c83b9d6029 drm/amd/display: make variables static
As "dcn3_1_soc", "dcn3_15_soc", and "dcn3_16_soc" are not used outside
of their corresponding "dcn3*_fpu.c", make them static and remove their
extern declaration.

41ead3e0cd drm/amd/display: remove DML Makefile duplicate lines
There are two identical CFLAGS entries for "display_mode_vba_20.o", so
remove one of them. Also, as there's already an entry for
"display_mode_lib.o" CFLAGS, regardless of CONFIG_DRM_AMD_DC_DCN being
defined or not, remove the one entry between CONFIG_DRM_AMD_DC_DCN ifdef
guards.

798cd57cd5 drm/amd/display: restore code for plane with no modifiers
When this file was split in commit 5d945cbcd4 ("drm/amd/display:
Create a file dedicated to planes") this chunk seemed to get dropped.

Linus noticed on this rx580 and I've reproduced on FIJI which makes
sense as these are pre-modifier GPUs.

With this applied, I get gdm back.

64f991590f drm/amd/display: Fix a compilation failure on PowerPC caused by FPU code
We got a report from Stephen/Michael that the PowerPC build was failing
with the following error:

ld: drivers/gpu/drm/amd/display/dc/dml/display_mode_lib.o uses hard float, drivers/gpu/drm/amd/display/dc/dcn30/dcn30_optc.o uses soft float
ld: failed to merge target specific data of file drivers/gpu/drm/amd/display/dc/dcn30/dcn30_optc.o

This error happened because of the function optc3_set_vrr_m_const. This
function expects a double as a parameter in a code that is not allowed
to have FPU operations. After further investigation, it became clear
that optc3_set_vrr_m_const was never invoked, so we can safely drop this
function and fix the ld issue.

With struct drm_plane_funcs removed from drm_plane_helper.h, also remove
the include statements. It only needs linux/types.h for uint32_t and a

c653c59178 drm/amdgpu: Re-enable DCN for 64-bit powerpc
Commit d11219ad53 ("amdgpu: disable powerpc support for the newer
display engine") disabled the DCN driver for all of powerpc due to
unresolved build failures with some compilers.

Further digging shows that the build failures only occur with compilers
that default to 64-bit long double.

Both the ppc64 and ppc64le ABIs define long double to be 128-bits, but
there are compilers in the wild that default to 64-bits. The compilers
provided by the major distros (Fedora, Ubuntu) default to 128-bits and
are not affected by the build failure.

There is a compiler flag to force 128-bit long double, which may be the
correct long term fix, but as an interim fix only allow building the DCN
driver if long double is 128-bits by default.

The bisection in commit d11219ad53 must have gone off the rails at
some point, the build failure occurs all the way back to the original
commit that enabled DCN support on powerpc, at least with some
toolchains.

c13423c63f drm/amd/display: Copy crc_skip_count when duplicating CRTC state
[Why]

crc_skip_count is used to track how many frames to skip to allow the OTG
CRC engine to "warm up" before it outputs correct CRC values.
Experimentally, this seems to be 2 frames.

When duplicating CRTC states, this value was not copied to the
duplicated state. Therefore, when this state is committed, we will
needlessly wait 2 frames before outputing CRC values. Even if the CRC
engine is already warmed up.

[How]

Copy the crc_skip_count as part of dm_crtc_duplicate_state.

f4b4e41a2e drm/amd/display: Update DML logic for unbounded req handling
[why]
Unbounded request logic in resource/DML has some issues where unbounded
request is being enabled incorrectly. SW today enables unbounded request
unconditionally in hardware, on the assumption that HW can always
support it in single pipe scenarios.

This worked until now because the same assumption is made in DML. A new
DML update is needed to fix a bug, where there are single pipe scenarios
where unbounded cannot be enabled, and this change in DML needs to be
ported in, and dcn32 resource logic fixed.

[how]
First, dcn32_resource should program unbounded req in HW according to
unbounded req enablement output from DML, as opposed to DML input.

Second, port in DML update which disables unbounded req in some
scenarios to fix an issue with poor stutter performance

e6c64182ed drm/amd/display: remove number of DSC slices override in DML
[why]
Number of DSC slices is an input to DML with high dependency
on display specific capability. This isn't something DML can decide
on its own. DML has to use the original number of DSC slices input
to DML during validation without modification. Otherwise the
computed DSC delay will not reflect the current configuration
and therefore causes validation failures.

