drm/atomic: Pass the full state to planes async atomic check and update
The current atomic helpers have either their object state being passed as
an argument or the full atomic state.

The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.

Let's start convert all the remaining helpers to provide a consistent
interface, starting with the planes atomic_async_check and
atomic_async_update.

The conversion was done using the coccinelle script below, built tested on
all the drivers.

688f97ed3f drm/amd/display: Add vupdate_no_lock interrupts for DCN2.1
When run igt@kms_vrr in a device that uses DCN2.1 architecture, we
noticed multiple failures. Furthermore, when we tested a VRR demo, we
noticed a system hang where the mouse pointer still works, but the
entire system freezes; in this case, we don't see any dmesg warning or
failure messages kernel. This happens due to a lack of vupdate_no_lock
interrupt, making the userspace wait eternally to get the event back.
For fixing this issue, we need to add the vupdate_no_lock interrupt in
the interrupt list.

349a19b2f1 drm/amd/display: Check for DSC support instead of ASIC revision
[why]
This check for ASIC revision is no longer useful and causes
lightup issues after a topology change in MST DSC scenario.
In this case, DSC configs should be recalculated for the new
topology. This check prevented that from happening on certain
ASICs that do, in fact, support DSC.

[how]
Change the ASIC revision to instead check if DSC is supported.

737b2b536a drm/amd/display: Fix MPC OGAM power on/off sequence
[Why]
Color corruption can occur on bootup into a login
manager that applies a non-linear gamma LUT because
the LUT may not actually be powered on before writing.

It's cleared on the next full pipe reprogramming as
we switch to LUTB from LUTA and the pipe accessing
the LUT has taken it out of light sleep mode.

[How]
The MPCC_OGAM_MEM_PWR_FORCE register does not force
the current power mode when set to 0. It only forces
when set light sleep, deep sleep or shutdown.

The register to actually force power on and ignore
sleep modes is MPCC_OGAM_MEM_PWR_DIS - a value of 0
will enable power requests and a value of 1 will
disable them.

When PWR_FORCE!=0 is combined with PWR_DIS=0 then
MPCC OGAM memory is forced into the state specified
by the force bits.

If PWR_FORCE is 0 then it respects the mode specified
by MPCC_OGAM_MEM_LOW_PWR_MODE if the RAM LUT is not
in use.

We set that bit to shutdown on low power, but otherwise
it inherits from bootup defaults.

So for the fix:

1. Update the sequence to "force" power on when needed

We can use MPCC_OGAM_MEM_PWR_DIS for this to turn on the
memory even when the block is in bypass and pending to be
enabled for the next frame.

We need this for both low power enabled or disabled.

If we don't set this then we can run into issues when we
first program the LUT from bootup.

2. Don't apply FORCE_SEL

Once we enable power requests with DIS=0 we run into the
issue of the RAM being forced into light sleep and being
unusable for display output. Leave this 0 like we used to
for DCN20.

3. Rely on MPCC OGAM init to determine light sleep/deep sleep

MPC low power debug mode isn't enabled on any ASIC currently
but we'll respect the setting determined during init if it
is.

Lightly tested as working with IGT tests and desktop color
adjustment.

4. Change the MPC resource default for DCN30

It was interleaving the dcn20 and dcn30 versions before
depending on the sequence.

5. REG_WAIT for it to be on whenever we're powering up the
memory

Otherwise we can write register values too early and we'll
get corruption.

dc_sink_release before a new dc_sink is assigned back to
aconnector->dc_sink.

[how]
Decrement the dc_sink refcount before reassigning it to a new dc_sink.

fa2a3786c4 drm/amd/display: reuse current context instead of recreating one
[Why]
Currently we discard the current context and recreate it. The current
context is what is applied to the HW so we should be re-using this
rather than creating a new context.

Recreating the context can lead to mismatch between new context and the
current context

For example: gsl groups get changed when we create a new context this
can cause issues in a multi display config (with flip immediate) because
we don't align the existing gsl groups in the new and current context.
If we reuse the current context the gsl group assignment stays the same.

[How]
Instead of discarding the current context, we instead just copy the
current state and add/remove planes and streams.

efa18405ba drm/amd/display: Fix HDMI deep color output for DCE 6-11.
This fixes corrupted display output in HDMI deep color
10/12 bpc mode at least as observed on AMD Mullins, DCE-8.3.

