a57942bfdd ALSA: hda: Make audio component support more generic
This is the final step for more generic support of DRM audio
component.  The generic audio component code is now moved to its own
file, and the symbols are renamed from snd_hac_i915_* to
snd_hdac_acomp_*, respectively.  The generic code is enabled via the
new kconfig, CONFIG_SND_HDA_COMPONENT, while CONFIG_SND_HDA_I915 is
kept as the super-class.

Along with the split, three new callbacks are added to audio_ops:
pin2port is for providing the conversion between the pin number and
the widget id, and master_bind/master_unbin are called at binding /
unbinding the master component, respectively.  All these are optional,
but used in i915 implementation and also other later implementations.

A note about the new snd_hdac_acomp_init() function: there is a slight
difference between this and the old snd_hdac_i915_init().  The latter
(still) synchronizes with the master component binding, i.e. it
assures that the relevant DRM component gets bound when it returns, or
gives a negative error.  Meanwhile the new function doesn't
synchronize but just leaves as is.  It's the responsibility by the
caller's side to synchronize, or the caller may accept the
asynchronous binding on the fly.

v1->v2: Fix missing NULL check in master_bind/unbind

ae891abe7c drm/i915: Split audio component to a generic type
For allowing other drivers to use the DRM audio component, rename the
i915_audio_component_* with drm_audio_component_*, and split the
generic part into drm_audio_component.h.  The i915 specific stuff
remains in struct i915_audio_component, which contains
drm_audio_component as the base.

The license of drm_audio_component.h is kept to MIT as same as the the
original i915_component.h.

This is a preliminary change for further development, and no
functional changes by this patch itself, merely code-split and
renames.

v1->v2: Use SPDX for drm_audio_component.h, fix remaining i915
        argument in drm_audio_component.h

a8bd3b884d drm/i915: Flush chipset caches after GGTT writes
Our I915g (early gen3, the oldest machine we have in the farm) is still
reporting occasional incoherency performing the following operations:

  1) write through GGTT (indirect write into memory)
  2) write through either CPU or WC (direct write into memory)
  3) read from GGTT (indirect read)

Instead of reporting the value from (2), the read from GGTT reports the
earlier value written via the GGTT. We have made sure that the writes are
flushed from the CPU (commit 3a32497f0d ("drm/i915/selftests: Provide
full mb() around clflush") and commit add00e6d89 ("drm/i915: Flush the
WCB following a WC write")), but still see the error, just less
frequently. The only remaining cache that might be affected here is a
chipset cache, so flush that as well.

d8b3f454da drm/sun4i: sun8i: Avoid clearing blending order at each atomic commit
Blending order is set based on the z position of each DRM plane. The
blending order register is currently cleared at each atomic DRM commit,
with the intent that each committed plane will set the appropriate
bits (based on its z-pos) when enabling the plane.

However, it sometimes happens that a particular plane is left unchanged
by an atomic commit and thus will not be configured again. In that
scenario, blending order is cleared and only the bits relevant for the
planes affected by the commit are set. This leaves the planes that did
not change without their blending order set in the register, leading
to that plane not being displayed.

Instead of clearing the blending order register at every atomic commit,
this change moves the register's initial clear at bind time and only
clears the bits for a specific plane when disabling it or changing its
zpos.

This way, planes that are left untouched by a DRM atomic commit are
no longer disabled.

d778847208 drm/i915/selftests: Free the backing store between iterations
In the huge pages tests, we may have lots of objects being trapped on
the freelist as we hold the struct_mutex allowing the free worker no
opportunity to recover the backing store. We also have stricter
requirements and the desire for large contiguous pages, further
increasing the allocation pressure. To reduce the chance of running out
of memory, we could either drop the mutex and flush the free worker, or
we could release the backing store directly. We do the latter in this
patch for simplicity.

b5aa3f4aef drm/amdkfd: Call kfd2kgd.set_compute_idle
User mode queue submissions don't go through KFD. Therefore we don't
know exactly when compute is idle or not idle. We use the existence
of user mode queues on a device as an approximation.

register_process is called when the first queue of a process is
created. Conversely unregister_process is called when the last queue
is destroyed. The first process that is registered takes compute
out of idle. The last process that is unregisters sets compute back
to idle.

On reset/wedging, we cancel all pending replies from the HW and we also
want to cancel an outstanding preemption event. Since we use the same
function to cancel the pending replies for reset and for a preemption
event, we can simply clear the active tracking for all.

v2: Keep execlists_user_end() markup for wedging
v3: Move assignment to inline to hide the bare assignment.

a18b219294 drm/dp_helper: Add DP aux channel tracing
This is something we've needed for a very long time now, as it makes
debugging issues with faulty MST hubs along with debugging issues
regarding us interfacing with hubs correctly vastly easier to debug.
Currently this can actually be done if you trace the i2c devices for DP
using ftrace but that's significantly less useful for a couple of
reasons:

- Tracing the i2c devices through ftrace means all of the traces are
  going to contain a lot of "garbage" output that we're sending over the
  i2c line. Most of this garbage comes from retrying transactions, DRM's
  helper library adding extra transactions to work around bad hubs, etc.
- Having a user set up ftrace so that they can provide debugging
  information is a lot more difficult then being able to say "just boot
  with drm.debug=0x100"
- We can potentially expand upon this tracing in the future to print
  debugging information in regards to other DP transactions like MST
  sideband transactions

This is inspired by a patch Rob Clark sent to do this a long time back.
Neither of us could find the patch however, so we both assumed it would
probably just be easier to rewrite it anyway.

71a5cb3eb7 drm: writeback: Fix doc that says connector should be disconnected
During iteration process one of the proposed mechanism for not
breaking existing userspace was to report writeback connectors as
disconnected, however the final version used
DRM_CLIENT_CAP_WRITEBACK_CONNECTORS for that purpose.

b58262396f drm/imx: imx-ldb: disable LDB on driver bind
The LVDS signal integrity is only guaranteed when the correct enable
sequence (first IPU DI, then LDB) is used. If the LDB display output was
active before the imx-drm driver is loaded (like when a bootsplash was
active) the DI will be disabled by the full IPU reset we do when loading
the driver. The LDB control registers are not part of the IPU range and
thus will remain unchanged.

This leads to the LDB still being active when the DI is getting enabled,
effectively reversing the required enable sequence. Fix this by also
disabling the LDB on driver bind.

d530b5f1ca drm: re-enable error handling
drm_legacy_ctxbitmap_next() returns idr_alloc() which can return
-ENOMEM, -EINVAL or -ENOSPC none of which are -1 . but the call sites
of drm_legacy_ctxbitmap_next() seem to be assuming that the error case
would be -1 (original return of drm_ctxbitmap_next() prior to 2.6.23
was actually -1). Thus reenable error handling by checking for < 0.

f1a498fa54 drm/i915/execlists: Disable submission tasklet upon wedging
If we declare the driver wedged before the GPU truly is, then we may see
the GPU complete some CS events following our cancellation. This leaves
us quite confused as we deleted all the bookkeeping and thus complain
about the inconsistent state.

We can just ignore the remaining events and let the GPU idle by not
feeding it, and so avoid trying to racily overwrite shared state. We
rely on there being a full GPU reset before unwedging, giving us the
opportunity to reset the shared state.

the attempted aborted unload, we may still get a call to i915_pci_remove()

Give in, since CI continues to incorrectly insist that KERN_NOTICE is a

intention was to use the message to indicate which tests might warrant
an extended run, but virtually all tests require a timeout so it is
simply not as interesting as first thought.
