[i915-rt v5 00/21] drm/i915/display: All patches to make PREEMPT_RT work on i915 + xe.

[Maarten Lankhorst <dev@lankhorst.se>]

We should probably take the uncore lock only once, and hold it during
entire evasion. For now just remove the code using it to see if CI
passes.

Since last time, adjust some patches to compile again, and also
add a lockdep_reset() to make CI pass from repeatedly loading
the i915 module.

Maarten Lankhorst (16):
  drm/i915/display: Fix intel_lpe_audio_irq_handler for PREEMPT-RT
  drm/i915/display: Make get_vblank_counter use intel_de_read_fw()
  drm/i915/display: Use intel_de_write_fw in intel_pipe_fastset
  drm/i915/display: Make set_pipeconf use the fw variants
  drm/i915/display: Move vblank put until after critical section
  drm/i915/display: Remove locking from intel_vblank_evade critical
    section
  drm/i915/display: Handle vlv dsi workaround in scanline_in_safe_range
    too
  drm/i915/display: Make icl_dsi_frame_update use _fw too
  drm/i915/display: Enable interrupts earlier on PREEMPT_RT
  drm/i915/display: Use intel_de_read/write_fw in colorops
  drm/i915/gt: Fix selftests on PREEMPT_RT
  drm/i915/gt: Set stop_timeout() correctly on PREEMPT-RT
  drm/i915/display: Do not take uncore lock in i915_get_vblank_counter
  drm/i915/display: Remove uncore lock from vlv_atomic_update_fifo
  PREEMPT_RT injection
  FOR-CI: drm/i915: Reset lockdep after selftest unload

Mike Galbraith (1):
  drm/i915: Use preempt_disable/enable_rt() where recommended

Sebastian Andrzej Siewior (4):
  drm/i915/gt: Use spin_lock_irq() instead of local_irq_disable() +
    spin_lock()
  drm/i915: Drop the irqs_disabled() check
  drm/i915/guc: Consider also RCU depth in busy loop.
