4b3c641b5f drm/amd/display: Fix stale buffer object (bo) use
Fixes stale buffer object (bo) usage for cursor plane

Cursor plane's bo operations are handled in DC code.
Currently, atomic_commit() does not handle bo operations
for cursor plane, as a result the bo assigned for cursor
plane in dm_plane_helper_prepare_fb() is not coherent
with the updates to the same made in dc code.This mismatch
leads to "bo" corruption and hence crashes during S3 entry.

This patch cleans up the code which was added as a hack
for 4.9 version only.

97028037a3 drm/amdgpu: Grab/put runtime PM references in atomic_commit_tail()
So, unfortunately I recently made the discovery that in the upstream
kernel, the only reason that amdgpu is not currently suffering from
issues with runtime PM putting the GPU into suspend while it's driving
displays is due to the fact that on most prime systems, we have sound
devices associated with the GPU that hold their own runtime PM ref for
the GPU.

What this means however, is that in the event that there isn't any kind
of sound device active (which can easily be reproduced by building a
kernel with sound drivers disabled), the GPU will fall asleep even when
there's displays active. This appears to be in part due to the fact that
amdgpu has not actually ever relied on it's rpm_idle() function to be
the only thing keeping it running, and normally grabs it's own power
references whenever there are displays active (as can be seen with the
original pre-DC codepath in amdgpu_display_crtc_set_config() in
amdgpu_display.c). This means it's very likely that this bug was
introduced during the switch over the DC.

So to fix this, we start grabbing runtime PM references every time we
enable a previously disabled CRTC in atomic_commit_tail(). This appears
to be the correct solution, as it matches up with what i915 does in
i915/intel_runtime_pm.c.

The one sideaffect of this is that we ignore the variable that the
pre-DC code used to use for tracking when it needed runtime PM refs,
adev->have_disp_power_ref. This is mainly because there's no way for a
driver to tell whether or not all of it's CRTCs are enabled or disabled
when we've begun committing an atomic state, as there may be CRTC
commits happening in parallel that aren't contained within the atomic
state being committed. So, it's safer to just get/put a reference for
each CRTC being enabled or disabled in the new atomic state.

For cases where the CRTC is inactive (DPMS off), where a modeset is not
required, yet the CRTC is still in the atomic state, we should not
attempt to update anything on it.

Previously, we were relying on the modereset_required() helper to check
the above condition. However, the function returns false immediately if
a modeset is not required, ignoring the CRTC's enable/active state
flags. The correct way to filter is by looking at these flags instead.

a2a330ad66 drm/amd/display: remove need of modeset flag for overlay planes (V2)
This patch is in continuation to the
"843e3c7 drm/amd/display: defer modeset check in dm_update_planes_state"
where we started to eliminate the dependency on
DRM_MODE_ATOMIC_ALLOW_MODESET to be set by the user space,
which as such is not mandatory.

After deferring, this patch eliminates the dependency on the flag
for overlay planes.

This has to be done in stages as its a pretty complex and requires thorough
testing before we free primary planes as well from dependency on modeset
flag.

V2: Simplified the plane type check.

3d777c82bd drm/amd/display: Disallow enabling CRTC without primary plane with FB
The below commit

    "drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2"

introduces a slight behavioral change to rmfb. Instead of disabling a crtc
when the primary plane is disabled, it now preserves it.

Since DC is currently not equipped to handle this we need to fail such
a commit, otherwise we might see a corrupted screen.

This is based on Shirish's previous approach but avoids adding all
planes to the new atomic state which leads to a full update in DC for
any commit, and is not what we intend.

Theoretically DM should be able to deal with states with fully populated planes,
even for simple updates, such as cursor updates. This should still be
addressed in the future.

a80aa93de1 drm/amd/display: Unify dm resume sequence into a single call
Merge amdgpu_dm_display_resume function into dm_resume,
as it is not called anywhere else anymore.

Initially the call was broken down into 2 functions for cursor corruption
issue. Now the issue is not visible, hence the dm_resume will perform
dm_display_resume in it.

ba9ca0886d drm/admgpu: fix mode_valid's return type
The method struct drm_connector_helper_funcs::mode_valid is defined
as returning an 'enum drm_mode_status' but the driver implementation
for this method uses an 'int' for it.

Fix this by using 'enum drm_mode_status' in the driver too.

f287765680 drm/amd/display: Disallow enabling CRTC without primary plane with FB
The below commit

    "drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2"

introduces a slight behavioral change to rmfb. Instead of disabling a crtc
when the primary plane is disabled, it now preserves it.

Since DC is currently not equipped to handle this we need to fail such
a commit, otherwise we might see a corrupted screen.

This is based on Shirish's previous approach but avoids adding all
planes to the new atomic state which leads to a full update in DC for
any commit, and is not what we intend.

Theoretically DM should be able to deal with states with fully populated planes,
even for simple updates, such as cursor updates. This should still be
addressed in the future.

df534fff0d drm/amd/display: Correct the plane enumeration order (v2)
The order of planes is given by the order they are enumerated
by kms.
Planes with a higher ID appears above planes with a lower ID.

Currently the planes are enumerated in the wrong order,
putting the nv12 only plane after the two RGBA planes.

This patch corrects the plane enumeration order such that all
the overlay planes are initialized first then the primary planes.

Due to this change in order the dc_add_plane_to_context() shall
receive the planes in reverse order hence this patch reverses
the parsing of planes in DM side itself.

v2: drop local reverse macro for upstream
