Roman Li f9663cbd46 drm/amd/display: remove early return from dm_late_init
[Why]
ABM feature initialization was not executed due to early return.

dm_late_init() had an early return in case if DMCU is not used.
With the implementation of ABM on DMUB, DMCU can be disabled
but ABM still needs to be initialized.

[How]
Remove verification for DMCU from the top of the function.
The existing logic will handle the case when DMCU is not used.

George Shen 6c95320d01 drm/amd/display: Rename set_mst_bandwidth to align with DP spec
[Why]
The function set_mst_bandwidth is poorly name since it isn't clear what
it does, and it also does not reflect any part of the allocation sequence
described in the DP spec.

[How]
Rename the function set_mst_bandwidth to set_throttled_vcp_size.

Aric Cyr e8cb7a4dd9 drm/amd/display: Flip pending check timeout due to disabled hubp
[Why]
When pipe locks are being taken we wait for flip pending to clear first.
In some cases the pipe mapping is changed and the pending we're checking
for will never clear.

[How]
Don't check disabled pipes for flip pending.

Ashley Thomas 172c9b7781 drm/amd/display: Power eDP panel back ON before link training retry
[why]
When link training failures occur for eDP, dp_disable_link_phy
is called which powers OFF eDP panel. After link training retry
delay, the next retry begins by calling dp_enable_link_phy
which does not issue a correspnding eDP panel power ON, leaving
panel powered OFF which leads to display OFF/dark.

[how]
Power ON eDP before next link training retry.

Wesley Chalmers 05e3d830fa drm/amd/display: Only use offset for first ODM pipe
[WHY]
Only the first pipe in ODM combine group should have nonzero recout
offset. All other pipes should have recout offset 0;
otherwise there will be gaps in the image.

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

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

Since ODM combine can only combine pipes horizontally, nothing needs to
be done for recout.y.

Rodrigo Siqueira 4b4f21ff7f drm/amd/display: Check clock table return
During the load processes for Renoir, our display code needs to retrieve
the SMU clock and voltage table, however, this operation can fail which
means that we have to check this scenario. Currently, we are not
handling this case properly and as a result, we have seen the following
dmesg log during the boot:

RIP: 0010:rn_clk_mgr_construct+0x129/0x3d0 [amdgpu]
...
Call Trace:
 dc_clk_mgr_create+0x16a/0x1b0 [amdgpu]
 dc_create+0x231/0x760 [amdgpu]

This commit fixes this issue by checking the return status retrieved
from the clock table before try to populate any bandwidth.

If plane has changed, dcn20_detect_pipe_changes doesn't update dc_plane_state->update_flags, and the following dcn20_program_pipe can't reprogram hubp correctly.

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

[why]
Need a tool to retrigger a virtual hotplug for testing purposes with
force redetection in both DC and DM.

[how]
Emulate handle_hpd_irq for connector as if usermode would trigger
a hotplug. Perform DC link discovery, DM connector update, and
DM force atomic commit.

In order to trigger HPD on the connector user needs to echo 1 into

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

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

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

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

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

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

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

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

[why]
Current pipe merge and split logic only supports cases where new
dc_state is allocated and relies on dc->current_state to gather
information from previous dc_state.

Calls to validate_bandwidth on UPDATE_TYPE_MED would cause an issue
because there is no new dc_state allocated, and data in
dc->current_state would be overwritten during pipe merge.

hersen wu 6ee90e88b9 drm/amd/display: PSR eDP p-state warning occurs intermittently after unplug DP
[Why]
with eDP + DP, each display use one pipe. after DP unplugged, eDP switch
from one pipe to two pipes -- pipe split.  dpp1_cm_set_regamma_pwl will
be executed too. The duration from switch single pipe to dual pipes is a
little long which could let eDP enter PSR mode. upon two pipes for eDP
are setup, eDP PHY is disabled. front pipe is not really running to
fetch data from frame buffer. i.e., dchubp is not in normal working
status. execution of hubbub1_wm_change_req_wa may cause p-state warning.

[How]
disable eDP PSR before dc_commit_state. psr is disabled when execute
hubbub1_wm_change_req_wa.

Alvin Lee 81b437f57e drm/amd/display: Disconnect pipe separetely when disable pipe split
[Why]
When changing pixel formats for HDR (e.g. ARGB -> FP16)
there are configurations that change from 2 pipes to 1 pipe.
In these cases, it seems that disconnecting MPCC and doing
a surface update at the same time(after unlocking) causes
some registers to be updated slightly faster than others
after unlocking (e.g. if the pixel format is updated to FP16
before the new surface address is programmed, we get
corruption on the screen because the pixel formats aren't
matching). We separate disconnecting MPCC from the rest
of  the  pipe programming sequence to prevent this.

