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
f9b7f3703f ("drm/amdgpu/acpi: make ATPX/ATCS structures global (v2)").

Current RUNPM mechanism relies on PMFW to master the timing for BACO
in/exit. And that needs cooperation from sound driver for dstate
change notification for function 1(audio). Otherwise(on sound driver
missing), BACO cannot be kicked in correctly and hang will be observed
on RUNPM exit.
By switching back to legacy message way on sound driver missing,
we are able to fix the runpm hang observed for the scenario below:
amdgpu driver loaded -> runpm suspend kicked -> sound driver loaded

Add manual sclk/vddc setting supoort via pp_od_clk_voltage sysfs
to maintain consistency with other asics. As cyan skillfish doesn't
support DPM, there is only a single frequency and voltage to adjust.
v2: maintain consistency and add command guide.
v3: adjust user settings storage and coding style.
Command guide:
echo vc point sclk vddc > pp_od_clk_voltage
"vc" - sclk voltage curve
"point" - must be 0
"sclk" - target value of sclk(MHz), should be in safe range
"vddc" - target value of vddc(mV), a 6.25(mV) stepping is
recommended and should be in safe range (the real
vddc is an approximation of target value)
echo c > pp_od_clk_voltage
"c" - commit the changes of sclk and vddc, only after
the commit command, the target values set by "vc"
command will take effect
echo r > pp_od_clk_voltage
"r" - reset sclk and vddc to default value, a subsequent
commit command is needed to take effect
Example:
1) Check default sclk and vddc
$ cat pp_od_clk_voltage
OD_SCLK:
0: 1800Mhz *
OD_VDDC:
0: 862mV *
OD_RANGE:
SCLK: 1000Mhz 2000Mhz
VDDC: 700mV 1129mV
2) Set sclk to 1500MHz and vddc to 700mV
$ echo vc 0 1500 700 > pp_od_clk_voltage
$ echo c > pp_od_clk_voltage
$ cat pp_od_clk_voltage
OD_SCLK:
0: 1500Mhz *
OD_VDDC:
0: 693mV *
OD_RANGE:
SCLK: 1000Mhz 2000Mhz
VDDC: 700mV 1129mV
3) Reset sclk and vddc to default
$ echo r > pp_od_clk_voltage
$ echo c > pp_od_clk_voltage
$ cat pp_od_clk_voltage
OD_SCLK:
0: 1800Mhz *
OD_VDDC:
0: 874mV *
OD_RANGE:
SCLK: 1000Mhz 2000Mhz
VDDC: 700mV 1129mV
NOTE:
We don't specify an explicit safe range, you can set any values
between min and max at your own risk. Enjoy!

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.

In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally writing across neighboring fields.
The "Board Parameters" members of the structs:
struct atom_smc_dpm_info_v4_5
struct atom_smc_dpm_info_v4_6
struct atom_smc_dpm_info_v4_7
struct atom_smc_dpm_info_v4_10
are written to the corresponding members of the corresponding PPTable_t
variables, but they lack destination size bounds checking, which means
the compiler cannot verify at compile time that this is an intended and
safe memcpy().
Since the header files are effectively immutable[1] and a struct_group()
cannot be used, nor a common struct referenced by both sides of the
memcpy() arguments, add a new helper, amdgpu_memcpy_trailing(), to
perform the bounds checking at compile time. Replace the open-coded
memcpy()s with amdgpu_memcpy_trailing() which includes enough context
for the bounds checking.
"objdump -d" shows no object code changes.

This fixes a bug which if we probe a non-existing
I2C device, and the SMU returns 0xFF, from then on
we can never communicate with the SMU, because the
code before this patch reads and interprets 0xFF
as a terminal error, and thus we never write 0
into register 90 to clear the status (and
subsequently send a new command to the SMU.)
It is not an error that the SMU returns status
0xFF. This means that the SMU executed the last
command successfully (execution status), but the
command result is an error of some sort (execution
result), depending on what the command was.
When doing a status check of the SMU, before we
send a new command, the only status which
precludes us from sending a new command is 0--the
SMU hasn't finished executing a previous command,
and 0xFC--the SMU is busy.
This bug was seen as the following line in the
kernel log,
amdgpu: Msg issuing pre-check failed(0xff) and SMU may be not in the right state!
when subsequent SMU commands, not necessarily
related to I2C, were sent to the SMU.
This patch fixes this bug.
v2: Add a comment to the description of
__smu_cmn_poll_stat() to explain why we're NOT
defining the SMU FW return codes as macros, but
are instead hard-coding them. Such a change, can
be followed up by a subsequent patch.
v3: The changes are,
a) Add comments to break labels in
__smu_cmn_reg2errno().
b) When an unknown/unspecified/undefined result is
returned back from the SMU, map that to
-EREMOTEIO, to distinguish failure at the SMU
FW.
c) Add kernel-doc to
smu_cmn_send_msg_without_waiting(),
smu_cmn_wait_for_response(),
smu_cmn_send_smc_msg_with_param().
d) In smu_cmn_send_smc_msg_with_param(), since we
wait for completion of the command, if the
result of the completion is
undefined/unknown/unspecified, we print that to
the kernel log.
v4: a) Add macros as requested, though redundant, to
be removed when SMU consolidates for all
ASICs--see comment in code.
b) Get out if the SMU code is unknown.
v5: Rename the macro names.
