a8f77e1658 drm/amd/display: Assign normalized_pix_clk when color depth = 14
commit 79e31396fd upstream.

[WHY & HOW]
A warning message "WARNING: CPU: 4 PID: 459 at ... /dc_resource.c:3397
calculate_phy_pix_clks+0xef/0x100 [amdgpu]" occurs because the
display_color_depth == COLOR_DEPTH_141414 is not handled. This is
observed in Radeon RX 6600 XT.

It is fixed by assigning pix_clk * (14 * 3) / 24 - same as the rests.

Also fixes the indentation in get_norm_pix_clk.

8e91a61678 drm/amd/display: Restore correct backlight brightness after a GPU reset
commit 5760388d96 upstream.

[Why]
GPU reset will attempt to restore cached state, but brightness doesn't
get restored. It will come back at 100% brightness, but userspace thinks
it's the previous value.

[How]
When running resume sequence if GPU is in reset restore brightness
to previous value.

8082ca0dd2 drm/amd/display: Disable unneeded hpd interrupts during dm_init
commit 40b8c14936 upstream.

[Why]

It seems HPD interrupts are enabled by default for all connectors, even
if the hpd source isn't valid. An eDP for example, does not have a valid
hpd source (but does have a valid hpdrx source; see construct_phy()).
Thus, eDPs should have their hpd interrupt disabled.

In the past, this wasn't really an issue. Although the driver gets
interrupted, then acks by writing to hw registers, there weren't any
subscribed handlers that did anything meaningful (see
register_hpd_handlers()).

But things changed with the introduction of IPS. s2idle requires that
the driver allows IPS for DMUB fw to put hw to sleep. Since register
access requires hw to be awake, the driver will block IPS entry to do
so. And no IPS means no hw sleep during s2idle.

This was the observation on DCN35 systems with an eDP. During suspend,
the eDP toggled its hpd pin as part of the panel power down sequence.
The driver was then interrupted, and acked by writing to registers,
blocking IPS entry.

[How]

Since DC marks eDP connections as having invalid hpd sources (see
construct_phy()), DM should disable them at the hw level. Do so in
amdgpu_dm_hpd_init() by disabling all hpd ints first, then selectively
enabling ones for connectors that have valid hpd sources.

commit 374c9faac5 upstream.

Null pointer dereference issue could occur when pipe_ctx->plane_state
is null. The fix adds a check to ensure 'pipe_ctx->plane_state' is not
null before accessing. This prevents a null pointer dereference.

2a3f4e270d drm/amdgpu: disable BAR resize on Dell G5 SE
[ Upstream commit 099bffc7ca ]

There was a quirk added to add a workaround for a Sapphire
RX 5600 XT Pulse that didn't allow BAR resizing.  However,
the quirk caused a regression with runtime pm on Dell laptops
using those chips, rather than narrowing the scope of the
resizing quirk, add a quirk to prevent amdgpu from resizing
the BAR on those Dell platforms unless runtime pm is disabled.

v2: update commit message, add runpm check

c18438959b drm/amdgpu: Check extended configuration space register when system uses large bar
[ Upstream commit e372baeb3d ]

Some customer platforms do not enable mmconfig for various reasons,
such as bios bug, and therefore cannot access the GPU extend configuration
space through mmio.

When the system enters the d3cold state and resumes, the amdgpu driver
fails to resume because the extend configuration space registers of
GPU can't be restored. At this point, Usually we only see some failure
dmesg log printed by amdgpu driver, it is difficult to find the root
cause.

Therefor print a warnning message if the system can't access the
extended configuration space register when using large bar.

This commit addresses a potential null pointer dereference issue in the

when `head_pipe` is null.

The fix adds a check to ensure `head_pipe` is not null before asserting
it. If `head_pipe` is null, the function returns NULL to prevent a
potential null pointer dereference.

0b7b07cb59 Revert "drm/amdgpu: rework resume handling for display (v2)"
This reverts commit 2daba7d857 which is
commit 73dae652dc upstream.

