A long time ago, the slab header was added to multiple files in DC. We
also included it in the os_types.h, which is included in many of those
DC files. At this point, there is no need to insert the slab.h header in
multiple files, so this commit drops those includes.

[why]
The feature was disabled due to regression found during testing. Now
that all the pending issues are addressed, we are reenabling the power
saving feature again.
The feature optimizes dispclk level when user is using MPO capable
broswers or watching MPO capable videos in windowed mode. The feature
achieves power optimization by utilizing free pipes to process incoming
pixels in parallel. So it reduces max dispclk requirements for each
pipe.
Previously ODM power optimization will be disabled when MPO plane is
present due to technical challeges. This is mainly because ODM divides
pixel workload with respect to stream but MPO plane position and size
are arbitrary with respect to stream. The pixel processing workload of
an MPO plane is not guarenteed to be evenly distributed across DCN pipes.
For example if a plane is moved inside single ODM slice, all the
processing for the plane is distributed to the pipe in the current ODM
slice, while the other ODM slices don't need to process this plane. If
the plane is then moved to the middle crosing two ODM slices, each ODM
slice gets half of the workload. This is especially difficult when the
plane itself has a large source rect which can't be processed by single
DCN pipe. In this case we can't enable ODM power optimization when the
plane is only within one ODM slice.
[how]
To overcome the challeges, new pipe resource management is in place to
make sure a plane is validated with ODM power optimization support if
it can be validated regardless of its position and the same pipe
topology can be used regardless of the plane's position. When the plane
is moved outside current ODM slice, we will set recout to 0 so the pipe
can be idling without the need to update pipe topology. When the user
resizes a plane, it may result in downscaling ratio changes. When the
downscaling ratio is above single pipe's threshold, we will seamlessly
exit ODM power optimization and applies MPC combine to support the plane.
when downscaling ratio becomes smaller, we will seamlessly enter ODM
power optimization again. All these pipe transitions happen
automatically and quietly when the conditions are met without any visual
impacts to the user.

Previously the new minimal transition path was only used for windowed
MPO + ODM for plane scaling updates. However, we want to generalize the
transition for all cases whenever a non-seamless transition is detected
(such as for MPO -> SubVP + MPC).
To make this change we add pointers in the plane state, stream, and
pointers in the stream state to the dc_scratch state and backup and
restore these so the minimal transition can take place successfully.

Fixes potential null pointer dereference warnings in the
dc_dmub_srv_cmd_list_queue_execute() and dc_dmub_srv_is_hw_pwr_up()
functions.
In both functions, the 'dc_dmub_srv' variable was being dereferenced
before it was checked for null. This could lead to a null pointer
dereference if 'dc_dmub_srv' is null. The fix is to check if
'dc_dmub_srv' is null before dereferencing it.
Thus moving the null checks for 'dc_dmub_srv' to the beginning of the
functions to ensure that 'dc_dmub_srv' is not null when it is
dereferenced.
Found by smatch & thus fixing the below:
drivers/gpu/drm/amd/amdgpu/../display/dc/dc_dmub_srv.c:133 dc_dmub_srv_cmd_list_queue_execute() warn: variable dereferenced before check 'dc_dmub_srv' (see line 128)

[Why]
Observe error message "Can't retrieve aconnector in hpd_rx_irq_offload_work"
when boot up with a mst tbt4 dock connected. After analyzing, there are few
parts needed to be adjusted:
1. hpd_rx_offload_wq[].aconnector is not initialzed before the dmub outbox
hpd_irq handler get registered which causes the error message.
2. registeration of hpd and hpd_rx_irq event for usb4 dp tunneling is not
aligned with legacy interface sequence
[How]
Put DMUB_NOTIFICATION_HPD and DMUB_NOTIFICATION_HPD_IRQ handler
registration into register_hpd_handlers() to align other interfaces and
get hpd_rx_offload_wq[].aconnector initialized earlier than that.
Leave DMUB_NOTIFICATION_AUX_REPLY registered as it was since we need that
while calling dc_link_detect(). USB4 connection status will be proactively
detected by dc_link_detect_connection_type() in amdgpu_dm_initialize_drm_device()

During syncobj_eventfd_entry_func, dma_fence_chain_find_seqno may set
the fence to NULL if the given seqno is signaled and a later seqno has
already been submitted. In that case, the eventfd should be signaled
immediately which currently does not happen.
This is a similar issue to the one addressed by commit b19926d4f3a6
("drm/syncobj: Deal with signalled fences in drm_syncobj_find_fence.").
As a fix, if the return value of dma_fence_chain_find_seqno indicates
success but it sets the fence to NULL, we will assign a stub fence to
ensure the following code still signals the eventfd.

