[Bug 1231917] Re: Mir servers crash with SIGSEGV in libhybris-common.so.1 on Nexus7 when using the hwcomposer (tegra3)
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. branch with fix is linked ** Changed in: mir Status: Confirmed = In Progress ** Branch linked: lp:~kdub/mir/n7-support -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1231917 Title: Mir servers crash with SIGSEGV in libhybris-common.so.1 on Nexus7 when using the hwcomposer (tegra3) To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1231917/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1231917] Re: Mir servers crash with SIGSEGV in libhybris-common.so.1 on Nexus7 when using the hwcomposer (tegra3)
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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1231917 Title: Mir servers crash with SIGSEGV in libhybris-common.so.1 on Nexus7 when using the hwcomposer (tegra3) To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1231917/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1231917] Re: Mir servers crash with SIGSEGV in libhybris-common.so.1 on Nexus7 when using the hwcomposer (tegra3)
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. ** Changed in: mir Status: Incomplete = Confirmed ** Changed in: mir Assignee: (unassigned) = Kevin DuBois (kdub) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1231917 Title: Mir servers crash with SIGSEGV in libhybris-common.so.1 on Nexus7 when using the hwcomposer (tegra3) To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1231917/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
