This series takes another step along the path to atomic modeset / nuclear
pageflip by transitioning the i915 driver to the new atomic plane helpers
provided by Daniel Vetter in:
http://lists.freedesktop.org/archives/dri-devel/2014-November/071623.html
Previous work by Gustavo Padovan had already split most of the i915 plane
internals into separate prepare/check/commit steps, so a lot of the heavy
lifting was already done. This patch series sets up the hooks expected by the
atomic plane helpers, replaces the existing .update_plane() and
.disable_plane() entrypoints with the helpers, and does some general cleanup.
Patches #5 and #6 are the meat here; the other five patches are minor
refactoring and cleanup work.
I've tested this series on IVB with the plane-related i-g-t tests and some very
casual X usage.

We'll want to call this from the type-agnostic atomic plane helper
hooks. Since it's not sprite-specific anymore, more it to
intel_display.c as well.

A few of the sprite-related function names in i915 are very similar
(intel_plane_disable() vs intel_disable_plane() or
intel_enable_planes() vs intel_crtc_enable_planes()) and don't make it
clear whether they only operate on sprite planes, or whether they also
apply to all universal plane types. Rename a few functions to be more
consistent with our function naming for primary/cursor planes or to
clarify that they apply specifically to sprite planes:
- s/intel_disable_plane/intel_sprite_plane_disable/
- s/intel_disable_planes/intel_disable_sprite_planes/
- s/intel_enable_planes/intel_enable_sprite_planes/
Also, drop the sprite-specific intel_destroy_plane() and just use
the type-agnostic intel_plane_destroy() function. The extra 'disable'
call that intel_destroy_plane() did is unnecessary since the plane will
already be disabled due to framebuffer destruction by the point it gets
called.

Add the new driver entrypoints that will be called by the atomic plane
helpers.
This patch does not actually switch over to the new plane helpers yet,
so there should be no functional change here. Also note that although
plane programming was already split into check/prepare/commit steps,
some of the semantics of those individual functions will need to change
slightly when we do make the jump so that they match the behavior the
plane helpers expect.

To: intel-gfx; +Cc: dri-devel
Now that we have hooks to enable the atomic plane helpers, we can use
the plane helpers for our .update_plane() and .disable_plane()
entrypoints.
Even though we'd already refactored our plane handling code into
check/commit, we still have to rework some of that logic here as we make
the transition. The atomic plane helpers now call prepare_fb/cleanup_fb
for us, so note the following:
- 'commit' should not longer unpin the old object; the cleanup_fb will
take care of this for us
- prepare_fb only gets called when we actually have an fb, so the
internal 'disable' code needs to update frontbuffer tracking
- the cursor plane code never had 'prepare' code separated from its
'commit' function, so a lot of the cursor's 'commit' needs to be
dropped since prepare_fb already does it for us
- with all the pinning work removed from cursor commit, it can no
longer fail and should return void rather than int

7 siblings, 2 replies; 27+ messages in thread
From: Matt Roper @ 2014-11-13 18:43 UTC (permalink / raw)
To: intel-gfx; +Cc: dri-devel
The userspace-requested plane coordinates are now stored in
plane->state.base (and the i915-adjusted values are stored in
plane->state), so we no longer use the coordinate fields in intel_plane
or the orig_{src,dst} fields in intel_plane_state. Drop them.

Would it make sense to rename this to intel_sprite_plane_disable() as
part of this? It would be more consistent with the cursor and primary
plane naming conventions and likely avoid some confusion with the
intel_plane_disable() function.

Yeah, that happens in the next patch of the series (along with some
other naming cleanup). I tripped over the confusing names too many
times while working on this...

Hmm. Why do we even still have some kind of disable hook in the atomic
age? I would expect to just have .commit() or somesuch thing.
But is there's still some need for a disable hook, shouldn't we just call
the .disable_plane() hook of drm_plane? I guess I should really go and
read some this new helper stuff...

