7e0b367db8 drm/amd/display: Init clock value by current vbios CLKs
[Why]
While booting into OS, driver updates DPP/DISP CLKs.
But init clock value is zero which is invalid.

[How]
Get current clocks value to update init clocks.
To avoid underflow.

5eb3c85e34 Merge branch 'etnaviv/next' of https://git.pengutronix.de/git/lst/linux into drm-next
Again, nothing big this time. Mostly a new performance counter from
Christian, some more lockdep annotations from Guido and removal of
functionality that duplicates driver core from Robin.

ccc9e67ab2 drm/i915/display: Defer initial modeset until after GGTT is initialised
Prior to sanitizing the GGTT, the only operations allowed in
intel_display_init_nogem() are those to reserve the preallocated (and
active) regions in the GGTT leftover from the BIOS. Trying to allocate a
GGTT vma (such as intel_pin_and_fence_fb_obj during the initial modeset)
may then conflict with other preallocated regions that have not yet been
protected.

Move the initial modesetting from the end of init_nogem to the beginning
of init so that any vma pinning (either framebuffers or DSB, for example),
is after the GGTT is ready to handle it.

This will prevent the DSB object from being destroyed too early:

aff76ab795 drm/i915/gt: Limit frequency drop to RPe on parking
We treat idling the GT (intel_rps_park) as a downclock event, and reduce
the frequency we intend to restart the GT with. Since the two workloads
are likely related (e.g. a compositor rendering every 16ms), we want to
carry the frequency and load information from across the idling.
However, we do also need to update the frequencies so that workloads
that run for less than 1ms are autotuned by RPS (otherwise we leave
compositors running at max clocks, draining excess power). Conversely,
if we try to run too slowly, the next workload has to run longer. Since
there is a hysteresis in the power graph, below a certain frequency
running a short workload for longer consumes more energy than running it
slightly higher for less time. The exact balance point is unknown
beforehand, but measurements with 30fps media playback indicate that RPe
is a better choice.

78b2eb8a1f drm/i915/gt: Retain default context state across shrinking
As we use a shmemfs file to hold the context state, when not in use it
may be swapped out, such as across suspend. Since we wrote into the
shmemfs without marking the pages as dirty, the contents may be dropped
instead of being written back to swap. On re-using the shmemfs file,
such as creating a new context after resume, the contents of that file
were likely garbage and so the new context could then hang the GPU.

Simply mark the page as being written when copying into the shmemfs
file, and it the new contents will be retained across swapout.

2bfdf30246 drm/i915/gt: Split the breadcrumb spinlock between global and contexts
As we funnel more and more contexts into the breadcrumbs on an engine,
the hold time of b->irq_lock grows. As we may then contend with the
b->irq_lock during request submission, this increases the burden upon
the engine->active.lock and so directly impacts both our execution
latency and client latency. If we split the b->irq_lock by introducing a
per-context spinlock to manage the signalers within a context, we then
only need the b->irq_lock for enabling/disabling the interrupt and can
avoid taking the lock for walking the list of contexts within the signal
worker. Even with the current setup, this greatly reduces the number of
times we have to take and fight for b->irq_lock.

Furthermore, this closes the race between enabling the signaling context
while it is in the process of being signaled and removed:

This is caused by virtual engines where although we take the breadcrumb
lock on each of the active engines, they may be different engines on
different requests, It turns out that the b->irq_lock was not a
sufficient proxy for the engine->active.lock in the case of more than
one request, so introduce an explicit lock around ce->signals.

v2: ce->signal_lock is acquired with only RCU protection and so must be
treated carefully and not cleared during reallocation. We also then need
to confirm that the ce we lock is the same as we found in the breadcrumb
list.

9261a1db80 drm/i915/gt: Protect context lifetime with RCU
Allow a brief period for continued access to a dead intel_context by
deferring the release of the struct until after an RCU grace period.
As we are using a dedicated slab cache for the contexts, we can defer
the release of the slab pages via RCU, with the caveat that individual
structs may be reused from the freelist within an RCU grace period. To
handle that, we have to avoid clearing members of the zombie struct.

This is required for a later patch to handle locking around virtual
requests in the signaler, as those requests may want to move between
engines and be destroyed while we are holding b->irq_lock on a physical
engine.

v2: Drop mutex_reinit(), if we never mark the mutex as destroyed we
don't need to reset the debug code, at the loss of having the mutex
debug code spot us attempting to destroy a locked mutex.
v3: As the intended use will remain strongly referenced counted, with
very little inflight access across reuse, drop the ctor.
v4: Drop the unrequired change to remove the temporary reference around
dropping the active context, and add back some more missing ctor
operations.
v5: The ctor is back. Tvrtko spotted that ce->signal_lock [introduced
later] maybe accessed under RCU and so needs special care not to be
reinitialised.
v6: Don't mix SLAB_TYPESAFE_BY_RCU and RCU list iteration.

03a6636730 drm/amd/display: use FB pitch to fill dc_cursor_attributes
Instead of relying on pitch (in pixels) == width, use the FB pitch. This
is less confusing to readers, and works correctly if we ever support FBs
with a pitch (in pixels) != width.

This also makes the code symmetrical with fill_plane_buffer_attributes.
