[Why]
On secondary display hotplug we switch primary
stream from ODM2to1 to ODMBypass mode. Current
logic will trigger disabling front end for this
stream.
[How]
We need to check if prev_odm_pipe is equal to NULL
in order to disable dangling planes in this scenario.

[Why]
Pipes get merged in preparation for SubVP but if they don't get used, and
are in ODM or some other multi pipe config, it would calculate the
voltage level with a viewport of just one pipe from when they were split
resulting in too low of a voltage level.
[How]
Made it so that the viewport and other timing settings get rebuilt and re-
initialized after the pipe merge, before calculating the voltage level so it
would calculate it correctly.

[WHY]
SmartAccess Graphics 1.5 (a.k.a SmartMux 1.5)
requires seamless switching between GPUs
with DSC enabled.
[HOW]
Moved DSC programming to
apply_single_control_ctx_to_hw before the stream
enablement logic to ensure the CRC checker provides valid
values for non-black frames
allowing the system to come out of forced PSR on
d2i.
Added additional logic to both generate a black
frame through setVisibility calls and keep track
of the CRCs values for this black frame when
coming out of forced PSR.
Updating logic for DalRegKey_DisableDSC to disable
DSC on EDP and all ports for systems.

Before this commit when we want userspace to use the acpi_video backlight
device we register both the GPU's native backlight device and acpi_video's
firmware acpi_video# backlight device. This relies on userspace preferring
firmware type backlight devices over native ones.
Registering 2 backlight devices for a single display really is
undesirable, don't register the GPU's native backlight device when
another backlight device should be used.
Changes in v2:
- To avoid linker errors when amdgpu is builtin and video_detect.c is in
a module, select ACPI_VIDEO and its deps if ACPI is enabled.
When ACPI is disabled, ACPI_VIDEO is also always disabled, ensuring
the stubs from acpi/video.h will be used.
Changes in v3:
- Use drm_info(drm_dev, "...") to log messages
- ACPI_VIDEO can now be enabled on non X86 too,
adjust the Kconfig changes to match this.

Now that we've finally gotten rid of the non-atomic MST users leftover in
the kernel, we can finally get rid of all of the legacy payload code we
have and move as much as possible into the MST atomic state structs. The
main purpose of this is to make the MST code a lot less confusing to work
on, as there's a lot of duplicated logic that doesn't really need to be
here. As well, this should make introducing features like fallback link
retraining and DSC support far easier.
Since the old payload code was pretty gnarly and there's a Lot of changes
here, I expect this might be a bit difficult to review. So to make things
as easy as possible for reviewers, I'll sum up how both the old and new
code worked here (it took me a while to figure this out too!).
The old MST code basically worked by maintaining two different payload
tables - proposed_vcpis, and payloads. proposed_vcpis would hold the
modified payload we wanted to push to the topology, while payloads held the
payload table that was currently programmed in hardware. Modifications to
proposed_vcpis would be handled through drm_dp_allocate_vcpi(),
drm_dp_mst_deallocate_vcpi(), and drm_dp_mst_reset_vcpi_slots(). Then, they
would be pushed via drm_dp_mst_update_payload_step1() and
drm_dp_mst_update_payload_step2().
Furthermore, it's important to note how adding and removing VC payloads
actually worked with drm_dp_mst_update_payload_step1(). When a VC payload
is removed from the VC table, all VC payloads which come after the removed
VC payload's slots must have their time slots shifted towards the start of
the table. The old code handles this by looping through the entire payload
table and recomputing the start slot for every payload in the topology from
scratch. While very much overkill, this ends up doing the right thing
because we always order the VCPIs for payloads from first to last starting
timeslot.
It's important to also note that drm_dp_mst_update_payload_step2() isn't
actually limited to updating a single payload - the driver can use it to
queue up multiple payload changes so that as many of them can be sent as
possible before waiting for the ACT. This is -technically- not against
spec, but as Wayne Lin has pointed out it's not consistently implemented
correctly in hubs - so it might as well be.
drm_dp_mst_update_payload_step2() is pretty self explanatory and basically
the same between the old and new code, save for the fact we don't have a
second step for deleting payloads anymore -and thus rename it to
drm_dp_mst_add_payload_step2().
The new payload code stores all of the current payload info within the MST
atomic state and computes as much of the state as possible ahead of time.
This has the one exception of the starting timeslots for payloads, which
can't be determined at atomic check time since the starting time slots will
vary depending on what order CRTCs are enabled in the atomic state - which
varies from driver to driver. These are still stored in the atomic MST
state, but are only copied from the old MST state during atomic commit
time. Likewise, this is when new start slots are determined.
Adding/removing payloads now works much more closely to how things are
described in the spec. When we delete a payload, we loop through the
current list of payloads and update the start slots for any payloads whose
time slots came after the payload we just deleted. Determining the starting
time slots for new payloads being added is done by simply keeping track of
where the end of the VC table is in
drm_dp_mst_topology_mgr->next_start_slot. Additionally, it's worth noting
that we no longer have a single update_payload() function. Instead, we now
have drm_dp_mst_add_payload_step1|2() and drm_dp_mst_remove_payload(). As
such, it's now left it up to the driver to figure out when to add or remove
payloads. The driver already knows when it's disabling/enabling CRTCs, so
it also already knows when payloads should be added or removed.
Changes since v1:
* Refactor around all of the completely dead code changes that are
happening in amdgpu for some reason when they really shouldn't even be
there in the first place… :\
* Remove mention of sending one ACT per series of payload updates. As Wayne
Lin pointed out, there are apparently hubs on the market that don't work
correctly with this scheme and require a separate ACT per payload update.
* Fix accidental drop of mst_mgr.lock - Wayne Lin
* Remove mentions of allowing multiple ACT updates per payload change,
mention that this is a result of vendors not consistently supporting this
part of the spec and requiring a unique ACT for each payload change.
* Get rid of reference to drm_dp_mst_port in DC - turns out I just got
myself confused by DC and we don't actually need this.
Changes since v2:
* Get rid of fix for not sending payload deallocations if ddps=0 and just
go back to wayne's fix

