[Intel-gfx] [PATCH 00/10] drm/i915: Use a bitmask for bigjoiner state tracking

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

An attempt at making the bigjoiner state tracking both smaller and
more flexible for future needs. All we really need is a bitmask of
pipes.

I also managed to fix a bunch of issues with the state copy ...
I think. It's a bit hard to know for sure since I don't have
a DSC capably  displauy so I'm just forcing the driver to spew
out DSC but obviously I can't actually see anything on the screen.

The next thing that needs fixing is the actual modset sequence
since it's still kinda terrible. Also not flexible enough for
those future needs. I'm thinking we need suck all the logic into
the encoder hooks, and let those iterate over the pipes at
approprite times. But that's for another time.

Pushed the lot here if someone wants to consume it easier:

[Intel-gfx] [PATCH 01/10] drm/i915: Flag crtc scaling_filter changes as modeset

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

The core doesn't flag scaling_filter prop changes as needing
a modeset. That doesn't work for us since we only reprogram the
pipe scaler during full modesets and fastsets. So we need to
flag the prop change as a modeset ourselves. Assuming nothing else
has changed the operation will get promoted (demoted?) to a fastset
later.

[Intel-gfx] [PATCH 02/10] drm/i915: Fix bigjoiner state copy fails

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We seem to be missing a few things from the bigjoiner state copy.
Namely hw.mode isn't getting copied (which probably causes PIPESRC
to be misconfigured), CTM/LUTs aren't getting copied (which could
cause the pipe to produced incorrect output), and we also forgot
to copy over the color_mgmt_changed flag so potentially we fail
to do the actual CTM/LUT programming (assuming we aren't doing
a full modeset or fastset). Fix it all.

[Intel-gfx] [PATCH 03/10] drm/i915: Remove weird code from intel_atomic_check_bigjoiner()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

There's some weird junk in intel_atomic_check_bigjoiner()
that's trying to look at the old crtc state's bigjoiner
usage for some reason. That code is totally unnecessary,
and maybe even actively harmful. Not entirely sure which
since it's such a mess that I can't actually wrap my brain
around what it ends up doing.

Either way, thanks to intel_bigjoiner_add_affected_crtcs()
all of the old bigjoiner crtcs are guaranteed to be in the
state already if any one of them is in the state. Also if
any one of those crtcs got flagged for a modeset, then all
of them will have been flagged, and the bigjoiner links
will have been detached via kill_bigjoiner_slave().

So there is no need to look examing any old bigjoiner
usage in intel_atomic_check_bigjoiner(). All we have to care
about is whether bigjoiner is needed for the new state,
and whether we can get the slave crtc we need.

[Intel-gfx] [PATCH 04/10] drm/i915: Clean up the bigjoiner state copy logic

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Currently the bigjoiner state copy logic is kind of
a byzantine mess.

Clean it up to operate in the following manner during a full
modeset:
1) master uapi -> hw state copy
2) master hw -> slave hw state copy

And during a non-modeset update we do:
1) master uapi -> hw state light copy
2) master hw -> slave hw state light copy

I think that is now easier to reason about since we never do
any kind of master uapi -> slave hw state copy short circuit
that could happen previously.

Obviously this does now depend on the master uapi->hw copy
always happening before the master hw -> slave hw copy, but
that is guaranteed by the fact that we always add both crtcs
to the state early, the crtcs are registered in pipe
order (so the compute_config loop happens in pipe order),
and the hardware requires the master pipe has to be lower
than the slave pipe as well. And for good measure we shall
add a check+WARN for this before doing the bigjoiner crtc
assignment.

[Intel-gfx] [PATCH 06/10] drm/i915: Introduce intel_crtc_is_bigjoiner_{slave, master}()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Introduce helpers to query whether the crtc is the slave/master
for bigjoiner. This decouples most places from the exact
state layout we use to track this relationship, allowing us
to change and extend it more easily.

[Intel-gfx] [PATCH 07/10] drm/i915: Convert for_each_intel_crtc_mask() to take a pipe mask instead

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Often using pipes is more convenient than crtc indices.
Convert the current for_each_intel_crtc_mask() to take a
pipe mask instead of a crtc index mask, and rename it to
for_each_intel_crtc_in_pipe_mask() to make it clear what
it does.

The current users of for_each_intel_crtc_mask() don't really
care which kind of mask we use, but for other uses a pipe
mask if better.

[Intel-gfx] [PATCH 10/10] drm/i915: Change bigjoiner state tracking to use the pipe bitmask

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Get rid of the inflexible bigjoiner_linked_crtc pointer thing
and just track things as a bitmask of pipes instead. We can
also nuke the bigjoiner_slave boolean as the role of the pipe
can be determined from its position in the bitmask.

