Merge drm/drm-next into drm-misc-next
drm/drm-next has a build fix for the NewVision NV3052C panel
(drivers/gpu/drm/panel/panel-newvision-nv3052c.c), which needs to be
merged back to drm-misc-next, as it was failing to build there.

9e12b5947b Revert "drm/amd/display: Pass HostVM enable flag into DCN3.1 DML"
This reverts commit 863fa85e6a.

While we were testing DCN3.1 with a hub, we noticed that only one of 2
connected displays lights up when using some specific display
resolution. In summary, this was the setup:

1. Displays:
 * Sharp LQ156M1JW26 (eDP): 1080@240
 * BENQ SW320 (DP): 4k@60
 * BENQ EX3203R (DP): 4k@60
2. Hub: Club3D CSV-7300
3. ASIC: DCN3.1

After bisecting this issue, we figured out the commit mentioned above
introduced this issue. We are investigating why this patch introduced
this regression, but we need to revert it for now.

e4f1541caf drm/amd/display: don't ignore alpha property on pre-multiplied mode
"Pre-multiplied" is the default pixel blend mode for KMS/DRM, as
documented in supported_modes of drm_plane_create_blend_mode_property():
https://cgit.freedesktop.org/drm/drm-misc/tree/drivers/gpu/drm/drm_blend.c

In this mode, both 'pixel alpha' and 'plane alpha' participate in the
calculation, as described by the pixel blend mode formula in KMS/DRM
documentation:

out.rgb = plane_alpha * fg.rgb +
          (1 - (plane_alpha * fg.alpha)) * bg.rgb

Considering the blend config mechanisms we have in the driver so far,
the alpha mode that better fits this blend mode is the
_PER_PIXEL_ALPHA_COMBINED_GLOBAL_GAIN, where the value for global_gain
is the plane alpha (global_alpha).

With this change, alpha property stops to be ignored. It also addresses
Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1734

v2:
 * keep the 8-bit value for global_alpha_value (Nicholas)
 * correct the logical ordering for combined global gain (Nicholas)
 * apply to dcn10 too (Nicholas)

2513ed4f93 drm/amd/display: do not wait for mpc idle if tg is disabled
[Why]
When booting, the driver waits for the MPC idle bit to be set as part of
pipe initialization. However, on some systems this occurs before OTG is
enabled, and since the MPC idle bit won't be set until the vupdate
signal occurs (which requires OTG to be enabled), this never happens and
the wait times out. This can add hundreds of milliseconds to the boot
time.

Do not wait for mpc idle if tg is disabled

Adding FPU protection avoids context switch and probable loss of vba context

4052287a75 amd/display: set backlight only if required
[Why]
comparing pwm bl values (coverted) with user brightness(converted)
levels in commit_tail leads to continuous setting of backlight via dmub
as they don't to match.
This leads overdrive in queuing of commands to DMCU that sometimes lead
to depending on load on DMCU fw:

"[drm:dc_dmub_srv_wait_idle] *ERROR* Error waiting for DMUB idle: status=3"

[How]
Store last successfully set backlight value and compare with it instead
of pwm reads which is not what we should compare with.

f4346fb3ed drm/amd/display: Fix allocate_mst_payload assert on resume
[Why]
On resume we do link detection for all non-MST connectors.
MST is handled separately. However the condition for telling
if connector is on mst branch is not enough for mst hub case.
Link detection for mst branch link leads to mst topology reset.
That causes assert in dc_link_allocate_mst_payload()

[How]
Use link type as indicator for mst link.

In init_hw() we call init_pipes() before enabling power gating.
init_pipes() tries to power gate dsc but it may fail because
required force-ons are not released yet.

set the v_total_max and min to nominal. We also cleanup after we exit
the game.

[How]
It calles populate_dml_pipes which uses doubles to initialize.
Adding FPU protection avoids context switch and probable loss of vba context
as there is potential contention while drm debug logs are enabled.

9696679bf7 drm/amd/display: remove DC_FP_* wrapper from dml folder
FPU documentation states that developers must not use DC_FP_START/END
inside dml files, but use this macro to wrap calls to FPU functions in
dc folder (outside dml folder). Therefore, this patch removes DC_FP_*
wrappers from dml folder and wraps calls for these FPU operations
outside dml, as required.

8f3286942f amd/display: set backlight only if required
[Why]
comparing pwm bl values (coverted) with user brightness(converted)
levels in commit_tail leads to continuous setting of backlight via dmub
as they don't to match.
This leads overdrive in queuing of commands to DMCU that sometimes lead
to depending on load on DMCU fw:

"[drm:dc_dmub_srv_wait_idle] *ERROR* Error waiting for DMUB idle: status=3"

[How]
Store last successfully set backlight value and compare with it instead
of pwm reads which is not what we should compare with.

c4af42b4eb drm/amd/display: Fix allocate_mst_payload assert on resume
[Why]
On resume we do link detection for all non-MST connectors.
MST is handled separately. However the condition for telling
if connector is on mst branch is not enough for mst hub case.
Link detection for mst branch link leads to mst topology reset.
That causes assert in dc_link_allocate_mst_payload()

[How]
Use link type as indicator for mst link.

e5fc78252c drm/amd/display: Add support for zstate during extended vblank
[why]
When we enter FREESYNC_STATE_VIDEO, we want to use the extra vblank
portion to enter zstate if possible.

[how]
When we enter freesync, a full update is triggered and the new vtotal
with extra lines is passed to dml in a stream update. The time gained
from extra vblank lines is calculated in microseconds. We allow zstate
entry if the time gained is greater than 5 ms, which is the current
policy. Furthermore, an optimized value for min_dst_y_next_start is
calculated and written to its register. When exiting freesync, another
full update is triggered and default values are restored.

