[PATCH 0/7] drm/i915: All fixes to make i915 work well with PREEMPT_RT.

[Maarten Lankhorst <dev@lankhorst.se>]

All fixes to make the core i915 module (without display) working correctly on
PREEMPT_RT.

Some fixes are still needed, as the selftests still fail. But otherwise the
test results were looking good on PREEMPT_RT.

Maarten Lankhorst (3):
  drm/i915/gt: Fix selftests on PREEMPT_RT
  drm/i915/gt: Set stop_timeout() correctly on PREEMPT-RT
  drm/i915: Use sleeping selftests for igt_atomic on PREEMPT_RT

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.
  drm/i915/gt: Add a spinlock to prevent starvation of irq_work.
