首先将4.4.45 转为16进制为 0x04.0x04.0x2D 然后宏 KERNEL_VERSION(0x04,0x04,0x2D)展开之后得到04042D 这个16进制的数字 最后将0x040423 转化为十进制就得到了十进制的263213 即为 LINUX_VERSION_CODE的值263213 可以利用下面的代码根据linux内核版本号的不同调用不同的API函数: #ifLINUX_VERSION_CODE < KE...
This is the physical memory directly accessible by the kernel and is related to the kernel/userspace split in the linear address space marked by PAGE OFFSET. 我理解为这段地址kernel可以直接访问,可以通过PAGE_OFFSET宏直接将kernel所用的虚拟地址转换成物理地址的区段。在文件mm/bootmem.c中对这个变量...
所以他的可用内存是434884KB,已用内存是3489800KB,第三行所指的是从应用程序角度来看,对于应用程序来说,buffers/cached 是等于可用的,因为buffer/cached是为了提高文件读取的性能,当应用程序需在用到内存的时候,buffer/cached会很快地被回收。

linux 内核 LINUX_VERSION_CODE 和 KERNEL_VERSION 宏定义 版本信息_linux driver linux_version_cod-CSDN博客 由于Linux版本的在不断更新,当设备驱动去兼容不同版本的内核时,需要知道当前使用的内核源码版本,以此来调用对应版本的内核API,这两个宏定义在文件 /usr/include/linux/version.h #define LINUX_VERSION_COD...
kernel_addr >> 4 + CONFIG_KASAN_SHADOW_OFFSET = kernel_addr对应的shadow_addr 四、sw_tag生成和验证流程分析 4.1 设置sw_tag 还是用kmalloc为例: kmalloc -->kmalloc_trace -->__kmem_cache_alloc_node -->slab_alloc_node -->slab_post_alloc_hook ...
