3d0e3ce52c drm/amdgpu: fix bad DMA from INTERRUPT_CNTL2
The INTERRUPT_CNTL2 register expects a valid DMA address, but is
currently set with a GPU MC address.  This can cause problems on
systems that detect the resulting DMA read from an invalid address
(found on a Power8 guest).

Instead, use the DMA address of the dummy page because it will always
be safe.

e3dd3aa8e0 drm/amd/display: Fix debugfs on MST connectors
[why]
Previous patch allowed to initialize debugfs entries on both MST
and SST connectors, but MST connectors get registered much later
which exposed an issue of debugfs entries being initialized in the
same folder.

[how]
Return SST debugfs entries' initialization back to where it was.
For MST connectors we should initialize debugfs entries in connector
register function after the connector is registered.

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.

v3: fix spelling (Alex)

We support the case that ta binary have one or multiple of

binariy's availablity before decide to upload them to psp.

In the terminate (unload) case, the driver will check the
context readiness before perform unload activity. It's fine

589b64a7e3 drm/amdgpu: add dummy read by engines for some GCVM status registers in gfx10
The GRBM register interface is now capable of bursting 1 cycle per
register wr->wr, wr->rd much faster than previous muticycle per
transaction done interface.  This has caused a problem where
status registers requiring HW to update have a 1 cycle delay, due
to the register update having to go through GRBM.

For cp ucode, it has realized dummy read in cp firmware.It covers
the use of WAIT_REG_MEM operation 1 case only.So it needs to call
gfx_v10_0_wait_reg_mem in gfx10. Besides it also needs to add warning to
update firmware in case firmware is too old to have function to realize
dummy read in cp firmware.

For sdma ucode, it hasn't realized dummy read in sdma firmware. sdma is
moved to gfxhub in gfx10. So it needs to add dummy read in driver
between amdgpu_ring_emit_wreg and amdgpu_ring_emit_reg_wait for sdma_v5_0.

365f7f8db8 drm/amdgpu: fix double reference dropping
The reference to object fence is dropped at the end of the loop.
However, it is dropped again outside the loop. The reference can be
dropped immediately after calling dma_fence_wait() in the loop and
thus the dropping operation outside the loop can be removed.

946ab8db69 drm/amdgpu: fix potential double drop fence reference
The object fence is not set to NULL after its reference is dropped. As a
result, its reference may be dropped again if error occurs after that,
which may lead to a use after free bug. To avoid the issue, fence is
explicitly set to NULL after dropping its reference.

11c6108934 drm/amdgpu: add warning for GRBM 1-cycle delay issue in gfx9
It needs to add warning to update firmware in gfx9
in case that firmware is too old to have function to
realize dummy read in cp firmware.

a6522a5c63 drm/amdgpu: add dummy read by engines for some GCVM status registers in gfx10
The GRBM register interface is now capable of bursting 1 cycle per
register wr->wr, wr->rd much faster than previous muticycle per
transaction done interface.  This has caused a problem where
status registers requiring HW to update have a 1 cycle delay, due
to the register update having to go through GRBM.

For cp ucode, it has realized dummy read in cp firmware.It covers
the use of WAIT_REG_MEM operation 1 case only.So it needs to call
gfx_v10_0_wait_reg_mem in gfx10. Besides it also needs to add warning to
update firmware in case firmware is too old to have function to realize
dummy read in cp firmware.

For sdma ucode, it hasn't realized dummy read in sdma firmware. sdma is
moved to gfxhub in gfx10. So it needs to add dummy read in driver
between amdgpu_ring_emit_wreg and amdgpu_ring_emit_reg_wait for sdma_v5_0.