The original patch 73dae652dc (drm/amdgpu: rework resume handling for
display (v2)), was only targeted at kernels 6.11 and newer.  It did not
apply cleanly to 6.12 so I backported it and it backport landed as
99a02eab82 ("drm/amdgpu: rework resume handling for display (v2)"),
however there was a bug in the backport that was subsequently fixed in
063d380ca2 ("drm/amdgpu: fix backport of commit 73dae652dcac").  None
of this was intended for kernels older than 6.11, however the original
backport eventually landed in 6.6, 6.1, and 5.15.

Please revert the change from kernels 6.6, 6.1, and 5.15.

08ac5fdb9c drm/amd/display: Fix out-of-bounds access in 'dcn21_link_encoder_create'
commit 63de35a8fc upstream.

An issue was identified in the dcn21_link_encoder_create function where
an out-of-bounds access could occur when the hpd_source index was used
to reference the link_enc_hpd_regs array. This array has a fixed size
and the index was not being checked against the array's bounds before
accessing it.

This fix adds a conditional check to ensure that the hpd_source index is
within the valid range of the link_enc_hpd_regs array. If the index is
out of bounds, the function now returns NULL to prevent undefined
behavior.

d0fafe701c drm/amdkfd: Correct the migration DMA map direction
[ Upstream commit 5c3de6b02d ]

The SVM DMA device map direction should be set the same as
the DMA unmap setting, otherwise the DMA core will report
the following warning.

Before finialize this solution, there're some discussion on
the DMA mapping type(stream-based or coherent) in this KFD
migration case, followed by https://lore.kernel.org/all/04d4ab32
-45a1-4b88-86ee-fb0f35a0ca40@amd.com/T/.

As there's no dma_sync_single_for_*() in the DMA buffer accessed
that because this migration operation should be sync properly and
automatically. Give that there's might not be a performance problem
in various cache sync policy of DMA sync. Therefore, in order to
simplify the DMA direction setting alignment, let's set the DMA map
direction as BIDIRECTIONAL.

e8b8c1ecbd drm/amd/display: Fix incorrect DSC recompute trigger
[ Upstream commit 4641169a8c ]

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.

3f9f631f9b drm/amd/display: Fix DSC-re-computing
[ Upstream commit b9b5a82c53 ]

[Why]
This fixes a bug introduced by commit c536555451 ("drm/amd/display: dsc
mst re-compute pbn for changes on hub").
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.

60b57dc761 drm/amdkfd: pause autosuspend when creating pdd
[ Upstream commit 438b39ac74 ]

When using MES creating a pdd will require talking to the GPU to
setup the relevant context. The code here forgot to wake up the GPU
in case it was in suspend, this causes KVM to EFAULT for passthrough
GPU for example. This issue can be masked if the GPU was woken up by
other things (e.g. opening the KMS node) first and have not yet gone to sleep.

9f7042ffc7 drm/amdkfd: drop struct kfd_cu_info
[ Upstream commit 0021d70a06 ]

I think this was an abstraction back from when
kfd supported both radeon and amdgpu.  Since we just
support amdgpu now, there is no more need for this and
we can use the amdgpu structures directly.

This also avoids having the kfd_cu_info structures on
the stack when inlining which can blow up the stack.

da6b2c626a drm/amdgpu: don't access invalid sched
[ Upstream commit a93b1020eb ]

Since 2320c9e6a7 ("drm/sched: memset() 'job' in drm_sched_job_init()")
accessing job->base.sched can produce unexpected results as the initialisation
of (*job)->base.sched done in amdgpu_job_alloc is overwritten by the
memset.

This commit fixes an issue when a CS would fail validation and would
be rejected after job->num_ibs is incremented. In this case,
amdgpu_ib_free(ring->adev, ...) will be called, which would crash the
machine because the ring value is bogus.

To fix this, pass a NULL pointer to amdgpu_ib_free(): we can do this
because the device is actually not used in this function.

The next commit will remove the ring argument completely.

4e3f73221d drm/amdgpu: skip amdgpu_device_cache_pci_state under sriov
[ Upstream commit afe260df55 ]

Under sriov, host driver will save and restore vf pci cfg space during
reset. And during device init, under sriov, pci_restore_state happens after
