5 This document describes the usage and semantics of the arm64 ELF hwcaps.
15 of flags called hwcaps, exposed in the auxilliary vector.
23 unsigned long hwcaps = getauxval(AT_HWCAP);

40 2. Interpretation of hwcaps
43 The majority of hwcaps are intended to indicate the presence of features
45 userspace code at EL0. These hwcaps are defined in terms of ID register
49 Such hwcaps are described below in the form::
53 Such hwcaps indicate the availability of functionality that the ARM ARM
