4067f4fa04 drm/amd/display: Initialize get_bytes_per_element's default to 1
Variables, used as denominators and maybe not assigned to other values,
should not be 0. bytes_per_element_y & bytes_per_element_c are
initialized by get_bytes_per_element() which should never return 0.

This fixes 10 DIVIDE_BY_ZERO issues reported by Coverity.

a15268787b drm/amd/display: Avoid overflow assignment in link_dp_cts
sampling_rate is an uint8_t but is assigned an unsigned int, and thus it
can overflow. As a result, sampling_rate is changed to uint32_t.

Similarly, LINK_QUAL_PATTERN_SET has a size of 2 bits, and it should
only be assigned to a value less or equal than 4.

This fixes 2 INTEGER_OVERFLOW issues reported by Coverity.

bd870cfd21 drm/amd/display: Add seamless boot support for more DIG operation modes
[Why]
When pre-OS firmware enables display support for displays that operate
the DIG in 2 pixels per cycle processing modes the inferred pixel rate
from get_pixel_clk_frequency_100hz does not account for the true pixel
rate since we're outputting 2 per cycle past the stream encoder.

This causes seamless boot validation to abort early.

[How]
Add a new stream encoder function for getting pixels per cycle from the
stream encoder. If the pixels per cycle is greater than 1 and the driver
policy is to enable 2 pixels per cycle for post-OS then allow seamless
boot to continue.

fcb3a4fb82 drm/amd/display: Request 0MHz dispclk for zero display case
[Why]
If we aren't entering RCG/IPS2 or CLKSTOP is not supported by PMFW then
we should be requesting a dispclk value of 0MHz to PMFW.

Currenly we run at max clock since there's an assumption in APU clock
table formulation where we can run at any DISPCLK at any state so the
real clock value ends up as 1200Mhz - the maximum.

[How]
Set to 0 instead of the minimum value in the state array.

08ae395ea2 drm/amd/display: Add null check for set_output_gamma in dcn30_set_output_transfer_func
This commit adds a null check for the set_output_gamma function pointer
in the  dcn30_set_output_transfer_func function. Previously,
set_output_gamma was being checked for nullity at line 386, but then it
was being dereferenced without any nullity check at line 401. This
could potentially lead to a null pointer dereference error if
set_output_gamma is indeed null.

To fix this, we now ensure that set_output_gamma is not null before
dereferencing it. We do this by adding a nullity check for
set_output_gamma before the call to set_output_gamma at line 401. If
set_output_gamma is null, we log an error message and do not call the
function.

This fix prevents a potential null pointer dereference error.

4b6377f0e9 drm/amd/display: Add NULL check for clk_mgr and clk_mgr->funcs in dcn401_init_hw
This commit addresses a potential null pointer dereference issue in the
`dcn401_init_hw` function. The issue could occur when `dc->clk_mgr` or
`dc->clk_mgr->funcs` is null.

The fix adds a check to ensure `dc->clk_mgr` and `dc->clk_mgr->funcs` is
not null before accessing its functions. This prevents a potential null
pointer dereference.

bdf6068102 drm/amd/display: Implement bounds check for stream encoder creation in DCN401
'stream_enc_regs' array is an array of dcn10_stream_enc_registers
structures. The array is initialized with four elements, corresponding
to the four calls to stream_enc_regs() in the array initializer. This
means that valid indices for this array are 0, 1, 2, and 3.

The error message 'stream_enc_regs' 4 <= 5 below, is indicating that
there is an attempt to access this array with an index of 5, which is
out of bounds. This could lead to undefined behavior

Here, eng_id is used as an index to access the stream_enc_regs array. If
eng_id is 5, this would result in an out-of-bounds access on the
stream_enc_regs array.

Thus fixing Buffer overflow error in dcn401_stream_encoder_create

fae1879dc2 drm/amd/display: Check top sink only when multiple streams for DP2
[why]
When switching from extended to second display only
mode, the top remote sink is not removed while the top stream
itself is released. This causes DML to think there is no
DP2 output encoder because top remote sink does not match
with the second stream and disables DTBCLK and causes
hang.

[how]
For DP2.0 MST hubs, only treat 1st remote sink as an encoder
only when there are multiple displays connected.

218784049f drm/amd/display: avoid disable otg when dig was disabled
[Why]
This is a workaround for an dcn3.1 hang that happens if otg dispclk
is ramped while otg is on and stream enc is off.
But this w/a should not trigger when we have a dig active.

[How]
Avoid disable otg when dig FE/BE FIFO was not switched.

5fc77c2697 drm/amd/display: apply vmin optimization even if it doesn't reach vmin level
[why]
Based on power measurement result, in most cases when display clock is higher
than Vmin display clock, lowering display clock using dynamic ODM will improve
overall power consumption by 0 to 4 watts even if we can't reach Vmin.

3c9154310a drm/amd/display: fix dscclk programming sequence on DCN401
[why]
The mux to switch between refclk and dto_dsc_clk is non double buffered.
However dto dsc clk's phase and modulo divider registers are currently
configured as double buffered update. This causes a problem when we switch to
use dto dsc clk and program phase and modulo in the same sequence. In this
sequence dsc clk is switched to dto but the clock divider programming doesn't
take effect until next frame. When we try to program DSCC registers, SMN bus
will hang because dto dsc clk divider phase is set to 0.

[how]
Configure phase and modulo to take effect immediately. Always switch to dto dsc
clk before DSC clock is unagted. Switch back to refclk after DSC clock is gated.

e8d77cfdd2 drm/amd/display: Replace assert with error message in dp_retrieve_lttpr_cap()
[Why]
When assert in dp_retrieve_lttpr_cap() is hit, dmesg has traces like:

 RIP: 0010:dp_retrieve_lttpr_cap+0xcc/0x1a0 [amdgpu]
 Call Trace:
 <TASK>

  report_bug+0x1e8/0x240

  link_detect+0x35/0x580 [amdgpu]

It happens when LTTPRs fail to increment dpcd repeater count.
We have a recovery action in place for such cases.
Assert is misleading, an indicative error in dmesg is more useful.

