system heap的 内存映射是在dma-buf 的ops中调用ion_heap_map_user 函数,此函数有个非常重要的参数struct vm_area_struct,它是进程虚拟内存管理的,其中有一些比较重要的变量,理解了这些变量的含义,理解下边的代码就非常简单了,首先看此结构体的定义,代码位于kernel\msm-4.14\include\linux\mm_types.h AI检测代码...

bitmap_find_next_zero_area_off: bitmap 中找到整块零区域 find_first_bit: bitmap 中找到第一个置位的位置 find_first_zero_bit: bitmap 中找到第一个清零的位置 find_last_bit: bitmap 中找到最后一个置位的位置 3.6.Bitmap 掩码操作 Bitmap 也提供了一套用于掩码的操作,和 bitops 的掩码相比...
位图(Bitmap)在 Linux 内核中使用非常广泛,比如用来标识中断是否已安装处理程序(used_vectors)、处理器是否在线(cpumask)等等。内核中,位图相关的接口及实现主要在以下几个文件中: include/linux/bitmap.h lib/bitmap.c lib/find_next_bit.c include/linux/bitops.h ...
