Support external display rendering in vr flinger Add support for external displays to vr flinger, hidden behind a system property until we're ready to use it. To turn it on for testing: $ adb shell setprop persist.vr.use_external_display 1 With external display support turned on and an external display connected, all output is redirected to the external display, and we switch to the external display's vsync. Bug: 75047963 Test: Most of the testing was done on a Polaris, which now supports external display hotplugging. - Tested external display connect/disconnect while the device was donned. - Tested external display connect/disconnect while doffed. - Verified booting with the external display connected doesn't cause the device to crash, although we don't seem to get a hotplug event for the external display until the cable is disconnected and reconnected, so we output to the primary display at first. - Did some basic testing on a Walleye to confirm vr behavior there is unchanged. - Verified the external display is ignored when the sysprop is unset.

SF: Separate Hwc2::Composer into interface and impl This makes the android::Hwc2::Composer substitutable. In this case the intent is to allow a mock::Composer GMock class to be defined. Hwc2::Composer now is a pure interface class. Hwc2::impl::Composer is the normal implementation. Also included is another minor change to allow HWC2::Device to be constructed with a Hwc2::Composer (interface) pointer instead of a service name. This means that now SurfaceFlinger itself constructs the Hwc2::impl::Composer using the service name, rather than passing it down a call chain. Test: Code builds Bug: None Change-Id: Ic79f645cee40c534651b9c7b70f05497d98e51dc

Fix race condition when enabling vr flinger The following sequence could result in the surface flinger main thread getting blocked indefinitely: 1. A vr flinger client creates a surface to be displayed. 2. Vr flinger requests the display from surface flinger. 3. The surface flinger main thread calls mVrFlinger->GrantDisplayOwnership(), to give the display to vr flinger. The main thread blocks in HardwareComposer::Enable(), as it waits for the vr flinger post thread to start running. 4. The vr flinger client from step 1 destroys or hides its display surface. 5. The post thread, signaled by the main thread in step 3, wakes up, but since it has no surfaces to draw, it goes back to sleep. At this point the surface flinger main thread will be stuck indefinitely, as it waits for the post thread to start running. Since the post thread has no work to do it'll never start running. Waiting for the post thread to change state is only necessary when surface flinger takes the display back from vr flinger, in which case we need to wait for the post thread to destroy its connection to hardware composer before continuing. I added separate code to wait for the post thread in that case, and removed the code to wait in the other cases. Bug: 72335362 Test: It's pretty hard to hit the timing to expose the race condition. I locally modified the code to add a sleep in HardwareComposer::Enable(), after asking the post thread to resume but before checking to see if it's resumed, and quickly exited vr during the sleep (on a phone). I confirmed the surface flinger main thread became stuck waiting for the post thread to resume. Since the code to wait for the post thread is removed in this CL, the race condition is fixed. I also tested normal vr usage on phones and standalones. Change-Id: I75c26be91cf0dd1c910de5443c80cfd18ca629b7 (cherry picked from commit b0ea58eca378cb09a81e3afd9d23d2090d2ba8c3)

Remove spurious composer validate call to avoid hang Presumably during Doff transitions as the hardware composer post thread was being interrupted, there was an edge case when a validate command could be posted without following up with present. That could lead to create/delete layer calls between validate and present which are not supported by some HWC implementations. Bug: 70178957 Test: manually verified that create layer will fail if done between validate and present.

