Subject: [PATCH v5 linux-kselftest-test 0/6] kunit: support building core/tests as modules
Date: Tue, 3 Dec 2019 12:07:42 +0000 [thread overview]
Message-ID: <1575374868-32601-1-git-send-email-alan.maguire@oracle.com> (raw)
The current kunit execution model is to provide base kunit functionality
and tests built-in to the kernel. The aim of this series is to allow
building kunit itself and tests as modules. This in turn allows a
simple form of selective execution; load the module you wish to test.
In doing so, kunit itself (if also built as a module) will be loaded as
an implicit dependency.
Because this requires a core API modification - if a module delivers
multiple suites, they must be declared with the kunit_test_suites()
macro - we're proposing this patch set as a candidate to be applied to the
test tree before too many kunit consumers appear. We attempt to deal
with existing consumers in patch 3.
Changes since v4:
- fixed signoff chain to use Co-developed-by: prior to Knut's signoff
(Stephen, all patches)
- added Reviewed-by, Tested-by for patches 1, 2, 4 and 6
- updated comment describing try-catch-impl.h (Stephen, patch 2)
- fixed MODULE_LICENSEs to be GPL v2 (Stephen, patches 3, 5)
- added __init to kunit_init() (Stephen, patch 5)
Changes since v3:
- removed symbol lookup patch for separate submission later
- removed use of sysctl_hung_task_timeout_seconds (patch 4, as discussed
with Brendan and Stephen)
- disabled build of string-stream-test when CONFIG_KUNIT_TEST=m; this
is to avoid having to deal with symbol lookup issues
- changed string-stream-impl.h back to string-stream.h (Brendan)
- added module build support to new list, ext4 tests
Changes since v2:
- moved string-stream.h header to lib/kunit/string-stream-impl.h (Brendan)
(patch 1)
- split out non-exported interfaces in try-catch-impl.h (Brendan)
(patch 2)
- added kunit_find_symbol() and KUNIT_INIT_SYMBOL to lookup non-exported
symbols (patches 3, 4)
- removed #ifdef MODULE around module licenses (Randy, Brendan, Andy)
(patch 4)
- replaced kunit_test_suite() with kunit_test_suites() rather than
supporting both (Brendan) (patch 4)
- lookup sysctl_hung_task_timeout_secs as kunit may be built as a module
and the symbol may not be available (patch 5)
Alan Maguire (6):
kunit: move string-stream.h to lib/kunit
kunit: hide unexported try-catch interface in try-catch-impl.h
kunit: allow kunit tests to be loaded as a module
kunit: remove timeout dependence on sysctl_hung_task_timeout_seconds
kunit: allow kunit to be loaded as a module
kunit: update documentation to describe module-based build