[How]
Move MPCC disconnect into separate operation than the
rest of the pipe programming.

1. There is a calculation that is using frame_time_in_us instead of

hersen wu 8b0379a857 drm/amd/display: dchubbub p-state warning during surface planes switch
[Why]
ramp_up_dispclk_with_dpp is to change dispclk, dppclk and dprefclk
according to bandwidth requirement. call stack: rv1_update_clocks -->
update_clocks --> dcn10_prepare_bandwidth / dcn10_optimize_bandwidth
--> prepare_bandwidth / optimize_bandwidth. before change dcn hw,
prepare_bandwidth will be called first to allow enough clock,
watermark for change, after end of dcn hw change, optimize_bandwidth
is executed to lower clock to save power for new dcn hw settings.

below is sequence of commit_planes_for_stream:
step 1: prepare_bandwidth - raise clock to have enough bandwidth
step 2: lock_doublebuffer_enable
step 3: pipe_control_lock(true) - make dchubp register change will
not take effect right way
step 4: apply_ctx_for_surface - program dchubp
step 5: pipe_control_lock(false) - dchubp register change take effect
step 6: optimize_bandwidth --> dc_post_update_surfaces_to_stream
for full_date, optimize clock to save power

at end of step 1, dcn clocks (dprefclk, dispclk, dppclk) may be
changed for new dchubp configuration. but real dcn hub dchubps are
still running with old configuration until end of step 5. this need
clocks settings at step 1 should not less than that before step 1.
this is checked by two conditions: 1. if (should_set_clock(safe_to_lower
, new_clocks->dispclk_khz, clk_mgr_base->clks.dispclk_khz) ||
new_clocks->dispclk_khz == clk_mgr_base->clks.dispclk_khz)
2. request_dpp_div = new_clocks->dispclk_khz > new_clocks->dppclk_khz

the second condition is based on new dchubp configuration. dppclk
for new dchubp may be different from dppclk before step 1.
for example, before step 1, dchubps are as below:
pipe 0: recout=(0,40,1920,980) viewport=(0,0,1920,979)
pipe 1: recout=(0,0,1920,1080) viewport=(0,0,1920,1080)
for dppclk for pipe0 need dppclk = dispclk

new dchubp pipe split configuration:
pipe 0: recout=(0,0,960,1080) viewport=(0,0,960,1080)
pipe 1: recout=(960,0,960,1080) viewport=(960,0,960,1080)
dppclk only needs dppclk = dispclk /2.

dispclk, dppclk are not lock by otg master lock. they take effect
after step 1. during this transition, dispclk are the same, but
dppclk is changed to half of previous clock for old dchubp
configuration between step 1 and step 6. This may cause p-state
warning intermittently.

[How]
for new_clocks->dispclk_khz == clk_mgr_base->clks.dispclk_khz, we
need make sure dppclk are not changed to less between step 1 and 6.
for new_clocks->dispclk_khz > clk_mgr_base->clks.dispclk_khz,
new display clock is raised, but we do not know ratio of
new_clocks->dispclk_khz and clk_mgr_base->clks.dispclk_khz,
new_clocks->dispclk_khz /2 does not guarantee equal or higher than
old dppclk. we could ignore power saving different between
dppclk = displck and dppclk = dispclk / 2 between step 1 and step 6.
as long as safe_to_lower = false, set dpclk = dispclk to simplify
condition check.

Nicholas Kazlauskas f6d7c7faf0 drm/amd/display: Drop dm_determine_update_type_for_commit
[Why]
This was added in the past to solve the issue of not knowing when
to stall for medium and full updates in DM.

Since DC is ultimately decides what requires bandwidth changes we
wanted to make use of it directly to determine this.

The problem is that we can't actually pass any of the stream or surface
updates into DC global validation, so we don't actually check if the new
configuration is valid - we just validate the old existing config
instead and stall for outstanding commits to finish.

There's also the problem of grabbing the DRM private object for
pageflips which can lead to page faults in the case where commits
execute out of order and free a DRM private object state that was
still required for commit tail.

[How]
Now that we reset the plane in DM with the same conditions DC checks
we can have planes go through DC validation and we know when we need
to check and stall based on whether the stream or planes changed.

We mark lock_and_validation_needed whenever we've done this, so just
go back to using that instead of dm_determine_update_type_for_commit.

Since we'll skip resetting the plane for a pageflip we will no longer
grab the DRM private object for pageflips as well, avoiding the
page fault issued caused by pageflipping under load with commits
executing out of order.

Nicholas Kazlauskas dc4cb30dee drm/amd/display: Reset plane for anything that's not a FAST update
[Why]
MEDIUM or FULL updates can require global validation or affect
bandwidth. By treating these all simply as surface updates we aren't
actually passing this through DC global validation.

