device property: build kunit tests without structleak plugin

2021-10-06T23:53:42Z

The structleak plugin causes the stack frame size to grow immensely when used with KUnit: ../drivers/base/test/property-entry-test.c:492:1: warning: the frame size of 2832 bytes is larger than 2048 bytes [-Wframe-larger-than=] ../drivers/base/test/property-entry-test.c:322:1: warning: the frame size of 2080 bytes is larger than 2048 bytes [-Wframe-larger-than=] ../drivers/base/test/property-entry-test.c:250:1: warning: the frame size of 4976 bytes is larger than 2048 bytes [-Wframe-larger-than=] ../drivers/base/test/property-entry-test.c:115:1: warning: the frame size of 3280 bytes is larger than 2048 bytes [-Wframe-larger-than=] Turn it off in this file.

device property: Remove some casts in property-entry-test

2021-06-23T22:37:21Z

With some of the stricter type checking in KUnit's EXPECT macros removed, several casts in property-entry-test are no longer required. Remove the unnecessary casts, making the conditions clearer.

software node: Introduce SOFTWARE_NODE_REFERENCE() helper macro

2021-04-05T11:18:22Z

This is useful to assign software node reference with arguments in a common way. Moreover, we have already couple of users that may be converted. And by the fact, one of them is moved right here to use the helper.

device property: Add test cases for fwnode_property_count_*() APIs

Add test cases for fwnode_property_count_*() APIs. While at it, modify the arrays of integers to be size of non-power-of-2 for better test coverage and decreasing stack usage.

drivers: base: default KUNIT_* fragments to KUNIT_ALL_TESTS

2020-06-01T20:24:25Z

This makes it easier to enable all KUnit fragments. Adding 'if !KUNIT_ALL_TESTS' so individual tests can not be turned off. Therefore if KUNIT_ALL_TESTS is enabled that will hide the prompt in menuconfig. Reviewed-by: David Gow Signed-off-by: Anders Roxell Signed-off-by: Shuah Khan

software node: introduce CONFIG_KUNIT_DRIVER_PE_TEST

2020-01-16T23:23:37Z

Currently the property entry kunit tests are built if CONFIG_KUNIT=y. This will cause warnings when merged with the kunit tree that now supports tristate CONFIG_KUNIT. While the tests appear to compile as a module, we get a warning about missing module license. It's better to have a per-test suite CONFIG variable so that we can do selective building of kunit-based suites, and can also avoid merge issues like this.
