Hi all, I=E2=80=99ve just opened the following PR: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D206516 The patch, attached to the PR, basically suggests a way to obtain the = length of the list parsed by ofw_bus_parse_xref_list_alloc in advance = (e.g., without having to iterate until we get an error or a NULL = result). This would be useful in cases where we don=E2=80=99t know what = the length of the list would be, but we need to get all its parsed = entries and store a reference to them somewhere (e.g., a device=E2=80=99s = softc). This would be useful in particular for my Ralink/Mediatek MIPS work, = since there are, for example, chips in this family, that need to = enable/disable 2 clocks for USB and then there are others that only need = 1. The same goes for resets. Best wishes, Stanislav=