Have vr flinger take the display after boot on standalones 1. Have vr flinger request the display immediately after boot finishes on standalones, to prevent incorrectly showing normal 2d content from surface flinger on the display during startup. 2. If we don't get any surfaces to show for a while after boot finishes, turn the display off. This should only occur if VrCore is misbehaving somehow. Bug: 65742855 Test: - Verified no flickering in the boot anim. - Verified that if no surfaces are created the display is turned off. Change-Id: Ibfcd97101334e552d1d562fe4ae9c36877b44397

Fix usage of HWC_DISPLAY_PRIMARY in vr flinger The hardware composer functions require display ids obtained from the onHotplug() composer callback. Our vr flinger code was supplying HWC_DISPLAY_PRIMARY as the primary display id, which is incorrect. The HWC_DISPLAY_* values are used for representing the display type, not the display id. The code worked anyway because most hardware composers always use 0 as the primary display id, which happens to be the same value as HWC_DISPLAY_PRIMARY. The emulator uses 1 as the primary display id though, which exposed the bug. This CL changes the vr flinger code to get the display id from the onHotplug() composer callback, and uses that value when talking to hardware composer, instead of HWC_DISPLAY_PRIMARY. This matches the behavior of surface flinger. Bug: 69631196 Test: Verified the vr flinger code path works as expected on phones and standalones. Change-Id: Ia691941d0eafaa1f89e0ee81a4ae27fdef5a57cf

Minor cleanup to DvrConfig processing in vrflinger The intention of the previous code was to update the sequence number so that the struct was only updated on new config changes. The sequence number needs to be incremented to achieve that behavior. This is minor, because the previous code is harmless: it just sets the 16 byte struct every time through, which isn't much different from the new code. Bug: 66969271 Test: confirmed with VrCore change to set the DvrConfig struct. Change-Id: Ica60e2dc8b7d852d56549bab574a6802cea592fc (cherry picked from commit 4fa590c446e8103a6642e95e382ef8c7d9d1aa8e)

Use the HWC caching mechanism to avoid stalls in the ion driver. HWC supports caching buffers for layers using "slot" assignments. Use this in VrFlinger to avoid importing a buffer handle every frame. The avoids periodic stalls we observe in the ion driver when mapping a buffer into the HWC address space.

Deal with unreliable VSYNC signals due to scheduler. We see two sources of scheduler jank when waiting for VSYNC: - A kernfs issue that wakes up threads using a normal priority work queue that may be delayed or have other work on it. - The VSYNC callback from HWC is handled by a normal priority HwBinder thread that may be delayed by other work. Change the VrFlinger frame post thread to use an absolute timer- based dead reckoning loop. VSYNC timestamps from the display driver are reliable, even if the delivery of the value takes time. Predict the VSYNC time into the future based on the last known VSYNC time. If we see that VSYNC has not been signaled by the time we need to post a frame to HWC we assume that the driver and/or HWC was delayed so much that the previous frame is still pending and skip the upcoming frame to avoid double stuffing the driver. Bug: 65064949 Test: Extensive system tests and systraces. See bug for details. Change-Id: Iae6c4173b8eac1d179adc3fc8004d3d475b3f156