It will hopefully also provide fixes for other DCE's up to
DCE-11, assuming those will need similar fixes, but i could
not test that for HDMI due to lack of suitable hw, so viewer
discretion is advised.

dce110_stream_encoder_hdmi_set_stream_attribute() is used for
HDMI setup on all DCE's and is missing color_depth assignment.

dce110_program_pix_clk() is used for pixel clock setup on HDMI
for DCE 6-11, and is missing color_depth assignment.

Additionally some of the underlying Atombios specific encoder
and pixelclock setup functions are missing code which is in
the classic amdgpu kms modesetting path and the in the radeon
kms driver for DCE6/DCE8.

encoder_control_digx_v3() - Was missing setup code wrt. amdgpu
and radeon kms classic drivers. Added here, but untested due to
lack of suitable test hw.

encoder_control_digx_v4() - Added missing setup code.
Successfully tested on AMD mullins / DCE-8.3 with HDMI deep color
output at 10 bpc and 12 bpc.

Note that encoder_control_digx_v5() has proper setup code in place
and is used, e.g., by DCE-11.2, but this code wasn't used for deep
color setup due to the missing cntl.color_depth setup in the calling
function for HDMI.

set_pixel_clock_v5() - Missing setup code wrt. classic amdgpu/radeon
kms. Added here, but untested due to lack of hw.

set_pixel_clock_v6() - Missing setup code added. Successfully tested
on AMD mullins DCE-8.3. This fixes corrupted display output at HDMI
deep color output with 10 bpc or 12 bpc.

1916866dfa drm/amd/display: Fix 10/12 bpc setup in DCE output bit depth reduction.
In set_clamp(), the comments and definitions for the COLOR_DEPTH_101010
and COLOR_DEPTH_121212 cases directly contradict the code comment which
explains how this should work, whereas the COLOR_DEPTH_888 case
is consistent with the code comments. Comment says the bitmask should
be chosen to align to the top-most 10 or 12 MSB's on a 14 bit bus, but
the implementation contradicts that: 10 bit case sets a mask for 12 bpc
clamping, whereas 12 bit case sets a mask for 14 bpc clamping.

Note that during my limited testing on DCE-8.3 (HDMI deep color)
and DCE-11.2 (DP deep color), this didn't have any obvious ill
effects, neither did fixing it change anything obvious for the
better, so this fix may be inconsequential on DCE, and just
reduce the confusion of innocent bystanders when reading the code
and trying to investigate problems with 10 bpc+ output.

5383007716 drm/amd/display: Update dram_clock_change_latency for DCN2.1
[WHY]
dram clock change latencies get updated using ddr4 latency table, but
that update does not happen before validation. This value
should not be the default and should be number received from
df for better mode support.
This may cause a PState hang on high refresh panels with short vblanks
such as on 1080p 360hz or 300hz panels.

[HOW]
Update latency from 23.84 to 11.72.

[Why]
When no displays are currently enabled, display driver should not
disallow PSTATE switching.

d740a39c3d drm/amd/display: Fix reset sequence with driver direct DMCUB fw load
[Why]
DMCUB encounters a page fault/double exception with driver direct load
because DMCUB is not held in soft reset after releasing secure reset.

The clean shutdown sequence via GPINT is also not executed in this
sequence which leaves hardware behavior in an indeterminate state.

[How]
Move reset earlier in the sequence.

1c26a1bf3b drm/amd/display: Fix to be able to stop crc calculation
[Why]
Find out when we try to disable CRC calculation, crc generation is still
enabled. Main reason is that dc_stream_configure_crc() will never get
called when the source is AMDGPU_DM_PIPE_CRC_SOURCE_NONE.

[How]
Add checking condition that when source is
AMDGPU_DM_PIPE_CRC_SOURCE_NONE, we should also call
dc_stream_configure_crc() to disable crc calculation.

9e01f800e5 drm/amd/display/dc/dce112/Makefile: Ignore -Woverride-init warning
This file uses a complex abstracted set of hierarchical macros to
setup its applicable register lists within constant structures.
However in the case of TMDS_CNTL we wish to mark it as not applicable
for this use-case.

