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
