A new 'u_long *sv_hwcap' field is added to 'struct sysentvec'. A process ABI can set this field to point to a value holding a mask of architecture-specific CPU feature flags. If an ABI does not wish to supply AT_HWCAP to processes the field can be left as NULL. The support code for AT_EHDRFLAGS was already present on all systems, just the #define was not present. This is a step towards unifying the AT_* constants across platforms. Reviewed by: kib MFC after: 1 month Differential Revision: https://reviews.freebsd.org/D12290 |
