This patch adds tests for following 22 implemented rtc ioctls:
* RTC_AIE_ON * RTC_ALM_SET * RTC_WKALM_SET
* RTC_AIE_OFF * RTC_ALM_READ * RTC_WKALM_RD
* RTC_UIE_ON * RTC_RD_TIME * RTC_PLL_GET
* RTC_UIE_OFF * RTC_SET_TIME * RTC_PLL_SET
* RTC_PIE_ON * RTC_IRQP_READ * RTC_VL_READ
* RTC_PIE_OFF * RTC_IRQP_SET * RTC_VL_CLR
* RTC_WIE_ON * RTC_EPOCH_READ
* RTC_WIE_OFF * RTC_EPOCH_SET
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/rtc-ioctl-tests/"
There are two folders located in the test folder, one for test that was written
manually ("/manual-test") and one the test that was obtained remotely ("/remote-test").
Manual test:
This test was written manually to test all the implemented rtc ioctls and
was added at "/manual-test/rtc-ioctl-manual-test.c". A separate test function
was written for each ioctl. Each of these functions uses a global test macro
'TEST_RTC_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 './rtc-ioctl-manual-test RTC_AIE_ON' tests only the ioctl RTC_AIE_ON
running './rtc-ioctl-manual-test RTC_AIE_ON RTC_SET_TIME RTC_ALM_READ' tests
ioctls RTC_AIE_ON, RTC_SET_TIME, RTC_ALM_READ
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 test, a remote rtc ioctl test was added at
"/remote-test/rtc-test.c". The test file "rtc-test.c" was downloaded
from linux kernel and is located at "linux/drivers/rtc/rtc-test.c".
This file was modified a little bit so that it doesn't have styling
problems identified by "scripts/checkpatch.pl". It is used to further
test functionalities of some rtc ioctls by running rtc clock at different
frequencies.

From: Filip Bozuta @ 2020-02-13 14:25 UTC (permalink / raw)
To: qemu-devel; +Cc: alex.bennee, laurent
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'.
