drm/amd/display: add max bandwidth budget to QoS interface

[Why]
The QoS reporting interface lacked a field to expose the maximum
active memory bandwidth budget. Adding this field allows callers to
observe the effective bandwidth ceiling.

[How]
Rename struct memory_qos to dc_measured_memory_qos and introduce
a new struct dc_requested_memory_qos holding bandwidth lower bound,
calculated average bandwidth, latency upper bounds, and max bandwidth
budget. Add a get_requested_memory_qos function pointer to
clk_mgr_funcs. Update dc_get_qos_info to call through the new
function pointer and populate all requested QoS fields including
qos_max_bw_budget_in_mbps in dc_qos_info.

drm/amd/display: fix buffer overruns warnings

[Why & How]
Fixes a warning by adding bounds checks and index validation in dml2_0
sources to address static analysis warnings. Ensures safe array access and
prevents out-of-bounds reads by validating indices before use, improving

assignments.

drm/amd/display: Fix type mismatches using guards and explicit casts

[Why]
Address signed/unsigned comparison warnings across dc paths to keep
builds warning-clean and improve type safety at comparison boundaries.
Most warnings came from signed loop/index temporaries compared against
unsigned counters and table sizes, plus a smaller number of mixed
signed/unsigned clock, bandwidth, and geometry comparisons.

[How]
Aligned iterator and temporary variable types with the semantic type
of the compared bounds. Used unsigned indices for loops bounded by unsigned
counters and table sizes, while retaining signed types where values are
semantically signed or participate in arithmetic that may legitimately go
negative. Where mixed signed/unsigned comparisons are intentional, applied
explicit boundary casts or guarded comparisons instead of broad type
changes.

No functional behavior changes are intended; this is a warning-resolution
and type-alignment cleanup.

[Why]
Address signed/unsigned comparison warnings across dc paths to keep

Most warnings came from signed loop/index temporaries compared against

[How]
Aligned loop/index and bound types in the affected modules and DMUB
sources, including color, freesync, power, stats, and vmid paths.
Used unsigned iterators where bounds/counters are unsigned, preserved
signed types where negative values are meaningful, and updated related
format specifiers where type changes required it. Changes are limited to

to keep builds warning-clean and improve type safety at comparison
boundaries. Most warnings came from signed loop/index temporaries compared
against unsigned counters (for example pipe_count, num_states, and

[How]
Aligned iterator and temporary variable types with the semantic type

counters, and retained signed types where values are semantically signed

are intentional, applied explicit boundary casts instead of broad type
changes (for example dispclk minimum clamp and selected timing/height
comparisons).

As a side effect of converting count parameters such as
NumberOfActivePlanes to unsigned, normalized equivalent loop forms from:

for (i = 0; i <= NumberOfActivePlanes - 1; i++)

into the normalized form:

for (i = 0; i < NumberOfActivePlanes; i++)

to keep bound style coherent and avoid avoidable mismatch patterns.

No functional behavior changes are intended; this is a warning-resolution
and type-alignment cleanup.

drm/amdgpu: zero-initialize GART table on allocation

GART TLB is flushed after unmapping but not after mapping. Since
amdgpu_bo_create_kernel() does not zero-initialize the buffer, when a
single PTE is written the TLB may speculatively load other uninitialized
entries from the same cacheline. Those garbage entries can appear valid,
and a subsequent write to another PTE in the same cacheline may cause the
GPU to use a stale garbage PTE from the TLB.

Fix this by calling memset_io() to zero-initialize the GART table with
gart_pte_flags immediately after allocation.

Using AMDGPU_GEM_CREATE_VRAM_CLEARED, SDMA-based clear will not work

drm/amd/display: dmub_cmd.h: add missing kernel-doc for enums

For enums that have a kernel-doc ("/**") comment block, add or correct
their kernel-doc to eliminate all kernel-doc enum warnings.

Some of these needed "struct" changed to "enum" in the kernel-doc header.
For a few of them, I changed the "/**" comment to a plain "/*"
comment since there was no kernel-doc content there.

