Wayne Lin 34b6c4b130 drm/amd/display: Fix phy id mapping issue for secure display
[Why]
Under mst scenario, mst streams are from the same link_enc_hw_inst.
As the result, can't utilize that as the phy index for distinguising
different stream sinks.

[How]
Sort the connectors by:
link_enc_hw_instance->mst tree depth->mst RAD

After sorting the phy index assignment, store connector's relevant info
into dm mapping array. Once need the index, just look up the static
array.

Wayne Lin 37a8f9b0c9 drm/amd/display: Adjust dc_stream_forward_crc_window to accept assignment of phy_id
[Why]
For mst streams under same topology, stream->link->link_enc_hw_inst are the same and
hence can't distinguish the crc window setting.

[How]
Firstly adjust dc_stream_forward_crc_window to accept assignment of phy_id. Follow up
another patch to determine the phy_id at dm layer.

Mario Limonciello ea5d493498 drm/amd: Add the capability to mark certain firmware as "required"
Some of the firmware that is loaded by amdgpu is not actually required.
For example the ISP firmware on some SoCs is optional, and if it's not
present the ISP IP block just won't be initialized.

The firmware loader core however will show a warning when this happens
like this:
```
Direct firmware load for amdgpu/isp_4_1_0.bin failed with error -2
```

To avoid confusion for non-required firmware, adjust the amd-ucode helper
to take an extra argument indicating if the firmware is required or
optional.

On optional firmware use firmware_request_nowarn() instead of
request_firmware() to avoid the warnings.

Not all platforms provide the full range of PWM backlight capabilities
supported by the hardware through ATIF.
Use the generic drm panel minimum backlight quirk infrastructure to
override the capabilities where necessary.

Testing the backlight quirk together with the "panel_power_savings"
sysfs file has not shown any negative impact.
One quirk seems to be that 0% at panel_power_savings=0 seems to be
slightly darker than at panel_power_savings=4.

Wayne Lin bc068194f5 drm/amd/display: Don't write DP_MSTM_CTRL after LT
[Why]
Observe after suspend/resme, we can't light up mst monitors under specific
mst hub. The reason is that driver still writes DPCD DP_MSTM_CTRL after LT.
It's forbidden even we write the same value for that dpcd register.

[How]
We already resume the mst branch device dpcd settings during
resume_mst_branch_status(). Leverage drm_dp_mst_topology_queue_probe() to
only probe the topology, not calling drm_dp_mst_topology_mgr_resume() which
will set DP_MSTM_CTRL as well.

Aurabindo Pillai 8a79f7cdbb drm/amd/display: temp w/a for DP Link Layer compliance
[Why&How]
Disabling P-State support on full updates for DCN401 results in
introducing additional communication with SMU. A UCLK hard min message
to SMU takes 4 seconds to go through, which was due to DCN not allowing
pstate switch, which was caused by incorrect value for TTU watermark
before blanking the HUBP prior to DPG on for servicing the test request.

Fix the issue temporarily by disallowing pstate changes for compliance
test while test request handler is reworked for a proper fix.

vblank immediate disable currently does not work for all asics. On

Add a workaround to enable immediate disable only on APUs for now. This
adds a 2-frame delay for triggering idle optimization, which is a
negligible overhead.

Hamza Mahfooz 2fe79508d9 drm/amd/display: fix hibernate entry for DCN35+
Since, two suspend-resume cycles are required to enter hibernate and,
since we only need to enable idle optimizations in the first cycle
(which is pretty much equivalent to s2idle). We can check in_s0ix, to
prevent the system from entering idle optimizations before it actually
enters hibernate (from display's perspective). Also, call
dc_set_power_state() before dc_allow_idle_optimizations(), since it's
safer to do so because dc_set_power_state() writes to DMUB.

Mario Limonciello c6a837088b drm/amd/display: Fetch the EDID from _DDC if available for eDP
Some manufacturers have intentionally put an EDID that differs from
the EDID on the internal panel on laptops.