[Why]
It changed since dcn30 but the hubbub31 constructor hasn't been
modified to reflect this.

[How]
Update the value in the constructor to 0x6 so we're checking the right
bits for p-state allow.

It worked before by accident, but can falsely assert 0 depending on HW
state transitions. The most frequent of which appears to be when
all pipes turn off during IGT tests.

426c89aa20 drm/amdgpu: Use drm_mode_copy()
struct drm_display_mode embeds a list head, so overwriting
the full struct with another one will corrupt the list
(if the destination mode is on a list). Use drm_mode_copy()
instead which explicitly preserves the list head of
the destination mode.

Even if we know the destination mode is not on any list
using drm_mode_copy() seems decent as it sets a good
example. Bad examples of not using it might eventually
get copied into code where preserving the list head
actually matters.

Obviously one case not covered here is when the mode
itself is embedded in a larger structure and the whole
structure is copied. But if we are careful when copying
into modes embedded in structures I think we can be a
little more reassured that bogus list heads haven't been
propagated in.

3a0625813b drm/amd/display: Retry when fail reading lane status during LT
[Why]
In dp_get_lane_status_and_lane_adjust(), we call core_link_read_dpcd()
to get lane status but we ignore the return value of the function. If
there is problem with AUX and we eventually can only get partial data
from monitor, we might misuse the data to jude the link training result.
Which could have us trapped in the dc_link_dp_perform_link_training()
since we thought that we can still give a try on another link setting.

[How]
In dp_get_lane_status_and_lane_adjust(), take return value of
core_link_read_dpcd() into account. If we fail to read all requested
data, we treat lanes status as previous one and repeat LT steps again.

22f87d9983 drm/amd/display: move FPU operations from dcn21 to dml/dcn20 folder
dml/dcn20_fpu file centralizes all DCN2x functions that require FPU access.
Therefore, this patch moves FPU-related code from dcn21 to dcn20_fpu. These
include:
- dcn21_populate_dml_pipes_from_context()
- dcn21_validate_bandwidth_fp() and related:
  - dcn21_calculate_wm(),
  - patch_bounding_box(),
  - calculate_wm_set_for_vlevel()
- renaming update_bw_bounding_box() to dcn21_update_bw_bounding_box(), move
to dcn20_fpu with related static function construct_low_pstate_lvl()

Also, make dcn21_fast_validate_bw() public in dcn21_resource as it is called
by dcn21_validate_bandwidth_fp() now in dcn20_fpu.

Reuse dcn20_fpu_adjust_dppclk() in dcn21_fast_validate_bw() as it isolates
the same FPU operation.

cf689e869c drm/amd/display: move FPU-related code from dcn20 to dml folder
Move parts of dcn20 code that uses FPU to dml folder. It aims to isolate
FPU operations as described by series:

drm/amd/display: Introduce FPU directory inside DC
https://patchwork.freedesktop.org/series/93042/

This patch moves the following functions from dcn20_resource to
dml/dcn20_fpu and calls of public functions in dcn20_resource are
wrapped by DC_FP_START/END():

- void dcn20_populate_dml_writeback_from_context
- static bool is_dtbclk_required()
- static enum dcn_zstate_support_state()
- void dcn20_calculate_dlg_params()
- static void swizzle_to_dml_params()
- int dcn20_populate_dml_pipes_from_context()
- void dcn20_calculate_wm()
- void dcn20_cap_soc_clocks()
- void dcn20_update_bounding_box()
- void dcn20_patch_bounding_box()
- bool dcn20_validate_bandwidth_fp()

This movement also affects dcn21/30/31, as dcn20_calculate_dlg_params()
is used by them. For this reason, I included dcn20_fpu headers in
dcn20_resource headers to make dcn20_calculate_dlg_params() visible to
dcn21/30/31.

Three new functions are created to isolate well-delimited FPU
operations:

- void dcn20_fpu_set_wb_arb_params(): set cli_watermark,
  pstate_watermark and time_per_pixel from wb_arb_params (struct
mcif_arb_params), since those uses FPU operations on double types:
WritebackUrgentWatermark, WritebackDRAMClockChangeWatermark, '16.0'.
- void dcn20_fpu_set_wm_ranges(): set min_fill_clk_mhz and
  max_fill_clk_mhz involves FPU calcs on dram_speed_mts (double type);
- void dcn20_fpu_adjust_dppclk(): adjust operation on RequiredDPPCLK
  that is a double.

On LNX, TO_CLK_MGR_INTERNAL() only works to get clk_mgr_internal from a
given clk_mgr. In clk_mgr_dcn316 struct, the clk_mgr_internal is already
a memeber by the alias 'base'

[How]

Use &clk_mgr->base instead.

32685b32d8 drm/amd/display: Fix double free during GPU reset on DC streams
[Why]
The issue only occurs during the GPU reset code path.

We first backup the current state prior to commiting 0 streams
internally from DM to DC. This state backup contains valid link
encoder assignments.

DC will clear the link encoder assignments as part of current state
(but not the backup, since it was a copied before the commit) and
free the extra stream reference it held.

DC requires that the link encoder assignments remain cleared/invalid
prior to commiting. Since the backup still has valid assignments we
call the interface post reset to clear them. This routine also
releases the extra reference that the link encoder interface held -
resulting in a double free (and eventually a NULL pointer dereference).

[How]
We'll have to do a full DC commit anyway after GPU reset because
the stream count previously went to 0.

We don't need to retain the assignment that we had backed up, so
just copy off of the now clean current state assignment after the
reset has occcurred with the new link_enc_cfg_copy() interface.