It might be possible to nuke the bigjoiner boolean as well
if we make encoder.compute_config() do the bitmask assignment
directly for the master pipe. But for now I left that alone so
that encoer.compute_config() will just flag the state as needing
bigjoiner, and the intel_atomic_check_bigjoiner() is still
responsible for determining the bitmask. But that may have to change
as the encoder may be in the best position to determine how
exactly we should populate the bitmask.

Most places that just looked at the single bigjoiner_linked_crtc
now iterate over the whole bitmask, eliminating the singular
slave pipe assumption.

Because I noticed it while examining the bigjoiner state copy mess.

These *_changed flags aren't really state. They're just
ephemeral properties of the atomic transaction to indicate what
has changed since last time. I've occasionally pondered about
moving all them to  live as bitmasks in the top level 
drm_atomic_state instead to make that more clear, but haven't
actually gotten bored enough to do it. Also there are other things
hanging off the various state objects that arent really part of the
state proper either.

[Intel-gfx] [PATCH v2 02/10] drm/i915: Fix bigjoiner state copy fails

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We seem to be missing a few things from the bigjoiner state copy.
Namely hw.mode isn't getting copied (which probably causes PIPESRC
to be misconfigured), CTM/LUTs aren't getting copied (which could
cause the pipe to produced incorrect output), and we also forgot
to copy over the color_mgmt_changed flag so potentially we fail
to do the actual CTM/LUT programming (assuming we aren't doing
a full modeset or fastset). Fix it all.

v2: Fix uapi.ctm vs. hw.ctm copy-paste fail

[Intel-gfx] [PATCH v2 04/10] drm/i915: Clean up the bigjoiner state copy logic

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Currently the bigjoiner state copy logic is kind of
a byzantine mess.

Clean it up to operate in the following manner during a full
modeset:
1) master uapi -> hw state copy
2) master hw -> slave hw state copy

And during a non-modeset update we do:
1) master uapi -> hw state light copy
2) master hw -> slave hw state light copy

I think that is now easier to reason about since we never do
any kind of master uapi -> slave hw state copy short circuit
that could happen previously.

Obviously this does now depend on the master uapi->hw copy
always happening before the master hw -> slave hw copy, but
that is guaranteed by the fact that we always add both crtcs
to the state early, the crtcs are registered in pipe
order (so the compute_config loop happens in pipe order),
and the hardware requires the master pipe has to be lower
than the slave pipe as well. And for good measure we shall
add a check+WARN for this before doing the bigjoiner crtc
assignment.

So even with the bitmask approach, we still plan to have bools for bigjoiner_slave?

Is all of the above part of the commit message? Dont understand why its changing is_trans_port_sync_mode() ?

Re: [Intel-gfx] [PATCH 10/10] drm/i915: Change bigjoiner state tracking to use the pipe bitmask

Okay so trying to understand the design here:
For Pipe A + B Bigjoiner and C + D bigjoiner for example,
bitmasks will be as below:

A : 0011
B:  0011

C: 1100
D: 1100

Is this correct understanding? Because we would mark both the master pipe and slave pipe in a bitmask right?

Here we have both master and slave pipe bits set in a bitmask: This would result in ffs(0011) -1 = 2 which wouldnt be correct?

I dont get how we are checking for the invalid slave pipe here?
slave_pipes = BIT(1) = 0010
bigjoiner_pipes = 0000 (since we havents et anything in compute config)
so slave_pipes & ~bigjoiner_pipes = 0010 & 1111 = 0010 so the condition will be true
And then we are flagging it as error why?

bigjoiner_pipes() is a bitmask of pipes that support bigjoiner.
It is constant for the platform.

If we come here with eg. master == pipe D on TGL then we'd
mark the non-existent pipe E as the slave. This check will
catch that.

Nope. No longer necessary.

I had to touch that line to get coccinelle to actually do the
transformation. For some reason it refused to do anything if
I just tried to add the two new lines.

It's the same junk as in intel_crtc_prepare_cleared_state(). There's
a comment there IIRC that explains some of the historical baggage here.
We should fix this mess, but it would require some actual thought.

Okay yes sorry yes ffs finds the position of the first least significant bit so should be 1 , and then master pipe would be 0
For when its between C & D, then ffs(1100) will be 3 and master pipe would be 2 which is C so yes this makes sense now.

Okay yes makes sense, I was mistaking bigjoiner_pipes(i915) with crtc_state->bigjoiner_pipes

Okay with these calrifications,