Attempt to fetch this EDID if it exists and prefer it over the EDID
that is provided by the panel. If a user prefers to use the EDID from
the panel, offer a DC debugging parameter that would disable this.

Roman Li 442702b490 drm/amd/display: Align static screen idle worker with IPX mode
[Why]
Idle worker thread serves for periodic detection of HPD while system is in IPS2.
Currently it is used in headless and static screen scenarios.
IPX can be configured not to execute IPS2 for static screen.
In this case idle worker is redundant.

[How]
Only use periodic detection for static screen if IPS is fully enabled.

This is caused by lost memory during early init phase. First time driver
is removed, memory is freed but when second time the driver is inserted,
VBIOS dmub is not active, since the PSP policy is to retain the driver
loaded version on subsequent warm boots. Hence, communication with VBIOS
DMUB fails.

Fix this by aborting further communication with vbios dmub and release
the memory immediately.

Fangzhi Zuo 4641169a8c drm/amd/display: Fix incorrect DSC recompute trigger
A stream without dsc_aux should not be eliminated from
the dsc determination. Whether it needs a dsc recompute depends on
whether its mode has changed or not. Eliminating such a no-dsc stream
from the dsc determination policy will end up with inconsistencies
in the new dc_state when compared to the current dc_state,
triggering a dsc recompute that should not have happened.

Fangzhi Zuo 352c3165d2 drm/amd/display: Restore Optimized pbn Value if Failed to Disable DSC
Existing last step of dsc policy is to restore pbn value under minimum compression
when try to greedily disable dsc for a stream failed to fit in MST bw.
Optimized dsc params result from optimization step is not necessarily the minimum compression,
therefore it is not correct to restore the pbn under minimum compression rate.

Restore the pbn under minimum compression instead of the value from optimized pbn could result
in the dsc params not correct at the modeset where atomic_check failed due to not
enough bw. One or more monitors connected could not light up in such case.

Restore the optimized pbn value, instead of using the pbn value under minimum
compression.

Hamza Mahfooz 8d20a066fa drm/amd/display: change the panel power savings level without a modeset
We don't actually need to request that the compositor does a full
modeset to modify the panel power savings level, we can instead
just make a request to DMUB, to set the new level dynamically.

Currently amdgpu takes backlight caps provided by the ACPI tables
on systems as is.  If the firmware sets maximums that are too low
this means that users don't get a good experience.

To avoid having to maintain a quirk list of such systems, do a sanity
check on the values.  Check that the spread is at least half of the
values that amdgpu would use if no ACPI table was found and if not
use the amdgpu defaults.

Leo Li 0c8c5bdd7e drm/amd/display: Add all planes on CRTC to state for overlay cursor
[Why]

DC has a special commit path for native cursor, which use the built-in
cursor pipe within DCN planes. This update path does not require all
enabled planes to be added to the list of surface updates sent to DC.

This is not the case for overlay cursor; it uses the same path as MPO
commits. This update path requires all enabled planes to be added to the
list of surface updates sent to DC. Otherwise, DC will disable planes
not inside the list.

[How]

If overlay cursor is needed, add all planes on the same CRTC as this
cursor to the atomic state. This is already done for non-cursor planes
(MPO), just before the added lines.

Leo Li 578aab4ecc drm/amd/display: Do not reset planes based on crtc zpos_changed
[Why]

drm_normalize_zpos will set the crtc_state->zpos_changed to 1 if any of
it's assigned planes changes zpos, or is removed/added from it.

To have amdgpu_dm request a plane reset on this is too broad. For
example, if only the cursor plane was moved from one crtc to another,
the crtc's zpos_changed will be set to true. But that does not mean that
the underlying primary plane requires a reset.

[How]

Narrow it down so that only the plane that has a change in zpos will
require a reset.

As a future TODO, we can further optimize this by only requiring a reset
on z-order change. Z-order is different from z-pos, since a zpos change
doesn't necessarily mean the z-ordering changed, and DC should only
require a reset if the z-ordering changed.

