[PATCH 1/2] tests/tcg/multiarch: Add tests for implemented rtc ioctls |
|
Date: |
Mon, 20 Jan 2020 17:09:13 +0100 |
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/"
Tests for individual ioctls are located in separate folders. These
folders are arranged by the same way these ioctls are implemented
in patches. These test files are simple programs that use these ioctls
to set/read or turn on/off some rtc features.
Besides tests for individual ioctls, a global rtc ioctl test was
added at "tests/tcg/multiarch/rtc-ioctl-tests/GlobalTest/rtc-test.c"
This test file 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.
