This reverts commit 6b2fb172853261829229237766d078638267042f which is
commit fa57924c76d995e87ca3533ec60d1d5e55769a27 upstream.
It breaks the build on arm64 and arm systems, and trying to unwind the
ifdef mess to fix it up was not simple at all. So revert it and wait
for a fixed change to come back.

dc_stream_program_cursor_position
commit fa4c500ce93f4f933c38e6d6388970e121e27b21 upstream.
The fix involves adding a null check for 'stream' at the beginning of
the function. If 'stream' is NULL, the function immediately returns
false. This ensures that 'stream' is not NULL when we dereference it to
access 'ctx' in 'dc = stream->ctx->dc;' the function.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_stream.c:398 dc_stream_program_cursor_position()
error: we previously assumed 'stream' could be null (see line 397)
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_stream.c
389 bool dc_stream_program_cursor_position(
390 struct dc_stream_state *stream,
391 const struct dc_cursor_position *position)
392 {
393 struct dc *dc;
394 bool reset_idle_optimizations = false;
395 const struct dc_cursor_position *old_position;
396
397 old_position = stream ? &stream->cursor_position : NULL;
^^^^^^^^
The patch adds a NULL check
--> 398 dc = stream->ctx->dc;
^^^^^^^^
The old code didn't check
399
400 if (dc_stream_set_cursor_position(stream, position)) {
401 dc_z10_restore(dc);
402
403 /* disable idle optimizations if enabling cursor */
404 if (dc->idle_optimizations_allowed &&
405 (!old_position->enable || dc->debug.exit_idle_opt_for_cursor_updates) &&
406 position->enable) {
407 dc_allow_idle_optimizations(dc, false);

commit e33697141bac18906345ea46533a240f1ad3cd21 upstream.
[Why]
In dm resume, we firstly restore dc state and do the mst resume for topology
probing thereafter. If we change dpcd DP_MSTM_CTRL value after LT in mst reume,
it will cause light up problem on the hub.
[How]
Revert commit 202dc359adda ("drm/amd/display: Defer handling mst up request in resume").
And adjust the reason to trigger dc_link_detect by DETECT_REASON_RESUMEFROMS3S4.

commit f63f86b5affcc2abd1162f11824b9386fc06ac94 upstream.
We're seeing issues when user-space tries to do an atomic update of
the primary surface, as well as the cursor. These two updates are
separate calls into DC and don't currently act as an atomic update.
This might lead to cursor updates being locked out and cursors
stuttering.
In order to solve this problem we want to separate the setting
and programming of cursor attributes and position. That's what
we're doing in this patch. The subsequent patch will then be
able to use the cursor setters in independent cursor updates,
as well as in atomic commits.

commit 202dc359addab29451d3d18243c3d957da5392c8 upstream.
[Why]
Like commit ec5fa9fcdeca ("drm/amd/display: Adjust the MST resume flow"), we
want to avoid handling mst topology changes before restoring the old state.
If we enable DP_UP_REQ_EN before calling drm_atomic_helper_resume(), have
changce to handle CSN event first and fire hotplug event before restoring the
cached state.
[How]
Disable mst branch sending up request event before we restoring the cached state.
DP_UP_REQ_EN will be set later when we call drm_dp_mst_topology_mgr_resume().

commit 2d696cc837eaf5394d79bfd2b0b0483c4778aa83 upstream.
[Why]
Currently disabling ASSR before stream is disabled causes visible
display corruption.
[How]
Move disable ASSR command to after stream has been disabled.

commit 899d92fd26fe780aad711322aa671f68058207a6 upstream.
[WHY]
When switching from "Extend" to "Second Display Only" we sometimes
call resource_get_otg_master_for_stream on a stream for the eDP,
which is disconnected. This leads to a null pointer dereference.
[HOW]
Added a null check in dc_resource.c/resource_log_pipe_topology_update.

