The agent should 36 * set JVMTI_VERBOSE_GC with SetVerboseFlag. Check that outputs 37 * in stderr in both runs are equal. 38 * The test agent has a special input parameter 'setVerboseMode'. 39 * When VM runs the test class 'gf08t001' with 40 * '-agentlib:gf08t001=setVerboseMode=yes' 41 * option, then the agent calls SetVerboseFlag with 42 * JVMTI_VERBOSE_GC flag in Onload phase. 43 * The test's script wrapper runs the 'gf08t001' class twice. 44 * First time, with "setVerboseMode=yes" agent mode. Second 45 * time, with "setVerboseMode=no" agent mode and with 46 * "-verbose:gc" VM option. In both cases the output is 47 * searched for 'Full GC' string, unless ExplicitGCInvokesConcurrent 48 * is enabled and G1 is enbled. If ExplicitGCInvokesConcurrent and 49 * G1 is enbled the test searches for 'GC' string in output. 50 * The test fails if this string is not found in the output. 51 * COMMENTS 52 * 53 * @library /vmTestbase 54 * /test/lib 55 * @run driver jdk.test.lib.FileInstaller . . 56 * @build sun.hotspot.WhiteBox 57 * @run driver ClassFileInstaller sun.hotspot.WhiteBox 58 * sun.hotspot.WhiteBox$WhiteBoxPermission 59 * @run main/othervm/native 60 * -Xbootclasspath/a:. 61 * -XX:+UnlockDiagnosticVMOptions 62 * -XX:+WhiteBoxAPI 63 * TestDriver 64 */ 65 66 import sun.hotspot.code.Compiler; 67 68 public class TestDriver { 69 public static void main(String[] args) throws Exception { 70 sun.hotspot.WhiteBox wb = sun.hotspot.WhiteBox.getWhiteBox(); 71 Boolean isExplicitGCInvokesConcurrentOn = wb.getBooleanVMFlag("ExplicitGCInvokesConcurrent"); 72 Boolean isUseG1GCon = wb.getBooleanVMFlag("UseG1GC"); 73 Boolean isUseZGCon = wb.getBooleanVMFlag("UseZGC"); 74 Boolean isShenandoahGCon = wb.getBooleanVMFlag("UseShenandoahGC"); 75 Boolean isUseEpsilonGCon = wb.getBooleanVMFlag("UseEpsilonGC"); 76 77 if (Compiler.isGraalEnabled() && 78 (isUseZGCon || isUseEpsilonGCon || isShenandoahGCon)) { 79 return; // Graal does not support these GCs 80 } 81 82 String keyPhrase; 83 if ((isExplicitGCInvokesConcurrentOn && isUseG1GCon) || isUseZGCon || isShenandoahGCon) { 84 keyPhrase = "GC"; 85 } else { 86 keyPhrase = "Pause Full"; 87 } 88 89 nsk.jvmti.scenarios.general_functions.GF08.gf08t.main(new String[] { 90 "gf08t001", 91 nsk.jvmti.scenarios.general_functions.GF08.gf08t001.class.getName(), 92 keyPhrase, 93 "gc"}); 94 } 95 } 96
