[PATCH 19/21] drm/i915/vrr: Allow fixed_rr with pipe joiner

[PATCH 19/21] drm/i915/vrr: Allow fixed_rr with pipe joiner

[Ankit Nautiyal]

VRR with joiner is currently disabled as it still needs some work to
correctly sequence the primary and secondary transcoders. However, we can
still use VRR Timing generator in fixed refresh rate for joiner and since
it just need to program vrr timings once and does not involve changing
timings on the fly. We still need to skip the VRR and LRR for joiner.

To achieve this set vrr.in_range to 0 for joiner case, so that we do not
try VRR and LRR for the joiner case.

v2: Avoid checks for secondary pipes, where not required. (Ville)

[PATCH 00/21] Use VRR timing generator for fixed refresh rate modes

[Ankit Nautiyal]

Even though the VRR timing generator (TG) is primarily used for
variable refresh rates, it can be used for fixed refresh rates as
well. For a fixed refresh rate the Flip Line and Vmax must be equal
(TRANS_VRR_FLIPLINE = TRANS_VRR_VMAX). Beyond that, there are some
dependencies between the VRR timings and the legacy timing generator
registers.

This series is an attempt to use VRR TG for fixed refresh rate.
For platforms XE2LPD+, always go with VRR timing generator for both fixed and
variable refresh rate cases.

Rev2:
-Added support from MTL+ and for HDMI too.
-Changed VRR VSYNC programming which is required for HDMI.
-Modified vrr compute config for bigjoiner case. (Still to be tested).

Rev3:
-Start support from XE2LPD+ as MTL needs a WA to have PSR +VRR (fixed
refresh rate)
-Add changes to enable PSR with VRR with fixed refresh rate.

Rev4:
-Addressed review comments from Mitul and rebased.

Rev5:
-Avoid MSA Ignore PAR timing enable bit for fixed refresh rate
with VRR TG.
-Skip VRR compute config for HDMI connected via DP-HDMI2.1 PCON.
-Print fixed_rr along with other VRR parameters in crtc state dump.
-Rebase

Rev6:
-Refactor VRR code to have distinct modes in which VRR timing generator
can be used: VRR, FIXED_RR, CMRR.
-Bring the cmmr attributes in vrr struct.
-Remove condition flipline > vmin for LNL.
-Account for vmax being 0 based while MSA vtotal being 1 based.

Rev7:
I have added patches from series for AS SDP fixes [1] , as without panels
that support AS SDP gives a lot of issues.
There were major changes in design as discussed in last version [2].
Below are the change logs:

-Change the design to compute vrr state based on actual uapi.vrr.enable
knob. So when that knob is disabled we always compute vmin=flipline=vmax.
-Always set vmin=crtc_vtotal instead of the using the current refresh rate
based approach. This helps to have the same guardband while switching
between fixed and variable timings.
-Disable CMRR for now to reduce complexity while changing timings on the
fly.
-Change the state computation and add vmin/vmax/flipline reprogramming
to vrr_{enable,disable}()
-Introduce the fixed refresh mode from MTL instead of LNL.

[2] https://patchwork.kernel.org/project/intel-gfx/cover/20241111091221.2992818-1-ankit.k.nautiyal@intel.com/

Rev8:
-Addressed review comments from Ville.
-Refactored few patches.
-Dropped patches:
1. "drm/i915/vrr: Adjust Vtotal for MSA for fixed timing"
2. "drm/i915/vrr: Avoid sending PUSH when VRR TG is used with Fixed
refresh rate"

Rev9:
-Fixed issue seen on BAT bugs.

Rev10:
-Drop patch for avoiding VRR for DP with HDMI panel.
-Address comments from Ville.
-Add VRR compute config for DP MST.
-Add HAS_VRR() checks and compute fixed timing for all VRR supporting
platforms.
-Move guardband and pipeline_full checks
out from the pure !fastset block in intel_pipe_config_compare().

Rev11:
-Addressed comments from Ville.
-Added only fixed_rr for Joiner.
-Use vrr_possible() before setting fixed timings and before setting
trans_vrr_ctl.
-Split patch to remove vrr.guardband/pipeline_full from !fastset block.
-Add patch to avoid writing into Vtotal.Vtotal bits when always using
VRRTG.