For example, the following zpos update does not change z-ordering:

    Plane A: zpos 2 -> 3
    Plane B: zpos 1 -> 2
    => Plane A is still on top of plane B: no reset needed

Whereas this one does change z-ordering:

    Plane A: zpos 2 -> 1
    Plane B: zpos 1 -> 2
    => Plane A changed from on top, to below plane B: reset needed

So, acquire the dc lock before calling into dc to update backlight - we

disallow IPS before calling into dc, then allow IPS afterwards (if it
was previously allowed).

Leo Li 28d43d0895 drm/amd/display: Determine IPS mode by ASIC and PMFW versions
[Why]

DCN IPS interoperates with other system idle power features, such as
Zstates.

On DCN35, there is a known issue where system Z8 + DCN IPS2 causes a
hard hang. We observe this on systems where the SBIOS allows Z8.

Though there is a SBIOS fix, there's no guarantee that users will get it
any time soon, or even install it. A workaround is needed to prevent
this from rearing its head in the wild.

[How]

For DCN35, check the pmfw version to determine whether the SBIOS has the
fix. If not, set IPS1+RCG as the deepest possible state in all cases
except for s0ix and display off (DPMS). Otherwise, enable all IPS

Leo Li a08d75927f drm/amd: Introduce additional IPS debug flags
[Why]

Idle power states (IPS) describe levels of power-gating within DCN. DM
and DC is responsible for ensuring that we are out of IPS before any DCN
programming happens. Any DCN programming while we're in IPS leads to
undefined behavior (mostly hangs).

Because IPS intersects with all display features, the ability to disable
IPS by default while ironing out the known issues is desired. However,
disabing it completely will cause important features such as s0ix entry
to fail.

Therefore, more granular IPS debug flags are desired.

[How]

Extend the dc debug mask bits to include the available list of IPS
debug flags.

All the flags should work as documented, with the exception of
IPS_DISABLE_DYNAMIC. It requires dm changes which will be done in
later changes.

drm/amd/display: use new vblank enable policy for DCN35+
Hook up drm_crtc_vblank_on_config() in amdgpu_dm. So, that we can enable
PSR and other static screen optimizations more quickly, while avoiding
stuttering issues that are accompanied by the following dmesg error:

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

This also allows us to mimic how vblanking is handled by the Windows
amdgpu driver. Specifically, we wait two idle frames before disabling
the vblank timer there.

Srinivasan Shanmugam cd9e9e0852 drm/amd/display: Add null check for 'afb' in amdgpu_dm_plane_handle_cursor_update (v2)
This commit adds a null check for the 'afb' variable in the
amdgpu_dm_plane_handle_cursor_update function. Previously, 'afb' was
assumed to be null, but was used later in the code without a null check.
This could potentially lead to a null pointer dereference.

Changes since v1:
- Moved the null check for 'afb' to the line where 'afb' is used. (Alex)

[Why & How]
1. After allowing idle optimizations, hw programming is disallowed.
2. Before hw programming, we need to disallow idle optimizations.

Otherwise, in scenario 1, we will immediately kick hw out of idle
optimizations with register access.

Scenario 2 is less of a concern, since any register access will kick
hw out of idle optimizations. But we'll do it early for correctness.

Leo Li 7fb363c575 drm/amd/display: Let drm_crtc_vblank_on/off manage interrupts
[Why]
We manage interrupts for CRTCs in two places:
1. In manage_dm_interrupts(), when CRTC get enabled or disabled
2. When drm_vblank_get/put() starts or kills the vblank counter, calling
   into amdgpu_dm_crtc_set_vblank()

The interrupts managed by these twp places should be identical.

[How]
Since manage_dm_interrupts() already use drm_crtc_vblank_on/off(), just
move all CRTC interrupt management into amdgpu_dm_crtc_set_vblank().

