07944623c7 drm/amdgpu: access register without KIQ
There is no need to access register such as mmSMC_IND_INDEX_11
and mmSMC_IND_DATA_11, PCIE_INDEX, PCIE_DATA through KIQ because
they are VF-copy.

674e78acae drm/amd/display: Add fast path for cursor plane updates
[Why]
Legacy cursor plane updates from drm helpers go through the full
atomic codepath. A high volume of cursor updates through this slow
code path can cause subsequent page-flips to skip vblank intervals
since each individual update is slow.

This problem is particularly noticeable for the compton compositor.

[How]
A fast path for cursor plane updates is added by using DRM asynchronous
commit support provided by async_check and async_update. These don't do
a full state/flip_done dependency stall and they don't block other
commit work.

However, DC still expects itself to be single-threaded for anything
that can issue register writes. Screen corruption or hangs can occur
if write sequences overlap. Every call that potentially perform
register writes needs to be guarded for asynchronous updates to work.
The dc_lock mutex was added for this.

922454c2e7 drm/amd/display: Fix duplicating scaling/underscan connector state
[Why]
These properties aren't being carried over when the atomic state.
This tricks atomic check and commit tail into performing underscan
and scaling operations when they aren't needed.

With the patch that forced scaling/RMX_ASPECT on by default this
results in many unnecessary surface updates and hangs under certain
conditions.

[How]
Duplicate the properties.

65276f2beb drm/amd/display: Fix unintialized max_bpc state values
[Why]
If the "max bpc" isn't explicitly set in the atomic state then it
have a value of 0. This has the correct behavior of limiting a panel
to 8bpc in the case where the panel supports 8bpc. In the case of eDP
panels this isn't a true assumption - there are panels that can only
do 6bpc.

Banding occurs for these displays.

[How]
Initialize the max_bpc when the connector resets to 8bpc. Also carry
over the value when the state is duplicated.

28c5946930 Revert "drm/amd/display: Set RMX_ASPECT as default"
This reverts commit 91b66c47ba.

Forcing RMX_ASPECT as default uses the preferred/native mode's timings
for any mode the user selects and scales the image. This provides a
a consistently nicer result in the case where the selected mode's
refresh rate matches the native mode's refresh but this isn't always
the case.

For example, if the monitor is 1080p@144Hz and the preferred mode is
60Hz then even if the user selects 1080p@144Hz as their selected mode
they'll get 1080p@60Hz.

9ed9203c3e drm/amd/powerplay: rv dal-pplib interface refactor powerplay part
[WHY] clarify dal input parameters to pplib interface, remove
un-used parameters. dal knows exactly which parameters needed
and their effects at pplib and smu sides.

current dal sequence for dcn1_update_clock to pplib:

1.smu10_display_clock_voltage_request for dcefclk
2.smu10_display_clock_voltage_request for fclk
3.phm_store_dal_configuration_data {
  set_min_deep_sleep_dcfclk
  set_active_display_count
  store_cc6_data --- this data never be referenced

new sequence will be:

1. set_display_count  --- need add new pplib interface
2. set_min_deep_sleep_dcfclk -- new pplib interface
3. set_hard_min_dcfclk_by_freq
4. set_hard_min_fclk_by_freq

after this code refactor, smu10_display_clock_voltage_request,
phm_store_dal_configuration_data will not be needed for rv.

[HOW] step 1: add new functions at pplib interface
      step 2: add new functions at amdgpu dm and dc

Tracing is a useful and cheap debug functionality

[How]
This creates a new trace system amdgpu_dm, currently with
three trace events

amdgpu_dc_rreg and amdgpu_dc_wreg report the address and value
of any dc register reads and writes

amdgpu_dc_performance requires at least one of those two to be
enabled.  It counts the register reads and writes since the
last entry

090afc1e40 drm/amd/display: Fix overflow/truncation from strncpy.
[Why]

New GCC warnings for stringop-truncation and stringop-overflow help
catch common misuse of strncpy. This patch suppresses these warnings
by fixing bugs identified by them.

[How]

Since the parameter passed for name in amdpgu_dm_create_common_mode has
no fixed length, if the string is >= DRM_DISPLAY_MODE_LEN then
mode->name will not be null-terminated.

The truncation in fill_audio_info won't actually occur (and the string
will be null-terminated since the buffer is initialized to zero), but
the warning can be suppressed by using the proper buffer size.

This patch fixes both issues by using the real size for the buffer and
making use of strscpy (which always terminates).

