Existing last step of dsc policy is to restore pbn value under minimum compression
when try to greedily disable dsc for a stream failed to fit in MST bw.
Optimized dsc params result from optimization step is not necessarily the minimum compression,
therefore it is not correct to restore the pbn under minimum compression rate.
Restore the pbn under minimum compression instead of the value from optimized pbn could result
in the dsc params not correct at the modeset where atomic_check failed due to not
enough bw. One or more monitors connected could not light up in such case.
Restore the optimized pbn value, instead of using the pbn value under minimum
compression.

Dell All In One (AIO) models released after 2017 may use a backlight
controller board connected to an UART.
In DSDT this uart port will be defined as:
Name (_HID, "DELL0501")
Name (_CID, EisaId ("PNP0501")
The Dell OptiPlex 5480 AIO has an ACPI device for one of its UARTs with
the above _HID + _CID. Loading the dell-uart-backlight driver fails with
the following errors:
[ 18.261353] dell_uart_backlight serial0-0: Timed out waiting for response.
[ 18.261356] dell_uart_backlight serial0-0: error -ETIMEDOUT: getting firmware version
[ 18.261359] dell_uart_backlight serial0-0: probe with driver dell_uart_backlight failed with error -110
Indicating that there is no backlight controller board attached to
the UART, while the GPU's native backlight control method does work.
Add a quirk to use the GPU's native backlight control method on this model.

notify_hwp_interrupt() is called via sysvec_thermal() ->
smp_thermal_vector() -> intel_thermal_interrupt() in hard irq context.
For this reason it must not use a simple spin_lock that sleeps with
PREEMPT_RT enabled. So convert it to a raw spinlock.

When nvme passthru is configured using loop target, the clear_ids
attribute is, by default, set to true. This attribute would ensure that
EUID/NGUID/UUID is cleared for the loop passthru target.
The newer NVMe disk supporting the NVMe spec 1.3 or higher, typically,
implements the support for "Namespace Identification Descriptor list"
command. This command when issued from host returns EUID/NGUID/UUID
assigned to the inquired namespace. Not clearing these values, while
using nvme passthru using loop target, would result in NVMe host driver
rejecting the namespace. This check was implemented in the commit
2079f41ec6ff ("nvme: check that EUI/GUID/UUID are globally unique").
The fix implemented in this commit ensure that when host issues ns-id
descriptor list command, the EUID/NGUID/UUID are cleared by passthru
target. In fact, the function nvmet_passthru_override_id_descs() which
clears those unique ids already exits, so we just need to ensure that
ns-id descriptor list command falls through the corretc code path. And
while we're at it, we also combines the three passthru admin command
cases together which shares the same code.

The only user (the mesa gallium driver) is already assuming explicit
synchronization and doing the export/import dance on shared BOs. The
only reason we were registering ourselves as writers on external BOs
is because Xe, which was the reference back when we developed Panthor,
was doing so. Turns out Xe was wrong, and we really want bookkeep on
all registered fences, so userspace can explicitly upgrade those to
read/write when needed.

If deferred operations are pending, we want to wait for those to
land before declaring the queue blocked on a SYNC_WAIT. We need
this to deal with the case where the sync object is signalled through
a deferred SYNC_{ADD,SET} from the same queue. If we don't do that
and the group gets scheduled out before the deferred SYNC_{SET,ADD}
is executed, we'll end up with a timeout, because no external
SYNC_{SET,ADD} will make the scheduler reconsider the group for
execution.

In case there is any sort of clock controller attached to this I2C bus
controller, for example Versaclock or even an AIC32x4 I2C codec, then
an I2C transfer triggered from the clock controller clk_ops .prepare
callback may trigger a deadlock on drivers/clk/clk.c prepare_lock mutex.
This is because the clock controller first grabs the prepare_lock mutex
and then performs the prepare operation, including its I2C access. The
I2C access resumes this I2C bus controller via .runtime_resume callback,
which calls clk_prepare_enable(), which attempts to grab the prepare_lock
mutex again and deadlocks.
Since the clock are already prepared since probe() and unprepared in
remove(), use simple clk_enable()/clk_disable() calls to enable and
disable the clock on runtime suspend and resume, to avoid hitting the
prepare_lock mutex.