Fixes: 6d63fcc2a3 ("drm/amd/display: Reset link encoder assignments for GPU reset")

[why]
DP2.0 defines DP2.0 RX capability using bit maps. This means there is
a corner case the DP2.0 RX can declare UHBR20 capability but not UHBR13.5 support.
In this case we should skip UHBR13.5 selection and continue to our next option

Fangzhi Zuo
9ff28ab43a drm/amd/display: Ignore Transitional Invalid Link Rate Error Message
[Why]
When hotplug or unplug happens, each stream disabled one by one, and then
enable any alived streams. Link phy and payload table is cleared when 1st
stream is disabled. That causes the error message pops up when disable 2nd
stream. There is no active stream after link_rate is cleared.
After all streams are disabled, link will be trained again and link rate is
assigned to any alived streams.

Therefore there is no harm for the error message that represents invalid
link rate value in the atomic reset transitional time period.

[How]
Downgrade the log level from ERROR to DEBUG.

10a9accd48 drm/amd/display: Fix wrong resolution with DP/VGA adapter
[Why]
Hotplugging the VGA side of some DP/VGA adapters caused the display to
light up with the wrong (non-native) resolution.

This is caused by the adapter misbehaving by reporting the wrong number
of downstream ports when the VGA side is unplugged (reports 1 instead of
0), but only if the SINK_COUNT DPCD register is read more than once.

[How]
To work around the adapter behavior, remove the sink if link is
detected, but EDID cannot be read.

17ce8a6907 drm/amd/display: Add dsc pre-validation in atomic check
[Why]
The previous change:
"Add affected crtcs to atomic state for dsc mst unplug"
forces modeset on all added crctc regardless whether timing changed or not.
Per our implementation of dsc we need modeset only if timing changed.
Otherwise dsc can be programmed incorrectly leading to dsc engine hang.

[How]
During atomic_check pre-compute dsc params.
Only set mode_changed if timing is changed.

128f8ed590 drm/amd/display: Add affected crtcs to atomic state for dsc mst unplug
[Why]
When display topology changed on DSC hub we add all crtcs with dsc support to
atomic state.
Refer to patch:"drm/amd/display: Trigger modesets on MST DSC connectors"
However the original implementation may skip crtc if the topology change
caused by unplug.
That potentially could lead to no-lightup or corruption on DSC hub after
unplug event on one of the connectors.

[How]
Update add_affected_mst_dsc_crtcs() to use old connector state
if new connector state has no crtc (undergoes modeset due to unplug)

3b853c316c drm/amd/display: reset lane settings after each PHY repeater LT
[why]
In LTTPR non-transparent mode, we need
to reset the cached lane settings before performing
link training on the next PHY repeater. Otherwise,
the cached lane settings will be used for the next
clock recovery e.g. VS = MAX (3) which should not be
the case according to the DP specs. We expect to use
minimum lane settings on each clock recovery sequence.

[how]
Reset DPCD and HW lane settings on each repeater LT.
Set training pattern to 0 for the repeater that failed LT
at the proper place.

6d33f0e820 drm/amd/display: Fix stream->link_enc unassigned during stream removal
[Why]
Found when running igt@kms_atomic.

Userspace attempts to do a TEST_COMMIT when 0 streams which calls
dc_remove_stream_from_ctx. This in turn calls link_enc_unassign
which ends up modifying stream->link = NULL directly, causing the
global link_enc to be removed preventing further link activity
and future link validation from passing.

[How]
We take care of link_enc unassignment at the start of
link_enc_cfg_link_encs_assign so this call is no longer necessary.

Fixes global state from being modified while unlocked.

de95753cce drm/amd/display: Cap pflip irqs per max otg number
[Why]
pflip interrupt order are mapped 1 to 1 to otg id.
e.g. if irq_src=26 corresponds to otg0 then 27->otg1, 28->otg2...

Linux DM registers pflip interrupts per number of crtcs.
In fused pipe case crtc numbers can be less than otg id.

e.g. if one pipe out of 3(otg#0-2) is fused adev->mode_info.num_crtc=2
so DM only registers irq_src 26,27.
This is a bug since if pipe#2 remains unfused DM never gets
otg2 pflip interrupt (irq_src=28)
That may results in gfx failure due to pflip timeout.

[How]
Register pflip interrupts per max num of otg instead of num_crtc

33413ef964 drm/amd/display: Force link_rate as LINK_RATE_RBR2 for 2018 15" Apple Retina panels
The eDP link rate reported by the DP_MAX_LINK_RATE dpcd register (0xa) is
contradictory to the highest rate supported reported by
EDID (0xc = LINK_RATE_RBR2). The effects of this compounded with commit
'4a8ca46bae8a ("drm/amd/display: Default max bpc to 16 for eDP")' results
in no display modes being found and a dark panel.

For now, simply force the maximum supported link rate for the eDP attached
2018 15" Apple Retina panels.

Additionally, we must also check the firmware revision since the device ID
reported by the DPCD is identical to that of the more capable 16,1,
incorrectly quirking it. We also use said firmware check to quirk the
refreshed 15,1 models with Vega graphics as they use a slightly newer
firmware version.

2af104290d drm: introduce fb_modifiers_not_supported flag in mode_config
If only linear modifier is advertised, since there are many drivers that
only linear supported, the DRM core should handle this rather than
open-coding in every driver. However, there are legacy drivers such as
radeon that do not support modifiers but infer the actual layout of the
underlying buffer. Therefore, a new flag fb_modifiers_not_supported is
introduced for these legacy drivers, and allow_fb_modifiers is replaced
with this new flag.

v3:
 - change the order as follows:
   1. add fb_modifiers_not_supported flag
   2. add default modifiers
   3. remove allow_fb_modifiers flag
 - add a conditional disable in amdgpu_dm_plane_init()

v4:
 - modify kernel docs

v5:
 - modify kernel docs

configure_dp_hpo_throttled_vcp_size() was missing promotion before, but it was covered by
not calling the missing function hook in the old interface hpo_dp_link_encoder->funcs.

