[ Upstream commit 6917112af2ba36c5f19075eb9f2933ffd07e55bf ]
Remove extra multiplication.
CIK GPUs such as Hawaii appear to use PP_TABLE_V0 in which case
the shutdown temperature is hardcoded in smu7_init_dpm_defaults
and is already multiplied by 1000. The value was mistakenly
multiplied another time by smu7_get_thermal_temperature_range.

[ Upstream commit 357d90be2c7aaa526a840cddffd2b8d676fe75a6 ]
Chips which use the IP discovery firmware loaded by the driver
reported incorrect harvesting information in the ip discovery
table in sysfs because the driver only uses the ip discovery
firmware for populating sysfs and not for direct parsing for the
driver itself as such, the fields that are used to print the
harvesting info in sysfs report incorrect data for some IPs. Populate
the relevant fields for this case as well.

[ Upstream commit 0a6e9e098fcc318fec0f45a05a5c4743a81a60d9 ]
[Why]
commit 530694f54dd5e ("drm/amdgpu: do not resume device in thaw for
normal hibernation") optimized the flow for systems that are going
into S4 where the power would be turned off. Basically the thaw()
callback wouldn't resume the device if the hibernation image was
successfully created since the system would be powered off.
This however isn't the correct flow for a system entering into
s0i3 after the hibernation image is created. Some of the amdgpu
callbacks have different behavior depending upon the intended
state of the suspend.
[How]
Use pm_hibernation_mode_is_suspend() as an input to decide whether
to run resume during thaw() callback.

[Why]
Not all renoir hardware supports secure display. If the TA is present
but the feature isn't supported it will fail to load or send commands.
This shows ERR messages to the user that make it seems like there is
a problem.

commit 6df8e84aa6b5b1812cc2cacd6b3f5ccbb18cda2b upstream.
The atomic variable vm_fault_info_updated is used to synchronize access to
adev->gmc.vm_fault_info between the interrupt handler and
get_vm_fault_info().
The default atomic functions like atomic_set() and atomic_read() do not
provide memory barriers. This allows for CPU instruction reordering,
meaning the memory accesses to vm_fault_info and the vm_fault_info_updated
flag are not guaranteed to occur in the intended order. This creates a
race condition that can lead to inconsistent or stale data being used.
The previous implementation, which used an explicit mb(), was incomplete
and inefficient. It failed to account for all potential CPU reorderings,
such as the access of vm_fault_info being reordered before the atomic_read
of the flag. This approach is also more verbose and less performant than
using the proper atomic functions with acquire/release semantics.
Fix this by switching to atomic_set_release() and atomic_read_acquire().
These functions provide the necessary acquire and release semantics,
which act as memory barriers to ensure the correct order of operations.
It is also more efficient and idiomatic than using explicit full memory
barriers.

commit ddbfac152830e38d488ff8e45ab7eaf5d72f8527 upstream.
The point of isolating code that uses kernel mode FPU in separate
compilation units is to ensure that even implicit uses of, e.g., SIMD
registers for spilling occur only in a context where this is permitted,
i.e., from inside a kernel_fpu_begin/end block.
This is important on arm64, which uses -mgeneral-regs-only to build all
kernel code, with the exception of such compilation units where FP or
SIMD registers are expected to be used. Given that the compiler may
invent uses of FP/SIMD anywhere in such a unit, none of its code may be
accessible from outside a kernel_fpu_begin/end block.
This means that all callers into such compilation units must use the
DC_FP start/end macros, which must not occur there themselves. For
robustness, all functions with external linkage that reside there should
call dc_assert_fp_enabled() to assert that the FPU context was set up
correctly.
Fix this for the DCN35, DCN351 and DCN36 implementations.

Port of commit 227545b9a08c ("drm/radeon/dpm: Disable sclk

This is an ad-hoc DPM fix, necessary because we don't have

We define "high pixelclock" for SI as higher than necessary
for 4K 30Hz. For example, 4K 60Hz and 1080p 144Hz fall into
this category.

