This series adds basic self tests for HMM and are intended for Jason Gunthorpe's rdma tree which has a number of HMM patches applied. Changes v7 -> v8: Rebased to Jason's rdma/hmm tree, plus Jason's 6 patch series "Small hmm_range_fault() cleanups". Applied a number of changes from Jason's comments. Changes v6 -> v7: Rebased to linux-5.6.0-rc6 Reverted back to just using mmu_interval_notifier_insert() and making this series only introduce HMM self tests. Changes v5 -> v6: Rebased to linux-5.5.0-rc6 Refactored mmu interval notifier patches Converted nouveau to use the new mmu interval notifier API Changes v4 -> v5: Added mmu interval notifier insert/remove/update callable from the invalidate() callback Updated HMM tests to use the new core interval notifier API Changes v1 -> v4: https://lore.kernel.org/linux-mm/20191104222141.5173-1-rcampbell@xxxxxxxxxx Ralph Campbell (3): mm/hmm/test: add selftest driver for HMM mm/hmm/test: add selftests for HMM MAINTAINERS: add HMM selftests MAINTAINERS | 3 + include/uapi/linux/test_hmm.h | 59 ++ lib/Kconfig.debug | 12 + lib/Makefile | 1 + lib/test_hmm.c | 1177 +++++++++++++++++++++ tools/testing/selftests/vm/.gitignore | 1 + tools/testing/selftests/vm/Makefile | 3 + tools/testing/selftests/vm/config | 2 + tools/testing/selftests/vm/hmm-tests.c | 1353 ++++++++++++++++++++++++ tools/testing/selftests/vm/run_vmtests | 16 + tools/testing/selftests/vm/test_hmm.sh | 97 ++ 11 files changed, 2724 insertions(+) create mode 100644 include/uapi/linux/test_hmm.h create mode 100644 lib/test_hmm.c create mode 100644 tools/testing/selftests/vm/hmm-tests.c create mode 100755 tools/testing/selftests/vm/test_hmm.sh -- 2.20.1
