drm/i915: Eliminate IS_MTL_DISPLAY_STEP Stepping-specific display behavior shouldn't be tied to MTL as a platform, but rather specifically to the Xe_LPD+ IP. Future non-MTL platforms may re-use this IP and will need to follow the exact same logic and apply the same workarounds. IS_MTL_DISPLAY_STEP() is dropped in favor of a new macro IS_DISPLAY_IP_STEP() that only checks the display IP version. v2: - Rename macro to IS_DISPLAY_IP_STEP for consistency with the corresponding GT macro and handle steppings the same way. v3: - Drop the automatic "STEP_" pasting. v4: - Implement IS_DISPLAY_IP_STEP on top of IS_DISPLAY_IP_RANGE / IS_DISPLAY_STEP building blocks and make the parameters from/until instead of begin/fixed. (Jani) - Fix usage details in comment. v5: - Tweak macro comment.

drm/i915/mtl: Add support for PM DEMAND MTL introduces a new way to instruct the PUnit with power and bandwidth requirements of DE. Add the functionality to program the registers and handle waits using interrupts. The current wait time for timeouts is programmed for 10 msecs to factor in the worst case scenarios. Changes made to use REG_BIT for a register that we touched(GEN8_DE_MISC_IER _MMIO). Wa_14016740474 is added which applies to Xe_LPD+ display v2: checkpatch warning fixes, simplify program pmdemand part v3: update to dbufs and pipes values to pmdemand register(stan) Removed the macro usage in update_pmdemand_values() v4: move the pmdemand_pre_plane_update before cdclk update pmdemand_needs_update included cdclk params comparisons pmdemand_state NULL check (Gustavo) pmdemand.o in sorted order in the makefile (Jani) update pmdemand misc irq handler loop (Gustavo) active phys bitmask and programming correction (Gustavo) v5: simplify pmdemand_state structure simplify methods to find active phys and max port clock Timeout in case of previou pmdemand task pending (Gustavo) v6: rebasing updates to max_ddiclk calculations (Gustavo) updates to active_phys count method (Gustavo) v7: use two separate loop to iterate throug old and new crtc states to calculate the active phys (Gustavo) v8: use uniform function names (Gustavo) v9: For phys change iterate through connectors (Imre) Look for change in phys for pmdemand update (Gustavo, Imre) Some more stlying changes (Imre) Update pmdemand state during HW readout/sanitize (Imre) v10: Fix CI checkpatch warnings v11: use correct pmdemand object pointer during hw readout, simplify the check for phys need update (Gustavo) v12: Handle possible non serialize cases (Imre) Initialise also pmdemand params HW readout (Imre) Update active phys mask during sanitize calls (Imre) Check TC/encoder changes to limit connector update (Imre) v13: Check display version before accessing pmdemand functions v14: Move is_serialized to intel_global_state.c simplify update params and other stlying issues (Imre) Bspec: 66451, 64636, 64602, 64603 Cc: Matt Atwood <matthew.s.atwood@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Cc: Gustavo Sousa <gustavo.sousa@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: Gustavo Sousa <gustavo.sousa@intel.com> Signed-off-by: Mika Kahola <mika.kahola@intel.com> Signed-off-by: Vinod Govindapillai <vinod.govindapillai@intel.com> Reviewed-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> #v4 Acked-by: Gustavo Sousa <gustavo.sousa@intel.com> #v11 Reviewed-by: Imre Deak <imre.deak@intel.com> [RK: Fixed minor typo in one of the comments. s/qclck_gc/qclk_gv/] Signed-off-by: Radhakrishna Sripada <radhakrishna.sripada@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230606201032.347449-1-vinod.govindapillai@intel.com
