2018-01-18alloc-stress: add test to generate memory pressure from multiple processesSuren Baghdasaryan
multichild-stress test spawns user-specified number of child processes which allocate blocks of memory generating memory pressure on the device and potentially causing lmk kills. Typical usage: multichild-stress -i10 -s10000 -d100 -o500 -g This generates 10 children each allocating 10000 bytes every 100ms, oom_score of each child is 500 and each will have its own memory cgroup. This test is mainly for testing lmkd performance. Bug: 63631020 Change-Id: Ia1071ccc10924a7bae3735d3e5acde6fad195ca3 Signed-off-by: Suren Baghdasaryan <surenb@google.com>

2017-08-25Memory pressureSherry Yang
Create continuous memory pressure by adjusting a child process's oom score and allocate in the child. When a child is killed by the low-memory-killer, fork another process and continues until the program is killed or certain number of iterations has reached.

2016-01-18Fix up alloc-stress.Martijn Coenen
- Userspace now uses ranges -1000 to +1000 for oomadj - Directly call into lmkd instead of writing oom_score-adj; this allows alloc-stress to work with userspace lmkd - If mem cgroups are enabled (future), create a mem cgroup for the newly created process.