Use a separate hwcomposer hidl instance for vr flinger Improve robustness of vr flinger <--> surface flinger switching by having vr flinger use a separate hardware composer hidl instance instead of sharing the instance with surface flinger. Sharing the hardware composer instance has proven to be error prone, with situations where both the vr flinger thread and surface flinger main thread would write to the composer at the same time, causing hard to diagnose crashes (b/62925812). Instead of sharing the hardware composer instance, when switching to vr flinger we now delete the existing instance, create a new instance directed to the vr hardware composer shim, and vr flinger creates its own composer instance connected to the real hardware composer. By creating a separate composer instance for vr flinger, crashes like the ones found in b/62925812 are no longer impossible. Most of the changes in this commit are related to enabling surface flinger to delete HWComposer instances cleanly. In particular: - Previously the hardware composer callbacks (which come in on a hwbinder thread) would land in HWC2::Device and bubble up to the SurfaceFlinger object. But with the new behavior the HWC2::Device might be dead or in the process of being destroyed, so instead we have SurfaceFlinger receive the composer callbacks directly, and forward them to HWComposer and HWC2::Device. We include a composer id field in the callbacks so surface flinger can ignore stale callbacks from dead composer instances. - Object ownership for HWC2::Display and HWC2::Layer was shared by passing around shared_ptrs to these objects. This was problematic because they referenced and used the HWC2::Device, which can now be destroyed when switching to vr flinger. Simplify the ownership model by having HWC2::Device own (via unique_ptr<>) instances of HWC2::Display, which owns (again via unique_ptr<>) instances of HWC2::Layer. In cases where we previously passed std::shared_ptr<> to HWC2::Display or HWC2::Layer, instead pass non-owning HWC2::Display* and HWC2::Layer* pointers. This ensures clean composer instance teardown with no stale references to the deleted HWC2::Device. - When the hardware composer instance is destroyed and the HWC2::Layers are removed, notify the android::Layer via a callback, so it can remove the HWC2::Layer from its internal table of hardware composer layers. This removes the burden to explicitly clear out all hardware composer layers when switching to vr flinger, which has been a source of bugs. - We were missing an mStateLock lock in SurfaceFlinger::setVsyncEnabled(), which was necessary to ensure we were setting vsync on the correct hardware composer instance. Once that lock was added, surface flinger would sometimes deadlock when transitioning to vr flinger, because the surface flinger main thread would acquire mStateLock and then EventControlThread::mMutex, whereas the event control thread would acquire the locks in the opposite order. The changes in EventControlThread.cpp are to ensure it doesn't hold a lock on EventControlThread::mMutex while calling setVsyncEnabled(), to avoid the deadlock. I found that without a composer callback registered in vr flinger the vsync_event file wasn't getting vsync timestamps written, so vr flinger would get stuck in an infinite loop trying to parse a vsync timestamp. Since we need to have a callback anyway I changed the code in hardware_composer.cpp to get the vsync timestamp from the callback, as surface flinger does. I confirmed the timestamps are the same with either method, and this lets us remove some extra code for extracting the vsync timestamp that (probably) wasn't compatible with all devices we want to run on anyway. I also added a timeout to the vysnc wait so we'll see an error message in the log if we fail to wait for vsync, instead of looping forever. Bug: 62925812 Test: - Confirmed surface flinger <--> vr flinger switching is robust by switching devices on and off hundreds of times and observing no hardware composer related issues, surface flinger crashes, or hardware composer service crashes. - Confirmed 2d in vr works as before by going through the OOBE flow on a standalone. This also exercises virtual display creation and usage through surface flinger. - Added logs to confirm perfect layer/display cleanup when destroying hardware composer instances. - Tested normal 2d phone usage to confirm basic layer create/destroy functionality works as before. - Monitored surface flinger file descriptor usage across dozens of surface flinger <--> vr flinger transitions and observed no file descriptor leaks. - Confirmed the HWC1 code path still compiles. - Ran the surface flinger tests and confirmed there are no new test failures. - Ran the hardware composer hidl in passthrough mode on a Marlin and confirmed it works. - Ran CTS tests for virtual displays and confirmed they all pass. - Tested Android Auto and confirmed basic graphics functionality still works.

Fix vr flinger post thread to resume correctly After being paused, the vr flinger post thread remained paused until it was enabled by requesting display ownership, but the request for display ownership was made from the vr flinger post thread, causing the post thread to get stuck in the paused state forever. I moved the display ownership request to the vr flinger dispatcher thread, so the post thread can be resumed. Bug: 62666511 Test: Put a device through a sleep/wake cycle and confirmed the vr flinger post thread resumes as expected. Change-Id: Ic57adb7376c8f2b5760bfaa4a5a30b58894a7ab7

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. Change-Id: I15abfde5f72dbb3725a3f58621486afba6b64902

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. Change-Id: I85832b87f393754dc6b034eb38f2937d7b58ed74

Fix BlockUntilVSync() to actually block 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. Change-Id: Iec4951e014575a5d0ed3cfe3fc20ea91c67edf1b

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.

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.
