[Why]
Begin convergence with upstream Color Manager refactor
(fda768acb2a1 "drm/amd/display: Sync dcn42 with DC 3.2.373") by
consolidating fragmented per-plane CM state (shaper, 3DLUT, blend,
CM2) into a single dc_plane_cm structure shared by dc_plane_state
and dc_surface_update. Legacy fields are gated behind TRIM_CM2 so
that it keeps compatibility with other repositories.
[How]
Refactored to use newer structures.
No functional behavior change intended. Under !TRIM_CM2 the legacy
fields are still populated for compatibility with other repositories.
v2: squash in conflicting types fix

The project_id field stored in dml2_core_instance and related

represents unnecessary coupling between the core layer and
project-specific identifiers.

UTS_RELEASE evaluates to a static string and changes quite easily (e.g.
uncommitted changes in the source tree or new commits). So when checking
if a patch introduces changes to the resulting binary each usage of
UTS_RELEASE is source of annoyance.
Instead of using UTS_RELEASE directly use init_utsname()->release which
evaluates to the same string but with that a change of UTS_RELEASE
doesn't affect amdgpu_dev_coredump.o.

The cleaner shader sysfs path allocates a 16-dword (64 byte) IB but
incorrectly fills (align_mask + 1) dwords. On GFX rings align_mask is
0xff, so the loop wrote 256 dwords into a 64-byte buffer, causing a
kernel page fault.
The IB only needs to be a minimal NOP shell to schedule the job; the
cleaner shader itself is emitted on the ring via emit_cleaner_shader().
Fill 16 dwords to match the allocation.
v2: Use ib_size_dw variable (Lijo)

SMI events were reporting incorrect PIDs in containerized environments,
causing test failures where container processes expected to see their
namespace-local PIDs but instead received global host PIDs.
The issue had two root causes:
1. Event functions were called from kernel context (page fault handlers,
migration workers) where 'current' refers to the kernel worker thread,
not the userspace GPU process that triggered the event.
2. PID conversion used task_tgid_vnr() which returns the PID in the
caller's namespace (init namespace for kernel threads), not the task's
own namespace.
This patch updates the SMI event interface:
- Change 8 event function signatures to accept task_struct pointer
instead of pid_t, allowing proper namespace-aware PID conversion
- Convert PIDs using task_tgid_nr_ns(task, task_active_pid_ns(task))
which returns the PID as the process sees it via getpid()
- Update 10 call sites to pass p->lead_thread (the GPU process)
instead of p->lead_thread->pid or current (kernel worker)
This ensures SMI events report container-local PIDs, which is critical
for containerized GPU workloads to correctly correlate events with their
processes.

amdgpu_gfx_reset_mes_compute() runs amdgpu_mes_suspend(adev, 0) to
quiesce all gangs, resets the offending queue(s), then resumes. The
existing amdgpu_gfx_mes_reset_queue() called amdgpu_ring_reset_helper_end()
right after unmap/restore/map of the reset queue, which re-emits backed-up
commands and rings the doorbell. That doorbell hits a still-suspended CP:
on the subsequent resume the queue partially wedges -- the first new IB
after the reset may execute but later submissions stall, which surfaces
as repeated timeouts on the same ring under concurrent workloads.
Split out amdgpu_gfx_mes_reset_queue_start() (backup + MES reset +
unmap/restore/map only) and defer helper_end. amdgpu_gfx_reset_mes_compute()
collects the (ring, fence) pair for every queue it resets and runs
helper_end on each after amdgpu_mes_resume(), so the re-emit doorbells
land on a running CP. amdgpu_gfx_reset_mes_kcq() now reports the matched
ring/fence back to the caller for the same reason.

