After fixing up some earlier patches it turns out I had to rework
the rest and improved the individual patches. There were some changes
in upstream, which meant I had to redo most of them.
The order of patches is slightly changed, the update watermark comes before
killing off wait_vblank because it has a dependency on it.
Maarten Lankhorst (14):
drm/i915: Use passed plane state for sprite planes, v3.
drm/i915: Extend DSL readout fix to BDW and SKL.
drm/i915: Do not acquire crtc state to check clock during modeset, v2.
drm/i915: Handle cdclk limits on broadwell.
drm/i915/bxt: Use the bypass frequency if there are no active pipes.
drm/i915: Update watermark related members in the crtc_state, v2.
drm/i915: Kill off intel_crtc->atomic.wait_vblank.
drm/i915: Remove intel_crtc->atomic.disable_ips.
drm/i915: Remove atomic.pre_disable_primary.
drm/i915: Remove update_sprite_watermarks.
drm/i915: Remove some post-commit members from intel_crtc->atomic.
drm/i915: Nuke fbc members from intel_crtc->atomic.
drm/i915/skl: Update watermarks before the crtc is disabled.
drm/i915/skl: Do not allow scaling when crtc is disabled.

Don't use plane->state directly, use the pointer from commit_plane.
Changes since v1:
- Fix uses of plane->state->rotation and color key to use the passed state too.
- Only pass crtc_state and plane_state to update_plane.
Changes since v2:
- Rebased.

Those platforms have the same bug as haswell, and the same fix applies to them.

Parallel modesets are still not allowed, but this will allow updating
a different crtc during a modeset if the clock is not changed.
Additionally when all pipes are DPMS off the cdclk will be lowered
to the minimum allowed.
Changes since v1:
- Add dev_priv->active_crtcs for tracking which crtcs are active.
- Rename min_cdclk to min_pixclk and move to dev_priv.
- Add a active_crtcs mask which is updated atomically.
- Add intel_atomic_state->modeset which is set on modesets.
- Commit new pixclk/active_crtcs right after state swap.

As the comment indicates this can only fail gracefully when
called from compute_config. Fortunately this is now what's happening,
so the fixme can be removed and the DRM_ERROR downgraded.

Now that pixel clock is set to 0 when there are no active pipes it's
easy to set the bypass frequency for this case.

This removes another couple of hacks from intel_crtc->atomic, and
creates proper atomic state for it.
Changes since v1:
- Rebase on top of wm changes.

By handling this after the atomic helper waits for vblanks there will
be one less wait for vblank in the atomic path.
Also get rid of the double wait_for_vblank on broadwell, looks like
it's a bug doing the vblank wait twice.

This is already handled in pre_disable_primary, disabling it twice is useless.

This can be derived from the atomic state in pre_plane_update,
which makes it more clear when it's supposed to be called.

fb_bits is useful to have in the crtc_state for cs flips later on,
so keep it alive there. The other stuff can be calculated in
post_plane_update, and aren't useful elsewhere.
Currently there's a loop in post_plane_update, this should disappear
with the changes to atomic wm's. At that point only updates to the
primary plane are important.

This leaves intel_crtc->atomic empty, so zap it as well.

On skylake some of the registers are only writable when the correct
power wells are enabled. Because of this watermarks have to be updated
before the crtc turns off, or you get unclaimed register read and write
warnings.
This patch needs to be modified slightly to apply to -fixes.

This fixes a warning when the crtc is turned off. In that case fb
will be NULL, and crtc_clock will be 0. Because the crtc is no longer
active this is not a bug, and shouldn't trigger the WARN_ON.
Also remove handling a null crtc_state, with all transitional helpers
gone this can no longer happen.

Mm. We want to do scaling checks and whatnot during DPMS. So this should
check .enabled, no?

What about the !intel_crtc check, how is that supposed to happen?

