Subject: [PATCH v3 linux-kselftest-test 0/6] kunit: support building core/tests as modules
Date: Thu, 17 Oct 2019 19:07:13 +0100 [thread overview]
Message-ID: <1571335639-21675-1-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 4.
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. KUNIT_INIT_*SYMBOL() is defined so that a mismatch between
local symbol definition and definition of symbol in target will trigger
a compilation error when the object is compiled built-in (Brendan)
(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)
- fixed whitespace issues in doc (patch 6)
