hi, I am seeing this error on my board when compilng core-image-x11 based image:
root@ifc6410:~# glxgears Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. [ 50.359341] Alignment trap: not handling instruction f4008a1f at [<b6cf3f84>] [ 50.364408] Unhandled fault: alignment exception (0x801) at 0x000cd5bc [ 50.371419] pgd = ec024000 [ 50.377885] [000cd5bc] *pgd=fb85f835 Bus error While I initially thought it was something to do with my kernel or firmware, I just thought about trying a build with GCCVERSION="4.9.3" and the issue is gone. I was having this issue as soon as EGL/GLES is being used, and I could get it with both X11 or Weston/Wayland. This is running on IFC6410 (e.g. an ARMv7 platform). The same images built for ARMv8 (DragonBoard 410c) work fine. I am using Mesa Gallium/freedreno for the GPU. I have tried armv7athf-neon and armv7at-neon, and both show the same issue. I would be curious to hear from others using similar platforms , though it is likely something in mesa/gallium (so possibly in freedreno bits).. Maybe someone using etnaviv ? Or is anyone building images for qemuarm v7? cheers nico
