2026-01-20drm/amd/display: Only poll analog connectorsTimur Kristóf
Analog connectors may be hot-plugged unlike other connector types that don't support HPD. Stop DRM from polling other connector types that don't support HPD, such as eDP, LVDS, etc. These were wrongly polled when analog connector support was added, causing issues with the seamless boot process.

[why & how] VBIOS DMCUB FW can enable FEC for capable eDPs, but S/W DC state is only updated for link0 when transitioning into OS with driver loaded. This causes issues when the eDP is immediately hidden and DIG0 is assigned to another link that does not support FEC. Driver will attempt to disable FEC but FEC enablement occurs based on the link state, which does not have fec_state updated since it is a different link. Thus, FEC disablement on DIG0 will get skipped and cause no light up.

2026-01-20drm/amd/amdgpu: Add independent hang detect work for user queue fenceJesse.Zhang
In error scenarios (e.g., malformed commands), user queue fences may never be signaled, causing processes to wait indefinitely. To address this while preserving the requirement of infinite fence waits, implement an independent timeout detection mechanism: 1. Initialize a hang detect work when creating a user queue (one-time setup) 2. Start the work with queue-type-specific timeout (gfx/compute/sdma) when the last fence is created via amdgpu_userq_signal_ioctl (per-fence timing) 3. Trigger queue reset logic if the timer expires before the fence is signaled v2: make timeout per queue type (adev->gfx_timeout vs adev->compute_timeout vs adev->sdma_timeout) to be consistent with kernel queues. (Alex) v3: The timeout detection must be independent from the fence, e.g. you don't wait for a timeout on the fence but rather have the timeout start as soon as the fence is initialized. (Christian) v4: replace the timer with the `hang_detect_work` delayed work.

2026-01-14drm/amdgpu/userq: Fix fence reference leak on queue teardown v2Srinivasan Shanmugam
The user mode queue keeps a pointer to the most recent fence in userq->last_fence. This pointer holds an extra dma_fence reference. When the queue is destroyed, we free the fence driver and its xarray, but we forgot to drop the last_fence reference. Because of the missing dma_fence_put(), the last fence object can stay alive when the driver unloads. This leaves an allocated object in the amdgpu_userq_fence slab cache and triggers This is visible during driver unload as: BUG amdgpu_userq_fence: Objects remaining on __kmem_cache_shutdown() kmem_cache_destroy amdgpu_userq_fence: Slab cache still has objects Call Trace: kmem_cache_destroy amdgpu_userq_fence_slab_fini amdgpu_exit __do_sys_delete_module Fix this by putting userq->last_fence and clearing the pointer during amdgpu_userq_fence_driver_free().

2026-01-14Revert "drm/amdgpu: don't attach the tlb fence for SI"Prike Liang
This reverts commit 820b3d376e8a102c6aeab737ec6edebbbb710e04. It’s better to validate VM TLB flushes in the flush‑TLB backend rather than in the generic VM layer. Reverting this patch depends on commit fa7c231fc2b0 ("drm/amdgpu: validate the flush_gpu_tlb_pasid()") being present in the tree.

2026-01-14drm/amd/display: Initialise backlight level values from hwVivek Das Mohapatra
Internal backlight levels are initialised from ACPI but the values are sometimes out of sync with the levels in effect until there has been a read from hardware (eg triggered by reading from sysfs). This means that the first drm_commit can cause the levels to be set to a different value than the actual starting one, which results in a sudden change in brightness. This path shows the problem (when the values are out of sync): amdgpu_dm_atomic_commit_tail() -> amdgpu_dm_commit_streams() -> amdgpu_dm_backlight_set_level(..., dm->brightness[n]) This patch calls the backlight ops get_brightness explicitly at the end of backlight registration to make sure dm->brightness[n] is in sync with the actual hardware levels.

2026-01-14drm/amd/display: Bump the HDMI clock to 340MHzMario Limonciello
[Why] DP-HDMI dongles can execeed bandwidth requirements on high resolution monitors. This can lead to pruning the high resolution modes.

2026-01-14drm/amd: Clean up kfd node on surprise disconnectMario Limonciello (AMD)
When an eGPU is unplugged the KFD topology should also be destroyed for that GPU. This never happens because the fini_sw callbacks never get to run. Run them manually before calling amdgpu_device_ip_fini_early() when a device has already been disconnected. This location is intentionally chosen to make sure that the kfd locking refcount doesn't get incremented unintentionally.