One method would be to de-const all of the definitions and users, then
manually zero out TMDS_CNTL from the list.  Another would be to create
a new set of hierarchical macros to omit TMDS_CNTL entirely.  Both
would entail a great deal of unnecessary changes and maintenance
burden.

Fixes the following W=1 kernel build warning(s):

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

commit a861736dae ("drm/amd/display: Fixed Intermittent blue screen on OLED panel")

causes power regression for many users. It seems that this change causes
the MCLK to get forced high; this creates a regression for many users
since their devices were not able to drop to a low state after this
change. For this reason, this reverts commit
a861736dae.

9c63852f4a drm/amd/display: disable dcn10 pipe split by default
[Why]
The initial purpose of dcn10 pipe split is to support some high
bandwidth mode which requires dispclk greater than max dispclk. By
initial bring up power measurement data, it showed power consumption is
less with pipe split for dcn block. This could be reason for enable pipe
split by default. By battery life measurement of some Chromebooks,
result shows battery life is longer with pipe split disabled.

[How]
Disable pipe split by default. Pipe split could be still enabled when
required dispclk is greater than max dispclk.

985faf2c4e drm/amd/display: New sequence for HUBP blank
[WHY]
DCN30 has a bug where blanking HUBP blocks pstate allow unless
HUBP_DISABLE is toggled afterwards.

[HOW]
Create a HW sequence for blanking HUBP.
1. Wait for enter VBLANK
2. Set HUBP_BLANK
3. Make sure HUBP_IN_BLANK = 1
4. Toggle HUBP_DISABLE on and off to perform soft reset

All existing calls to hubp->funcs->set_blank should be replaced with
this new sequence.
In wait_for_mpcc_disconnect, only blank the pipe being disconnected, and
leave all other pipes unmodified.

cf3a262759 drm/amd/display: implement T12 compliance
[why]
When OS reboots, and panel is turned off, T12 may not be maintained.
T12 is defined as the interval between VDDC off (occurs at shutdown) and
the next VDDC on (occurs when eDP is POST-ed)

[how]
DC already tracks panel power off time.  Add a DC interface which DM can
call during shutdown.  Ideally this should be as late as possible during
the shutdown sequence so the extra delay is minimal.

29d5ac563c drm/amd/display: doesn't reprogram AMD OUI
[Why]
1. the corrected timing to write DPCD 300h AMD signature is before
link training.
2. and VBIOS will writes correctted AMD signature by after AGESA 1.0.0,
so driver doesn't need to write DPCD 300h again to switch config.
3. there are some OLED panel will clean backlight level to 0 once
receive DPCD 300h, so we will see flicker issue at that time.

[How]
read DPCD 300h signature before write it to avoid reprogram again, if
AMD signature was writed corrected by VBIOS, driver will not reprogram
it again.

ae2175641a drm/amd/display: removed unnecessary check when dpp clock increasing
[Why]
When switching single pipe to split pipe, the bandwidth check is just
for first pipe.  The 2nd pipe with abnormal(or zero) dpp clock when pipe
ready and unlock leads the garbage on display.

[How]
Removed external increasing dpp clock check, the internal function
already loops all of pipes to check whether update dpp clock.

fd1c85d3ac drm/amd/display: Unblank hubp based on plane visibility
[WHY]
DCN10 uses plane visibility to determine when to unblank HUBP; there is
no reason DCN20+ should not do the same.

[HOW]
In addition to changing the check in HWSEQ, we must change
is_pipe_tree_visible so that it checks ODM pipe topologies as well as
MPC. Since we're now checking both ODM and MPC topologies, the helper
function names have been changed to reference "parent" and "child"
instead of "top" and "bottom".

1dbb6c8fa6 drm/amd/display: tweak the kerneldoc for active_vblank_irq_count
Commit 71338cb4a7 ("drm/amd/display: enable idle optimizations for linux
(MALL stutter)") adds active_vblank_irq_count to amdgpu_display_manager
in ./drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.h.

The kerneldoc is incorrectly formatted, and make htmldocs warns:

  ./drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.h:
    340: warning: Incorrect use of kernel-doc format:          * @active_vblank_irq_count
    379: warning: Function parameter or member 'active_vblank_irq_count' not described in 'amdgpu_display_manager'

Tweak the kerneldoc for active_vblank_irq_count.

