The AMD P-State driver is based on ACPI CPPC function, so ACPI should be
dependence of this driver in the kernel config.

The spaceball.c module was not properly parsing the movement reports
coming from the device. The code read axis data as signed 16-bit
little-endian values starting at offset 2.
In fact, axis data in Spaceball movement reports are signed 16-bit
big-endian values starting at offset 3. This was determined first by
visually inspecting the data packets, and later verified by consulting:

Syzbot has reported warning in __flush_work(). This warning is caused by
work->func == NULL, which means missing work initialization.
This may happen, since input_dev->close() calls
cancel_work_sync(&dev->work), but dev->work initalization happens _after_
input_register_device() call.
So this patch moves dev->work initialization before registering input
device

Pull drm fixes from Dave Airlie:
"This is a bit bigger than I'd like, however it has two weeks of amdgpu
fixes in it, since they missed last week, which was very small.
The nouveau regression is probably the biggest fix in here, and it
needs to go into 5.15 as well, two i915 fixes, and then a scattering
of amdgpu fixes. The biggest fix in there is for a fencing NULL
pointer dereference, the rest are pretty minor.
For the misc team, I've pulled the two misc fixes manually since I'm
not sure what is happening at this time of year!
The amdgpu maintainers have the outstanding runpm regression to fix
still, they are just working through the last bits of it now.

memory solution
In some of Zen2 and Zen3 based processors, they are using the shared
memory that exposed from ACPI SBIOS. In this kind of the processors,
there is no MSR support, so we add acpi cppc function as the backend for
them.
It is using a module param (shared_mem) to enable related processors
manually. We will enable this by default once we address performance
issue on this solution.

processors
AMD P-State is the AMD CPU performance scaling driver that introduces a
new CPU frequency control mechanism on AMD Zen based CPU series in Linux
kernel. The new mechanism is based on Collaborative processor
performance control (CPPC) which is finer grain frequency management
than legacy ACPI hardware P-States. Current AMD CPU platforms are using
the ACPI P-states driver to manage CPU frequency and clocks with
switching only in 3 P-states. AMD P-State is to replace the ACPI
P-states controls, allows a flexible, low-latency interface for the
Linux kernel to directly communicate the performance hints to hardware.
AMD P-State leverages the Linux kernel governors such as *schedutil*,
*ondemand*, etc. to manage the performance hints which are provided by CPPC
hardware functionality. The first version for AMD P-State is to support one
of the Zen3 processors, and we will support more in future after we verify
the hardware and SBIOS functionalities.
There are two types of hardware implementations for AMD P-State: one is full
MSR support and another is shared memory support. It can use
X86_FEATURE_CPPC feature flag to distinguish the different types.
Using the new AMD P-State method + kernel governors (*schedutil*,
*ondemand*, ...) to manage the frequency update is the most appropriate
bridge between AMD Zen based hardware processor and Linux kernel, the
processor is able to adjust to the most efficiency frequency according to
the kernel scheduler loading.

Add a new function to enable CPPC feature. This function
will write Continuous Performance Control package
EnableRegister field on the processor.
CPPC EnableRegister register described in section 8.4.7.1 of ACPI 6.4:
This element is optional. If supported, contains a resource descriptor
with a single Register() descriptor that describes a register to which
OSPM writes a One to enable CPPC on this processor. Before this register
is set, the processor will be controlled by legacy mechanisms (ACPI
Pstates, firmware, etc.).
This register will be used for AMD processors to enable AMD P-State
function instead of legacy ACPI P-States.

As this is a static check, it should be based upon what is currently
present on the system. This makes probeing more deterministic.
While local APIC flags field (lapic_flags) of cpu core in MADT table is
0, then the cpu core won't be enabled. In this case, _CPC won't be found
in this core, and return back to _CPC invalid with walking through
possible cpus (include disable cpus). This is not expected, so switch to
check present CPUs instead.

In case of an error in mlx5e_set_features(), 'netdev->features' must be
updated with the correct state of the device to indicate which features
were updated successfully.
To do that we maintain a copy of 'netdev->features' and update it after
successful feature changes, so we can assign it to back to
'netdev->features' if needed.
However, since not all netdev features are handled by the driver (e.g.
GRO/TSO/etc), some features may not be updated correctly in case of an
error updating another feature.
For example, while requesting to disable TSO (feature which is not
handled by the driver) and enable HW-GRO, if an error occurs during
HW-GRO enable, 'oper_features' will be assigned with 'netdev->features'
and HW-GRO turned off. TSO will remain enabled in such case, which is a
bug.
To solve that, instead of using 'netdev->features' as the baseline of
'oper_features' and changing it on set feature success, use 'features'
instead and update it in case of errors.

[WHY]
Current implementation of pipe split policy prevents pipe split with
multiple displays connected, which caused the MCLK speed to be stuck at
max
[HOW]
Changed the pipe split policies so that pipe split is allowed for
multi-display configurations

[Why]
A porting error on a previous patch left the block of code that
causes the crash from a NULL pointer dereference.
More specifically, we try to access link_enc before it's assigned in
the USB4 case in the following assignment:
config.dio_output_idx = link_enc->transmitter - TRANSMITTER_UNIPHY_A;
[How]
That assignment occurs later depending on the ASIC version. It's only
needed on DCN31 and only after link_enc is already assigned.

[Why]
We'll exit optimized power state to do link detection but we won't enter
back into the optimized power state.
This could potentially block s2idle entry depending on the sequencing,
but it also means we're losing some power during the transition period.
[How]
Hook up the handler like DCN21. It was also missed like the
exit_optimized_pwr_state callback.

[Why]
Otherwise SMU won't mark Display as idle when trying to perform s2idle.
[How]
Mark the bit in the dcn31 codepath, doesn't apply to older ASIC.
It needed to be split from phy refclk off to prevent entering s2idle
when PSR was engaged but driver was not ready.

[why]
B0 PHY C map to F, D map to G driver use logic instance, dmub does the

[how]
use phyical instance when program PHY register.

There are currently 2 ways to create a set of sysfs files for a
kobj_type, through the default_attrs field, and the default_groups
field. Move the cpufreq code to use default_groups field which has been
the preferred way since aa30f47cf666 ("kobject: Add support for default
attribute groups to kobj_type") so that we can soon get rid of the
obsolete default_attrs field.

It was reported that when PCIe PTM is enabled, some lockups could

While the issue is investigated, we can disable crosstimestamp for
those models and see no loss of functionality, because those models
don't have any support for time synchronization.

The D-Link DSB-650TX (2001:4002) is unable to receive Ethernet frames
that are longer than 1518 octets, for example, Ethernet frames that
contain 802.1Q VLAN tags.
The frames are sent to the pegasus driver via USB but the driver
discards them because they have the Long_pkt field set to 1 in the
received status report. The function read_bulk_callback of the pegasus
driver treats such received "packets" (in the terminology of the
hardware) as errors but the field simply does just indicate that the
Ethernet frame (MAC destination to FCS) is longer than 1518 octets.
It seems that in the 1990s there was a distinction between
"giant" (> 1518) and "runt" (< 64) frames and the hardware includes
flags to indicate this distinction. It seems that the purpose of the
distinction "giant" frames was to not allow infinitely long frames due
to transmission errors and to allow hardware to have an upper limit of
the frame size. However, the hardware already has such limit with its
2048 octet receive buffer and, therefore, Long_pkt is merely a
convention and should not be treated as a receive error.
Actually, the hardware is even able to receive Ethernet frames with 2048
octets which exceeds the claimed limit frame size limit of the driver of
1536 octets (PEGASUS_MTU).
