2251d822dac2a96aad4184a6fdc2690f0a58af7c 21-Apr-2017 Corey Tabaka <eieio@google.com> Remove the VR compositor from the framework.

Remove the VR compositor framework and enable out-of-process VR composition
in VrCore.

This CL seems large due to the ripple effect of changing the VrFlinger
API and protocol types. There are three major modules that require
concurrent changes:
1. Protocol definitions and low-level VrFlinger API in libdisplay.
* Additional changes needed to keep old interfaces working for
a short time while replacing the dependent code (dvrGraphics*).
2. VrFlinger service implementation changes to support VrCore compositor
and the removal of the internal compositor.
3. Changes to libdvr platform library API due to changes in #1 and #2.

Because of the nature of the interdependence of types and other defs it is
difficult to break this CL into smaller chunks. However, review of the three
major modules (libdisplay, libdvr, and libvrflinger) may be done separately
to ease the mental burden on reviewers.

Change Summary:
- Remove obsolete screenshot service. VR screenshots will be implemented
by VrCore.
- Update display protocol definitions for changes in VrFlinger service
requirements. The majority of the changes in libdisplay are a
consequence of these protocol and service changes.
- Update VrFlinger to support two kinds of surfaces:
1. Application - use by VR apps.
2. Direct - used by VrCore (protected by permission check).
- Remove VrFlinger internal compositor and GL context.
- Remove obsolete debug console.
- Update VrFlinger hardware composer interface to handle direct
surfaces only, removing the concept of GPU (compositor) layers.
- Update display manager to expose access to application surface info
to VrCore (protected by permission check).
- Update libdvr platform library interfaces for changes to VrFlinger
API / protocol.
- Clean up libdvr API struct setup using a common include.
- Add C++ header-only helpers for DVR platform library opaque types.

Bug: 36401174
Test: Build; run VrFlinger display test tool.

0af4b9f88a48a6ecc705b4a8cec3d3ba24c53ead 26-Apr-2017 Steven Thomas <steventhomas@google.com> Call validateDisplay() when skipping frames

Layer management was getting screwed up in vr flinger in the following
scenario:

1. In frame X, post a new buffer to layer L.

2. Decide to skip frame X (e.g. because we're behind our target
schedule).

3. In frame X+1, delete layer L.

When we skip the frame in step 2, we weren't calling validateDisplay()
or presentDisplay() on the hardware composer, so the composer's internal
command queue wasn't being flushed. When we called validateDisplay() for
frame X+1 the update buffer call from frame X would be run, referencing
the deleted layer L, causing a crash.

Now we always call validateDisplay() when we change the layer state,
even if we decide to skip the frame.

I also added code to explicitly clear the Composer object's internal
command buffer when we transfer control from surface flinger to vr
flinger and back. There were certain cases where there could be commands
left in the command buffer after the display handoff.

Bug: 37159844

Test: I used an app switcher script that quickly switches vr apps, which
would consistently trigger the setLayerBuffer crash. I confirmed with
this CL applied I can run the app switcher until surface flinger runs
out of file descriptors (that's a separate bug), and I never see the
setLayerBuffer crash. I also confirmed from the log output there are no
additional hardware composer errors.

In my refactoring in ag/2008740 I introduced a regression where blocking
until the next vsync would busy loop instead of actually blocking on an
event on the vsync fd. The problem was I changed the poll() call to
listen for POLLIN in addition to POLLPRI. While waiting for vsync events
we only want to listen for POLLPRI.

Bug: 36495351

Test: Confirmed with debug logs the busy loop bug and that we correctly
block with this patch applied.

050b2c83304bd16ec3a838da08b6ba6acf6a3af4 06-Mar-2017 Steven Thomas <steventhomas@google.com> Revert "Revert "Tie vr flinger to persistent vr mode""

This reverts commit 7480c060cb3466d97ec3125d61bbace153f534c8.

Transfer display control to vr flinger when persistent vr mode is
entered, rather than when vr mode is entered. This allows cardboard
apps, which will invoke vr mode but not persistent vr mode, to work as
in N.

This activates vr flinger at device boot for Daydream ready devices,
which fixes an issue where an app would attempt to create a surface
before vr flinger was running, which would hang indefinitely.

The VrManager listener for persistent vr mode is put in vr flinger
instead of surface flinger. This is cleaner since the vr interaction
with the rest of the device is now consolidated in vr flinger.

While testing I encountered a problem where vr flinger was given control
of the display but vsync was turned off, causing vr flinger's post
thread to hang. I changed the vr flinger logic to give control over
vsync and other display settings to the post thread, and took the
opportunity to further simplify and improve vr flinger's thread
interactions.

Bug: 35885165

Test: Manually confirmed that when persistent vr mode is not invoked we
get the N-based render implementation, and when persistent vr mode is
invoked we get vr flinger.

282a5ed48f64e4010f97ca4077e3bd4b54ba3268 08-Feb-2017 Steven Thomas <steventhomas@google.com> Fix vr flinger deadlock and race condition

While investigating hangs when transitioning from 2d --> vr and back I
found a deadlock and race condition in the vr flinger pause/resume
handling. This CL should fix both issues.

Unfortunately there's still another deadlock related to multiple threads
trying to suspend/resume vr flinger, but considering how vr flinger is
currently used by surface flinger we shouldn't ever hit that scenario in
practice.

Bug: None

Test: I was able to reliably get a hang when starting/stopping vr
launcher a few times, but with this CL applied and another CL to remove
calls to SetPowerMode() applied (that CL will be submitted separately),
I no longer see any hangs.