[ Upstream commit f2aaed194a54d78c307c44d1829c7e1ba67e9ba5 ]
In the commit c2cec7a872b6 ("drm/amd/display: Wake DMCUB before sending
a command for replay feature"), replaced dm_execute_dmub_cmd with
dc_wake_and_execute_dmub_cmd in multiple areas, but due to merge issues
the replacement of this function in the dmub_replay_copy_settings was
missed. This commit replaces the old dm_execute_dmub_cmd with
dc_wake_and_execute_dmub_cmd.

This error happens when the color log tries to read the gamut remap
information from DCN401 which is not initialized in the dcn401_dpp_funcs
which leads to a null pointer dereference. This commit addresses this
issue by adding a proper guard to access the gamut_remap callback in
case the specific ASIC did not implement this function.

[ Upstream commit 3ddd9c83ff7ac0ead38188425b14d03dc2f2c133 ]
[why]
There are cases where update pipe params could fail but dpp pipes are already
added to the state. In this case, we should remove dpp pipes so dc state is
restored back. If it is not restored, dc state is corrupted after calling this
function, so if we call the same interface with the corrupted state again, we
may end up programming pipe topology based on a corrupted dc state.

[ Upstream commit fcf6a49d79923a234844b8efe830a61f3f0584e4 ]
[Why]
When unplug one of monitors connected after mst hub, encounter null pointer dereference.
It's due to dc_sink get released immediately in early_unregister() or detect_ctx(). When
commit new state which directly referring to info stored in dc_sink will cause null pointer
dereference.
[how]
Remove redundant checking condition. Relevant condition should already be covered by checking
if dsc_aux is null or not. Also reset dsc_aux to NULL when the connector is disconnected.

[ Upstream commit 9a29c4adb0997be6ba3dd92dfba14ea75a8c6ce4 ]
[why]
We need to decrease ODM slice when adding or removing planes because MPO
support takes precedence over dynamic ODM combine. However there is a case where
we remove ODM combine even for ODM combine required timing in the initial new
dc state. This is normally okay because ODM will be added back after we pass DML
bandwidth validation. However since we remove ODM combine in the initial new
state, the previous ODM pipe allocation is lost. This may cause the new plane to
take away the original secondary OPP head pipe that is still required in the new
state.
For a timing that requires ODM 2:1 but optimized with ODM 4:1, if we add an MPO
plane, we will not have enough pipe to preserve ODM 4:1. In this case we should
reduce ODM slice count then try to add the MPO plane again. By reducing, we are
gradually remove 1 ODM slice from right most side one at a time until we have
enough free pipes for the new plane. If we remove ODM combine entirely, we could
use the pipe at ODM slice index 1 as a DPP pipe for the new plane. But ODM slice
1 is still needed as the timing requires ODM 2:1. This transition is not
seamless and user will see corruption on the screen.
[how]
Remove single ODM slice one at time until we have enough pipes for a new plane.
Remove previous logic to always remove ODM combine entirely.

[ Upstream commit 3601a35a2e9d640233f4bc3496f7603b93f9c143 ]
[Why]
We can hang in place trying to send commands when the DMCUB isn't
powered on.
[How]
For functions that execute within a DC context or DC lock we can wrap
the direct calls to dm_execute_dmub_cmd/list with code that exits idle
power optimizations and reallows once we're done with the command
submission on success.
For DM direct submissions the DM will need to manage the enter/exit
sequencing manually.
We cannot invoke a DMCUB command directly within the DM execution helper
or we can deadlock.

amdgpu_dm_plane_handle_cursor_update
[ Upstream commit 38e6f715b02b572f74677eb2f29d3b4bc6f1ddff ]
This commit adds a null check for the 'afb' variable in the
amdgpu_dm_plane_handle_cursor_update function. Previously, 'afb' was
assumed to be null, but was used later in the code without a null check.
This could potentially lead to a null pointer dereference.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_plane.c:1298 amdgpu_dm_plane_handle_cursor_update() error: we previously assumed 'afb' could be null (see line 1252)

