selftests/powerpc: Fix resource leaks

2022-12-05T10:39:15Z

In check_all_cpu_dscr_defaults, opendir() opens the directory stream. Add missing closedir() in the error path to release it. In check_cpu_dscr_default, open() creates an open file descriptor. Add missing close() in the error path to release it.

selftests/powerpc: Don't run DSCR tests on old systems

2020-09-08T12:24:02Z

The DSCR tests fail on systems that don't have DSCR, so check for the DSCR in hwcap and skip if it's not present. Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/20200819015727.1977134-5-mpe@ellerman.id.au

selftests/powerpc: Use snprintf to construct DSCR sysfs interface paths

2017-10-06T09:51:10Z

Currently sprintf is used, and while paths should never exceed the size of the buffer it is theoretically possible since dirent.d_name is 256 bytes. As a result this trips -Wformat-overflow, and since the test is built with -Wall -Werror the causes the build to fail. Switch to using snprintf and skip any paths which are too long for the filename buffer. Signed-off-by: Seth Forshee Signed-off-by: Michael Ellerman

selftests/powerpc: Add test for all DSCR sysfs interfaces

2015-06-07T09:37:58Z

This test continuously updates the system wide DSCR default value in the sysfs interface and makes sure that the same is reflected across all the sysfs interfaces for each individual CPUs present on the system. Acked-by: Shuah Khan Signed-off-by: Anshuman Khandual Signed-off-by: Michael Ellerman
