b4cc4430 - drivers: base: Add basic devm tests for platform devices

drivers: base: Add basic devm tests for platform devicesPlatform devices show some inconsistencies with how devm resources arereleased when the device has been probed and when it hasn't.In particular, we can register device-managed actions no matter if thedevice has be bound to a driver or not, but devres_release_all() willonly be called if it was bound to a driver or if there's no referenceheld to it anymore.If it wasn't bound to a driver and we still have a reference,devres_release_all() will never get called. This is surprisingconsidering that if the driver isn't bound but doesn't have anyreference to it anymore, that function will get called, and if it wasbound to a driver but still has references, that function will getcalled as well.Even if that case is fairly unusual, it can easily lead to memory leaks.The plan is, with the next patch, to make it consistent and enforce thatdevres_release_all() is called no matter what situation we're in. Fornow, it just tests for the current behaviour and skips over theinconsistencies.Reviewed-by: David Gow Signed-off-by: Maxime Ripard Link: https://lore.kernel.org/r/20230720-kunit-devm-inconsistencies-test-v3-2-6aa7e074f373@kernel.orgSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/base/test/Makefile

06188bc8 - drivers: base: Add basic devm tests for root devices

Thu, 20 Jul 2023 12:45:07 +0000

drivers: base: Add basic devm tests for root devicesThe root devices show some odd behaviours compared to regular "bus" devicesthat have been probed through the usual mechanism, so let's create kunittests to exercise those paths and odd cases.It's not clear whether root devices are even allowed to use devicemanaged resources, but the fact that it works in some cases but notothers like shown in that test suite shouldn't happen either way: wewant to make it consistent and documented.These tests will (after the following patches) ensure that consistencyand effectively document that it's allowed.If it ever turns out to be a bad idea, we can always roll back andmodify the tests then.Reviewed-by: David Gow Signed-off-by: Maxime Ripard Link: https://lore.kernel.org/r/20230720-kunit-devm-inconsistencies-test-v3-1-6aa7e074f373@kernel.orgSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/base/test/Makefile

aa811e3c - software node: introduce CONFIG_KUNIT_DRIVER_PE_TEST

Tue, 14 Jan 2020 16:09:43 +0000

software node: introduce CONFIG_KUNIT_DRIVER_PE_TESTCurrently the property entry kunit tests are built if CONFIG_KUNIT=y.This will cause warnings when merged with the kunit tree that nowsupports tristate CONFIG_KUNIT. While the tests appear to compileas a module, we get a warning about missing module license.It's better to have a per-test suite CONFIG variable so thatwe can do selective building of kunit-based suites, and canalso avoid merge issues like this.Fixes: c032ace71c29 ("software node: add basic tests for property entries")Reported-by: Stephen Rothwell Reported-by: Randy Dunlap Signed-off-by: Alan Maguire Signed-off-by: Rafael J.

79543cf2 - driver-core: add test module for asynchronous probing

Thu, 29 Sep 2016 15:13:14 +0000

driver-core: add test module for asynchronous probingThis test module tries to test asynchronous driver probing by having adriver that sleeps for an extended period of time (5 secs) in itsprobe() method. It measures the time needed to register this driver(with device already registered) and a new device (with driver alreadyregistered). The module will fail to load if the time spent in registercall is more than half the probing sleep time.As a sanity check the driver will then try to synchronously registerdriver and device and fail if registration takes less than half of theprobing sleep time.Signed-off-by: Dmitry Torokhov Reviewed-by: Olof Johansson Signed-off-by: Guenter Roeck Signed-off-by: Thierry Escande Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/base/test/Makefile