[how]
Remove DML override for number of DSC slices parameter.

473683a034 drm/amd/display: Create a file dedicated for CRTC
[Why]
The amdgpu_dm file contains most of the code that works as an interface
between DRM API and DC. As a result, this file becomes very large since
it comprises multiple abstractions such as CRTC manipulation.

[How]
This commit extracts the CRTC code to its specific file named
amdgpu_dm_crtc. This change does not change anything inside the
functions; the only exception is converting some static functions to a
global function.

8a9899c95d drm/amd/display: Support vertical interrupt 0 for all dcn ASIC
[Why]
When CONFIG_DRM_AMD_SECURE_DISPLAY is enabled, it will try
to register vertical interrupt 0 for specific task.

Currently, only dcn10 have defined relevant info for vertical interrupt
0. If we enable CONFIG_DRM_AMD_SECURE_DISPLAY for other dcn ASIC, will
get DC_IRQ_SOURCE_INVALID while calling dc_interrupt_to_irq_source() and
cause pointer errors.

[How]
Add support of vertical interrupt 0 for all dcn ASIC.

3876a8b5e2 drm/amd/display: Enable building new display engine with KCOV enabled
The new display engine uses floating point math, which is not supported
by KCOV. Commit 9d1d02ff36 ("drm/amd/display: Don't build DCN1 when kcov
is enabled") tried to work around the problem by disabling
CONFIG_DRM_AMD_DC_DCN if KCOV_INSTRUMENT_ALL and KCOV_ENABLE_COMPARISONS
are enabled. The result is that KCOV can not be enabled on systems which
require this display engine. A much simpler and less invasive solution is
to disable KCOV selectively when compiling the display enagine while
keeping it enabled for the rest of the kernel.

d11219ad53 amdgpu: disable powerpc support for the newer display engine
The DRM_AMD_DC_DCN display engine support (Raven, Navi, and newer) has
not been building cleanly on powerpc and causes link errors due to
mixing hard- and soft-float object files:

  powerpc64-linux-ld: drivers/gpu/drm/amd/amdgpu/../display/dc/dml/display_mode_lib.o uses hard float, drivers/gpu/drm/amd/amdgpu/../display/dc/dcn31/dcn31_resource.o uses soft float
  powerpc64-linux-ld: failed to merge target specific data of file drivers/gpu/drm/amd/amdgpu/../display/dc/dcn31/dcn31_resource.o
  [..]

and while patches are floating around, it's not exactly obvious what is
going on.

The problem bisects to commit 41b7a347bf ("powerpc: Book3S 64-bit
outline-only KASAN support") but that is probably more about changing
config variables than the fundamental cause.

Despite the bisection result, a more directly related commit seems to be
26f4712aed ("drm/amd/display: move FPU related code from dcn31 to
dml/dcn31 folder").  It's probably a combination of the two.

This has been going on since the merge window, without any final word.
So instead of blindly applying patches that may or may not be the right
thing, let's disable this for now.

As Michael Ellerman says:
 "IIUIC this code was never enabled on ppc before, so disabling it seems
  like a reasonable fix to get the build clean"

and once we have more actual feedback (and find any potential users) we
can always re-enable it with the patch that fixes the issues and
back-port as necessary.

on CIK GPUs") for DCE-8. So far >= DCE-11.2 was considered ok, but now I
found out that on DCE-11.2 it causes dithering when there shouldn't be
any, so identity pixel passthrough with identity gamma LUTs doesn't work
when it should. This breaks various important neuroscience applications,
as reported to me by scientific users of Polaris cards under Ubuntu 22.04
with Linux 5.15, and confirmed by testing it myself on DCE-11.2.

Lets only use depth 36 for DCN engines, where my testing showed that it
is both necessary for high color precision output, e.g., RGBA16 fb's,
and not harmful, as far as more than one year in real-world use showed.

DCE engines seem to work fine for high precision output at 30 bpp, so
this ("famous last words") depth 30 should hopefully fix all known problems
without introducing new ones.

Successfully retested on DCE-11.2 Polaris and DCN-1.0 Raven Ridge on
top of Linux 5.19.0-rc2 + drm-next.