[How]
There's currently no way to pass surface updates through DC global
validation, nor do I think it's a good idea to change the interface
to accept these.

DC global validation itself is currently stateless, and we can move
our update type checking to be stateless as well by duplicating DC
surface checks in DM based on DRM properties.

We wanted to rely on DC automatically determining this since DC knows
best, but DM is ultimately what fills in everything into DC plane
state so it does need to know as well.

There are basically only three paths that we exercise in DM today:

1) Cursor (async update)
2) Pageflip (fast update)
3) Full pipe programming (medium/full updates)

Which means that anything that's more than a pageflip really needs to
go down path #3.

So this change duplicates all the surface update checks based on DRM
state instead inside of should_reset_plane().

Next step is dropping dm_determine_update_type_for_commit and we no
longer require the old DC state at all for global validation.

Optimization can come later so we don't reset DC planes at all for
MEDIUM udpates and avoid validation, but we might require some extra
checks in DM to achieve this.

[Why]
We're racing with userspace as the flags could potentially change

We unfortunately can't drop this function in its entirety from

Nicholas Kazlauskas 9a81cc6079 drm/amd/display: Reset plane when tiling flags change
[Why]
Enabling or disable DCC or switching between tiled and linear formats
can require bandwidth updates.

They're currently skipping all DC validation by being treated as purely
surface updates.

[How]
Treat tiling_flag changes (which encode DCC state) as a condition for
resetting the plane.

Nicholas Kazlauskas 707477b086 drm/amd/display: Store tiling_flags and tmz_surface on dm_plane_state
[Why]
Store these in advance so we can reuse them later in commit_tail without
having to reserve the fbo again.

These will also be used for checking for tiling changes when deciding
to reset the plane or not.

[How]
This change should mostly be a refactor. Only commit check is affected
for now and I'll drop the get_fb_info calls in prepare_planes and
commit_tail after.

This runs a prepass loop once we think that all planes have been added
to the context and replaces the get_fb_info calls with accessing the
dm_plane_state instead.

Alvin Lee 4453fbec10 drm/amd/display: Separate pipe disconnect from rest of progrmaming
[Why]
When changing pixel formats for HDR (e.g. ARGB -> FP16)
there are configurations that change from 2 pipes to 1 pipe.
In these cases, it seems that disconnecting MPCC and doing
a surface update at the same time(after unlocking) causes
some registers to be updated slightly faster than others
after unlocking (e.g. if the pixel format is updated to FP16
before the new surface address is programmed, we get
corruption on the screen because the pixel formats aren't
matching). We separate disconnecting MPCC from the rest
of  the  pipe programming sequence to prevent this.

[How]
Move MPCC disconnect into separate operation than the
rest of the pipe programming.

Trying to grab dma_resv_lock while in commit_tail before we've done
all the code that leads to the eventual signalling of the vblank event
(which can be a dma_fence) is deadlock-y. Don't do that.

Here the solution is easy because just grabbing locks to read
something races anyway. We don't need to bother, READ_ONCE is
equivalent. And avoids the locking issue.

v2: Also take into account tmz_surface boolean, plus just delete the
old code.

Mazin Rezk 7619517598 drm/amd/display: Clear dm_state for fast updates
This patch fixes a race condition that causes a use-after-free during
amdgpu_dm_atomic_commit_tail. This can occur when 2 non-blocking commits
are requested and the second one finishes before the first. Essentially,
this bug occurs when the following sequence of events happens:

1. Non-blocking commit #1 is requested w/ a new dm_state #1 and is
deferred to the workqueue.

2. Non-blocking commit #2 is requested w/ a new dm_state #2 and is
deferred to the workqueue.

3. Commit #2 starts before commit #1, dm_state #1 is used in the
commit_tail and commit #2 completes, freeing dm_state #1.

4. Commit #1 starts after commit #2 completes, uses the freed dm_state
1 and dereferences a freelist pointer while setting the context.

Since this bug has only been spotted with fast commits, this patch fixes
the bug by clearing the dm_state instead of using the old dc_state for
fast updates. In addition, since dm_state is only used for its dc_state
and amdgpu_dm_atomic_commit_tail will retain the dc_state if none is found,
removing the dm_state should not have any consequences in fast updates.