[How]
Remove ASSERT and use DC_LOG_ERROR instead.

For no plane scenarios we should not consider cursor as there cannot
be any cursor if  there's no planes. This fixes an issue where
dc_commit_streams fails due to prefetch bandwidth requirements
(the display config + dummy planes + cursor causes the prefetch
bandwidth to exceed what is possible).

95134e5852 drm/amd/display: Add ASIC cap to limit DCC surface width
[Why]
Certain configurations of DCN401 require ODM4:1 to support DCC for 10K
surfaces. DCC should be conservatively disabled in those cases.

The issue is that current logic limits 10K surface DCC for all
configurations of DCN401.

[How]
Add DC ASIC cap to indicate max surface width that can support DCC.
Disable DCC if this ASIC cap is non-zero and surface width exceeds it.

73b8a388eb drm/amd/display: Choose HUBP unbounded request based on DML output
[why]
Previously, we decide on the unbounded request
purely based on pipe_cnt which is a wrong variable
to use to determine how many pipes are in "use".
DML already accounts for number of pipes in use
along with other various factors and is a more reliable
method of determination.

[how]
Use UnboundedRequestEnabledThisState to decide
on unbounbded_req_enabled.

c6dfe8f20b drm/amd/display: Remove unnecessary variable
[WHY]
Coverity analysis flagged this code as DEADCODE because
the condition '(!need_recovery)' is never true.

The variable 'need_recovery' is initialized as 'true',
is not assigned to 'false' anywhere before the
conditional statement.

Since the variable is only used for the conditional check,
but the check can never be true, the variable itself is
redundant.

This was then used to determine if the symclk could be disabled, if all
FEs were disconnected. However, the function would skip over the primary
FE and return 0 when the primary FE was still connected. This caused black
screens on driver disable with an MST daisy chain hooked up.

This warning is triggered by a check in the function
resource_get_opp_heads_for_otg_master that validates if the request
operation is in a master OTG pipe; if not, the warning above is
displayed. In other words, another part of the code might be calling
this function in a non-OTG master pipe context, resulting in the log
message.

The reason the ASSERT was triggered is that the current state wasn't
updated after applying the context to the hardware. This means that the
update_dsc_for_odm_change might be called from a non-OTG-MASTER. To
prevent this, it's crucial to check if the current reference is pointing
to an OTG master before operate in the old OTG master reference. If it's
not, the function must set the old OTG reference to NULL and avoid
calling resource_get_opp_heads_for_otg_master before the context is
updated.

This error happens when the color log tries to read the gamut remap
information from DCN401 which is not initialized in the dcn401_dpp_funcs
which leads to a null pointer dereference. This commit addresses this
issue by adding a proper guard to access the gamut_remap callback in
case the specific ASIC did not implement this function.

37256027b4 drm/amd/display: Attempt to avoid empty TUs when endpoint is DPIA
[WHY]
Empty SST TUs are illegal to transmit over a USB4 DP tunnel.
Current policy is to configure stream encoder to pack 2 pixels per pclk
even when ODM combine is not in use, allowing seamless dynamic ODM
reconfiguration. However, in extreme edge cases where average pixel
count per TU is less than 2, this can lead to unexpected empty TU
generation during compliance testing. For example, VIC 1 with a 1xHBR3
link configuration will average 1.98 pix/TU.

[HOW]
Calculate average pixel count per TU, and block 2 pixels per clock if
endpoint is a DPIA tunnel and pixel clock is low enough that we will
never require 2:1 ODM combine.

52971387a0 drm/amd/display: DCN401 full power down in HW init if any link enabled
[Why]
During HW init, certain operations the driver performs are invalid on
enabled hardware in an unknown state (for example, setting all clock
values to minimum when the GPU is actively driving a display). There is
already code present to call HWSS->power_down during init when any link
is enabled in HW, but that function pointer is unpopulated for most asics.
We want to enable this codepath for DCN401, as it resolves the issue with
being unable to drive certain display configs on adapter re-enable, and we
can restore boot optimizations.

[How]
 - add power_down HWSS function for DCN401
 - remove debug bit to disable boot optimizations for DCN401

fe6f61d472 drm/amd/display: Remove reduntant comparisons by Coverity
[WHY]
Coverity analysis of the Upstream display driver code
(amd-staging-drm-next) flagged these three functions as
containing 'CONSTANT_EXPRESSION_RESULT' errors, i. e. the
conditionals are reduntant since their result is predetermined.

fixpt31_32.c:
The two flagged 'ASSERT' lines redundant since they are always true:
- LONG_MAX equals to the largest 'signed long long' number
- res.value is type 'signed long long',

So, the condition inside the 'ASSERTS's is always

link_dp_training.c:
The flagged conditional statement is always false:
- 'max_requested.FFE_PRESET.settings.level' is 4 bits, so its max
  possible value is 15
- 'DP_FFE_PRESET_MAX_LEVEL' equals to 15.

So, the conditional statement is always false and the wrapped code
never executes.

[HOW]
Removed lines flagged by Coverity analysis.

7c70e60fbf drm/amd/display: Disable DMCUB timeout for DCN35
[Why]
DMCUB can intermittently take longer than expected to process commands.

Old ASIC policy was to continue while logging a diagnostic error - which
works fine for ASIC without IPS, but with IPS this could lead to a race
condition where we attempt to access DCN state while it's inaccessible,
leading to a system hang when the NIU port is not disabled or register
accesses that timeout and the display configuration in an undefined
state.

[How]
We need to investigate why these accesses take longer than expected, but
for now we should disable the timeout on DCN35 to avoid this race
condition. Since the waits happen only at lower interrupt levels the
risk of taking too long at higher IRQ and causing a system watchdog
timeout are minimal.

c006d1a15a drm/amd/display: remove ODM combine before bandwidth validation
[why]
DML1 validation code doesn't have the ability to remove ODM combine.
It will directly translate currently used ODM combine config into ODM
override. If ODM combine is used in the initial state it will only
validate the timing if ODM is used. This is not correct for dynamic ODM u
se case, as ODM is used as an optimization not a hard requirement.

