59d3191f14 drm/amd/display: don't call dm_pp_ function from an fpu block
Powerplay functions called from dm_pp_* functions tend to do a
mutex_lock which isn't safe to do inside a kernel_fpu_begin/end block as
those will disable/enable preemption.

Rearrange the dm_pp_get_clock_levels_by_type_with_voltage calls to make
sure they happen outside of kernel_fpu_begin/end.

634092b1b9 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.

0921c41e19 drm/amd/display: Fix negative cursor pos programming
[Why]
If the cursor pos passed from DM is less than the plane_state->dst_rect
top left corner then the unsigned cursor pos wraps around to a large
positive number since cursor pos is a u32.

There was an attempt to guard against this in hubp1_cursor_set_position
by checking the src_x_offset and src_y_offset and offseting the
cursor hotspot within hubp1_cursor_set_position.

However, the cursor position itself is still being programmed
incorrectly as a large value.

This manifests itself visually as the cursor disappearing or containing
strange artifacts near the middle of the screen on raven.

[How]
Don't subtract the destination rect top left corner from the pos but
add it to the hotspot instead. This happens before the pos gets
passed into hubp1_cursor_set_position.

This achieves the same result but avoids the subtraction wrap around.
With this fix the original cursor programming logic can be used again.

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.

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.

2010840b9b drm/amd/display: send pipe set command to dmcu when backlight is set
[Why]
Previously, a change removed code that would send a pipe set command
to dmcu each time the backlight was set, as it was thought to be
superfluous. However, it is possible for the backlight to be set
before a valid pipe has been set, which causes DMCU to hang after a
DPMS restore on some systems.

[How]
Send a pipe set command to DMCU prior to setting the backlight.

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.

5062b797db drm/amd/display: Don't re-program planes for DPMS changes
[Why]
There are opt1c lock warnings and CRTC read timeouts when running the
"igt@kms_plane@plane-position-hole-dpms-pipe-*" tests. These are
caused by trying to reprogram planes that are not in the current
context.

DPMS off removes the stream from the context. In this case:

new_crtc_state->active_changed = true
new_crtc_state->mode_changed = false

The planes are reprogrammed before the stream is removed from the
context because stream_state->mode_changed = false.

For DPMS adds the stream and planes back to the context:

new_crtc_state->active_changed = true
new_crtc_state->mode_changed = false

The planes are also reprogrammed here before the stream is added to the
context because stream_state->mode_changed = true. They were not
previously in the current context so warnings occur here.

[How]
Set stream_state->mode_changed = true when
new_crtc_state->active_changed = true too.

This prevents reprogramming before the context is applied in DC. The
programming will be done after the context is applied.

77476360f1 drm/amd/display: Disconnect mpcc when changing tg
[Why]
This fixes an mpc programming error for the following sequence of
atomic commits when pipe split is enabled:

Commit 1: CRTC0 (plane 4, plane 3)

Pipe 0: old_plane_state = A0, new_plane_state = A1,   new_tg = T0
Pipe 1: old_plane_state = B0, new_plane_state = B1,   new_tg = T0
Pipe 2: old_plane_state = A0, new_plane_state = A1,   new_tg = T0
Pipe 3: old_plane_state = B0, new_plane_state = B1,   new_tg = T0

Commit 2: CRTC0 (plane 3), CRTC1 (plane 2)

Pipe 0: old_plane_state = A1, new_plane_state = A2,   new_tg = T0
Pipe 1: old_plane_state = B1, new_plane_state = B2,   new_tg = T1
Pipe 2: old_plane_state = A1, new_plane_state = NULL, new_tg = NULL
Pipe 3: old_plane_state = B1, new_plane_state = NULL, new_tg = NULL

In the second commit the assertion for mpcc in use is hit because
mpcc disconnect never occurs for pipe 1. This is because the stream
changes for pipe 1 and the opp_list is empty.

This sequence occurs when running the
"igt@kms_plane_multiple@atomic-pipe-A-tiling-none" test with two
displays connected.

[How]
Expand the reset condition to include:

"old_pipe_ctx->stream_res.tg != new_pipe_ctx->stream_res.tg"

...but only when the plane state is non-NULL for both old and new.
