drm/i915: Use intel_crtc_needs_modeset() more

2022-11-03T16:25:47+00:00

Prefer our own intel_crtc_needs_modeset() wrapper to drm_atomic_crtc_needs_modeset() whenever we are dealing with the intel_ types instead of drm_ types. Makes things a bit neater in general.

GEN7_DOP_CLOCK_GATE_ENABLE bit should be cleared, not inverse. The bug was introduced during conversion to intel_uncore_rmw helper.

drm/i915/gt: Always use MCR functions on multicast registers

2022-10-17T17:15:47+00:00

Rather than relying on the implicit behavior of intel_uncore_*() functions, let's always use the intel_gt_mcr_*() functions to operate on multicast/replicated registers. v2: - Add TLB invalidation registers v3: - Switch more uncore operations in mmio_invalidate_full() to MCR operations for Xe_HP.

drm/i915/gen8: Create separate reg definitions for new MCR registers

2022-10-17T17:12:43+00:00

Gen8 was the first time our hardware had multicast registers (or at least the first time the multicast nature was exposed and MMIO accesses could be steered). There are some registers that transitioned from singleton behavior to multicast during the gen7 -> gen8 transition; let's duplicate the register definitions for those registers in preparation for upcoming patches that will handle MCR registers in a special manner. The registers adjusted are: * MISCCPCTL * SAMPLER_INSTDONE * ROW_INSTDONE * ROW_CHICKEN2 * HALF_SLICE_CHICKEN1 * HALF_SLICE_CHICKEN3 v2: - Use the gen8 version of HALF_SLICE_CHICKEN3 in GVT's gen9 engine MMIO list. (Bala) - Update to the gen8 version of MISCCPCTL in a couple new workarounds that were recently added for DG2/PVC.

Let's not forget to mark the unused watermark levels as invalid after the readout. The vlv/chv codepath has this but the g4x didn't for some reason.
