[PATCH 0/8] acquire ctx for everyone!

[PATCH 0/8] acquire ctx for everyone!

[Daniel Vetter]

Hi all,

This is the final bits of my cleanup work to get rid of the implicit acquire
context for atomic drivers. This handles the property stuff by essentially just
ripping it all out, after 20+ drivers I don't see any need for a driver to
overwrite anything here. Except omapdrm, and that is handled within the existing
framework already.

Besides removing a pile of code another upshot of this work is that a
set_property call for atomic driver now only takes the locks it needs, the same
way like the atomic ioctl.

Leftover bits (I should probably put them into a todo.rst entry):
- Convert vmwgfx over to the fbdev helpers since their current hand-rolled ones
  get this all wrong.

- Add an explicit acquire_ctx to drm_modeset_(un)lock_all and nuke the
  GFP_ATOMIC allocation.

- Also clean up the get_property paths a bit more, would be nice if we wouldn't
  need to have to take all the locks for atomic drivers.

But already with this we're guaranteed that all core and helper paths pass
around the acquire_ctx correctly, which means drivers can now start to use their
own internal drm_modeset_locks for private data structures.

Cheers, Daniel

[PATCH 1/8] drm/omap: Simplify the rotation-on-crtc hack

[Daniel Vetter]

I want/need to rework the core property handling, and this hack is
getting in the way. But since it's a non-standard propety only used by
legacy userspace we know that this will only every be called from
ioctl code. And never on some other free-standing state struct, where
this old hack wouldn't work either.

v2: don't forget zorder and get_property!

acquire_ctx for crtc's getprop too then?

The comment about read lock is only valid when the plane is bound to the crtc. In general this is not always the case.
You can only peak at plane->state when crtc->state->plane_mask & BIT(drm_plane_index(plane)) is true.

I think we might need -EDEADLK handling for getprop then, even though it's not optimal. :(

Well both the old an new way only worked because we grab all the locks
unconditionally. And I'd really want to avoid get_prop being anything
but a simple lookup. Unfortuantely that breaks omapdrm, so no idea
what exactly to do here.

In a way adding properties without standardizing them across drivers
first was a really bad idea, because then we have disjoint sets of
uapi expectations, and there's just no way to make that work.

I guess one radical approach might be to make this the "standard", and
just redirect rotation from the CRTC to the primary plane.

Or omapdrm needs to duplicate the property properly, and update one if
the other is set. I think that's probably the most workable approach.

Maybe the first question we should answer is whether this hack is still needed 
in the omapdrm driver. Tomi, do you know whether userspace still needs this ?

The omap X driver uses legacy modesetting and the rotation property for
the crtc.

[PATCH] drm/omap: Rework the rotation-on-crtc hack

[Daniel Vetter]

I want/need to rework the core property handling, and this hack is
getting in the way. But since it's a non-standard propety only used by
legacy userspace we know that this will only every be called from
ioctl code. And never on some other free-standing state struct, where
this old hack wouldn't work either.

v2: don't forget zorder and get_property!

v3: Shadow the legacy state to avoid locking issues in get_property
(Maarten).

Nitpicking, you can reformat the comment to go towards the 80 columns limit.

No need to copy the zpos and rotation fields ?

Could you please define this structure in omap_crtc.c, as it's internal to the 
CRTC handling code ?

[PATCH] drm/omap: Rework the rotation-on-crtc hack

[Daniel Vetter]

I want/need to rework the core property handling, and this hack is
getting in the way. But since it's a non-standard propety only used by
legacy userspace we know that this will only every be called from
ioctl code. And never on some other free-standing state struct, where
this old hack wouldn't work either.

v2: don't forget zorder and get_property!

v3: Shadow the legacy state to avoid locking issues in get_property
(Maarten).

v4: Review from Laurent
- Move struct omap_crtc_state into omap_crtc.c
- Clean up comments.
- Don't forget to copy the shadowed state over on duplicate.

I wish we could do better, but I think that's the best we can achieve without 
removing the hack.

