I think the kernel has problems with Android fences which were slowly
broken as they were de-staged:
1. They allowed for fence/timeline value/seqno to overflow/rollover and
that would break only if delta between timeline and earlier unsignaled
fence exceeded 2^31 or so. Android relies on that beha
Gustavo, you added fence_put()
in __drm_atomic_helper_plane_destroy_state(), shouldn't we also add a
corresponding fence_get() in __drm_atomic_helper_plane_duplicate_state() ?
