[PATCH AUTOSEL 5.13 005/189] drm/amd/display: fix HDCP reset sequence on reinitialize

[Sasha Levin]

From: Brandon Syu <Brandon.Syu@amd.com>

[ Upstream commit 99c248c41c2199bd34232ce8e729d18c4b343b64 ]

[why]
When setup is called after hdcp has already setup,
it would cause to disable HDCP flow won’t execute.

[how]
Don't clean up hdcp content to be 0.

[PATCH AUTOSEL 5.13 006/189] drm/amd/display: Revert wait vblank on update dpp clock

[Sasha Levin]

From: Lewis Huang <Lewis.Huang@amd.com>

[ Upstream commit d5433a9f692f57c814286f8af2746c567ef79fc8 ]

[Why]
This change only fix dpp clock switch to lower case.
New solution later can fix both case, which is "dc: skip
program clock when allow seamless boot"

[How]
This reverts commit "dc: wait vblank when stream enabled
and update dpp clock"

From: Jack Zhang <Jack.Zhang1@amd.com>

[ Upstream commit 95ea3dbc4e9548d35ab6fbf67675cef8c293e2f5 ]

Disable all ip's hw status to false before any hw_init.
Only set it to true until its hw_init is executed.

The old 5.9 branch has this change but somehow the 5.11 kernrel does
not have this fix.

Without this change, sriov tdr have gfx IB test fail.

[PATCH AUTOSEL 5.13 014/189] drm/amd/display: fix potential gpu reset deadlock

[Sasha Levin]

From: Roman Li <Roman.Li@amd.com>

[ Upstream commit cf8b92a75646735136053ce51107bfa8cfc23191 ]

[Why]
In gpu reset dc_lock acquired in dm_suspend().
Asynchronously handle_hpd_rx_irq can also be called
through amdgpu_dm_irq_suspend->flush_work, which also
tries to acquire dc_lock. That causes a deadlock.

[How]
Check if amdgpu executing reset before acquiring dc_lock.

[PATCH AUTOSEL 5.13 016/189] drm/amd/display: Fix clock table filling logic

[Sasha Levin]

From: Ilya Bakoulin <Ilya.Bakoulin@amd.com>

[ Upstream commit c31bef1cb1203b26f901a511a3246204cfaf8a57 ]

[Why]
Currently, the code that fills the clock table can miss filling
information about some of the higher voltage states advertised
by the SMU. This, in turn, may cause some of the higher pixel clock
modes (e.g. 8k60) to fail validation.

[How]
Fill the table with one entry per DCFCLK level instead of one entry
per FCLK level. This is needed because the maximum FCLK does not
necessarily need maximum voltage, whereas DCFCLK values from SMU
cover the full voltage range.

[PATCH AUTOSEL 5.13 017/189] drm/amd/display: fix use_max_lb flag for 420 pixel formats

[Sasha Levin]

From: Dmytro Laktyushkin <Dmytro.Laktyushkin@amd.com>

[ Upstream commit 8809a7a4afe90ad9ffb42f72154d27e7c47551ae ]

Right now the flag simply selects memory config 0 when flag is true
however 420 modes benefit more from memory config 3.

[PATCH AUTOSEL 5.13 050/189] drm/amd/display: fix odm scaling

[Sasha Levin]

From: Dmytro Laktyushkin <Dmytro.Laktyushkin@amd.com>

[ Upstream commit 6566cae7aef30da8833f1fa0eb854baf33b96676 ]

There are two issues with scaling calculations, odm recout
calculation and matching viewport to actual recout.

This change fixes both issues. Odm recout calculation via
special casing and viewport matching issue by reworking
the viewport calcualtion to use scaling ratios and recout
to derrive the required offset and size.

[PATCH AUTOSEL 5.13 068/189] drm/amd/display: Avoid HDCP over-read and corruption

[Sasha Levin]

From: Kees Cook <keescook@chromium.org>

[ Upstream commit 06888d571b513cbfc0b41949948def6cb81021b2 ]

Instead of reading the desired 5 bytes of the actual target field,
the code was reading 8. This could result in a corrupted value if the
trailing 3 bytes were non-zero, so instead use an appropriately sized
and zero-initialized bounce buffer, and read only 5 bytes before casting
to u64.

[PATCH AUTOSEL 5.13 088/189] drm/amd/display: Fix DCN 3.01 DSCCLK validation

[Sasha Levin]

From: Nikola Cornij <nikola.cornij@amd.com>

[ Upstream commit 346cf627fb27c0fea63a041cedbaa4f31784e504 ]

[why]
DSCCLK validation is not necessary because DSCCLK is derrived from
DISPCLK, therefore if DISPCLK validation passes, DSCCLK is valid, too.
Doing DSCLK validation in addition to DISPCLK leads to modes being
wrongly rejected when DSCCLK was incorrectly set outside of DML.