[how]
Remove ODM combine in the initial state before bandwidth validation so
DML will not translate it into ODM override in the initial bandwidth
validation.

[why]
There are cases where update pipe params could fail but dpp pipes are already
added to the state. In this case, we should remove dpp pipes so dc state is
restored back. If it is not restored, dc state is corrupted after calling this
function, so if we call the same interface with the corrupted state again, we
may end up programming pipe topology based on a corrupted dc state.

9a29c4adb0 drm/amd/display: reduce ODM slice count to initial new dc state only when needed
[why]
We need to decrease ODM slice when adding or removing planes because MPO
support takes precedence over dynamic ODM combine. However there is a case where
we remove ODM combine even for ODM combine required timing in the initial new
dc state. This is normally okay because ODM will be added back after we pass DML
bandwidth validation. However since we remove ODM combine in the initial new
state, the previous ODM pipe allocation is lost. This may cause the new plane to
take away the original secondary OPP head pipe that is still required in the new
state.

For a timing that requires ODM 2:1 but optimized with ODM 4:1, if we add an MPO
plane, we will not have enough pipe to preserve ODM 4:1. In this case we should
reduce ODM slice count then try to add the MPO plane again. By reducing, we are
gradually remove 1 ODM slice from right most side one at a time until we have
enough free pipes for the new plane. If we remove ODM combine entirely, we could
use the pipe at ODM slice index 1 as a DPP pipe for the new plane. But ODM slice
1 is still needed as the timing requires ODM 2:1. This transition is not
seamless and user will see corruption on the screen.

[how]
Remove single ODM slice one at time until we have enough pipes for a new plane.
Remove previous logic to always remove ODM combine entirely.

interface only supports either ALPM or PHY mode

[How]
Modify the interface for supporting different types of Replay residency
calculation.

3601a35a2e drm/amd/display: Wake DMCUB before sending a command for replay feature
[Why]
We can hang in place trying to send commands when the DMCUB isn't
powered on.

[How]
For functions that execute within a DC context or DC lock we can wrap
the direct calls to dm_execute_dmub_cmd/list with code that exits idle
power optimizations and reallows once we're done with the command
submission on success.

For DM direct submissions the DM will need to manage the enter/exit
sequencing manually.

We cannot invoke a DMCUB command directly within the DM execution helper
or we can deadlock.

program DIG_FE_SOURCE_SELECT for all DIO scenarios (DVI in this
particular case) before going through the PHY / DIG enable sequence.

15c2990e0f drm/amd/display: Add null checks for 'stream' and 'plane' before dereferencing
This commit adds null checks for the 'stream' and 'plane' variables in
the dcn30_apply_idle_power_optimizations function. These variables were
previously assumed to be null at line 922, but they were used later in
the code without checking if they were null. This could potentially lead
to a null pointer dereference, which would cause a crash.

The null checks ensure that 'stream' and 'plane' are not null before
they are used, preventing potential crashes.

Fixes the below static smatch checker:
drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn30/dcn30_hwseq.c:938 dcn30_apply_idle_power_optimizations() error: we previously assumed 'stream' could be null (see line 922)

5d74be8c3a drm/amd/display: fix YUV video color corruption in DCN401
[Why]
Missing check causes sequence error which results in chroma
 filter coefficients not being updated in certain modes
 when we display YUV video in fullscreen.  This results in
 color corruption in video

[How]
Add back chroma_coef_mode check in dscl_set_scl_filter
 so that filter coefficients are calculated and updated when
 we have YUV surface

e69d43356f drm/amd/display: Move fpo_in_use to stream_status
[Description]
Refactor code and move fpo_in_use into stream_status to avoid
unexpected changes to previous dc_state (i.e., current_state).
Since stream pointers are shared between current and new dc_states,
updating parameters of one stream will update the other as well
which causes unexpected behaviors (i.e., checking that fpo_in_use
isn't set in previous state and set in the new state is invalid).
To avoid incorrect updates to current_state, move the fpo_in_use flag
into dc_stream_status since stream_status is owned by dc and are not
shared between different dc_states.

4621e10e01 drm/amd/display: Only program P-State force if pipe config changed
[Description]
Today for MED update type we do not call update clocks. However, for FPO
the assumption is that update clocks should be called to disable P-State
switch before any HW programming since FPO in FW and driver are not
synchronized. This causes an issue where on a MED update, an FPO P-State
switch could be taking place, then driver forces P-State disallow in the below
code and prevents FPO from completing the sequence. In this case we add a check
to avoid re-programming (and thus re-setting) the P-State force register by
only reprogramming if the pipe was not previously Subvp or FPO. The assumption
is that the P-State force register should be programmed correctly the first
time SubVP / FPO was enabled, so there's no need to update / reset it if the
pipe config has never exited SubVP / FPO.

0b6dc64b4e drm/amd/display: Refactor construct_phy function in dc/link/link_factory.c
This commit modifies the construct_phy function to handle the case where
`bios->integrated_info` is NULL and to address a compiler warning about
a large stack allocation.

Upon examination, it was found that the local `integrated_info`
structure was just used to copy values which is large and was being
declared directly on the stack which could potentially lead to
performance issues. This commit changes the code to use
`bios->integrated_info` directly, which avoids the need for a large
stack allocation.

The function now checks if `bios->integrated_info` is NULL before
entering a for loop that uses it. If `bios->integrated_info` is NULL,
the function skips the for loop and continues executing the rest of the
code. This ensures that the function behaves correctly when
`bios->integrated_info` is NULL and improves compatibility with dGPUs.

