43fbd8cd - KVM: selftests: Provide empty 'all' and 'clean' targets for unsupported ARCHs

Thu, 28 Nov 2024 00:55:45 +0000

KVM: selftests: Provide empty 'all' and 'clean' targets for unsupported ARCHsProvide empty targets for KVM selftests if the target architecture isunsupported to make it obvious which architectures are supported, and sothat various side effects don't fail and/or do weird things, e.g. as is,"mkdir -p $(sort $(dir $(TEST_GEN_PROGS)))" fails due to a missing operand,and conversely, "$(shell mkdir -p $(sort $(OUTPUT)/$(ARCH_DIR) ..." willcreate an empty, useless directory for the unsupported architecture.Move the guts of the Makefile to Makefile.kvm so that it's easier to seethat the if-statement effectively guards all of KVM selftests.Reported-by: Muhammad Usama Anjum Acked-by: Muhammad Usama Anjum Acked-by: Andrew Jones Link: https://lore.kernel.org/r/20241128005547.4077116-15-seanjc@google.comSigned-off-by: Sean Christopherson List of files: /linux-6.15/tools/testing/selftests/kvm/.gitignore

9d15171f - KVM: selftests: Explicitly include committed one-off assets in .gitignore

Wed, 28 Aug 2024 21:58:00 +0000

KVM: selftests: Explicitly include committed one-off assets in .gitignoreAdd KVM selftests' one-off assets, e.g. the Makefile, to the .gitignore sothat they are explicitly included. The justification for omitting theone-offs was that including them wouldn't help prevent mistakes: Deliberately do not include the one-off assets, e.g. config, settings, .gitignore itself, etc as Git doesn't ignore files that are already in the repository. Adding the one-off assets won't prevent mistakes where developers forget to --force add files that don't match the "allowed".Turns out that's not the case, as W=1 will generate warnings, and theamazing-as-always kernel test bot reports new warnings: tools/testing/selftests/kvm/.gitignore: warning: ignored by one of the .gitignore files tools/testing/selftests/kvm/Makefile: warning: ignored by one of the .gitignore files>> tools/testing/selftests/kvm/Makefile.kvm: warning: ignored by one of the .gitignore files tools/testing/selftests/kvm/config: warning: ignored by one of the .gitignore files tools/testing/selftests/kvm/settings: warning: ignored by one of the .gitignore filesFixes: 43e96957e8b8 ("KVM: selftests: Use pattern matching in .gitignore")Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202408211818.85zIkDEK-lkp@intel.comLink: https://lore.kernel.org/r/20240828215800.737042-1-seanjc@google.comSigned-off-by: Sean Christopherson List of files: /linux-6.15/tools/testing/selftests/kvm/.gitignore

43e96957 - KVM: selftests: Use pattern matching in .gitignore

Tue, 13 Dec 2022 00:16:43 +0000

KVM: selftests: Use pattern matching in .gitignoreUse pattern matching to exclude everything except .c, .h, .S, and .shfiles from Git. Manually adding every test target has an absurdmaintenance cost, is comically error prone, and leads to bikesheddingover whether or not the targets should be listed in alphabetical order.Deliberately do not include the one-off assets, e.g. config, settings,.gitignore itself, etc as Git doesn't ignore files that are already inthe repository.

KVM: selftests: Hyper-V PV TLB flush selftestIntroduce a selftest for Hyper-V PV TLB flush hypercalls(HvFlushVirtualAddressSpace/HvFlushVirtualAddressSpaceEx,HvFlushVirtualAddressList/HvFlushVirtualAddressListEx).The test creates one 'sender' vCPU and two 'worker' vCPU which do busyloop reading from a certain GVA checking the observed value. SendervCPU swaos the data page with another page filled with a different value.The expectation for workers is also altered. Without TLB flush on workervCPUs, they may continue to observe old value. To guard against accidentalTLB flushes for worker vCPUs the test is repeated 100 times.Hyper-V TLB flush hypercalls are tested in both 'normal' and 'XMMfast' modes.Reviewed-by: Sean Christopherson Signed-off-by: Vitaly Kuznetsov Signed-off-by: Paolo Bonzini Message-Id: <20221101145426.251680-38-vkuznets@redhat.com>Signed-off-by: Paolo Bonzini List of files: /linux-6.15/tools/testing/selftests/kvm/.gitignore

Thememory in the data slot is filled with op-codes for the returninstruction. The guest then executes a series of accesses on the memory,some reads, some instruction fetches. After each operation, the guestexits and the test performs some checks on the backing page counts toensure that NX page splitting an reclaim work as expected.Reviewed-by: David Matlack Signed-off-by: Ben Gardon Message-Id: <20220613212523.3436117-7-bgardon@google.com>Signed-off-by: Paolo Bonzini List of files: /linux-6.15/tools/testing/selftests/kvm/.gitignore
