2025-09-05drm/i915/dram: Move 16Gb DIMM detection fully to the skl/icl codepathsVille Syrjälä
We are incorrectly applying the 16Gb DIMM w/a (adding 1 extra usec to WM0 latency) on MTL+ even though the w/a is only needed for SKL/ICL. The current way of setting this is up is a bit of a disaster: 1. always set has_16gb_dimms=true for all platforms except BXT/GLK 2. has_16gb_dimms potentially gets overwritten with something else * BXT/GLK don't do anything since we never set has_16gb_dimms to begin with * skl_get_dram_info() overwrites has_16gb_dimms with the actual detection results for SKL/ICL/derivatives * gen12_get_dram_info() (correctly) resets has_16gb_dimms for TGL/ADL/derivatives * xelpdp_get_dram_info() doesn't do anything, leaving has_16gb_dimms incorrectly set for MTL+ Clean up the whole mess by only setting has_16gb_dimms in the SKL/ICL codepaths where we have the actual detection code for it. This avois applying the w/a incorrectly on MTL+. v2: Rewrite commit msg (Jani) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250902133113.18778-6-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula <jani.nikula@intel.com>

2025-09-05drm/i915/display: Remove power state verification before HW readoutImre Deak
During system resume the display power state verification will print the "power well x state mismatch (refcount 0/enabled 1)" error message from the early resume sequence for a power well left enabled by BIOS. This power well was probably left enabled by BIOS inadvertently, since BIOS versions on current platforms do not leave any display output enabled while resuming from an Sx power state, hence the enabled display power well is unused. In theory however it is possible that BIOS leaves a display output enabled, in that case the enabled power well shouldn't be reported as an error. According to the above, remove the display power state verification from the early resume phase to avoid incorrectly reporting an enabled power well without a power reference as an error. Note: The refcount for any enabled and used power well (i.e. used for an enabled display output) will be acquired following the early resume sequence, after the HW state for display outputs (encoder/crtc etc.) is read out. Any power well enabled but not used (hence not holding a reference) will be disabled after the HW state readout. The display power state will be verified afterwards in intel_power_domains_enable().

2025-09-04thermal: gov_step_wise: Allow cooling level to be reduced earlierRafael J. Wysocki
The current behavior of the Step-wise thermal governor is to increase the cooling level one step at a time after trip point threshold passing by thermal zone temperature until the temperature stops to rise. Then, nothing is done until the temperature decreases below the (possibly updated) trip point threshold, at which point the cooling level is reduced straight to the applicable minimum. While this generally works, it is not in agreement with the throttling logic description comment in step_wise_manage() any more after some relatively recent changes, and in the case of passive cooling, it may lead to undesirable performance oscillations between high and low levels. For this reason, modify the governor's cooling device state selection function, get_target_state(), to reduce cooling by one level even if the temperature is still above the thermal zone threshold, but the temperature has started to fall down. However, ensure that the cooling level will remain above the applicable minimum in that case to pull the zone temperature further down, possibly until it falls below the trip threshold (which may now be equal to the low temperature of the trip). Doing so should help higher performance to be restored earlier in some cases which is desirable especially for passive trip points with relatively high hysteresis values. Signed-off-by: Rafael J.