Fixes the below with gcc W=1:
drivers/gpu/drm/amd/amdgpu/../display/dc/link/link_factory.c: In function ‘construct_phy’:
drivers/gpu/drm/amd/amdgpu/../display/dc/link/link_factory.c:743:1: warning: the frame size of 1056 bytes is larger than 1024 bytes [-Wframe-larger-than=]

fa3c5a8edc drm/amd/display: Not fallback if link BW is smaller than req BW
[Why]
When the link BW is smaller than the request BW,
the DP LT just kept running and fallback to lower link config.
DP LT just aborted if is_hpd_pending bit is high.
But is_hpd_pending bit indicates a new HPD event received.
It doesn't mean the HPD is low.

[How]
Abort the DP LT if the link BW is smaller than the request BW.
Remove checking is_hpd_pending bit in DP LT.

3aec7a5af4 drm/amd/display: Fix pipe addition logic in calc_blocks_to_ungate DCN35
[Why]

Missing check for when there is new pipe configuration but both cur_pipe
and new_pipe are both populated causing update_state of DSC for that
instance not being updated correctly.

This causes some display mode changes to cause underflow since DSCCLK
is still gated when the display requires DSC.

[How]

Added another condition in the new pipe addition branch that checks if
there is a new pipe configuration and if it is not the same as cur_pipe.
cur_pipe does not necessarily have to be NULL to go in this branch.

61f880039e drm/amd/display: Reduce I2C speed to 95kHz in DCN401
[WHY]
HW for DCN401 is presented with a small I2C speed fluctuation that
exceeds the hard cap limitation of 100kHz occasionally. This violates
compliance requirement and will result in failure in compliance.

[HOW]
After various measurements and traceback to previous generation HW, DCN IP,
SI and SW driver agrees that we can reduce I2C speed to 95kHz to address
the I2C spped fluctuation in DCN401.

6ac05ae5ff drm/amd/display: Allow higher DSC slice support for small timings on dcn401
[WHY]
DML2.1 has added the support to determine ODM combine based on DSC slice
count limitation. This support would allow us to support DSC slice higher
than 4 on small timings. The change will allow higher DSC slice support
independent from pixel clock in use.

[HOW]
Add a DCN401 get_enc_caps function to allow the support for DSC slice count
higher than 4.

1dd50e634c drm/amd/display: Don't offload flip if not only address update
[WHAT & HOW]
Fast updates can consist of some stream updates as well (i.e., out_csc).
In these cases we should not offload the flip to FW as we can only
offload address only updates to FW.

UHBR13.5 support is optional, even if UHBR20 is supported by the device.
If source supports max UHBR13.5 while sink, cable and LTTPR support
UHBR20 but not UHBR13.5, UHBR10 should be used as the max link cap.

f9d48a88eb drm/amd/display: Add left edge pixel for YCbCr422/420 + ODM pipe split
[WHY]
Currently 3-tap chroma subsampling is used for YCbCr422/420. When ODM
pipesplit is used, pixels on the left edge of ODM slices need one extra
pixel from the right edge of the previous slice to calculate the correct
chroma value.

Without this change, the chroma value is slightly different than
expected. This is usually imperceptible visually, but it impacts test
pattern CRCs for compliance test automation.

[HOW]
Update logic to use the register for adding extra left edge pixel for
YCbCr422/420 ODM cases.

7662bc61c0 drm/amd/display: Disable AC/DC codepath when unnecessary
[WHY]
If there are no DC clock limits present, or if the DC limits are the same
as the AC limits, we can disable the AC/DC codepath as there won't be any
validation differences between the two modes.

[HOW]
When all DC power mode clock limits are the same as the max clock
values, there won't be any difference between AC mode and DC mode. Zero
out DC limits that equal max and provide a new cap to indicate the
presence of any non-zero DC mode limit. In summary:
 - zero out DC limits that are the same as max clock value
 - new dc cap to indicate the presence of DC mode limits
 - set limits present if any clock has distinct AC and DC values from SMU

c6f79832b8 drm/amd/display: Remove redundant NULL check in dcn10_set_input_transfer_func
This commit removes an unnecessary NULL check in the
`dcn10_set_input_transfer_func` function in the `dcn10_hwseq.c` file.
The variable `tf` is assigned the address of
`plane_state->in_transfer_func` unconditionally, so it can never be
`NULL`. Therefore, the check `if (tf == NULL)` is unnecessary and has
been removed.

Fixes the below smatch warning:

2fde4fdddc drm/amd/display: Avoid -Wenum-float-conversion in add_margin_and_round_to_dfs_grainularity()
When building with clang 19 or newer (which strengthened some of the
enum conversion warnings for C), there is a warning (or error with
CONFIG_WERROR=y) around doing arithmetic with an enumerated type and a
floating point expression.

  drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_dpmm/dml2_dpmm_dcn4.c:181:58: error: arithmetic between enumeration type 'enum dentist_divider_range' and floating-point type 'double' [-Werror,-Wenum-float-conversion]

        |                                  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~
  1 error generated.

This conversion is expected due to the nature of the enumerated value
and definition, so silence the warning by casting the enumeration to an
integer explicitly to make it clear to the compiler.

46fe9cb1a9 drm/amd/display: Allocate zero bw after bw alloc enable
[Why]
During DP tunnel creation, CM preallocates BW and reduces
estimated BW of other DPIA. CM release preallocation only
when allocation is complete. Display mode validation logic
validates timings based on bw available per host router.
In multi display setup, this causes bw allocation failure
when allocation greater than estimated bw.

[How]
Do zero alloc to make the CM to release preallocation and
update estimated BW correctly for all DPIAs per host router.

I introduced a "data" pointer so that I could replace

[Description]
For FPO + Vactive scenarios we must check that all non-FPO pipes
have VACTIVE margin to allow it. The previous check only confirmed
that there is at least one pipe that has vactive margin, but this
is incorrect as the vactive display could be using two pipes (MPO)
where the desktop plane has vactive margin, and the video plane
does not.