I want/need to rework the core property handling, and this hack is
getting in the way. But since it's a non-standard propety only used by
legacy userspace we know that this will only every be called from
ioctl code. And never on some other free-standing state struct, where
this old hack wouldn't work either.

v2: don't forget zorder and get_property!

v3: Shadow the legacy state to avoid locking issues in get_property
(Maarten).

v4: Review from Laurent
- Move struct omap_crtc_state into omap_crtc.c
- Clean up comments.
- Don't forget to copy the shadowed state over on duplicate.

v5: Don't forget to update the reset handler (Maarten).

With atomic we should try to always make the getprop values accurate, or compositors might have
troubles restoring.

I would update the shadow values in omap_crtc_atomic_check through omap_crtc_atomic_check instead,
with something like this:

+       pri_state = drm_atomic_get_new_plane_state(crtc->primary, state->state);
+       if (pri_state) {
+               struct omap_crtc_state *omap_crtc_state =
+                       to_omap_crtc_state(state);
+
+               omap_crtc_state->zpos = pri_state->zpos;
+               omap_crtc_state->rotation = pri_state->rotation;
+       }

That way even when updating the property through the primary plane, it gets reflected correctly. For example when vt switching
with fbdev.

Hm, perhaps add a __drm_atomic_helper_crtc_reset, and (perhaps) for planes too?

Similar to __drm_atomic_helper_connector_reset, in case we want to add something in the future that might need to be initialised. :)

Let's not make it over-complicated. This hack is only needed fo the legacy X 
OMAP modesetting driver. The CRTC zpos and rotation properties should not be 
used through the atomic API.

Marten is right, the atomic properties are all such that you can
unconditionally restore them (e.g. fences report a no-op value), to
make compositor switching easier. Not sure anyone implements that, but
I think it's a useful idea to keep. I'll respin (or maybe Maarten
simply submits his patch with a proper sob ...).

Here you go, compile tested version. :)

I want/need to rework the core property handling, and this hack is
getting in the way. But since it's a non-standard propety only used by
legacy userspace we know that this will only every be called from
ioctl code. And never on some other free-standing state struct, where
this old hack wouldn't work either.

v2: don't forget zorder and get_property!

v3: Shadow the legacy state to avoid locking issues in get_property
(Maarten).

v4: Review from Laurent
- Move struct omap_crtc_state into omap_crtc.c
- Clean up comments.
- Don't forget to copy the shadowed state over on duplicate.

v5: Don't forget to update the reset handler (Maarten).
v6: Update omap_crtc_state shadow values in omap_crtc_atomic_check (Maarten).

This makes all the CRTC properties disappear...

This doesn't depend on anything in drm-next, does it? I'm currently on
v4.13-rc3. I'll look a bit more on what's going on later today.

Not that I know of. Later patches will, but this one should be stand-alone.

The properties should not disappear, does kms_properties pass?

Oh derp, I also see what's going wrong..

omap_crtc_atomic_get_property returns the value, instead of setting *val and returning 0.

Next version coming up!

I want/need to rework the core property handling, and this hack is
getting in the way. But since it's a non-standard propety only used by
legacy userspace we know that this will only every be called from
ioctl code. And never on some other free-standing state struct, where
this old hack wouldn't work either.

v2: don't forget zorder and get_property!

v3: Shadow the legacy state to avoid locking issues in get_property
(Maarten).

v4: Review from Laurent
- Move struct omap_crtc_state into omap_crtc.c
- Clean up comments.
- Don't forget to copy the shadowed state over on duplicate.

v5: Don't forget to update the reset handler (Maarten).
v6: Update omap_crtc_state shadow values in omap_crtc_atomic_check (Maarten).
v7:
- Fix get_property to return 0 and set value in *val (Maarten).
- Update comment in set_property for changes in v6 (Maarten).

[PATCH 2/8] drm: Don't update property values for atomic drivers

[Daniel Vetter]

Atomic drivers only use the property value store for immutable (i.e.
can't be set by userspace, but the kernel can still adjust it)
properties. The only tricky part is the removal of the update in
drm_atomic_helper_update_legacy_modeset_state().

