2025-11-19drm/{i915,xe}/display: move irq calls to parent interfaceJani Nikula-79/+111
Add an irq parent driver interface for the .enabled and .synchronize calls.

2025-11-19drm/{i915, xe}/display: duplicate gen2 irq/error init/reset in display irqJani Nikula-76/+73
Duplicate gen2_irq_reset(), gen2_assert_iir_is_zero(), gen2_irq_init(), gen2_error_reset(), and gen2_error_init() in intel_display_irq.c. This allows us to drop the duplicates from xe, and prepares for future cleanups. Although duplication is undesirable in general, in this case the local duplicates lead to a cleaner end result. There's a slight wrinkle in gen2_assert_iir_is_zero().

2025-11-19drm/i915/dram: Fix ICL DIMM_S decodingVille Syrjälä-64/+155
Unfortunately the MAD_DIMM DIMM_S and DIMM_L bits on ICL are not idential, so we are currently decoding DIMM_S incorrectly. Fix the problem by defining the DIMM_S and DIMM_L bits separately.

2025-11-19drm/xe/vm: Use for_each_tlb_inval() to calculate invalidation fencesMatt Roper-8/+7
ops_execute() calculates the size of a fence array based on XE_MAX_GT_PER_TILE, while the code that actually fills in the fence array uses a for_each_tlb_inval() iterator. This works out okay today since both approaches come up with the same number of invalidation fences (2: primary GT invalidation + media GT invalidation), but could be problematic in the future if there isn't a 1:1 relationship between TLBs needing invalidation and potential GTs on the tile. Adjust the allocation code to use the same for_each_tlb_inval() counting logic as the code that fills the array to future-proof the code.

2025-11-19drm/i915/cx0: Update C10/C20 state calculationMika Kahola-35/+40
Update several functions in intel_cx0_phy.c to make PLL state management more explicit. Changes include * add 'const' qualifiers to intel_crtc_state parameter for cx0 state calculation functions * refactor C10/C20 PLL state calculations helpers to take explicit hardware state pointers instead of directly modifying 'crtc_state->dpll_hw_state' Signed-off-by: Imre Deak <imre.deak@intel.com> Signed-off-by: Mika Kahola <mika.kahola@intel.com> Reviewed-by: Suraj Kandpal <suraj.kandpal@intel.com> Link: https://lore.kernel.org/r/20251117104602.2363671-18-mika.kahola@intel.com
