This patch adds tests for following 14 implemented alsa timer ioctls: * SNDRV_TIMER_IOCTL_PVERSION * SNDRV_TIMER_IOCTL_INFO * SNDRV_TIMER_IOCTL_NEXT_DEVICE * SNDRV_TIMER_IOCTL_PARAMS * SNDRV_TIMER_IOCTL_TREAD * SNDRV_TIMER_IOCTL_STATUS * SNDRV_TIMER_IOCTL_GINFO * SNDRV_TIMER_IOCTL_START * SNDRV_TIMER_IOCTL_GPARAMS * SNDRV_TIMER_IOCTL_STOP * SNDRV_TIMER_IOCTL_GSTATUS * SNDRV_TIMER_IOCTL_CONTINUE * SNDRV_TIMER_IOCTL_SELECT * SNDRV_TIMER_IOCTL_PAUSE Names and descriptions of these ioctls can be found in patches that implement them. Test folder for these ioctl tests is located at "tests/tcg/multiarch/alsa-timer-ioctl-tests/" There are two folders located in the test folder, one for test that was written manually ("/manual-test") and one for the test that was obtained remotely ("/remote-test"). Manual test: This test was written manually to test all the implemented alsa timer ioctls and was added at "/manual-test/alsa-timer-ioctl-manual-test.c". A separate test function was written for each ioctl. Each of these functions uses a global test macro 'TEST_ALSA_IOCTL' to run these tests. The file can be run to test all ioctls or it can test only the specified ioctls. This depends on the commands specified when running the test. For Example (assuming 'rtc-ioctl-manual-test' is the compiled .exe file): running './alsa-timer-ioctl-manual-test SNDRV_TIMER_IOCTL_TREAD' tests only the ioctl SNDRV_TIMER_IOCTL_TREAD running './alsa-timer-ioctl-manual-test SNDRV_TIMER_IOCTL_INFO SNDRV_TIMER_IOCTL_STOP SNDRV_TIMER_IOCTL_PAUSE' tests ioctls SNDRV_TIMER_IOCTL_INFO, SNDRV_TIMER_IOCTL_STOP, SNDRV_TIMER_IOCTL_PAUSE If no ioctl is specified when running the test file, all the ioctls are tested: running './rtc-ioctl-test' tests all ioctls Remote test: Besides the manual tests, a remote alsa timer ioctl test was added at "/remote-test/timer.c". This test file was downloaded from a git repository that contains alsa ioctl test suite. This repository is located at "https://github.com/takaswie/alsa-ioctl-test". It is used to test all of the alsa timer ioctls at once by running a test macro defined in that file. The file was modified a little bit by adding an output line that shows which test passed and at which test the program aborts. It was also modified so that it doesn't have styling problems detected by 'scripts/checkpatch.pl'.
