It can also enabled and disable this SDP as needed without a full

So here masking DP_SDP_VSC bit when previous and future state PSR

Commit 78b772e1a01f ("drm/i915/display: Fill PSR state during hardware
configuration read out") is not allowing fastsets to happen when PSR
states changes but PSR is a feature that can be enabled and disabled
during fastsets.
So here moving the PSR pipe conf checks to a block that is only
executed when checking if HW state matches with requested state, not
during the phase where it checks if fastset is possible or not.
There still a state mismatch not allowing fastsets between states
turning off or on PSR because of crtc_state->infoframes.enable
BIT(DP_SDP_VSC) but at least for now it will allow a fastset between
PSR1 <-> PSR2, that is a case heavilly used by CI due to pipe CRC not
work with PSR2, but the remaning issue will be fixed in a future patch.

After performing a flash update, a device EMP reset may occur. This
reset will cause the newly downloaded firmware to be initialized. When
this happens, the driver still reports the previous NVM version
information.
This is because the NVM versions are cached within the hw structure.
This can be confusing, as the new firmware is in fact running in this
case.
Handle this by calling ice_init_nvm when rebuilding the driver state.
This will update the flash version information and ensures that the
current values are displayed when reporting the NVM versions to the
stack.

Requesting device firmware information while the device is busy cleaning
up after a reset can result in an unexpected failure:
This occurs because the command is attempting to access the device
AdminQ while it is down. Resolve this by having the command wait for
a while until the reset is complete. To do this, introduce
a reset_wait_queue and associated helper function "ice_wait_for_reset".
This helper will use the wait queue to sleep until the driver is done
rebuilding. Use of a wait queue is preferred because the potential sleep
duration can be several seconds.
To ensure that the thread wakes up properly, a new wake_up call is added
during all code paths which clear the reset state bits associated with
the driver rebuild flow.
Using this ensures that tools can request device information without
worrying about whether the driver is cleaning up from a reset.
Specifically, it is expected that a flash update could result in
a device reset, and it is better to delay the response for information
until the reset is complete rather than exit with an immediate failure.

When flashing a new firmware image onto the device, the pldmfw library
parses the image contents looking for a matching record. If no record
can be found, the function reports an error of -ENOENT. This can produce
a very confusing error message and experience for the user:
$devlink dev flash pci/0000:ab:00.0 file image.bin
devlink answers: No such file or directory
This is because the ENOENT error code is interpreted as a missing file
or directory. The pldmfw library does not have direct access to the
extack pointer as it is generic and non-netdevice specific. The only way
that ENOENT is returned by the pldmfw library is when no record matches.
Catch this specific error and report a suitable extended ack message:
$devlink dev flash pci/0000:ab:00.0 file image.bin
Error: ice: Firmware image has no record matching this device
devlink answers: No such file or directory
In addition, ensure that we log an error message to the console whenever
this function fails. Because our driver specific PLDM operation
functions potentially set the extended ACK message, avoid overwriting
this with a generic message.
This change should result in an improved experience when attempting to
flash an image that does not have a compatible record.

Currently, when a VF requests queue configuration via
VIRTCHNL_OP_CONFIG_VSI_QUEUES the PF driver expects that this message
will only be called once and we always assume the queues being
configured start from 0. This is incorrect and is causing issues when
a VF tries to send this message for multiple queue blocks. Fix this by
using the queue_id specified in the virtchnl message and allowing for
individual Rx and/or Tx queues to be configured.
Also, reduce the duplicated for loops for configuring the queues by
moving all the logic into a single for loop.

If a VM reboots and/or VF driver is unloaded, its cached hardware MAC
address (hw_lan_addr.addr) is cleared in some cases. If the VF is
trusted, then the PF driver allows the VF to clear its old MAC address
even if this MAC was configured by a host administrator. If the VF is
untrusted, then the PF driver allows the VF to clear its old MAC
address only if the host admin did not set it.
For the trusted VF case, this is unexpected and will cause issues
because the host configured MAC (i.e. via XML) will be cleared on VM
reboot. For the untrusted VF case, this is done to be consistent and it
will allow the VF to keep the same MAC across VM reboot.
Fix this by introducing dev_lan_addr to the VF structure. This will be
the VF's MAC address when it's up and running and in most cases will be
the same as the hw_lan_addr. However, to address the VM reboot and
unload/reload problem, the driver will never allow the hw_lan_addr to be
cleared via VIRTCHNL_OP_DEL_ETH_ADDR. When the VF's MAC is changed, the
dev_lan_addr and hw_lan_addr will always be updated with the same value.
The only ways the VF's MAC can change are the following:
- Set the VF's MAC administratively on the host via iproute2.
- If the VF is trusted and changes/sets its own MAC.
- If the VF is untrusted and the host has not set the MAC via iproute2.

Currently there is no way for a VF driver to specify if it wants to
change it's hardware address. New bits are being added to virtchnl.h
in struct virtchnl_ether_addr that allow for the VF to correctly
communicate this information. However, legacy VF drivers that don't
support the new virtchnl.h bits still need to be supported. Make a
best effort attempt at saving the VF's primary/device address in the
legacy case and depend on the VIRTCHNL_ETHER_ADDR_PRIMARY type for
the new case.
Legacy case - If a unicast MAC is being added and the
hw_lan_addr.addr is empty, then populate it. This assumes that the
address is the VF's hardware address. If a unicast MAC is being
added and the hw_lan_addr.addr is not empty, then cache it in the
legacy_last_added_umac.addr. If a unicast MAC is being deleted and it
matches the hw_lan_addr.addr, then zero the hw_lan_addr.addr.
Also, if the legacy_last_added_umac.addr has not expired, copy the
legacy_last_added_umac.addr into the hw_lan_addr.addr. This is done
because we cannot guarantee the order of VIRTCHNL_OP_ADD_ETH_ADDR and
VIRTCHNL_OP_DEL_ETH_ADDR.
New case - If a unicast MAC is being added and it's specified as
VIRTCHNL_ETHER_ADDR_PRIMARY, then replace the current
hw_lan_addr.addr. If a unicast MAC is being deleted and it's type
is specified as VIRTCHNL_ETHER_ADDR_PRIMARY, then zero the
hw_lan_addr.addr.
Untrusted VFs - Only allow above legacy/new changes to their
hardware address if the PF has not set it administratively via
iproute2.
Trusted VFs - Always allow above legacy/new changes to their
hardware address even if the PF has administratively set it via
iproute2.
Also, change the variable dflt_lan_addr to hw_lan_addr to clearly
represent the purpose of this variable since it's purpose is to
act as a hardware programmed MAC address for the VF.

In some ACPI tables we encounter, devices use the _DEP method to assert
a dependence on other ACPI devices as opposed to the OpRegions that the
specification intends.
We need to be able to find those devices "from" the dependee, so add
a callback and a wrapper to walk over the acpi_dep_list and return
the dependent ACPI device.
