v2: - Add patch 0003 to check whether vbios can support OD
    - Add patch 0004 to disable OD feature on CI/Iceland temporary
    - Check clk against OverDrive limits from VBIOS
    - Check voltage between level0 - 2000mV
    - Set OD flag when user commit the setting
    - Print the right clk/voltage range when user's setting out of range
    - refine OD flag's update when set power state

OD feature is disabled by default.
can be enabled by module parameter
ppfeaturemask=0x7fff
(ppfeaturemask default value is 0x3fff)

Add new sysfs pp_od_clk_voltage.

cat pp_od_clk_voltage output as
OD_SCLK: 
0:        300Mhz        800 mV
1:        466Mhz        818 mV
2:        751Mhz        824 mV
3:       1019Mhz        987 mV
4:       1074Mhz       1037 mV
5:       1126Mhz       1087 mV
6:       1169Mhz       1137 mV
7:       1206Mhz       1150 mV
OD_MCLK: 
0:        300Mhz        800 mV
1:       1650Mhz       1000 mV

user can change clock/voltage by 

echo "s/m level clock voltage">pp_od_clk_voltage to change the sclk/mclk clock/voltage value in od dpm table.
and
echo "c" to commit the user's setting

when need to reset to default dpm table,

echo "r" to restore the od dpm table
echo "c" to commit the setting.

the clock's range is level0-level7*1.2
the voltage range is level0-level7*1.2

Rex Zhu (7):
  drm/amd/pp: Add hwmgr interface for edit dpm table
  drm/amd/pp: Add edit/commit/show OD clock/voltage support in sysfs
  drm/amd/pp: Disable OD feature if VBIOS limits
  drm/amd/pp: Disable OD feature on CI/Iceland.
  drm/amd/pp: Implement edit_dpm_table on smu7
  drm/amd/pp: Update smu7 dpm table with OD clock/voltage
  drm/amd/pp: Add update_avfs call when set_power_state

when Overdrive voltage, need to disable AVFS.
when OverDriv engine clock, need to recalculate
AVFS voltage by disable/enable avfs feature.

Please add a commit message.  Something like:

drm/amd/pp: Disable OD feature if VBIOS limits

Check the vbios to determine whether we can enable OD.

You may want to make the messages pr_debug.  I could go either way on
that. With the commit message added:

 The logic here is a little confusing. It seems if vdd_dependency_on_mclk has vddc changes while no vddc change for vdd_dependency_on_sclk, the DPMTABLE_OD_UPDATE_VDDC flag will be cleared. Is this desired?

Do we need to reset need_update_smu7_dpm_table flag as 0 in smu7_set_power_state_tasks?

主题: [PATCH v2 7/7] drm/amd/pp: Add update_avfs call when set_power_state

when Overdrive voltage, need to disable AVFS.
when OverDriv engine clock, need to recalculate
AVFS voltage by disable/enable avfs feature.
