[ Upstream commit 68e3871dcd6e547f6c47454492bc452356cb9eac ]

When selecting between levels in the force performance levels interface
sclk (gfxclk) was not set correctly for all levels.  Select the proper
sclk settings for all levels.

commit ab39d3cef526ba09c4c6923b4cd7e6ec1c5d4faa upstream.

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)").

[ Upstream commit b3dc549986eb7b38eba4a144e979dc93f386751f ]

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.

commit 8b514e898ee7f861eb8863c647d258f71053af40 upstream.

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

Fix a bug in smu_cmn_send_msg_without_waiting() in
that this function does not need to take the
smu->message_lock mutex in order to send a message
down to the SMU. The mutex is acquired by the
caller of this function instead.

[ Upstream commit 5810323ba692895b045e3f1b3e107605c3717dab ]

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.
