cf996f03 - iio: test: test gain-time-scale helpers

Mon, 15 Jan 2024 14:26:07 +0000

iio: test: test gain-time-scale helpersSome light sensors can adjust both the HW-gain and integration time.There are cases where adjusting the integration time has similar impactto the scale of the reported values as gain setting has.IIO users do typically expect to handle scale by a single writable 'scale'entry. Driver should then adjust the gain/time accordingly.It however is difficult for a driver to know whether it should changegain or integration time to meet the requested scale. Usually it ispreferred to have longer integration time which usually improvesaccuracy, but there may be use-cases where long measurement times can bean issue. Thus it can be preferable to allow also changing theintegration time - but mitigate the scale impact by also changing the gainunderneath. Eg, if integration time change doubles the measured values,the driver can reduce the HW-gain to half.The theory of the computations of gain-time-scale is simple. However,some people (undersigned) got that implemented wrong for more than once.Hence some gain-time-scale helpers were introduced.Add some simple tests to verify the most hairy functions.Signed-off-by: Matti Vaittinen Link: https://lore.kernel.org/r/0f7505b43f91394dc3bb636369489c897b7e01a7.1705328293.git.mazziesaccount@gmail.comSigned-off-by: Jonathan Cameron List of files: /linux-6.15/drivers/iio/test/Makefile

iio: test: format: follow CONFIG_ naming conventionThe KUnit documentation indicates that all KUnit Kconfig entries mustmatch CONFIG__KUNIT_TEST: where is the name of the testsuite. Rename the IIO_TEST_FORMAT configuration accordingly.Signed-off-by: Liam Beguin Link: https://lore.kernel.org/r/20220710013109.3349104-4-liambeguin@gmail.comSigned-off-by: Jonathan Cameron List of files: /linux-6.15/drivers/iio/test/Makefile

8e74a48d - iio: test: add basic tests for the iio-rescale driver

Sun, 13 Feb 2022 02:57:35 +0000

iio: test: add basic tests for the iio-rescale driverThe iio-rescale driver supports various combinations of scale types andoffsets. These can often result in large integer multiplications. Makesure these calculations are done right by adding a set of kunit testcases that build on top of iio-test-format.To run these tests, add the following to .kunitconfig $ cat .kunitconfig CONFIG_IIO=y CONFIG_IIO_RESCALE_KUNIT_TEST=y CONFIG_KUNIT=yThen run: $ ./tools/testing/kunit/kunit.py run --kunitconfig .kunitconfigSigned-off-by: Liam Beguin Reviewed-by: Peter Rosin Reviewed-by: Andy Shevchenko Link: https://lore.kernel.org/r/20220213025739.2561834-7-liambeguin@gmail.comSigned-off-by: Jonathan Cameron List of files: /linux-6.15/drivers/iio/test/Makefile

0bf49ffb - iio: Add basic unit test for iio_format_value()

Tue, 15 Dec 2020 19:17:43 +0000

iio: Add basic unit test for iio_format_value()The IIO core provides a function to do formatting of fixedpoint numbers.In the past there have been some issues with the implementation of thefunction where for example negative numbers were not handled correctly.Introduce a basic unit test based on kunit that tests the function andensures that the generated output matches the expected output.This gives us some confidence that future modifications to the functionimplementation will not break ABI compatibility.To run the unit tests follow the kunit documentation and add CONFIG_IIO=y CONFIG_IIO_TEST_FORMAT=yto the .kunitconfig and run > ./tools/testing/kunit/kunit.py run Configuring KUnit Kernel ...