This was added in

commit 8c10342cb48f3140d9abeadcfd2fa6625d447282 (tag: topic/drm-misc-2015-07-28)
Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Date:   Mon Jul 27 13:24:29 2015 +0200

    drm/atomic: Update legacy DPMS state during modesets, v3.

by copying it from the i915 code, where it was originally added in

commit 68d3472047a572936551f8ff0b6f4016c5a1fdef
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Thu Sep 6 22:08:35 2012 +0200

    drm/i915: update dpms property in set_mode

for the legacy modeset code. The reason we needed this hack was that
i915 didn't yet set DRIVER_ATOMIC, and we checked for that instead of
the newer-ish drm_drv_uses_atomic_modeset(), which avoids such
troubles. With the correct feature checks this isn't needed anymore at
all.

Also make sure that drivers don't accidentally get this wrong by
making the exported version of drm_object_property_get_value() only
work for legacy drivers. Only gma500 uses it anyway.

You've inverted the checks here for connector and crtc. :)

Otherwise looks sane, fix this and you can add my r-b.

On second thought, as penance you should add kms_properties to the fast-feedback testlist. ;)

[PATCH] drm: Don't update property values for atomic drivers

[Daniel Vetter]

Atomic drivers only use the property value store for immutable (i.e.
can't be set by userspace, but the kernel can still adjust it)
properties. The only tricky part is the removal of the update in
drm_atomic_helper_update_legacy_modeset_state().

This was added in

commit 8c10342cb48f3140d9abeadcfd2fa6625d447282 (tag: topic/drm-misc-2015-07-28)
Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Date:   Mon Jul 27 13:24:29 2015 +0200

    drm/atomic: Update legacy DPMS state during modesets, v3.

by copying it from the i915 code, where it was originally added in

commit 68d3472047a572936551f8ff0b6f4016c5a1fdef
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Thu Sep 6 22:08:35 2012 +0200

    drm/i915: update dpms property in set_mode

for the legacy modeset code. The reason we needed this hack was that
i915 didn't yet set DRIVER_ATOMIC, and we checked for that instead of
the newer-ish drm_drv_uses_atomic_modeset(), which avoids such
troubles. With the correct feature checks this isn't needed anymore at
all.

Also make sure that drivers don't accidentally get this wrong by
making the exported version of drm_object_property_get_value() only
work for legacy drivers. Only gma500 uses it anyway.

v2: Fixup the uses_atomic_modeset() checks (Maarten)

It would have been nice to remove the calls to drm_object_property_set_value() 
for the dpms property from drivers before adding this :-/ Three drivers (rcar-
du, shmobile and fsl-dcu) initialize the connector's DPMS property to OFF 
using this call (the default being ON).

Following the DPMS code paths always give me a headache, so if you know by 
heart how I should replace the set property call, I'm all ears :-)

Remove, it doesn't do anything for kms drivers. The value these calls
update was never consulted when reading the property, instead
drm_atomic_connector_get_property() directly looks at
drm_connector->dpms. These calls where only needed for legacy modeset.
Also note that the default _ON is the right one, since DPMS state is
in addition to modeset state. dpms should actually be set to _ON when
you enable the display using a modeset call, atomic takes care of that
in drm_atomic_helper_update_legacy_modeset_state().

Aka we found a using this WARN_ON!

And if you think the above explanation should be somewhere in
kerneldoc, pls add :-)

But DRM_IOCTL_MODE_OBJ_GETPROPERTIES doesn't, it gets the property value 
directly, doesn't it ?

Sure, but the connectors should start disabled, shouldn't they ?

It redirects to the atomic machinery, so should all work out.

Sure, and they are, because connector_state->crtc == NULL. DPMS only
matters if your connector is connected, which at boot-up/reset state it
isnt. Yes DPMS is one of those thing which with hindsight I'd like to
never have happened, it's probably the most quirky uabi we have :-/ 

If you have userspace that gets confused by this we need to:
a) either fix your userspace
b) if we decide to fix the kernel, fix it for everyone (i.e. in
drm_connector_init).

Given that the "standard kms driver" (aka i915.ko) doesn't do that, I
don't think we need b).