There's another kind of situation where we could potentially race with
nonblocking modesets and MST, especially if we were to only use the locking
provided by atomic modesetting:
* Display 1 begins as enabled on DP-1 in SST mode
* Display 1 switches to MST mode, exposes one sink in MST mode
* Userspace does non-blocking modeset to disable the SST display
* Userspace does non-blocking modeset to enable the MST display with a
different CRTC, but the SST display hasn't been fully taken down yet
* Execution order between the last two commits isn't guaranteed since they
share no drm resources
We can fix this however, by ensuring that we always pull in the atomic
topology state whenever a connector capable of driving an MST display
performs its atomic check - and then tracking CRTC commits happening on the
SST connector in the MST topology state. So, let's add some simple helpers
for doing that and hook them up in various drivers.

I'm not sure why, but at the time I originally wrote the find/release time
slot helpers I thought we should avoid keeping modeset tracking out of the
MST helpers. In retrospect though there's no actual good reason to do
this, and the logic has ended up being identical across all the drivers
using the helpers. Also, it needs to be fixed anyway so we don't break
things when going atomic-only with MST.
So, let's just move this code into drm_dp_atomic_release_time_slots() and
stop open coding it.

As Daniel Vetter pointed out, if we only use the atomic modesetting locks
with MST it's technically possible for a driver with non-blocking modesets
to race when it comes to MST displays - as we make the mistake of not doing
our own CRTC commit tracking in the topology_state object.
This could potentially cause problems if something like this happens:
* User starts non-blocking commit to disable CRTC-1 on MST topology 1
* User starts non-blocking commit to enable CRTC-2 on MST topology 1
There's no guarantee here that the commit for disabling CRTC-2 will only
occur after CRTC-1 has finished, since neither commit shares a CRTC - only
the private modesetting object for MST. Keep in mind this likely isn't a
problem for blocking modesets, only non-blocking.
So, begin fixing this by keeping track of which CRTCs on a topology have
changed by keeping track of which CRTCs we release or allocate timeslots
on. As well, add some helpers for:
* Setting up the drm_crtc_commit structs in the ->commit_setup hook
* Waiting for any CRTC dependencies from the previous topology state
v2:
* Use drm_dp_mst_atomic_setup_commit() directly - Jani

VCPI is only sort of the correct term here, originally the majority of this
code simply referred to timeslots vaguely as "slots" - and since I started
working on it and adding atomic functionality, the name "VCPI slots" has
been used to represent time slots.
Now that we actually have consistent access to the DisplayPort spec thanks
to VESA, I now know this isn't actually the proper term - as the
specification refers to these as time slots.
Since we're trying to make this code as easy to figure out as possible,
let's take this opportunity to correct this nomenclature and call them by
their proper name - timeslots. Likewise, we rename various functions
appropriately, along with replacing references in the kernel documentation
and various debugging messages.
It's important to note that this patch series leaves the legacy MST code
untouched for the most part, which is fine since we'll be removing it soon
anyhow. There should be no functional changes in this series.

