Revert "drm/amdgpu/display: Replace CONFIG_DRM_AMD_DC_DCN1_0 with CONFIG_X86"

2018-08-21T19:32:28+00:00

This reverts commit 8624c3c4dbfe24fc6740687236a2e196f5f4bfb0.

We need CONFIG_DRM_AMD_DC_DCN1_0 to guard code that is using fp math.

drm/amd/display: Pass connector id when executing VBIOS CT

2018-08-13T22:29:37+00:00

[why]
Older ASICs require both phys_id and connector_id
to execute bios command table. If we are not passing the
right connector_id - it can lead to a black screen.

[how]
Set connector_obj_id when executing vbios command table

drm/amd/display: display connected to dp-1 does not light up

2018-08-06T20:57:51+00:00

[why]
for vega, dp set_panel_mode is
handled by psp firmware. dal should not program the
register again.

[how]
dal does not program panel mode.

drm/amd/display: program display clock on cache match

2018-08-06T20:57:12+00:00

[Why]
We seem to have an issue where high enough display clock
will not get set properly during S3 resume if we only
call vbios once

[How]
Expand condition of display clock programming to happen
even when cached display clock matches requested display
clock

drm/amd/display: Use calculated disp_clk_khz value for dce110

2018-08-06T19:35:25+00:00

[Why]

The calculated values for actual disp_clk_khz were ignored when
notifying pplib of the new display requirements. In order to honor DFS
bypass clocks from the hardware, the calculated value should be used.

[How]

The return value for set_dispclk is now assigned back into new_clocks
and correctly carried through into dccg->clks.phyclk_khz. When notifying
pplib of new display requirements dccg->clks.phyclk_khz is used
instead of dce.dispclk_khz. The value of dce.dispclk_khz was never
explicitly set to anything before.

A 15% higher display clock value than calculated is no longer requested
for dce110 since it now makes use of the calculated value.

Since dce112 makes use of dce110's set_bandwidth but not its
update_clocks it needs to have the value correctly carried through.

drm/amd/display: Prevent PSR from being enabled if initialization fails

2018-07-27T14:07:43+00:00

[Why]
PSR_SET command is sent to the microcontroller in order to initialize
parameters needed for PSR feature, such as telling the microcontroller
which pipe is driving the PSR supported panel. When this command is
skipped or fails, the microcontroller may program the wrong thing if
driver tries to enable PSR.

[How]
If PSR_SET fails, do not set psr_enable flag to indicate the feature is
not yet initialized.

drm/amd/display: Decouple aux from i2c

2018-07-24T20:15:50+00:00

[Why]
Aux engine is created from i2caux layer. We want to remove this layer
and use the engine directly.

[How]
Decouple aux engine from i2caux. Move aux engine related code to dce folder and use
dc resource pool to manage the engine. And use the engine functions directly
