[PATCH AUTOSEL 6.11 130/244] drm/amd/display: Pass non-null to dcn20_validate_apply_pipe_split_flags

[PATCH AUTOSEL 6.11 130/244] drm/amd/display: Pass non-null to dcn20_validate_apply_pipe_split_flags

[Sasha Levin]

From: Alex Hung <alex.hung@amd.com>

[ Upstream commit 5559598742fb4538e4c51c48ef70563c49c2af23 ]

[WHAT & HOW]
"dcn20_validate_apply_pipe_split_flags" dereferences merge, and thus it
cannot be a null pointer. Let's pass a valid pointer to avoid null
dereference.

This fixes 2 FORWARD_NULL issues reported by Coverity.

[PATCH AUTOSEL 6.11 133/244] drm/amd/display: Check null pointers before multiple uses

[Sasha Levin]

From: Alex Hung <alex.hung@amd.com>

[ Upstream commit fdd5ecbbff751c3b9061d8ebb08e5c96119915b4 ]

[WHAT & HOW]
Poniters, such as stream_enc and dc->bw_vbios, are null checked previously
in the same function, so Coverity warns "implies that stream_enc and
dc->bw_vbios might be null". They are used multiple times in the
subsequent code and need to be checked.

This fixes 10 FORWARD_NULL issues reported by Coverity.

[PATCH AUTOSEL 6.11 134/244] drm/amdgpu: disallow multiple BO_HANDLES chunks in one submit

[Sasha Levin]

From: Pierre-Eric Pelloux-Prayer <pierre-eric.pelloux-prayer@amd.com>

[ Upstream commit fec5f8e8c6bcf83ed7a392801d7b44c5ecfc1e82 ]

Before this commit, only submits with both a BO_HANDLES chunk and a
'bo_list_handle' would be rejected (by amdgpu_cs_parser_bos).

But if UMD sent multiple BO_HANDLES, what would happen is:
* only the last one would be really used
* all the others would leak memory as amdgpu_cs_p1_bo_handles would
  overwrite the previous p->bo_list value

This commit rejects submissions with multiple BO_HANDLES chunks to
match the implementation of the parser.

[PATCH AUTOSEL 6.11 135/244] drm/amdkfd: amdkfd_free_gtt_mem clear the correct pointer

[Sasha Levin]

From: Philip Yang <Philip.Yang@amd.com>

[ Upstream commit c86ad39140bbcb9dc75a10046c2221f657e8083b ]

Pass pointer reference to amdgpu_bo_unref to clear the correct pointer,
otherwise amdgpu_bo_unref clear the local variable, the original pointer
not set to NULL, this could cause use-after-free bug.

[PATCH AUTOSEL 6.11 136/244] drm/amd/display: Add null check for head_pipe in dcn201_acquire_free_pipe_for_layer

[Sasha Levin]

From: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com>

[ Upstream commit f22f4754aaa47d8c59f166ba3042182859e5dff7 ]

This commit addresses a potential null pointer dereference issue in the
`dcn201_acquire_free_pipe_for_layer` function. The issue could occur
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.

[PATCH AUTOSEL 6.11 144/244] drm/amd/display: Use gpuvm_min_page_size_kbytes for DML2 surfaces

[Sasha Levin]

From: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>

[ Upstream commit 31663521ede2edb622ee1b397ae3ac666d6351c5 ]

[Why]
It's currently hard coded to 256 when it should be using the SOC
provided values. This can result in corruption with linear surfaces
where we prefetch more PTE than the buffer can hold.

[How]
Update the min page size correctly for the plane.

[PATCH AUTOSEL 6.11 150/244] drm/amd/display: Underflow Seen on DCN401 eGPU

[Sasha Levin]

From: Daniel Sa <Daniel.Sa@amd.com>

[ Upstream commit ca0fb243c3bb53dbbd71d16c76f319bf923ee3d4 ]

[WHY]
In dcn401 we read clock values before FW is loaded. These incorrect
values cause the driver to believe that we are running higher clocks
than what we actually have. This then causes corruption/underflow for
the eGPU.