1. struct _vcs_dpi_soc_bounding_box_st's creation/destruction

2. Throwing "temp" varibles in structs everywhere doesn't make

The timing programming inside DCN is far from trivial, it has multiple
parameters associated with that, and the lack of documentation does not
help comprehend this already complicated topic. This commit tries to
improve this situation by expanding the documentation of dc_crtc_timing
and the VTG program function.

[Why & How]
Depending on how the clock table is constructed from PMFW we can run
into issues where we don't think we have enough bandwidth available
due to FCLK too low - eg. when the FCLK table contains invalid entries
or a single entry.
We should always pick up the maximum clocks for each state as a final
state in this case to prevent validation from failing if the table is
malformed.
We should also contain sensible defaults in the case where values
are invalid.
Redfine the clock table structures by adding a 314 prefix to make
debugging these issues easier by avoiding symbol name clashes.
Overall this policy more closely aligns to how we did things for 315,
but because of how the voltage rail is setup we should favor keeping
DCFCLK low rather than DISPCLK or DPPCLK - so use the max for those
in every entry.

[Why]
Recent backport from opensource broke the Nightly tool build
that tests DC and DML for bugs and regressions. This was
because the backport had a header inclusion that was not
consistent with the AMD style of including headers was allowed
to be merged back in DML code that caused tool compilation
failures.
[How]
Modify the way in which the header file in included so that it
is consistent with AMD style of including headers. This then
automatically fixes the tool compilation process and also
helps maintain the code quality and consistency.

[Why]
Some pixel clock values could cause HDMI TMDS SSCPs to be misaligned
between different HDMI lanes when using YCbCr420 10-bit pixel format.
BIOS functions for transmitter/encoder control take pixel clock in kHz
increments, whereas the function for setting the pixel clock is in 100Hz
increments. Setting pixel clock to a value that is not on a kHz boundary
will cause the issue.
[How]
Round pixel clock down to nearest kHz in 10/12-bpc cases.

Since "rn_clk_mgr.h" needs ‘struct clk_mgr_internal’ which is declared
in "clk_mgr_internal.h", include "clk_mgr_internal.h" in "rn_clk_mgr.h"
instead of in its source file.
Because of the change above, change the order of '#include
"rn_clk_mgr.h"', so that the necessary structs are visible to
dcn20_clk_mgr.h.

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.

align the naming with other helpers. The plane helpers are for non-atomic
modesetting and exporting them will simplify a later conversion of drivers
to atomic modesetting.
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
number of forward declarations.

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.

[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.

[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

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.

[Why]
Changes from "Fix for dmub outbox notification enable" need to land
in DM or DMUB outbox notification would be disabled.
[How]
Enable outbox notification only after interrupt are enabled and IRQ

once outbox notification is enabled.

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.

Various DCE versions had trouble with 36 bpp lb depth, requiring fixes,
last time in commit 353ca0fa56 ("drm/amd/display: Fix 10bit 4K display
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

[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().

[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.

[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

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.

[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.

[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.

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.

validation from passing.

[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

Sometimes when trying to enable some feature, we have to define some
values with educated guesses, but we mark those values as TBD, which
means "To Be Determined". However, the correct way to approach it is by
loading that information from the firmware. Anyway, some of the values
that we were experimenting with caused this issue:
ERROR: modpost: "__muldf3" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
This commit fixes this issue by removing the division by two since it is
harmless in this case.

error message:

This was caused because we were trying to assign an unsigned int to a

Some userspace expect a backwards compatible modifier on DCN32/321. For
hardware with num_pipes more than 16, we expose the most efficient
modifier first. As a fall back method, we need to expose slightly inefficient
modifier AMD_FMT_MOD_TILE_GFX9_64K_R_X after the best option.
Also set the number of packers to fixed value as required per hardware
documentation. This value is cached during hardware initialization and
can be read through the base driver.

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.

behaviour. There is a clash with FCLK message due to inconsitent PMFW
headers.

