and capdata ID 0x03020000
are able to force discharge of the battery. Expose this capability with
a charge_behaviour attribute in the power supply extension, with the auto
and force-discharge behaviors enabled. The GET method for this attribute
is bugged. After analyzing the DSDT, and some testing, it appears the
method grabs bit(3) instead of bit(4) from the EC register that stores the
current status, and will only report if charging has been inhibited or
not. To work around this, store and report the last setting written to the
attribute.
As some devices only expose one attribute or the other, a bitmask is
added with a lookup table and some helper macros to select the correct
configuration for the hardware at runtime.
The ideapad_laptop driver provides the charge_types attribute to provide
similar functionality. When the WMI method is set this can corrupt the
ACPI method return and cause hardware and driver errors. To avoid
conflicts between the drivers, we get the acpi_handle and do the same
check that ideapad_laptop does when it enables the feature. If the
feature is supported in ideapad_laptop, abort adding the extension from
lenovo-wmi-other. The ACPI method is more reliable when both are
present from my testing, so we can prefer that implementation and do
not need to worry about de-conflicting from inside that driver.

The dma_rmb() barrier was placed before dma_sync_single_for_cpu(), which
is incorrect. DMA sync must complete first to make the buffer accessible
to the CPU, then the rmb barrier ensures subsequent descriptor reads
observe the latest data written by the hardware.
Reorder the operations so dma_sync_single_for_cpu() is called before
dma_rmb() to guarantee the driver reads consistent data from the DMA

xd->state_work via queue_delayed_work() in three request handlers:
PROPERTIES_CHANGED_REQUEST, UUID_REQUEST (via start_handshake),
and LINK_STATE_CHANGE_REQUEST. Similarly, update_xdomain() queues
xd->properties_changed_work when local properties change.
Concurrently, tb_xdomain_remove() calls stop_handshake() which does
cancel_delayed_work_sync() on both delayed works. Later,
tb_xdomain_unregister() calls device_unregister() which eventually
frees the xdomain. Since commit 559c1e1e0134 ("thunderbolt: Run
tb_xdp_handle_request() in system workqueue") moved the request
handler off tb->wq, the handler and the remove path are no longer
serialized. If queue_delayed_work() executes after
cancel_delayed_work_sync() but before the xdomain is freed, the
delayed work fires on a freed object.
Add xd->removing that tb_xdomain_remove() sets under xd->lock
before calling stop_handshake(). Each external queue site holds
the same lock and checks removing before calling
queue_delayed_work(). This provides the mutual exclusion needed:
either the queue site acquires the lock first and queues work that
the subsequent cancel will see, or the remove path acquires the
lock first and the queue site observes removing == true and skips
the queue.

Convert to use test_and_clear_bit() for link event subtasks. Only re-arm
the WX_FLAG_NEED_MODULE_RESET flag when module is absent. Unsupported or
invalid modules no longer cause the service task to continuously retry
module identification.
Additionally, explicitly cancel service_task during device teardown to
ensure no pending asynchronous service work survives after the device
has entered the DOWN state.

After introducing WX_STATE_DOWN, wx_update_stats() now explicitly skips
statistics collection while the device is in teardown or reset state.
Calling wx_update_stats() from the device disable path therefore becomes
redundant.
Remove wx_update_stats() calls from ngbe_disable_device() and
txgbe_disable_device().

Replace various netif_running() checks with an explicit WX_STATE_DOWN
state bit to track whether the device datapath and interrupt handling
are operational.
The previous logic relied on netif_running() to gate interrupt
reenablement, queue wakeups, statistics updates, and service task
execution. However, netif_running() only reflects the administrative
state of the netdevice and does not fully serialize against teardown
and reset paths. During device shutdown and reset flows, asynchronous
contexts such as interrupt handlers, NAPI poll, and service work could
still observe netif_running() as true while device resources were
already being disabled or freed.

mac80211_hwsim_sta_rc_update() is unable to handle S1G widths so
when a new STA is added under a S1G vif the WARN is hit preventing
hwsim use for S1G. For now, skip calling rc_update() for S1G
interfaces. This is required such that the soon-to-be S1G hwsim tests
can successfully run.
