There're only > code stubs for other platform. I doubt this, since libcpuid.h mentions FreeBSD and Solaris support, and 'libcpuid/asm-bits.c' uses 'cpuid' whether it is Linux or Windows or not. Possibly there's more information available for Linux and Windows than for the hurd (see e.g. 'libcpuid/rdmsr.c'), but it would seem that _some_ usable information is available elsewhere. Also, 'libcpuid/rdmsr.c' uses 'modprobe', does this need to be absolutised? Greetings, Maxime.
