drm/amd/powerplay: Enable/Disable NBPSTATE on On/OFF of UVD

2018-11-21T08:19:25+00:00

commit 51ef434a15b450bfbef1e06cc87ee4e98a224486 upstream.

We observe black lines (underflow) on display when playing a
4K video with UVD. On Disabling Low memory P state this issue is
not seen.
Multiple runs of power measurement shows no imapct.

drm/amdgpu: Suppress keypresses from ACPI_VIDEO events

2018-11-21T08:19:25+00:00

commit 582f58de36834096a91cc1de2540c2f7269f850d upstream.

Currently we return NOTIFY_DONE for any event which we don't think is
ours. However, many laptops will send more then just an ATIF event and
will also send an ACPI_VIDEO_NOTIFY_PROBE event as well. Since we don't
check for this, we return NOTIFY_DONE which causes a keypress for the
ACPI event to be propogated to userspace. This is the equivalent of
someone pressing the display key on a laptop every time there's a
hotplug event.

So, check for ACPI_VIDEO_NOTIFY_PROBE events and suppress keypresses
from them.

drm/amdgpu: add missing CHIP_HAINAN in amdgpu_ucode_get_load_type

2018-11-21T08:19:25+00:00

commit d9997b64c52b70bd98c48f443f068253621d1ffc upstream.

This caused a confusing error message, but there is functionally
no problem since the default method is DIRECT.

drm/amdgpu: fix integer overflow test in amdgpu_bo_list_create()

2018-11-21T08:19:12+00:00

[ Upstream commit ff30e9e8509cb877dc7cbc776b36c70f5bdd290f ]

We accidentally left out the size of the amdgpu_bo_list struct.  It
could lead to memory corruption on 32 bit systems.  You'd have to
pick the absolute maximum and set "num_entries == 59652323" then size
would wrap to 16 bytes.

drm/amdgpu: Fix SDMA TO after GPU reset v3

2018-11-21T08:19:11+00:00

[ Upstream commit d8de8260a45aae8f74af77eae9a162bdc0ed48d2 ]

After GPU reset amdgpu_vm_clear_bo triggers VM flush
but job->vm_pd_addr is not set causing SDMA TO.

v2:
Per advise by Christian König avoid flushing VM for jobs where
job->vm_pd_addr wasn't explicitly set.

v3:
Shortcut vm_flush_needed early.

drm/amd/display: fix gamma not being applied

2018-11-21T08:19:10+00:00

[ Upstream commit 30049754ab7c4b6148dd3cd64af7d54850604582 ]

[WHY]
Previously night light forced a full update by
applying a  transfer function update regardless of if it was changed.
This logic was removed,

Now gamma surface updates are only applied when there is also a plane
info update, this does not work in cases such as using the night light
slider.

[HOW]
When moving the night light slider we will perform a full update if
the gamma has changed and there is a surface, even when the surface
has not changed. Also get stream updates in setgamma prior to
update planes and stream.

drm/amd/display: Raise dispclk value for dce120 by 15%

2018-11-21T08:19:10+00:00

[ Upstream commit 481f576c6c21bf0446eaa23623ef0262e9a5387c ]

[Why]

The DISPCLK value was previously requested to be 15% higher for all
ASICs that went through the dce110 bandwidth code path. As part of a
refactoring of dce_clocks and the dce110 set bandwidth codepath this
was removed for power saving considerations.

That change caused display corruption under certain hardware
configurations with Vega10.

[How]

The 15% DISPCLK increase is brought back but only on dce110 for now.
This is should be a temporary workaround until the root cause is sorted
out for why this occurs on Vega (or other ASICs, if reported).

drm/amd/display: fix bug of accessing invalid memory

2018-11-21T08:19:08+00:00

[ Upstream commit 43c3ff27a47d83d153c4adc088243ba594582bf5 ]

[Why]
A loop inside of build_evenly_distributed_points function that traverse through
the array of points become an infinite loop when m_GammaUpdates does not
get assigned to any value.

[How]
In DMColor, clear m_gammaIsValid bit just before writting all Zeromem for
m_GammaUpdates, to prevent calling build_evenly_distributed_points
before m_GammaUpdates gets assigned to some value.
