7edb503fe4 drm/amd/pm: Disable MMIO access during SMU Mode 1 reset
During Mode 1 reset, the ASIC undergoes a reset cycle and becomes
temporarily inaccessible via PCIe. Any attempt to access MMIO registers
during this window (e.g., from interrupt handlers or other driver threads)
can result in uncompleted PCIe transactions, leading to NMI panics or
system hangs.

To prevent this, set the `no_hw_access` flag to true immediately after
triggering the reset. This signals other driver components to skip
register accesses while the device is offline.

A memory barrier `smp_mb()` is added to ensure the flag update is
globally visible to all cores before the driver enters the sleep/wait
state.

bd8150a1b3 drm/amdgpu: Refactor amdgpu_gem_va_ioctl for Handling Last Fence Update and Timeline Management v4
This commit simplifies the amdgpu_gem_va_ioctl function, key updates
include:
 - Moved the logic for managing the last update fence directly into
   amdgpu_gem_va_update_vm.
 - Introduced checks for the timeline point to enable conditional
   replacement or addition of fences.

v2: Addressed review comments from Christian.
v3: Updated comments (Christian).
v4: The previous version selected the fence too early and did not manage its
    reference correctly, which could lead to stale or freed fences being used.
    This resulted in refcount underflows and could crash when updating GPU
    timelines.
    The fence is now chosen only after the VA mapping work is completed, and its
    reference is taken safely. After exporting it to the VM timeline syncobj, the
    driver always drops its local fence reference, ensuring balanced refcounting
    and avoiding use-after-free on dma_fence.

GFX ring resets work differently on pre-GFX10 hardware since

For ring reset, you need issue the reset via CP_VMID_RESET
via KIQ or MMIO and submit the following to the gfx ring to
complete the reset:
1. EOP packet with EXEC bit set
2. WAIT_REG_MEM to wait for the fence
3. Clear CP_VMID_RESET to 0
4. EVENT_WRITE ENABLE_LEGACY_PIPELINE
5. EOP packet with EXEC bit set
6. WAIT_REG_MEM to wait for the fence
Once those commands have completed the reset should
be complete and the ring can accept new packets.

ISP mfd child devices are using genpd and the system suspend-resume
operations between genpd and amdgpu parent device which uses only
runtime suspend-resume are not in sync.

Linux power manager during suspend-resume resuming the genpd devices
earlier than the amdgpu parent device. This is resulting in the below
warning as SMU is in suspended state when genpd attempts to resume ISP.

To fix this warning isp suspend-resume is handled as part of amdgpu
parent device suspend-resume instead of genpd sequence. Each ISP MFD
child device is marked as dev_pm_syscore_device to skip genpd
suspend-resume and use pm_runtime_force api's to suspend-resume
the devices when callbacks from amdgpu are received.

73d08a87d6 drm/amd/display: Remove unnecessary divider update flag
[Why]
When transitioning from 640x480 at RBRx1 to HBR3x1,
both output pixel mode and pixel rate divider should update.
The needs_divider_update flag was only for 8b10b and 128b132b transition.

[How]
Remove needs_divider_update flag.

5ad5b0b784 drm/amd/display: Fix and reenable UPDATE_V3_FLOW_NEW_CONTEXT_MINIMAL
[Why]
Reenable new split implementation, previously partially reverted due
to issues with ODM on high-bandwidth displays 4k144Hz, resulting
in a corrupted gray screen.

Minimal flows require two separate commits, with extra intermediate
commit to enable seamless transitions, each followed by a swap. Since
new design requires commit to be run in execute and swap in cleanup
stage, an attempt was made to reorder them from CSCS (Commit-Swap-Commit-Swap)
to CCSS (Commit-Commit-Swap-Swap). Not only is this not viable, but
was implemented incorrectly as CCS, one swap missing.

[How]
* Change UPDATE_V3_FLOW_NEW_CONTEXT_MINIMAL_NEW/CURRENT to execute
and cleanup one commit, then run UPDATE_V3_FLOW_NEW_CONTEXT_SEAMLESS,
which closely matches old implementation where minimal flows fall back
to seamless.
* Fix uninitialized variable error.

fd3fece04d drm/amd/display: Fix P010, NV12, YUY2 scale down by four times failure
[WHY]
When performing 4:1 downscaling with subsampled formats,
the SPL remainder distribution logic (+1) overrides the
upper layer’s aligned width, resulting in odd segment
widths and causing hang.

The upper layer alignment ensures the width is sufficient
and even, so SPL should not modify it further.

[HOW]
In dc_spl.c within calculate_mpc_slice_in_timing_active,
add an extra condition: Skip the remainder distribution
(+1) when use_recout_width_aligned is true.This change
respects the upper layer’s alignment decision, prevents
odd widths, and is a minimal, safe fix.

af3303970d drm/amd/display: Fix mismatched unlock for DMUB HW lock in HWSS fast path
[Why]
The evaluation for whether we need to use the DMUB HW lock isn't the
same as whether we need to unlock which results in a hang when the
fast path is used for ASIC without FAMS support.

[How]
Store a flag that indicates whether we should use the lock and use
that same flag to specify whether unlocking is needed.