2119aa17c9 drm/amd/display: Start documentation of DC
[Why]
There are a lot of unintuitive parts of the dm-dc interface.
It would help us if these were documented to provide
a common understanding of what they are supposed to do

[How]
Most of this documentation is stubs, to be filled out more
thoroughly by the experts

Not every dm-accessible function and struct is mentioned.
Simple functions like getters, setters, retain, release,
create, destroy can be left unadorned.

50f9ca048c drm/amd/display: fix sporadic multiple aux transaction failure
[why]
When there are multiple aux transaction in parallel, it is sometime
sporadically the aux transaction starts to continuously fail. The
aux transaction was failing because the busy bit for the given gpio
pin was always set. The busy bit was alway set because the
programming sequence to read, modify and write busy bit was not
atomic. Due to which when multiple threads are trying to modify the
busy bits for their gpio pins in the same integer variable sometimes
the busy bits integer variable is written with old data causing
failure.

[how]
Instead of using individual bits to track gpio pins and grouping
them to integers, one byte will be allcoated for each gpio pin.
Now whenever a gpio pin needs to be set to mark being used, only
writing a value of one to that byte is sufficient, other bytes
are not impacted. Also no need to have atomicity with bytes unlike
with bits.

49f1c44b58 drm/amd/display: Fix unintialized max_bpc state values
[Why]
If the "max bpc" isn't explicitly set in the atomic state then it
have a value of 0. This has the correct behavior of limiting a panel
to 8bpc in the case where the panel supports 8bpc. In the case of eDP
panels this isn't a true assumption - there are panels that can only
do 6bpc.

Banding occurs for these displays.

[How]
Initialize the max_bpc when the connector resets to 8bpc. Also carry
over the value when the state is duplicated.

26bc534094 drm/amdgpu: Refactor GPU reset for XGMI hive case
For XGMI hive case do reset in steps where each step iterates over
all devs in hive. This especially important for asic reset
since all PSP FW in hive must come up within a limited time
(around 1 sec) to properply negotiate the link.
Do this by  refactoring  amdgpu_device_gpu_recover and amdgpu_device_reset
into pre_asic_reset, asic_reset and post_asic_reset functions where is part
is exectued for all the GPUs in the hive before going to the next step.

v2: Update names for amdgpu_device_lock/unlock functions.

v3: Introduce per hive locking to avoid multiple resets for GPUs
    in same hive.
v4:
Remove delayed_workqueue()/ttm_bo_unlock_delayed_workqueue() - they
are copy & pasted over from radeon and on amdgpu there isn't
any reason for that any more.

bb47de7366 drm/amdgpu: Set FreeSync state using drm VRR properties
Support for AMDGPU specific FreeSync properties and ioctls are dropped
from amdgpu_dm in favor of supporting drm variable refresh rate
properties.

The notify_freesync and set_freesync_property functions are dropped
from amdgpu_display_funcs.

The drm vrr_capable property is now attached to any DP/HDMI connector.
Its value is updated accordingly to the connector's FreeSync capabiltiy.

The freesync_enable logic and ioctl control has has been dropped in
favor of utilizing the vrr_enabled on the drm CRTC. This allows for more
fine grained atomic control over which CRTCs should support variable
refresh rate.

To handle state changes for vrr_enabled it was easiest to drop the
forced modeset on freesync_enabled change. This patch now performs the
required stream updates when planes are flipped.

This is done for a few reasons:

(1) VRR stream updates can be done in the fast update path

(2) amdgpu_dm_atomic_check would need to be hacked apart to check
    desired variable refresh state and capability before the CRTC
    disable pass.

(3) Performing VRR stream updates on-flip is needed for enabling BTR
    support.

VRR packets and timing adjustments are now tracked and compared to
previous values sent to the hardware.

520f08df45 drm/amdgpu: Correct get_crtc_scanoutpos behavior when vpos >= vtotal
When variable refresh rate is active the hardware counter can return
a position >= vtotal. This results in a vpos being returned from
amdgpu_display_get_crtc_scanoutpos that's a positive value. The
positive value indicates to the caller that the display is
currently in scanout when the display is actually still in vblank.

This is because the vfront porch duration is unknown with variable
refresh active and will end when either a page flip occurs or the
timeout specified by the driver/display is reached.

The behavior of the amdgpu_display_get_crtc_scanoutpos remains the
same when the position is below vtotal. When the position is above
vtotal the function will return a value that is effectively -vbl_end,
the size of the vback porch.

