2019-04-25	selftests: Add test plan API to kselftest.h and adjust callers	Kees Cook	1	-1/+2
	The test plan for TAP needs to be declared immediately after the header. This adds the test plan API to kselftest.h and updates all callers to declare their expected test counts. Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
2017-11-15	selftests: breakpoints: fix compile error on breakpoint_test_arm64	Sumit Semwal	1	-0/+1
	The current mainline breakpoints test for arm64 fails to compile with breakpoint_test_arm64.c: In function ‘set_watchpoint’: breakpoint_test_arm64.c:97:28: error: storage size of ‘dreg_state’ isn’t known struct user_hwdebug_state dreg_state; Adding a direct include for asm/ptrace.h helps it to build, and passes the test on mainline on hikey.

2017-06-30	selftests: breakpoints: breakpoint_test_arm64: convert test to use TAP13	Shuah Khan	1	-36/+58
	Convert breakpoint_test_arm64 output to TAP13 format. Use ksft_* var arg msg api to include strerror() info. in the output. Change output from child process to use ksft_print_msg() instead of ksft_exit_* to avoid double counting tests and ensure parent process does the test counter incrementing.

2017-06-15	kselftest: make callers of ksft_exit_skip() output the reason for skipping	Paul Elder	1	-2/+1
	Make the three tests that did use the old ksft_ext_skip() (breakpoints/breakpoint_test_arm64, breakpoints/step_after_suspend_test, and membarrier_test) use the new one, with an output for the reason for skipping all the tests.

2016-11-18	selftests: arm64: add test for unaligned/inexact watchpoint handling	Pratyush Anand	1	-0/+236
	ARM64 hardware expects 64bit aligned address for watchpoint invocation. However, it provides byte selection method to select any number of consecutive byte set within the range of 1-8. This patch adds support to test all such byte selection option for different memory write sizes. Patch also adds a test for handling the case when the cpu does not report an address which exactly matches one of the regions we have been watching (which is a situation permitted by the spec if an instruction accesses both watched and unwatched regions). The test was failing on a MSM8996pro before this patch series and is passing now.