[ Upstream commit 15c2990e0f0108b9c3752d7072a97d45d4283aea ]
This commit adds null checks for the 'stream' and 'plane' variables in
the dcn30_apply_idle_power_optimizations function. These variables were
previously assumed to be null at line 922, but they were used later in
the code without checking if they were null. This could potentially lead
to a null pointer dereference, which would cause a crash.
The null checks ensure that 'stream' and 'plane' are not null before
they are used, preventing potential crashes.
Fixes the below static smatch checker:
drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn30/dcn30_hwseq.c:938 dcn30_apply_idle_power_optimizations() error: we previously assumed 'stream' could be null (see line 922)

commit 5659b0c93a1ea02c662a030b322093203f299185 upstream.
[Why]
Page table of compute VM in the VRAM will lost after gpu reset.
VRAM won't be restored since compute VM has no shadows.
[How]
Use higher 32-bit of vm->generation to record a vram_lost_counter.
Reset the VM state machine when vm->genertaion is not equal to
the new generation token.
v2: Check vm->generation instead of calling drm_sched_entity_error
in amdgpu_vm_validate.
v3: Use new generation token instead of vram_lost_counter for check.

commit a03ebf116303e5d13ba9a2b65726b106cb1e96f6 upstream.
We seem to have a case where SDMA will sometimes miss a doorbell
if GFX is entering the powergating state when the doorbell comes in.
To workaround this, we can update the wptr via MMIO, however,
this is only safe because we disallow gfxoff in begin_ring() for
SDMA 5.2 and then allow it again in end_ring().
Enable this workaround while we are root causing the issue with
the HW team.

[ Upstream commit 745f7170db4ffd2f2e9751a2c719a97c9a5fc438 ]
This commit fixes a type mismatch in the amdgpu_gfx_kiq_init_ring
function triggered by the snprintf function expecting unsigned char
arguments due to the '%hhu' format specifier, but receiving int and u32
arguments.
The issue occurred because the arguments xcc_id, ring->me, ring->pipe,
and ring->queue were of type int and u32, not unsigned char. This led to
a type mismatch when these arguments were passed to snprintf.
To resolve this, the snprintf line was modified to cast these arguments
to unsigned char. This ensures that the arguments are of the correct
type for the '%hhu' format specifier and resolves the warning.
Fixes the below:
>> drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c:333:4: warning: format
>> specifies type 'unsigned char' but the argument has type 'int'
>> [-Wformat]

[ Upstream commit 6d438caaeaa1a7fae7b523e7bc4cee262b9f101a ]
The graphics_object_id structure is meant to fit into 32 bits, as it's
passed by value in and out of functions. A recent change increased
the size to 128 bits, so it's now always passed by reference, which
is clearly not intended and ends up producing a compile-time warning:

the 'enum' type change.

[ Upstream commit 0ea55445554209913a72eab86b60f5788776c4d6 ]
This commit fixes a format truncation issue arosed by the snprintf
function potentially writing more characters into the ring->name buffer
than it can hold, in the amdgpu_gfx_kiq_init_ring function
The issue occurred because the '%d' format specifier could write between
1 and 10 bytes into a region of size between 0 and 8, depending on the
values of xcc_id, ring->me, ring->pipe, and ring->queue. The snprintf
function could output between 12 and 41 bytes into a destination of size
16, leading to potential truncation.
To resolve this, the snprintf line was modified to use the '%hhu' format
specifier for xcc_id, ring->me, ring->pipe, and ring->queue. The '%hhu'
specifier is used for unsigned char variables and ensures that these
values are printed as unsigned decimal integers.
Fixes the below with gcc W=1:
drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c: In function ‘amdgpu_gfx_kiq_init_ring’:
drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c:332:61: warning: ‘%d’ directive output may be truncated writing between 1 and 10 bytes into a region of size between 0 and 8 [-Wformat-truncation=]