This use-after-free bug has existed for a while now, but only caused a
noticeable issue starting from 5.7-rc1 due to 3202fa62f ("slub: relocate
freelist pointer to middle of object") moving the freelist pointer from
dm_state->base (which was unused) to dm_state->context (which is
dereferenced).

hersen wu 31f34d19f8 drm/amd/display: dchubbub p-state warning during surface planes switch
[Why]
ramp_up_dispclk_with_dpp is to change dispclk, dppclk and dprefclk
according to bandwidth requirement. call stack: rv1_update_clocks -->
update_clocks --> dcn10_prepare_bandwidth / dcn10_optimize_bandwidth
--> prepare_bandwidth / optimize_bandwidth. before change dcn hw,
prepare_bandwidth will be called first to allow enough clock,
watermark for change, after end of dcn hw change, optimize_bandwidth
is executed to lower clock to save power for new dcn hw settings.

below is sequence of commit_planes_for_stream:
step 1: prepare_bandwidth - raise clock to have enough bandwidth
step 2: lock_doublebuffer_enable
step 3: pipe_control_lock(true) - make dchubp register change will
not take effect right way
step 4: apply_ctx_for_surface - program dchubp
step 5: pipe_control_lock(false) - dchubp register change take effect
step 6: optimize_bandwidth --> dc_post_update_surfaces_to_stream
for full_date, optimize clock to save power

at end of step 1, dcn clocks (dprefclk, dispclk, dppclk) may be
changed for new dchubp configuration. but real dcn hub dchubps are
still running with old configuration until end of step 5. this need
clocks settings at step 1 should not less than that before step 1.
this is checked by two conditions: 1. if (should_set_clock(safe_to_lower
, new_clocks->dispclk_khz, clk_mgr_base->clks.dispclk_khz) ||
new_clocks->dispclk_khz == clk_mgr_base->clks.dispclk_khz)
2. request_dpp_div = new_clocks->dispclk_khz > new_clocks->dppclk_khz

the second condition is based on new dchubp configuration. dppclk
for new dchubp may be different from dppclk before step 1.
for example, before step 1, dchubps are as below:
pipe 0: recout=(0,40,1920,980) viewport=(0,0,1920,979)
pipe 1: recout=(0,0,1920,1080) viewport=(0,0,1920,1080)
for dppclk for pipe0 need dppclk = dispclk

new dchubp pipe split configuration:
pipe 0: recout=(0,0,960,1080) viewport=(0,0,960,1080)
pipe 1: recout=(960,0,960,1080) viewport=(960,0,960,1080)
dppclk only needs dppclk = dispclk /2.

dispclk, dppclk are not lock by otg master lock. they take effect
after step 1. during this transition, dispclk are the same, but
dppclk is changed to half of previous clock for old dchubp
configuration between step 1 and step 6. This may cause p-state
warning intermittently.

[How]
for new_clocks->dispclk_khz == clk_mgr_base->clks.dispclk_khz, we
need make sure dppclk are not changed to less between step 1 and 6.
for new_clocks->dispclk_khz > clk_mgr_base->clks.dispclk_khz,
new display clock is raised, but we do not know ratio of
new_clocks->dispclk_khz and clk_mgr_base->clks.dispclk_khz,
new_clocks->dispclk_khz /2 does not guarantee equal or higher than
old dppclk. we could ignore power saving different between
dppclk = displck and dppclk = dispclk / 2 between step 1 and step 6.
as long as safe_to_lower = false, set dpclk = dispclk to simplify
condition check.

Jun Lei 9b6ca29e09 drm/amd/display: Disable idle optimizations before programming DCN
[Why]
Programming DCN is explicitly forbidden during idle optimzations allowed
state. Existing implemenation relies on OS/DM, which is not robust. Instead
DC should sequence this.

Note that DC will not re-enter idle optimized state on its own, it is only
responsible for catching out of sequence calls. It is still DM
responsibility to sequence appropriate for optimized power, but this change
removes the requirement for DM to cover the .1% case.

[How]
 - elevate updates during idle optimized state to full updates
 - disable idle power optimizations prior to programming

Stylon Wang 473e2d1677 drm/amd/display: Fix dmesg warning from setting abm level
[Why]
Setting abm level does not correctly update CRTC state. As a result
no surface update is added to dc stream state and triggers warning.

[How]
Correctly update CRTC state when setting abm level property.

Mazin Rezk fde9f39ac7 drm/amd/display: Clear dm_state for fast updates
This patch fixes a race condition that causes a use-after-free during
amdgpu_dm_atomic_commit_tail. This can occur when 2 non-blocking commits
are requested and the second one finishes before the first. Essentially,
this bug occurs when the following sequence of events happens:

1. Non-blocking commit #1 is requested w/ a new dm_state #1 and is
deferred to the workqueue.

2. Non-blocking commit #2 is requested w/ a new dm_state #2 and is
deferred to the workqueue.

3. Commit #2 starts before commit #1, dm_state #1 is used in the
commit_tail and commit #2 completes, freeing dm_state #1.

4. Commit #1 starts after commit #2 completes, uses the freed dm_state
1 and dereferences a freelist pointer while setting the context.