Recent refactor replaces with new caller link_hwss->set_throttled_vcp_size
which needs that hook, and that causes null ptr hang.

588a70177d drm/amd/display: Fix a NULL pointer dereference in amdgpu_dm_connector_add_common_modes()
In amdgpu_dm_connector_add_common_modes(), amdgpu_dm_create_common_mode()
is assigned to mode and is passed to drm_mode_probed_add() directly after
that. drm_mode_probed_add() passes &mode->head to list_add_tail(), and
there is a dereference of it in list_add_tail() without recoveries, which
could lead to NULL pointer dereference on failure of
amdgpu_dm_create_common_mode().

Fix this by adding a NULL check of mode.

4a3ad932b2 drm/amd/display: Add Cable ID support for native DP
[Why/How]
We need to handle cable capabilities for cables that support cable ID.
The cable attributes are intersected with the verified link caps to
determine appropriate max link rate. After determining cable attributes
we update the DP receiver.

b80ddeb29d drm/amd/display: Use PSR version selected during set_psr_caps
[Why]
If the DPCD caps specifies a PSR version newer than PSR_VERSION_1 then
we fallback to using PSR_VERSION_1 in amdgpu_dm_set_psr_caps.

This gets overriden with the raw DPCD value in amdgpu_dm_link_setup_psr,
which can result in DMCUB hanging if we pass in an unsupported PSR
version number.

[How]
Fix the hang by using link->psr_settings.psr_version directly during
amdgpu_dm_link_setup_psr.

09ece5ac39 drm/amd/display: Don't update drm connector when read local EDID
[Why]
Currently, when we're tentatively detecting link configuration under mst
case, we will wrongly notify a none existing stream sink to drm layer.

It's due to we'll call amdgpu_dm_update_connector_after_detect() within
dm_helpers_read_local_edid() to update connector when we're still under
tentative detection procedure.

[How]
dm_helpers_read_local_edid() was designed to do "read" only. Don't

as we add more link_hwss we are making a generic way to determine which type

Later on we may think of introduce a link policy layer. it could be a thin layer
that decide the type of link_hwss we use. So instead of passing in link and link_res
we can just pass in link_policy and swtich based on link_policy->get_link_hwss_type.

[why]
Current we have hundreds of if/else or switch statement to check
encoder type in dc_link level. The reason is because depending
on the type of encoder dc_link needs to perform similar programming
task but with different encoder interfaces. The story is to abstract
these interfaces so dc_link can just perform the programming task
without knowing the detail of which encoder it's dealing with.

c282d9512c drm/amd/display: factor out dp detection link training and mst top detection
[why]
dc_link_detect_helper has multiple purpose:
1. Detect link and local sink.
2. Verify link capability by performing detection link training.
3. Start mst topology discovery and if succeeded fails the current interface.

This is difficult to maintain as item 2 has become more destructive to current
dc state. The change is to decouple these sequences to its own functions.
Eventually only item 2 is a destructive method and we will redesign this
sequence with a more unified policy across different encoder types.

at the same time, system will hang.

[How]
Revert MPC split policy back to "MPC_SPLIT_AVOID". Since we have
ODM combine enabled on DCN301, pipe split is not necessary here.

552b7cb0ee drm/amd/display: move calcs folder into DML
The calcs folder has FPU code on it, which should be isolated inside the
DML folder as per https://patchwork.freedesktop.org/series/93042/.

This commit aims single-handedly to correct the location of such FPU
code and does not refactor any functions.

Changes since v2:
- Corrected problems to compile when DCN was disabled.

047db281c0 drm/amd/display: Add signal type check when verify stream backends same
[Why]
For allow eDP hot-plug feature, the stream signal may change to VIRTUAL
when plug-out and back to eDP when plug-in. OS will still setPathMode
with same timing for each plugging, but eDP gets no stream update as we
don't check signal type changing back as keeping it VIRTUAL. It's also
unsafe for future cases that stream signal is switched with same timing.

[How]
Check stream signal type change include previous HDMI signal case.

79d6b9351f drm/amd/display: Don't reinitialize DMCUB on s0ix resume
[Why]
PSP will suspend and resume DMCUB. Driver should just wait for DMCUB to
finish the auto load before continuining instead of placing it into
reset, wiping its firmware state and reinitializing.

If we don't let DMCUB fully finish initializing for S0ix then some state
will be lost and screen corruption can occur due to incorrect address
translation.

[How]
Use dmub_srv callbacks to determine in DMCUB is running and wait for
auto-load to complete before continuining.

In S0ix DMCUB will be running and DAL fw so initialize will skip.

In S3 DMCUB will not be running and we will do a full hardware init.

580013b2ce drm/amd/display: unhard code link to phy idx mapping in dc link and clean up
[why]
1. Current code hard codes link to PHY mapping in dc link level per asic
per revision.
This is not scalable. In long term the mapping will be obatined from
DMUB and store in dc resource.

2. Depending on DCN revision and endpoint type, the definition of
dio_output_idx dio_output_type and phy_idx are not  consistent. We need
to unify the meaning of these hardware indices across different system
configuration.

[how]
1. Temporarly move the hardcoded mapping to dc_resource level, which
should have full awareness of asic specific configuration and add a TODO
comment to move the mapping to DMUB.

2. populate dio_output_idx/phy_idx for all configuration, define
usb4_enabled bit instead of dio_output_type as an external enum.

771ced73fc drm/amd/display: Fix underflow for fused display pipes case
[Why]
Depend on res_pool->res_cap->num_timing_generator to query timing
gernerator information, it would case underflow at the fused display
pipes case.
Due to the res_pool->res_cap->num_timing_generator records default
timing generator resource built in driver, not the current chip.