This leads to blank screens on some boards after replugging a
display.  Revert until we understand the root cause and can
fix both the leak and the blank screen after replug.

88d5cb2517 drm/amdgpu/display: drop DCN support for aarch64
From Ard:

"Simply disabling -mgeneral-regs-only left and right is risky, given that
the standard AArch64 ABI permits the use of FP/SIMD registers anywhere,
and GCC is known to use SIMD registers for spilling, and may invent
other uses of the FP/SIMD register file that have nothing to do with the
floating point code in question. Note that putting kernel_neon_begin()
and kernel_neon_end() around the code that does use FP is not sufficient
here, the problem is in all the other code that may be emitted with
references to SIMD registers in it.

So the only way to do this properly is to put all floating point code in
a separate compilation unit, and only compile that unit with
-mgeneral-regs-only."

Disable support until the code can be properly refactored to support this
properly on aarch64.

4b6b7437b1 drm/amd/display: Enable fp16 also on DCE-8/10/11.
The hw supports fp16, this is not only useful for HDR,
but also for standard dynamic range displays, because
it allows to get more precise color reproduction with
about 11 - 12 bpc linear precision in the unorm range
0.0 - 1.0.

Working fp16 scanout+display (and HDR over HDMI) was
verified on a DCE-8 asic, so i assume that the more
recent DCE-10/11 will work equally well, now that
format-specific plane scaling constraints are properly
enforced, e.g., the inability of fp16 to scale on older
hw like DCE-8 to DCE-11.

This takes hw constraints specific to pixel formats into account,
e.g., the inability of older hw to scale fp16 format framebuffers.

It should now allow safely to enable fp16 formats also on DCE-8,
DCE-10, DCE-11.0

71338cb4a7 drm/amd/display: enable idle optimizations for linux (MALL stutter)
[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

61d791365b drm/amd/display: avoid uninitialized variable warning
clang (quite rightly) complains fairly loudly about the newly added
mpc1_get_mpc_out_mux() function returning an uninitialized value if the
'opp_id' checks don't pass.

This may not happen in practice, but the code really shouldn't return
garbage if the sanity checks don't pass.

So just initialize 'val' to zero to avoid the issue.

a135a1b4c4 drm/amd/display: Fix memory leaks in S3 resume
EDID parsing in S3 resume pushes new display modes
to probed_modes list but doesn't consolidate to actual
mode list. This creates a race condition when
amdgpu_dm_connector_ddc_get_modes() re-initializes the
list head without walking the list and results in  memory leak.

[Why]
We defer clock updates to after pipes have been programmed. In
some instances we use DPPCLK that have been previously set to be
"unused". This results in a brief window of time where underflow
could occur.

[How]
During prepare bandwidth allow rn_update_clocks_update_dpp_dto

If new clock is higher than previous clock, program DPPDTO.

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.

25331a18f4 drm/amd/display: Don't check seamless boot in power down HW by timeout

power_down_on_boot is designed to power down HW when set mode is not
called before timeout. It can happen in headless system or booting with
the display is output by non-AMD GPU only.
The function will be executed only if it's not seamless boot. So in
seamless boot, the HW is still on.
It's not necessary to check this since there's no display data in both
cases.

Previously we accepted non-linear buffers for the cursor plane. This
results in bad output, DC validation failures and oops.

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.

079204508e drm/amd/display: Check link_active instead of lane_settings != unknown
[Why]
enable_link_dp_mst checks that cur_link_settings != unknown to determine
that the link is already enabled, to skip redundant enablement calls for
multiple streams on the same link. During dc_reinitialize_hardware,
cur_link_settings on previously-active links is not cleared, which blocks
MST links from being re-enabled after a reinitialization.

[How]
 - check for link_status->link_active instead, as it's the real intent
 - clear cur_link_settings when we clear link_active

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.

e97978e812 drm/amd/display: add i2c speed arbitration for dc_i2c and hdcp_i2c
[why]
HDCP 1.4 failed on SL8800 SW w/a test driver use.

[how]
slower down the HW i2c speed when used by HW i2c.
this request: each acquired_i2c_engine setup the i2c speed needed.
and set the I2c engine for HDCP use at release_engine.

this covers SW using HW I2c engine and HDCP using HW I2c engine. for
dmcu using HW I2c engine, needs add similar logic in dmcufw.

drm: Pass the full state to connectors atomic functions
The current atomic helpers have either their object state being passed as
an argument or the full atomic state.

