linux-kselftest-4.10-rc1-update
This update consists of:
-- New tests to exercise the Sync Kernel Infrastructure. These tests
are part of a battery of Android libsync tests and are re-written
to test the new sync user-space interfaces from Emilio López, and
Gustavo Padovan.
-- Test to run hw-independent mock tests for i915.ko from Chris Wilson
-- A new gpio test case from Bamvor Jian Zhang
-- Missing gitignore additions
selftest/gpio: add gpio test case
This test script try to do whitebox testing for gpio subsystem(based on
gpiolib). It manipulate gpio device through chardev or sysfs and check
the result from debugfs. This script test gpio-mockup through chardev by
default. User could test other gpio chip by passing the module name.
Some of the testcases are turned off by default to avoid the conflicting
with gpiochip in system.
In details, it test the following things:
1. Test direction and output value for valid pin.
2. Test dynamic allocation of gpio base.
3. Add single, multi gpiochip to do overlap check.
Run "tools/testing/selftests/gpio/gpio-mockup.sh -h" for usage.