3351c608f3 drm/amd/display: Only program P-State force if pipe config changed
[Description]
Today for MED update type we do not call update clocks. However, for FPO
the assumption is that update clocks should be called to disable P-State
switch before any HW programming since FPO in FW and driver are not
synchronized. This causes an issue where on a MED update, an FPO P-State
switch could be taking place, then driver forces P-State disallow in the below
code and prevents FPO from completing the sequence. In this case we add a check
to avoid re-programming (and thus re-setting) the P-State force register by
only reprogramming if the pipe was not previously Subvp or FPO. The assumption
is that the P-State force register should be programmed correctly the first
time SubVP / FPO was enabled, so there's no need to update / reset it if the
pipe config has never exited SubVP / FPO.

66eba12a54 drm/amd/display: Do cursor programming with rest of pipe
Cursors are always programmed independently of updates on other
planes. When atomic commits program cursor and surface updates
together the cursor update might be locked out by the surface
update and not take effect.

To combat this program cursor and surface updates together via
dc_update_planes_and_stream to ensure they can be applied
atomically.

When cursor updates come on their own use the old method
to program the cursor as dc_update_planes_and_stream isn't
handling this case correctly (yet), leading to a flickering
screen.

f63f86b5af drm/amd/display: Separate setting and programming of cursor
We're seeing issues when user-space tries to do an atomic update of
the primary surface, as well as the cursor. These two updates are
separate calls into DC and don't currently act as an atomic update.
This might lead to cursor updates being locked out and cursors
stuttering.

In order to solve this problem we want to separate the setting
and programming of cursor attributes and position. That's what
we're doing in this patch. The subsequent patch will then be
able to use the cursor setters in independent cursor updates,
as well as in atomic commits.

During DP tunnel creation, CM preallocates BW and reduces
estimated BW of other DPIA. CM release preallocation only
when allocation is complete. Display mode validation logic
validates timings based on bw available per host router.
In multi display setup, this causes bw allocation failure
when allocation greater than estimated bw.

b01d98caba drm/amd/display: Skip SST ACT polling when sink_count is 0
[Why]
Upon disconnecting a UHBR SST display, the disconnection and the
SetTimings to disable the display can occur such that link_set_dpms_off
occurs after the disconnection has already processed
(link->type is dc_connection_none). Thus, the AUX related
operations should be skipped when clearing the payload allocation table.

aa463cc850 drm/amd/display: Fix CFLAGS for dml2_core_dcn4_calcs.o
-Wframe-larger-than=2048 is a part of both CFLAGS and CFLAGS_REMOVE for
dml2_core_dcn4_calcs.o, which means that it ultimately gets removed
altogether for 64-bit targets, as 2048 is the default FRAME_WARN value
for 64-bit platforms, resulting in no -Wframe-larger-than coverage for
this file.

Remove -Wframe-larger-than from CFLAGS_REMOVE_dml2_core_dcn4_calcs.o and
move to $(frame_warn_flag) for CFLAGS_dml2_core_dcn4_calcs.o, as that
accounts for the fact that -Wframe-larger-than may need to be larger
than 2048 in certain situations, such as when the sanitizers are
enabled.

442dd0552c drm/amd/display: Remove unnecessary NULL check in dcn20_set_input_transfer_func
This commit removes an unnecessary NULL check in the
`dcn20_set_input_transfer_func` function in the `dcn20_hwseq.c` file.
The variable `tf` is assigned the address of
`plane_state->in_transfer_func` unconditionally, so it can never be
`NULL`. Therefore, the check `if (tf == NULL)` is unnecessary and has
been removed.

The plane_state->in_transfer_func itself cannot be NULL because it's a
structure, not a pointer. When we do tf =
&plane_state->in_transfer_func;, we're getting the address of that
structure, which will always be valid as long as plane_state itself is
not NULL.

we've already checked if plane_state is NULL with the line if (dpp_base
== NULL || plane_state == NULL) return false;. So, if the code execution
gets to the point where tf = &plane_state->in_transfer_func; is called,
plane_state is guaranteed to be not NULL, and therefore tf will also not
be NULL.

efce15ec3b drm/amd/display: use mpcc_count to log MPC state
According to [1]:
```
DTN only logs 'pipe_count' instances of MPCC. However in some cases
there are different number of MPCC than DPP (pipe_count).
```

As DTN log still relies on pipe_count to print mpcc state, switch to
mpcc_count in all occurrences.

130afc8a88 drm/amd/display: Fix division by zero in setup_dsc_config
When slice_height is 0, the division by slice_height in the calculation
of the number of slices will cause a division by zero driver crash. This
leaves the kernel in a state that requires a reboot. This patch adds a
check to avoid the division by zero.

The stack trace below is for the 6.8.4 Kernel. I reproduced the issue on
a Z16 Gen 2 Lenovo Thinkpad with a Apple Studio Display monitor
connected via Thunderbolt. The amdgpu driver crashed with this exception
when I rebooted the system with the monitor connected.

kernel: ? die (arch/x86/kernel/dumpstack.c:421 arch/x86/kernel/dumpstack.c:434 arch/x86/kernel/dumpstack.c:447)
kernel: ? do_trap (arch/x86/kernel/traps.c:113 arch/x86/kernel/traps.c:154)
kernel: ? setup_dsc_config (drivers/gpu/drm/amd/amdgpu/../display/dc/dsc/dc_dsc.c:1053) amdgpu
kernel: ? do_error_trap (./arch/x86/include/asm/traps.h:58 arch/x86/kernel/traps.c:175)
kernel: ? setup_dsc_config (drivers/gpu/drm/amd/amdgpu/../display/dc/dsc/dc_dsc.c:1053) amdgpu
kernel: ? exc_divide_error (arch/x86/kernel/traps.c:194 (discriminator 2))
kernel: ? setup_dsc_config (drivers/gpu/drm/amd/amdgpu/../display/dc/dsc/dc_dsc.c:1053) amdgpu
kernel: ? asm_exc_divide_error (./arch/x86/include/asm/idtentry.h:548)
kernel: ? setup_dsc_config (drivers/gpu/drm/amd/amdgpu/../display/dc/dsc/dc_dsc.c:1053) amdgpu
kernel: dc_dsc_compute_config (drivers/gpu/drm/amd/amdgpu/../display/dc/dsc/dc_dsc.c:1109) amdgpu

After applying this patch, the driver no longer crashes when the monitor
is connected and the system is rebooted. I believe this is the same
issue reported for 3113.

