logcat of few bootanimation cycles
Hi,
I'm testing Android 8.1 (oreo-x86 branch of android-x86)
with the following gfx stack:
- drm_hwcomposer of freedesktop.org (hwctwo enabled and also with robherring
branch handle-rework)
- latest gbm_gralloc (robherring branch handle-rework, but also happening with
branches prior to handle-rework)
- latest libdrm, but it happens will all releases from 2.4.89(and before) to
2.4.91
- latest kernel 4.17rc4, but it happens with all kernels
Hardware: Laptop Lenovo T460 with Skylake GT2
Synthomps: Bootanimation completes, but then the Android GUI hangs and
surfaceflinger service is killed, Bootanimations restarts (GUI bootloop)
Very difficult to get debug logs, about what is causing signal 1 (SIGHUP)
killing surfaceflinger, but I could finally trace it.
05-07 21:36:58.689 0 0 I : [drm] GPU HANG: ecode
9:0:0x00280000, in surfaceflinger [2497], reason: No progress on rcs0, action:
reset
05-07 21:36:58.689 0 0 I : [drm] GPU hangs can indicate a bug
anywhere in the entire gfx stack, including userspace.
05-07 21:36:58.689 0 0 I : [drm] Please file a _new_ bug report
on bugs.freedesktop.org against DRI -> DRM/Intel
05-07 21:36:58.689 0 0 I : [drm] drm/i915 developers can then
reassign to the right component if it's not a kernel issue.
05-07 21:36:58.689 0 0 I : [drm] The gpu crash dump is required
to analyze gpu hangs, so please always attach it.
05-07 21:36:58.689 0 0 I : [drm] GPU crash dump saved to
/sys/class/drm/card0/error
05-07 21:36:58.689 0 0 I i915 0000: 00:02.0: Resetting rcs0 after gpu
hang
logcat, dmesg and GPU crash dump /sys/class/drm/card0/error are provided.
Please help to identify the root cause as this is probably the only show
stopper preventing drm_hwcomposer (hwctwo) + gbm_gralloc + libdrm from booting
Android oreo-x86 with full freedesktop stack.
I am available to support further investigations and testing of patches
