Hi, After SAP discontinued the support of linuxppc64 and aixppc64 of OpenJDK 8 I want to share how we ran the hotspot jtreg tests, and especially which tests we excluded. Most of the test excludes could be fixed by downporting test changes. Also, issues might be fixed after we excluded them, I did not check this. We build with only mandatory configure settings, except for the following: linuxppc64: --with-extra-cflags=-Wno-strict-aliasing aix: --with-native-debug-symbols=internal We run jtreg with the following settings: -Djava.awt.headless=true -k:(!headful)&(!ignore)&(!stress)&(!intermittent) We excluded the following tests: First, tests that fail on all platforms we tested: # Testbug # This test copied or moved the root directory / to some subdirectory, filling up the disc compiler/ciReplay/TestSA.sh generic-all compiler/ciReplay/TestVM_no_comp_level.sh generic-all compiler/ciReplay/TestVM.sh generic-all # Fails in 8 until 8044416 will be fixed or # the test exclusion change 8044540 will be downported from jdk9 serviceability/sa/jmap-hashcode/Test8028623.java generic-all # Fixed in 11 by 8195621: JTReg failure: gc/g1/TestLargePageUseForAuxMemory.java gc/g1/TestLargePageUseForAuxMemory.java generic-all Further, tests we see failing on ppc but not on x86_64. # Class data sharing not implemented on ppc. runtime/CDSCompressedKPtrs/CDSCompressedKPtrs.java generic-ppc64 runtime/CDSCompressedKPtrs/CDSCompressedKPtrsError.java generic-ppc64 runtime/CompressedOops/CompressedClassPointers.java generic-ppc64 runtime/NMT/NMTWithCDS.java generic-ppc64 runtime/NMT/VirtualAllocCommitUncommitRecommit.java generic-ppc64 runtime/SharedArchiveFile/CdsDifferentObjectAlignment.java generic-ppc64 runtime/SharedArchiveFile/CdsSameObjectAlignment.java generic-ppc64 runtime/SharedArchiveFile/LimitSharedSizes.java generic-ppc64 runtime/SharedArchiveFile/PrintSharedArchiveAndExit.java generic-ppc64 runtime/SharedArchiveFile/SharedArchiveFile.java generic-ppc64 runtime/SharedArchiveFile/SharedBaseAddress.java aix-ppc64 runtime/SharedArchiveFile/SpaceUtilizationCheck.java generic-ppc64 # C1 not implemented.
