be1ac692c0 drm/amd/display: Fix DPIA outbox timeout after S3/S4/reset
[Why]
The HW interrupt gets disabled after S3/S4/reset so we don't receive
notifications for HPD or AUX from DMUB - leading to timeout and
black screen with (or without) DPIA links connected.

[How]
Re-enable the interrupt after S3/S4/reset like we do for the other
DC interrupts.

Guard both instances of the outbox interrupt enable or we'll hang
during restore on ASIC that don't support it.

69cb56290d drm/amd/display: Use oriented source size when checking cursor scaling
dm_check_crtc_cursor() doesn't take into account plane transforms when
calculating plane scaling, this can result in false positives.

For example, if there's an output with resolution 3840x2160 and the
output is rotated 90 degrees, CRTC_W and CRTC_H will be 3840 and 2160,
respectively, but SRC_W and SRC_H will be 2160 and 3840, respectively.

Since the cursor plane usually has a square buffer attached to it, the
dm_check_crtc_cursor() will think that there's a scale factor mismatch
even though there isn't really.

This fixes an issue where kwin fails to use hardware plane transforms.

Changes since version 1:
- s/orientated/oriented/g

7089784873 drm/amdgpu/display: Only set vblank_disable_immediate when PSR is not enabled
[Why]
PSR currently relies on the kernel's delayed vblank on/off mechanism
as an implicit bufferring mechanism to prevent excessive entry/exit.

Without this delay the user experience is impacted since it can take
a few frames to enter/exit.

[How]
Only allow vblank disable immediate for DC when psr is not supported.

Leave a TODO indicating that this support should be extended in the
future to delay independent of the vblank interrupt.

6d63fcc2a3 drm/amd/display: Reset link encoder assignments for GPU reset
[Why]
A warning appears in the log on GPU reset for
link_enc_cfg_link_encs_assign for the following condition:

ASSERT(state->res_ctx.link_enc_cfg_ctx.link_enc_assignments[i].valid == false);

This is not expected behavior and may result in link encoders being
incorrectly assigned.

[How]
The dc->current_state is backed up into dm->cached_dc_state before
we commit 0 streams.

DC will clear link encoder assignments on the real state but the
changes won't propagate over to the copy we made before the
0 streams commit.

DC expects that link encoder assignments are *not* valid
when committing a state, so as a workaround it needs to be cleared
before passing it back into DC.

6984fa418b drm/amd/display: Set plane update flags for all planes in reset

We're only setting the flags on stream[0]'s planes so this logic fails

This can cause a page flip timeout with multiple displays in the

[How]
Index into the stream_status array using the stream index - it's a 1:1
mapping.

85fb8bb9d4 drm/amd/display: Run full global validation in dc_commit_state
[Why]
Dynamic link encoder assignment expects that it can modify DC
current_state and the links associated with the incoming state when
performing full validation.

This does not align with our actual synchronization constraints
in DM's atomic_check.

[How]
Since link encoder assignment only happens as part of full validation
we can just use fast validation as part of atomic_check instead.

This satisfy's DC interface requirements and skips the DML calculations
needed for pipe programming - hopefully speeding up things a little bit
to offset the cost of double validation during stream modification.

We already do this as part of dc_commit_updates_for_stream()
with validate_bandwidth(), so extend this to dc_commit_state() as
well.

d82b3266ef drm/amd/display: Don't lock connection_mutex for DMUB HPD
[Why]
Per DRM spec we only need to hold that lock when touching
connector->state - which we do not do in that handler.

Taking this locking introduces unnecessary dependencies with other
threads which is bad for performance and opens up the potential for
a deadlock since there are multiple locks being held at once.

[How]
Remove the connection_mutex lock/unlock routine and just iterate over
the drm connectors normally. The iter helpers implicitly lock the
connection list so this is safe to do.