This looks messy. I would at least get rid of the "assign two things on

Not sure what the right decision would be here..
* skl max scale is lower of:
* close to 3 but not 3, -1 is for that purpose
* or
* cdclk/crtc_clock
So when multiple pipes are enabled potentially 3x scaling is allowed, but if you dpms them all off
cdclk might get set to 0. This means a previous valid amount of scaling might suddenly become invalid.
Maybe the fix is keeping 2 cdclk's, one for scaling and one for setting.
This probably needs to be addressed in patch 3/14 then, so that one needs more love.
I will resend patch 3, 4, 5 and 14 as a separate series. The other patches from this series will still work with some easily fixed rejects.

When fb == NULL. :)

As I mentioned in discussion of 14/14, patch 3 4 and 5 should be dropped from the series.

I'm guessing because until recently crtc_state wasn't really that const. :)
I agree we should constify it, but shouldn't that be in a followup patch for readability?

I think we should keep around the min required cdclk in the crtc state.
And we recalculate that one every time anything changes. Then we can
just compare it against the current cdclk after plane/crtc states have
otherwise been computed to see if we need to change the current cdclk.

What would the use be here? In that case the above formula reduces to 1<<16.
If you want to treat dpms off the same as dpms on then you need the separate cdclk's..

Judging from irc it's very likely it suffers from the same problem, but it would be nice if we had someone who could confirm. :)

I don't understand what you're saying. We need to calculate the required
cdclk based on dpms on. And that is what we must check against the
hardware limit. If we then want to optimize the dpms off case we can
just do 'cdclk = state->active ? state->cdclk : 0'. We probably want to
do that when all pipes are in dpms off. But if we have some pipes in
dpms off and some in dpms on, we may want to skip the 'active' check
for all pipes (ie. behave as all pipes are dpms on), just to avoid flicker
when some of the remaining pipes transition from dpms off to dpms on.

It won't hurt (much) if we apply this workaround and it doesn't affect
BXT, so I think we may as well apply given what we know of BXT's lineage.

I'm a bit confused as to what the value of visible_changed is supposed to be. In
the comment in intel_drv.h you wrote "plane visibility changed". But that isn't
set if the cursor plane visibility changed. If the value of this is only
relevant for cxsr, maybe it make sense to still call it disable_cxsr?

I found this a bit confusing. Sounds like you are referring to calling
intel_post_enable_update() after the call to drm_atomic_helper_wait_for_vblanks(
), except that move wasn't mentioned before. Also, the patch replaces that call
with our own wait for vblank function, so it is probably good to mention why in
the commit message.

Separate patch with more details in the commit message.

Date: Fri Jun 26 13:55:54 2015 -0700
drm/i915: Fix IPS related flicker
at which point intel_pre_disable_primary() already called hsw_disable_ips().
This patch is an exact revert of that patch, so it would be good to mention what
changed in between that makes it unnecessary. I suppose it is the fact that
everything goes through the atomic path now.

Would it be terrible if I were to disable CXSR for cursor changes too?
Else I'll rename it to disable_cxsr.

Yes, we need vblank waits around cxsr updates.

Hmm, old_primary_state is the intel_state cast of old_pri_state. Not very
descriptive. Maybe we could have a intel_atomic_get_existing_plane_state()
helper that does the cast for us. Seems like that's the end goal almost every
time we call drm_atomic_get_existing_plane_state() anyway. But I guess that can
be done later, so

Looks like the loop is gone in v2, but the commit message wasn't updated.

The comment gets a bit confusing now, since the update call is done in
intel_post_plane_update() it is a bit difficult to make the connection.

I think having all this fbc logic here makes this function hard to read. I'd
suggest moving the fbc rotation to a bool function, and then this could be
written like this:
bool turn_off = old_primary_state->visible &&
(modeset || !primary_state->visible);
if (turn_off || !fbc_supports_rotation(...))
intel_fbc_disable_crtc(crtc);
if (turn_off)
intel_pre_disable_primary(...);
Would look a bit cleaner, IMO.

Yeah but this would break things, or we'd need to keep 2 cdclk freqs globally.
One with the real frequency, the other one used for calculations in atomic.
And only when all crtc's are disabled they would differ.
In any case, when a plane is DPMS off this code won't be useful, visible = false
because the rectangle will get clipped to (0,0)x(0,0).
Saying no scaling is possible would be fine here I think, without side effects.