Since this bug has only been spotted with fast commits, this patch fixes
the bug by clearing the dm_state instead of using the old dc_state for
fast updates. In addition, since dm_state is only used for its dc_state
and amdgpu_dm_atomic_commit_tail will retain the dc_state if none is found,
removing the dm_state should not have any consequences in fast updates.

This use-after-free bug has existed for a while now, but only caused a
noticeable issue starting from 5.7-rc1 due to 3202fa62f ("slub: relocate
freelist pointer to middle of object") moving the freelist pointer from
dm_state->base (which was unused) to dm_state->context (which is
dereferenced).

Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=207383
Fixes: bd200d190f ("drm/amd/display: Don't replace the dc_state for fast updates")

[Why]
In dcn3_update_clocks there are situations where dppclk is not
lowered (i.e. stays the same), but DTO still needs to be increased
before we program pipe frontend (i.e. in prepare_bandwidth). If we
don't program the new DTO value before we program the pipe,
we will underflow as soon as the pipe lock is released until the
next call to dcn3_update_clocks where the DTO is updated.

[How]
Remove dppclk check before programming new DTO value.

Dennis Li df9c8d1aa2 drm/amdgpu: fix system hang issue during GPU reset
when GPU hang, driver has multi-paths to enter amdgpu_device_gpu_recover,
the atomic adev->in_gpu_reset and hive->in_reset are used to avoid
re-entering GPU recovery.

During GPU reset and resume, it is unsafe that other threads access GPU,
which maybe cause GPU reset failed. Therefore the new rw_semaphore
adev->reset_sem is introduced, which protect GPU from being accessed by
external threads during recovery.

v2:
1. add rwlock for some ioctls, debugfs and file-close function.
2. change to use dqm->is_resetting and dqm_lock for protection in kfd
driver.
3. remove try_lock and change adev->in_gpu_reset as atomic, to avoid
re-enter GPU recovery for the same GPU hang.

v3:
1. change back to use adev->reset_sem to protect kfd callback
functions, because dqm_lock couldn't protect all codes, for example:
free_mqd must be called outside of dqm_lock;

As both VRR min and max are already part of drm_display_info,
drm can expose this VRR range for each connector.

Hence this logic should move to core DRM.

Nicholas Kazlauskas 8fe684e97c drm/amd/display: Allow for vblank enabled with no active planes
[Why]
CRC capture doesn't work when the active plane count is 0 since we
currently tie both vblank and pageflip interrupts to active_plane_count
greater than 0.

[How]
The frontend is what generates the vblank interrupts while the backend
is what generates pageflip interrupts. Both have a requirement for
the CRTC to be active, so control the overall interrupt state based
on that instead.

Pageflip interrupts need to be enabled based on active plane count, but
we actually rely on power gating to take care of disabling the interrupt
for us on pipes that can be power gated.

For pipes that can't be power gated it's still fine to leave it enabled
since the interrupt only triggers after the address has been written
to that particular pipe - which we won't be doing without an active
plane.

The issue we had before with this setup was that we couldn't force
the state back on. We were essentially manipulating the refcount
to enable or disable as needed in a two pass approach.

However, there is a function that solves this problem more elegantly:
amdgpu_irq_update() will unconditionally call the set based on what it
thinks the current enablement state is.

This leaves two future TODO items for our IRQ handling:
- Disabling IRQs in commit tail instead of atomic commit
- Mapping the pageflip interrupt to VUPDATE or something that's tied to
  the frontend instead of the backend since the mapping to CRTC is not
  correct

hersen wu 1f9ce3cf18 drm/amd/display: p-state warning occurs while changing resolution from 120hz to 60hz
[Why]
new calculated dispclk, dppclk are stored in
context->bw_ctx.bw.dcn.clk.dispclk_khz, dppclk_khz. Current dispclk,
dppclk are from dc->clk_mgr->clks.dispclk_khz. dcn_validate_bandwidth
compute new dispclk, dppclk. dispclk will put in use after
optimize_bandwidth when ramp_up_dispclk_with_dpp is called. There are
two places for dppclk be put in use. One location is the same as the
location as dispclk. Another is within update_dchubp_dpp which happens
between pre_bandwidth and optimize_bandwidth. dppclk updated within
update_dchubp_dpp will cause new clock values of dispclk and dppclk not
be in use at the same time. when clocks are decreased, this may cause
dppclk is lower than current configuration and let pipe stuck. for
example, eDP + external dp, change resolution of DP from 1920x1080x144hz
to 1280x960x60hz.

before change: dispclk = 337889 dppclk = 337889
change mode, dcn_validate_bandwidth calculate
             dispclk = 143122 dppclk = 143122
update_dchubp_dpp be executed before dispclk be updated,
dispclk = 337889, but dppclk use new value dispclk /2 =
168944. this will cause pipe pstate warning issue.

