Bug Description

Mir servers crash with SIGSEGV in libhybris-common.so.1 on Nexus7, when using android's hw composer.

gdb ./mir_demo_server_basic

This might be the same issue crashing integration-tests.... ?

old nexus 7 (nvidia hardware) or new nexus 7 (qcom hardware)?

it might be that the hwc isn't working for the nexus 7. You can try to mv /system/lib/hw/hwcomposer.* out of that directory, which will force mir into a backup composition mode.

Thanks for the suggestion, Kevin. Unfortunately this doesn't seem to help. :(

I did a quick check, and noticed that it crashes in my_pthread_mutex_lock, a hybris hook for the original pthread_mutex_lock.

The problem is that the mutex used (__mutex) contains an anddress that's not part of the mapped memory region for the process, causing a segfault when we try to access the content of such variable.

To make things even more complicated, the call is originated by /system/lib/hw/gralloc.tegra3.so, and if you also refuse to handle the lock, it'll crash inside the library later on.

Seems to be related with the hwcomposer, as after removing /system/lib/hw/hwcomposer.tegra3.so I'm able to start mir_demo and run a few examples.

Unity8 is crashing still it seems, still debugging.

Ok, the other unity8 related crash was because we didn't had the permissions set right. Will be pushing a change to lxc-android-config to get that fixed.

Also uploading a new android package without the hwcomposer for grouper, until we're able to ignore it from Mir itself (could use getprop to check if grouper, and not load it).

Hopefully tomorrow we should have an image which is capable of running Mir. There's still one rendering issue when opening apps and moving back to the shell, but will report that properly once the image is out.

Ricardo Salveti (rsalveti) wrote :

After a bit of more investigation, this actually seems to be a bug in the way Mir is using the hwcomposer interface (not using the 2 layers, and also with a different init/flags set).

The crash happens because it tries to use a pthread_mutex that is not initialized. From our current investigation nothing is calling/using this pthread_mutex before the crash, so it's probably due a different code path used with Mir.

Kevin DuBois (kdub) wrote :

the issue was that the hwcomposer was relying on HWC_GEOMETRY_CHANGED flag to do some initialization of its internal data structures (including some pthread mutexes). Mir was not setting this flag leaving those mutexes uninitialized. When hwc tried to lock the uninitialized mutexes, we would segfault in hybris at that point.

Fixed by
1) setting HWC_GEOMETRY_CHANGED during posting
2) submitting a skipped gles layer to force posting everytime.

for the reports about 'my nexus 7 works'....

In mir, we first try to load the HWC display mechanism, and then, if we can't load HWC, we load an alternative display mechanism (FB)

We saw that the HWC was segfaulting, so we removed hwcomposer.tegra3.so from the build. This forced FB composition.
After the fix lands, we can safely add back hwcomposer.tegra3.so to the build.

This bug was fixed in the package mir - 0.1.2+14.04.20131128.1-0ubuntu1

---------------
mir (0.1.2+14.04.20131128.1-0ubuntu1) trusty; urgency=low

  [ Kevin Gunn ]
  * New upstream release 0.1.2
    - graphics: android: improve interface for mga::DisplayDevice so its
      just concerned with rendering and posting.
    - surfaces: rename "surfaces" component to "scene".
    - surfaces, shell: Migrate Session data model from shell to surfaces.
    - graphics: change fill_ipc_package() to use real pointers.
    - mir_client_library.h: Fix typo "do and locking" should be "do any
      locking".
    - API enumerations cleanup: Remove slightly misleading *_enum_max_
      values, and replace them with more accurate plural forms.
    - test_android_communication_package: Do not expect opened fd to be >0,
      we may have closed stdin making this a valid value (LP: #1247718).
    - Update docs about running Mir on the desktop to mention new package
      ubuntu-desktop-mir.
    - offscreen: Add a display that renders its output to offscreen buffers
    - graphics: android: fix regression for hwc1.0 devices introduced in r1228
      (LP: #1252433).
    - OffscreenPlatform provides the services that the offscreen display
      needs from the Platform.
    - graphics: android: consolidate the GLContexts classes in use.
    - Fix uninitialized variable causing random drm_auth_magic test
      failures. (LP: #1252144).
    - Add a fullyish functional Udev wrapper. This currently sits in
      graphics/gbm, but will be moved to the top-level when input device
      detection migrates.
    - Add resizing support to example code; demo-shell and clients.
    - eglapp: Clarify messages about pixel formats (LP: #1168304).
    - Adds support to the MirMotionEvent under pointer_coordinates called
      tool_type. This will allow clients to tell what type of tool is
      being used, from mouse/finger/etc. (LP: #1252498)
    - client,frontend: Report the real available surface pixel formats to
      clients. (LP: #1240833)
    - graphics: android: 1) change hwc1.1 to make use of sync fences during
      the compositor's gl renderloop. Note that we no longer wait for the
      render to complete, we pass this responsibility to the driver and the
      kernel. 2) support nexus 10. (LP: #1252173) (LP: #1203268)
    - shell: don't publish SurfacesContainer - it can be private to shell.
    - gbm: Don't mess up the VT mode on setup failure Only restore the
      previous VT mode during shutdown if it was VT_AUTO.
    - Fix a crash due to a failed eglMakeCurrent() call when in nested mode.
    - shell: unity-mir uses shell::FocusSetter - make the header public again
    - Add resize support to client surfaces (mir::client::MirSurface).
    - graphics: android: support 'old aka 2012' nexus 7 hwc (nvidia tegra3
      SoC) better. (LP: #1231917)
    - Add resize support to *ClientBuffer classes. Now always get dimensions
      from the latest buffer package.
    - android: support driver hooks for the Mali T604 (present in nexus 10)
    - Add width and height to the protocol Buffer messages, in preparation
      for resizable surfaces.
    - surfaces, shell, logging, te...