When applying padding, the buffer is not zeroed, which results in memory
disclosure. The mentioned data is observed on the wire. This patch uses
skb_put_padto() to pad Ethernet frames properly. The mentioned function
zeroes the expanded buffer.
In case the packet cannot be padded it is silently dropped. Statistics
are also not incremented. This driver does not support statistics in the
old 32-bit format or the new 64-bit format. These will be added in the
future. In its current form, the patch should be easily backported to
stable versions.
Ethernet MACs on Amazon-SE and Danube cannot do padding of the packets
in hardware, so software padding must be applied.

CONFIG_DRM_I915_USERFAULT_AUTOSUSPEND is an int, defaulting to 250. When
the wakeref is non-zero, it's either -1 or a dynamically allocated
pointer, depending on CONFIG_DRM_I915_DEBUG_RUNTIME_PM. It's likely that
the code works by coincidence with the bitwise AND, but with
CONFIG_DRM_I915_DEBUG_RUNTIME_PM=y, there's the off chance that the
condition evaluates to false, and intel_wakeref_auto() doesn't get
called. Switch to the intended logical AND.

When the device is removed, idpf is supposed to make certain virtchnl
requests e.g. VIRTCHNL2_OP_DEALLOC_VECTORS and VIRTCHNL2_OP_DESTROY_VPORT.
However, this does not happen due to the referenced commit introducing
virtchnl transaction manager and placing its deinitialization before those
messages are sent. Then the sending is impossible due to no transactions
being available.
Lack of cleanup can lead to the FW becoming unresponsive from e.g.
unloading-loading the driver and creating-destroying VFs afterwards.
Move transaction manager deinitialization to after other virtchnl-related
cleanup is done.

When a mailbox message is received, the driver is checking for a non 0
datalen in the controlq descriptor. If it is valid, the payload is
attached to the ctlq message to give to the upper layer. However, the
payload response size given to the upper layer was taken from the buffer
metadata which is _always_ the max buffer size. This meant the API was
returning 4K as the payload size for all messages. This went unnoticed
since the virtchnl exchange response logic was checking for a response
size less than 0 (error), not less than exact size, or not greater than
or equal to the max mailbox buffer size (4K). All of these checks will
pass in the success case since the size provided is always 4K. However,
this breaks anyone that wants to validate the exact response size.
Fetch the actual payload length from the value provided in the
descriptor data_len field (instead of the buffer metadata).
Unfortunately, this means we lose some extra error parsing for variable
sized virtchnl responses such as create vport and get ptypes. However,
the original checks weren't really helping anyways since the size was
_always_ 4K.

There is a bug currently when there are more than one VLAN defined
and any reset that affects the PF is initiated, after the reset rebuild
no traffic will pass on any VLAN but the last one created.
This is caused by the iteration though the VLANs during replay each
clearing the vsi_map bitmap of the VSI that is being replayed. The
problem is that during rhe replay, the pointer to the vsi_map bitmap
is used by each successive vlan to determine if it should be replayed
on this VSI.
The logic was that the replay of the VLAN would replace the bit in the map
before the next VLAN would iterate through. But, since the replay copies
the old bitmap pointer to filt_replay_rules and creates a new one for the
recreated VLANS, it does not do this, and leaves the old bitmap broken
to be used to replay the remaining VLANs.
Since the old bitmap will be cleaned up in post replay cleanup, there is
no need to alter it and break following VLAN replay, so don't clear the
bit.

Currently the user may request DPLL_PIN_STATE_SELECTABLE for an output
pin, and this would actually set the DISCONNECTED state instead.
It doesn't make any sense. SELECTABLE is valid only in case of input pins
(on AUTOMATIC type dpll), where dpll itself would select best valid input.
For the output pin only CONNECTED/DISCONNECTED are expected.

