Original amdgpu_cper_fini skips all CPER cleanup work for any SR-IOV VF directly.
When AMDGIM_FEATURE_RAS_CPER is enabled on VF side, CPER related buffers/workitems
are allocated during initialization, but the old code returns early without
releasing these resources, which leads to kernel memory leak.

User-space read/write syscalls interpret positive driver return values
as successful transfer sizes. Our current RAS wrappers return positive

Allow early FB reads to fall back to BAR0 when the VRAM aperture is not ready.
This lets SR-IOV VFs consume host-provided init data before requesting full GPU access.
For ASICs that support request_init_data,
defer full GPU access until after non-GPU early init to shorten the full-access window.
Legacy ASICs(before NV12) do not send request_init_data;
the host dumps init data only during full GPU access,
so keep the original early full-access request path for them.

[why]
DSC over HDMI FRL (e.g. 4k144) was pruned by DML mode support
because the compressed FRL cap check was never reached.
dml32_TruncToValidBPP() validates the FRL output by calling
dml1_frl_cap_chk_inter() directly. The compressed-vs-uncompressed
dispatch (if params->compressed -> dml1_frl_cap_chk_compressed()) had
been moved up into the top-level dml1_frl_cap_chk() wrapper, leaving
dml1_frl_cap_chk_inter() as uncompressed-only. As a result a DSC stream
routed through TruncToValidBPP was validated against the full
uncompressed bandwidth, failed the cap check, and the mode was pruned
(vlevel == num_states).
[how]
Move the compressed dispatch back into dml1_frl_cap_chk_inter() so every
caller of _inter() (including TruncToValidBPP) honours params->compressed.
This matches the internal DAL tree.

[Why]
mode_support reads mode_lib.ms.uclk_pstate_switch_modes to enforce the
vactive pstate margin, but nothing populates it: the memset clears it and
the PMO selection is never passed in. The check always sees na and never
runs, so a plane with negative vactive margin can still pass and blank the
display.
[How]
Add a const per-plane pstate-method pointer to mode_support_ex, point it at
stage3.pstate_switch_modes when stage 3 has run (NULL otherwise), and copy
it into mode_lib.ms after the memset. Scope the support-required check to
the vactive methods it governs (vactive, fw_vactive_drr) so SVP, DRR and
vblank planes are not rejected by the vactive support flag.

[Why]
mode_support does not require UCLK pstate today, so later PMO optimization
stages can push a plane's VActive latency-hiding margin below zero without
rechecking that the config still supports UCLK pstate. This can blank the
display on high-bandwidth configs.
[How]
Plumb the PMO-selected per-plane pstate method into mode_support and fail
the config only when UCLK pstate is required (method != na) but not
supported. For planes committed to a vactive method, require a non-negative
VActive latency-hiding margin, and skip the check when all streams are
blanked. No-op the PMO DCN42 pstate test (returning false only on the
initial candidate so the optimize/FAMS2 stage-3 setup still runs), since
reserved time is guaranteed by the override and the vactive margin is now
enforced in core mode_support.

The dcc_rate value does not affect any watermark, TTU or DLG output; it
only affects the Z8 stutter-related logging. The hardware
DisplayModeSupported formula uses a dcc_rate of 4, while DML2 currently
uses 1.

If a plane reaches calculate_mcache_setting with a zero-area viewport,
calculate_mcache_setting exits early with num_mcaches == 0 and
mvmpg_width/height == 0. This will cause a divide-by-zero panic and can
also cause an underflow on num_mcaches.
Fix this by changing calculate_mcache_setting to bool and adding guards
after each calculate_mcache_row_bytes call. If num_mcaches or
mvmpg_width/height is zero, return a false. Callers will propagate the
failure as a rejected mode, which prevents the panic.

[why]
The Apple Studio Display primary tile advertises both the full 5120x2880
mode and the per-tile 2560x2880 timing. With the secondary tile already
hidden from userspace, the stray 2560x2880 mode on the primary connector
can still be picked by compositors, defeating the single 5K stream goal.
[how]
Prune the per-tile timing from the primary connector during get_modes:
when the sink carries the disable_second_tile quirk and the connector is
the primary tile (tile_h_loc == 0 && tile_v_loc == 0), drop any probed
mode matching the advertised tile size (tile_h_size x tile_v_size) so
userspace only sees the full 5120x2880 mode.