I don't think so. config vs new_config tracks pipe configuration during
the modeset sequence, but we're only doing a plane update here, so the
current crtc configuration is what we'd clip against. I haven't
converted over any of the CRTC modeset handling, just the plane updates.

You're right that it does eventually come down to
drm_plane_helper_commit() --> intel_plane_atomic_update() which should
be able to program the plane to either a new state or off. To reuse as
much of our existing code as possible and keep my changes minimal, I'm
just implementing intel_plane_atomic_update() as:
if (!plane->state->fb)
intel_plane_disable(plane);
else
intel_plane->commit_plane(plane, intel_state);
since we already had both of those functions implemented and working.
intel_plane->commit_plane() doesn't expect to be called in the disabled
case today (assumes crtc and/or fb are non-NULL), but it definitely
seems reasonable/easy to tweak that and roll the disable logic directly
into the lowest-level commit_plane in the future. I just wanted to keep
things as simple as possible with minimal code changes for the initial
patchset.

* [PATCH 5/8] drm/i915: Prepare for atomic plane helpers (v2)

Add the new driver entrypoints that will be called by the atomic plane
helpers.
This patch does not actually switch over to the new plane helpers yet,
so there should be no functional change here. Also note that although
plane programming was already split into check/prepare/commit steps,
some of the semantics of those individual functions will need to change
slightly when we do make the jump so that they match the behavior the
plane helpers expect.
v2:
- Renamed file from intel_atomic.c to intel_atomic_plane.c (Daniel)
- Fix a copy/paste comment mistake (Bob)

To: intel-gfx; +Cc: dri-devel
Now that we have hooks to enable the atomic plane helpers, we can use
the plane helpers for our .update_plane() and .disable_plane()
entrypoints.
Even though we'd already refactored our plane handling code into
check/commit, we still have to rework some of that logic here as we make
the transition. The atomic plane helpers now call prepare_fb/cleanup_fb
for us, so note the following:
- 'commit' should no longer unpin the old object; the cleanup_fb will
take care of this for us
- prepare_fb only gets called when we actually have an fb, so the
internal 'disable' code needs to update frontbuffer tracking
- the cursor plane code never had 'prepare' code separated from its
'commit' function, so a lot of the cursor's 'commit' needs to be
dropped since prepare_fb already does it for us
- with all the pinning work removed from cursor commit, it can no
longer fail and should return void rather than int
v2: Fix commit message typo (Bob)
Testcase: igt/kms_plane
Testcase: igt/kms_universal_plane
Testcase: igt/kms_cursor_crc

Actually, I don't think this is quite ready to go yet. I must have had
too much debug spam turned on before and missed the important messages
in the kernel log, but it looks like we're still calling something that
can sleep (in the frontbuffer tracking code?) while irqs are disabled
for vblank evasion.
I'll have to look into this some more tomorrow and decide what an
appropriate fix is.

Yeah the frontbuffer tracking code will sleep since it can grab mutexes.
We also want to eventually grow async support out of this, so I think the
best approach might be to simply use frontbuffer_flip_prepare/complete
around the entire sequence. Well the important part is that we call
prepare before we start waiting for outstanding rendering and complete
after pipe_update_end.
Since this loops over abstract plane objects I think we need to store the
correct frontbuffer tracking bit somewhere in intel_plane so that we can
get at them.

So I'm now wondering where all this code is disappearing into?
Anyway this conflicts pretty harshly with Gutavo's pending patches. I
think at least the particular patch touching this had the r-b already
(apart from a stale bo unre left behind, which can easily be fixed up
when applying the patch).
So I would like to get Gustavo's patches in first, especially as they
move the code already to the right direction. We also have bugs in the
current code that need to fixed. Gustavo's patches came close, but not
quite there IIRC. So I think it would be nice to get that stuff done
first, and then toss this atomic stuff on top.
