[PATCH v3 0/5] Panel replay phase1 implementation

[Animesh Manna]

Panel Replay is a power saving feature for DP 2.0 monitor and similar
to PSR on EDP.

These patches are basic enablement patches and reused psr
framework to add panel replay related new changes which
may need further fine tuning to fill the gap if there is any.

Note: The patches are not tested due to unavailability of monitor

Animesh Manna (5):
  drm/i915/panelreplay: dpcd register definition for panelreplay
  drm/i915/panelreplay: HAS_PR() macro added for panel replay
  drm/i915/panelreplay: Initializaton and compute config for panel

  drm/i915/panelreplay: enable/disable panel replay
  drm/i915/panelreplay: Added state checker for panel replay state

Missing bit 1, that is very important when panel do not support selective update panel replay needs to act like PSR1 when it is sets it needs to act
like PSR2.

All other bits are also important, for the errors ones we have PSR counter parts and your are missing the error status register.

[PATCH v3 2/5] drm/i915/panelreplay: HAS_PR() macro added for panel replay

[Animesh Manna]

Platforms having Display 13 and above will support panel
replay feature of DP 2.0 monitor. Added a HAS_PR() macro
to check for panel replay capability.

v1: Initial version.
v2: DISPLAY_VER macro used instead of has_pr flag. [Jose]
v3: HAS_PR renamed to HAS_PANEL_REPLAY. [Jani]

[PATCH v3 3/5] drm/i915/panelreplay: Initializaton and compute config for panel replay

[Animesh Manna]

As panel replay feature similar to PSR feature of EDP panel, so currently
utilized existing psr framework for panel replay.

v1: RFC version.
v2: optimized code, pr_enabled and pr_dpcd variable removed. [Jose]
v3:
- code comments improved. [Jani]
- dpcd_readb used instead of dpcd_read. [Jani]
- panel-repaplay init/compute functions moved inside respective psr
function. [Jani]

[Intel-gfx] [PATCH v3 3/5] drm/i915/panelreplay: Initializaton and compute config for panel replay

[Animesh Manna]

As panel replay feature similar to PSR feature of EDP panel, so currently
utilized existing psr framework for panel replay.

v1: RFC version.
v2: optimized code, pr_enabled and pr_dpcd variable removed. [Jose]
v3:
- code comments improved. [Jani]
- dpcd_readb used instead of dpcd_read. [Jani]
- panel-repaplay init/compute functions moved inside respective psr
function. [Jani]

have you checked if the other PSR are needed for panel replay? what about the psr2 checks? when using panel replay selective update some additional
tests will be needed regarding granularity...

mutex initialization is not executed, workers not initialized...
please go more carefully trough every PSR function and check what are the panel replay implications

We can drop this and reuse current ones ones, see bellow.

move this closer to has_psr and set both when it is panel replay.
otherwise psr functions will not be executed for panel replay, see CAN_PSR().

AFIU Panel replay do not have any dependency with PSR.
So that’s why I have created separate function for panel replay which is doing similar thing whatever needed for panel replay.
For example intel_panel_replay_compute_config() can be independent of intel_psr_compute_config().
Do you see any dependency with PSR for panel replay?

As mentioned above I understood panel replay do not have any dependency with PSR.
Will not target panel replay selective update for dg2.

Tried to double check once more.
Currently as per bspec and dp 2.0 spec did not see any dependency with PSR.
Not sure if we really need worker thread to enter in panel replay mode unlike psr where we need to wait for few idle frames.
Any suggestion/input will be helpful here.

AFIU Panel replay do not have any dependency with PSR.
So that’s why I have created separate function for panel replay which is doing similar thing whatever needed for panel replay.
For example intel_panel_replay_compute_config() can be independent of intel_psr_compute_config().
Do you see any dependency with PSR for panel replay?

There is no dependency but panel replay is PSR for DP so we should re-use PSR code as much as possible.

eDP + sink_support = PSR
DP + sink_support = panel replay

So we can reuse has_psr and all other stuff.

There is no dependency but panel replay is PSR for DP so we should re-use PSR code as much as possible.

eDP + sink_support = PSR
DP + sink_support = panel replay

So we can reuse has_psr and all other stuff.
