[ Upstream commit c4b8394e76adba4f50a3c2696c75b214a291e24a ]
[Why]
When otg workaround is applied during clock update, otgs of
tiled display went out of sync.
[How]
To call dc_trigger_sync() after clock update to sync otgs again.

[ Upstream commit 94bbf802efd0a8f13147d6664af6e653637340a8 ]
Changing PBN calculation to be more in line with spec. We don't need to
inflate PBN_NATIVE value by the 1.006 margin, since that is already
taken care of in the get_pbn_per_slot function.

[ Upstream commit dd4e4bb28843393065eed279e869fac248d03f0f ]
[Description]
For mode programming we want to extend the prefetch as much as possible
(up to oto, or as long as we can for equ) if we're not already applying
the 60us prefetch requirement. This is to avoid intermittent underflow
issues during prefetch.
The prefetch extension is applied under the following scenarios:
1. We're in prefetch mode 1 (i.e. we don't support MCLK switch in blank)
2. We're using subvp or drr methods of p-state switch, in which case we
we don't care if prefetch takes up more of the blanking time
Mode programming typically chooses the smallest prefetch time possible
(i.e. highest bandwidth during prefetch) presumably to create margin between
p-states / c-states that happen in vblank and prefetch. Therefore we only
apply this prefetch extension when p-state in vblank is not required (UCLK
p-states take up the most vblank time).

[ Upstream commit 9a902a9073c287353e25913c0761bfed49d75a88 ]
[Description]
- When we're in a no plane config, DCN is always asserting
P-State allow
- This creates a scenario where the P-State blackout can start
just as VUPDATE takes place and transitions the DCN config to
a one where one or more HUBP's are active which can result in
underflow
- To fix this issue, force p-state disallow and unforce after
the transition from no planes case -> one or more planes active

[ Upstream commit bd33bb1409b494558a2935f7bbc7842def957fcd ]
MES provides the driver a call to explicitly flush stale process memory
within the MES to avoid a race condition that results in a fatal
memory violation.
When SET_SHADER_DEBUGGER is called, the driver passes a memory address
that represents a process context address MES uses to keep track of
future per-process calls.
Normally, MES will purge its process context list when the last queue
has been removed. The driver, however, can call SET_SHADER_DEBUGGER
regardless of whether a queue has been added or not.
If SET_SHADER_DEBUGGER has been called with no queues as the last call
prior to process termination, the passed process context address will
still reside within MES.
On a new process call to SET_SHADER_DEBUGGER, the driver may end up
passing an identical process context address value (based on per-process
gpu memory address) to MES but is now pointing to a new allocated buffer
object during KFD process creation. Since the MES is unaware of this,
access of the passed address points to the stale object within MES and
triggers a fatal memory violation.
The solution is for KFD to explicitly flush the process context address
from MES on process termination.
Note that the flush call and the MES debugger calls use the same MES
interface but are separated as KFD calls to avoid conflicting with each
other.

Issue: during evict or validate happened on amdgpu_bo, the 'from' and
'to' is always same in ftrace event of amdgpu_bo_move
where calling the 'trace_amdgpu_bo_move', the comment says move_notify
is called before move happens, but actually it is called after move
happens, here the new_mem is same as bo->resource
Fix: move trace_amdgpu_bo_move from move_notify to amdgpu_bo_move

This variable currently overflows after about 71 minutes. This doesn't
cause any known functional issues but it does make debugging more
difficult.
[How]
Make it a 64-bit variable.

[ Upstream commit dff45f03f508c92cd8eb2050e27b726726b8ae0b ]
[Description]
There is a corner case where the symclk otg flag is cleared
when disabling the phantom pipe for subvp (because the phantom
and main pipe share the same link). This is undesired because
we need the maintain the correct symclk otg flag state for
the main pipe.
For now only clear the flag only for HDMI signal type, since
it's only set for HDMI signal type (phantom is virtual). The
ideal solution is to not clear it if the stream is phantom but
currently there's a bug that doesn't allow us to do this. Once
this issue is fixed the proper fix can be implemented.

From: "Stanley.Yang" <Stanley.Yang@amd.com>
[ Upstream commit a32c6f7f5737cc7e31cd7ad5133f0d96fca12ea6 ]
The ecc_irq is disabled while GPU mode2 reset suspending process,
but not be enabled during GPU mode2 reset resume process.
Changed from V1:
only do sdma/gfx ras_late_init in aldebaran_mode2_restore_ip
delete amdgpu_ras_late_resume function
Changed from V2:
check umc ras supported before put ecc_irq

[ Upstream commit aa5dc05340eb97486a631ce6bccb8d020bf6b56b ]
[Why]
Fix minor issues in BW Allocation Phase2.
[How]
- In set_usb4_req_bw_req(), link->dpia_bw_alloc_config.response_ready
flag should be reset before writing DPCD REQUEST_BW.
- Fix the granularity for value of 2 in get_bw_granularity().
- Removed bandwidth allocation support display fw boot option as
the fw would read feature enable status from bios.
- Clean up DPIA_EST_BW_CHANGED and DPIA_BW_REQ_SUCCESS cases in
dpia_handle_bw_alloc_response().
- Removed allocate_usb4_bw and deallocate_usb4_bw.
- Optimized loop in get_lowest_dpia_index().
- Updated link_dp_dpia_allocate_usb4_bandwidth_for_stream() and
set_usb4_req_bw_req() to always issue request bw.

[ Upstream commit ec9ba4821fa52b5efdbc4cdf0a77497990655231 ]
Change the rules for amdgpu_sync_resv to let KFD synchronize with VM
fences on page table reservations. This fixes intermittent memory
corruption after evictions when using amdgpu_vm_handle_moved to update
page tables for VM mappings managed through render nodes.

For certain dual display configs that had one display using a 1080p
mode, the DPM level used to drive the configs regressed from DPM 0 to
DPM 3. This was caused by a missing check that should have only limited
the pipe segments on non-phantom pipes. This caused issues with detile
buffer allocation, which dissallow subvp from being used

[ Upstream commit d6398866a6b47e92319ef6efdb0126a4fbb7796a ]
This reverts commit 44e60b14d5a72f91fd0bdeae8da59ae37a3ca8e5.
Since, it causes a regression in which eDP displays with PSR support,
but no Replay support (Sink support <= 0x03), fail to enable PSR and
consequently all IGT amd_psr tests fail. So, revert this until a more
suitable fix can be found.
This got brought back accidently with the backmerge.

[ Upstream commit 0f35b0a7b8fa402adbffa2565047cdcc4c480153 ]
That commit causes NULL pointer dereferences in dmesgs when
running applications using ROCm, including clinfo, blender,
and PyTorch, since v6.6.1. Revert it to fix blender again.
This reverts commit 96c211f1f9ef82183493f4ceed4e347b52849149.

[ Upstream commit 16783d8ef08448815e149e40c82fc1e1fc41ddbf ]
These chips needs the same fix. This was previously not seen
on then since the AGP aperture expanded the system aperture,
but this showed up again when AGP was disabled.