The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.

Now that the CRTCs have been converted, let's move forward with the
connectors to provide a consistent interface.

The conversion was done using the coccinelle script below, and built tested
on all the drivers.

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.

fa896813b4 drm/amd/display: Prevent freesync power optimization during validation
[Why]
Due to the freesync power optimization increasing vtotal, the driver
believes that MPO is supported. MPO is turned on. Freesync then
exits, MPO can no longer be supported and immediate flip fails. This
causes corruption on the panel.

[How]
Avoid the freesync optimization when doing validation so in the case
freesync exits, driver can still support the configuration.

[Why]
In some cases, prefetch mode 0 is unsupported but prefetch 1 is
supported. Due to previous change always forcing prefetch mode to 0, we
are failing bandwidth validation in cases where we should not.

[How]
By default try prefetch mode 0 but in the case validation fails, attempt
to do prefetch mode 1 to see if it is supported.

Pull drm fixes from Dave Airlie:
 "It's Friday here so that means another installment of drm fixes to
  distract you from the counting process.

  Changes all over the place, the amdgpu changes contain support for a
  new GPU that is close to current one already in the tree (Green
  Sardine) so it shouldn't have much side effects.

  Otherwise imx has a few cleanup patches and fixes, amdgpu and i915
  have around the usual smattering of fixes, fonts got constified, and
  vc4/panfrost has some minor fixes. All in all a fairly regular rc3.

  We have an outstanding nouveau regression, but the author is looking
  into the fix, so should be here next week.

e6b0bd61a7 This pull contains a series of warning fixes from Mauro; once applied, the
number of warnings from the once-noisy docs build process is nearly zero.
 Getting to this point has required a lot of work; once there, hopefully we
 can keep things that way.
 
 I have packaged this as a separate pull because it does a fair amount of
 reaching outside of Documentation/.  The changes are all in comments and in
 code placement.  It's all been in linux-next since last week.

Merge tag 'docs-5.10-warnings' of git://git.lwn.net/linux

Pull documentation build warning fixes from Jonathan Corbet:
 "This contains a series of warning fixes from Mauro; once applied, the
  number of warnings from the once-noisy docs build process is nearly
  zero.

  Getting to this point has required a lot of work; once there,
  hopefully we can keep things that way.

  I have packaged this as a separate pull because it does a fair amount
  of reaching outside of Documentation/. The changes are all in comments
  and in code placement. It's all been in linux-next since last week"

8edb94562a drm/amd/display: WA to ensure MUX chip gets SUPPORTED_LINK_RATES of eDP
[Why]
Customer make a request to add this WA by driver.

Some MUX chips will power down with eDP 1.4 panel and
lose previous supported link rates(DPCD 0x010) in
customer's hybrid-GPU designs. As a result, during sleep
resuming and screen turns on from idle, link training
will be performed incorrectly and eDP will flicker or
black screen. These MUX chips need source to read DPCD
0x010 again during LKT so that it can restore supported
link rates of panel.

For driver side, supported link rate set is fetched when
link detection, no need to update but just read again
as WA.

[How]
Read DPCD 0x010 again during link training for eDP 1.4.

36f878501e drm/amd/display: Blank HUBP during pixel data blank for DCN30
[Why]
There are some timings for which we support p-state
switching in active, but not in blank. There was a
previous issue where a timing that had active-only
support would hang a p-state request when we were in
an extended blanking period. The workaround for that
issue was to block active-only p-state switching,
but that resulted in a lack of p-state support for
some common timings such as 1440p60. We want to fix
that issue properly by un-blocking p-state requests
while the display is blanked, so that we can re-enable
active-only p-state switching.

[How]
 - new version of blank_pixel_data for DCN30
 - call hubp->set_blank from dcn30_blank_pixel_data
 - blank every hubp in the mpcc tree, and odm tree
 - on blank enable, wait until the next frame before blanking HUBP

6f2239ccdf drm/amd/display: Keep GSL for full updates with planes that flip VSYNC
[Why]
When enabling PIP in Heaven, the PIP planes are VSYNC
flip and is also the top-most pipe. In this case GSL
will be disabled because we only check immediate flip
for the top pipe. However, the desktop planes are still
flip immediate so we should at least keep GSL on until
the full update.

