Hi,
The following patches are from the PREEMPT_RT queue. It is mostly about
disabling interrupts/preemption which leads to problems. Unfortunately
DRM_I915_LOW_LEVEL_TRACEPOINTS had to be disabled because it acquires locks
from within trace points. Making the lock a raw_spinlock_t led to higher

Mario Kleiner suggest in commit
ad3543ede630f ("drm/intel: Push get_scanout_position() timestamping into kms
driver.")
a spots where preemption should be disabled on PREEMPT_RT. The
difference is that on PREEMPT_RT the intel_uncore::lock disables neither
preemption nor in
intel_guc_send_busy_loop() looks at in_atomic() and irqs_disabled() to
decide if it should busy-spin while waiting or if it may sleep.
Both checks will report false on PREEMPT_RT if sleeping spinlocks are
acquired leading to RCU splats while the function sleeps.
Check also if RCU has been disabled
The !irqs_disabled() check triggers on PREEMPT_RT even with
i915_sched_engine::lock acquired. The reason is the lock is transformed
into a sleeping lock on PREEMPT_RT and does not disable interrupts.
There is no need to check for disabled interrupts. The lockdep

Commit
8d7849db3eab7 ("drm/i915: Make sprite updates atomic")
started disabling interrupts across atomic updates. This breaks on PREEMPT_RT
because within this section the code attempt to acquire spinlock_t locks which
are sleeping locks on PREEMPT_RT.
According to the c
execlists_dequeue() is invoked from a function which uses
local_irq_disable() to disable interrupts so the spin_lock() behaves
like spin_lock_irq().
This breaks PREEMPT_RT because local_irq_disable() + spin_lock() is not
the same as spin_lock_irq().
execlists_dequeue_irq() and execlists_dequeue()
The !in_atomic() check in _wait_for_atomic() triggers on PREEMPT_RT
because the uncore::lock is a spinlock_t and does not disable
preemption or interrupts.
Changing the uncore:lock to a raw_spinlock_t doubles the worst case
latency on an otherwise idle testbox during testing.
Ignore _WAIT_FOR_ATO

Hi Dave & Sima -
Another feature pull towards v6.11, hopefully last. This should also fix
the 32-bit build issue [1] seen in drm-next.

There is difference with tile4 on Xe2 platforms vs older platforms where
for tile4 is always enabled decompression on display when on Xe2. This
will cause requirement to be aligned for ccs with framebuffer strides
with tile4. Maybe need to consider new modifier for Xe2 because of this
requirement.
On Xe2 platform with tile4 decompression is enabled unconditionally
hence consider tile4 as ccs modifier
