+=====================
+ARM64中的 HugeTLBpage
+=====================
+
+大页依靠有效利用 TLBs 来提高地址翻译的性能。这取决于以下
+两点 -
+
+ - 大页的大小
+ - TLBs 支持的条目大小
+
+ARM64 接口支持2种大页方式。
+
+1) pud/pmd 级别的块映射
+-----------------------
+
+这是常规大页,他们的 pmd 或 pud 页面表条目指向一个内存块。
+不管 TLB 中支持的条目大小如何,块映射可以减少翻译大页地址
+所需遍历的页表深度。
+
+2) 使用连续位
+-------------
+
+架构中转换页表条目(D4.5.3, ARM DDI 0487C.a)中提供一个连续
+位告诉 MMU 这个条目是一个连续条目集的一员,它可以被缓存在单
+个 TLB 条目中。
+
+在 Linux 中连续位用来增加 pmd 和 pte(最后一级)级别映射的大
+小。受支持的连续页表条目数量因页面大小和页表级别而异。
+
+
+支持以下大页尺寸配置 -
