a135a1b4c4 drm/amd/display: Fix memory leaks in S3 resume
EDID parsing in S3 resume pushes new display modes
to probed_modes list but doesn't consolidate to actual
mode list. This creates a race condition when
amdgpu_dm_connector_ddc_get_modes() re-initializes the
list head without walking the list and results in  memory leak.

ea96b12aa4 drm/amd/display: handler not correctly checked at remove_irq_handler
[why]
handler is supposedly passed in as a function pointer;
however, the entire struct amdgpu_dm_irq_handler_data
gets from the list is used to check match.

[how]
use the interrupt_handler within amdgpu_dm_irq_handler_data
for checking match.

02ce73b01e drm/amd/display: Fix to be able to stop crc calculation
[Why]
Find out when we try to disable CRC calculation,
crc generation is still enabled. Main reason is
that dc_stream_configure_crc() will never get
called when the source is AMDGPU_DM_PIPE_CRC_SOURCE_NONE.

[How]
Add checking condition that when source is
AMDGPU_DM_PIPE_CRC_SOURCE_NONE, we should also call
dc_stream_configure_crc() to disable crc calculation.
Also, clean up crc window when disable crc calculation.

[Why]
With the addition of dc_lock acquire before dc_link_handle_hpd_rx_irq,
there will be a deadlock situation where commit state sends a request
for payload allocation on MST and wait for HPD to process DOWN_REP.

Move forward the MST message handling in handle_hpd_rx_irq so that
it will not rely on call to dc_link_handle_hpd_rx_irq.

e72868c4ea drm/amd/display: check cursor FB is linear
Previously we accepted non-linear buffers for the cursor plane. This
results in bad output, DC validation failures and oops.

Make sure the FB uses a linear layout in the atomic check function.

The GFX8- check is inspired from ac_surface_set_bo_metadata in Mesa.
The GFX9+ check comes from convert_tiling_flags_to_modifier.

3c4d55c9b9 drm/amd/display: turn DPMS off on connector unplug
[Why&How]

Set dpms off on the connector that was unplugged, for the side effect of
releasing some references held through deallocation of MST payload. This is
the expected behaviour for non MST devices as well.

1347385fe1 drm/amd/display: don't expose rotation prop for cursor plane
Setting any rotation on the cursor plane is ignored by amdgpu.
Because of DCE/DCN design, it's not possible to rotate the cursor.
Instead of displaying the wrong result, stop advertising the rotation
property for the cursor plane.

Now that we check all cursor plane properties in amdgpu_dm_atomic_check,
remove the TODO.

24f99d2b21 drm/amd/display: add cursor FB size check
This patch expands the cursor checks added in "drm/amd/display: add basic
atomic check for cursor plane" to also include a FB size check. Without
this patch, setting a FB smaller than max_cursor_size with an invalid
width would result in amdgpu error messages and a fallback to a 64-byte
width:

    [drm:hubp1_cursor_set_attributes [amdgpu]] *ERROR* Invalid cursor pitch of 100. Only 64/128/256 is supported on DCN.

Note that DC uses the word "pitch" when actually checking the FB width.
Indeed, the function handle_cursor_update does this:

    attributes.pitch = attributes.width;

In my tests, the cursor FB actually had a pitch of 512 bytes.

drm: Pass the full state to connectors atomic functions
The current atomic helpers have either their object state being passed as
an argument or the full atomic state.

The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.

Now that the CRTCs have been converted, let's move forward with the
connectors to provide a consistent interface.

The conversion was done using the coccinelle script below, and built tested
on all the drivers.

8976f73b67 drm/amd/display: Always get CRTC updated constant values inside commit tail
We recently improved our display atomic commit and tail sequence to
avoid some issues related to concurrency. One of the major changes
consisted of moving the interrupt disable and the stream release from
our atomic commit to our atomic tail (commit 6d90a208cfff
("drm/amd/display: Move disable interrupt into commit tail")) .
However, the new code introduced inside our commit tail function was
inserted right after the function
drm_atomic_helper_update_legacy_modeset_state(), which has routines for
updating internal data structs related to timestamps. As a result, in
certain conditions, the display module can reach a situation where we
update our constants and, after that, clean it. This situation generates
the following warning:

 amdgpu 0000:03:00.0: drm_WARN_ON_ONCE(drm_drv_uses_atomic_modeset(dev))

For fixing this issue we rely upon a refactor introduced on
drm_atomic_helper_update_legacy_modeset_state ("Remove the timestamping
constant update from drm_atomic_helper_update_legacy_modeset_state()")
which decouples constant values update from
drm_atomic_helper_update_legacy_modeset_state to a new helper.
Basically, this commit uses this new helper and place it right after our
release module to avoid a situation where our CRTC struct gets wrong
values.

If we use DCC modifiers this can increase the number of planes from

Since the code didn't update the format_info getfb2 would only ever
return 1 plane with a modifier for which userspace expects > 1.

This moves the format lookup to amdgpu_display.c so we do not have
