From: Isaku Yamahata <isaku.yamahata@xxxxxxxxx> This patch series is to implement test cases for the KVM gmem error_remove_page method. - Update punch hole method to truncate pages - Add a new ioctl KVM_GUEST_MEMORY_FAILURE to inject memory failure on offset of gmem TODO: - Update TDX KVM to handle it and Add test cases for TDX. This will be done by its own patch series. Changes: v2: - rebased to [RFC PATCH v12 00/33] KVM: guest_memfd() and per-page attributes https://lore.kernel.org/all/20230914015531.1419405-1-seanjc@xxxxxxxxxx/ - introduce new ioctl to inject memory fault on gmem and drop FIBMAP hack - Implement test cases v1: https://lore.kernel.org/all/cover.1694599703.git.isaku.yamahata@xxxxxxxxx/ Isaku Yamahata (6): KVM: gmem: Truncate pages on punch hole KVM: selftests: Add negative test cases for punch hole for guest_memfd() KVM: selftests: Add tests for punch hole on guest_memfd KVM: gmem: Add ioctl to inject memory failure on guest memfd KVM: selftests: Add test cases for KVM_GUEST_MEMORY_FAILURE KVM: guest_memfd: selftest: Add test case for error_remove_page method include/uapi/linux/kvm.h | 6 + tools/testing/selftests/kvm/Makefile | 1 + .../testing/selftests/kvm/guest_memfd_test.c | 80 ++++ .../kvm/x86_64/private_mem_conversions_test.c | 26 +- .../kvm/x86_64/private_mem_hwpoison_test.c | 367 ++++++++++++++++++ virt/kvm/guest_mem.c | 82 +++- 6 files changed, 554 insertions(+), 8 deletions(-) create mode 100644 tools/testing/selftests/kvm/x86_64/private_mem_hwpoison_test.c base-commit: 42dc814987c1feb6410904e58cfd4c36c4146150 prerequisite-patch-id: 3c646922da088ceebe447974a90217f377b76e4a prerequisite-patch-id: 635c4dca26af8d105a4fd8f603e4a9cf830395c7 prerequisite-patch-id: eede5382aa76c0602a853fc93a1450995c651345 prerequisite-patch-id: 5549aad02248eb5a0c2853058dc7c102044c7a9d prerequisite-patch-id: ab6557f79edb77246ee1e9955be81a10841e65fd prerequisite-patch-id: bf75388851ee37a83b37bfa7cb0084f27301f6bc prerequisite-patch-id: cecffe9a2445f2ea01b9fdb1356b1c87eb6b8fe7 prerequisite-patch-id: e1692d657690f974d836ba3efdd277ea82e675ca prerequisite-patch-id: 747debe72334ef0cd12bbb42d1acb281eb59cd98 prerequisite-patch-id: 2d1df1bad8af51577ec15a37510ea8bf018b0d4f prerequisite-patch-id: d05f7429ca893fe0fe3beb460bba1400379cd0d1 prerequisite-patch-id: 9916b6553a61beb9a5435bc0b1fcacf0a87165ea prerequisite-patch-id: 313219882d617e4d4cb226760d1f071f52b3f882 prerequisite-patch-id: 5412c4037793bc0999377f9732290b9944257b7c prerequisite-patch-id: b737a534d8da531f6d030be5e864a3097ca97384 prerequisite-patch-id: cafe1f6964532d261b950e1879e091dc8c0b4386 prerequisite-patch-id: 20a5d5b1f853828061ccb07ed08459b9922e5214 prerequisite-patch-id: 756402fa0914a86ac7db59aa54e36a7bca9d0770 prerequisite-patch-id: 0e93d19cb59f3a052a377a56ff0a4399046818aa prerequisite-patch-id: 8576bf7ec9f786870e72b78299dcab5dd4eb0d23 prerequisite-patch-id: 0693f3aa65226ff9ffa1f70b6f6da2410ebd0588 prerequisite-patch-id: 301dbdf8448175ea609664c890a3694750ecf740 prerequisite-patch-id: 8f67d4366ca5c9875c4ef7f445941e3ad3162c75 prerequisite-patch-id: 2d62d84b4f9db4148af35495ce1b188c6b46f421 prerequisite-patch-id: b4526dee5b5a95da0a13116ae0c73d4e69efa3c6 prerequisite-patch-id: 8a2b4167ea632413ba8f6d39788ddf19eb928ab0 prerequisite-patch-id: 5618d2414a1ef641b4c247b5e28076f67a765b24 prerequisite-patch-id: 4415e2df6492fbb64746e3503deba6e991a0e08b prerequisite-patch-id: ba50138fe73e9a5f58e19eebaab2c17a2dc231e3 prerequisite-patch-id: 1225df90aeae430a74354bc5ad0ddf508d0707db prerequisite-patch-id: 4c0e6ab89b9a3ed3a2cb236e942b5842926bf868 prerequisite-patch-id: 59f78d417ca58088e336f8e2a9540d1c95bd2f6c prerequisite-patch-id: b6a6a8916fe89e7da1fadefb7d311960732e0faf -- 2.25.1