[PATCH 3/8] drm: Handle properties in the core for atomic drivers

[Daniel Vetter]

The reason behind the original indirection through the helper
functions was to allow existing drivers to overwrite how they handle
properties. For example when a vendor-specific userspace had
expectations that didn't match atomic. That seemed likely, since
atomic is standardizing a _lot_ more of the behaviour of a kms driver.

But 20 drivers later there's no such need at all. Worse, this forces
all drivers to hook up the default behaviour, breaking userspace if
they forget to do that. And it forces us to export a bunch of core
function just for those helpers.

And finally, these helpers are the last places using
drm_atomic_legacy_backoff() and the implicit acquire_ctx.

This patch here just implements the new behaviour and updates the
docs. Follow-up patches will garbage-collect all the dead code.

v2: Fixup docs even better!

v3: Make it actually work ...

[PATCH] drm: Handle properties in the core for atomic drivers

[Daniel Vetter]

The reason behind the original indirection through the helper
functions was to allow existing drivers to overwrite how they handle
properties. For example when a vendor-specific userspace had
expectations that didn't match atomic. That seemed likely, since
atomic is standardizing a _lot_ more of the behaviour of a kms driver.

But 20 drivers later there's no such need at all. Worse, this forces
all drivers to hook up the default behaviour, breaking userspace if
they forget to do that. And it forces us to export a bunch of core
function just for those helpers.

And finally, these helpers are the last places using
drm_atomic_legacy_backoff() and the implicit acquire_ctx.

This patch here just implements the new behaviour and updates the
docs. Follow-up patches will garbage-collect all the dead code.

v2: Fixup docs even better!

v3: Make it actually work ...

v4: Drop the uses_atomic_modeset() checks from the previous patch
again, since they're now moved up in the callchain.

[PATCH 5/8] drm: Nuke drm_atomic_helper_plane_set_property

[Daniel Vetter]

It's dead code, the core handles all this directly now. This also
allows us to unexport drm_atomic_helper_plane_set_property.

[PATCH 5/8] drm: Nuke drm_atomic_helper_plane_set_property

[Daniel Vetter]

It's dead code, the core handles all this directly now. This also
allows us to unexport drm_atomic_helper_plane_set_property.

[PATCH 5/8] drm: Nuke drm_atomic_helper_plane_set_property

[Daniel Vetter]

It's dead code, the core handles all this directly now. This also
allows us to unexport drm_atomic_helper_plane_set_property.

Hi Daniel,

Thank you for the patch.

I assume you meant drm_atomic_plane_set_property. With that fixed,

[PATCH 6/8] drm: Nuke drm_atomic_helper_connector_set_property

[Daniel Vetter]

It's dead code, the core handles all this directly now. This also
allows us to unexport drm_atomic_helper_connector_set_property.

The only special case is nouveau which used one function for both
pre-nv50 legacy modeset code and post-nv50 atomic world instead of 2
vtables. But amounts to exactly the same.

What is rather strange here is how few drivers set this up, I suspect
the earlier patch to handle properties in the core did end up fixing a
pile of possible issues.

Legacy drivers didn't always hook it up either, probably why. :)
No use hooking it up in legacy world if you didn't expose a property.

But yeah, good to fix this.

[PATCH 7/8] drm: Nuke drm_atomic_helper_connector_dpms

[Daniel Vetter]

It's dead code, the core handles all this directly now.

The only special case is nouveau and tda988x which used one function
for both legacy modeset code and -nv50 atomic world instead of 2
vtables. But amounts to exactly the same.

v2: Rebase over the panel/brideg refactorings in stm/ltdc.

[PATCH 7/8] drm: Nuke drm_atomic_helper_connector_dpms

[Daniel Vetter]

It's dead code, the core handles all this directly now.

The only special case is nouveau and tda988x which used one function
for both legacy modeset code and -nv50 atomic world instead of 2
vtables. But amounts to exactly the same.

v2: Rebase over the panel/brideg refactorings in stm/ltdc.

You're missing one patch here. We should also mark dev->mode_config.acquire_ctx __private. That way atomic commits will never be able to use lock_all. :)

Though I think it requires fixing vmwgfx_fb.c and i915 first.

Otherwise series looks good, so with review comments addressed.