Only on VG, if external display is disconnected during S3 suspend, the

[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()

Revert the commit because:

dm_set_dpms_off() tries to update one mst stream only which is

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")

In cases where there are multiple eDP instances, DMUB needs to know
which instance the command is for. Today, the field for specifying the
panel_inst exists in both dmub_cmd_update_dirty_rect_data and
dmub_cmd_update_cursor_info_data.
For cursor updates, we already specify the panel_inst, but that's not
the case for dirty_rect updates. Today, a value of '0' is used (due
to initial memsetting of the cmd struct to 0)

In dc_dmub_update_dirty_rect(), Call dc_get_edp_link_panel_inst() to get
the panel_inst, and fill it in the DMUB cmd struct.

[Why]
PSR-SU Rate Control - or PSR-SU-RC - enables PSR-SU panels to work with
variable refresh rate to allow for more power savings. Lowering the
refresh rate can increase PSR residency by expanding the eDP main link
shut down duration. It can also lower panel power consumption.
There is a complication with PSR, since the eDP main link can be shut
down. Therefore, the timing controller (TCON) on the eDP sink nees to be
able to scan out its remote buffer independent of the main link. To
allow the eDP source to specify the sink's refresh rate while the link
is off, vendor-specific DPCD registers are used. This allows the eDP
source to then "Rate Control" the panel during PSR active.
[How]
Add DC support to communicate with PSR-SU-RC supported eDP sinks. The
sink will need to know the desired VTotal during PSR active.
This change only adds support to DC, support in amdgpu_dm is still
pending to enable this fully.

1. When HPD deassertion is pulled in the middle of
enabe stream link training, we will abort current training
and turn off PHY. This causes current link settings
to be zeroed this causes later stream enablement
sequence to fail as we prefer to carry on enablement
process despite of link training failure for SST.
2. When HPD is toggled after detection before before
the enable stream sequence as a result. There could be
a race condition where we could end up enable stream based
on the previous link even though the link is updated
after the HPD toggle. This causes an issue where our link
bandwidth is no longer enough to accommodate the timing
therefore causes us to oversubscribe MST payload time
slots. As discussed we decided to add basic sanity check
to make sure that our code can handle the oversubscription
failure silently without system hang.
[how]
1. Keep PHY powered on when HPD is deasserted during
enable stream and wait for the detection sequence to power
it off later.
2. Do not allocate payload if the required timeslot for
current timing is greater than 64 timeslots.

[WHY]
For additional power savings, PSR SU (also referred to as PSR2) can be
enabled on eDP panels with PSR SU support.
PSR2 saves more power compared to PSR1 by allowing more opportunities
for the display hardware to be shut down. In comparison to PSR1, Shut
down can now occur in-between frames, as well as in display regions
where there is no visible update. In otherwords, it allows for some
display hw components to be enabled only for a **selectively updated**
region of the visible display. Hence PSR SU.
[HOW]
To define the SU region, support from the OS is required. OS needs to
inform driver of damaged regions that need to be flushed to the eDP
panel. Today, such support is lacking in most compositors.
Therefore, an in-between solution is to implement PSR SU for MPO and
cursor scenarios. The plane bounds can be used to define the damaged
region to be flushed to panel. This is achieved by:
* Leveraging dm_crtc_state->mpo_requested flag to identify when MPO is
enabled.
* If MPO is enabled, only add updated plane bounds to dirty region.
Determine plane update by either:
* Existence of drm damaged clips attached to the plane (added by a
damage-aware compositor)
* Change in fb id (flip)
* Change in plane bounds (position and dimensions)
* If cursor is enabled, the old_pos and new_pos of cursor plus cursor
size is used as damaged regions(*).
(*) Cursor updates follow a different code path through DC. PSR SU for
cursor is already implemented in DC, and the only thing required to
enable is to set DC_PSR_VERSION_SU_1 on the eDP link. See
dcn10_dmub_update_cursor_data().

[Why]
Previously we used to send FCLK P-state enable messages upon each call
to update_clocks based on dml output. This resulted in increased message
transactions between DC and PMFW.
[How]
Update the code to check safe_to_lower status and send the message based
on dml input only on boot. This reduces message transactions. Also
remove other unwanted code based on current code status.

[Why]
HUBP_UNBOUNDED_REQ_MODE and CURSOR_REQ_MODE are normally set together.
In hubp32_prepare_subvp_buffering() call, CURSOR_REQ_MODE is set based on
whether SubVP is enabled or not. For non MPO case, both REQ_MODE
registers are set to 1. But since SubVP is not enabled, then
CURSOR_REQ_MODE is set to 0, overriding the previous value.
[How]
Do not set CURSOR_REQ_MODE to 0 if SubVP is not enabled. This
will allow CURSOR_REQ_MODE to stay as 1 in the non MPO case.
Add note to follow up and check case for single pipe MPO and
SubVP enabled as this would cause both REQ_MODE registers to be
set to 0 but SubVP enabled would override CURSOR_REQ_MODE to 1.