This has the added benefit of disabling all CRTC and HUBP interrupts
when there are no vblank requestors.

Note that there is a TODO item - unchanged from when it was first
introduced - to properly identify the HUBP instance from the OTG
instance, rather than just assume direct mapping.

Tom Chung f91a9af09d drm/amd/display: Fix VRR cannot enable
[Why]
Sometimes the VRR cannot enable after login to the desktop.

User space may call the DRM_IOCTL_MODE_GETCONNECTOR right after
the DRM_IOCTL_MODE_RMFB.

After calling DRM_IOCTL_MODE_RMFB to remove all the frame buffer
and it will cause the driver to disable the crtc and disable the
link while calling the link_set_dpms_off().

It will cause the dpcd read failed in amdgpu_dm_update_freesync_caps()
while try to get the DP_MSA_TIMING_PAR_IGNORED capability and think
the sink side does not support VRR.

[How]
Use the dpcd_caps.allow_invalid_MSA_timing_param flag instead of
reading from dpcd directly.

dpcd_caps.allow_invalid_MSA_timing_param flag is updated during HPD.
It is safe to replace the original method.

Leo Li 38e0c3df6d drm/amd/display: Move PRIMARY plane zpos higher
[Why]

Compositors have different ways of assigning surfaces to DRM planes for
render offloading. It may decide between various strategies: overlay,
underlay, or a mix of both (see here for more info:
https://gitlab.freedesktop.org/emersion/libliftoff/-/issues/76)

One way for compositors to implement the underlay strategy is to assign
a higher zpos to the DRM_PRIMARY plane than the DRM_OVERLAY planes,
effectively turning the DRM_OVERLAY plane into an underlay plane.

Today, amdgpu attaches an immutable zpos of 0 to the DRM_PRIMARY plane.
This however, is an arbitrary restriction. DCN pipes are general
purpose, and can be arranged in any z-order. To support compositors
using this allocation scheme, we can set a non-zero immutable zpos for
the PRIMARY, allowing the placement of OVERLAYS (mutable zpos range
0-254) beneath the PRIMARY.

[How]

Assign a zpos = #no of OVERLAY planes to the PRIMARY plane. Then, clean
up any assumptions in the driver of PRIMARY plane having the lowest
zpos.

DCN is the display hardware for amdgpu. DRM planes are backed by DCN
hardware pipes, which carry pixel data from one end (memory), to the
other (output encoder).

Each DCN pipe has the ability to blend in a cursor early on in the
pipeline. In other words, there are no dedicated cursor planes in DCN,
which makes cursor behavior somewhat unintuitive for compositors.

For example, if the cursor is in RGB format, but the top-most DRM plane
is in YUV format, DCN will not be able to blend them. Because of this,
amdgpu_dm rejects all configurations where a cursor needs to be enabled
on top of a YUV formatted plane.

From a compositor's perspective, when computing an allocation for
hardware plane offloading, this cursor-on-yuv configuration result in an
atomic test failure. Since the failure reason is not obvious at all,
compositors will likely fall back to full rendering, which is not ideal.

Instead, amdgpu_dm can try to accommodate the cursor-on-yuv
configuration by opportunistically reserving a separate DCN pipe just
for the cursor. We can refer to this as "overlay cursor mode". It is
contrasted with "native cursor mode", where the native DCN per-pipe
cursor is used.

[How]

On each crtc, compute whether the cursor plane should be enabled in
overlay mode. If it is, mark the CRTC as requesting overlay cursor mode.

Overlay cursor should be enabled whenever there exists a underlying
plane that has YUV format, or is scaled differently than the cursor. It
should also be enabled if there is no underlying plane, or if underlying
planes do not cover the entire CRTC.

