_create _lock failure causes b2g process to crash
+++ This bug was initially created as a clone of Bug #862097 +++
Bug 862097 is reported as abort in content process. Though it is actually caused by a crash in b2g process. When a gralloc buffer allocation in b2g process is failed by genlock_create_lock failure, b2g process crash.

Stack trace looks very much like the bug was fixed by https://www.codeaurora.org/gitweb/quic/b2g/?p=build.git;a=commitdiff;h=cee98d7cbfd59c1c4b4379c4b094aebc0d601c82 I suggest retesting with this patch applied!

Thanks, it works! It needs to update the related source. v1.01 and v1-train do not use recent source. need to update.
Ugh, that's unfortunate. Moz builds really need to track the vendor tree more closely, especially for v1.0.1 and v1-train. Happy to discuss my POV on this tomorrow if anybody cares (oh prolly not ;) )
Yeah, I also think so. I did not know about it until yesterday.
This bug itself does not affect our partners, but it can affect our testing on unagi devices. Given that, we're not treating this as a blocker. To fix this ourselves we just need a set of patches applied to our unagi builds, and mwu will provide the list of said patches.

From https://www.codeaurora.org/gitweb/quic/lf/?p=build.git;a=summary , we'll need: patch/all/hardware/qcom/display/remap-copybit-formats.patch patch/ics/system/vold/Remove-g-rx-from-sdcard.patch patch/ics_strawberry/external/bluetooth/bluez/0001-Remove-OPP-L2cap-SDP-record.patch patch/ics_strawberry/frameworks/base/OMXCodec-stop-now-waits-for-all-buffers-to-return.patch patch/ics_strawberry/frameworks/base/surfaceflinger_remove_layer_alpha.patch patch/ics_strawberry/hardware/libhardware/hwc_header_remove_layer_alpha.patch patch/ics_strawberry/hardware/msm7k/OMX_Deinit-symbol-fix.patch patch/ics_strawberry/hardware/qcom/display/display-add-fillcolor.patch patch/ics_strawberry/hardware/qcom/display/gpu-free-when-alloc-fails.patch patch/ics_strawberry/hardware/qcom/display/hwc_impl_remove_layer_alpha.patch patch/ics_strawberry/hardware/qcom/display/no-rgb565-dither.patch patch/ics_strawberry/hardware/qcom/display/preserve-framebuffer-contents-on-initialization.patch patch/ics_strawberry/hardware/qcom/media/OMX_Deinit-symbol-fix.patch patch/ics_strawberry/kernel/kernel-add-fillcolor.patch For hamachi, use the v1 branch. For leo, use the v1.1 branch. Unagi requires a separate set of patches but it probably won't be worth it to attempt fixing things there.
Can we add: patch/ics_strawberry/system/core/Revert-msm7627a-Change-adj-level-and-min_free_kbytes.patch
gonk-patches@master: ca1113b The bluez patch from comment 10 wasn't included in hamachi for some reason so I added it in this patch.
Patching infrastructure is up and patching the important things.

mwu, are there a new kernel(boot.img) for moz build that applying the above kernel patch?
After the bug was fixed, I ceated a v1.0.1 buri's ROM by enabling HwComposer. I see following problem. Is it related to kernel? - During playing a wideo video on Bug 850566, I rotate an orientation of the device, drawing at previous orientation appeared in black background drawing. - During scrolling in a web content like following, drawing often flashed by white color. https://blog.mozilla.org/sumo/2013/03/09/content-tuning/
We still can't enable HWC. There's a patch we need on the gecko side that hasn't landed yet.

Bug 832383. The patch posted there isn't the latest, however. You'll want something like https://www.codeaurora.org/gitweb/quic/lf/?p=build.git;a=blob;f=patch/all/gecko/HWC-multirect-visible-region.patch;h=1e1f6bde3a648dceb9d3a7f8bff27054e2030936;hb=refs/heads/v1.1
Thanks for the info! By applying the patch the first problem in comment #15 is solved. But the second one is not solved.
