Delf_hwcaps.rst8 ARM64 ELF hwcaps
11 这篇文档描述了 arm64 ELF hwcaps 的用法和语义。
19 公开一组称为 hwcaps 的标志而把这些功能暴露给用户空间。
26 unsigned long hwcaps = getauxval(AT_HWCAP);
27 if (hwcaps & HWCAP_FP)
43 大多数 hwcaps 旨在说明通过架构 ID 寄存器(处于 EL0 的用户空间代码无法访问)
47 这些 hwcaps 以下面的形式描述::
51 当 idreg.field 中有 val 时，hwcaps 表示 ARM ARM 定义的功能是有效的，但是
54 其他 hwcaps 可能表明无法仅由 ID 寄存器描述的功能的存在。这些 hwcaps 可能

Delf_hwcaps.rst4 ARM64 ELF hwcaps
7 This document describes the usage and semantics of the arm64 ELF hwcaps.

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