[How]
Check each pipe in the tree to see if any planes
are flip immediate. Maintain the GSL lock if yes,
and take it down after when unlocking if any planes
are flipping VSYNC. Keeping GSL on with VSYNC +
flip immediate planes causes corruption.

drm/atomic: Pass the full state to CRTC atomic_check
The current atomic helpers have either their object state being passed as
an argument or the full atomic state.

The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.

Let's start convert all the remaining helpers to provide a consistent

dbb60031dd drm/amdgpu: fix build_coefficients() argument
gcc -Wextra warns about a function taking an enum argument
being called with a bool:

drivers/gpu/drm/amd/amdgpu/../display/modules/color/color_gamma.c: In function 'apply_degamma_for_user_regamma':
drivers/gpu/drm/amd/amdgpu/../display/modules/color/color_gamma.c:1617:29: warning: implicit conversion from 'enum <anonymous>' to 'enum dc_transfer_func_predefined' [-Wenum-conversion]
 1617 |  build_coefficients(&coeff, true);

It appears that a patch was added using the old calling conventions
after the type was changed, and the value should actually be 0
(TRANSFER_FUNCTION_SRGB) here instead of 1 (true).

faa37f54ce drm/amd/display: Expose modifiers.
This expose modifier support on GFX9+.

Only modifiers that can be rendered on the current GPU are
added. This is to reduce the number of modifiers exposed.

The HW could expose more, but the best mechanism to decide
what to expose without an explosion in modifiers is still
to be decided, and in the meantime this should not regress
things from pre-modifiers and does not risk regressions as
we make up our mind in the future.

v2:
  - Added comment that D on Raven is only valid for 64bpp
    and will be filtered based on format later.
  - Removed D tiling modes that weren't useful for 64bpp
    on GFX10+.

v4: Add AMDGPU_FAMILY_VGH case.

For DCC we will use 2/3 planes to avoid X rendering to the frontbuffer
with DCC compressed images. To make this work with the core KMS
validation we need to add extra formats with the extra planes.

However, due to flexibility we set bpp = 0 for the extra planes and
do the validation ourselves.

This commit introduces a trace mechanism for struct pipe_ctx by adding a
middle layer struct in the amdgpu_dm_trace.h for capturing the most

This tracepoint was added to dc.c and dcn10_hw_sequencer, however, it

9d83722d06 drm/amd/display: Decouple amdgpu_dm_trace from service
Our DC currently uses some of the tracepoint function inside a DC
header, which means that many other files implicitly include part of the
trace function. This situation limits how we can expand this feature for
other parts of the driver by generating multiple compilation errors when
we try to reuse some of the existing structures. This commit decouples
part of the amdgpu_dm_trace from DC core to simplify the trace
enlargement in future changes.

def48da790 drm/amd/display: Fix max brightness pixel accuracy
[WHY]
It was detected in some Freesync HDR tests that displays were not
reaching their maximum nominal brightness.

[HOW]
The Multi-plane combiner (MPC) Output Gamma (OGAM) block builds a
discrete Lookup Table (LUT). When the display's maximum brightness
falls in between two values, having to be linearly interpolated by
the hardware, rounding issues might occur that will cause the
display to never reach its maximum brightness.
The fix involves doing the calculations backwards, ensuring that
the interpolation in the maximum brightness values translates to an
output of 1.0.

4a3a1dc02f drm/amd/display: Initialize num_pkrs on VANGOGH.
As far a I can tell uses a variant of DCN3xx which uses num_pkrs.

If we do not initialize the variable we will set the register field
to ilog2(0) = -1, though the mask will reduce that to 7. Pretty sure
7 is not the value we want here.

