drm/amd/display: Don't try AUX transactions on disconnected link
[Why]
Setting link DPMS off in response to HPD disconnect creates AUX
transactions on a link that is supposed to be disconnected. This can

source to re-enable the link.
[How]
Avoid AUX transactions on disconnected link.

drm/amdkfd: add a new flag to manage where VRAM allocations go
On big and small APUs we send KFD VRAM allocations to GTT
since the carve out is either non-existent or relatively
small. However, if someone sets the carve out size to be
relatively large, we may end up using GTT rather than VRAM.
No change of logic with this patch, but it allows the
driver to determine which logic to use based on the
carve out size in the future.

drm/amdgpu/gfx10: Enable cleaner shader for GFX10.1.1/10.1.2 GPUs
Enable the cleaner shader for GFX10.1.1/10.1.2 GPUs to provide data
isolation between GPU workloads. The cleaner shader is responsible for
clearing the Local Data Store (LDS), Vector General Purpose Registers
(VGPRs), and Scalar General Purpose Registers (SGPRs), which helps
prevent data leakage and ensures accurate computation results.
This update extends cleaner shader support to GFX10.1.1/10.1.2 GPUs,
previously available for GFX10.1.10. It enhances security by clearing
GPU memory between processes and maintains a consistent GPU state across
KGD and KFD workloads.

drm/amd/display: Account For OTO Prefetch Bandwidth When Calculating Urgent Bandwidth
[Why]
1) The current calculations for OTO prefetch bandwidth do not consider the number of DPP pipes in use.
As a result, OTO prefetch bandwidth may be larger than the vactive bandwidth if multiple DPP pipes are used.
OTO prefetch bandwidth should never exceed the vactive bandwidth.
2) Mode programming may be mismatched with mode support
In cases where mode support has chosen to use the equalized (equ) prefetch schedule,
mode programming may end up using oto prefetch schedule instead.
The bandwidth required to do the oto schedule may end up being higher than the equ schedule.
This can cause the required urgent bandwidth to exceed the available urgent bandwidth.
[How]
Output the oto prefetch bandwidth and incorperate it into the urgent bandwidth calculations
even if the prefetch schedule being used is not the oto schedule.

drm/amdgpu/gfx10: Add cleaner shader for GFX10.1.10
This commit adds the cleaner shader microcode for GFX10.1.0 GPUs. The
cleaner shader is a piece of GPU code that is used to clear or
initialize certain GPU resources, such as Local Data Share (LDS), Vector
General Purpose Registers (VGPRs), and Scalar General Purpose Registers
(SGPRs).
Clearing these resources is important for ensuring data isolation
between different workloads running on the GPU. Without the cleaner
shader, residual data from a previous workload could potentially be
accessed by a subsequent workload, leading to data leaks and incorrect
computation results.
The cleaner shader microcode is represented as an array of 32-bit words
(`gfx_10_1_0_cleaner_shader_hex`). This array is the binary
representation of the cleaner shader code, which is written in a
low-level GPU instruction set.
When the cleaner shader feature is enabled, the AMDGPU driver loads this
array into a specific location in the GPU memory. The GPU then reads
this memory location to fetch and execute the cleaner shader
instructions.
The cleaner shader is executed automatically by the GPU at the end of
each workload, before the next workload starts. This ensures that all
GPU resources are in a clean state before the start of each workload.
This addition is part of the cleaner shader feature implementation. The
cleaner shader feature helps resource utilization by cleaning up GPU
resources after they are used. It also enhances security and reliability
by preventing data leaks between workloads.

When not set `gttsize` module parameter by default will get the
value to use for the GTT pool from the TTM page limit, which is
set by a separate module parameter.
This inevitably leads to people not sure which one to set when they
want more addressable memory for the GPU, and you'll end up seeing
instructions online saying to set both.
Add some messages to try to guide people both who are using or misusing
the parameters and mark the parameter as deprecated with the plan to
drop it after the next LTS kernel release.