Example:

Warning: drivers/gpu/drm/amd/display/dmub/inc/dmub_cmd.h:2673 Enum value 'FAMS2_ALLOW_DELAY_CHECK_NONE' not described in enum 'dmub_fams2_allow_delay_check_mode'

Warning: drivers/gpu/drm/amd/display/dmub/inc/dmub_cmd.h:2673 Enum value 'FAMS2_ALLOW_DELAY_CHECK_FROM_PREPARE' not described in enum 'dmub_fams2_allow_delay_check_mode'

[Why]

Rapid vblank off is causing flip-done timeouts for NV3x and newer

A proper fix requires further investigation. In lieu of it, let's

drm/amd/display: fix root clock disabled when DSC power gate disabled for DCN314

[Why]
When set debug.disable_dsc_power_gate = true, the original code
uses an early return to skip the power gate sequence and root
clock enable and disable.

For this case, install new driver without uninstall old driver.
The sequence like below:
1. On the power-off path, the old driver will power gate dsc and
   disable_dsc() (root clock disable) due to
   debug.disable_dsc_power_gate = false.
2. On the power-on path, the new driver will force power on dsc but skip
   enable_dsc() (root clock enable) due to
   debug.disable_dsc_power_gate = true.

Finally, when mode needs DSC but the root clock is disabled, underflow
happened.

[How]
- Moving enable_dsc() before the disable_dsc_power_gate check so the
  root clock is always enabled on the power-on path.
- Replacing the early return with a goto that skips only the power gate
  register writes, allowing disable_dsc() to still execute on the
  power-off path.

drm/amd/display: Unify fast update classification paths

[Why]
The dc_fast_update intermediate struct created code duplication and
complexity with multiple classification paths (populate_fast_updates,
fast_nonaddr_updates_exist, full_update_required). This refactoring
simplifies the update classification system by consolidating to a
single path while maintaining compatibility and adding comprehensive
test coverage for fast sequence functionality.

[How]
Remove entire dc_fast_update struct and associated helper functions:
- populate_fast_updates
- fast_nonaddr_updates_exist
- full_update_required
and
- Refactor check_update_surfaces_for_stream as the
  single classification path with explicit handling for func_shaper,
  lut3d_func, cursor_csc_color_matrix_change and
  scaler_sharpener_update.
- Add reserved bitfields to surface_update_flags and
  stream_update_flags unions for completeness guards.
- Extract dc_check_address_only_update and
  dc_check_update_surfaces_for_stream as public.
- Add comprehensive test coverage with parameterized tests for all
  FAST flags, update classification tests for MED/FULL paths,
  and completeness guard tests.

drm/amd/display: Fix narrowing boundaries in dml

[Why]
DML code paths include implicit integer narrowing at protocol and
storage boundaries. Making these boundaries explicit improves clarity
and reduces warning noise while preserving behavior.

[How]
Apply explicit C-style casts at intentional narrowing boundaries
across DML calculation, mode support, RQ/DLG, wrapper, and DSC
helper paths.
Keep intermediate arithmetic in natural-width types where practical,
with minor type-consistency cleanups where needed. Add explicit
boundary casts for intentional narrowing and keep intermediate math
in wider types where practical, with small type-consistency cleanups
to maintain behavior and readability.

drm/amdkfd: Validate CRIU-restored IDs before idr_alloc

The KFD CRIU restore flow restores previously saved object IDs from
userspace.

For event restore:

  kfd_criu_restore_event()
      -> create_signal_event() / create_other_event()
          -> allocate_event_notification_slot()
              -> idr_alloc(..., *restore_id, *restore_id + 1, ...)

For BO restore:

  criu_restore_memory_of_gpu()
      -> idr_alloc(..., bo_priv->idr_handle, ...)

In both cases, the restored ID comes from userspace-provided CRIU data.

idr_alloc() expects the ID range values to fit within signed int
limits. If a restored ID is larger than INT_MAX, it can trigger a WARN
in the IDR layer.

A kernel WARN is undesirable because it prints a warning trace and may
cause a panic or reboot on systems with panic_on_warn enabled.

Smatch reported these paths as allowing unchecked userspace values to
reach idr_alloc().

Add INT_MAX validation before using restored IDs in:

- kfd_criu_restore_event()
- criu_restore_memory_of_gpu()

If the restored ID is invalid, return -EINVAL.

This prevents invalid restore data from reaching the IDR layer and
avoids WARN-triggering paths, while keeping valid restore behavior
unchanged.
