drm/amd/display: Remove dml_common_def file

2020-05-20T21:25:43+00:00

During the rework for removing the FPU issues, I found the following
warning:

 [..] dml_common_defs.o: warning: objtool: dml_round()+0x9: FPU
      instruction outside of kernel_fpu_{begin,end}()

This file has a single function that does not need to be in a specific
file. This commit drop dml_common_defs file, and move dml_round function
to dml_inline_defs.

drm/amd/display: Update DCN2.1 DV Code Revision

2020-05-05T20:07:02+00:00

[WHY & HOW]
There is a problem in hscale_pixel_rate, the bug
causes DCN to be more optimistic (more likely to underflow)
in upscale cases during prefetch.
This commit ports the fix from DV code to address these issues.

drm/amd/display: Fix dcn21 num_states

2020-03-31T16:26:15+00:00

[Why]
DML expects num_states to exclude the duplicate state.

[How]
Set num_states to correct value to prevent array off-by-one error.  Also
refactor max clock level code for diags.

drm/amd/display: change number of cursor policy for dml calculation.

2020-03-05T05:30:37+00:00

[Why]
vstartup calculation is incorrect due to use 2 number of cursors and
result in an underflow when playing video in full screen mode and
combines graphic plane and video plane.

[How]
Apply new policy for dml calculation.
1 cursor for graphic plane, 0 cursor for video plane.

drm/amd/display: Make clock table struct more accessible

2020-03-05T05:29:20+00:00

[WHY & HOW]
In order to correctly intepret clock table, num_states is also needed.
This field did not get moved with clock_table but should next to it for
easier access/viewing.

drm/amd/display: Make clock table struct more accessible

2020-02-25T16:09:44+00:00

[WHY]
Currently clock table struct is very far down in the bounding box struct
making it hard to find while debugging, especially when using the
dal3dbgext.

[HOW]
Move it up so it is the first struct defined, and therefore much easier
to find and access.

drm/amd/display: Update TTU properly

2020-02-25T16:09:25+00:00

[Why]
We need to update TTU properly if DRAMClockChangeWatermark changes. If
TTU < DRAMClockChangeWatermark, we pstate won't be allowed and we will
hang in some PSR cases.

[How]
Update TTU if DramClockChangeWatermark value increases (only if TTU was
dependent on the watermark value on the DRAMClockChangeWatermark value
in the first place).
