smem reports physical memory usage, taking shared memory pages into account. Unshared memory is reported as the USS (Unique Set Size). Shared memory is divided evenly among the processes sharing that memory. The unshared memory (USS) plus a process's proportion of shared memory is reported as...
要分析memory leaks, 你需要知道总体的内存使用情况和划分. 以判断内存泄露是发生在user space, kernel space, mulit-media 等使用的memory, 从而进一步去判断具体的memory leaks. user space 使用的memory 即通常包括从进程直接申请的memory, 比如 malloc: 先mmap/sbrk 整体申请大块Memory 后再malloc 细分使用, 比如...
/* * It doesn't make any sense to retry for the compaction if the order-0 * reclaim is not able to make any progress because the current * implementation of the compaction depends on the sufficient amount * of free memory (see __compaction_suitable) */ //如果申请阶数大于0,判断是否需要...
memory usage in the system. When a process is killed, the shared libraries that contributed to its PSS will be proportionally distributed to the PSS totals for the remaining processes still using that library. In this way PSS can be slightly misleading, because when a process is killed, PSS ...
用户并没有运用咱们界说的DEBUG_NEW 宏,所以咱们无法在咱们的大局目标(appMemory)数据结构中找到对应的内存分配信息,可是由于它也没有运用DEBUG_DELETE,咱们为 delete 界说的两个大局 DELETE_FILE 和 DELETE_LINE 都不会有值,因而可以不打印 warning。 2. 用户的一个完结文件调用了 new 进行内存分配工作,可是该...
I need to get the memory usage of the current process in C. Can someone offer a code sample of how to do this on a Linux platform? I'm aware of the cat /proc/<your pid>/status method of getting memory usage, but I have no idea how to capture that in C. BTW, it's for a ...

关于ZONE_DEVICE, 具体的信息可以参见[ATCH v2 3/9 mm: ZONE_DEVICE for “device memory” While pmem is usable as a block device or via DAX mappings to userspace there are several usage scenarios that can not target pmem due to its lack of struct page coverage. In preparation for “hot pl...