44264591a8 drm/amd/display: Fix module load hangs when connected to an eDP
It was recently introduced a change that enables driver to disable
streams if pixel clock changes. Consequently, the code path executed in
the disable vbios function expanded to an encoder verification part.
The encoder loop is nested inside the pipe count loop, and both loops
share the 'i' variable in control of their flow. This situation may lead
to an infinite loop because the encoder loop constantly updates the `i`
variable, making the first loop always positive. As a result, we can see
a soft hang during the module load (modprobe amdgpu) and a series of
dmesg log that looks like this:

cd294f9a64 drm/amd/display: Fix module load hangs when connected to an eDP
It was recently introduced a change that enables driver to disable
streams if pixel clock changes. Consequently, the code path executed in
the disable vbios function expanded to an encoder verification part.
The encoder loop is nested inside the pipe count loop, and both loops
share the 'i' variable in control of their flow. This situation may lead
to an infinite loop because the encoder loop constantly updates the `i`
variable, making the first loop always positive. As a result, we can see
a soft hang during the module load (modprobe amdgpu) and a series of
dmesg log that looks like this:

7c4ed1df0a drm/amd/display: Copy WM values from set A to other sets in hw_init
[Why]
When we transfer the WM range table to SMU, they can perform a watermark
switch right away. This can be a problem if we're in not in accelerated mode
during hw_init as SMU may initiate a dummy p-state change before the rest
of the watermarks are programmed. Watermark set A is defined to be
sufficient for all cases, so we can copy the values from set A to all other
sets, avoiding any issues from SMU doing WM switches.

[How]
 - new hubbub func init_watermarks
 - copy register values from set A to all other sets
 - call init_watermarks before calling notify_wm_ranges

3e19095534 drm/amd/display: Force enable pstate on driver unload
[Why]
During driver unload, it is expected that p-state switching is supported.
If it's not supported, PMFW will hang due to a forced p-state switch. Even
if the current timing does not support p-state normally, we still want to
force allow because the worst that can happen is underflow. This will
match Navi10 behaviour.

[How]
 - new hubbub func to control the force pstate register
 - force allow when releasing display ownership
   - registers are inaccessible after due to m_cgs.hwNotAvailable
 - explicitly disable force signal during hw_init
   - if driver is disabled and re-enabled, register not cleared otherwise

Also, remove DCN3 part of dcn10_init_hw, we will not be going back to it.

f7fb81a18f drm/amd/display: Check for flip pending before locking pipes
[Why]
When running games or benchmarking with v-sync disabled, disabling
a plane (which is v-sync) can cause underflow. This is caused by
flips pending before pipe locking being applied after locks are
released and pipes could have been re-arranged or disconnected. This
could potentially apply a flip on incorrect pipe. Also, previous logic
of always locking pipes was unnecessary.

[How]
Only lock the pipes when there is a pipe being disabled to increase
efficiency. Before the pipes are locked, check that any pending flips
are cleared to ensure the flips are applied to the correct pipe.

95d620adb4 drm/amd/display: HDMI remote sink need mode validation for Linux
[Why]
Currently mode validation is bypassed if remote sink exists. That
leads to mode set issue when a BW bottle neck exists in the link path,
e.g., a DP-to-HDMI converter that only supports HDMI 1.4.

Any invalid mode passed to Linux user space will cause the modeset
failure due to limitation of Linux user space implementation.

[How]
Mode validation is skipped only if in edid override. For real remote
sink, clock limit check should be done for HDMI remote sink.

Have HDMI related remote sink going through mode validation to
elimiate modes which pixel clock exceeds BW limitation.

2f8be0e516 drm/amd/display: Avoid set zero in the requested clk
[Why]
Sometimes CRTCs can be disabled due to display unplugging or temporarily
transition in the userspace; in these circumstances, DCE tries to set
the minimum clock threshold. When we have this situation, the function
bw_calcs is invoked with number_of_displays set to zero, making DCE set
dispclk_khz and sclk_khz to zero. For these reasons, we have seen some
ATOM bios errors that look like:

[drm:atom_op_jump [amdgpu]] *ERROR* atombios stuck in loop for more than
5secs aborting
[drm:amdgpu_atom_execute_table_locked [amdgpu]] *ERROR* atombios stuck
executing EA8A (len 761, WS 0, PS 0) @ 0xEABA

[How]
This error happens due to an attempt to optimize the bandwidth using the
sclk, and the dispclk clock set to zero. Technically we handle this in
the function dce112_set_clock, but we are not considering the case that
this value is set to zero. This commit fixes this issue by ensuring that
we never set a minimum value below the minimum clock threshold.

69fc1f4b97 amd/drm/display: avoid dcn3 on flip opp change for slave pipes
At the moment on flip opp reassignment does not work in all cases
for non root pipes.
This change simply makes sure we prefer pipes not used previously
when splitting in dcn3.