[how]
Remove DSCCLK validation because it's implicitly validated under DISPCLK

[PATCH AUTOSEL 5.13 090/189] drm/amd/display: Update scaling settings on modeset

[Sasha Levin]

From: Roman Li <roman.li@amd.com>

[ Upstream commit c521fc316d12fb9ea7b7680e301d673bceda922e ]

[Why]
We update scaling settings when scaling mode has been changed.
However when changing mode from native resolution the scaling mode previously
set gets ignored.

[How]
Perform scaling settings update on modeset.

[PATCH AUTOSEL 5.13 091/189] drm/amd/display: Release MST resources on switch from MST to SST

[Sasha Levin]

From: Vladimir Stempen <vladimir.stempen@amd.com>

[ Upstream commit 3f8518b60c10aa96f3efa38a967a0b4eb9211ac0 ]

[why]
When OS overrides training link training parameters
for MST device to SST mode, MST resources are not
released and leak of the resource may result crash and
incorrect MST discovery during following hot plugs.

[how]
Retaining sink object to be reused by SST link and
releasing MST  resources.

From: Aric Cyr <aric.cyr@amd.com>

[ Upstream commit 665f28507a2a3d8d72ed9afa9a2b9b17fd43add1 ]

[Why]
When calculating recout width for an MPO plane on a mode that's using
ODM combine, driver can calculate a negative value, resulting in a
crash.

[How]
For negative widths, use zero such that validation will prune the
configuration correctly and disallow MPO.

[PATCH AUTOSEL 5.13 098/189] drm/amdkfd: use allowed domain for vmbo validation

[Sasha Levin]

From: Nirmoy Das <nirmoy.das@amd.com>

[ Upstream commit bc05716d4fdd065013633602c5960a2bf1511b9c ]

Fixes handling when page tables are in system memory.

v3: remove struct amdgpu_vm_parser.
v2: remove unwanted variable.
    change amdgpu_amdkfd_validate instead of amdgpu_amdkfd_bo_validate.

[PATCH AUTOSEL 5.13 111/189] drm/amdkfd: fix circular locking on get_wave_state

[Sasha Levin]

From: Jonathan Kim <jonathan.kim@amd.com>

[ Upstream commit 63f6e01237257e7226efc5087f3f0b525d320f54 ]

get_wave_state acquires the mmap_lock on copy_to_user but so do
mmu_notifiers.  mmu_notifiers allows dqm locking so do get_wave_state
outside the dqm_lock to prevent circular locking.

v2: squash in unused variable removal.

[PATCH AUTOSEL 5.13 112/189] drm/amd/display: Cover edge-case when changing DISPCLK WDIVIDER

[Sasha Levin]

From: Wesley Chalmers <Wesley.Chalmers@amd.com>

[ Upstream commit 78ebca321999699f30ea19029726d1a3908b395f ]

[WHY]
When changing the DISPCLK_WDIVIDER value from 126 to 127, the change in
clock rate is too great for the FIFOs to handle. This can cause visible
corruption during clock change.

HW has handed down this register sequence to fix the issue.

[HOW]
The sequence, from HW:
a.	127 -> 126
Read  DIG_FIFO_CAL_AVERAGE_LEVEL
FIFO level N = DIG_FIFO_CAL_AVERAGE_LEVEL / 4
Set DCCG_FIFO_ERRDET_OVR_EN = 1
Write 1 to OTGx_DROP_PIXEL for (N-4) times
Set DCCG_FIFO_ERRDET_OVR_EN = 0
Write DENTIST_DISPCLK_RDIVIDER = 126

Because of frequency stepping, sequence a can be executed to change the
divider from 127 to any other divider value.

b.	126 -> 127
Read  DIG_FIFO_CAL_AVERAGE_LEVEL
FIFO level N = DIG_FIFO_CAL_AVERAGE_LEVEL / 4
Set DCCG_FIFO_ERRDET_OVR_EN = 1
Write 1 to OTGx_ADD_PIXEL for (12-N) times
Set DCCG_FIFO_ERRDET_OVR_EN = 0
Write DENTIST_DISPCLK_RDIVIDER = 127

Because of frequency stepping, divider must first be set from any other
divider value to 126 before executing sequence b.

[PATCH AUTOSEL 5.13 114/189] drm/amdkfd: Fix circular lock in nocpsch path

[Sasha Levin]

From: Amber Lin <Amber.Lin@amd.com>

[ Upstream commit a7b2451d31cfa2e8aeccf3b35612ce33f02371fc ]

Calling free_mqd inside of destroy_queue_nocpsch_locked can cause a
circular lock. destroy_queue_nocpsch_locked is called under a DQM lock,
which is taken in MMU notifiers, potentially in FS reclaim context.
Taking another lock, which is BO reservation lock from free_mqd, while
causing an FS reclaim inside the DQM lock creates a problematic circular
lock dependency. Therefore move free_mqd out of
destroy_queue_nocpsch_locked and call it after unlocking DQM.
