[RFC PATCH] rtc: remove 'setdate' test program

by Wolfram Sang

The tool is not embedded in the testing framework. 'rtc' from rtc-tools serves as a much better programming example. No need to carry this tool in the kernel tree.

[PATCH] selftest: rtc: skip some tests if the alarm only supports minutes

by Wolfram Sang

There are alarms which have only minute-granularity. The RTC core already has a flag to describe them. Use this flag to skip tests which require the alarm to support seconds. Signed-off-by: Wolfram Sang <wsa+renesas(a)sang-engineering.com> --- Tested with a Renesas RZ-N1D board. This RTC obviously has only minute resolution for the alarms. Output now looks like this: # RUN rtc.alarm_alm_set ... # SKIP Skipping test since alarms has only minute granularity. # OK rtc.alarm_alm_set ok 5 rtc.alarm_alm_set # SKIP Skipping test since alarms has only minute granularity.

[PATCH] kunit: fixes Compilation error on s390

by Alessandro Carminati

The current implementation of suppressing warning backtraces uses __func__, which is a compile-time constant only for non -fPIC compilation. GCC's support for this situation in position-independent code varies across versions and architectures. On the s390 architecture, -fPIC is required for compilation, and support for this scenario is available in GCC 11 and later.

[PATCH v2] selftests/mm: Convert page_size to unsigned long

by Siddarth G

Cppcheck warning: int result is assigned to long long variable. If the variable is long long to avoid loss of information, then you have loss of information. This patch changes the type of page_size from 'unsigned int' to 'unsigned long' instead of using ULL suffixes. Changing hpage_size to 'unsigned long' was considered, but since gethugepage() expects an int, this change was avoided. Similarly, wp_init(), wp_free(), wp_addr_range() are designed to accept int parameters, even though they are assigned with long values. Future updates to these functions might be required ?
