This is recommended by HW designers. Previously when it was set to 1,
the PDE walk error in VM fault will be treated as
PERMISSION_OR_INVALID_PAGE_FAULT rather than usually expected OTHER_FAULT.
As a result, the retry control in VM_CONTEXT*_CNTL will change accordingly.

The above behavior is kind of abnormal. Furthermore, the
PDE_FAULT_CLASSIFICATION == 1 feature was targeted for very old ASICs
and it never made it way to production. Therefore, we should set it to 0.

74aa7bd4c6 drm/amd/display: Make stream commits call into DC only once
[Why]
dc_commit_updates_for_stream is called twice per stream: once
with the flip data and once will all other data. This causes
problems when these DC calls have different numbers of planes

For example, a commit with a pageflip on plane A and a
non-pageflip change on plane B will first call
into DC with just plane A, causing plane B to be
disabled. Then it will call into DC with both planes,
re-enabling plane B

[How]
Merge flip and full into a single bundle

Apart from the single DC call, the logic should not be
changed by this patch

The wait_for_vblank boolean in commit_tail was passed by reference

flip, it would disable vblank waits on all subsequent flips.

This made the behaviour depend on crtc order in a non-intuitive way,

4bc46da4a3 drm/amd/display: Reset planes that were disabled in init_pipes
[Why]
Seamless boot tries to reuse planes that were enabled for the first
commit applied.

In the case where Raven is booting with two monitors connected and the
first commit contains two streams the screen corruption would occur
because the second stream was trying to re-use a tg and plane that
weren't previously enabled.

The state on the first commit looks something like the following:

TG0: enabled=1
TG1: enabled=0
TG2: enabled=0
TG3: enabled=0

New state: pipe=0, stream=0,    plane=0,       new_tg=0
New state: pipe=1, stream=1,    plane=1,       new_tg=1
New state: pipe=2, stream=NULL, plane=NULL,    new_tg=NULL
New state: pipe=3, stream=NULL, plane=NULL,    new_tg=NULL

Only one plane/tg is setup before we enter accelerated mode so
we really want to disabling everything but that first plane.

[How]

Check if the stream is not NULL and if the tg is enabled before
deciding whether to skip the plane disable.

Also ensure we're also disabling on the current state's pipe_ctx so
we don't overwrite the fields in the new pending state.

7b19bba58f drm/amd/display: Use vrr friendly pageflip throttling in DC.
In VRR mode, keep track of the vblank count of the last
completed pageflip in amdgpu_crtc->last_flip_vblank, as
recorded in the pageflip completion handler after each
completed flip.

Use that count to prevent mmio programming a new pageflip
within the same vblank in which the last pageflip completed,
iow. to throttle pageflips to at most one flip per video
frame, while at the same time allowing to request a flip
not only before start of vblank, but also anywhere within
vblank.

The old logic did the same, and made sense for regular fixed
refresh rate flipping, but in vrr mode it prevents requesting
a flip anywhere inside the possibly huge vblank, thereby
reducing framerate in vrr mode instead of improving it, by
delaying a slightly delayed flip requests up to a maximum
vblank duration + 1 scanout duration. This would limit VRR
usefulness to only help applications with a very high GPU
demand, which can submit the flip request before start of
vblank, but then have to wait long for fences to complete.

With this method a flip can be both requested and - after
fences have completed - executed, ie. it doesn't matter if
the request (amdgpu_dm_do_flip()) gets delayed until deep
into the extended vblank due to cpu execution delays. This
also allows clients which want to regulate framerate within
the vrr range a much more fine-grained control of flip timing,
a feature that might be useful for video playback, and is
very useful for neuroscience/vision research applications.

In regular non-VRR mode, retain the old flip submission
behavior. This to keep flip scheduling for fullscreen X11/GLX
OpenGL clients intact, if they use the GLX_OML_sync_control
extensions glXSwapBufferMscOML(, ..., target_msc,...) function
with a specific target_msc target vblank count.

glXSwapBuffersMscOML() or DRI3/Present PresentPixmap() will
not flip at the proper target_msc for a non-zero target_msc
if VRR mode is active with this patch. They'd often flip one
frame too early. However, this limitation should not matter
much in VRR mode, as scheduling based on vblank counts is
pretty futile/unusable under variable refresh duration
anyway, so no real extra harm is done.

According to some testing already done with this patch by
Nicholas on top of my tests, IGT tests didn't report any
problems. If fixes stuttering and flickering when flipping
at rates below the minimum vrr refresh rate.