8353d30e74 drm/amd/display: disable stream if pixel clock changed with link active
[Why]
Vbios uses preferred timing to turn on edp but OS could use other
timing.  If change pixel clock when link active, there is unexpected
garbage on monitor.

[How]
Once pixel clock changed, the driver needs to disable stream.

8e02c26a58 drm/amd/display: Calc DLG from dummy p-state if full p-state unsupported
[Why]
Currently, when full p-state changes are not supported, DLG parameters
are calculated for no p-state support at all. However, we are required
to always support dummy p-state changes, so we should instead calculate
DLG based on dummy p-state latency when full p-state is unsupported.
This behaviour already exists for DCN2.

[How]
 - move DLG calculation inside WM calculation
 - if p-state unsupported, do not recalculate for set A, instead copy from
set C, and perform DLG calculation with dummy p-state latency

99d1437aa0 drm/amd/display: Check for flip pending before locking pipes.
[Why]
When running a game/benchmark with v-sync disabled, disabling a plane
(which is v-sync) can cause an underflow. This is due to flips that are
pending before pipe locking being applied after locks are released and
pipes have been re-arranged or disconnected. This can potentially apply
a flip on the incorrect pipe.

[How]
Check that any pending flips are cleared before locking any pipes to
ensure flips are applied on the correct pipes.

disabled (e.g. due to destroying the FB assigned to the primary plane,
as happens e.g. with mutter in Wayland mode):

* The legacy cursor ioctl returned EINVAL for a non-0 cursor FB ID
  (which enables the cursor plane).
* If the cursor plane was enabled, changing the legacy DPMS property
  value from off to on returned EINVAL.

v2:
* Minor changes to code comment and commit log, per review feedback.

There are situations where we go from 2 pipe to 1 pipe in MPO, but this

disable the pipe in a separate operation from the rest of the pipe

separate operation when we're actually disabling pipe split.

offset. All other pipes should have recout offset 0;
otherwise there will be gaps in the image.

Set recout.x to 0 if the pipe is not the leftmost ODM pipe.

When computing viewports, calculate the horizontal offset of a pipe's src
based on the current pipe's position in the ODM group, plus whatever offset the
leftmost ODM pipe has; otherwise there will be discontinuity in the image.

Since ODM combine can only combine pipes horizontally, nothing needs to

498563cf9c drm/amd/display: Detect plane change when detect pipe change.
[Why]
If plane has changed, dcn20_detect_pipe_changes doesn't update dc_plane_state->update_flags, and the following dcn20_program_pipe can't reprogram hubp correctly.

[How]
Add a new flags bit "plane_changed" in pipe_ctx->update_flags.If old plane isn’t identical to new plane, this bit will be set and guide “dcn20_program_pipe” to programing HUBP correctly.

168f09cdad drm/amd/display: Reject overlay plane configurations in multi-display scenarios
[Why]
These aren't stable on some platform configurations when driving
multiple displays, especially on higher resolution.

In particular the delay in asserting p-state and validating from
x86 outweights any power or performance benefit from the hardware
composition.

Under some configurations this will manifest itself as extreme stutter
or unresponsiveness especially when combined with cursor movement.

[How]
Disable these for now. Exposing overlays to userspace doesn't guarantee
that they'll be able to use them in any and all configurations and it's
part of the DRM contract to have userspace gracefully handle validation
failures when they occur.

Valdiation occurs as part of DC and this in particular affects RV, so
disable this in dcn10_global_validation.

69d9f4278d drm/amd/display: use correct scale for actual_brightness
Documentation for sysfs backlight level interface requires that
values in both 'brightness' and 'actual_brightness' files are
interpreted to be in range from 0 to the value given in the
'max_brightness' file.

With amdgpu, max_brightness gives 255, and values written by the user
into 'brightness' are internally rescaled to a wider range. However,
reading from 'actual_brightness' gives the raw register value without
inverse rescaling. This causes issues for various userspace tools such
as PowerTop and systemd that expect the value to be in the correct
range.

Introduce a helper to retrieve internal backlight range. Use it to
reimplement 'convert_brightness' as 'convert_brightness_from_user' and
introduce 'convert_brightness_to_user'.