[HOW]
When new values are read from HW, update internal structures to
propagate the new/correct value. Fixes issue

[PATCH AUTOSEL 6.11 151/244] drm/amd/display: Handle null 'stream_status' in 'planes_changed_for_existing_stream'

[Sasha Levin]

From: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com>

[ Upstream commit 8141f21b941710ecebe49220b69822cab3abd23d ]

This commit adds a null check for 'stream_status' in the function
'planes_changed_for_existing_stream'. Previously, the code assumed
'stream_status' could be null, but did not handle the case where it was
actually null. This could lead to a null pointer dereference.

Reported by smatch:
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_resource.c:3784 planes_changed_for_existing_stream() error: we previously assumed 'stream_status' could be null (see line 3774)

[PATCH AUTOSEL 6.11 152/244] drm/amd/display: Add NULL check for function pointer in dcn20_set_output_transfer_func

[Sasha Levin]

From: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com>

[ Upstream commit 62ed6f0f198da04e884062264df308277628004f ]

This commit adds a null check for the set_output_gamma function pointer
in the dcn20_set_output_transfer_func function. Previously,
set_output_gamma was being checked for null at line 1030, but then it
was being dereferenced without any null check at line 1048. This could
potentially lead to a null pointer dereference error if set_output_gamma
is null.

To fix this, we now ensure that set_output_gamma is not null before
dereferencing it. We do this by adding a null check for set_output_gamma
before the call to set_output_gamma at line 1048.

[PATCH AUTOSEL 6.11 156/244] drm/amd/display: Add null check for 'afb' in amdgpu_dm_update_cursor (v2)

[Sasha Levin]

From: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com>

[ Upstream commit 0fe20258b4989b9112b5e9470df33a0939403fd4 ]

This commit adds a null check for the 'afb' variable in the
amdgpu_dm_update_cursor function. Previously, 'afb' was assumed to be
null at line 8388, but was used later in the code without a null check.
This could potentially lead to a null pointer dereference.

Changes since v1:
- Moved the null check for 'afb' to the line where 'afb' is used. (Alex)

Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:8433 amdgpu_dm_update_cursor()
	error: we previously assumed 'afb' could be null (see line 8388)

[PATCH AUTOSEL 6.11 157/244] drm/amd/display: Check null pointers before using dc->clk_mgr

[Sasha Levin]

From: Alex Hung <alex.hung@amd.com>

[ Upstream commit 95d9e0803e51d5a24276b7643b244c7477daf463 ]

[WHY & HOW]
dc->clk_mgr is null checked previously in the same function, indicating
it might be null.

Passing "dc" to "dc->hwss.apply_idle_power_optimizations", which
dereferences null "dc->clk_mgr". (The function pointer resolves to
"dcn35_apply_idle_power_optimizations".)

This fixes 1 FORWARD_NULL issue reported by Coverity.

[PATCH AUTOSEL 6.11 161/244] drm/amd/display: fix double free issue during amdgpu module unload

[Sasha Levin]

From: Tim Huang <tim.huang@amd.com>

[ Upstream commit 20b5a8f9f4670a8503aa9fa95ca632e77c6bf55d ]

Flexible endpoints use DIGs from available inflexible endpoints,
so only the encoders of inflexible links need to be freed.
Otherwise, a double free issue may occur when unloading the
amdgpu module.

Enabling gfxoff quirk results in perfectly usable
graphical user interface on HP 705G4 DM with R5 2400G.

Without the quirk, X server is completely unusable as
every few seconds there is gpu reset due to ring gfx timeout.

From: Alex Hung <alex.hung@amd.com>

[ Upstream commit 6d64d39486197083497a01b39e23f2f8474b35d3 ]

[WHY]
dml2_core_shared_mode_support and dml_core_mode_support access the third
element of dummy_boolean, i.e. hw_debug5 = &s->dummy_boolean[2], when
dummy_boolean has size of 2. Any assignment to hw_debug5 causes an
OVERRUN.

[HOW]
Increase dummy_boolean's array size to 3.

This fixes 2 OVERRUN issues reported by Coverity.

[PATCH AUTOSEL 6.11 186/244] drm/amd/display: Fix index out of bounds in DCN30 degamma hardware format translation

[Sasha Levin]

From: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com>

[ Upstream commit bc50b614d59990747dd5aeced9ec22f9258991ff ]

This commit addresses a potential index out of bounds issue in the
`cm3_helper_translate_curve_to_degamma_hw_format` function in the DCN30
color  management module. The issue could occur when the index 'i'
exceeds the  number of transfer function points (TRANSFER_FUNC_POINTS).

