[PATCH v7 00/26] drm/i915/display: All patches to make PREEMPT_RT work on i915 + xe.

[Maarten Lankhorst]

New version with patch from Sebastian to fix starvation of irq_work.

Still need feedback on the vblank approach, and check to see if there are some bugs left.

[PATCH v7 01/26] drm/vblank_work: Add methods to schedule vblank_work in 2 stages

[Maarten Lankhorst]

In case of vblank evasion in intel/display, it's necessary to
perform some work in advance, so the critical section will always run in
constant time on PREEMPT_RT.

By preparing all the work in advance, the part that needs to finish in
constant time only has to write a single variable instead. This allows
PREEMPT_RT to keep the interrupts disabled at the most critical part,
without completely reworking all locks to be raw spinlocks.

[PATCH v7 02/26] drm/vblank: Add a 2-stage version of drm_crtc_arm_vblank_event

[Maarten Lankhorst]

When trying to fix the hardware programming in intel/display, I had
to take all the vblank locks with local_irqs_disabled(). This
required converting the entire vblank code to raw spinlocks.

In the alternative approach, do all preparations in advance, and only
enable the vblank_event with interrupts disabled, this requires only
a simple write and prevents a complete re-architecture of the code.

[PATCH v7 04/26] drm/intel/display: Convert vblank event handling to 2-stage arming

[Maarten Lankhorst]

This is converts the vblank functions to be called with interrupts
disabled, even on PREEMPT_RT kernels.

Because the PREEMPT_RT kernel converts all spinlocks to rt-mutexes,
the normal vblank functions cannot be used inside the critical section.

Instead, prepare the vblank at the start, and then enable the vblank
work after the hardware programming is completed.

This allows us to keep programming the hardware with interrupts
disabled, and still schedule completion on PREEMPT_RT on next vblank.

[PATCH v7 05/26] drm/i915/display: Move vblank put until after critical section

[Maarten Lankhorst]

drm_crtc_vblank_put may take some locks, this should probably
not be the first thing we do after entering the time sensitive
part.

A better place is after programming is completed. Add a flag
to put the vblank after completion.

In the case of drm_vblank_work_schedule, we may not even need
to disable the vblank interrupt any more if it takes its own
reference.

[PATCH v7 06/26] drm/i915/display: Remove locking from intel_vblank_evade critical section

[Maarten Lankhorst]

finish_wait() may take a lock, which means that it can take any amount
of time. On PREEMPT-RT we should not be taking any lock after disabling
preemption, so ensure that the completion is done before disabling
interrupts.

This also has the benefit of making vblank evasion more deterministic,
by performing the final vblank check after all locking is done.

Now that we have a macro, might as well handle the VLV dsi workaround
too.

This makes the vblank evasion code slightly more deterministic, by not
looping with interrupts disabled.

[PATCH v7 08/26] drm/i915: Use preempt_disable/enable_rt() where recommended

[Maarten Lankhorst]

From: Mike Galbraith <umgwanakikbuti@gmail.com>

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 interrupts and so region remains preemptible.

The area covers only register reads and writes. The part that worries me
is:
- __intel_get_crtc_scanline() the worst case is 100us if no match is
  found.

- intel_crtc_scanlines_since_frame_timestamp() not sure how long this
  may take in the worst case.

It was in the RT queue for a while and nobody complained.
Disable preemption on PREEPMPT_RT during timestamping.

[PATCH v7 10/26] drm/i915/display: Do not take uncore lock in i915_get_vblank_counter

[Maarten Lankhorst]

This fixes a lockdep splat that occurs in the code that should be run
with interrupts disabled. The uncore lock should not be taken and
released repeatedly in a timing sensitive path.

Don't use the dmc lock inside the vblank critical section,
not even as last call.

[PATCH v7 13/26] drm/i915/display: Use intel_de_write_fw in intel_pipe_fastset

[Maarten Lankhorst]

intel_set_pipe_src_size(), hsw_set_linetime_wm(),
intel_cpu_transcoder_set_m1_n1() and intel_set_transcoder_timings_lrr()
are called from an atomic context on PREEMPT_RT, and should be using the
_fw functions.

This likely prevents a deadlock on i915.

Again noticed when trying to disable preemption in vblank evasion:

[PATCH v7 15/26] drm/i915/display: Fix intel_lpe_audio_irq_handler for PREEMPT-RT

[Maarten Lankhorst]

The LPE audio interrupt comes from the i915 interrupt handler. It
should be in irq disabled context.

With PREEMPT_RT enabled, the IRQ handler is threaded.
Because intel_lpe_audio_irq_handler() may be called in threaded IRQ context,
generic_handle_irq_safe API disables the interrupts before calling LPE's
interrupt top half handler.