672e78cab8 drm/amd/display: Pass app_tf by value rather than by reference
Clang warns when an expression that equals zero is used as a null
pointer constant (in lieu of NULL):

drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:4435:3:
warning: expression which evaluates to zero treated as a null pointer
constant of type 'const enum color_transfer_func *'
[-Wnon-literal-null-conversion]
                TRANSFER_FUNC_UNKNOWN,
                ^~~~~~~~~~~~~~~~~~~~~
1 warning generated.

This warning is caused by commit bb47de7366 ("drm/amdgpu: Set FreeSync
state using drm VRR properties") and it could be solved by using NULL
instead of TRANSFER_FUNC_UNKNOWN or casting TRANSFER_FUNC_UNKNOWN as a
pointer. However, after looking into it, there doesn't appear to be a
good reason to pass app_tf by reference as it is never mutated along the
way. This is the only code path in which app_tf is used:

mod_freesync_build_vrr_infopacket ->
    build_vrr_infopacket_v2 ->
        build_vrr_infopacket_fs2_data

Neither mod_freesync_build_vrr_infopacket or build_vrr_infopacket_v2
modify app_tf's value and build_vrr_infopacket_fs2_data expects just
the value so we can avoid dereferencing anything by just passing in
app_tf's value to mod_freesync_build_vrr_infopacket and
build_vrr_infopacket_v2.

There is no functional change because build_vrr_infopacket_fs2_data
doesn't do anything if TRANSFER_FUNC_UNKNOWN is passed to it, the same
as not calling build_vrr_infopacket_fs2_data at all like before this
change when NULL was used for app_tf.

dcd5fb82ff drm/amd/display: Fix reference counting for struct dc_sink.
Reference counting in amdgpu_dm_connector for amdgpu_dm_connector::dc_sink
and amdgpu_dm_connector::dc_em_sink as well as in dc_link::local_sink seems
to be out of shape. Thus make reference counting consistent for these
members and just plain increment the reference count when the variable
gets assigned and decrement when the pointer is set to zero or replaced.
Also simplify reference counting in selected function sopes to be sure the
reference is released in any case. In some cases add NULL pointer check
before dereferencing.
At a hand full of places a comment is placed to stat that the reference
increment happened already somewhere else.

This actually fixes the following kernel bug on my system when enabling
display core in amdgpu. There are some more similar bug reports around,
so it probably helps at more places.

f180bf12ac drm/nouveau/svm: new ioctl to migrate process memory to GPU memory
This add an ioctl to migrate a range of process address space to the
device memory. On platform without cache coherent bus (x86, ARM, ...)
this means that CPU can not access that range directly, instead CPU
will fault which will migrate the memory back to system memory.

This is behind a staging flag so that we can evolve the API.

eeaf06ac1a drm/nouveau/svm: initial support for shared virtual memory
This uses HMM to mirror a process' CPU page tables into a channel's page
tables, and keep them synchronised so that both the CPU and GPU are able
to access the same memory at the same virtual address.

While this code also supports Volta/Turing, it's only enabled for Pascal
GPUs currently due to channel recovery being unreliable right now on the
later GPUs.

bfe91afaca drm/nouveau: prepare for enabling svm with existing userspace interfaces
For a channel to make use of SVM features, it requires a different GPU MMU
configuration than we would normally use, which is not desirable to switch
to unless a client is actively going to use SVM.

In order to supporting SVM without more extensive changes to the userspace
interfaces, the SVM_INIT ioctl needs to replace the previous configuration
safely.

The only way we can currently do this safely, accounting for some unlikely
failure conditions, is to allocate the new VMM without destroying the last
one, and prioritising the SVM-enabled configuration in the code that cares.

This will get cleaned up again further down the track.

ab2ee9ffa3 drm/nouveau/mmu/gp100-: support vmms with gcc/tex replayable faults enabled
Some GPU units are capable of supporting "replayable" page faults, where
the execution unit will wait for SW to fixup GPU page tables rather than
triggering a channel-fatal fault.

This feature isn't useful (it's harmful, even) unless something like HMM
is being used to manage events appearing in the replayable fault buffer,
so, it's disabled by default.

This commit allows a client to request it be enabled.

71871aa6df drm/nouveau/mmu/gp100-: add privileged methods for fault replay/cancel
Host methods exist to do at least some of what we need, but we are not
currently pushing replay/cancels through a channel like UVM does as it's
not clear whether it's necessary in our case (UVM also updates PTEs with
the GPU).

UVM also pushes a software method for fault cancels on Pascal, seemingly
because the host methods don't appear to be sufficient.  If/when we want
to push the replay/cancel on the GPU, we can re-purpose the cancellation
code here to implement that swmthd.

Keep it simple for now, until we figure out exactly what we need here.

