Our memory management kernel CI testing at Red Hat uses the VM
selftests and we have run into two problems:
First, our LTP tests overlap with the VM selftests.
We want to avoid unhelpful redundancy in our testing practices.
Second, we have observed the current run_vmtests.sh to report overall
failure/ambiguous results in the case that a machine lacks the necessary
hardware to perform one or more of the tests. E.g. ksm tests that
require more than one numa node.
We want to be able to run the vm selftests suitable to particular hardware.
Add the ability to run one or more groups of vm tests via run_vmtests.sh
instead of simply all-or-none in order to solve these problems.
Preserve existing default behavior of running all tests when the script
is invoked with no arguments.
Documentation of test groups is included in the patch as follows:
# ./run_vmtests.sh [ -h || --help ]
usage: ./tools/testing/selftests/vm/run_vmtests.sh [ -h | -t "<categories>"]
-t: specify specific categories to tests to run
-h: display this message
The default behavior is to run all tests.
Alternatively, specific groups tests can be run by passing a string
to the -t argument containing one or more of the following categories
separated by spaces:
- mmap
tests for mmap(2)
- gup_test
tests for gup using gup_test interface
- userfaultfd
tests for userfaultfd(2)
- compaction
a test for the patch "Allow compaction of unevictable pages"
- mlock
tests for mlock(2)
- mremap
tests for mremap(2)
- hugevm
tests for very large virtual address space
- vmalloc
vmalloc smoke tests
- hmm
hmm smoke tests
- madv_populate
test memadvise(2) MADV_POPULATE_{READ,WRITE} options
- memfd_secret
test memfd_secret(2)
- process_mrelease
test process_mrelease(2)
- ksm
ksm tests that do not require >=2 NUMA nodes
- ksm_numa
ksm tests that require >=2 NUMA nodes
- pkey
memory protection key tests
- soft_dirty
test soft dirty page bit semantics
- anon_cow
test anonymous copy-on-write semantics
example: ./run_vmtests.sh -t "hmm mmap ksm"