Driver was passing a wrong command version which to DMCUB which caused

In current implemenation ODM mode is only reset when the last plane is
removed from dc state. For any dc validate we will always remove all
current planes and add new planes. However when switching from no planes
to 1 plane, ODM mode is not reset because no planes get removed. This
has caused an issue where we kept ODM combine when it should have been
remove when a plane is added. The change is to reset ODM mode when

3ca7317809 drm/amd/display: Rebuild test pattern params for DP_TEST_PATTERN_VIDEO_MODE
[Why]
For video mode test pattern (i.e. test pattern disable), the call to
rebuild test pattern params for the pipe is skipped. This causes
dynamic disablement of test pattern to not work, as the
test_pattern_params of the pipe will not be updated and retain the
values of the previously enabled test pattern.

[How]
Rebuild test pattern params even when test pattern is video mode,
allowing the pipe to have updated test_pattern_params values.

[Why]
DTN only logs 'pipe_count' instances of MPCC.
However in some cases there are different number of
MPCC than DPP (pipe_count).

[How]
Add mpcc_count parameter to resource_pool and set it
during pool construction and use it for DTN logging of
MPCC state.

c40845e319 kbuild: make -Woverride-init warnings more consistent
The -Woverride-init warn about code that may be intentional or not,
but the inintentional ones tend to be real bugs, so there is a bit of
disagreement on whether this warning option should be enabled by default
and we have multiple settings in scripts/Makefile.extrawarn as well as
individual subsystems.

Older versions of clang only supported -Wno-initializer-overrides with
the same meaning as gcc's -Woverride-init, though all supported versions
now work with both. Because of this difference, an earlier cleanup of
mine accidentally turned the clang warning off for W=1 builds and only
left it on for W=2, while it's still enabled for gcc with W=1.

There is also one driver that only turns the warning off for newer
versions of gcc but not other compilers, and some but not all the
Makefiles still use a cc-disable-warning conditional that is no
longer needed with supported compilers here.

Address all of the above by removing the special cases for clang
and always turning the warning off unconditionally where it got
in the way, using the syntax that is supported by both compilers.

57b1ce8384 drm/amd/display: fix nonseamless transition from ODM + MPO to ODM + subvp
[why]
 when ODM + MPO is used for all 4 available pipes. Pipe transition will
 be nonseamless. Phantom OTG master pipe reuses the secondary OPP head
 pipe. There is no possible seamless path to transit to the new
 state. The correct logic would be to reuse a secondary DPP pipe as the
 phantom OTG master pipe. This way we are able to first transit the
 minimal transtion state of new and then transit to new state seamlessly.

[Why & How]
There is a corner case where a single PSR panel
fails to enter idle optimizations if the panel
is not flipping (no planes or DPMS_OFF == true).
This is because the panel will not enter PSR if it's
not flipping, but this will prevent the FW idle opt
path from being executed. To handle this case we will
allow entry to idle opt from driver side even when a
PSR panel is connected under the following scenarios:
	1. Only a single PSR panel is connected
	2. PSR panel is not flipping

621cf07a3f drm/amd/display: fix a bug to dereference already freed old current state memory
[why]
During minimal transition commit, the base state could be freed if it is current state.
This is because after committing minimal transition state, the current state will be
swapped to the minimal transition state and the old current state will be released.
the release could cause the old current state's memory to be freed. However dc
will derefernce this memory when release minimal transition state. Therefore, we
need to retain the old current state until we release minimal transition state.

3be6a63e06 drm/amd/display: Enable reallow for idle on DCN35
[Why]
It was previously disabled for stability purposes, but command
submission causes residency issues in IPS video playback.

[How]
Enable the disallow/reallow pattern back. There's additional checks
now in DMCUB that should make this safer stability wise.

93ddf00f87 drm/amd/display: Detect and disallow idle reallow during reentrancy
[Why]
Cursor updates can be preempted by queued flips in some DMs.

The synchronization model causes this to occur within the same thread
at an intermediate level when we insert logs into the OS queue.

Since this occurs on the same thread and we're still holding the lock
(recursively) the cache is coherent.

The exit sequence will run twice since we technically haven't finished
the exit the first time, so we need a way to detect and avoid the
reallow in the middle of this call to prevent the hang on the cursor
update that was preempted.

[How]
Keep a counter that tracks the depth of the exit calls. Do not reallow
until the counter is zero.

b5b6d62515 drm/amd/display: Workaround register access in idle race with cursor
[Why]
Cursor update can be pre-empted by a request for setting target flip
submission.

This causes an issue where we're in the middle of the exit sequence
trying to log to DM, but the pre-emption starts another DMCUB
command submission that requires being out of idle.

The DC lock aqusition can fail, and depending on the DM/OS interface
it's possible that the function inserted into this thread must not fail.

This means that lock aqusition must be skipped and exit *must* occur.

[How]
Modify when we consider idle as active. Consider it exited only once
the exit has fully finished.

Consider it as entered prior to actual notification.

Since we're on the same core/thread the cached values are coherent
and we'll see that we still need to exit. Once the cursor update resumes
it'll continue doing the double exit but this won't cause a functional
issue, just a (potential) redundant operation.

d62d5551dd drm/amd/display: Backup and restore only on full updates
[WHY & HOW]
Since the backup and restore for plane and stream states has
a significant amount of data to copy, we will change the backup
and restore sequence to only take place during full updates.

We will also move the scratch memory to struct dc instead of dc_state
to avoid needing to allocate large amounts of memory every time
we create a new DC state.

2d5bb791e2 drm/amd/display: Implement update_planes_and_stream_v3 sequence
[WHY & HOW]
Update planes and stream version 3 separates FULL and FAST updates
to their own sequences. It aims to clean up frequent checks for
update type resulting unnecessary branching in logic flow. It also
adds a new commit minimal transition sequence, which detects the need
for minimal transition based on the actual comparison of current and
new states instead of "predicting" it based on per feature software
policy, i.e. could_mpcc_tree_change_for_active_pipes.