2606f29162 drm/nouveau/mmu: support initialisation of client-managed address-spaces
NVKM is currently responsible for managing the allocation of a client's
GPU address-space, but there's various use-cases (ie. HMM address-space
mirroring) where giving a client more direct control is desirable.

This commit allows for a VMM to be created where the area allocated for
NVKM is limited to a client-specified window, the remainder of address-
space is controlled directly by the client.

Leaving a window is necessary to support various internal requirements,
but also to support existing allocation interfaces as not all of the HW
is capable of working with a HMM allocation.

bcb35dad1d drm/amd/powerplay/smu10_hwmgr: use struct_size() in kzalloc()
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    struct boo entry[];
};

size = sizeof(struct foo) + count * sizeof(struct boo);
instance = kzalloc(size, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);

Notice that, in this case, variable table_size is not necessary, hence
it is removed.

This code was detected with the help of Coccinelle.

d6001aed26 drm/amd/display: Refactor for setup periodic interrupt.
[Why]

[How]
1. DM convert delta time to lines number and dc will calculate the

2. hwss calculates the start point as per line offset.

d8d2f174bc drm/amd/display: Clear stream->mode_changed after commit
[Why]
The stream->mode_changed flag can persist in the following sequence
of atomic commits:

Commit 1:
Enable CRTC0 (mode_changed = true), Enable CRTC1 (mode_changed = true)

Commit 2:
Disable CRTC1 (mode_changed = false)

In this sequence we want to keep the exiting CRTC0 but it's not in the
atomic state for the commit since it hasn't been modified. In this case
the stream->mode_changed flag persists as true and we don't re-program
the planes for the existing stream.

[How]
The flag needs to be cleared and it makes the most sense to do it within
DC after the state has been committed. Nothing following dc_commit_state
should think that the stream's mode has changed.

80c218d56e drm/amd/display: Do cursor updates after stream updates
[Why]
Cursor updates used to happen after vblank/flip/stream updates before
the stream update refactor. They now happen before stream updates
which means that they're not going to be synced with fb changes

within the same commit.

6836d23916 drm/amd/display: Fix update type mismatches in atomic check
[Why]
Whenever a stream or plane is added or removed from the context the
pointer will change from old to new. We set lock and validation
needed in these cases. But not all of these cases match update_type
from dm_determine_update_type_for_commit - an example being overlay
plane updates.

There are warnings for a few of these cases that should be fixed.

[How]
We can closer align to DC (and lock_and_validation_needed) by
comparing stream and plane pointers.

Since the old stream/old plane state is never freed until sometime
after the commit tail work finishes we are guaranteed to never get
back the same block of memory when we remove and create a stream or
plane state in the same commit.

2d9e64317e drm/amd/display: Fix wrong z-order when updating overlay planes
[Why]
If a commit updates an overlay plane via the legacy plane IOCTL
then the only plane in the state will be the overlay plane.

Overlay planes need to be added first to the DC context, but in the
scenario above the plane will be added last. This will result in wrong
z-order during rendering.

[How]
If any non-cursor plane has been updated then the rest of the
non-cursor planes should be added to the CRTC state.

The cursor plane doesn't need to be included for stream updates and
locking it will cause performance issues. It should be ignored.

DC requires that the surface count passed during stream updates
be the number of surfaces currently on the stream to enable fast
updates. This previously wasn't the case without this patch, so this
also allows this optimization to occur.

240d09d070 drm/amd/display: Ungate stream before programming registers
[Why]
Certain tests fail after a fresh reboot. This is caused by writing to
registers prior to ungating the stream we're trying to program.

[How]
Make sure the stream is ungated before writing to its registers.
This also enables power-gating plane resources before init_hw
initializes them.
Additionally, this does some refactoring to move gating/ungating
from enable/disable_plane functions to where stream resources are
enabled/disabled.

Job creation already fails with -ENOENT when entity->rq is NULL,
so jobs cannot be pushed. Without a rq there is no scheduler to
pop jobs, and rq selection already does the right thing with a
list of length 0.

So the operations we need to fix are:
  - Creation, do not set rq to rq_list[0] if the list can have length 0.
  - Do not flush any jobs when there is no rq.
  - On entity destruction handle the rq = NULL case.
  - on set_priority, do not try to change the rq if it is NULL.

69ef943dbc drm: Use array_size() when creating lease
Passing an object_count of sufficient size will make
object_count * 4 wrap around to be very small, then a later function
will happily iterate off the end of the object_ids array.  Using
array_size() will saturate at SIZE_MAX, the kmalloc() will fail and
we'll return an -ENOMEM to the norty userspace.

