2026-01-06drm/amd/display: Pass proper DAC encoder ID to VBIOSTimur Kristóf4-5/+12
Similarly to the analog_engine field, add a new analog_id field which contains the encoder ID of the analog encoder that corresponds to the link encoder. Previously, the default encoder ID of the link encoder was used, which meant that we passed the wrong ID in case of DVI-I.

2026-01-06drm/amdgpu/gfx9: Implement KGQ ring resetAlex Deucher1-3/+89
GFX ring resets work differently on pre-GFX10 hardware since there is no MQD managed by the scheduler. 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.

2026-01-06drm/amdgpu/gfx9: rework pipeline sync packet sequenceAlex Deucher1-30/+37
Replace WAIT_REG_MEM with EVENT_WRITE flushes for all shader types and ACQUIRE_MEM. That should accomplish the same thing and avoid having to wait on a fence preventing any issues with pipeline syncs during queue resets.

2026-01-06drm/amd/amdgpu: Fix SMU warning during isp suspend-resumePratap Nirujogi3-0/+67
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. WARNING: CPU: 13 PID: 5435 at drivers/gpu/drm/amd/amdgpu/../pm/swsmu/amdgpu_smu.c:398 smu_dpm_set_power_gate+0x36f/0x380 [amdgpu] 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.

2026-01-06drm/amd/display: Fix and reenable UPDATE_V3_FLOW_NEW_CONTEXT_MINIMALDominik Kaszewski1-41/+39
[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.

2026-01-06drm/amd/display: Fix P010, NV12, YUY2 scale down by four times failureKaier Hsueg1-1/+2
[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.