DC link access also does not need to be guarded since the link
table is static at creation - we don't dynamically add or remove links,
just streams.

a550bb165b drm/amd/display: dsc engine not disabled after unplug dsc mst hub
[WHY]
If timing and bpp of displays on mst hub are not changed,
pbn, slot_num for displays should not be changed. Linux
user mode may initiate atomic_check with different display
configuration after set mode finished. This will call to
amdgpu_dm to re-compute payload, slot_num of displays and
saved to dm_connect_state. stream->timing.flags.dsc, pbn,
slot_num are updated to values which may be different from
that were used for set mode. when dsc hub with 3 4k@60hz dp
connected, 3 dsc engines are enabled. timing.flags.dsc = 1.
timing.flags.dsc are changed to 0 due to atomic check. when
dsc hub is unplugged, amdgpu driver check timing.flags.dsc
for last mode set and find out flags.dsc = 0, then does not
disable dsc.

[HOW]
check status of  displays on dsc mst hubs. re-compute pbn,
slot_num, timing.flags.dsc only if there is mode, connect
or enable/disable change.

tl;dr ChromeOS uses the atomic interface for everything except the cursor. This

652de07add drm/amd/display: Fully switch to dmub for all dcn21 asics
[Why]
On renoir usb-c port stops functioning on resume after f/w update.
New dmub firmware caused regression due to conflict with dmcu.
With new dmub f/w dmcu is superseded and should be disabled.

[How]
- Disable dmcu for all dcn21.

Check dmesg for dmub f/w version.
The old firmware (before regression):
[drm] DMUB hardware initialized: version=0x00000001
All other versions require this patch for renoir.

9470620e99 drm/amd/display: Enable PSR by default on newer DCN
[Why]
For optimal power savings on panels that can support it.

This was previously left disabled by default because of issues with
compositors that do not pageflip and scan out directly to the
frontbuffer.

For these compositors we now have detection methods that wait for x
number of pageflips after a full update - triggered by a buffer or
format change typically.

This may introduce bugs or new cases not tested by users so this is
only currently targeting newer DCN.

[How]
Add code in DM to set PSR state by default for newer DCN while falling
back to the feature mask for older.

Add a global debug flag that can be set to disable it for either.

d1bfbe8a32 amd/display: check cursor plane matches underlying plane
The current logic checks whether the cursor plane blending
properties match the primary plane's. However that's wrong,
because the cursor is painted on all planes underneath. If
the cursor is over the primary plane and the overlay plane,
it's painted on both pipes.

Iterate over the CRTC planes and check their scaling match
the cursor's.

[why]
1. HPD callback function has deadlock problem
2. HPD status is not assigned
3. There is crash due to null pointer
4. link_enc is NULL in DPIA case

[How]
1. Fix deadlock problem by moving it out of the
   drm_modeset_lock
2. Assign HPD status from the notify of outbox
   from dmub FW
3. Fix the crash by checking if pin or enc exists
4. Use link_enc_cfg_get_link_enc_used_by_link to

[Why]
To process SET_CONFIG transactions with DMUB using inbox1 and
outbox1 mail boxes.

[How]
1) DMUB posts SET_CONFIG reply as an Outbox1 message of type
   DMUB_OUT_CMD__SET_CONFIG_REPLY.
2) The dmub async to sync mechanism for AUX is modified to accommodate
   SET_CONFIG commands for both command issue and reply code paths.

1d789535a0 drm/amdgpu: convert IP version array to include instances
Allow us to query instances versions more cleanly.

Instancing support is not consistent unfortunately. SDMA is a
good example.  Sienna cichlid has 4 total SDMA instances, each
enumerated separately (HWIDs 42, 43, 68, 69).  Arcturus has 8
total SDMA instances, but they are enumerated as multiple
instances of the same HWIDs (4x HWID 42, 4x HWID 43).  UMC
is another example.  On most chips there are multiple
instances with the same HWID.  This allows us to support both
forms.

v2: rebase
v3: clarify instancing support

655c167edc drm/amd/display: Fix wrong format specifier in amdgpu_dm.c
[Why]
Currently, the 32bit kernel build fails due to an incorrect string
format specifier. ARRAY_SIZE() returns size_t type as it uses sizeof().
However, we specify it in a string as %ld. This causes a compiler error
and causes the 32bit build to fail.

[How]
Change the %ld to %zu as size_t (which sizeof() returns) is an unsigned
integer data type. We use 'z' to ensure it also works with 64bit build.