This fixes braswell audio issues with RT enabled.

[PATCH v7 16/26] drm/i915/gt: Use spin_lock_irq() instead of local_irq_disable() + spin_lock()

[Maarten Lankhorst]

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

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() has each one caller
only. If intel_engine_cs::active::lock is acquired and released with the
_irq suffix then it behaves almost as if execlists_dequeue() would be
invoked with disabled interrupts. The difference is the last part of the
function which is then invoked with enabled interrupts.
I can't tell if this makes a difference. From looking at it, it might
work to move the last unlock at the end of the function as I didn't find
anything that would acquire the lock again.

[PATCH v7 17/26] drm/i915: Drop the irqs_disabled() check

[Maarten Lankhorst]

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

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
annotation below already check if the lock has been acquired by the
caller and will yell if the interrupts are not disabled.

Remove the !irqs_disabled() check.

[PATCH v7 18/26] drm/i915/guc: Consider also RCU depth in busy loop.

[Maarten Lankhorst]

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

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.

Also check if RCU is disabled for PREEMPT-RT, which is the case when
local_bh_disable() is called.

[PATCH v7 22/26] drm/i915: Use sleeping selftests for igt_atomic on PREEMPT_RT

[Maarten Lankhorst]

This makes the i915 selftests slightly happier, especially
related to GPU reset.

I believe this may be a better approach than trying to convert
uncore->lock to raw_spinlock

Re: [PATCH v7 24/26] PREEMPT_RT injection

[kernel test robot]

Hello,

we made a similar report two weeks ago. again, we cannot understand well the
purpose of this patch set, this report is just FYI what we observed in our
tests.

by this commit, a big config diff is introduced comparing to parent [1]

then a boot test which can pass on parent commit (previous patch) now fails
persistently.

[PATCH v7 25/26] FOR-CI: bump MAX_STACK_TRACE_ENTRIES

[Maarten Lankhorst]

We're hitting a bug in CI where MAX_STACK_TRACE_ENTRIES is set too low.
My guess is the repeated loading/unloading is creating multiples of the
same entries. As a hack just reset lockdep. This might only be necessary
for CI + PREEMPT_RT.

[PATCH v7 26/26] drm/i915/gt: Add a spinlock to prevent starvation of irq_work.

[Maarten Lankhorst]

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

IRQ-Work (FIFO-1) will be preempted by the threaded-interrupt (FIFO-50)
and the interrupt will poll on signaler_active while the irq-work can't
make progress.

Solve this by adding a spinlock to prevent starvation and force
completion.

The threaded-interrupt is the interrupt.

And this does not work because spin_is_locked() returns true and spins
forever. This fails because there is a "corner case" where
spin_is_locked() returns but the lock has no lock owner as in locked.
This happens if there is a waiter which did not yet acquire the lock. 

So if you happy with this, we could keep it ;)

It seems CI is a lot happier too now.

Xe:
https://patchwork.freedesktop.org/series/159034/#rev14

BAT passes, the full run has some minor issues but only kms_vblank systematic.
Likely due to the fundamental changes of the PREEMPT_RT kernel itself, nothing driver specific.

i915:
https://patchwork.freedesktop.org/series/159035/#rev14

A few new warnings, and some noise. The most worrying part is the i915 execlists selftest
failing on nearly all platforms:

<3>[  504.279024] i915/intel_execlists_live_selftests: live_preempt_user failed with error -62
...
<7>[  506.799685] [IGT] i915_selftest: finished subtest execlists, FAIL

I don't know what's going on there yet, likely needs more debugging. Could be the test itself
being written incorrectly or something else entirely.

Otherwise things are looking good! Have you uncovered anything else?

Kind regards,

I would swap the ordering 23 <-> 26 in

| ├─>[PATCH v7 26/26] drm/i915/gt: Add a spinlock to prevent starvation of irq_work.

but other than that it all looks good. I tested it by using it on my two
boxes with i915 compatible hw and didn't notice anything.
I've been using -next + this series.

Forgot to mention: This is fine on PREEMPT_RT but on !RT you might need

               spin_lock_irqsave(&b->signaler_active_sync, flags);
               spin_unlock_irqrestore(&b->signaler_active_sync, flags);

if the function can be called from !IRQ context which might be the case
due to the irqsave() earlier in this function.

Yeah seems a bit of an oversight. I'll change it to use flags.

Is it correct to assume that irq_work disables interrupts on !RT?

Yes. It runs either directly as an interrupt or gets kicked from the
timer interrupt. Either way, interrupts are always disabled. Only on RT
interrupts are enabled unless the IRQ-work has been explicitly requested
to be run in interrupt context.
