5 years agodrm/amd/display: update DSC MST DP virtual DPCD peer device enumeration policy
Wenjing Liu [Thu, 16 May 2019 17:01:51 +0000 (13:01 -0400)]
drm/amd/display: update DSC MST DP virtual DPCD peer device enumeration policy

[why]
Current policy assumes virtual DPCD peer device as
an individual MST branch device with 1 input and 1 output.
However this is only true for virtual DP-to-DP peer device.
In general there are three types of virtual DP peer devices.
1. Sink peer device with virtual DPCD.
2. Virtual DP-to-DP Peer device with virtual DPCD.
3. Virtual DP-to-HDMI Protocol Converter Peer Device with
Virtual DPCD.
So we should break the assumption and handle all three types.

[how]
DP-to-DP peer device will have virtual DPCD cap upstream.
Sink peer device will have virtual DPCD on the logical port.
Dp to HDMI protocol converter peer device will have virtual DPCD
on its converter port.
For DSC capable Synaptics non VGA port we workaround by enumerating
a virutal DPCD peer device on its upstream
even if it doesn't have one.

5 years agodrm/amd/display: Copy stream updates onto streams
Nicholas Kazlauskas [Tue, 14 May 2019 13:19:01 +0000 (09:19 -0400)]
drm/amd/display: Copy stream updates onto streams

[Why]
Almost every function in DC that works with stream state expects that
the current state on the stream is the one that it should be writing
out. These functions are typically triggered by specifying a particular
stream update - but the actual contents of the stream update itself
are ignored, leaving it to the DM to actually update the stream state
itself.

The problem with doing this in DM is a matter of timing. On Linux
most of this is incorrectly done in atomic check, when we actually want
it to be done during atomic commit tail while access to DC is locked.

To give an example, a commit requesting to modify color management
state for DM could come in, be rejected, but still have modified
the actual system state for the stream since it's shared memory. The
next time color management gets programmed it'll use the rejected
color management info - which might not even still be around if it's
a custom transfer function.

So a reasonable place to perform this is within DC itself and this is
the model that's currently in use for surface updates. DC can even
compare the current system state to the incoming surface update to
determine update level, something that can't currnetly be done with the
framework for stream updates.

[How]
Duplicate the framework used for surface updates for stream updates
as well. Copy all the updates after checking the update type.

drm/amd/display: Remove OPP clock programming on plane disable

[Why]
Plane disable gets calls when we enable blank. On DCN2, we blank by using
DPG to display a black colour instead of using OTG blank. DPG runs off the
OPP clock, therefore we shouldn't disable the OPP clock when disabling the

that will be addressed in a separate commit.

5 years agodrm/amd/display: Properly guard display_mode_vba with DCN2
Leo Li [Tue, 26 Mar 2019 01:11:07 +0000 (21:11 -0400)]
drm/amd/display: Properly guard display_mode_vba with DCN2

[Why]

display_mode_vba is for DCN2 and up. When building for upstream (DCN1
enabled only), there will be a build error, since display_mode_vba.c/h
is stripped out.

Note that building DCN1 only with internal dal-dev is still fine, since
display_mode_vba.h is not stripped out internally - only in upstream.
The make directives therefore stll work, and so will any #include's.

[How]

Since subsequent generations require DCN2 enabled anyways, guard the
makefile directive for display_mode_vba.o with DCN2. Guard any includes
with DCN2. In addition, guard the entire contents of display_mode_vba.h
with DCN2, to simulate the file being stripped out in upstream.

A forward declaration for 'struct display_mode_lib' also needs to be
added in display_mode_lib.h. Previously, display_mode_vba.h contained
the forward declaration, and display_mode_lib.h in turn included it.
This won't work if mode_vba.h is stripped out, requring mode_lib.h to do
so itself.

5 years agodrm/amd/display: do not power on eDP power rail early
Anthony Koo [Fri, 10 May 2019 18:57:48 +0000 (14:57 -0400)]
drm/amd/display: do not power on eDP power rail early

[Why]
Modern Standby may toggle display adapter state between D0
and D3 state unpredictably.
But events that cause transition to D0 are not always resulting
in a display light up scenario.

Modern eDP panels should be able to power on panel logic
quickly upon VDD going high. Based on spec, the T3 time
between VDD on and HPD high can be between 0 and 80 ms.

Doing any tricky sorts of optimization by powering on panel
VDD early during D0 transition on can negatively impact other
features due to unnecessary power drain and toggling when
final system state does not intend for the panel to be lit up.

We need OEMs to source higher end panels that have T3 time
close to 0 if they want quick S3/Modern Standby resume times.

[How]
Remove panel VDD power on in init_hw

5 years agodrm/amd/display: update calculated bounding box logic for NV
Jun Lei [Thu, 9 May 2019 19:32:27 +0000 (15:32 -0400)]
drm/amd/display: update calculated bounding box logic for NV

[why]
Current calculation of bounding box will cause DML to increase voltage
state due to DPP or DISPCLK, this is unnecessary since from DML perspective
we can max DPP/DISP can be supported at DPM0.  This is because
increasing voltage for DPP/DISP is done separately via actual minimum values
of DISP and DPP CLK

[how]
For each calculated state, DPP, DISP, PHY, and DSC clk should always be set to
maximum.  FCLK, SOCCLK, and DCFCLK should be based of UCLK.