652284d6db drm/amd/display: Fix lag when moving windowed MPO across display using ODM 2:1 combine
[Why]
With single display odm 2:1 policy, when moving windowed MPO across
 the display, we experience a momentary lag when we move between the
 centre of the display and the right half of the display.  This is
 caused by the MPO pipe being reallocated when it crosses this
 boundary

[How]
Handle two cases:
1. if the head pipe has a MPO pipe already allocated in the old
 context, then use that pipe if it is available in the current
 context
2. if the head pipe is on the left side, check the right side to
 see if it has a MPO pipe already allocated.  If so, don't use
 that pipe if it is selected as the idle pipe in the current
 context
Add new function pointer called .acquire_idle_pipe_for_head_pipe
 that will pass in the head pipe and handle case 1
Add find_idle_secondary_pipe_check_mpo() to handle case 2
 if we don't hit case 1.

In dc_add_plane_to_context(), start with head pipe and check
 case 1 and 2 in call acquire_free_pipe_for_head().
If we are on the right side of the display, check case 1
 again by passing in right side pipe as the new head in
 call acquire_free_pipe_for_head().

e5028e9fd3 drm/amd/display: Add DCN reg offsets to DC
[Why&How]
Add a field to store the DCN IP offset for use with runtime offset
calculation

This offset is indexed using reg*_BASE_IDX for the corresponding
group of registers. For example, address of DIG_BE_CNTL instance 0 is
calculated like: dcn_reg_offsets[regDIG0_DIG_BE_CNTL_BASE_IDX] +
regDIG0_DIG_BE_CNTL.

{dcn,nbio}_reg_offsets are used only for the ASICs for which runtime
initializaion of offsets are enabled through the modified SR* macros
that contain an additional REG_STRUCT element in the macro definition.

DCN3.5+ will fail dc_create() if {dcn,nbio}_reg_offsets are null. They
are applicable starting with DCN32/321 and are not used for ASICs
upstreamed before them. ASICs before DCN32/321 will not contain any
computation that involves {dcn,nbio}_reg_offsets. For them, the
address/offset computation is done during compile time.

This is evident from the BASE_INNER definition for compile time vs run
time initialization:

Compile time init: #define BASE_INNER(seg) DCN_BASE__INST0_SEG ## seg
Run time init:     #define BASE_INNER(seg) ctx->dcn_reg_offsets[seg]

BASE_INNER macro is local to each dcnxx_resource.c and hence different
ASICs can have either runtime or compile time initialization of offsets.

The computation of offset is done for registers all at once during
driver load and hence it does not introduce any performance overhead
during normal operation.

1f969d28cd drm/amd/display: update DML1 logic for unbounded req handling
[why]
Unbounded request logic in resource/DML has some issues where
unbounded request is being enabled incorrectly.  SW today enables
unbounded request unconditionally in hardware, on the assumption
that HW can always support it in single pipe scenarios.

This worked until now because the same assumption is made in DML.
A new DML update is needed to fix a bug, where there are single
pipe scenarios where unbounded cannot be enabled, and this change
in DML needs to be ported in, and dcn32 resource logic fixed.

[how]
First, dcn32_resource should program unbounded req in HW according
to unbounded req enablement output from DML, as opposed to DML input

Second, port in DML1 update which disables unbounded req in some
scenarios to fix an issue with poor stutter performance

017860c909 drm/amd/display: make enable link independent from verified link caps
[why]
Ideally link capability should be independent from the link
configuration that we decide to use in enable link. Otherwise if link
capability is changed after validation has completed, we could end up
enabling a link configuration with invalid configuration. This would
lead to over link bandwidth subscription or in the extreme case
causes us to enable HPO link to a DIO stream.

[how]
Add a new struct in pipe ctx called link config. This structure will
contain link configuration to enable a link. It will be populated
during map pool resources after we validate link bandwidth. Remove
the reference of verified link cap during enable link process and
use link config in pipe ctx instead.

[Description]
Exit SubVP if MPO is in use since SubVP + MPO together is not supported.
- Don't add SubVP at validation time if we see MPO is in use

Issues fixed in the SubVP / MPO transition:
1. Enable phantom pipes in post unlock function to prevent underflow
when an active pipe is being transitioned to be a phantom pipe (VTG
updates take place right away). Also must wait for VUPDATE of the main
pipe to complete first

2. Don't wait for MPCC idle when transitioning a phantom pipe to an
actual pipe. MPCC_STATUS is never asserted due to OTG being off for
phantom pipes

3. When transitioning an active pipe to phantom, program DET right away
(same as disabling the pipe) or the DET update will only take when
the phantom pipe is enabled which can cause DET allocation errors.

4. For K1/K2 programming of phantom pipes, use same settings as the
main pipe. Also don't program K1 / K2 = 0xF ever since the field is only
1 / 2 bits wide.

