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...
Uss: This is the amount of memory that is committed to physical memory and is unique to a process; it is not shared with any other. It is the amount of memory that would be freed if the process were to terminate. USS is a useful metric for determining the actual memory usage of a ...
VSS(reported as VSZ from ps) is the total accessible address space of a process. This size also includes memory that may not be resident in RAM like mallocs that have been allocated but not written to. VSS is of very little use for determing real memory usage of a process. RSSis the ...
其触发点在linux-src/mm/page_alloc.c:__alloc_pages_may_oom,当使用各种方法都回收不到内存时会调用out_of_memory函数。 下面我们来看一下out_of_memory函数的实现(经过高度删减):linux-src/mm/oom_kill.c:out_of_memory bool out_of_memory(struct oom_control *oc) { select_bad_process(oc); oom_...
