Using the DMC wakelock is the official recommendation for Xe3_LPD. This
series apply fixes to the current DMC wakelock implementation and
enables it by default for Xe3_LPD. The series has been tested with a PTL
machine.
Gustavo Sousa (18):
drm/i915/dmc_wl: Use i915_mmio_reg_offset() instead of reg.reg
drm/xe: Mimic i915 behavior for non-sleeping MMIO wait
drm/i915/dmc_wl: Use non-sleeping variant of MMIO wait
drm/i915/dmc_wl: Check for non-zero refcount in release work
drm/i915/dmc_wl: Get wakelock when disabling dynamic DC states
drm/i915/dmc_wl: Use sentinel item for range tables
drm/i915/dmc_wl: Extract intel_dmc_wl_reg_in_range()
drm/i915/dmc_wl: Rename lnl_wl_range to powered_off_ranges
drm/i915/dmc_wl: Track registers touched by the DMC
drm/i915/dmc_wl: Allow simpler syntax for single reg in range tables
drm/i915/dmc_wl: Deal with existing references when disabling
drm/i915/dmc_wl: Couple enable/disable with dynamic DC states
drm/i915/dmc_wl: Add and use HAS_DMC_WAKELOCK()
drm/i915/dmc_wl: Init only after we have runtime device info
drm/i915/dmc_wl: Use HAS_DMC() in HAS_DMC_WAKELOCK()
drm/i915/dmc_wl: Sanitize enable_dmc_wl according to hardware support
drm/i915/dmc_wl: Do nothing until initialized