[Why&How]
Periodic detection callbacks from DCN35 was removed for higher IPS
residency causing some displays to fail to recover after DPMS sleep. The
monitors bounces HPD ~1.2s after link training, and without periodic
detection the system enters IPS with no mechanism to wake and rediscover
the display.
Restore the periodic detection calls in dcn35_clk_mgr for now. It should
be replaced with a proper IPS-aware solution long term using DMUB.
Also remove it from dcn31 and dcn314_clk_mgr.c since they do not have IPS,
thus should not affect them.

[WHAT]
Fix three issues amdgpu_dm_crc.c:
- Use cur_crc_src instead of source when deciding whether to call
drm_dp_stop_crc() in the disable path of set_crc_source(). When
disabling CRC, source is always NONE so dm_is_crc_source_dprx(source)
was always false, meaning drm_dp_stop_crc() was never called when
stopping a DPRX CRC source. Use cur_crc_src to check what was
previously active instead.
- Replace fragile 'source < 0' comparisons in verify_crc_source() and
set_crc_source() with AMDGPU_DM_PIPE_CRC_SOURCE_INVALID.
and avoiding signed/unsigned enum comparison concerns.
- Remove redundant NULL initializations for drm_dev and acrtc in
handle_crc_irq(). Both variables are unconditionally assigned right
after.

There is an issue that is seemingly limited to DCN42 where systems with
IOMMU enabled will hang during reboot stress testing. The hang happens shortly
after DCN PG exit happens and HUBP is programmed for the first flip, but before
the first surface address is latched. Testing has shown that disabling
DCCG_GLOBAL_FGCG_REP_DIS, HUBP_FGCG_REP_DIS, and DCFCLK_GATE_DIS can mask this
issue.
Disable FGCG for these three repeater bits to avoid issue while debug is on-going.

gfx_v10_0_hw_fini+0x41/0x150 [amdgpu]

amdgpu_device_ip_resume_phase2() skips IP blocks whose status.hw is
already set, but amdgpu_device_ip_suspend_phase2() never had the
matching guard, so a block can be suspended twice (e.g. a reset or
recovery issued while the device is already suspended). The second
suspend runs hw_fini again, which now releases the gfx fault IRQs
unconditionally, dropping a refcount that is already zero and tripping
the WARN_ON in amdgpu_irq_put().
The fault/EOP IRQ get/put were balanced through late_init/hw_fini
before, which masked the double-suspend; moving the get into hw_init
made the suspend/resume asymmetry visible as an IRQ refcount underflow.
Honor status.hw in ip_suspend_phase2() so suspend mirrors resume and a
block is only torn down once.
Fixes: 9117d8be850b ("drm/amdgpu/gfx: move fault and EOP IRQ get/put to hw_init/hw_fini")
Fixes: 482f0e538580 ("drm/amdgpu: fix double ucode load by PSP(v3)")

When kfd_queue_acquire_buffers() was split off from
set_queue_properties_from_user(), set_queue_properties_from_criu()
was missed. Thus, set_queue_properties_from_criu() is not
filling out the buffer fields of queue_properties, which
can come up when subsequent code expects them to be non-null.
Add the proper call to kfd_queue_acquire_buffers(), and also
use the right cast types in set_queue_properties_from_criu()
(which were missed at the same time)

During smu_v15_0_0_system_features_control(), the driver sends a
PrepareMp1ForUnload message to PMFW. PMFW then performs nBIF and SYSHUB
function-level resets (FLR), disabling PCIe CFG space reset, which
clears the framebuffer enable bit to zero and disables MC (memory controller)
access from the host.
Re-enable MC access via the nbio mc_access_enable callback right after
PrepareMp1ForUnload completes in smu_v15_0_0_system_features_control().

Set secure_submission_supported = true for the VCN unified ring funcs in
vcn_v4_0_5.c so secure IBs are allowed on the unifiedring.
Without this, protected decode submissions are blocked by the
common IB gate and can fail playback for secure content.
For vcn_v4_0_5.c (fixed STX VCN version), secure submission is
enabled directly in the ring funcs definition.
This change only advertises existing hardware/firmware capability;
non-secure decode paths are unaffected.