9a23fcf79d drm/amd/display: Enable ODM combine default policy
[Why&How]
Output Data Mapping is a power saving feature that allows us to run at
reduced DPP and DISP clocks compared to what could be achieved with a
single pipe.

Set the default policy for single display use case to use 2 to 1 ODM combine.
The options are queried by DC and appropriate register programming sequence
is initiated to enable this feature.

22676bc500 drm/amd/display: Fix dmub soft hang for PSR 1
[Why]
Unexpected change of aux hw mapping causes dmub soft hang when
initiate aux transation at wrong aux channel.

ddc_channel stands for hw dp aux index which is from vbios,
but link_index is pure software concept for link count depending on which link
is probed first. They are not interchangeable.

dmub aux transaction could pass if happens eDP link_index gets
the same value as vbios ddc_channel, e.g., ddc_channel = 1, link_index = 1
if they gets different, e.g., ddc_channel = 2, link_index = 0, overwrite
ddc_channel with link_index will have wrong ddc channel being used for aux
transaction in dmub PSR, cause aux transaction soft hang.

[How]
ddc_channel mapping to each link is determined by vbios and further
parsed in dc. Such info. should not be touched in any kind, otherwise
the mapping is screwed up leading to aux transaction timeout.

6366b00346 drm/amd/display: Maintain consistent mode of operation during encoder assignment
[Why]
While applying a state to hardware, there is a transition period where
the back-end is reset using the old state; then enabled using the new
state.

Generally, the link encoder configuration module queries
stream-to-encoder assignments in either the new or old state based on a
mode variable. During the transition there is a need to query both
states, however toggling this mode variable can lead to incorrect
programming of encoders.

[How]
- Add new function to explicity query stream-to-encoder assignment
in the current state rather than intermittently switch the mode
of operation of the link encoder assignment module.
- Add additional checks for encoder assignment defects.
- Explicitly reset the mode of operation if application of state
to hardware ends prematurely.

97ca308925 drm/amd/display: Add minimal pipe split transition state
[WHY?]
When adding/removing a plane to some configurations, unsupported pipe
programming can occur when moving to a new plane.  Such cases include pipe
split on multi-display, with MPO, and/or ODM.

[HOW?]
Add a safe transistion state that minimizes pipe usage before programming
new configuration. When adding a plane, the current state has the least
pipes required so it is applied without splitting.  This must be applied
prior to updating the plane_state for seamless transition.  When removing a
plane, the new state has the least pieps required so it is applied without
splitting.

48e03843f9 drm/amd/display: Fix stream->link_enc unassigned during stream removal
[Why]
Found when running igt@kms_atomic.

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

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

Fixes global state from being modified while unlocked.

88ef4c5bb3 drm/amd/display: Apply ODM 2:1 policy for single display configuration
[Why]
Most of the time, a single display uses the ODM combine. When using
multi-display, we use ODM combine only if it is necessary. These cases
are not flexible enough for us, and we can improve them to take
advantage of our hardware. We want to have more control over the ODM
policy.

[How]
This commit add a new debug flag named
enable_single_display_2to1_odm_policy to control the ODM policy and
another flag named enable_dp_dig_pixel_rate_div_policy to fine control
the ODM combine. This is possible by adding a new "pipe.dest" parameter
that can be set to ODM 2:1 combined if we use a single display. For
dynamic ODM combine, when using DP-DIG, DCN applies K2=2 settings for
ODM combine. Note that this feature affects the following registers:

- timing.pix_clk_100khz -> DP_VID_M, DP_VID_N
- requested_pix_clk_100hz -> DP_DTOn_PHASE
- OTGn_PIXEL_RATE_DIVK2
- DP_PIXEL_PER_CYCLE_PROCESSING_MODE
- DIG_FIFO_OUTPUT_PIXEL_MODE
- DP_VID_N_MUL

366e817e83 Revert "drm/amd/display: ignore modifiers when checking for format support"
This reverts commit 5089c4a8eb.

This breaks validation and enumeration of display capable modifiers.

The early return true means the rest of the validation code never gets
executed, and we need that to enumerate the right modifiers to userspace
for the format.

The modifiers that are in the initial list generated for a plane are the
superset for all formats and we need the proper checks in this function
to filter some of them out for formats with which they're invalid to be
used.

