H A Delf_hwcaps.rst11 ARM64 ELF hwcaps
14 這篇文檔描述了 arm64 ELF hwcaps 的用法和語義。
22 公開一組稱爲 hwcaps 的標誌而把這些功能暴露給用戶空間。
29 unsigned long hwcaps = getauxval(AT_HWCAP);
30 if (hwcaps & HWCAP_FP)
46 大多數 hwcaps 旨在說明通過架構 ID 寄存器(處於 EL0 的用戶空間代碼無法訪問)
50 這些 hwcaps 以下面的形式描述::
54 當 idreg.field 中有 val 時，hwcaps 表示 ARM ARM 定義的功能是有效的，但是
57 其他 hwcaps 可能表明無法僅由 ID 寄存器描述的功能的存在。這些 hwcaps 可能
