c2a801af31 amd/amdgpu/sriov enable onevf mode for ARCTURUS VF
Before, initialization of smu ip block would be skipped
for sriov ASICs. But if there's only one VF being used,
guest driver should be able to dump some HW info such as
clks, temperature,etc.

To solve this, now after onevf mode is enabled, host
driver will notify guest. If it's onevf mode, guest will
do smu hw_init and skip some steps in normal smu hw_init
flow because host driver has already done it for smu.

With this fix, guest app can talk with smu and dump hw
information from smu.

v2: refine the logic for pm_enabled.Skip hw_init by not
changing pm_enabled.
v3: refine is_support_sw_smu and fix some indentation

73abde4d86 drm/amdgpu/smu_v11: Unify and fix power limits
[Why]
On Navi10, and presumably arcterus, updating pp_table via sysfs would
not re-scale the maximum possible power limit one can set. On navi10,
the SMU code ignored the power percentage overdrive setting entirely,
and would not allow you to exceed the default power limit at all.

[How]
Adding a function to the SMU interface to get the pptable version of the
default power limit allows ASIC-specific code to provide the correct
maximum-settable power limit for the current pptable.

pptable definition on pcie dpm:
0 -> pcie gen speed:1, pcie lanes: *16
1 -> pcie gen speed:4, pcie lanes: *16
Then if we have a system only have the capbility:
pcie gen speed: 3, pcie lanes: *8,
we will override dpm 1 to pcie gen speed 3, pcie lanes *8.
But the code skips the dpm 0 configuration.
So the real pcie dpm parameters are:
0 -> pcie gen speed:1, pcie lanes: *16
1 -> pcie gen speed:3, pcie lanes: *8
Then the wrong pcie lanes will be toggled.

ea6d8811f1 drm/amd/powerplay: Fix error handling in smu_init_fb_allocations()
The error handling is off by one.  We should not free the first
"tables[i].bo" without decrementing "i" because that might result in a
double free.  The second problem is that when an error occurs, then the
zeroth element "tables[0].bo" isn't freed.

I had make "i" signed int for the error handling to work, so I just
updated "ret" as well as a clean up.