[How]
between pre_bandwidth and optimize_bandwidth, while dispclk is going to
be decreased, keep dppclk = dispclk

Nicholas Kazlauskas 33d63b1f4d drm/amd/display: Only revalidate bandwidth on medium and fast updates
[Why]
Changes that are fast don't require updating DLG parameters making
this call unnecessary. Considering this is an expensive call it should
not be done on every flip.

DML touches clocks, p-state support, DLG params and a few other DC
internal flags and these aren't expected during fast. A hang has been
reported with this change when called on every flip which suggests that
modifying these fields is not recommended behavior on fast updates.

[How]
Guard the validation to only happen if update type isn't FAST.

Nicholas Kazlauskas dc43d9583f drm/amd/display: Fill in dmub_srv fw_version from firmware metadata
[Why]
DMCUB firmware version is now available from firmware metadata block.

We should be passing this into dmub_srv so we can know when to apply
firmware version specific functionality like using CW4 only instead
of the REGION4.

[How]
We don't have the helpers for DM to actually extract out firmware
metadata block themselves.

We could add that and add helpers in DM to grab this, but not every
creation sequence has firmware instruction before dmub_srv_create.

Easiest way to handle this is to fill this in automatically per DM in
the place we do have it - when calculating the region parameters. But
only fill it in if DM already hasn't in case we need to override with
a specific version.

We aren't do anything firmware version specific in dmub_srv_create
today that does require fw_version, so while it's a little unituitive
to do it when calculating region parameters it works for now.

Chris Park f8b9f9a599 drm/amd/display: Force ODM combine on 5K+ 420 modes
[Why]
All YCbCr420 resolutions 5K and above have tiling and discoloration
issues.  The issue can be remedied by forcing ODM combine from 5K to 8K.
10K resolution requires ODM 4:1.  The mechanism of what the real problem
is, that is inherent in ODM combine programming, doesn't seem to be
pointed at singular register programming (CLK, MPC, DCSURF, etc.), and
needs more in-depth programming sequence review for these new use case
scenarios.  Until then, workaround to enable ODM combine is proposed.
While it is not our policy, HW spreadsheet also recommends turning on
ODM for these scenario to lower the voltage.

If optimized init is done in FW. DCN init be skipped in driver. This
need to be communicated between driver and fw and maintain backwards
compatibility.

[How]
Use DMUB scratch 0 bit 2 to indicate optimized init done in fw and
use DMUB scatch 4 bit 0 to indicate drive supports the optimized flow
so FW will perform it.

Aurabindo Pillai 8c44515be1 drm/amd/display: clip plane rects in DM before passing into DC
[Why]
DC global validation can fail when userspace requests to draw large
plane without performing the clipping themselves.

This is observed in the IGT kms_plane panning tests for 4K displays
where they draw an 8K plane without any clipping while expecting only
the top 4K to be drawn.

[How]
DRM already has helpers to take care of the clipping necessary and to
mark whether a plane is visible or not, so make use of these helpers
in DM before passing the plane to DC.

Jun Lei 0a25e8eb95 drm/amd/display: add support for per-state dummy-pstate latency
[why]
Dummy pstate latency actually varies between different
UCLK frequencies, when calculating watermark C, if DAL
always assumes worst case, then it can lead to dummy
pstate not supported scenarios.

[how]
Rather than statically calculating dummy pstate using
worst case, we store the entire table of UCLK to dummy
pstate relationships.  On a per mode basis, we calculate
the actual UCLK lower limit, and use the dynamic worst
case dummy pstate latency.  This prevents the situation
where we don't support full p-state (which will force
high DPM), but still use low DPM dummy pstate latency.

Nicholas Kazlauskas ca8e2084e5 drm/amd/display: Use u16 for drm_bpp in DSC calculations
[Why]
DSC calculations fail because the u16 bits_per_pixel from
the DRM struct is being casted to the u8 drm_bpp parameters
and locals. Integer wraparound is happening because this
value is greater than 255.

[How]
Use u16 to match what's in the structure instead of u8.