During DC validation, attempt to enable a separate DCN pipe for the
cursor if it's in overlay mode. If that fails, or if no overlay mode is
requested, then fallback to native mode.

v2:
* Update commit message for when overlay cursor should be enabled
* Also consider scale and no-underlying-plane case (cursor on crtc bg)
* Consider all underlying planes when determinig overlay/native, not
  just the plane immediately beneath the cursor, as it may not cover the
  entire CRTC.
* Fix typo s/decending/descending/
* Force native cursor on pre-DCN hardware

Wayne Lin fcf6a49d79 drm/amd/display: Don't refer to dc_sink in is_dsc_need_re_compute
[Why]
When unplug one of monitors connected after mst hub, encounter null pointer dereference.

It's due to dc_sink get released immediately in early_unregister() or detect_ctx(). When
commit new state which directly referring to info stored in dc_sink will cause null pointer
dereference.

[how]
Remove redundant checking condition. Relevant condition should already be covered by checking
if dsc_aux is null or not. Also reset dsc_aux to NULL when the connector is disconnected.

Mario Limonciello 2fe87f54ab drm/amd/display: Set default brightness according to ACPI
Currently, amdgpu will always set up the brightness at 100% when it
loads.  However this is jarring when the BIOS has it previously
programmed to a much lower value.

The ACPI ATIF method includes two members for "ac_level" and "dc_level".
These represent the default values that should be used if the system is
brought up in AC and DC respectively.

Use these values to set up the default brightness when the backlight
device is registered.

Linus Torvalds d6a326d694 tracing: Remove second argument of __assign_str()
The __assign_str() macro logic of the TRACE_EVENT() macro was optimized so
 that it no longer needs the second argument. The __assign_str() is always
 matched with __string() field that takes a field name and the source for
 that field:
 
   __string(field, source)
 
 The TRACE_EVENT() macro logic will save off the source value and then use
 that value to copy into the ring buffer via the __assign_str(). Before
 commit c1fa617cae ("tracing: Rework __assign_str() and __string() to not
 duplicate getting the string"), the __assign_str() needed the second
 argument which would perform the same logic as the __string() source
 parameter did. Not only would this add overhead, but it was error prone as
 if the __assign_str() source produced something different, it may not have
 allocated enough for the string in the ring buffer (as the __string()
 source was used to determine how much to allocate)
 
 Now that the __assign_str() just uses the same string that was used in
 __string() it no longer needs the source parameter. It can now be removed.

Steven Rostedt (Google) 2c92ca849f tracing/treewide: Remove second parameter of __assign_str()
With the rework of how the __string() handles dynamic strings where it
saves off the source string in field in the helper structure[1], the
assignment of that value to the trace event field is stored in the helper
value and does not need to be passed in again.

This means that with:

  __string(field, mystring)

Which use to be assigned with __assign_str(field, mystring), no longer
needs the second parameter and it is unused. With this, __assign_str()
will now only get a single parameter.

There's over 700 users of __assign_str() and because coccinelle does not
handle the TRACE_EVENT() macro I ended up using the following sed script:

  git grep -l __assign_str | while read a ; do
      sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file;
      mv /tmp/test-file $a;
  done

I then searched for __assign_str() that did not end with ';' as those
were multi line assignments that the sed script above would fail to catch.

Note, the same updates will need to be done for:

  __assign_str_len()
  __assign_rel_str()
  __assign_rel_str_len()

I tested this with both an allmodconfig and an allyesconfig (build only for both).

Pull drm updates from Dave Airlie:
 "This is the main pull request for the drm subsystems for 6.10.

  In drivers the main thing is a new driver for ARM Mali firmware based
  GPUs, otherwise there are a lot of changes to amdgpu/xe/i915/msm and
  scattered changes to everything else.

  In the core a bunch of headers and Kconfig was refactored, along with
  the addition of a new panic handler which is meant to provide a user
  friendly message when a panic happens and graphical display is
  enabled.

