Allocate pages in NUMA nodes A and B. * 2. Use move_pages() to retrieve the NUMA node of the pages. * 3. Check if the NUMA nodes reported are correct. * * USAGE: <for command-line> * move_pages01 [-c n] [-i n] [-I x] [-P x] [-t] * where, -c n : Run n copies concurrently. * -i n : Execute test n times. * -I x : Execute test for x seconds. * -P x : Pause for x seconds between iterations. * -t : Turn on syscall timing. * * History * 05/2008 Vijay Kumar * Initial Version. * * Restrictions * None */ #include <sys/signal.h> #include <sys/types.h> #include <sys/wait.h> #include <errno.h> #include "test.h" #include "move_pages_support.h" #define TEST_PAGES 2 #define TEST_NODES TEST_PAGES void setup(void); void cleanup(void); char *TCID = "move_pages01"; int TST_TOTAL = 1; int main(int argc, char **argv) { tst_parse_opts(argc, argv, NULL, NULL); setup(); #ifdef HAVE_NUMA_V2 int lc; /* check for looping state if -i option is given */ for (lc = 0; TEST_LOOPING(lc); lc++) { void *pages[TEST_PAGES] = { 0 }; int status[TEST_PAGES]; int ret; /* reset tst_count in case we are looping */ tst_count = 0; ret = alloc_pages_linear(pages, TEST_PAGES); if (ret == -1) continue; ret = numa_move_pages(0, TEST_PAGES, pages, NULL, status, 0); if (ret != 0) { tst_resm(TFAIL|TERRNO, "move_pages failed"); free_pages(pages, TEST_PAGES); continue; } verify_pages_linear(pages, status, TEST_PAGES); free_pages(pages, TEST_PAGES); } #else tst_resm(TCONF, "test requires libnuma >= 2 and it's development packages"); #endif cleanup(); tst_exit(); } /* * setup() - performs all ONE TIME setup for this test */ void setup(void) { tst_sig(NOFORK, DEF_HANDLER, cleanup); check_config(TEST_NODES); /* Pause if that option was specified * TEST_PAUSE contains the code to fork the test with the -c option. */ TEST_PAUSE; } /* * cleanup() - performs all ONE TIME cleanup for this test */ void cleanup(void) { }