The new commit minimal transition sequence is made universal to any
power saving features that would use extra free pipes such as Dynamic
ODM/MPC Combine, MPO or SubVp. Therefore there is no longer a need to
specially handle compatibility problems with transitions among those
features as they are now transparent to the new sequence.

63ae548f10 drm/amd/display: Fix potential index out of bounds in color transformation function
Fixes index out of bounds issue in the color transformation function.
The issue could occur when the index 'i' exceeds the number of transfer
function points (TRANSFER_FUNC_POINTS).

The fix adds a check to ensure 'i' is within bounds before accessing the
transfer function points. If 'i' is out of bounds, an error message is
logged and the function returns false to indicate an error.

e2fdd5c525 drm/amd/display: Add left edge pixel for YCbCr422/420 + ODM pipe split
[WHY]
Currently 3-tap chroma subsampling is used for YCbCr422/420. When ODM
pipesplit is used, pixels on the left edge of ODM slices need one extra
pixel from the right edge of the previous slice to calculate the correct
chroma value.

Without this change, the chroma value is slightly different than
expected. This is usually imperceptible visually, but it impacts test
pattern CRCs for compliance test automation.

[HOW]
Update logic to use the register for adding extra left edge pixel for
YCbCr422/420 ODM cases.

[WHY]
When committing an update with ODM combine change when the plane is
removing or already removed, we fail to detect odm change in pipe
update flags. This has caused mismatch between new dc state and the
actual hardware state, because we missed odm programming.

[HOW]
- Detect odm change even for otg master pipe without a plane.
- Update odm config before calling program pipes for pipe with planes.

The commit also updates blank pattern programming when odm is changed
without plane. This is because number of OPP is changed when ODM
combine is changed. Blank pattern is per OPP so we will need to
reprogram OPP based on the new pipe topology.

34b811a281 drm/amd/display: Prevent potential buffer overflow in map_hw_resources
Adds a check in the map_hw_resources function to prevent a potential
buffer overflow. The function was accessing arrays using an index that
could potentially be greater than the size of the arrays, leading to a
buffer overflow.

Adds a check to ensure that the index is within the bounds of the
arrays. If the index is out of bounds, an error message is printed and
break it will continue execution with just ignoring extra data early to
prevent the buffer overflow.

Reported by smatch:

34241dc665 drm/amd/display: reenable windowed mpo odm support on dcn32 and dcn321
[why]
The feature was disabled due to regression found during testing. Now
that all the pending issues are addressed, we are reenabling the power
saving feature again.

The feature optimizes dispclk level when user is using MPO capable
broswers or watching MPO capable videos in windowed mode. The feature
achieves power optimization by utilizing free pipes to process incoming
pixels in parallel. So it reduces max dispclk requirements for each
pipe.

Previously ODM power optimization will be disabled when MPO plane is
present due to technical challeges. This is mainly because ODM divides
pixel workload with respect to stream but MPO plane position and size
are arbitrary with respect to stream. The pixel processing workload of
an MPO plane is not guarenteed to be evenly distributed across DCN pipes.
For example if a plane is moved inside single ODM slice, all the
processing for the plane is distributed to the pipe in the current ODM
slice, while the other ODM slices don't need to process this plane. If
the plane is then moved to the middle crosing two ODM slices, each ODM
slice gets half of the workload. This is especially difficult when the
plane itself has a large source rect which can't be processed by single
DCN pipe. In this case we can't enable ODM power optimization when the
plane is only within one ODM slice.

[how]
To overcome the challeges, new pipe resource management is in place to
make sure a plane is validated with ODM power optimization support if
it can be validated regardless of its position and the same pipe
topology can be used regardless of the plane's position. When the plane
is moved outside current ODM slice, we will set recout to 0 so the pipe
can be idling without the need to update pipe topology. When the user
resizes a plane, it may result in downscaling ratio changes. When the
downscaling ratio is above single pipe's threshold, we will seamlessly
exit ODM power optimization and applies MPC combine to support the plane.
when downscaling ratio becomes smaller, we will seamlessly enter ODM
power optimization again. All these pipe transitions happen
automatically and quietly when the conditions are met without any visual
impacts to the user.

To make this change we add pointers in the plane state, stream, and

1d55183c2c drm/amd/display: Fix potential null pointer dereference in dc_dmub_srv
Fixes potential null pointer dereference warnings in the
dc_dmub_srv_cmd_list_queue_execute() and dc_dmub_srv_is_hw_pwr_up()
functions.

In both functions, the 'dc_dmub_srv' variable was being dereferenced
before it was checked for null. This could lead to a null pointer
dereference if 'dc_dmub_srv' is null. The fix is to check if
'dc_dmub_srv' is null before dereferencing it.

Thus moving the null checks for 'dc_dmub_srv' to the beginning of the
functions to ensure that 'dc_dmub_srv' is not null when it is
dereferenced.

Found by smatch & thus fixing the below:
drivers/gpu/drm/amd/amdgpu/../display/dc/dc_dmub_srv.c:133 dc_dmub_srv_cmd_list_queue_execute() warn: variable dereferenced before check 'dc_dmub_srv' (see line 128)

Need to fix some broken logic and sequencing in initial commit

[HOW]
Fix logic handling override deprogramming when exiting SQ128.

Don't exit early from dp_set_hw_lane_settings for DP2/FIXED_VS case.

Move LTTPR 128b/132b check out of  requires_hwss and check during
runtime, as LTTPR caps are not populated on initial call.

Add pending_test_pattern to link state to allow HWSS to set FFE overrides
on retimer TX and/or skip setting APU TX FFE depending on requested pattern.

Use updated clock source for SQ128 override sequence.

Skip HW FFE preset programming when performing test pattern overrides.