[ Upstream commit ce025130127437dc884c84c254170e27b2ce9309 ]
Based on some comments in dm_pp_display_configuration
above the crtc_index and line_time fields, these values
are programmed to the SMC to work around an SMC hang
when it switches MCLK.
According to Alex, the Windows driver programs them to:
mclk_change_block_cp_min = 200 / line_time
mclk_change_block_cp_max = 100 / line_time
Let's use the same for the sake of consistency.
Previously we used the watermark values, but it seemed buggy
as the code was mixing up low/high and A/B watermarks, and
was not saving a low watermark value on DCE 6, so
mclk_change_block_cp_max would be always zero previously.
Split this change off from the previous si_upload_smc_data
to make it easier to bisect, in case it causes any issues.

[ Upstream commit a43b2cec04b02743338aa78f837ee0bdf066a6d5 ]
The si_upload_smc_data function uses si_write_smc_soft_register
to set some register values in the SMC, and expects the result

The PPSMC_Result_OK / PPSMC_Result_Failed values are used for
checking the result of a command sent to the SMC.
However, the si_write_smc_soft_register actually doesn't send
any commands to the SMC and returns zero on success,
so this check was incorrect.
Fix that by not checking the return value, just like other
calls to si_write_smc_soft_register.

[ Upstream commit bf4e4b97d0fdc66f04fc19d807e24dd8421b8f11 ]
The function dc_stream_set_cursor_attributes() currently dereferences
the `stream` pointer and nested members `stream->ctx->dc->current_state`
without checking for NULL.
All callers of these functions, such as in
`dcn30_apply_idle_power_optimizations()` and
`amdgpu_dm_plane_handle_cursor_update()`, already perform NULL checks
before calling these functions.
Fixes below:
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_stream.c:336 dc_stream_program_cursor_attributes()
error: we previously assumed 'stream' could be null (see line 334)
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_stream.c
327 bool dc_stream_program_cursor_attributes(
328 struct dc_stream_state *stream,
329 const struct dc_cursor_attributes *attributes)
330 {
331 struct dc *dc;
332 bool reset_idle_optimizations = false;
333
334 dc = stream ? stream->ctx->dc : NULL;
^^^^^^
The old code assumed stream could be NULL.
335
--> 336 if (dc_stream_set_cursor_attributes(stream, attributes)) {
^^^^^^
The refactor added an unchecked dereference.
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_stream.c
313 bool dc_stream_set_cursor_attributes(
314 struct dc_stream_state *stream,
315 const struct dc_cursor_attributes *attributes)
316 {
317 bool result = false;
318
319 if (dc_stream_check_cursor_attributes(stream, stream->ctx->dc->current_state, attributes)) {
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Here.
This function used to check for if stream as NULL and return false at
the start. Probably we should add that back.

[Why]
We did not initialize dc clocks with boot-time hw values during init.
This lead to incorrect clock values in dc, causing `dcn35_update_clocks`
to make incorrect updates.

s/dump/save/ as that accurately reflects the purpose of the functions.

On clients that utilize AMD_PRIVATE_COLOR properties for HDR support,
brightness sliders can include a hardware controlled portion and a
gamma-based portion. This is the case on the Steam Deck OLED when using
gamescope with Steam as a client.
When a user sets a brightness level while HDR is active, the gamma-based
portion and/or hardware portion are adjusted to achieve the desired
brightness. However, when a modeset takes place while the gamma-based
portion is in-use, restoring the hardware brightness level overrides the
user's overall brightness level and results in a mismatch between what
the slider reports and the display's current brightness.
To avoid overriding gamma-based brightness, only restore HW backlight
level after boot or resume. This ensures that the backlight level is
set correctly after the DC layer resets it while avoiding interference
with subsequent modesets.

SMU hang can occur if the interrupts are not enabled appropriately,
causing a vblank timeout.
This patch reverts commit 5009628d8509 ("drm/amd/display: Remove unnecessary
amdgpu_irq_get/put"), but only for RX6xxx & RX7700 GPUs, on which the
issue was observed.
This will re-enable interrupts regardless of whether the user space needed
it or not.

Enable the cleaner shader for additional GFX11.0.1/11.0.4 series GPUs to
ensure data isolation among GPU tasks. The cleaner shader is tasked with
clearing the Local Data Store (LDS), Vector General Purpose Registers
(VGPRs), and Scalar General Purpose Registers (SGPRs), which helps avoid
data leakage and guarantees the accuracy of computational results.
This update extends cleaner shader support to GFX11.0.1/11.0.4 GPUs,
previously available for GFX11.0.3. It enhances security by clearing GPU
memory between processes and maintains a consistent GPU state across KGD
and KFD workloads.