The fix adds a check to ensure 'i' is within bounds before accessing the
transfer function points. If 'i' is out of bounds, the function returns
false to indicate an error.

[PATCH AUTOSEL 6.11 188/244] drm/amd/display: Implement bounds check for stream encoder creation in DCN401

[Sasha Levin]

From: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com>

[ Upstream commit bdf606810210e8e07a0cdf1af3c467291363b295 ]

'stream_enc_regs' array is an array of dcn10_stream_enc_registers
structures. The array is initialized with four elements, corresponding
to the four calls to stream_enc_regs() in the array initializer. This
means that valid indices for this array are 0, 1, 2, and 3.

The error message 'stream_enc_regs' 4 <= 5 below, is indicating that
there is an attempt to access this array with an index of 5, which is
out of bounds. This could lead to undefined behavior

Here, eng_id is used as an index to access the stream_enc_regs array. If
eng_id is 5, this would result in an out-of-bounds access on the
stream_enc_regs array.

Thus fixing Buffer overflow error in dcn401_stream_encoder_create

[PATCH AUTOSEL 6.11 192/244] drm/amd/display: Fix possible overflow in integer multiplication

[Sasha Levin]

From: Alex Hung <alex.hung@amd.com>

[ Upstream commit 3f96f545f877ac59d0c967f52d760b4b2b3b9a47 ]

[WHAT & HOW]
Integer multiplies integer may overflow in context that expects an
expression of unsigned long long (64 bits). This can be fixed by casting
integer to unsigned long long to force 64 bits results.

This fixes 2 OVERFLOW_BEFORE_WIDEN issues reported by Coverity.

[PATCH AUTOSEL 6.11 194/244] drm/amd/display: Avoid overflow assignment in link_dp_cts

[Sasha Levin]

From: Alex Hung <alex.hung@amd.com>

[ Upstream commit a15268787b79fd183dd526cc16bec9af4f4e49a1 ]

sampling_rate is an uint8_t but is assigned an unsigned int, and thus it
can overflow. As a result, sampling_rate is changed to uint32_t.

Similarly, LINK_QUAL_PATTERN_SET has a size of 2 bits, and it should
only be assigned to a value less or equal than 4.

This fixes 2 INTEGER_OVERFLOW issues reported by Coverity.

[PATCH AUTOSEL 6.11 202/244] drm/amd/display: Force enable 3DLUT DMA check for dcn401 in DML

[Sasha Levin]

From: Dillon Varone <dillon.varone@amd.com>

[ Upstream commit b8dc6ca028d9a39196a3a066b9ef2d4a5eca475d ]

[WHY]
Currently TR0 (trip 0) is not properly budgeting for urgent latency in
DML2.1. This results in overly aggressive prefetch schedules that are
vulnerable to request return jitter, resulting in severe underflow at
the start of the frame.

[HOW]
Forcing 3DLUT DMA check to enable causes urgent latency to be budgeted
properly into the prefetch schedule, avoiding the vulnerability.

Fix this by converting the if/else if/... construct into a proper
switch() statement with a default to handle the error case.

As a bonus, the generated code is ca. 100 bytes smaller (with gcc 11.4.0
targeting arm32).

[PATCH AUTOSEL 6.11 208/244] drm/amd/display: Unlock Pipes Based On DET Allocation

[Sasha Levin]

From: Austin Zheng <Austin.Zheng@amd.com>

[ Upstream commit 4af0d8ebf74ccbb60d33fdd410891283dd6cb109 ]

[Why]
DML21 does not allocate DET evenly between pipes.
May result in underflow when unlocking the pipes as DET could
be overallocated.

[How]
1. Unlock pipes that have a decreased amount of DET allocation
2. Wait for the double buffer to be updated.
3. Unlock the remaining pipes.

[PATCH AUTOSEL 6.11 217/244] drm/amdkfd: Check int source id for utcl2 poison event

[Sasha Levin]

From: Hawking Zhang <Hawking.Zhang@amd.com>

[ Upstream commit db6341a9168d2a24ded526277eeab29724d76e9d ]

Traditional utcl2 fault_status polling does not
work in SRIOV environment. The polling of fault
status register from guest side will be dropped
by hardware.

Driver should switch to check utcl2 interrupt
source id to identify utcl2 poison event. It is
set to 1 when poisoned data interrupts are
signaled.

v2: drop the unused local variable (Tao)
