| H A D | kern_mib.c | diff 259465 Mon Dec 16 13:02:49 MST 2013 nwhitehorn MFC r258819,258928: Add new sysctl, kern.supported_archs, containing the list of FreeBSD MACHINE_ARCH values whose binaries this kernel can run. This patch provides a feature requested for implementing pkgng ABI identifiers in a robust way. The list is designed to indicate whether, say, an i386 package can be run on the current system. If kern.supported_abis contains "i386", then the answer is yes. Otherwise, the answer is no. At the moment, this only supports MACHINE_ARCH and MACHINE_ARCH32. As we gain support for more interesting combinations, this needs to become more flexible, possibily through the sysent framework, along with the hw.machine_arch emulation immediately preceding this code in kern_mib.c.