Rodrigo Siqueira 1e5d05ec80 drm/amd/display: Rework dsc to isolate FPU operations
When we want to use float point operation on Linux
we need to use within special kernel protection
(`kernel_fpu_{begin,end}()`.), otherwise the kernel
can clobber userspace FPU register state. For detecting
these issues we use a tool named objtool (with -Ffa
flags) to highlight the FPU problems, all warnings can
be summed up as follows:

./tools/objtool/objtool check -Ffa
drivers/gpu/drm/amd/display/dc/dml/dml_common_defs.o

[..] dc/dsc/rc_calc.o: warning: objtool: get_qp_set()+0x2f8:

[..] dc/dsc/rc_calc_dpi.o: warning: objtool:

This commit fixes the above issues by rework DSC as described:

1. Isolate all FPU operations in a single file;
2. Use FPU flags only in the file that handles FPU operations;
3. Isolate all functions that require float point operation in static
   functions;
4. Add a mid-layer function that does not use any float point operation,
   and that could be safely invoked in other parts of the code.
5. Keep float point operation under DC_FP_{START/END} macro.

should have the proper blanking state which is either handled by either
DPG or TG depending on the hardware generation.  Check both to determine
the proper blanked state.

Nicholas Kazlauskas 4ec6c0a208 drm/amd/display: Revalidate bandwidth before commiting DC updates
[Why]
Whenever we switch between tiled formats without also switching pixel
formats or doing anything else that recreates the DC plane state we
can run into underflow or hangs since we're not updating the
DML parameters before committing to the hardware.

[How]
If the update type is FULL then call validate_bandwidth again to update
the DML parmeters before committing the state.

This is basically just a workaround and protective measure against
update types being added DC where we could run into this issue in
the future.

We can only fully validate the state in advance before applying it to
the hardware if we recreate all the plane and stream states since
we can't modify what's currently in use.

The next step is to update DM to ensure that we're creating the plane
and stream states for whatever could potentially be a full update in
DC to pre-emptively recreate the state for DC global validation.

The workaround can stay until this has been fixed in DM.

Nicholas Kazlauskas 6eb3cf2e06 drm/amd/display: Only revalidate bandwidth on medium and fast updates
[Why]
Changes that are fast don't require updating DLG parameters making
this call unnecessary. Considering this is an expensive call it should
not be done on every flip.

DML touches clocks, p-state support, DLG params and a few other DC
internal flags and these aren't expected during fast. A hang has been
reported with this change when called on every flip which suggests that
modifying these fields is not recommended behavior on fast updates.

[How]
Guard the validation to only happen if update type isn't FAST.

Rodrigo Siqueira 9ec051bf44 drm/amd/display: Rework dsc to isolate FPU operations
When we want to use float point operation on Linux
we need to use within special kernel protection
(`kernel_fpu_{begin,end}()`.), otherwise the kernel
can clobber userspace FPU register state. For detecting
these issues we use a tool named objtool (with -Ffa
flags) to highlight the FPU problems, all warnings can
be summed up as follows:

./tools/objtool/objtool check -Ffa
drivers/gpu/drm/amd/display/dc/dml/dml_common_defs.o

[..] dc/dsc/rc_calc.o: warning: objtool: get_qp_set()+0x2f8:

[..] dc/dsc/rc_calc_dpi.o: warning: objtool:

This commit fixes the above issues by rework DSC as described:

1. Isolate all FPU operations in a single file;
2. Use FPU flags only in the file that handles FPU operations;
3. Isolate all functions that require float point operation in static
   functions;
4. Add a mid-layer function that does not use any float point operation,
   and that could be safely invoked in other parts of the code.
5. Keep float point operation under DC_FP_{START/END} macro.

Nicholas Kazlauskas a24eaa5c51 drm/amd/display: Revalidate bandwidth before commiting DC updates
[Why]
Whenever we switch between tiled formats without also switching pixel
formats or doing anything else that recreates the DC plane state we
can run into underflow or hangs since we're not updating the
DML parameters before committing to the hardware.

[How]
If the update type is FULL then call validate_bandwidth again to update
the DML parmeters before committing the state.

This is basically just a workaround and protective measure against
update types being added DC where we could run into this issue in
the future.

We can only fully validate the state in advance before applying it to
the hardware if we recreate all the plane and stream states since
we can't modify what's currently in use.

The next step is to update DM to ensure that we're creating the plane
and stream states for whatever could potentially be a full update in
DC to pre-emptively recreate the state for DC global validation.

The workaround can stay until this has been fixed in DM.

Alex Deucher b7f839d292 drm/amdgpu/display: use blanked rather than plane state for sync groups
We may end up with no planes set yet, depending on the ordering, but we
should have the proper blanking state which is either handled by either
DPG or TG depending on the hardware generation.  Check both to determine
the proper blanked state.

0xF which is outside the size of the OPP array causing a potential

there's no OPP assigned already, then OTG will be blank anyways so no

Nicholas Kazlauskas 1aad707819 drm/amd/display: Make BREAK_TO_DEBUGGER() a debug print
[Why]
Warnings in the kernel are generally treated as errors.

The BREAK_TO_DEBUGGER macro is not a critical error or warning, but
rather intended for developer use to help investigate behavior and
sequences for other issues.

