c7833d332e drm/amd/powerplay: avoid using pm_en before it is initialized revised
hwmgr->pm_en is initialized at hwmgr_hw_init.

during amdgpu_device_init, there is amdgpu_asic_reset that calls to
soc15_asic_reset (for V320 usecase, Vega10 asic), in which:
1) soc15_asic_reset_method calls to pp_get_asic_baco_capability (pm_en)
2) soc15_asic_baco_reset calls to pp_set_asic_baco_state (pm_en)

pm_en is used in the above two cases while it has not yet been initialized

So avoid using pm_en in the above two functions for V320 passthrough.

c9ffa427db drm/amd/powerplay: enable pp one vf mode for vega10
Originally, due to the restriction from PSP and SMU, VF has
to send message to hypervisor driver to handle powerplay
change which is complicated and redundant. Currently, SMU
and PSP can support VF to directly handle powerplay
change by itself. Therefore, the old code about the handshake
between VF and PF to handle powerplay will be removed and VF
will use new the registers below to handshake with SMU.
mmMP1_SMN_C2PMSG_101: register to handle SMU message
mmMP1_SMN_C2PMSG_102: register to handle SMU parameter
mmMP1_SMN_C2PMSG_103: register to handle SMU response

v2: remove module parameter pp_one_vf
v3: fix the parens
v4: forbid vf to change smu feature
v5: use hwmon_attributes_visible to skip sepicified hwmon atrribute
v6: change skip condition at vega10_copy_table_to_smc

9ed9203c3e drm/amd/powerplay: rv dal-pplib interface refactor powerplay part
[WHY] clarify dal input parameters to pplib interface, remove
un-used parameters. dal knows exactly which parameters needed
and their effects at pplib and smu sides.

current dal sequence for dcn1_update_clock to pplib:

1.smu10_display_clock_voltage_request for dcefclk
2.smu10_display_clock_voltage_request for fclk
3.phm_store_dal_configuration_data {
  set_min_deep_sleep_dcfclk
  set_active_display_count
  store_cc6_data --- this data never be referenced

new sequence will be:

1. set_display_count  --- need add new pplib interface
2. set_min_deep_sleep_dcfclk -- new pplib interface
3. set_hard_min_dcfclk_by_freq
4. set_hard_min_fclk_by_freq

after this code refactor, smu10_display_clock_voltage_request,
phm_store_dal_configuration_data will not be needed for rv.

[HOW] step 1: add new functions at pplib interface
      step 2: add new functions at amdgpu dm and dc

f7becf9a08 drm/amd/pp: enable power limit increase in OD mode
OverDrive mode allows users to increase the maximum SCLK and MCLK
frequencies beyond the default on the GPU. However, this may not
results in large performance gains if the GPU then runs into its TDP
power limit. This patch adds the capability to increase the power
limit of a GPU above its default maximum.

This is only allowed when overdrive is enabled in the ppfeaturemask,
since this is an overdrive feature. The TDPODLimit value from the
VBIOS describes how how much higher the TDP should be allowed to go
over its default, in percentage.

333c8d3ef2 drm/amd/powerplay: remove uncessary extra gfxoff control call
Gfxoff is already enabled in amdgpu_device_ip_set_powergating_state.
So, no need to enable it again in pp_late_init.

pp_late_init()
	error: we previously assumed 'hwmgr' could be null (see line 185)

06b18f61ee drm/amdgpu: fix CG enabling hang with gfxoff enabled
After defer the execution of clockgating enabling, at that time, gfx already
enter into "off" state. Howerver, clockgating enabling will use MMIO to access
the gfx registers, then get the gfx hung.

So here we should move the gfx powergating and gfxoff enabling behavior at the
end of initialization behind clockgating.
