When we run out of VMIDs we need to wait for some to become available.
Previously we were using a dma_fence_array for that, but this means that
we have to allocate memory.
Instead just wait for the first not signaled fence from the least recently
used VMID to signal. That is not as efficient since we end up in this
function multiple times again, but allocating memory can easily fail or
deadlock if we have to wait for memory to become available.
v2: remove now unused VM manager fields
v3: fix dma_fence reference

The amd-smi tool relies on extended peer link information to report xgmi
link metrics. The necessary xgmi ta command, GET_EXTEND_PEER_LINKS, has
been enabled in the host driver and this change is necessary for the
guest to make use of it. To handle the case where the host driver does
not have the latest xgmi ta, the guest driver checks for guest support
through a pf2vf feature flag before invoking psp.

amdgpu_xgmi_fill_topology_info and psp_xgmi_reflect_topology_info
perform the same logic of copying topology info of one node to every
other node in the hive. Instead of having two functions that purport to
do the same thing, this refactoring moves the logic of the fill function
to the reflect function and adds reflecting port number info as well for
complete functionality.

The amdgpu driver has been working well on CIK dGPUs for years.
Now that the DC analog connector support landed, these GPUs
are at feature parity with the old radeon driver.
Additionally, amdgpu yields extra performance, supports Vulkan

robust power management.

QCS615 platform requires non-default logical-to-physical lane mapping due
to its unique hardware routing. Unlike the standard mapping sequence
<0 1 2 3>, QCS615 uses <3 2 0 1>, which necessitates explicit
configuration via the data-lanes property in the device tree. This ensures
correct signal routing between the DP controller and PHY.
For partial definitions, fill remaining lanes with unused physical lanes
in ascending order.

To support high-resolution cases that exceed the width limitation of
a pair of SSPPs, or scenarios that surpass the maximum MDP clock rate,
additional pipes are necessary to enable parallel data processing
within the SSPP width constraints and MDP clock rate.
Request 4 mixers and 4 DSCs for high-resolution cases where both DSC
and dual interfaces are enabled. More use cases can be incorporated
later if quad-pipe capabilities are required.

This commit introduces core infrastructure for handling GSP command and
message queues in the nova-core driver. The command queue system enables
bidirectional communication between the host driver and GSP firmware
through a remote message passing interface.
The interface is based on passing serialised data structures over a ring
buffer with separate transmit and receive queues. Commands are sent by
writing to the CPU transmit queue and waiting for completion via the
receive queue.
To ensure safety mutable or immutable (depending on whether it is a send
or receive operation) references are taken on the command queue when
allocating the message to write/read to. This ensures message memory
remains valid and the command queue can't be mutated whilst an operation
is in progress.
Currently this is only used by the probe() routine and therefore can
only used by a single thread of execution. Locking to enable safe access
from multiple threads will be introduced in a future series when that
becomes necessary.

smaller type
There are times where we need to store a constant value defined as a
larger type (e.g. through a binding) into a smaller type, knowing
that the value will fit. Rust, unfortunately, only provides us with the
`as` operator for that purpose, the use of which is discouraged as it
silently strips data.
Extend the `num` module with functions allowing to perform the
conversion infallibly, at compile time.
Example:
const FOO_VALUE: u32 = 1;
// `FOO_VALUE` fits into a `u8`, so the conversion is valid.
let foo = num::u32_to_u8::<{ FOO_VALUE }>();
We are going to use this feature extensively in Nova.

Currently, SSPPs are assigned to a maximum of two pipes. However,
quad-pipe usage scenarios require four pipes and involve configuring
two stages. In quad-pipe case, the first two pipes share a set of
mixer configurations and enable multi-rect mode when certain

converting pipe into pipe array later.

There are 2 interfaces and 4 pingpong in quad pipe. Map the 2nd
interface to 3rd PP instead of the 2nd PP.

Current code only supports usage cases with one pair of mixers at
most. To support quad-pipe usage case, two pairs of mixers need to
be reserved. The lm_count for all pairs is cleared if a peer
allocation fails in current implementation. Reset the current lm_count
to an even number instead of completely clearing it. This prevents all
pairs from being cleared in cases where multiple LM pairs are needed.

Compute more of the required FB layout information to boot the GSP
firmware.
This information is dependent on the firmware itself, so first we need
to import and abstract the required firmware bindings in the `nvfw`
module.
Then, a new FB HAL method is introduced in `fb::hal` that uses these
bindings and hardware information to compute the correct layout
information.
This information is then used in `fb` and the result made visible in
`FbLayout`.
These 3 things are grouped into the same patch to avoid lots of unused
warnings that would be tedious to work around. As they happen in
different files, they should not be too difficult to track separately.

Calls to xe_force_wake_put() should generally pass the exact reference
returned by xe_force_wake_get(). Since OA grabs and releases forcewake
in different functions, xe_oa_stream_destroy() is currently calling put
with a hardcoded ALL mask. Although this works for now, it's somewhat
fragile in case OA moves to more precise power domain management in the
future.
Stash the original reference obtained during stream initialization
inside the stream structure so that we can use it directly when the
stream is destroyed.
