2025-11-19drm/xe/vm: Use for_each_tlb_inval() to calculate invalidation fencesMatt Roper
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.

ACPI 6.6 specification for EINJV2 appends an extra structure to the end of the existing struct set_error_type_with_address.

2025-11-19regulator: make the subsystem aware of shared GPIOsBartosz Golaszewski
GPIOLIB is now aware of shared GPIOs and - for platforms where access to such pins is managed internally - we don't need to keep track of the enable count. Once all users in the kernel switch to using the new mechanism, we'll be able to drop the internal counting of users from the regulator code.

2025-11-19drm/i915/cx0: Enable dpll framework for MTL+Mika Kahola
MTL+ platforms are supported by dpll framework remove a separate check for hw comparison and rely solely on dpll framework hw comparison. Finally, all required hooks are now in place so initialize PLL manager for MTL+ platforms and remove the redirections to the legacy code paths from the following interfaces: * intel_encoder::clock_enable/disable() * intel_encoder::get_config() * intel_dpll_funcs::get_hw_state() * intel_ddi_update_active_dpll() * pipe_config_pll_mismatch() v2: Rebase on !HAS_LT_PHY check in intel_ddi_update_active_dpll() v3: Rebase on !display->dpll.mgr check in intel_ddi_update_active_dpll() Add check for NVL as the platform is not part of pll framework (Suraj) Signed-off-by: Mika Kahola <mika.kahola@intel.com> Reviewed-by: Suraj Kandpal <suraj.kandpal@intel.com> Link: https://lore.kernel.org/r/20251118132859.2584452-1-mika.kahola@intel.com
2025-11-19drm/i915/cx0: Add MTL+ Thunderbolt PLL hooksImre Deak
Add the PLL hooks for the TBT PLL on MTL+. These are simple stubs similarly to the TBT PLL on earlier platforms, since this PLL is always on from the display POV - so no PLL enable/disable programming is required as opposed to the non-TBT PLLs - and the clocks for different link rates are enabled/disabled at a different level, via the intel_encoder::enable_clock()/disable_clock() interface.
