0d6516efff drm/amd/pm:add new gpu_metrics_v2_3 to acquire average temperature info
Add new gpu_metrics_v2_3 to acquire average temperature info from SMU metrics. To acquire average temp info from gpu_metrics interface, but gpu_metrics_v2_2 only has members to show current temp info.
---
v1:
	Only add average_temperature_gfx in gpu_metrics_v2_3.
v2:
	Add average temp members for soc, core and l3 in gpu_metrics_v2_3 and put these new members at the end of gpu_metrics_v2_3. Add operation to read average temp info from metrics table.
v3:
	Merge v1 and v2 and rename the patch.
v4:
	Merge v3. Add firmware version judgment in vangogh_common_get_gpu_metrics to maintain backward compatibility and rename the patch. "return ret" on error scenario in smu_cmn_get_smc_version.

f24044bd9b amdgpu/pm: Clarify documentation of error handling in send_smc_mesg
Clarify the smu_cmn_send_smc_msg_with_param documentation to mention two
cases exist where messages are silently dropped with no error returned.
These cases occur in unusual situations where either:
 1. the message type is not allowed to a virtual GPU, or
 2. a PCI recovery is underway and the HW is not yet in sync with the SW

For more details see
 commit 4ea5081c82 ("drm/amd/powerplay: enable SMC message filter")
 commit bf36b52e78 ("drm/amdgpu: Avoid accessing HW when suspending SW state")

(v2)
  Reworked with suggestions from Luben & Paul

(v3)

  Corrected error stating all messages denied on virtual GPU

3c6591e947 drm/amd/pm: drop the cache for enabled ppfeatures
The following scenarios make the driver cache for enabled ppfeatures
outdated and invalid:
  - Other tools interact with PMFW to change the enabled ppfeatures.
  - PMFW may enable/disable some features behind driver's back. E.g.
    for sienna_cichild, on gfxoff entering, PMFW will disable gfx
    related DPM features. All those are performed without driver's
    notice.
Also considering driver does not actually interact with PMFW such
frequently, the benefit brought by such cache is very limited.

6ff7fddbd1 drm/amdgpu: add support for SMU debug option
SMU firmware expects the driver maintains error context
and doesn't interact with SMU any more when SMU errors
occurred. That will aid in debugging SMU firmware issues.

Add SMU debug option support for this request, it can be
enabled or disabled via amdgpu_smu_debug debugfs file.
Use a 32-bit mask to indicate corresponding debug modes.
Currently, only one mode(HALT_ON_ERROR) is supported.
When enabled, it brings hardware to a kind of halt state
so that no one can touch it any more in the envent of SMU
errors.

The dirver interacts with SMU via sending messages. And
threre are three ways to sending messages to SMU in current
implementation. Handle them respectively as following:

1, smu_cmn_send_smc_msg_with_param() for normal timeout cases

  Halt on any error.

2, smu_cmn_send_msg_without_waiting()/smu_cmn_wait_for_response()
for longer timeout cases

  Halt on errors apart from ETIME. Otherwise this way won't work.
  Let the user handle ETIME error in such a case.

3, smu_cmn_send_msg_without_waiting() for no waiting cases

  Halt on errors apart from ETIME. Otherwise second way won't work.

== Command Guide ==

1, enable HALT_ON_ERROR mode

 # echo 0x1 > /sys/kernel/debug/dri/0/amdgpu_smu_debug

2, disable HALT_ON_ERROR mode

 # echo 0x0 > /sys/kernel/debug/dri/0/amdgpu_smu_debug

v5:
 - Use bit mask to allow more debug features.(Evan)
 - Use WRAN() instead of BUG().(Evan)

v4:
 - Set to halt state instead of a simple hang.(Christian)

v3:
 - Use debugfs_create_bool().(Christian)
 - Put variable into smu_context struct.
 - Don't resend command when timeout.

v2:
 - Resend command when timeout.(Lijo)
 - Use debugfs file instead of module parameter.

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:

5810323ba6 drm/amd/pm: Fix a bug communicating with the SMU (v5)
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.