The only caller affected by this change is the DRM helper for
calculating vblank timestamps. This change corrects behavior for
calculating the page flip timestamp from being the previous timestamp
to the calculation to the next timestamp when position >= vtotal.

eb3dc89785 drm/amd/display: Use private obj helpers for dm_atomic_state
[Why]
Two non-blocking commits in succession can result in a sequence where
the same dc->current_state is queried for both commits.

1. 1st commit -> check -> commit -> swaps atomic state -> queues work
2. 2nd commit -> check -> commit -> swaps atomic state -> queues work
3. 1st commit work finishes

The issue with this sequence is that the same dc->current_state is
read in both atomic checks. If the first commit modifies streams or
planes those will be missing from the dc->current_state for the
second atomic check. This result in many stream and plane errors in
atomic commit tail.

[How]
The driver still needs to track old to new state to determine if the
commit in its current implementation. Updating the dc_state in
atomic tail is wrong since the dc_state swap should be happening as
part of drm_atomic_helper_swap_state *before* the worker queue kicks
its work off.

The simplest replacement for the subclassing (which doesn't properly
manage the old to new atomic state swap) is to use the drm private
object helpers. While some of the dc_state members could be merged
into dm_crtc_state or dm_plane_state and copied over that way it is
easier for now to just treat the whole dc_state structure as a single
private object.

This allows amdgpu_dm to drop the dc->current_state copy from within
atomic check. It's replaced by a copy from the current atomic state
which is propagated correctly for the sequence described above.

Since access to the dm_state private object is now locked this should
also fix issues that could arise if submitting non-blocking commits
from different threads.

ad97d9de45 drm/amdgpu: Add delay after enable RLC ucode
Driver shouldn't try to access any GFX registers until RLC is idle.
During the test, it took 12 seconds for RLC to clear the BUSY bit
in RLC_GPM_STAT register which is un-acceptable for driver.
As per RLC engineer, it would take RLC Ucode less than 10,000 GFXCLK
cycles to finish its critical section. In a lowest 300M enginer clock
setting(default from vbios), 50 us delay is enough.

This commit fix the hang when RLC introduce the work around for XGMI

c1ee92f94c drm/amd: Add abm level drm property
Adaptive Backlight Management (ABM) is a feature
that reduces backlight level to save power, while
increasing pixel contrast and pixel luminance
to maintain readability and image quality.

ABM will adjust in response to the
pixel luminance of the displayed content.

ABM is made available as a drm property on eDP
monitors called "abm level", which ranges from 0 to 4.
When this property is set to 0, ABM is off.  Levels 1
to 4 represent different ranges of backlight reduction.
At higher levels both the backlight reduction and pixel
adjustment will be greater.

ABM requires DMCU firmware, which is currently available for
Raven ASICs only.  If the feature does not work, please
ensure your firmware is up to date.

v2:
Fix commit message, only attach property if DMCU loaded
v3:
Store ABM level in crtc state to accommodate dc

DC uses memcmp to check if timing changed, in this case DC will
say timing changed and we endup doing a full modeset.

Current:
Now we check if !RMX_OFF and old_refresh == new_refresh if so
we copy the vic from old timing. In a case where we are currently on
a lower timing and want to change to higher mode, stream->dst will be
different and cause us to do a full modeset, which is what we want.

0f04e53858 drm/amdgpu: Fix KFD doorbell SG BO mapping
This change prepares for adding SG BOs that will be used for mapping
doorbells into GPUVM address space.

This type of BO would be mistaken for an invalid userptr BO. Improve
that check to test that it's actually a userptr BO so that SG BOs that
are still in the CPU domain can be validated and mapped correctly.

5aae7335b1 drm/amdkfd: Fix and simplify sync object handling for KFD
The adev parameter in amdgpu_sync_fence and amdgpu_sync_resv is only
needed for updating sync->last_vm_update. This breaks if different
adevs are passed to calls for the same sync object.

Always pass NULL for calls from KFD because sync objects used for
KFD don't belong to any particular device, and KFD doesn't need the
sync->last_vm_update fence.

This fixes kernel log warnings on multi-GPU systems after recent
changes in amdgpu_amdkfd_gpuvm_restore_process_bos.

9130cc01d1 drm/amdgpu: Remove explicit wait after VM validate
PD or PT might have to be moved during validation and this move has to be
completed before updating it. If page table updates are done using SDMA
then this serializing is done by SDMA command submission.

And if PD/PT updates are done by CPU, then explicit waiting for PD/PT
updates are done in amdgpu VM amdgpu_vm_wait_pd function.

Sync to PD BO moving fence to handle corner case where none of the PTs
are updated but PD is evicted.