Since commit 2a2cb4c6c181 ("ice: replace ice_vf_recreate_vsi() with
ice_vf_reconfig_vsi()") VF VSI is only reconfigured instead of
recreated. The context configuration from previous setting is still the
same. If any of the config needs to be cleared it needs to be cleared
explicitly.
Previously there was assumption that port vlan will be cleared
automatically. Now, when VSI is only reconfigured we have to do it in the
code.
Not clearing port vlan configuration leads to situation when the driver
VSI config is different than the VSI config in HW. Traffic can't be
passed after setting and clearing port vlan, because of invalid VSI
config in HW.
Example reproduction:
> ip a a dev $(VF) $(VF_IP_ADDRESS)
> ip l s dev $(VF) up
> ping $(VF_IP_ADDRESS)
ping is working fine here
> ip link set eth5 vf 0 vlan 100
> ip link set eth5 vf 0 vlan 0
> ping $(VF_IP_ADDRESS)
ping isn't working

This patch addresses an issue with improper reference count handling in the
ice_sriov_set_msix_vec_count() function.
First, the function calls ice_get_vf_by_id(), which increments the
reference count of the vf pointer. If the subsequent call to
ice_get_vf_vsi() fails, the function currently returns an error without
decrementing the reference count of the vf pointer, leading to a reference
count leak. The correct behavior, as implemented in this patch, is to
decrement the reference count using ice_put_vf(vf) before returning an
error when vsi is NULL.
Second, the function calls ice_sriov_get_irqs(), which sets
vf->first_vector_idx. If this call returns a negative value, indicating an
error, the function returns an error without decrementing the reference
count of the vf pointer, resulting in another reference count leak. The
patch addresses this by adding a call to ice_put_vf(vf) before returning
an error when vf->first_vector_idx < 0.
This bug was identified by an experimental static analysis tool developed
by our team. The tool specializes in analyzing reference count operations
and identifying potential mismanagement of reference counts. In this case,
the tool flagged the missing decrement operation as a potential issue,
leading to this patch.

This patch addresses a reference count handling issue in the
ice_dpll_init_rclk_pins() function. The function calls ice_dpll_get_pins(),
which increments the reference count of the relevant resources. However,
if the condition WARN_ON((!vsi || !vsi->netdev)) is met, the function
currently returns an error without properly releasing the resources
acquired by ice_dpll_get_pins(), leading to a reference count leak.
To resolve this, the check has been moved to the top of the function. This
ensures that the function verifies the state before any resources are
acquired, avoiding the need for additional resource management in the
error path.
This bug was identified by an experimental static analysis tool developed
by our team. The tool specializes in analyzing reference count operations
and detecting potential issues where resources are not properly managed.
In this case, the tool flagged the missing release operation as a
potential problem, which led to the development of this patch.

The filters set that will reproduce the problem:
$ tc filter add dev $VF0_PR ingress protocol arp prio 0 flower \
skip_sw dst_mac ff:ff:ff:ff:ff:ff action mirred egress \
redirect dev $PF0
$ tc filter add dev $VF0_PR ingress protocol arp prio 0 flower \
skip_sw dst_mac ff:ff:ff:ff:ff:ff src_mac 52:54:00:00:00:10 \
action mirred egress mirror dev $VF1_PR
Expected behaviour is to set all broadcast from VF0 to the LAN. If the
src_mac match the value from filters, send packet to LAN and to VF1.
In this case both LAN_EN and LB_EN flags in switch is set in case of
packet matching both filters. As dst VSI for the only LAN enable bit is
PF VSI, the packet is being seen on PF. To fix this change dst VSI to
the source VSI. It will block receiving any packet even when LB_EN is
set by switch, because local loopback is clear on VF VSI during normal
operation.
Side note: if the second filters action is redirect instead of mirror
LAN_EN is clear, because switch is AND-ing LAN_EN from each matched
filters and OR-ing LB_EN.

The SBDF of the target CXL 2.0 compliant root port is required to inject a CXL
protocol error as per ACPI 6.5. The SBDF given has to be in the
following format:
31 24 23 16 15 11 10 8 7 0
+-------------------------------------------------+
| segment | bus | device | function | reserved |
+-------------------------------------------------+
The SBDF calculated in cxl_dport_get_sbdf() doesn't account for
the reserved bits currently, causing the wrong SBDF to be used.
Fix said calculation to properly shift the SBDF.
Without this fix, error injection into CXL 2.0 root ports through the
CXL debugfs interface (<debugfs>/cxl) is broken. Injection
through the legacy interface (<debugfs>/apei/einj/) will still work
because the SBDF is manually provided by the user.