  New drivers:
   - panthor: ARM Mali/Immortalis CSF-based GPU driver

  Core:
   - add a CONFIG_DRM_WERROR option
   - make more headers self-contained
   - grab resv lock in pin/unpin
   - fix vmap resv locking
   - EDID/eDP panel matching
   - Kconfig cleanups
   - DT sound bindings
   - Add SIZE_HINTS property for cursor planes
   - Add struct drm_edid_product_id and helpers.
   - Use drm device based logging in more drm functions.
   - drop seq_file.h from a bunch of places
   - use drm_edid driver conversions

  dp:
   - DP Tunnel documentation
   - MST read sideband cap
   - Adaptive sync SDP prep work

  ttm:
   - improve placement for TTM BOs in idle/busy handling

  panic:
   - Fixes for drm-panic, and option to test it.
   - Add drm panic to simpledrm, mgag200, imx, ast

  bridge:
   - improve init ordering

[Why]
This fixes a bug introduced by commit c536555451 ("drm/amd/display: dsc

The change caused light-up issues with a second display that required
DSC on some MST docks.

[How]
Use Virtual DPCD for DSC caps in MST case.

[Limitations]
This change only affects MST DSC devices that follow specifications
additional changes are required to check for old MST DSC devices such as
ones which do not check for Virtual DPCD registers.

[Why & How]
User can get the panel replay capability and state for debug.

sudo cat /sys/kernel/debug/dri/0/eDP-1/replay_capability
"Sink support: no" - if panel doesn't support Replay
"Sink support: yes" - if panel supports Replay
"Driver support: no\n" - if driver doesn't support Replay
"Driver support: yes\n" - if driver supports Replay

sudo cat /sys/kernel/debug/dri/0/eDP-1/replay_state
It will return current panel replay state

Hersen Wu 892b41b16f drm/amd/display: Fix incorrect DSC instance for MST
[Why] DSC debugfs, such as dp_dsc_clock_en_read,
use aconnector->dc_link to find pipe_ctx for display.
Displays connected to MST hub share the same dc_link.
DSC instance is from pipe_ctx. This causes incorrect
DSC instance for display connected to MST hub.

[How] Add aconnector->sink check to find pipe_ctx.

Tobias Jakobi 7c0ac60338 drm/amd/display: Add MSF panel to DPCD 0x317 patch list
This 8.4 inch panel is integrated in the Ayaneo Kun handheld
device. The panel resolution is 2560×1600, i.e. it has
portrait dimensions.

Decoding the EDID shows:
Manufacturer: MSF
Model: 4099
Display Product Name: 'TV080WUM-NL0 '

Judging from the product name this might be a clone of a
BOE panel, but with larger dimensions.

Panel frequently shows non-functional backlight control. Adding
some debug prints to update_connector_ext_caps() shows that
something the OLED bit of ext_caps is set, and then the driver
assumes that backlight is controlled via AUX.

Forcing backlight control to PWM via amdgpu.backlight=0 restores
backlight operation.

Roman Li afca033f10 drm/amd/display: Add periodic detection for IPS
[Why]
HPD interrupt cannot be handled in IPS2 state.
So if there's a display topology change while system in IPS2
it can be missed.

[How]
Implement worker to check each 5 sec in IPS for HPD.

Wayne Lin 202dc359ad drm/amd/display: Defer handling mst up request in resume
[Why]
Like commit ec5fa9fcde ("drm/amd/display: Adjust the MST resume flow"), we
want to avoid handling mst topology changes before restoring the old state.
If we enable DP_UP_REQ_EN before calling drm_atomic_helper_resume(), have
changce to handle CSN event first and fire hotplug event before restoring the
cached state.

[How]
Disable mst branch sending up request event before we restoring the cached state.
DP_UP_REQ_EN will be set later when we call drm_dp_mst_topology_mgr_resume().

Harry Wentland e582c097d3 drm/amd/display: Always use legacy way of setting cursor on DCE
Some IGT tests fail with the new atomic cursor updates
when running on older DCE-based ASICs. To work around
these issues keep calling the amdgpu_dm_commit_cursors
for each cursor update on DCE, even if those cursor
updates coincide with other plane updates.

Harry Wentland 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.

Harry Wentland 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.