We do still make use of DC_ERROR/ASSERT(0) in various places in the
code for things that are genuine issues.

Since most developers don't actually KGDB while debugging the kernel
these essentially would have no value on their own since the KGDB
breakpoint wouldn't trigger - ASSERT(0) was used as a shortcut to get
a stacktrace.

[How]
Turn it into a DRM_DEBUG_DRIVER print instead. We unfortunately lose
the stacktrace, but we still do retain some of the useful debug
information this offers by having at least the function and line
number loggable.

If KGDB is supported in the kernel this will still trigger a real
breakpoint as well.

Wenjing Liu fb8cf277b1 drm/amd/display: DP link layer test 4.2.1.1 fix due to specs update
[why]
DP link layer CTS specs updated to change the test parameters in test
4.2.1.1.
Before it requires source to delay 400us on aux no reply.
With the specs updates Errata5, it requires source to delay 3.2ms
(based on LTTPR aux timeout)
This causes our test to fail after updating with the latest test
equipment firmware.

[how]
the change is to allow LTTPR 3.2ms aux timeout delay by default.
And only set to 400us if LTTPR is not present.
Before this piece of logic is interwined with LTTPR support.
Now we will default to 3.2ms aux timeout even if LTTPR support is not
enabled by driver.

Wyatt Wood 1db1469592 drm/amd/display: Fix ABM memory alignment issue
[Why]
Due to packing of abm_config_table, memory addresses aren't aligned to
32 bit boundary dmcub prefers.  Therefore when using pointers to this
structure, it's possible that dmcub will automatically align the data
read from that address, yielding incorrect values.

[How]
Instead of packing 1 byte boundary, explicitly pack values to 4 byte
boundary. Since there is a dependency on the existing iram table
structure on driver side, we must copy to a second structure, which is
aligned correctly, before passing to fw.

Sung Lee 65f9ace4ac drm/amd/display: Do not fail if build scaling params fails
[WHY]
Failing validation when building scaling parameters causes corruption to

This needs to fail silently for now to hide the corruption until the

Bhawanpreet Lakha cdaae8371a drm/amd/display: Handle GPU reset for DC block
[Why]
Previously we used the s3 codepath for gpu reset. This can lead to issues in
certain case where we end of waiting for fences which will never come (because
parts of the hw are off due to gpu reset) and we end up waiting forever causing
a deadlock.

[How]
Handle GPU reset separately from normal s3 case. We essentially need to redo
everything we do in s3, but avoid any drm calls.

For GPU reset case

suspend:
	-Acquire DC lock
	-Cache current dc_state
	-Commit 0 stream/planes to dc (this puts dc into a state where it can be
	 powered off)
	-Disable interrupts
resume
	-Edit cached state to force full update
	-Commit cached state from suspend
	-Build stream and plane updates from the cached state
	-Commit stream/plane updates
	-Enable interrupts
	-Release DC lock

v2:
-Formatting
-Release dc_state

Nicholas Kazlauskas b6dbb8ff9d drm/amd/display: Avoid pipe split when plane is too small
[Why]
The minimum plane size we can support in DML is 16x16. If we try to pass
a 16x16 plane with dynamic pipe split then validation will fail since it
tries to split it into two pipes, each 8x8.

Some userspace doesn't check that the commit fails and because the
commit fails the old state is retained, resulting in corruption.

[How]
Add a workaround to avoid pipe split if any plane is 16x16 or smaller.

Nicholas Kazlauskas 63731e73da drm/amd/display: Defer cursor lock until after VUPDATE
[Why]
We dropped the delay after changed the cursor functions locking the
entire pipe to locking just the CURSOR registers to fix page flip
stuttering - this introduced cursor stuttering instead, and an underflow
issue.

The cursor update can be delayed indefinitely if the cursor update
repeatedly happens right around VUPDATE.

The underflow issue can happen if we do a viewport update on a pipe
on the same frame where a cursor update happens around VUPDATE - the
old cursor registers are retained which can be in an invalid position.

This can cause a pipe hang and indefinite underflow.

[How]
The complex, ideal solution to the problem would be a software
triple buffering mechanism from the DM layer to program only one cursor
update per frame just before VUPDATE.

The simple workaround until we have that infrastructure in place is
this change - bring back the delay until VUPDATE before locking, but
with some corrections to the calculations.

This didn't work for all timings before because the calculation for
VUPDATE was wrong - it was using the offset from VSTARTUP instead and
didn't correctly handle the case where VUPDATE could be in the back
porch.

Add a new hardware sequencer function to use the existing helper to
calculate the real VUPDATE start and VUPDATE end - VUPDATE can last
multiple lines after all.

Change the udelay to incorporate the width of VUPDATE as well.
