1 2 TEST SUITE: 3 4 The directory cpuset contains the tests related to the cpuset controller. 5 6 Cpuset is a mechanism for assigning a set of CPUs and Memory Nodes to a set of 7 tasks. 8 9 There are total 258 testcases that have been added till date. Now, These 10 testcases contain the basis operation test and part functionality test of 11 cpuset, such as: adding/removing cpus/mems, setting flags, exclusive function, 12 hierarchy relation, inherit relation, cpuset VS syscall and so on 13 14 NOTE: the test can be run by root only. And 4 CPUs and 3 Memory Nodes is need 15 to run it at least. 16 17 TESTS AIM: 18 19 The aim of the tests is to test the functionality of cpuset. 20 21 FILES DESCRIPTION: 22 23 cpuset_base_ops_test 24 -------------------- 25 Directory containing the shell script which is used to test the basis 26 operation of cpuset. such as: adding/removing cpus/mems, setting flags. 27 28 cpuset_exclusive_test 29 --------------------- 30 Directory containing the shell script which is used to test exclusive 31 function of cpuset. 32 33 cpuset_hierarchy_test 34 --------------------- 35 Directory containing the shell script is used to test hierarchy relation 36 of cpuset. 37 38 cpuset_syscall_test 39 ------------------- 40 Directory containing the shell script and program which are used to test 41 syscalls whether they collide with cpuset. 42 43 cpuset_hotplug_test 44 ------------------- 45 Directory containing the shell script and program which are used to test 46 cpu hotplug whether they collide with cpuset. 47 48 cpuset_load_balance_test 49 ------------------------ 50 Directory containing the shell script and program which are used to test 51 scheduler domains partitions. Beside that, they are also used to check that 52 whether load balance breaks the cpuset's limit. 53 54 cpuset_memory_pressure_test 55 --------------------------- 56 Directory containing the shell script and program which are used to test 57 memory pressure measurement function. 58 59 cpuset_memory_spread_test 60 ------------------------- 61 Directory containing the shell script and program which are used to test 62 page caches spread. There are two control files. One is memory_spread_page which 63 is used to control the allocation of page caches, the other is 64 memory_spread_slab which is used to control the allocation of slab objects. 65 Because there are much factor to affect the result of slab spread test, it 66 is hard to test it. So we just test memory_spread_page. 67 68 cpuset_memory_test 69 ------------------ 70 Directory containing the shell script and program which are used to test 71 memory allocation. 72 73 cpuset_lib 74 ---------- 75 This directory contains the library and script for cpuset controller testing. 76 such as: cpuset_funcs.sh(functions for cpuset test script) 77 78 run_cpuset_test.sh 79 ------------------ 80 This script runs all the 190 testcases. 81 82 Makefile 83 -------- 84 Each directory in cpuset has its usual makefile, it is for its directory. 85 86 README 87 ------ 88 The one you have gone through. 89 90