[How]
Some ASICs would be fused display pipes less than the default setting.
In dcnxx_resource_construct function, driver would obatin real timing
generator count and store it into res_pool->timing_generator_count.

ef30f441f6 drm/amd/display: define link res and make it accessible to all link interfaces
[why]
There will be a series of re-arch changes in Link Resource Management.
They are more and more muxable link resource objects and the resource is
insufficient for a one to one allocation to all links created.
Therefore a link resource sharing logic is required to determine which
link should use certain link resource.

This commit is the first one in this series that starts by defining a
link resource struct, this struct will be available to all interfaces
that need to perform link programming sequence.

In later commits, we will granduately decouple link resource objects out
of dc link. So instead of access a link resource from dc link. Current
link's resource can be accessible through pipe_ctx->link_res during
commit, or by calling  dc_link_get_cur_link_res function with current
link passed in after commit.

SMU will try to enter Z9 too early in these cases (before PSR is

0215466a85 drm/amd/display: Set exit_optimized_pwr_state for DCN31
[Why]
SMU now respects the PHY refclk disable request from driver.

This causes a hang during hotplug when PHY refclk was disabled
because it's not being re-enabled and the transmitter control
starts on dc_link_detect.

[How]
We normally would re-enable the clk with exit_optimized_pwr_state
but this is only set on DCN21 and DCN301. Set it for dcn31 as well.

This fixes DMCUB timeouts in the PHY.

  2. Get rid of unused functions in order to remove 'defined but not

c1e003d3ff drm/amd/display: Reduce stack size for dml31_ModeSupportAndSystemConfigurationFull
Move code using the Pipe struct to a new helper function.

Works around[0] this warning (resulting in failure to build a RHEL debug
kernel with Werror enabled):

../drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn31/display_mode_vba_31.c: In function ‘dml31_ModeSupportAndSystemConfigurationFull’:

The culprit seems to be the Pipe struct, so pull the relevant block out
into its own sub-function. (This is porting
commit a62427ef9b ("drm/amd/display: Reduce stack size for dml21_ModeSupportAndSystemConfigurationFull")
from dml31 to dml21)

[0] AFAICT this doesn't actually reduce the total amount of stack which
can be used, just moves some of it from
dml31_ModeSupportAndSystemConfigurationFull to the new helper function,
so the former happens to no longer exceed the limit for a single
function.

Since it does not pass through the power layer, the layer

PSR state in FW.
Theoretically PSR can be enabled during hw programming

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

2da34b7bb5 drm/amd/display: add connector type check for CRC source set
[Why]
IGT bypass test will set crc source as DPRX,and display DM didn`t check
connection type, it run the test on the HDMI connector ,then the kernel
will be crashed because aux->transfer is set null for HDMI connection.
This patch will skip the invalid connection test and fix kernel crash issue.

[How]
Check the connector type while setting the pipe crc source as DPRX or
auto,if the type is not DP or eDP, the crtc crc source will not be set
and report error code to IGT test,IGT will show the this subtest as no
valid crtc/connector combinations found.

a896f870f8 drm/amd/display: Fix for otg synchronization logic
[Why]
During otg sync trigger, plane states are used to decide whether the otg
is already synchronized or not. There are scenarions when otgs are
disabled without plane state getting disabled and in such case the otg is
excluded from synchronization.

[How]
Introduced pipe_idx_syncd in pipe_ctx that tracks each otgs master pipe.
When a otg is disabled/enabled, pipe_idx_syncd is reset to itself.
On sync trigger, pipe_idx_syncd is checked to decide whether a otg is
already synchronized and the otg is further included or excluded from
synchronization.

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.

2276ee6d1b 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.

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.

524a0ba6fa drm/amd/display: Fix DPIA outbox timeout after GPU reset
[Why]
The HW interrupt gets disabled after GPU reset so we don't receive

Re-enable the interrupt after GPU reset like we do for the other
DC interrupts.

4cbe435dd6 drm/amd/display: retain/release stream pointer in link enc table
[why]
At every reference to stream pointer, we need to increment/decrement the
kref_count.  Not doing so will result in invalid stream pointer still
alive after hibernate cycle.

[how]
Call stream retain/release whenever the link encoder assignment is set
to true/false since it indicates if we want to reference the stream
pointer or not.

e43098f6ab drm/amd/display: fix stale info in link encoder assignment
[Why]
The link encoder assignment leaves the old stream data when it was
unassigned. When the clear encoder assignment is called, it based on the
old stale data to access the de-allocated stream.

[How]
There should be no need to explicitly clean up the link encoder
assignment if the unassign loop does the work properly, the loop should
base on the current state to clean up the assignment.

Also, the unassignment should better clean up the values in the
assignement slots as well.

1328e395fd drm/amd/display: Fix detection of aligned DMUB firmware meta info
[Why]
A built firmware binary may be aligned to 16-bytes with padding at the
end as necessary. In the case that padding was applied the meta info
will not be detected correctly and we won't be able to allocate the
appropriate firmware and tracebuffer sizes.

[How]
To maintain compatibility with already released firmware where this
occurs we need to try every meta offset from 0..15 inclusive.

Extract out the meta info checker into a helper function that's called
for each of these offsets and exit early when we've found it.

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.

91adec9e07 drm/amd/display: Look at firmware version to determine using dmub on dcn21
commit 652de07add ("drm/amd/display: Fully switch to dmub for all dcn21
asics") switched over to using dmub on Renoir to fix Gitlab 1735, but this
implied a new dependency on newer firmware which might not be met on older
kernel versions.

Since sw_init runs before hw_init, there is an opportunity to determine
whether or not the firmware version is new to adjust the behavior.