9ab1a996dc drm/amd/display: Fix possible buffer overflow in 'find_dcfclk_for_voltage()'
when 'find_dcfclk_for_voltage()' function is looping over
VG_NUM_SOC_VOLTAGE_LEVELS (which is 8), but the size of the DcfClocks
array is VG_NUM_DCFCLK_DPM_LEVELS (which is 7).

When the loop variable i reaches 7, the function tries to access
clock_table->DcfClocks[7]. However, since the size of the DcfClocks
array is 7, the valid indices are 0 to 6. Index 7 is beyond the size of
the array, leading to a buffer overflow.

Reported by smatch & thus fixing the below:

15dba12c56 drm/amd/display: Implement bounds check for stream encoder creation in DCN301
'stream_enc_regs' array is an array of dcn10_stream_enc_registers
structures. The array is initialized with four elements, corresponding
to the four calls to stream_enc_regs() in the array initializer. This
means that valid indices for this array are 0, 1, 2, and 3.

The error message 'stream_enc_regs' 4 <= 5 below, is indicating that
there is an attempt to access this array with an index of 5, which is
out of bounds. This could lead to undefined behavior

Here, eng_id is used as an index to access the stream_enc_regs array. If
eng_id is 5, this would result in an out-of-bounds access on the
stream_enc_regs array.

Thus fixing Buffer overflow error in dcn301_stream_encoder_create
reported by Smatch:

6a068e64fb drm/amd/display: Update phantom pipe enable / disable sequence
Previously we would call apply_ctx_to_hw to enable and disable
phantom pipes. However, apply_ctx_to_hw can potentially update
non-phantom pipes as well which is undesired. Instead of calling
apply_ctx_to_hw as a whole, call the relevant helpers for each
phantom pipe when enabling / disabling which will avoid us modifying
hardware state for non-phantom pipes unknowingly.

The use case is for an FRL display where FRL_Update is requested
by the display. In this case link_state_valid flag is cleared in
a passive callback thread and should be handled in the next stream /
link update. However, due to the call to apply_ctx_to_hw for the
phantom pipes during a flip, the main pipes were modified outside
of the desired sequence (driver does not handle link_state_valid = 0
on flips).

288c0254a0 drm/amd/display: Add left edge pixel for YCbCr422/420 + ODM pipe split
[Why]
Currently 3-tap chroma subsampling is used for YCbCr422/420. When ODM
pipesplit is used, pixels on the left edge of ODM slices need one extra
pixel from the right edge of the previous slice to calculate the correct
chroma value.

Without this change, the chroma value is slightly different than
expected. This is usually imperceptible visually, but it impacts test
pattern CRCs for compliance test automation.

[How]
Update logic to use the register for adding extra left edge pixel for
YCbCr422/420 ODM cases.

0a5fd7811a drm/amd/display: set odm_combine_policy based on context in dcn32 resource
[why]
When populating dml pipes, odm combine policy should be assigned based
on the pipe topology of the context passed in. DML pipes could be
repopulated multiple times during single validate bandwidth attempt. We
need to make sure that whenever we repopulate the dml pipes it is always
aligned with the updated context. There is a case where DML pipes get
repopulated during FPO optimization after ODM combine policy is changed.
Since in the current code we reinitlaize ODM combine policy, even though
the current context has ODM combine enabled, we overwrite it despite the
pipes are already split. This causes DML to think that MPC combine is
used so we mistakenly enable MPC combine because we apply pipe split
with ODM combine policy reset. This issue doesn't impact non windowed
MPO with ODM case because the legacy policy has restricted use cases. We
don't encounter the case where both ODM and FPO optimizations are
enabled together. So we decide to leave it as is because it is about to
be replaced anyway.

e3854253a5 drm/amd/display: Fix buffer overflow in 'get_host_router_total_dp_tunnel_bw()'
The error message buffer overflow 'dc->links' 12 <= 12 suggests that the
code is trying to access an element of the dc->links array that is
beyond its bounds. In C, arrays are zero-indexed, so an array with 12
elements has valid indices from 0 to 11. Trying to access dc->links[12]
would be an attempt to access the 13th element of a 12-element array,
which is a buffer overflow.

To fix this, ensure that the loop does not go beyond the last valid
index when accessing dc->links[i + 1] by subtracting 1 from the loop
condition.

This would ensure that i + 1 is always a valid index in the array.

Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/dc/link/protocols/link_dp_dpia_bw.c:208 get_host_router_total_dp_tunnel_bw() error: buffer overflow 'dc->links' 12 <= 12

In current code, we recognize a pipe as a phantom pipe if it references
the same phantom stream. However it can also a phantom split pipe.
If the phantom split pipe has a smaller pipe index than the phantom pipe
we will mistakenly use the phantom split pipe as the phantom pipe. This
causes an incorrect subvp configuration where the first half of the
screen is flashing solid white image.

e432f14a42 drm/amd/display: hook up DCN20 color blocks data to DTN log
Color caps changed between HW versions, which caused the DCN10 color
state sections in the DTN log to no longer match DCN2+ state. Create a
color state log specific to DCN2.0 and hook it up to DCN2 family
drivers. Instead of reading gamut remap reg values, display gamut remap

f980579c29 drm/amd/display: Replay + IPS + ABM in Full Screen VPB
[Why]
Because ABM will wait VStart to start getting histogram data,
 it will cause we can't enter IPS while full screnn video playing.

[How]
Modify the panel refresh rate to the maximun multiple of current
 refresh rate.

4516a79302 drm/amd/display: turn off windowed Mpo ODM feature for dcn321
[why]
It has been found a regression caused by enabling this feature during ODM to
MPC combine switch when user is resizing video window. The transition is
only needed when the feature is enabled. During the transition driver will
temporary switch to use max dppclk level through SMU set hard min interface.
The interface times out and fail to configure the max dpp clock level, which caused
system issue as the desired clock can't be set. We will continue investigating
the issue and root cause the issue where max dppclk level can't be reached.
But for now we have to disable this feature as this feature will cause us to hit this
problem in common use cases during video playback unfortunately. The issue
is dcn321 specific so it won't impact other dcn revisions.