Furthermore, the safety contract here is that we validate the incoming
modifiers to ensure the kernel can handle them and the display hardware
can handle them. This includes e.g. rejecting multi-plane images with DCC.

Note that the legacy swizzle mechanism allows encoding more swizzles, and
at fb creation time we convert them to modifiers and reject those with
no corresponding modifiers. If we are seeing rejections I'm happy to
help define modifiers that correspond to those, or if absolutely needed
implement a fallback path to allow for less strict validation of the
legacy path.

However, I'd like to revert this patch, since any of these is going to
be a significant rework of the patch, and I'd rather not the regression
gets into a release or forgotten in the meantime.

aeb73c608c drm/amd/display: Implement a pme workaround function
[Why]
For DCN32 we do not have a pme workaround function defined that sends a
BacoAudio message. Default code had uses the DCN30 function for pme
workaround. PMFW headers are inconsistent with their message ID
definitions which cause ID's to clash leading to inconsistent system
behaviour. There is a clash with FCLK message due to inconsitent PMFW
headers.

[How]
Implement a new BacoAudio function to workaround the problem of
inconsistent PMFW headers in order to avoid BacoAudio message clasing
with FCLK Enable message.

[why]
Only on VG, if external display is disconnected during S3 suspend, the
internal panel doesn't light up on resume because we set the power state
using an unsupported DPCD register SET_POWER.  To check the register is
supported, we need to check SET_POWER_CAPABLE first which is
eDP-specific DPCD register field.

Check the SET_POWER_CAPABLE register field and decide the control of the
eDP power state based on the read register value.

84a8b39082 drm/amd/display: Release remote dc_sink under mst scenario
[Why]
Observe that we have several problems while releasing remote dc_sink
under mst cases.

- When unplug mst branch device from the source, we now try to free all
  remote dc_sinks in dm_helpers_dp_mst_stop_top_mgr(). However, there are
  bugs while we're releasing dc_sinks here. First of all,
  link->remote_sinks[] array get shuffled within
  dc_link_remove_remote_sink(). As the result, increasing the array index
  within the releasing loop is wrong. Secondly, it tries to call
  dc_sink_release() to release the dc_sink of the same aconnector every
  time in the loop. Which can't release dc_sink of all aconnector in the
  mst topology.
- There is no code path for us to release remote dc_sink for disconnected
  sst monitor which unplug event is notified by CSN sideband message. Which
  means we'll use stale dc_sink data to represent later on connected
  monitor. Also, has chance to break the maximum remote dc_sink number
  constraint.

[How]
Distinguish unplug event of mst scenario into 2 cases.

* Unplug sst/legacy stream sink off the mst topology
- Release related remote dc_sink in detec_ctx().

* Unplug mst branch device off the mst topology
- Release related remote dc_sink in early_unregister()

052eaf6af8 drm/amd/display: Revert "drm/amd/display: turn DPMS off on connector unplug"
This reverts commit 3c4d55c9b9.

Revert the commit because:
- It's incomplete of the function dm_set_dpms_off() for mst case.  For
  stream sinks whithin the same mst topology, they share the same dc_link.
  dm_set_dpms_off() tries to update one mst stream only which is
  incomplete.
- Setting dpms off should be triggered by usermode. Besdies, it seems
  usermode does release relevant resource for mst & non-mst case when
  unplug connecotr now.

10a3622615 drm/amd/display: Revert "drm/amd/display: Add flag to detect dpms force off during HPD"
This reverts commit 035f54969b.

The reverted commit was trying to fix side effect brought by
commit 3c4d55c9b9 ("drm/amd/display: turn DPMS off on connector unplug")

However,
* This reverted commit will have mst case never call dm_set_dpms_off()
  which conflicts the idea of original commit 3c4d55c9b9 ("drm/amd/display: turn DPMS off on connector unplug")
  That's due to dm_crtc_state is always null since the input parameter
  aconnector is the root device (source) of mst topology.  It's not an
  end stream sink within the mst topology.
* Setting dpms off should be triggered by usermode. Besdies, it seems
  usermode does release relevant resource for mst & non-mst case when
  unplug connecotr now. Which means we no longer need both commits now:
  commit 3c4d55c9b9 ("drm/amd/display: turn DPMS off on connector unplug")
  commit 035f54969b ("drm/amd/display: Add flag to detect dpms force off during HPD")

4e1db0119c Revert "drm/amdgpu/display: Protect some functions with CONFIG_DRM_AMD_DC_DCN"

without CONFIG_DRM_AMD_DC_DCN.