139a33112f drm/amd/display: MST support for DPIA
[Why]
- DPIA MST slot registers are not programmed during payload
allocation and hence MST does not work with DPIA.
- HPD RX interrupts are not handled for DPIA.

[How]
- Added inbox command to program the MST slots whenever
  payload allocation happens for DPIA links.
- Added support for handling HPD RX interrupts

1e5588d140 drm/amd/display: Fallback to clocks which meet requested voltage on DCN31
[WHY]
On certain configs, SMU clock table voltages don't match which cause parser
to behave incorrectly by leaving dcfclk and socclk table entries unpopulated.

[HOW]
Currently the function that finds the corresponding clock for a given voltage
only checks for exact voltage level matches. In the case that no match gets
found, parser now falls back to searching for the max clock which meets the
requested voltage (i.e. its corresponding voltage is below requested).

Why:
For audio packet type 0x02, there are 2 Layouts:
   Layout = 0 for 2 channels
and Layout = 1 for > 2 channels.
Layout will affect bandwidth check.

Currently, for HDMI FRL, Layout field isn't set and has a default value
of 0, so theoretically only 2-channel audio for audio packet type 0x02
is supported now.

How:
1. Set Layout properly according to maximum audio channel numbers for
audios with audio packet type 0x02.
2. 8ch LPCM audio is not supported for timing modes with v_active <= 576.

bc39a69a2a drm/amd/display: dcn20_resource_construct reduce scope of FPU enabled
Limit when FPU is enabled to only functions that does FPU operations for
dcn20_resource_construct, which gets called during driver

Enabling FPU operation disables preemption.  Sleeping functions(mutex

when preemption is disabled.

54149d13f3 drm/amd/display: Fallback to clocks which meet requested voltage on DCN31
[WHY]
On certain configs, SMU clock table voltages don't match which cause parser
to behave incorrectly by leaving dcfclk and socclk table entries unpopulated.

[HOW]
Currently the function that finds the corresponding clock for a given voltage
only checks for exact voltage level matches. In the case that no match gets
found, parser now falls back to searching for the max clock which meets the
requested voltage (i.e. its corresponding voltage is below requested).

In 128b/132b encoding format, metadata is transmitted separately

v2:
* Move total/start slots to mst_state, and copy it to mst_mgr in

v3:
* Only keep the slot info on the mst_state
* add a start_slot parameter to the payload function, to facilitate non

  we are moving out the non atomic driver helpers)

41ad36623f amd/display: remove ChromeOS workaround
This reverts commits ddab8bd788 ("drm/amd/display: Fix two cursor duplication
when using overlay") and e7d9560aea ("Revert "drm/amd/display: Fix overlay
validation by considering cursors"").

tl;dr ChromeOS uses the atomic interface for everything except the cursor. This
is incorrect and forces amdgpu to disable some hardware features. Let's revert
the ChromeOS-specific workaround in mainline and allow the Chrome team to keep
it internally in their own tree.

See [1] for more details. This patch is an alternative to [2], which added
ChromeOS detection.

[Why]
Immediate flip can be enabled dynamically and has higher BW requirements
when validating which voltage mode to use.

If we validate when it's not set then potentially DCFCLK will be too low
and we will underflow.

[How]
DM always requires support so always require it as part of DML input
parameters.

This can't be enabled unconditionally on older ASIC because it blocks
some expected modes so only target DCN3.1 for now.

5595e962bd drm/amd/display: Require immediate flip support for DCN3.1 planes
[Why]
Immediate flip can be enabled dynamically and has higher BW requirements
when validating which voltage mode to use.

If we validate when it's not set then potentially DCFCLK will be too low
and we will underflow.

[How]
DM always requires support so always require it as part of DML input
parameters.

This can't be enabled unconditionally on older ASIC because it blocks
some expected modes so only target DCN3.1 for now.

d5ce4313cc drm/amd/display: Do not skip link training on DP quick hot plug
[Why]
When rapidly plugging and unplugging a DP sink, detection link
training can be mistakenly skipped.

This is due to the hotplug processing occurring before the
encoder assignment logic has had a chance to process the removal
of a stream. The encoder that would be used for detection link
training is then erroneously reported as already in use and
detection link training is skipped.

[How]
During hot plug processing, only determine a link encoder to be
unavailable for a particular link if it has been assigned to a
different link.

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.

Iterate over the CRTC planes and check their scaling match

[HOW]

   dc_link_construct() implementation is split for legacy DDC and DPIAs.
   As usb4 has no ddc, ddc->ddc_pin will be set to NULL for its dc link
   and this parameter will be used to identify the dc links as DPIA. The
   dc link for DPIA is further to be enhanced with implementation for link
   encoder and link initialization.
2) usb4_dpia_count in struct resource_pool will be initialized to 4 in

8da5cbafb2 drm/amd/display: Fix concurrent dynamic encoder assignment.
[Why]
Trying to enable multiple displays simultaneously exposed shortcomings
with the algorithm for dynamic link encoder assignment.

The main problems were:
- Assuming stream order remained constant across states would
sometimes lead to invalid DIG encoder assignment.
- Incorrect logic for deciding whether or not a DIG could support a
stream would also sometimes lead to invalid DIG encoder assignment.
- Changes in encoder assignment were wholesale while updating of the
pipe backend is incremental. This would lead to the hardware state
not matching the software state even with valid encoder assignments.

[How]

The following changes fix the identified problems.
- Use stream pointer rather than stream index to track streams across
states.
- Fix DIG compatibility check by examining the link signal type
rather than the stream signal type.
- Modify assignment algorithm to make incremental updates so software
and hardware states remain coherent.

Additionally:
- Add assertions and an encoder assignment validation
function link_enc_cfg_validate() to detect potential problems with
encoder assignment closer to their root cause.
- Reduce the frequency with which the assignment algorithm is
executed. It should not be necessary for fast state validation.

