2 years agodrm/amd/display: Prevent OTG shutdown during PSR SU
Leo Li [Mon, 26 Sep 2022 21:53:55 +0000 (17:53 -0400)]
drm/amd/display: Prevent OTG shutdown during PSR SU

[Why]

Enabling Z10 optimizations allows DMUB to disable the OTG during PSR
link-off. This theoretically saves power by putting more of the display
hardware to sleep. However, we observe that with PSR SU, it causes
visual artifacts, higher power usage, and potential system hang.

This is partly due to an odd behavior with the VStartup interrupt used
to signal DRM vblank events. If the OTG is toggled on/off during a PSR
link on/off cycle, the vstartup interrupt fires twice in quick
succession. This generates incorrectly timed vblank events.
Additionally, it can cause cursor updates to generate visual artifacts.

Note that this is not observed with PSR1 since PSR is fully disabled
when there are vblank event requestors. Cursor updates are also
artifact-free, likely because there are no selectively-updated (SU)
frames that can generate artifacts.

[How]

A potential solution is to disable z10 idle optimizations only when fast
updates (flips & cursor updates) are committed. A mechanism to do so
would require some thoughtful design. Let's just disable idle
optimizations for PSR2 for now.

drm/amd/display: Fix various dynamic ODM transitions on DCN32

[Why&How]

Several transitions were fixed that will allow Dynamic ODM and MPO
transitions to be supported on DCN32.

1) Due to resource limitations, in certain scenarios that require an MPO
plane to be split, the features cannot be combined with the current
policy. This is due to unsafe transitions being required (OPP instance
per MPCC being switched on active pipe is not supported by DCN), to
support the split plane with ODM active as it moves across the viewport.
Dynamic ODM will now be disabled when MPO is required.

2) When exiting MPO and re-entering ODM, DC assigns an inactive pipe for
the next ODM pipe, which under previous power gating policy would result
in programming a gated DSC HW block. New policy dynamically
gates/un-gates DSC blocks when Dynamic ODM is active to support

transitions on DCN32 only.

3) Entry and exit from 3 plane MPO and Dynamic ODM requires a minimal
transition so that all pipes which require their MPCC OPP instance to
be changed have a full frame to be disabled before reprogramming. To
solve this, the Dynamic ODM policy now utilizes minimal state
transitions when entering or exiting 3 plane scenarios.

4) Various fixes to DCN32 pipe merge/split algorithm to support Dynamic
ODM and MPO transitions.

In summary, this commit fixes various transitions to support ODM->MPO
and MPO->ODM.

drm/amd/display: fill in clock values when DPM is not enabled

[Why]
For individual feature testing, PMFW may not report all clock
values back. Driver will default them to 0 but this will
cause the BB table to be skipped and default to one state
with max clocks.

[How]
Add helper function to scan through initial clock values and
populate them with default clock limits so that BB table
can be built.
Add dpm_enabled flag to check when DPM is not enabled and
to trigger helper function.

2 years agodrm/dp: Don't rewrite link config when setting phy test pattern
Khaled Almahallawy [Fri, 16 Sep 2022 05:49:00 +0000 (22:49 -0700)]
drm/dp: Don't rewrite link config when setting phy test pattern

The sequence for Source DP PHY CTS automation is [2][1]:
1- Emulate successful Link Training(LT)
2- Short HPD and change link rates and number of lanes by LT.
(This is same flow for Link Layer CTS)
3- Short HPD and change PHY test pattern and swing/pre-emphasis
levels (This step should not trigger LT)

The problem is with DP PHY compliance setup as follow:

     [DPTX + on board LTTPR]------Main Link--->[Scope]
                    ^                         |
|                         |
|                         |
----------Aux Ch------>[Aux Emulator]

At step 3, before writing TRAINING_LANEx_SET/LINK_QUAL_PATTERN_SET
to declare the pattern/swing requested by scope, we write link
config in LINK_BW_SET/LANE_COUNT_SET on a port that has LTTPR.
As LTTPR snoops aux transaction, LINK_BW_SET/LANE_COUNT_SET writes
indicate a LT will start [Check DP 2.0 E11 -Sec 3.6.8.2 & 3.6.8.6.3],
and LTTPR will reset the link and stop sending DP signals to
DPTX/Scope causing the measurements to fail. Note that step 3 will
not trigger LT and DP link will never recovered by the
Aux Emulator/Scope.

The reset of link can be tested with a monitor connected to LTTPR
port simply by writing to LINK_BW_SET or LANE_COUNT_SET as follow

  igt/tools/dpcd_reg write --offset=0x100 --value 0x14 --device=2

OR

  printf '\x14' | sudo dd of=/dev/drm_dp_aux2 bs=1 count=1 conv=notrunc
  seek=$((0x100))

This single aux write causes the screen to blank, sending short HPD to
DPTX, setting LINK_STATUS_UPDATE = 1 in DPCD 0x204, and triggering LT.

As stated in [1]:
"Before any TX electrical testing can be performed, the link between a
DPTX and DPRX (in this case, a piece of test equipment), including all
LTTPRs within the path, shall be trained as defined in this Standard."

In addition, changing Phy pattern/Swing/Pre-emphasis (Step 3) uses the
same link rate and lane count applied on step 2, so no need to redo LT.

The fix is to not rewrite link config in step 3, and just writes
TRAINING_LANEx_SET and LINK_QUAL_PATTERN_SET