When waiting for a syncobj timeline point whose fence has not yet been
submitted with the WAIT_FOR_SUBMIT flag, a callback is registered using
drm_syncobj_fence_add_wait and the thread is put to sleep until the
timeout expires. If the fence is submitted before then,
drm_syncobj_add_point will wake up the sleeping thread immediately which
will proceed to wait for the fence to be signaled.
However, if the WAIT_AVAILABLE flag is used instead,
drm_syncobj_fence_add_wait won't get called, meaning the waiting thread
will always sleep for the full timeout duration, even if the fence gets
submitted earlier. If it turns out that the fence *has* been submitted
by the time it eventually wakes up, it will still indicate to userspace
that the wait completed successfully (it won't return -ETIME), but it
will have taken much longer than it should have.
To fix this, we must call drm_syncobj_fence_add_wait if *either* the
WAIT_FOR_SUBMIT flag or the WAIT_AVAILABLE flag is set. The only
difference being that with WAIT_FOR_SUBMIT we will also wait for the
fence to be signaled after it has been submitted while with
WAIT_AVAILABLE we will return immediately.

Since we cannot immediately capture the BO's and userptr, perform it in
2 stages. The immediate stage takes a reference to each BO and userptr,
while a delayed worker captures the contents and then frees the
reference.
This is required because in signaling context, no locks can be taken, no
memory can be allocated, and no waits on userspace can be performed.
With the delayed worker, all of this can be performed very easily,
without having to resort to hacks.
Changes since v1:
- Fix crash on NULL captured vm.
- Use ascii85_encode to capture BO contents and save some space.
- Add length to coredump output for each captured area.
Changes since v2:
- Dump each mapping on their own line, to simplify tooling.
- Fix null pointer deref in xe_vm_snapshot_free.
Changes since v3:
- Don't add uninitialized value to snap->ofs. (Souza)
- Use kernel types for u32 and u64.
- Move snap_mutex destruction to final vm destruction. (Souza)
Changes since v4:
- Remove extra memset. (Souza)

The devcoredump is done in fence signaling context. Because of this, we
cannot take any of the normal mutexes or we would invert.
Normal: Take vm->lock, dma_fence_wait()
Devcoredump: from dma_fence_wait() context, take vm->lock.
This doesn't work, and we only care about integrity, so take the locks
around additions and removals of vma's.

Add the flag XE_VM_BIND_FLAG_DUMPABLE to notify devcoredump that this
mapping should be dumped.
This is not hooked up, but the uapi should be ready before merging.
It's likely easier to dump the contents of the bo's at devcoredump
readout time, so it's better if the bos will stay unmodified after
a hang. The NEEDS_CPU_MAPPING flag is removed as requirement.

Persistent exec_queues delays explicit destruction of exec_queues
until they are done executing, but destruction on process exit
is still immediate. It turns out no UMD is relying on this
functionality, so remove it. If there turns out to be a use-case
in the future, let's re-add.

Commit 1fd4a5a36f9f ("drm/connector: Rename legacy TV property") failed
to update all the users of the struct drm_tv_connector_state mode field,
which resulted in a build failure in i915.
However, a subsequent commit in the same series reintroduced a mode
field in that structure, with a different semantic but the same type,
with the assumption that all previous users were updated.
Since that didn't happen, the i915 driver now compiles, but mixes
accesses to the legacy_mode field and the newer mode field, but with the
previous semantics.
This obviously doesn't work very well, so we need to update the accesses
that weren't in the legacy renaming commit.