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

6131538b49 drm/amd/display: Only define DP 2.0 symbols if not already defined
[Why]
For some reason we're defining DP 2.0 definitions inside our
driver. Now that patches to introduce relevant definitions
are slated to be merged into drm-next this is causing conflicts.

In file included from drivers/gpu/drm/amd/amdgpu/amdgpu_bo_list.c:33:
In file included from ./drivers/gpu/drm/amd/amdgpu/../amdgpu/amdgpu.h:70:

./drivers/gpu/drm/amd/amdgpu/../display/dc/dc_dp_types.h:881:9: note: previous definition is here
        ^
1 error generated.

[How]
Guard all display driver defines with #ifndef for now. Once we pull
in the new definitions into amd-staging-drm-next we will follow
up and drop definitions from our driver and provide follow-up
header updates for any addition DP 2.0 definitions required
by our driver.

We also ensure drm_dp_helper.h is included before dc_dp_types.h.

v3: Ensure drm_dp_helper.h is included before dc_dp_types.h

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.

0d4b4253ad drm/amd/display: Fix dynamic encoder reassignment
[Why]
Incorrect encoder assignments were being used while applying a new state
to hardware.

(1) When committing a new state to hardware requires resetting the
back-end, the encoder assignments of the current or old state should be
used when disabling the back-end; and the encoder assignments for the
next or new state should be used when re-enabling the back-end.

(2) Link training on hot plug could take over an encoder already in use
by another stream without first disabling it.

[How]

(1) Introduce a resource context 'link_enc_cfg_context' which includes:
- a mode to indicate when transitioning from current to next state.
- transient encoder assignments to use during this state transition.

Update the encoder configuration interface to respond to queries about
encoder assignment based on the mode of operation.

(2) Check if an encoder is already in use before attempting to perform
link training on hot plug.

b3492ed160 drm/amd/display: Fix concurrent dynamic encoder assignment
[Why]
Trying to enable multiple displays simultaneously exposed shortcomings
with the algorithm for dynamic link encoder assignment.

The main problems were:
- Assuming stream order remained constant across states would sometimes
lead to invalid DIG encoder assignment.
- Incorrect logic for deciding whether or not a DIG could support a
stream would also sometimes lead to invalid DIG encoder assignment.
- Changes in encoder assignment were wholesale while updating of the
pipe backend is incremental. This would lead to the hardware state not
matching the software state even with valid encoder assignments.

[How]

The following changes fix the identified problems.
- Use stream pointer rather than stream index to track streams across
states.
- Fix DIG compatibility check by examining the link signal type rather
than the stream signal type.
- Modify assignment algorithm to make incremental updates so software
and hardware states remain coherent.

Additionally:
- Add assertions and an encoder assignment validation function
link_enc_cfg_validate() to detect potential problems with encoder
assignment closer to their root cause.
- Reduce the frequency with which the assignment algorithm is executed.
It should not be necessary for fast state validation.

1bd3bc745e drm/amd/display: Extend w/a for hard hang on HPD to dcn20
[Why]
HPD disable and enable sequences are not mutually exclusive on Linux.
For HPDs that spans under 1s (i.e. HPD low = 1s), part of the disable
sequence (specifically, a request to SMU to lower refclk) could come
right before the call to PHY enablement, causing DMUB to access an
irresponsive PHY and thus a hard hang on the system.

[How]
Disable 48mhz refclk off when there is any HPD status in connected state
for dcn20.

dcn_bw_calc_rq_dlg_ttu uses a stack frame great than 1024. To solve this
we could allocate the rq_param, dlg_sys_param, and input structs
dynamically. Since this function is inside a kernel_fpu_begin()/end()
call we want to avoid memory allocation. Instead it's much
safer to pre-allocate these on the pipe_ctx.

}

bpp / 16 trunc digits after decimal point. This will cause calculation
delta. drm_dp_calc_pbn_mode does not have other informations,

9987fbb368 drm/amd/display: Get backlight from PWM if DMCU is not initialized
On Carrizo/Stoney systems we set backlight through panel_cntl, i.e.
directly via the PWM registers, if DMCU is not initialized. We
always read it back through ABM registers which leads to a
mismatch and forces atomic_commit to program the backlight
each time.

Instead make sure we use the same logic for backlight readback,
i.e. read it from panel_cntl if DMCU is not initialized.

We also need to remove some extraneous and incorrect calculations
at the end of dce_get_16_bit_backlight_from_pwm.

7bbee36d71 amd/display: downgrade validation failure log level
In amdgpu_dm_atomic_check, dc_validate_global_state is called. On
failure this logs a warning to the kernel journal. However warnings
shouldn't be used for atomic test-only commit failures: user-space
might be perfoming a lot of atomic test-only commits to find the
best hardware configuration.

Downgrade the log to a regular DRM atomic message. While at it, use
the new device-aware logging infrastructure.

This fixes error messages in the kernel when running gamescope [1].

HPD disable and enable sequences are not mutually exclusive
on Linux. For HPDs that spans under 1s (i.e. HPD low = 1s),
part of the disable sequence (specifically, a request to SMU

enablement, causing DMUB to access an irresponsive PHY

9e0d55ae54 drm/amd/display: Get backlight from PWM if DMCU is not initialized
On Carrizo/Stoney systems we set backlight through panel_cntl, i.e.
directly via the PWM registers, if DMCU is not initialized. We
always read it back through ABM registers which leads to a
mismatch and forces atomic_commit to program the backlight
each time.

Instead make sure we use the same logic for backlight readback,
i.e. read it from panel_cntl if DMCU is not initialized.

We also need to remove some extraneous and incorrect calculations
at the end of dce_get_16_bit_backlight_from_pwm.