[Why]
When enabling an HPO stream for the first time after having previously
enabled a DIO stream there may be lingering DIO FIFO errors even though
the DIO is no longer enabled.
These can cause display clock change to hang if we don't apply the
OTG disable workaround since the ramping logic is tied to OTG on.
[How]
The workaround wasn't being applied in the sequence of:
1 DIO stream
0 streams
1 HPO stream
because current_state has no stream or planes in its context - and
it's only swapped after optimize has finished.
We should be using the incoming context instead to determine whether
this logic is needed or not.

According to the KMS man page, there is a
"Coverage" alpha blend mode that assumes the
pixel color values have NOT been pre-multiplied
and will be done when the actual blending to
the background color values happens.
Previously, this mode hasn't been enabled
in our driver and it was assumed that all
normal overlay planes are pre-multiplied
by default.
When a 3rd party app is used to input a image
in a specific format, e.g. PNG, as a source
of a overlay plane to blend with the background
primary plane, the pixel color values are not
pre-multiplied. So by adding "Coverage" blend
mode, our driver will support those cases.
Issue fixed: Overlay plane alpha channel blending is incorrect
Issue tracker: https://gitlab.freedesktop.org/drm/amd/-/issues/1769
Reference:
https://dri.freedesktop.org/docs/drm/gpu/drm-kms.html#plane-composition-properties
Adding Coverage support also enables IGT
kms_plane_alpha_blend Coverage subtests:
1. coverage-7efc
2. coverage-vs-premult-vs-constant
Changes
1. Add DRM_MODE_BLEND_COVERAGE blend mode capability
2. Add "pre_multiplied_alpha" flag for Coverage case
3. Read the correct flag and set the DCN MPCC
pre_multiplied register bit (only on overlay plane)

[Why]
A display clock change hang can occur when switching between DIO and HPO
enabled modes during the optimize_bandwidth in dc_commit_state_no_check
call.
This happens when going from 4k120 8bpc 420 to 4k144 10bpc 444.
Display clock in the DIO case is 1200MHz, but pixel rate is 600MHz
because the pixel format is 420.
Display clock in the HPO case is less (800MHz?) because of ODM combine
which results in a smaller divider.
The DIO is still active in prepare but not active in the optimize which
results in the hang occuring.
During this change there are no planes on the stream so it's safe to
apply the workaround, but dpms_off = false and signal type is not
virtual.
[How]
Check for plane_count == 0, no planes on the stream.
It's easiest to check pipe->plane_state == NULL as an equivalent check
rather than trying to search for the stream status in the context

[Why]
Second eDP can send display off notification through HPD
but DC isn't hooked up to handle. Some primary eDP panels
will toggle on/off incorrectly if it's enabled generically.
[How]
Extend the debug option to allow individually enabling hotplug
either the first eDP or the second eDP in a dual eDP system.

"Fix some -Wstringop-overflow warnings when building with GCC-11. All

* tag 'Wstringop-overflow-fixes-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux:

drm/amd/display: Fix Wstringop-overflow warnings in dc_link_dp.c

As drm_connector already have the display_info, instead of creating
"output_bpc" debugfs in vendor specific driver, move the logic to
the drm layer.
This patch will also move "Current" bpc to the crtc debugfs from
connector debugfs, since we are getting this info from crtc_state.

[Why & How]
There is a chance where the RX issues HPD deassert in the
middle of link training, this will cause our logic to
abort link training and turn off link. However our payload
allocation logic needs to use current link settings to
determine average time slot per MTP. This will need to
use current link bandwidth as divider. This causes divide
by zero error occasionally. The fix is to skip DP2.0 payload
allocation logic if current link is not in 128b/132b mode.

From [1], I realized two other calls to dcn30 code are associated with
FPU operations and are not protected by DC_FP_* macros:
* dcn30_populate_dml_writeback_from_context()
* dcn30_set_mcif_arb_params()
So, since FPU-associated code is not fully isolated in dcn30, and
dcn3.1.x reuses them, let's wrap their calls properly.
Note: this patch complements the fix from [1].
