dbb7898ac1 drm/amd/display: Drop SOC bounding box hookup in DM/DC
[Why]
There aren't any ASIC where we use these binaries and they aren't
useful for future use since it's inconvenient to extend and maintain
these structures.

[How]
Drop the support from DM and DC for now.

a0ffc3fd67 drm/amd/display: Report Freesync to vrr_range debugfs entry in DRM
[Why]
Since Linux 5.9.0, DRM has provided vrr_range debugfs for
all connectors. Reporting Freesync capability to vrr_range
debugfs entry registered in Linux DM no longer works.

[How]
Report min/max vertical frequency to vrr_range debugfs entrry
created by DRM connectors. Remove vrr_range debugfs entry from
Linux DM.

Resolve the conflict by picking the initialization value from amd from

98ab5f3513 drm/amd/display: Fix deadlock during gpu reset v3
[Why]
during idle optimizations we acquire the dc_lock, this lock is also
acquired during gpu_reset so we end up hanging the system due to a
deadlock

[How]
If we are in gpu reset:
 - disable idle optimizations and skip calls to the dc function

v2: skip idle optimizations calls
v3: add guard for DCN

[Why]
We can only use this feature when the display is idle. When active vblank
irq count is 0 we know all the displays are idle.

[How]
-Add a active vblank irq counter
-Update the counter when we enable/disable vblank irq
-if vblank irq count is 0 we can consider mall stutter

6ca2ab8086 drm: automatic legacy gamma support
To support legacy gamma ioctls the drivers need to set
drm_crtc_funcs.gamma_set either to a custom implementation or to
drm_atomic_helper_legacy_gamma_set. Most of the atomic drivers do the
latter.

We can simplify this by making the core handle it automatically.

Move the drm_atomic_helper_legacy_gamma_set() functionality into
drm_color_mgmt.c to make drm_mode_gamma_set_ioctl() use
drm_crtc_funcs.gamma_set if set or GAMMA_LUT property if not.

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.

03a6636730 drm/amd/display: use FB pitch to fill dc_cursor_attributes
Instead of relying on pitch (in pixels) == width, use the FB pitch. This
is less confusing to readers, and works correctly if we ever support FBs
with a pitch (in pixels) != width.

This also makes the code symmetrical with fill_plane_buffer_attributes.

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.

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 6d90a208cf
("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
issues when DC is not compiled.
