fa7041d9d2 drm/amd/display: Fix ineffective setting of max bpc property
[Why]
Regression was introduced where setting max bpc property has no effect
on the atomic check and final commit. It has the same effect as max bpc
being stuck at 8.

[How]
Correctly propagate max bpc with the new connector state.

5ae9c378c3 drm/amd/display: Enable output_bpc property on all outputs
[Why]
Connector property output_bpc is available on DP/eDP only. New IGT tests
would benifit if this property works on HDMI.

[How]
Enable this read-only property on all types of connectors.

cdaae8371a drm/amd/display: Handle GPU reset for DC block
[Why]
Previously we used the s3 codepath for gpu reset. This can lead to issues in
certain case where we end of waiting for fences which will never come (because
parts of the hw are off due to gpu reset) and we end up waiting forever causing
a deadlock.

[How]
Handle GPU reset separately from normal s3 case. We essentially need to redo
everything we do in s3, but avoid any drm calls.

For GPU reset case

suspend:
	-Acquire DC lock
	-Cache current dc_state
	-Commit 0 stream/planes to dc (this puts dc into a state where it can be
	 powered off)
	-Disable interrupts
resume
	-Edit cached state to force full update
	-Commit cached state from suspend
	-Build stream and plane updates from the cached state
	-Commit stream/plane updates
	-Enable interrupts
	-Release DC lock

v2:
-Formatting
-Release dc_state

cbd14ae7ea drm/amd/display: Fix incorrectly pruned modes with deep color
[Why]
When "max bpc" is set to enable deep color, some modes are removed from
the list if they fail validation on max bpc. These modes should be kept
if they validates fine with lower bpc.

[How]
- Retry with lower bpc in mode validation.
- Same in atomic commit to apply working bpc, not necessarily max bpc.

8a791dabea drm/amd/display: Add DC Debug mask to disable features for bringup
[Why]
At bringup we want to be able to disable various power features.

[How]
These features are already exposed as dc_debug_options and exercised
on other OSes. Create a new dc_debug_mask module parameter and expose
relevant bits, in particular
 * DC_DISABLE_PIPE_SPLIT
 * DC_DISABLE_STUTTER
 * DC_DISABLE_DSC
 * DC_DISABLE_CLOCK_GATING

2346ef47e8 drm/amd/display: Fix vblank and pageflip event handling for FreeSync
[Why]
We're sending the drm vblank event a frame too early in the case where
the pageflip happens close to VUPDATE and ends up blocking the signal.

The implementation in DM was previously correct *before* we started
sending vblank events from VSTARTUP unconditionally to handle cases
where HUBP was off, OTG was ON and userspace was still requesting some
DRM planes enabled. As part of that patch series we dropped VUPDATE
since it was deemed close enough to VSTARTUP, but there's a key
difference betweeen VSTARTUP and VUPDATE - the VUPDATE signal can be
blocked if we're holding the pipe lock.

There was a fix recently to revert the unconditional behavior for the
DCN VSTARTUP vblank event since it was sending the pageflip event on
the wrong frame - once again, due to blocking VUPDATE and having the
address start scanning out two frames later.

The problem with this fix is it didn't update the logic that calls
drm_crtc_handle_vblank(), so the timestamps are totally bogus now.

[How]
Essentially reverts most of the original VSTARTUP series but retains
the behavior to send back events when active planes == 0.

Some refactoring/cleanup was done to not have duplicated code in both
the handlers.

Fixes: 16f17eda8b ("drm/amd/display: Send vblank and user events at vsartup for DCN")
Fixes: 3a2ce8d66a ("drm/amd/display: Disable VUpdate interrupt for DCN hardware")

1cfbbddead drm/amd/display: add addition dc type to translate to dmub fw type
[Why]
For a type like PSR version, it makes sense for most of the code
to include a dc type, instead of having this a fw type define since
this is a capability and type exposed by dc.

Especially if it doesn't even need to communicate with the fw.

The code that is packing the firmware command message
should be the one who needs to translate the psr version
into a command that the firmware understands.

Add a dc_psr_version enum.

87b7ebc2e1 drm/amd/display: Fix green screen issue after suspend
[why]
We have seen a green screen after resume from suspend in a Raven system
connected with two displays (HDMI and DP) on X based system. We noticed
that this issue is related to bad DCC metadata from user space which may
generate hangs and consequently an underflow on HUBP. After taking a
deep look at the code path we realized that after resume we try to
restore the commit with the DCC enabled framebuffer but the framebuffer
is no longer valid.

[how]
This problem was only reported on Raven based system and after suspend,
for this reason, this commit adds a new parameter on
fill_plane_dcc_attributes() to give the option of disabling DCC
programmatically. In summary, for disabling DCC we first verify if is a
Raven system and if it is in suspend; if both conditions are true we
disable DCC temporarily, otherwise, it is enabled.

d1ebfdd8d0 drm/amd/display: Unify psr feature flags
[Why]
As it stands, psr has feature flags in dm, stream, and link. Most are
not defined well enough, and different dm layers have different uses for
these same flags.

[How]
We define a new structure called psr_settings in dc_link that will hold
the following psr feature flags:

psr_feature_enable - psr is supported
psr_allow_active - psr is currently active
psr_version - internal psr version supported
psr_frame_capture_indication_req
psr_sdp_transmit_line_num_deadline
The last two flags were moved out of the power module
for the purposes of consolidating psr flags.
Their use is already well-defined.

Psr caps reported by sink will also be stored in dc_link,
in dpcd_caps.psr_caps.