Rev12:
-Address comments from Ville.
-Change sequence of Disable VRR.
-Enable Push before VRR Enable.
-Clear Push after VRR Disable.
-Drop patch to remove Vtotal.vtotal bits.

Rev13:
-Reset trans_vrr_ctl in disable transcoder path.
-Do not allow vrr.guardband live programming without modeset for
platform that always have VRR TG on.

[PATCH 04/21] drm/i915/vrr: Disable CMRR

[Ankit Nautiyal]

Switching between variable and fixed timings is possible as for that we
just need to flip between VRR timings. However for CMRR along with the
timings, few other bits also need to be changed on the fly, which might
cause issues. So disable CMRR for now, till we have variable and fixed
timings sorted out.

[PATCH 06/21] drm/i915/vrr: Use crtc_vtotal for vmin

[Ankit Nautiyal]

To have fixed refresh rate with VRR timing generator the
guardband/pipeline full can't be programmed on the fly. So we need to
ensure that the values satisfy both the fixed and variable refresh
rates.

Since we compute these value based on vmin, lets set the vmin to
crtc_vtotal for both fixed and variable timings instead of using the
current refresh rate based approach. This way the guardband remains
sufficient for both cases.

v2: Avoid using vblank delay while computing vtotal, as this comes into
the picture later. (Ville)

[PATCH 07/21] drm/i915/vrr: Prepare for fixed refresh rate timings

[Ankit Nautiyal]

Currently we always compute the timings as if vrr is enabled.
With this approach the state checker becomes complicated when we
introduce fixed refresh rate mode with vrr timing generator.

To avoid the complications, instead of always computing vrr timings, we
compute vrr timings based on uapi.vrr_enable knob.
So when the knob is disabled we always compute vmin=flipline=vmax.

v2: Use actual timings without any adjustments while preparing for
fixed timings in compute_config. (Ville)
v3: Avoid setting fixed timings if !vrr_possible().
v4: Move vmin adjustement after all other timings are complete. (Ville)

[PATCH 08/21] drm/i915/display: Enable MSA Ignore Timing PAR only when in not fixed_rr mode

[Ankit Nautiyal]

MSA Ignore Timing PAR enable is set in the DP sink when we enable variable
refresh rate.

Currently for link training we depend on flipline to decide whether we
want to ignore the msa timings. With fixed refresh rate we will still
fill the flipline in all cases whether panel supports VRR or not.

Change the condition for link training to ignore the msa timings if
vrr.in_range.

v2: Add more documentation and a #TODO for readout of vrr.in_range.

Currently VRR is not supported with HDMI, but we can still leverage
the VRR Timing Generator to achieve a fixed refresh rate.
Call intel_vrr_compute_config() for HDMI which will handle the vrr
timings to have fixed refresh rate with VRR Timing Generator.

[PATCH 10/21] drm/i915/dp_mst: Use VRR Timing generator for DP MST for fixed_rr

[Ankit Nautiyal]

Currently the variable timings are supported only for DP and eDP and not
for DP MST. Call intel_vrr_compute_config() for MST which will configure
fixed refresh rate timings irrespective of whether VRR is supported or
not. Since vrr_capable still doesn't have support for DP MST this will be
just treated as non VRR case and vrr.vmin/vmax/flipline will be all set
to adjusted_mode->crtc_vtotal.

This will help to move away from the legacy timing generator and
always use VRR timing generator by default.

continue even for panels that do not support VRR.

To achieve this, refactor the condition for computing vmax and

not support VRR.

[PATCH 15/21] drm/i915/display: Use fixed_rr timings in modeset sequence

[Ankit Nautiyal]

During modeset enable sequence, program the fixed timings, and turn on the
VRR Timing Generator (VRR TG) for platforms that always use VRR TG.

For this intel_vrr_set_transcoder now always programs fixed timings.
Later if vrr timings are required, vrr_enable() will switch
to the real VRR timings.