Expand KUnit coverage for event_property_update() beyond the null
connector skip. Add cases for the disconnected, missing-state and
missing-device skip branches, plus the fully connected path where
hdcp_get_content_protection_from_status() maps HDCP_OFF to DESIRED and
HDCP1 TYPE0 encryption to ENABLED.
The connected-path tests use dm_kunit_alloc_adev() so the drm_device has
an initialised mode_config connection_mutex, and pre-set the connector
state to the expected content protection value so
drm_hdcp_update_content_protection() takes its no-change early return.

[WHAT]
dm_allocate_gpu_mem() and dm_free_gpu_mem() are generic DM service
helpers that wrap amdgpu_bo_create_kernel()/amdgpu_bo_free_kernel()
and track allocations on adev->dm.da_list. Move them out of
amdgpu_dm.c into amdgpu_dm_services.c alongside the other dm_* service
callbacks.
Both are already public and declared in amdgpu_dm.h; their callers in
amdgpu_dm_dmub.c and amdgpu_dm_helpers.c are unaffected. No functional
change.

[WHAT]
amdgpu_dm_smu_write_watermarks_table() pushes fixed dcn watermark
clock settings to the SMU on Navi1x. It belongs with the other
dc-pplib bridge code, so move it out of amdgpu_dm.c into
amdgpu_dm_pp_smu.c.
It is called from dm_resume(), so it becomes a plain exported function
declared in amdgpu_dm_pp_smu.h (now included by amdgpu_dm.c) instead of
STATIC_IFN_KUNIT in amdgpu_dm.h. Relocate its KUnit test from the
amdgpu_dm suite to the amdgpu_dm_pp_smu suite. No functional change.

[WHAT]
dm_should_disable_stutter() and its amdgpu_stutter_quirk PCI match
table are self-contained quirk logic. Move them out of amdgpu_dm.c
into amdgpu_dm_quirks.c alongside the existing DMI quirk handling.
The helper is called from amdgpu_dm_init(), so it becomes a plain
exported function instead of STATIC_IFN_KUNIT, and its declaration
moves from the KUnit-only block to a regular prototype in amdgpu_dm.h.
Relocate its KUnit tests from the amdgpu_dm suite to the
amdgpu_dm_quirks suite. No functional change.

[WHAT]
amdgpu_dm_update_stream_scaling_settings() computes the stream src/dst
rectangles for a connector's scaling mode. It is already declared in
amdgpu_dm_connector.h and consumed by create_stream_for_sink(), so move
its definition out of the oversized amdgpu_dm.c into
amdgpu_dm_connector.c where it belongs.
Relocate its KUnit tests from the amdgpu_dm suite to the
amdgpu_dm_connector suite accordingly. No functional change.

Port the three-frame wait logic from dcn30_set_avmute to
dce110_set_avmute so that older DCN versions (1.0, 2.0) also
wait for GCP packets to be sent out before proceeding.
This ensures HDMI sinks properly process the mute state,
preventing garbled display after link re-establishment.

both a populated work-queue and the zero-link / NULL-SRM path.

process_output() without arming the callback or watchdog timers.

Cover the per-connector scan in event_property_validate(): NULL,
disconnected and NULL-state connectors are skipped; a changed
encryption status updates the cached value and schedules
property_update_work; and an unchanged status leaves it
untouched.

Cover the HDCP display lifecycle helpers:
- hdcp_update_display() registers the connector and, on the
disable path, resets the per-link encryption status to
HDCP_OFF.
- hdcp_remove_display() reverts an ENABLED connector back to
DESIRED and clears the per-link entry, including the NULL
connector-state path.
- hdcp_reset_display() clears the encryption status and the
connector for every link.

Cover link_lock() across all links (lock then unlock) and the
max_link == 0 no-op path, checking each per-link mutex ends in
the expected state.
Also cover the psp_get_srm() and psp_set_srm() guard paths when
the HDCP TA context is uninitialized: psp_get_srm() returns NULL
and psp_set_srm() returns -EINVAL, both leaving their output
parameters untouched. The post-guard paths invoke real PSP
firmware and are not unit-testable in UML.
