The two AMD drivers have their own custom offsetof() implementation
that now triggers a warning with recent versions of clang:
drivers/gpu/drm/radeon/radeon_atombios.c:133:14: error: performing pointer subtraction with a null pointer has undefined behavior [-Werror,-Wnull-pointer-subtraction]
Change all the instances to use the normal offsetof() provided
by the kernel that does not have this problem.

Update the current state as boot state during dpm initialization.
During the subsequent initialization, set_power_state gets called to
transition to the final power state. set_power_state refers to values
from the current state and without current state populated, it could
result in NULL pointer dereference.
For ex: on platforms where PCI speed change is supported through ACPI
ATCS method, the link speed of current state needs to be queried before
deciding on changing to final power state's link speed. The logic to query
ATCS-support was broken on certain platforms. The issue became visible
when broken ATCS-support logic got fixed with commit
f9b7f3703ff9 ("drm/amdgpu/acpi: make ATPX/ATCS structures global (v2)").

Due to high latency in PCIE clock switching on RKL platforms,
switching the PCIE clock dynamically at runtime can lead to HDMI/DP
audio problems. On newer asics this is handled in the SMU firmware.
For SMU7-based asics, disable PCIE clock switching to avoid the issue.
AMD provide a parameter to disable PICE_DPM.
modprobe amdgpu ppfeaturemask=0xfff7bffb
It's better to contorl PCIE_DPM in amd gpu driver,
switch PCI_DPM by determining intel RKL platform for SMU7-based asics.

Create new structure SISLANDS_SMC_SWSTATE_SINGLE, as initialState.levels
and ACPIState.levels are never actually used as flexible arrays. Those
arrays can be used as simple objects of type
SISLANDS_SMC_HW_PERFORMANCE_LEVEL, instead.
Currently, the code fails because flexible array _levels_ in
struct SISLANDS_SMC_SWSTATE doesn't allow for code that accesses
the first element of initialState.levels and ACPIState.levels
arrays:
drivers/gpu/drm/amd/pm/powerplay/si_dpm.c:
4820: table->initialState.levels[0].mclk.vDLL_CNTL =
4821: cpu_to_be32(si_pi->clock_registers.dll_cntl);
...
5021: table->ACPIState.levels[0].mclk.vDLL_CNTL =
5022: cpu_to_be32(dll_cntl);
because such element cannot be accessed without previously allocating
enough dynamic memory for it to exist (which never actually happens).
So, there is an out-of-bounds bug in this case.
That's why struct SISLANDS_SMC_SWSTATE should only be used as type
for object driverState and new struct SISLANDS_SMC_SWSTATE_SINGLE is
created as type for objects initialState, ACPIState and ULVState.
Also, with the change from one-element array to flexible-array member
in commit 0e1aa13ca3ff ("drm/amd/pm: Replace one-element array with
flexible-array in struct SISLANDS_SMC_SWSTATE"), the size of
dpmLevels in struct SISLANDS_SMC_STATETABLE should be fixed to be
SISLANDS_MAX_SMC_PERFORMANCE_LEVELS_PER_SWSTATE instead of
SISLANDS_MAX_SMC_PERFORMANCE_LEVELS_PER_SWSTATE - 1.

Remove redundant ras->supported, as this value
is also stored in adev->ras_features.
Use adev->ras_features, as that supercedes "ras",
since the latter is its member.
The dependency goes like this:
ras <== adev->ras_features <== hw_supported,
and is read as "ras depends on ras_features, which
depends on hw_supported." The arrows show the flow
of information, i.e. the dependency update.
"hw_supported" should also live in "adev".

_ATOM_Vega10_GFXCLK_Dependency_Table
There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].
Use flexible-array member in struct _ATOM_Vega10_GFXCLK_Dependency_Table,
instead of one-element array.
Also, this helps with the ongoing efforts to enable -Warray-bounds and
fix the following warning:
drivers/gpu/drm/amd/amdgpu/../pm/powerplay/hwmgr/vega10_hwmgr.c: In function ‘vega10_get_pp_table_entry_callback_func’:

SISLANDS_SMC_SWSTATE
There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].
Refactor the code according to the use of a flexible-array member in
struct SISLANDS_SMC_SWSTATE, instead of a one-element array, and use
the struct_size() helper to calculate the size for the allocation.
Also, this helps with the ongoing efforts to enable -Warray-bounds and
fix the following warnings:
drivers/gpu/drm/amd/amdgpu/../pm/powerplay/si_dpm.c:2448:20: warning: array

"power_dpm_force_perfomance_level"
There are spelling mistakes in error and warning messages, the text
power_dpm_force_perfomance_level is missing a letter r and should be
power_dpm_force_performance_level. Fix them.

This patch is to make the error log more clear for fine grain tuning
function, it covers Raven/Raven2/Picasso/Renoir/Vangogh.
The fine grain tuning function uses the sysfs file -- pp_od_clk_voltage,
but only when another sysfs file -- power_dpm_force_performance_level is
switched to "manual" mode, it is allowed to access "pp_od_clk_voltage".