For platforms that will always use VRR TG, the VRR_CTL Enable bit is set
and reset in the transcoder enable/disable path.

v2: Update intel_vrr_set_transcoder_timings for fixed_rr.
v3: Update intel_set_transcoder_timings_lrr for fixed_rr. (Ville)
v4: Have separate functions to enable/disable VRR CTL
v5:
-For platforms that do not always have VRRTG on, do write bits other
than enable bit and also use write the TRANS_VRR_PUSH register. (Ville)
-Avoid writing trans_ctl_vrr if !vrr_possible().
v6:
-Disable VRR just before intel_ddi_disable_transcoder_func(). (Ville)
-Correct the sequence of configuring PUSH and VRR Enable/Disable. (Ville)
v7: Reset trans_vrr_ctl to 0 unconditionally in
intel_vrr_transcoder_disable(). (Ville)

[PATCH 16/21] drm/i915/vrr: Use fixed timings for platforms that support VRR

[Ankit Nautiyal]

For fixed refresh rate use fixed timings for all platforms that support
VRR. For this add checks to avoid computing and reading VRR for
platforms that do not support VRR.

v2: Avoid touching check for VRR_CTL_FLIP_LINE_EN. (Ville)
v3: Avoid redundant statements in vrr_{compute/get}_config. (Ville)

[PATCH 18/21] drm/i915/display: Move vrr.guardband/pipeline_full out of !fastset block

[Ankit Nautiyal]

Since the vrr.guardband can now change for platforms that always use the
VRR Timing Generator, and it is unsafe to reprogram the guardband on the
fly, move the guardband and pipeline_full checks from the pure !fastboot
path and add a check for intel_vrr_always_use_vrr_tg().

For older platforms the vrr.guardband change happens when VRR Timing
generator is off. For the platforms that always use the VRR Timing
Generator, this will prevent reprogramming the vrr.guardband without a
full modeset. However, this will disrupt LRR functionality for these
platforms.

v2: modify the check to avoid breaking the LRR on older platform.

[PATCH 19/21] drm/i915/vrr: Allow fixed_rr with pipe joiner

[Ankit Nautiyal]

VRR with joiner is currently disabled as it still needs some work to
correctly sequence the primary and secondary transcoders. However, we can
still use VRR Timing generator in fixed refresh rate for joiner and since
it just need to program vrr timings once and does not involve changing
timings on the fly. We still need to skip the VRR and LRR for joiner.

To achieve this set vrr.in_range to 0 for joiner case, so that we do not
try VRR and LRR for the joiner case.

v2: Avoid checks for secondary pipes, where not required. (Ville)

[Ankit Nautiyal]

Currently VRR timing generator is used only when VRR is enabled by
userspace for sinks that support VRR. From MTL+ gradually move away from
the older timing generator and use VRR timing generator for both variable

This check is redundant due to the vrr.enable check above.

I think we might want this just for ptl for now because otherwise
we lose the LRR fastset.

Or do we know MTL/LNL having actual issues with the legacy timing
generator?

I think there was some kind of claim of issues on PTL, but dunno
if even those were real or imagined?

For MTL/LNL there are no issues, that I know of, with the legacy timing 
generator.

As you said, for PTL there were some concerns during debug of some 
issues, that were attributed to the fact that legacy timing generator 
was still used,

but even those were later root caused to other things as far as I know.

However GOP and other components like DMC fw, pre-si, etc, have 
transitioned to VRR Timing Generator as per HW recommendation,

so perhaps we can have this for PTL for now to avoid clash/issues due to 
mismatches with these.

We still need to rethink the LRR fastset as you have highlighted. Will 
add a note for this in commit message too.


Thanks for the review comments, feedback and the guidance. I will 
address the remaining things and send the revised patches.

Ankit

Hi Ville,

It seems for some case where after boot we don't do a full modeset, 
intel_vrr_transcoder_enable() doesnt get called and trans_vrr_ctl doesnt 
get filled.

I guess other VRR registers get written, but since we check 
VRR_TRANS_CTL.VRR_CTL_FLIP_LINE_EN before reading these registers, we 
are not reading those and getting a state mismatch.

e.g. : 
https://intel-gfx-ci.01.org/tree/drm-tip/Patchwork_134383v13/bat-rplp-1/igt@i915_module_load@load.html

I think we are missing to write trans_vrr_ctl in fastset path for 
platform. I still need to look why is this showing up in this particular 
platform and config.

Regards,

Ankit