Theoretically, gfx ring doorbells should come before all MEC doorbells
to be consistent with the design. However, since the doorbell
allocations are agreed by all and we are not free to change them, also
considering the kernel MEC ring doorbells which are before gfx ring
doorbells are not used often, we compromise by leaving the doorbell

e8a8fedd57 drm/i915: Block fbdev HPD processing during suspend
When resuming, we check whether or not any previously connected
MST topologies are still present and if so, attempt to resume them. If
this fails, we disable said MST topologies and fire off a hotplug event
so that userspace knows to reprobe.

However, sending a hotplug event involves calling
drm_fb_helper_hotplug_event(), which in turn results in fbcon doing a
connector reprobe in the caller's thread - something we can't do at the
point in which i915 calls drm_dp_mst_topology_mgr_resume() since
hotplugging hasn't been fully initialized yet.

This currently causes some rather subtle but fatal issues. For example,
on my T480s the laptop dock connected to it usually disappears during a
suspend cycle, and comes back up a short while after the system has been
resumed. This guarantees pretty much every suspend and resume cycle,
drm_dp_mst_topology_mgr_set_mst(mgr, false); will be caused and in turn,
a connector hotplug will occur. Now it's Rute Goldberg time: when the
connector hotplug occurs, i915 reprobes /all/ of the connectors,
including eDP. However, eDP probing requires that we power on the panel
VDD which in turn, grabs a wakeref to the appropriate power domain on
the GPU (on my T480s, this is the PORT_DDI_A_IO domain). This is where
things start breaking, since this all happens before
intel_power_domains_enable() is called we end up leaking the wakeref
that was acquired and never releasing it later. Come next suspend/resume
cycle, this causes us to fail to shut down the GPU properly, which
causes it not to resume properly and die a horrible complicated death.

(as a note: this only happens when there's both an eDP panel and MST
topology connected which is removed mid-suspend. One or the other seems
to always be OK).

We could try to fix the VDD wakeref leak, but this doesn't seem like
it's worth it at all since we aren't able to handle hotplug detection
while resuming anyway. So, let's go with a more robust solution inspired
by nouveau: block fbdev from handling hotplug events until we resume
fbdev. This allows us to still send sysfs hotplug events to be handled
later by user space while we're resuming, while also preventing us from
actually processing any hotplug events we receive until it's safe.

This fixes the wakeref leak observed on the T480s and as such, also
fixes suspend/resume with MST topologies connected on this machine.

Changes since v2:
* Don't call drm_fb_helper_hotplug_event() under lock, do it after lock
  (Chris Wilson)
* Don't call drm_fb_helper_hotplug_event() in
  intel_fbdev_output_poll_changed() under lock (Chris Wilson)
* Always set ifbdev->hpd_waiting (Chris Wilson)

drm/komeda: fix build with drm_modeset_helper.h update
With drmP.h removed from drm_modeset_helper.h the build of
komeda filed as reported by linux-next

Add missing include files to fix build.
For the files touched group include files and sort them.

The fix was tested on a tree with drm-misc-next merged.
And the patch was also tested to work without drm-misc-next merged.

16065fcdd1 drm/virtio: do NOT reuse resource ids
Bisected guest kernel changes crashing qemu.  Landed at
"6c1cd97bda drm/virtio: fix resource id handling".  Looked again, and
noticed we where not only leaking *some* ids, but *all* ids.  The old
code never ever called virtio_gpu_resource_id_put().

So, commit 6c1cd97bda effectively makes the linux kernel starting
re-using IDs after releasing them, and apparently virglrenderer can't
deal with that.  Oops.

This patch puts a temporary stopgap into place for the 5.0 release.

38f070eb12 drm/tegra: Changes for v5.1-rc1
This set of changes starts of with some refactoring of the CEC support
 to make it reusable on Tegra210 and later. Following are a couple of
 fixes for HDMI audio support (via HDA).
 
 The bulk here is a set of preparatory patches working towards enabling
 Tegra186 support for host1x and VIC. Additional patches will be needed
 to fully enable this, but they're not quite ready yet.
 
 To round things off, this also adds support for configuring the SOR
 crossbar using device tree, and fixes a couple of job-related issues in
 the host1x code.

82abf33766 drm/sched: Always trace the dependencies we wait on, to fix a race.
The entity->dependency can go away completely once we've called
drm_sched_entity_add_dependency_cb() (if the cb is called before we
get around to tracing).  The tracepoint is more useful if we trace
every dependency instead of just ones that get callbacks installed,
anyway, so just do that.

Fixes any easy-to-produce OOPS when tracing the scheduler on V3D with
