fab2cc8335 drm/amdgpu: add AMDGPU_GEM_CREATE_DISCARDABLE
Add a AMDGPU_GEM_CREATE_DISCARDABLE flag to note that the content of a BO
doesn't needs to be preserved during eviction.

KFD was already using a similar functionality for SVM BOs so replace the
internal flag with the new UAPI.

76818cdd11 drm/amd/display: add Coverage blend mode for overlay plane
According to the KMS man page, there is a
"Coverage" alpha blend mode that assumes the
pixel color values have NOT been pre-multiplied
and will be done when the actual blending to
the background color values happens.

Previously, this mode hasn't been enabled
in our driver and it was assumed that all
normal overlay planes are pre-multiplied
by default.

When a 3rd party app is used to input a image
in a specific format, e.g. PNG, as a source
of a overlay plane to blend with the background
primary plane, the pixel color values are not
pre-multiplied. So by adding "Coverage" blend
mode, our driver will support those cases.

Issue fixed: Overlay plane alpha channel blending is incorrect
Issue tracker: https://gitlab.freedesktop.org/drm/amd/-/issues/1769

Reference:
https://dri.freedesktop.org/docs/drm/gpu/drm-kms.html#plane-composition-properties

Adding Coverage support also enables IGT
kms_plane_alpha_blend Coverage subtests:
1. coverage-7efc
2. coverage-vs-premult-vs-constant

Changes
1. Add DRM_MODE_BLEND_COVERAGE blend mode capability
2. Add "pre_multiplied_alpha" flag for Coverage case
3. Read the correct flag and set the DCN MPCC
pre_multiplied register bit (only on overlay plane)

a0af5dbdc9 drm/amdkfd: simplify cpu hive assignment
CPU hive assignment currently assumes when a GPU hive is connected_to_cpu,
there is only one hive in the system.

Only assign CPUs to the hive if they are explicitly directly connected to
the GPU hive to get rid of the need for this assumption.

It's more efficient to do this when querying IO links since other non-CRAT
info has to be filled in anyways.  Also, stop re-assigning the
same CPU to the same GPU hive if it has already been done before.

e4b0eac3e6 drm/amd/display: Move FPU associated DCN30 code to DML folder
[why & how]
As part of the FPU isolation work documented in
https://patchwork.freedesktop.org/series/93042/, isolate
code that uses FPU in DCN30 to DML, where all FPU code
should locate.

66a1972037 drm/amd/display: Check zero planes for OTG disable W/A on clock change
[Why]
A display clock change hang can occur when switching between DIO and HPO
enabled modes during the optimize_bandwidth in dc_commit_state_no_check
call.

This happens when going from 4k120 8bpc 420 to 4k144 10bpc 444.

Display clock in the DIO case is 1200MHz, but pixel rate is 600MHz
because the pixel format is 420.

Display clock in the HPO case is less (800MHz?) because of ODM combine
which results in a smaller divider.

The DIO is still active in prepare but not active in the optimize which
results in the hang occuring.

During this change there are no planes on the stream so it's safe to
apply the workaround, but dpms_off = false and signal type is not
virtual.

[How]
Check for plane_count == 0, no planes on the stream.

It's easiest to check pipe->plane_state == NULL as an equivalent check
rather than trying to search for the stream status in the context
associated with the stream, so let's do that.

The primary, non MPO pipe should not have a NULL plane state.

ab144f0b4a drm/amd/display: Allow individual control of eDP hotplug support
[Why]
Second eDP can send display off notification through HPD
but DC isn't hooked up to handle. Some primary eDP panels
will toggle on/off incorrectly if it's enabled generically.

[How]
Extend the debug option to allow individually enabling hotplug
either the first eDP or the second eDP in a dual eDP system.

3f69ee66f5 drm/amd/display: clear request when release aux engine
[Why]
when driver and dmub request aux engine at the same time,
dmub grant the aux engine but driver fail. Then driver
release aux engine but doesn't clear the request bit.
Then aux engine will be occupied by driver forever.

[How]
When driver release aux engine, clear request bit as well.

[Why]
Some displays may need several link training attempts before
link training succeeds.

[How]
If training succeeds after falling back to lower link bandwidth,
retry at original link bandwidth instead of abandoning link training
whenever link bandwidth is less than stream bandwidth.

0ea917819d drm/i915/dsi: fix VBT send packet port selection for ICL+
The VBT send packet port selection was never updated for ICL+ where the
2nd link is on port B instead of port C as in VLV+ DSI.

First, single link DSI needs to use the configured port instead of
relying on the VBT sequence block port. Remove the hard-coded port C
check here and make it generic. For reference, see commit f915084edc
("drm/i915: Changes related to the sequence port no for") for the
original VLV specific fix.

Second, the sequence block port number is either 0 or 1, where 1
indicates the 2nd link. Remove the hard-coded port C here for 2nd
link. (This could be a "find second set bit" on DSI ports, but just
check the two possible options.)

Third, sanity check the result with a warning to avoid a NULL pointer
dereference.