64d283cb37 drm/amd/display: Fix dynamic link encoder access.
[Why]
Assuming DIG link encoders are statically mapped to links can cause
system instability due to null pointer accesses.

[How]
- Add checks for non-null link encoder pointers before trying to access
them.
- When a hardware platform uses dynamic DIG assignment (i.e. resource
function 'link_encs_assign' defined) and a link supports flexible
mapping to DIGs, use the link_enc_cfg API to access the DIG assigned to
a link or stream.

035f54969b drm/amd/display: Add flag to detect dpms force off during HPD
[Why] When a connector is unplugged, dpms is forced off so that some
connector allocations are cleared off. This is done outside the commit
sequence from the userspace. This causes HUBP blank. Due to the blank
hubp, a non blocking commit which queues flip will encounter a timeout
waiting for the flip_done because prior to writing the surface flip
address, hubp was in blank.

[How] Add a marker to DM's crtc state and use this field to indicate
whether dpms was forced off during an HPD. Check for this marker before
queuing the flip.

6077911b49 drm/amd/display: unblock abm when odm is enabled only on configs that support it
[Why]
When ODM is enabled, ABM is blocked on dcn31 but unblocked on dcn30.

Since the dcn31 firmware is now able to handle ABM interop with ODM, it
is no longer necessary to block ABM when ODM is enabled.

Since the dcn30 firmware does not handle ABM interop with ODM, leaving
that combination unblocked can lead to one side of the screen appearing
brighter than the other.

[How]
When ODM is enabled, unblock abm on dcn31 and block it on dcn30

8e794421bc drm/amd/display: Fork thread to offload work of hpd_rx_irq
[Why]
Currently, we will try to get dm.dc_lock in handle_hpd_rx_irq() when
link lost happened, which is risky and could cause deadlock.
e.g. If we are under procedure to enable MST streams and then monitor
happens to toggle short hpd to notify link lost, then
handle_hpd_rx_irq() will get blocked due to stream enabling flow has
dc_lock. However, under MST, enabling streams involves communication
with remote sinks which need to use handle_hpd_rx_irq() to handle
sideband messages. Thus, we have deadlock here.

[How]
Target is to have handle_hpd_rx_irq() finished as soon as possilble.
Hence we can react to interrupt quickly. Besides, we should avoid to
grabe dm.dc_lock within handle_hpd_rx_irq() to avoid deadlock situation.

Firstly, revert patches which introduced to use dm.dc_lock in
handle_hpd_rx_irq():

* commit ("drm/amd/display: NULL pointer error during ")

* commit ("drm/amd/display: Only one display lights up while using MST")

* commit ("drm/amd/display: take dc_lock in short pulse handler only")

Instead, create work to handle irq events which needs dm.dc_lock.
Besides:

* Create struct hpd_rx_irq_offload_work_queue for each link to handle
  its short hpd events

* Avoid to handle link lost/ automated test if the link is disconnected

* Defer dc_lock needed works in dc_link_handle_hpd_rx_irq(). This
  function should just handle simple stuff for us (e.g. DPCD R/W).
  However, deferred works should still be handled by the order that
  dc_link_handle_hpd_rx_irq() used to be.

* Change function name dm_handle_hpd_rx_irq() to
  dm_handle_mst_sideband_msg() to be more specific

Due to some code flow constraints, we need to defer dc_lock needed works

* Change allow_hpd_rx_irq() from static to public
* Change handle_automated_test() from static to public
* Extract link lost handling flow out from dc_link_handle_hpd_rx_irq()
  and put those into a new function dc_link_dp_handle_link_loss()
* Add one option parameter to decide whether defer works within
  dc_link_handle_hpd_rx_irq()

a906331c45 amd/display: downgrade validation failure log level
In amdgpu_dm_atomic_check, dc_validate_global_state is called. On
failure this logs a warning to the kernel journal. However warnings
shouldn't be used for atomic test-only commit failures: user-space
might be perfoming a lot of atomic test-only commits to find the
best hardware configuration.

Downgrade the log to a regular DRM atomic message. While at it, use
the new device-aware logging infrastructure.

This fixes error messages in the kernel when running gamescope [1].

Merge tag 'kbuild-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild

Pull Kbuild updates from Masahiro Yamada:

 - Add -s option (strict mode) to merge_config.sh to make it fail when
   any symbol is redefined.

 - Show a warning if a different compiler is used for building external
   modules.

 - Infer --target from ARCH for CC=clang to let you cross-compile the
   kernel without CROSS_COMPILE.

 - Make the integrated assembler default (LLVM_IAS=1) for CC=clang.

 - Add <linux/stdarg.h> to the kernel source instead of borrowing
   <stdarg.h> from the compiler.

 - Add Nick Desaulniers as a Kbuild reviewer.

 - Drop stale cc-option tests.

 - Fix the combination of CONFIG_TRIM_UNUSED_KSYMS and CONFIG_LTO_CLANG
   to handle symbols in inline assembly.

 - Show a warning if 'FORCE' is missing for if_changed rules.

 - Various cleanups

9b2fdc3321 drm/amd/display: Add emulated sink support for updating FS
[Why]
When forced modes are used during certain IGT tests,
without a real connector, dc_sink would be null when
standard modes are added by the driver. Calling the
function to update freesync capabilities at this
point will result in an error being printed

[How]
Use emulated sink when available. If both the normal
and emulated sink are not available, set all freesync
parameters to 0.

b5ce6fe812 drm/amd/display: add missing ABM register offsets
[Why]
Some ABM registers don't exist on DCN 3.01, so are
missing from its register offset list. However,
this list was copied to later versions of DCN that
do have these registers. As a result, they're
inaccessible from the driver on those DCN versions
even though they exist.

[How]
Add the missing ABM register offsets to DCN 3.02+
